Effect of infarct location and volume on cognitive dysfunction in elderly patients with acute insular cerebral infarction

BACKGROUND The aging of the population has become increasingly obvious in recent years,and the incidence of cerebral infarction has shown an increasing trend annually,with high death and disability rates.AIM To analyze the effects of infarct location and volume on cognitive dysfunction in elderly patients with acute insular cerebral infarction.METHODS Between January 2020 and December 2023,we treated 98 cases of elderly acute insula,patients with cerebral infarction in the cerebral infarction acute phase(3-4 weeks)and for the course of 6 months in Montreal Cognitive Assessment Scale(MoCA)for screening of cognition.Notably,58 and 40 patients were placed in the cognitive impairment group and without-cognitive impairment group,respec-tively.In patients with cerebral infarction,magnetic resonance imaging was used to screen and clearly analyze the MoCA scores of two groups of patients with different infarctions,the relationship between the parts of the infarction volume,and analysis of acute insula cognitive disorder in elderly patients with cerebral RESULTS The number of patients with cognitive impairment in the basal ganglia and thalamus was significantly higher than that without cognitive impairment(P<0.05).The total infarct volume in the cognitive impairment group was higher than that in the non-cognitive impairment group,and the difference was statistically significant(P<0.05).The infarct volumes at different sites in the cognitive impairment group was higher than in the non-cognitive impairment group(P<0.05).In the cognitive impairment group,the infarct volumes in the basal ganglia,thalamus,and mixed lesions were negatively correlated with the total MoCA score,with correlation coefficients of-0.67,-0.73,and-0.77,respectively.CONCLUSION In elderly patients with acute insular infarction,infarction in the basal ganglia,thalamus,and mixed lesions were more likely to lead to cognitive dysfunction than in other areas,and patients with large infarct volumes were more likely to develop cognitive dysfunction.The infarct volume in the basal ganglia,thalamus,and mixed lesions was significantly negatively correlated with the MoCA score.

Inflammation as a cause of acute myocardial infarction in patients with myeloproliferative neoplasm

Myeloproliferative neoplasms(MPN)are a group of diseases characterized by the clonal proliferation of hematopoietic progenitor or stem cells.They are clinically classifiable into four main diseases:chronic myeloid leukemia,essential thrombocythemia,polycythemia vera,and primary myelofibrosis.These pathologies are closely related to cardio-and cerebrovascular diseases due to the increased risk of arterial thrombosis,the most common underlying cause of acute myocardial infarction.Recent evidence shows that the classical Virchow triad(hypercoagulability,blood stasis,endothelial injury)might offer an explanation for such association.Indeed,patients with MPN might have a higher number and more reactive circulating platelets and leukocytes,a tendency toward blood stasis because of a high number of circulating red blood cells,endothelial injury or overactivation as a consequence of sustained inflammation caused by the neoplastic clonal cell.These abnormal cancer cells,especially when associated with the JAK2V617F mutation,tend to proliferate and secrete several inflammatory cytokines.This sustains a pro-inflammatory state throughout the body.The direct consequence is the induction of a pro-thrombotic state that acts as a determinant in favoring both venous and arterial thrombus formation.Clinically,MPN patients need to be carefully evaluated to be treated not only with cytoreductive treatments but also with cardiovascular protective strategies.

Dapagliflozin and sacubitril on myocardial microperfusion in patients with post-acute myocardial infarction heart failure and type 2 diabetes

