Prompt and accurate monitoring of cardiovascular and accompanying hemodynamic changes is crucial in achieving adequate management of the condition. Advances in technology has availed procedures such as pulse index continuous cardiac output (PiCCO), which can offer precise monitoring of cardiovascular functions and hemodynamic parameters. In this study, PiCCO is evaluated for its potential utility in improving management and clinical outcomes among elderly patients with AMI complicated by CS. AIM To assess whether use of the PiCCO system can improve clinical outcomes in elderly patients with AMI complicated by CS.METHODS Patients from emergency intensive care units (EICU) or coronary care units (CCU) were randomized to receive PiCCO monitoring or not. The APACHE II score, SOFA score, hs-TnI, NT-proBNP, PaO2/FiO2 ratio and lactate levels on day 1, 3 and 7 after treatment were compared. The infusion and urine volume at 0-24 h, 24-48 h and 48-72 h were recorded, as were the cardiac index (CI), extravascular lung water index (EVLWI), intrathoracic blood volume index (ITBVI) and global end diastolic volume index (GEDVI) at similar time intervals. RESULTS Sixty patients with AMI complicated by CS were included in the study. The PiCCO group had a significantly lower APACHE II score, SOFA score, hs-TnI and NT-proBNP levels on day 1, 3 and 7 after treatment. The infusion and urine volume during 0-24 h in the PiCCO group were significantly greater, and this group also showed significantly higher ADL scores. Furthermore, the PiCCO group spent lesser days on vasoactive agents, mechanical ventilation, and had a reduced length of stay in EICU/CCU. Additionally, the CI was significantly higher at 48 h and 72 h in the PiCCO group compared with that at 24 h, and the EVLWI, ITBVI and GEDVI were significantly decreased at 48 h and 72 h. CONCLUSION Applying the PiCCO system could improve the clinical outcomes of elderly patients with AMI complicated by CS.展开更多

Methods A total of 42 AMI patients with cardiogenic shock were retrospectively studied. BNP plasma level was recorded in the 24th hour and 4th day after myocardial infarction. The different mortality were compared among patients with different BNP levels. Results With aggressive treatment, 20 patients survived short term hospitalization. Plasma concentration of BNP in dying patients is much higher than in survivals(1369 ± 353 vs 651 ± 302 pg/ml. P〈 0.01).Patients with BNP higher than 1474 pg/mL had a mortality of 92.9 %. Conclusions Elevated BNP level in AMI patients with cardiogenic shock treated with IABP is highly associated with poor prognosis.展开更多

Methods: We recruited 14 consecutive patients with cardiogenic shock (10 men, 69 ± 12 years) and 18 well-matched baseline characteristics without shock (17 men, 64 ± 9 years) undergoing percutaneous coronary intervention (PCI) for an early phase of a first anterior STEMI in whom plasma level of cardiac enzyme was less elevated. We measured systemic and coronary levels of C-reactive protein, interleukin-6, and angiotensin II, and evaluated the relation of those to myocardial tissue-level reperfusion using both angiographic myocardial blush grade from 0 to 3, with the highest grade indicating normal myocardial perfusion, and a resolution of the sum of ST-segment elevation in 12-lead electrocardiogram. Results: In-hospital mortality was 57% in patients with cardiogenic shock and 6% without shock (p = 0.005). Coronary levels of C-reactive protein (9.2 ± 6.9 vs. 1.7 ± 2.1 mg/L, p = 0.001), interleukin-6 (379 ± 137 vs. 24 ± 20 pg/mL, p = 0.003), and angiotensin II (19 ± 10 vs. 10 ± 6 pg/mL, p = 0.010) were extremely higher in patients with shock than without shock. Interleukin-6 and angiotensin II, but not C-reactive protein, revealed higher in coronary levels than in systemic levels. The presence of both myocardial blush grade el reperfusion (p = 0.012). Conclusions: The exaggerated systemic and coronary inflammation, presumably associated with myocardial mal-reperfusion, was presented in patients with a cardiogenic shock complicating first anterior STEMI.展开更多

