Percutaneous Coronary Intervention in Acute Coronary Syndromes at the Mother-Child University Hospital Luxembourg in Bamako

Introduction: Acute coronary syndromes (ACS) are a diagnostic and therapeutic emergency. Objective: Studying the feasibility, difficulties and results of coronary angioplasty in acute coronary syndromes at the Luxembourg Mother-Child University Hospital in Bamako. Patients and Methods: Cross-sectional, descriptive study with prospective recruitment over 18 months from September 2020 to February 2022. All patients aged at least 18 years old admitted for SCA and having undergone PCI during the study period were included. Result: We collected 249 patients for SCA, of whom 160 underwent angioplasty, either an angioplasty/SCA ratio of 0.64. The average age of the patients was 59.54 ± 11.62 with extremes of 32 and 92 years. The age group of 45 to 65 years was the most representative. The predominance was male, sex ratio of 2.4. The main cardiovascular risk factors were high blood pressure (58.23%) and diabetes (45.78%). Persistent ST-segment elevation on the electrocardiogram was present in 71.48%. The treatment time was more than 12 hours after the first medical contact in 95.5%. The approach was radial in 96.5% of cases. Coronarography was pathological in 91.16% of our patients. The lesions were tri-truncular in 34.13% with the anterior inter ventricular as culprit artery in 72% of cases. The majority of patients (64%) had undergone angioplasty with implantation of an active stent. Angioplasty was performed successfully in 98% and per procedural mortality was 1.87%. Only 6.45% of ACS with ST elevation benefited from primary angioplasty. Conclusion: Percutaneous coronary intervention is performed routinely in our center with satisfactory results. Difficulties exist, related to the diagnostic delay of ACS and the high cost of angioplasty.

Cardio-Oncology: The Need of the Hour Subspeciality

There have been considerable advancements in cancer therapy in recent years. However, adverse effects often defeat the benefits, especially on the cardiovascular system. The effects of chemotherapeutic agents on the cardiovascular system can be directly on the heart by altering the coagulability state or by altering the hemodynamic system. Some drugs like Sunitinib and Bevacizumab show Heart Failure which is chemotherapy-induced. Other agents are notorious for showing QT prolongation like Vandetanib. Similarly, other agents with demonstrated cardiotoxicity would be molecular-targeted drugs (Trastuzumab and Pertuzumab) and cytostatic agents (Anthracycline antibiotics, Cyclophosphamide and 5-FU). These effects may present early or late, during or after the treatment. Most of the research has focused on the management and monitoring of patients for cancer who are under treatment, for example new biomarkers in the field of proteomics have been discovered for the diagnosis, treatment, and monitoring of patients. While the upgrades have been successful in reducing mortalities, with the advent of better treatment outcomes, the several adverse effects on the cardiac system cannot be dismissed. For instance, damage to the cardiomyocytes is most frequently associated with the treatment. The damage can further expedite LV failure, valvular dysfunction, conduction abnormalities, etc. Hence, a better management plan for patients with cancer would be one that not only caters to primary cancer treatment but also incorporates ventricular systolic function evaluation using echocardiography, electrocardiography, and cardiac biomarkers for the well-being of patients. Our article focuses on introducing an ideal cardio-oncology team along with the components required for setting up the team. This needs a multidisciplinary approach to reduce patients’ cardiovascular morbidity, during and after the interventions. With the growing population of patients undergoing cancer therapy, the risk of developing cardiovascular problems has further escalated. Hence, development of a cardio-oncology multidisciplinary team would be of utmost importance to not only improve patient care but also to improve quality of life.

Congenital Heart Disease Referred for Surgery: Analysis and Epidemiological Description in the Cardiology Department of CHU Ignace Deen

Introduction: Congenital heart disease includes all cardiac and vascular malformations. It accounts for approximately one third of all congenital malformations and is a public health problem, particularly in developing countries. The aim of this study was to analyze the epidemiological, clinical and paraclinical aspects of congenital heart disease. Methods: This was a retrospective descriptive and analytical study based on the records of 135 patients referred for surgery and followed up in the cardiology department of the Ignace Deen University Hospital, collected in November 2022. Results: Hospital prevalence was 5%. The mean age was 71 months, ranging from 1 month to 19 years. The age group over 24 months was the most represented (62%). The M/F sex ratio was 1.36. Urban origin was predominant (58%). The rate of children not attending school or dropping out was high (16%). Siblings with fewer than 4 children were the most common (88%). A heart murmur was the most frequent sign (78%), followed by cyanosis (36%) and heart failure (29%). The association between heart murmurs and CHD was proven with a p-value Conclusion: CHDs represent the main indication for paediatric cardiac surgery and follow-up (95%). We stress the importance of implementing a screening and management strategy for congenital heart disease.