BACKGROUND Coronary heart disease and type 2 diabetes mellitus(T2DM)frequently coexist,creating a complex and challenging clinical scenario,particularly when complicated with acute myocardial infarction(AMI).AIM To examine the effects of dapagliflozin combined with sakubactrovalsartan sodium tablets on myocardial microperfusion.METHODS In total,98 patients were categorized into control(n=47)and observation(n=51)groups.The control group received noxital,while the observation group was treated with dapagliflozin combined with noxital for 6 months.Changes in myocardial microperfusion,blood glucose level,cardiac function,N-terminal prohormone of brain natriuretic peptide(NT-proBNP)level,growth differentiation factor-15(GDF-15)level,and other related factors were compared between the two groups.Additionally,the incidence of major adverse cardiovascular events(MACE)and adverse reactions were calculated.RESULTS After treatment,in the observation and control groups,the corrected thrombolysis in myocardial infarction frame counts were 37.12±5.02 and 48.23±4.66,respectively.The NT-proBNP levels were 1502.65±255.87 and 2015.23±286.31 pg/mL,the N-terminal pro-atrial natriuretic peptide(NT-proANP)levels were 1415.69±213.05 and 1875.52±241.02 ng/mL,the GDF-15 levels were 0.87±0.43 and 1.21±0.56 g/L,and the high-sensitivity C-reactive protein(hs-CRP)levels were 6.54±1.56 and 8.77±1.94 mg/L,respectively,with statistically significant differences(P<0.05).The cumulative incidence of MACEs in the observation group was significantly lower than that in the control group(P<0.05).The incidence of adverse reactions was 13.73%(7/51)in the observation group and 10.64%(5/47)in the control group,with no statistically significant difference(P>0.05).CONCLUSION Dapagliflozin combined with nocinto can improve myocardial microperfusion and left ventricular remodeling and reduce MACE incidence in patients with post-AMI heart failure and T2DM.The underlying mechanism may be related to the reduction in the expression levels of NT-proANP,GDF-15,and hs-CRP.

Pulmonary embolism secondary to acute anterior ST-elevation myocardial infarction:a case report

Thrombophilia denotes a condition,whether acquired or hereditary,characterized by increased susceptibility to hypercoagulation.[1]This condition was first described in 1965,coinciding with the discovery of an inherited predisposition to venous thromboembolism(VTE)in patients deficient in antithrombin III.[2]While arterial and venous thromboses are common in hospitalized patients,acute myocardial infarction(AMI)and pulmonary embolism(PE)stand out as lifethreateningconditions.However,theoccurrenceof AMI complicated by PE is exceedingly rare,especially when considering cases where paradoxical embolism originating from a patent foramen ovale is absent.This report presents a case of AMI complicated with PE.A comprehensive understanding of the pathophysiology of this rare yet critical condition is important for ensuring prompt diagnosis and treatment.

Successful emergency surgical intervention in acute non-STsegment elevation myocardial infarction with rupture:A case report

BACKGROUND The incidence of acute myocardial infarction(AMI)is rising,with cardiac rupture accounting for approximately 2%of deaths in patients with acute ST-segment elevation myocardial infarction(STEMI).Ventricular free wall rupture(FWR)occurs in approximately 2%of AMI patients and is notably rare in patients with non-STEMI.Types of cardiac rupture include left ventricular FWR,ventricular septal rupture,and papillary muscle rupture.The FWR usually leads to acute cardiac tamponade or electromechanical dissociation,where standard resuscitation efforts may not be effective.Ventricular septal rupture and papillary muscle rupture often result in refractory heart failure,with mortality rates over 50%,even with surgical or percutaneous repair options.CASE SUMMARY We present a rare case of an acute non-STEMI patient who suffered sudden FWR causing cardiac tamponade and loss of consciousness immediate before undergoing coronary angiography.Prompt resuscitation and emergency open-heart repair along with coronary artery bypass grafting resulted in successful patient recovery.CONCLUSION This case emphasizes the risks of AMI complications,shares a successful treatment scenario,and discusses measures to prevent such complications.

One Case of Primary Thrombocythemia with Concealed Hypokalemia Complicated by Acute Myocardial Infarction