Background: Little is known about prognosis of CS from non-ischemic cardiomyopathy. Methods: Retrospective monocentric study of patients referred to an ICU during 2 years. Results: Despite aggressive management including intra-aortic balloon pump (31%), extra-renal replacement therapy (36%), extra-corporeal life support (8%), and catecholamine infusion (97%), in-hospital mortality was 46%. Toxic CS or CS related to deficiency carried a better outcome (mortality 5%). Post-myocardial infarction or post-cardiac arrest CS was associated with higher mortality. In the multivariate analyses, only SAPS II (OR 1.037;1.013 - 1.056;p = 0.0001), pulmonary hypertension (OR 4.8;1.3 - 17;p = 0.02), extra-renal replacement therapy (OR 2.9;1.3 - 6;p = 0.006), and dobutamine infusion (OR 0.44;0.2 - 0.96;p = 0.04) were significantly associated with in-hospital mortality. Conclusion: Dobutamine infusion was associated with a better outcome. Higher SAPS II, pulmonary hypertension, and extra-renal replacement therapy were associated with increased in-hospital mortality.展开更多

The observed blunted response to corticotropin was interpreted as impaired secretory reserve of the adrenal glands and was termed as relative adrenocortical insufficiency. Aim of the work: To study the incidence of adrenal insufficiency in patients developed cardiogenic shock complicating ST segment elevation myocardial infarction. Materials and methods: Prospective cohort study was done for 90 patients admitted to Algalaa Hospital for whom basal cortisol and ACTH level were measured immediately before a standard-dose (250 μg) ACTH stimulation test (SST) and 60 minutes after SST Δmax is defined as the difference between the maximal value after the test and basal level of serum cortisol. Results: Baseline ACTH and total cortisol showed positive correlation to clinical severity scores (APACHE II and Lactate), LVEF as well as vasoactive inotrope score, all with significant p value (0.000). The higher baseline cortisol level was co-related to increased mortality (Baseline serum cortisol level was significantly lower in survivors (30.6 ± 6.1 vs 45.0 ± 16.3) p value: 0.000) while the better response of the adrenal gland to short stimulation test was co-related more to survival as detected by Δmax TC (difference of cortisol level before and after SST) (13.8 ±3.8 in survivors vs 8.5 ± 4.42 in non survivors) p value 0.000. Conclusion: A high baseline plasma TC was associated with increased mortality in patients with cardiogenic shock post acute myocardial infarction. Patients with lower baseline TC, but with a better adrenal response, appeared to have a survival benefit.展开更多

She was found to be in cardiogenic shock. Her initial EKG was concerning for STEMI and her troponin was positive. She was eventually diagnosed with spontaneous coronary artery dissection. This case report discusses her presentation, management, and clinical course. We emphasize the need for emergency medicine physicians to be concerned for SCAD, especially in women with a history of fibromuscular dysplasia, connective tissue disorders, or peri-partum status.展开更多