Iron and Heart Failure: Current Concepts and Emerging Pharmacological Paradigms

Background: Emerging evidence has recognized that anemia and iron deficiency are recurrent comorbidities in chronic heart failure (HF) and several trials have established that iron administration improves myocardial asset and clinical scenario in HF. Purpose: Recent acquisitions suggest that iron deficiency represents a concrete bias in the pathogenetic mechanism of chronic HF, so we have investigated the putative role of the hepcidin/ferroportin axis in the cardiovascular setting to advocate novel pharmacological and clinical approaches. Methods: Here, after an excursus on iron metabolism, we first reviewed the ongoing studies on novel iron targeted compounds. Then, we summarize large clinical interventional studies conducted on patient suffering from iron deficiency and HF which have tested the effects of drugging iron regard QoL, hospitalizations and cardiovascular death. Results: Novel compounds such as hepcidin agonist (PTG 300), synthetic human hepcidin (LJPC-401) and anti FPN (Vamifeport) are ongoing in iron overloaded patients, while the hepcidin blocker (PRS-080) is under investigation in anemic patients. Noteworthy, novel insights could arise from the results of a Phase IV interventional study regarding the modification of hepcidin pathway in a large cohort of HF patients (n = 1992) by sodium glucose cotransporter 2 inhibitors. To date, several studies highlight the beneficial effect of iron administration in cardiovascular setting and latest evidences consider hepcidin level as a novel biomarker of cardiac injury and atherosclerosis. Conclusions: We advocate that data from ongoing studies will suggest novel iron targeted therapies for diagnosis, prognosis and therapy transferable in selected heart failed patients.

Long-Term Mortality of Children with Congenital Heart Disease Admitted to the Departmental University Hospital of Borgou/Alibori from 2011 to 2022

Background: Congenital heart disease is a public health issue due to its incidence and mortality rate. The aim of this study was to investigate the long-term mortality of children with congenital heart disease admitted to the Departmental University Hospital of Borgou/Alibori (CHUD-B/A) from 2011 to 2022. Methods: This descriptive longitudinal study with analytical aims covered 11 years (April 1, 2011 to December 31, 2022). It consisted of a review of the records of children under 15 years of age with echocardiographically confirmed congenital heart disease. This was followed by an interview with the parents to assess the children’s current condition. Data were entered using Kobocollect software and analyzed using R Studio 4.2.2. software. Results: A total of 143 complete files were retained. The median age at diagnosis was 14 months (IIQ: Q1 = 4;Q3 = 60) with a range of 2 days and 175 months, and the sex-ratio (M/F) was 0.96. Left-to-right shunts were the most frequent cardiopathy group (62.9%). Only 35 children (24.5%) benefited from restorative treatment. The mortality rate was 31.5%. Median survival under the maximum bias assumption was 114 months and 216 months under the assumption of minimum bias. Survival was significantly better in children with right-to-left shunts (p = 0.0049) under the assumption of minimum bias. The death risk factors were: age at diagnosis less than 12 months (aHR = 7.58;95% CI = 3.36 - 17.24;p Conclusion: The long-term mortality of congenital heart disease is high and favoured by the absence of restorative treatment. Local correction of congenital heart disease and medical follow-up will help to reduce this mortality.

Lower Extremity Arterial Disease in Patients with Type 2 Diabetes: Prevalence and Associated Factors at the Libreville University Hospital Center

Introduction: Lower extremity arterial disease in diabetic patients has distinct characteristics. Objectives: To study the hospital frequency of lower extremity arterial disease and identify associated factors in diabetic patients at the Libreville University Hospital Center (CHUL). Materials and Methods: This was a cross-sectional study conducted from July 1, 2023, to January 31, 2024, in the endocrinology department of the CHUL. All patients with type 2 diabetes over the age of 18 admitted to this department, regardless of the reason for hospitalization, who provided informed consent, were included. Socio-demographic data and cardiovascular risk factors were recorded. Personal and family cardiovascular history and functional symptoms were investigated. The physical examination included measuring blood pressure, heart rate, and the ankle-brachial index in all patients. Results: A total of 219 patients were included, of whom 75 had lower extremity arterial disease, representing a prevalence of 34.24%. It was compensated in 28 cases (37.33%) and decompensated in 39 patients (52%). In eight cases (10.67%), there was critical chronic ischemia. Cardiovascular risk factors associated with diabetes were physical inactivity (89.5%), hypertension (55.25%), overweight (49.77%), obesity (22.84%), and smoking (10.04%). In multivariate analysis, only hypertension (OR = 2.09;95% CI: 1.05 - 4.17;p = 0.035) and LDL cholesterol (OR = 2.75;95% CI: 1.10 - 6.85;p = 0.03) were significantly associated with lower extremity arterial disease in diabetics at the University Hospital of Libreville. Conclusion: Lower extremity arterial disease is common in diabetic patients at the University Hospital of Libreville. It is often asymptomatic, thus requiring systematic screening.[-rId11-]