Medical history summary: Male, 47 years old, was admitted to the hospital due to “dizziness accompanied by chest tightness and pain for more than 8 days”. One week ago, the patient experienced chest tightness, chest pain accompanied by profuse sweating for 3 hours and underwent emergency percutaneous coronary intervention (PCI) at a local hospital. The procedure revealed left main stem occlusion with subsequent left main stem to left anterior descending artery percutaneous transluminal coronary angioplasty (PTCA). After the procedure, the patient experienced hemodynamic instability, recurrent ventricular fibrillation, and critical condition, thus transferred to our hospital for further treatment. Symptoms and signs: The patient is in a comatose state, unresponsive to stimuli, with bilateral dilated pupils measuring 2.0 mm, exhibiting reduced sensitivity to light reflex, and recurrent fever. Coarse breath sounds can be heard in both lungs, with audible moist rales. Irregular breathing pattern is observed, and heart sounds vary in intensity. No pathological murmurs are auscultated in any valve auscultation area. Diagnostic methods: Coronary angiography results at the local hospital showed complete occlusion of the left main stem, and left main stem to left anterior descending artery percutaneous transluminal coronary angioplasty (PTCA) was performed. However, the distal guidewire did not pass through. After admission, blood tests showed a Troponin T level of 1.44 ng/ml and a Myoglobin level of 312 ng/ml. The platelet count was 1390 × 109/L. Von Willebrand factor (vWF) activity was measured at 201.9%. Bone marrow aspiration biopsy showed active bone marrow proliferation and platelet clustering. The peripheral blood smear also showed platelet clustering. JAK-2 gene testing was positive, confirming the diagnosis of primary thrombocytosis. Treatment methods: The patient is assisted with mechanical ventilation and intra-aortic balloon counterpulsation to improve coronary blood flow. Electrolyte levels are closely monitored, especially maintaining plasma potassium levels between 4.0 and 4.5 mmol/l. Hydroxyurea 500 mg is administered for platelet reduction. Anticoagulants and antiplatelet agents are used rationally to prevent further infarction or bleeding. Antiarrhythmic, lipid-lowering, gastroprotective, hepatoprotective, and heart failure treatment are also provided. Clinical outcome: The family members chose to withdraw treatment and signed for discharge due to a combination of reasons, including economic constraints and uncertainty about the prognosis due to the long disease course. Acute myocardial infarction has gradually become one of the leading causes of death in our country. As a “green channel” disease, corresponding diagnostic and treatment protocols have been established in China, and significant progress has been made in emergency care. There are strict regulations for the time taken from the catheterization lab to the cardiac intensive care unit, and standardized treatments are provided to patients once they enter the intensive care unit. Research results show that the incidence of acute myocardial infarction in patients with primary thrombocythemia within 10 years is 9.4%. This type of disease is rare and difficult to cure, posing significant challenges to medical and nursing professionals. In order to benefit future patients, we have documented individual cases of treatment and nursing care for these patients. The research results show that these patients exhibit resistance to traditional oral anticoagulant drugs and require alternative anticoagulants. Additionally, there are significant differences in serum and plasma potassium levels among patients. Therefore, when making clinical diagnoses, it is necessary to carefully distinguish between the two. Particularly, nursing personnel should possess dialectical thinking when supplementing potassium levels in patients in order to reduce the incidence of malignant arrhythmias and mortality rates.

Development and validation of a nomogram model for predicting the risk of pre-hospital delay in patients with acute myocardial infarction

BACKGROUND Acute myocardial infarction(AMI)is a severe cardiovascular disease caused by the blockage of coronary arteries that leads to ischemic necrosis of the myocardium.Timely medical contact is critical for successful AMI treatment,and delays increase the risk of death for patients.Pre-hospital delay time(PDT)is a significant challenge for reducing treatment times,as identifying high-risk patients with AMI remains difficult.This study aims to construct a risk prediction model to identify high-risk patients and develop targeted strategies for effective and prompt care,ultimately reducing PDT and improving treatment outcomes.AIM To construct a nomogram model for forecasting pre-hospital delay(PHD)likelihood in patients with AMI and to assess the precision of the nomogram model in predicting PHD risk.METHODS A retrospective cohort design was employed to investigate predictive factors for PHD in patients with AMI diagnosed between January 2022 and September 2022.The study included 252 patients,with 180 randomly assigned to the development group and the remaining 72 to the validation group in a 7:3 ratio.Independent risk factors influencing PHD were identified in the development group,leading to the establishment of a nomogram model for predicting PHD in patients with AMI.The model's predictive performance was evaluated using the receiver operating characteristic curve in both the development and validation groups.RESULTS Independent risk factors for PHD in patients with AMI included living alone,hyperlipidemia,age,diabetes mellitus,and digestive system diseases(P<0.05).A characteristic curve analysis indicated area under the receiver operating characteristic curve values of 0.787(95%confidence interval:0.716–0.858)and 0.770(95%confidence interval:0.660-0.879)in the development and validation groups,respectively,demonstrating the model's good discriminatory ability.The Hosmer–Lemeshow goodness-of-fit test revealed no statistically significant disparity between the anticipated and observed incidence of PHD in both development and validation cohorts(P>0.05),indicating satisfactory model calibration.CONCLUSION The nomogram model,developed with independent risk factors,accurately forecasts PHD likelihood in AMI individuals,enabling efficient identification of PHD risk in these patients.