However, little evidence is available on the optimal order of IABP insertion and primary PCI. The aim of this study was to investigate the impact of the sequence of IABP support and PC1 and its association with major adverse cardiac and cerebrovascular events (MACCEs). Methods: Data were obtained from 218 consecutive patients with CS due to STEMI in Beijing Anzhen Hospital between 2008 and 2014% who were treated with 1ABP and PCI. The patients were divided into two groups: Group A in whom IABP received before PCI (n = 106) and Group B in whom IABP received after PCI (n = 112). We evaluated the myocardial perfusion using myocardial blush grade and resolution of ST-segment elevation. The primary endpoint was 12-month risk of MACCE. Results: Most baseline characteristics were similar in patients between the two groups. However, patients received 1ABP before PCI were associated with a delay of door-to-balloon time (DBT) and higher troponin I level (P 〈 0.05). However, myocardial perfusion was significantly improved in patients treated with IABP before PCI (P 〈 0.05). Overall, IABP support before PCI was not associated with significantly lower risk of MACCE (P 〉 0.05). In addition, risk of all-cause mortality, bleeding, and acute kidney injury (AKI) was similar between two groups (P 〉 0.05). Multivariate analysis showed that DBT (odds ratio [OR] 2.5, 95% confidence interval [C/] 1.1-4.8, P=0.04), lABP support after PCI (OR 5.7, 95% Cl 2.7-8.4, p〈0.01), and AKI (OR 7.4, 95% CI 4.9 10.8, P- 0.01) were the independent predictors of mortality at 12-month follow-up. Conclusions: Early IABP insertion before primary PCI is associated with improved myocardial perfusion although DBT increases. IABP support before PCI does not confer a 12-month clinical benefit when used for STEMI with CS.展开更多
文摘BACKGROUND Cardiogenic shock(CS)is a life-threatening complication of acute myocardial infarction with high morbidity and mortality rates.Primary percutaneous coro-nary intervention(PCI)has been shown to improve outcomes in patients with CS.AIM To investigate the immediate mortality rates in patients with CS undergoing primary PCI and identify mortality predictors.METHODS We conducted a retrospective analysis of 305 patients with CS who underwent primary PCI at the National Institute of Cardiovascular Diseases,Karachi,Pak-istan,between January 2018 and December 2022.The primary outcome was immediate mortality,defined as mortality within index hospitalization.Uni-variate and multivariate logistic regression analyses were performed to identify predictors of immediate mortality.RESULTS In a sample of 305 patients with 72.8%male patients and a mean age of 58.1±11.8 years,the immediate mortality rate was found to be 54.8%(167).Multivariable analysis identified Killip class IV at presentation[odds ratio(OR):2.0;95%co-nfidence interval(CI):1.2-3.4;P=0.008],Multivessel disease(OR:3.5;95%CI:1.8-6.9;P<0.001),and high thrombus burden(OR:2.6;95%CI:1.4-4.9;P=0.003)as independent predictors of immediate mortality.CONCLUSION Immediate mortality rate in patients with CS undergoing primary PCI remains high despite advances in treatment strategies.Killip class IV at presentation,multivessel disease,and high thrombus burden(grade≥4)were identified as independent predictors of immediate mortality.These findings underscore the need for aggressive management and close monitoring of patients with CS undergoing primary PCI,particularly in those with these high-risk characteristics.

Prompt and accurate monitoring of cardiovascular and accompanying hemodynamic changes is crucial in achieving adequate management of the condition. Advances in technology has availed procedures such as pulse index continuous cardiac output (PiCCO), which can offer precise monitoring of cardiovascular functions and hemodynamic parameters.

AIM To assess whether use of the PiCCO system can improve clinical outcomes in elderly patients with AMI complicated by CS.METHODS Patients from emergency intensive care units (EICU) or coronary care units (CCU) were randomized to receive PiCCO monitoring or not. The APACHE II score, SOFA score, hs-TnI, NT-proBNP, PaO2/FiO2 ratio and lactate levels on day 1, 3 and 7 after treatment were compared. The infusion and urine volume at 0-24 h, 24-48 h and 48-72 h were recorded, as were the cardiac index (CI), extravascular lung water index (EVLWI), intrathoracic blood volume index (ITBVI) and global end diastolic volume index (GEDVI) at similar time intervals. RESULTS Sixty patients with AMI complicated by CS were included in the study. The PiCCO group had a significantly lower APACHE II score, SOFA score, hs-TnI and NT-proBNP levels on day 1, 3 and 7 after treatment. The infusion and urine volume during 0-24 h in the PiCCO group were significantly greater, and this group also showed significantly higher ADL scores. Furthermore, the PiCCO group spent lesser days on vasoactive agents, mechanical ventilation, and had a reduced length of stay in EICU/CCU. Additionally, the CI was significantly higher at 48 h and 72 h in the PiCCO group compared with that at 24 h, and the EVLWI, ITBVI and GEDVI were significantly decreased at 48 h and 72 h. CONCLUSION Applying the PiCCO system could improve the clinical outcomes of elderly patients with AMI complicated by CS.