Use of Beta-Blocker in Acute ST-Elevation Myocardial Infarction

This paper reported beta-blocker use in 21 STEMI patients over four years. The patients were between 50 - 65 years of age presenting with anterior, lateral, and inferior STEMI (ST-Elevation Myocardial Infarction). Seven of the patients were female, and 14 were male. They presented to an emergency room of a rural hospital that did not provide emergency percutaneous coronary angioplasty/stenting (PTCA/stenting). The hospital is about 70 minutes from a facility that provided PTCA/ stenting—all the patients presented with typical angina chest pain with ST elevation. They are hemodynamic stable. Most patients received Lopressor 35 mg IVP, with one receiving 115 mg in a 5 mg increment. They were chest pain-free and hemodynamically before leaving the ER for the transfer for PTCA/stent. The results demonstrated that beta-blockers are effective in relieving pain in STEMI patients. Further study is needed to determine its efficacy, safety, and how to use it.

Circulating CCRR serves as potential novel biomarker for predicting acute myocardial infarction

Objective:Cold regions exhibit a high prevalence of cardiovascular disease,particularly acute myocardial infarction(AMI),which is one of the leading causes of death associated with cardiovascular conditions.Cardiovascular disease is closely linked to the abnormal expression of long non-coding RNA(lncRNA).This study investigates whether circulating levels of lncRNA cardiac conduction regulatory RNA(CCRR)could serve as a biomarker for AMI.Materials and methods:We measured circulating CCRR from whole blood samples collected from 68 AMI patients and 69 non-AMI subjects.An AMI model was established using C57BL/6 mice.Quantitative reverse transcription PCR(qRT-PCR)was used to assess CCRR expression.Exosomes were isolated from cardiomyocytes,and their characteristics were evaluated using electron microscope and nanoparticle tracking analysis.The exosome inhibitor GW4869 was employed to examine the effect of exosomal CCRR on cardiac function using echocardiography.Protein expression was detected using Western blot and immunofluorescence staining.Results:The circulating level of CCRR was significantly higher in AMI patients(1.93±0.13)than in non-AMI subjects(1.00±0.05,P<0.001).The area under the ROC curve(AUC)of circulating CCRR was 0.821.Similar changes in circulating CCRR levels were consistently observed in an AMI mouse model.Exosomal CCRR derived from hypoxia-induced cardiomyocytes and cardiac tissue after AMI were increased,a change that was reversed by GW4869.Additionally,CCRR-overexpressing exosomes improved cardiac function in AMI.Conclusion:Circulating lncRNA CCRR is a potential predictor of AMI.Exosomal CCRR plays a role in the communication between the heart and other organs through circulation.

The Effect of Different Hyperbaric Oxygen Treatment Time Windows on Neurological Function and Prognosis in Acute Cerebral Infarction

Objective:To observe the effects of different hyperbaric oxygen treatment time windows on the prognosis and neurological function of acute cerebral infarction.Method:160 patients with acute cerebral infarction admitted to Xiangyang Central Hospital in Hubei Province were randomly divided into four groups,each with 40 cases,using a random number table method.According to the 2017 guidelines for the treatment of cerebral infarction,the control group received routine treatment for acute cerebral infarction;On the basis of the control group,patients in Group A received hyperbaric oxygen therapy within 48 hours of onset;Group B patients receive hyperbaric oxygen therapy within 3-6 days of onset;Group C patients receive hyperbaric oxygen therapy within 7-12 days of onset.Observe the efficacy,recurrence,and neurological function recovery of four groups of patients after treatment.Result:There was no statistically significant difference in the National Institutes of Health Stroke Scale(NIHSS)and Barthel Index(BI)scores among the four groups before treatment(P>0.05).There were statistically significant differences in NIHSS and BI scores between 14 and 30 days after treatment and before treatment(F=16.352,27.261,11.899,28.326,P<0.05).At 14 and 30 days after treatment,the NIHSS score in Group A decreased compared to the control group,Group B,and Group C,while the BI score increased compared to the control group,Group B,and Group C,with statistical significance(P<0.05).There was no statistically significant difference in NIHSS and BI scores between Group C and the control group after treatment(P>0.05).After 30 days of treatment,the total effective rate of Group A was higher than that of the control group and Group C,and the difference was statistically significant(X2=6.135,P<0.05).The one-year recurrence rate of Group A and Group B is lower than that of Group C and the control group,and the difference is statistically significant(X2=8.331,P<0.05).There was no statistically significant difference in adverse reactions among the four groups(P>0.05).Conclusion:Patients with acute cerebral infarction who receive hyperbaric oxygen therapy within 48 hours can improve neurological function and reduce the recurrence rate.The efficacy of receiving hyperbaric oxygen therapy within 7-12 days of onset is equivalent to that of not receiving hyperbaric oxygen therapy.

The Effect of Predictive Nursing Intervention on Cardiac Function and Clinical Outcomes in CCU Patients with Acute Myocardial Infarction After Interventional Therapy

Objective:To evaluate the impact of predictive nursing on the care of acute myocardial infarction(AMI)patients in the Coronary Care Unit(CCU)after interventional therapy.Methods:From September 2021 to September 2023,84 AMI patients admitted to the CCU were randomly divided into two groups:the experimental group(42 patients)received predictive nursing,and the reference group(42 patients)received conventional nursing.Cardiac function and clinical outcomes were compared between the groups.Results:Before nursing,there was no difference in cardiac function between the two groups(P>0.05).After nursing,the cardiac function of the experimental group was better than that of the reference group(P<0.05).The clinical outcomes of the experimental group were better than those of the reference group(P<0.05).Before nursing,there was no difference in psychological scores between the two groups(P>0.05).After nursing,the psychological scores of the experimental group were lower than those of the reference group(P<0.05).Conclusion:Predictive nursing can improve the cardiac function and clinical outcomes of AMI patients after interventional therapy and can also regulate patients’negative psychological states.

A Study of the Causes of In-Hospital Mortality in Patients with Acute Myocardial Infarction Complicated by Gastrointestinal Haemorrhage

Objective:To analyze the risk factors for death during hospitalization in patients with acute myocardial infarction(AMI)complicated by gastrointestinal bleeding(GIB).Methods:260 patients with AMI complicated by GIB who were admitted to the cardiology department of a hospital from January 2022 to December 2023 were retrospectively analyzed.27 patients who died during hospitalization were designated as the control group and the 233 patients who survived as the observation group.Baseline data and clinical indexes of patients in the two groups were compared,and multifactorial logistic regression was applied to analyze the risk factors for death during hospitalization in patients with AMI complicated by GIB.Results:Univariate analysis showed that the control group had higher proportions of patients with Killip classification III to IV on admission,new arrhythmias,and mechanical complications,as well as higher heart rates,white blood cell counts,urea nitrogen,and creatinine levels.The proportion of patients who received transfusion therapy during hospitalization was also higher in the control group.Conversely,the control group had lower systolic and left ventricular ejection fraction rates compared to the observation group,with statistically significant differences(P<0.05).Multifactorial logistic regression analysis revealed that new-onset arrhythmia(OR=2.724,95%CI 1.289-5.759),heart rate>100 beats/min(OR=3.824,95%CI 1.472-9.927),left ventricular ejection fraction<50%(OR=1.884,95%CI 0.893-3.968),BUN level(OR=1.029,95%CI 1.007-1.052),and blood transfusion(OR=3.774,95%CI 1.124-6.345)were independently associated with an increased risk of death during hospitalization in patients with AMI complicated by GIB.Conclusions:New arrhythmia,heart rate>100 beats/min,left ventricular ejection fraction<50%,elevated BUN levels,and blood transfusion are risk factors for death during hospitalization in patients with AMI complicated by GIB.