Results: In-hospital mortality was 57% in patients with cardiogenic shock and 6% without shock (p = 0.005). Coronary levels of C-reactive protein (9.2 ± 6.9 vs. 1.7 ± 2.1 mg/L, p = 0.001), interleukin-6 (379 ± 137 vs. 24 ± 20 pg/mL, p = 0.003), and angiotensin II (19 ± 10 vs. 10 ± 6 pg/mL, p = 0.010) were extremely higher in patients with shock than without shock. Interleukin-6 and angiotensin II, but not C-reactive protein, revealed higher in coronary levels than in systemic levels. The presence of both myocardial blush grade el reperfusion (p = 0.012).

Toxic CS or CS related to deficiency carried a better outcome (mortality 5%). Post-myocardial infarction or post-cardiac arrest CS was associated with higher mortality. In the multivariate analyses, only SAPS II (OR 1.037;1.013 - 1.056;p = 0.0001), pulmonary hypertension (OR 4.8;1.3 - 17;p = 0.02), extra-renal replacement therapy (OR 2.9;1.3 - 6;p = 0.006), and dobutamine infusion (OR 0.44;0.2 - 0.96;p = 0.04) were significantly associated with in-hospital mortality. Conclusion: Dobutamine infusion was associated with a better outcome. Higher SAPS II, pulmonary hypertension, and extra-renal replacement therapy were associated with increased in-hospital mortality.
文摘BACKGROUND Critical care is rapidly evolving with significant innovations to decrease hospital stays and costs.To our knowledge,there is limited data on factors that affect the length of stay and hospital charges in cirrhotic patients who present with STelevation myocardial infarction-related cardiogenic shock(SRCS).AIM To identify the factors that increase inpatient mortality,length of stay,and total hospital charges in patients with liver cirrhosis(LC)compared to those without LC.METHODS This study includes all adults over 18 from the National Inpatient Sample 2017 database.The study consists of two groups of patients,including SRCS with LC and without LC.Inpatient mortality,length of stay,and total hospital charges are the primary outcomes between the two groups.We used STATA 16 to perform statistical analysis.The Pearson's chi-square test compares the categorical variables.Propensity-matched scoring with univariate and multivariate logistic regression generated the odds ratios for inpatient mortality,length of stay,and resource utilization.RESULTS This study includes a total of 35798453 weighted hospitalized patients from the 2017 National Inpatient Sample.The two groups are SRCS without LC(n=758809)and SRCS with LC(n=11920).The majority of patients were Caucasian in both groups(67%vs 72%).The mean number of patients insured with Medicare was lower in the LC group(60%vs 56%)compared to the other group,and those who had at least three or more comorbidities(53%vs 90%)were significantly higher in the LC group compared to the non-LC group.Inpatient mortality was also considerably higher in the LC group(28.7%vs 10.63%).Length of Stay(LOS)is longer in the LC group compared to the non-LC group(9 vs 5.6).Similarly,total hospital charges are higher in patients with LC($147407.80 vs$113069.10,P≤0.05).Inpatient mortality is lower in the early percutaneous coronary intervention(PCI)group(OR:0.79<0.11),however,it is not statistically significant.Both early Impella(OR:1.73<0.05)and early extracorporeal membrane oxygenation(ECMO)(OR:3.10 P<0.05)in the LC group were associated with increased mortality.Early PCI(-2.57 P<0.05)and Impella(-3.25 P<0.05)were also both associated with shorter LOS compared to those who did not.Early ECMO does not impact the LOS;however,it does increase total hospital charge(addition of$24717.85,P<0.05).CONCLUSION LC is associated with a significantly increased inpatient mortality,length of stay,and total hospital charges in patients who develop SRCS.Rural and Non-teaching hospitals have significantly increased odds of extended hospital stays and higher adjusted total hospital charges.The Association of LC with worse outcomes outlines the essential need to monitor these patients closely and treat them early on with higher acuity care.Patients with early PCI had both shorter LOS and reduced inpatient mortality,while early Impella was associated with increased mortality and shorter LOS.Early ECMO is associated with increased mortality and higher total hospital charges.This finding should affect the decision to follow through with interventional management in this cohort of patients as it is associated with poor outcomes and immense resource utilization.