Analysis of the Therapeutic Effect of Clopidogrel Bisulfate Tablets + Aspirin Enteric-Coated Tablets on Acute Myocardial Infarction

Objective:To investigate and analyze the clinical effect of clopidogrel bisulfate tablets combined with aspirin enteric-coated tablets on acute myocardial infarction(AMI)patients.Methods:The study period was from January 2020 to December 2023,the sample source was 82 AMI patients admitted to our hospital,grouped into an observation group(n=41)and a control group(n=41)by the numerical table method.The patients in the control group were treated with aspirin enteric-coated tablets,and the patients in the observation group were treated with aspirin enteric-coated tablets combined with clopidogrel bisulfate.The clinical efficacy,coagulation indexes,and the incidence of cardiovascular adverse events between the two groups were compared.Results:The clinical efficacy of the observation group was higher than that of the control group(P<0.05);the platelet aggregation rate(PAR)of the observation group was lower than that of the con-trol group after treatment(P<0.05),and there was no significant difference in the prothrombin time(PT)and activated partial thromboplastin time(APTT)between the two groups(P>0.05).The incidence of cardiovascular adverse events in the observation group was lower than that of the control group(P<0.05).Conclusion:The treatment effect of clopidogrel bisulfate tablets combined with aspirin enteric-coated tablets on AMI patients is remarkable.It reduces the PAR and the incidence of cardiovascular adverse events,so this treatment method should be popularized.

A Comparative Study of Risk Factors and Prognosis in Young and Elderly Patients with Acute ST-Segment Elevation Myocardial Infarction

Objective:To investigate the differences in risk factors and prognosis between young and elderly patients with acute ST-segment elevation myocardial infarction(STEMI)so as to provide a basis for the prevention of young patients with acute STEMI.Methods:Patients initially diagnosed with STEMI in the 920"Hospital of Joint Logistic Support Force of PLA from January 1,2018 to December 31,2022 were retrospectively enrolled in this study.A total of 235 STEMI patients aged≤45 years old and 532 STEMI patients aged≥65 years old were screened.The baseline characteristics,laboratory indicators,clinical characteristics,coronary angiography,SYNTAX score and major adverse cardiovascular events(MACE)during 1-year follow-up were analyzed and compared.Results:A total of 767 STEMI patients were enrolled,including 235 in the young group and 532 in the elderly group.Among the STEM patients in the young group,224 cases were male,and smoking and drinking were common.Compared with the elderly group,the young group had shorter hospital stays and more family history of ischemic heart disease(IHD).The level of low-density lipoprotein in the young group was higher than that in the old group,while the level of high-density lipoprotein in the young group was lower than that in the old group.The level of high uric acid and homocysteine in the young group was significantly higher than that in the old group.The main cause of STEMI in the young group was fatigue,and the most common symptom was angina pectoris.Coronary angiography showed that single vessel disease was more common in the young group than in the elderly group,and the lesion in the young group was the left anterior descending artery.The SYNTAX score was significantly lower in the young group than in the elderly group according to the anatomical characteristics of coronary artery disease.In the forest plot,diabetes mellitus and a family history of IHD showed a trend of major adverse cardiovascular events(MACE)in both groups.Conclusion:Males,smokers,alcohol drinkers and family history of ischemic heart disease are more common in young patients.Common risk factors include fatigue,hyperuricemia,hyperlipidemia and so on.In addition,age itself is an independent risk factor.Management of diabetes,hyperuricemia,and homocysteine levels is essential to reduce the incidence of cardiovascular events in young patients.By controlling these factors,the incidence of young patients with acute STEMI can be effectively prevented and the corresponding prevention and treatment basis can be provided.

Analysis of mental health status and related factors in patients with acute cerebral infarction

BACKGROUND Acute cerebral infarction(ACI)is characterized by a high incidence of morbidity,disability,recurrence,death and heavy economic burden,and has become a disease of concern in global researchers.As ACI has serious effects on patients’physical status,life and economy,often causing anxiety,depression and other psychological problems,these problems can lead to the aggravation of physical symptoms;thus,it is very important to understand the factors affecting the mental health of these patients.AIM To understand the elements that affect the mental health of patients who have suffered an ACI.METHODS A questionnaire survey was conducted among patients with ACI admitted to three tertiary hospitals(Quanzhou First Hospital,Fuqing City Hospital Affiliated to Fujian Medical University,and the 900 Hospital of the Joint Service Support Force of the People’s Liberation Army of China)in Fujian Province from January 2022 to December 2022 using the convenience sampling method.ACI inpatients who met the inclusion criteria were selected.Informed consent was obtained from the patients before the investigation,and a face-to-face questionnaire survey was conducted using a unified scale.The questionnaire included a general situation questionnaire,Zung’s self-rating depression scale and Zung’s self-rating anxiety scale.All questionnaires were checked by two researchers and then the data were input and sorted using Excel software.The general situation of patients with ACI was analyzed by descriptive statistics,the influence of variables on mental health by the independent sample t test and variance analysis,and the influencing factors on psychological distress were analyzed by multiple stepwise regression.RESULTS The average age of the 220 patients with ACI was 68.64±10.74 years,including 142 males and 78 females.Most of the patients were between 60 and 74 years old,the majority had high school or technical secondary school education,most lived with their spouse,and most lived in cities.The majority of patients had a personal income of 3001 to 5000 RMB yuan per month.The new rural cooperative medical insurance system had the largest number of participants.Most stroke patients were cared for by their spouses and of these patients,52.3%had previously smoked.Univariate analysis showed that gender,age,residence,course of disease,number of previous chronic diseases and smoking history were the main factors affecting the anxiety scores of patients with ACI.Age,living conditions,monthly income,course of disease and knowledge of disease were the primary variables influencing the depression score in patients with ACI.The findings of multivariate analysis revealed that the course of disease and gender were the most important factors influencing patients’anxiety scores,and the course of disease was also the most important factor influencing patients’depression scores.CONCLUSION Long disease course and female patients with ACI were more likely to have psychological problems such as a high incidence of emotional disorders.These groups require more attention and counseling.

Relationship between primary caregivers’social support function,anxiety,and depression after interventional therapy for acute myocardial infarction patients

BACKGROUND An acute myocardial infarction(AMI)is often treated with direct coronary intervention and requires home-based rehabilitation.Caregivers of patients with AMI need adequate social support to maintain high-quality care;however,their social support function is low,and relevant indicators for intervention must be identified.AIM To analyze the correlation between social support for primary caregivers,their anxiety,and depression,when caring for patients with AMI after interventional therapy.METHODS Using convenience sampling,we selected 300 primary caregivers of patients with AMI who had undergone interventional therapy.The Social Support Rating Scale(SSRS),Self-Rating Anxiety Scale(SAS),and Self-Rating Depression Scale(SDS)were used to assess the primary caregivers.A Pearson’s correlation analysis was used to analyze the correlations between the SSRS,SAS,and SDS,and a multiple logistic regression analysis was used to analyze the factors influencing the low social support function of primary caregivers.The receiver operating characteristic curve and area under the curve(AUC)were used to evaluate the predictive ability of the SAS and SDS for low social support function in primary caregivers.RESULTS Considering the norm among Chinese people,AMI caregivers’objective support,subjective support,support utilization,and SSRS scores were lower,while their SAS and SDS scores were higher.The SSRS scores of female caregivers were higher than those of the male caregivers(t=2.123,P=0.035).The Pearson correlation analysis showed that objective support,subjective support,support utilization,and SSRS total scores were significantly correlated with both SAS(r=-0.414,-0.460,-0.416,-0.535)and SDS scores(r=-0.463,-0.379,-0.349,-0.472).Among the 300 AMI caregivers,56 cases(18.67%)had a low level of support function(SSRS≤22 points).Logistic regression model analysis showed that SAS and SDS were independent risk factors for low social support function of AMI caregivers,regardless of adjustment for other variables(P<0.05).SAS and SDS predicted that the AUC of AMI caregivers with low support function was 0.84,sensitivity was 67.9 and 71.4,and specificity was 84.0 and 70.9,respectively.CONCLUSION The social support function of the primary caregiver of patients with AMI after interventional therapy was lower and negatively correlated with anxiety and depression in the primary caregiver.

Acute myocardial infarction in myeloproliferative neoplasms

Myeloproliferative neoplasms(MPNs)are a heterogeneous group of hematologic malignancies characterized by an abnormal proliferation of cells of the myeloid lineage.Affected individuals are at increased risk for cardiovascular and thrombotic events.Myocardial infarction(MI)may be one of the earliest clinical manifestations of MPNs or may be a thrombotic complication that develops during the natural course of the disease.In the present review,we examine the epidemiology,pathogenesis,clinical presentation,and management of MI in MPNs based on the available literature.Moreover,we review potential biomarkers that could mediate the MI-MPNs crosstalk,from classical biochemical tests,e.g.,lactate dehydrogenase,creatine kinase and troponins,to pro-inflammatory cytokines,oxidative stress markers,and clonal hematopoiesis.