文摘Introduction: Functional integrity of the hypothalamic pituitary axis is disrupted during severe infection or stress. The observed blunted response to corticotropin was interpreted as impaired secretory reserve of the adrenal glands and was termed as relative adrenocortical insufficiency. Aim of the work: To study the incidence of adrenal insufficiency in patients developed cardiogenic shock complicating ST segment elevation myocardial infarction. Materials and methods: Prospective cohort study was done for 90 patients admitted to Algalaa Hospital for whom basal cortisol and ACTH level were measured immediately before a standard-dose (250 μg) ACTH stimulation test (SST) and 60 minutes after SST Δmax is defined as the difference between the maximal value after the test and basal level of serum cortisol. Results: Baseline ACTH and total cortisol showed positive correlation to clinical severity scores (APACHE II and Lactate), LVEF as well as vasoactive inotrope score, all with significant p value (0.000). The higher baseline cortisol level was co-related to increased mortality (Baseline serum cortisol level was significantly lower in survivors (30.6 ± 6.1 vs 45.0 ± 16.3) p value: 0.000) while the better response of the adrenal gland to short stimulation test was co-related more to survival as detected by Δmax TC (difference of cortisol level before and after SST) (13.8 ±3.8 in survivors vs 8.5 ± 4.42 in non survivors) p value 0.000. Conclusion: A high baseline plasma TC was associated with increased mortality in patients with cardiogenic shock post acute myocardial infarction. Patients with lower baseline TC, but with a better adrenal response, appeared to have a survival benefit.
文摘A 51-year old female with a history of multiple sclerosis presented to the emergency department with hypotension and fatigue. She was found to be in cardiogenic shock. Her initial EKG was concerning for STEMI and her troponin was positive. She was eventually diagnosed with spontaneous coronary artery dissection. This case report discusses her presentation, management, and clinical course. We emphasize the need for emergency medicine physicians to be concerned for SCAD, especially in women with a history of fibromuscular dysplasia, connective tissue disorders, or peri-partum status.
文摘Background: Previous studies showed that patients with cardiogenic shock (CS) from ST-elevation acute myocardial infarction (STEMI) supported by intra-aortic balloon pump (IABP) before primary percutaneous coronary intervention (PCI) decreased the risk of in-hospital mortality than patients who received IABP after PCI. However, little evidence is available on the optimal order of IABP insertion and primary PCI. The aim of this study was to investigate the impact of the sequence of IABP support and PC1 and its association with major adverse cardiac and cerebrovascular events (MACCEs). Methods: Data were obtained from 218 consecutive patients with CS due to STEMI in Beijing Anzhen Hospital between 2008 and 2014% who were treated with 1ABP and PCI. The patients were divided into two groups: Group A in whom IABP received before PCI (n = 106) and Group B in whom IABP received after PCI (n = 112). We evaluated the myocardial perfusion using myocardial blush grade and resolution of ST-segment elevation. The primary endpoint was 12-month risk of MACCE. Results: Most baseline characteristics were similar in patients between the two groups. However, patients received 1ABP before PCI were associated with a delay of door-to-balloon time (DBT) and higher troponin I level (P 〈 0.05). However, myocardial perfusion was significantly improved in patients treated with IABP before PCI (P 〈 0.05). Overall, IABP support before PCI was not associated with significantly lower risk of MACCE (P 〉 0.05). In addition, risk of all-cause mortality, bleeding, and acute kidney injury (AKI) was similar between two groups (P 〉 0.05). Multivariate analysis showed that DBT (odds ratio [OR] 2.5, 95% confidence interval [C/] 1.1-4.8, P=0.04), lABP support after PCI (OR 5.7, 95% Cl 2.7-8.4, p〈0.01), and AKI (OR 7.4, 95% CI 4.9 10.8, P- 0.01) were the independent predictors of mortality at 12-month follow-up. Conclusions: Early IABP insertion before primary PCI is associated with improved myocardial perfusion although DBT increases. IABP support before PCI does not confer a 12-month clinical benefit when used for STEMI with CS.