Long-Term Prognosis of Different Reperfusion Strategies for ST-Segment Elevation Myocardial Infarction in Chinese County-Level Hospitals:Insight from China Acute Myocardial Infarction Registry

Objective To evaluate the long-term prognosis of patients with ST-segment elevation myocardial infarction(STEMI)treated with different reperfusion strategies in Chinese county-level hospitals Methods A total of 2,514 patients with STEMI from 32 hospitals participated in the China Acute Myocardial Infarction registry between January 2013 and September 2014.The success of fibrinolysis was assessed according to indirect measures of vascular recanalization.The primary outcome was 2-year mortality.Results Reperfusion therapy was used in 1,080 patients(42.9%):fibrinolysis(n=664,61.5%)and primary percutaneous coronary intervention(PCI)(n=416,38.5%).The most common reason for missing reperfusion therapy was a prehospital delay>12 h(43%).Fibrinolysis[14.5%,hazard ratio(HR):0.59,95%confidence interval(CI)0.44–0.80]and primary PCI(6.8%,HR=0.32,95%CI:0.22–0.48)were associated with lower 2-year mortality than those with no reperfusion(28.5%).Among fibrinolysistreated patients,510(76.8%)achieved successful clinical reperfusion;only 17.0%of those with failed fibrinolysis underwent rescue PCI.There was no difference in 2-year mortality between successful fibrinolysis and primary PCI(8.8%vs.6.8%,HR=1.53,95%CI:0.85–2.73).Failed fibrinolysis predicted a similar mortality(33.1%)to no reperfusion(33.1%vs.28.5%,HR=1.30,95%CI:0.93–1.81).Conclusion In Chinese county-level hospitals,only approximately 2/5 of patients with STEMI underwent reperfusion therapy,largely due to prehospital delay.Approximately 30%of patients with failed fibrinolysis and no reperfusion therapy did not survive at 2 years.Quality improvement initiatives are warranted,especially in public health education and fast referral for mechanical revascularization in cases of failed fibrinolysis.

A Case of Acute Upper Gastrointestinal Bleeding in Liver Cirrhosis Complicated by Acute Cerebral Infarction and Acute Myelitis

Background: Acute upper gastrointestinal bleeding in liver cirrhosis combined with acute cerebral infarction is uncommon in clinical work, and then combined with acute myelitis is even rarer and more complex, which poses a greater challenge to clinical diagnosis and treatment. This paper reports a case of acute upper gastrointestinal bleeding in liver cirrhosis complicated by acute cerebral infarction and acute myelitis, which be hoped to provide a reference for clinical work. Methods: We retrospectively evaluated the clinical information of a 68-year-old female admitted to the Digestive Medical Department with acute gastrointestinal bleeding and appeared limb movement disorder on the third day. Results: The patient was eventually diagnosed with acute upper gastrointestinal bleeding in liver cirrhosis complicated by acute cerebral infarction and acute myelitis. Conclusions: When patients with liver cirrhosis have abnormal neurological symptoms, in addition to liver cirrhosis-related complications, doctors need to consider cerebrovascular diseases and myelitis.

Spontaneous Heparin-Induced Thrombocytopenia Presenting as Concomitant Bilateral Cerebrovascular Infarction and Acute Coronary Syndrome

Background:Spontaneous heparin-induced thrombocytopenia is a pro-thrombotic syndrome in which anti-heparin antibodies develop without heparin exposure.Case presentation:A 78-year-old man who underwent a successful lumbar laminectomy presented to the hospital 5 days after discharge for stroke-like symptoms and was found to have acute infarcts of the bilateral frontal lobes.The patient was found to be severely thrombocytopenic and was incidentally found to have an inferior wall myocardial infarction.Further investigation led to the diagnosis of bilateral lower extremity deep vein thromboses.His overall clinical presentation prompted a detailed hematologic workup that indicated positivity for heparin-induced thrombocy-topenia despite no previous exposure to heparin products.Conclusions:This case illustrates a patient with no prior lifetime heparin exposure who underwent laminectomy with subsequent development of acute infarcts of the bilateral frontal lobes,an inferior wall myocardial infarction,and bilateral lower extremity deep vein thromboses,with concern for sequelae of spontaneous heparin-induced thrombo-cytopenia.