Acute Coronary Syndrome of Young Subjects at the Luxembourg Mother-Child University Hospital in Bamako

Introduction: Acute coronary syndrome is often the first event of coronary disease of young subjects. Objective: To study sociodemographic, clinical, paraclinical, therapeutic and evolutionary aspects of acute coronary syndrome of young subjects. Patients and Methods: Descriptive cross-sectional study with prospective recruitment from October 01, 2020 to March 31, 2022. Were included all patients admitted for acute coronary syndrome whose age was less or equal to 45 years and who had undergone coronary angiography at the Mother-Child University Hospital on Luxembourg from Bamako. Results: During the study period, we collected 60 patient files out of 198. These 60 patient files met our inclusion criteria. Hospital frequency was 30.30%. Average age of patients was 40.43 ± 3.9 years. Sex ratio M/F was 5.3. Main cardiovascular risk factor was smoking tobacco (23.42%), followed by dyslipidemia (13.92%). Functional signs were dominated by angina 62% followed by dyspnea 25.3%. Persistent ST-segment elevation on electrocardiogram was present in 76.4%. Left ventricular systolic dysfunction was present in 26.5%. Time to first medical contact was more than 12 hours in 62.7% of cases. Radial approach was adopted in 94% of cases. Coronary angiography was pathological in 85% (n = 51) of cases. Lesions were single-vessel disease in 47.1% and culprit artery was anterior interventricular in 51% of cases. Dual anti-platelet aggregation was aspirin and ticagrelor in 91.8% of cases. Angioplasty was performed in all patients who had significant abnormalities at coronary angiography. In-hospital mortality was 3.9%. Conclusion: Acute coronary syndromes exist in young Africans with a male predominance. Main cardiovascular risk factor is smoking tobacco. Coronary lesions are single vessel disease in the majority of case. Most of patients meet medical team after 12 hours. Time to first medical contact is a main challenge in our country.

Identification and Validation of Vascular-Associated Biomarkers for the Prognosis and Potential Pathogenesis of Hypertension Using Comprehensive Bioinformatics Methods

Background: Hypertension, also known as increased blood pressure, is a phenomenon in which blood flows in blood vessels and causes persistently higher-than-normal pressure on the vessel wall. The identification of novel prognostic and pathogenesis biomarkers plays a key role in the management of hypertension. Methods: The GSE7483 and GSE75815 datasets from the gene expression omnibus (GEO) database were used to identify the genes associated with hypertension that were differentially expressed genes (DEGs). The functional role of the DEGs was elucidated by gene body (GO) enrichment analysis. In addition, we performed an immune infiltration assay and GSEA on the DEGs of hypertensive patients and verified the expression of novel DEGs in the blood of hypertensive patients by RT-qPCR. Results: A total of 267 DEGs were identified from the GEO database. GO analysis revealed that these genes were associated mainly with biological processes such as fibroblast proliferation, cell structural organization, extracellular matrix organization, vasculature development regulation, and angiogenesis. We identified five possible biomarkers, Ecm1, Sparc, Sphk1, Thbsl, and Mecp2, which correlate with vascular development and angiogenesis characteristic of hypertension by bioinformatics, and explored the clinical expression levels of these genes by RT-qPCR, and found that Sparc, Sphk1, and Thbs1 showed significant up-regulation, in agreement with the results of the bioinformatics analysis. Conclusion: Our study suggested that Sparc, Sphk1 and Thbs1 may be potential novel biomarkers for the diagnosis, treatment and prognosis of hypertension and that they are involved in the regulation of vascular development and angiogenesis in hypertension.

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.

Estimation of the Direct Cost of Management of Venous Thromboembolism in Three Reference Hospitals in the City of Yaoundé: A Retrospective Study over a Three-Year Period

Background: Venous thromboembolism (VTE) is a major public health problem due to its increasing frequency, mortality and management cost. This cost may require major financial efforts from patients, especially in developing countries like ours where less than 7% of the population has health insurance. This study aimed to estimate the direct cost of managing VTE in three reference hospitals in Yaoundé. Methods: This was a cross-sectional retrospective study over a three-year period (from January 1st 2018 to December 31 2020) carried out in the Cardiology departments of the Central and General Hospitals, and the Emergency Centre of the city of Yaoundé. All patients managed during the study period for deep vein thrombosis and pulmonary embolism confirmed by venous ultrasound coupled with Doppler and computed tomography pulmonary angiography respectively were included. For each patient, we collected sociodemographic and clinical data as well as data on the cost of consultation, hospital stay, workups and medications. These data were analysed using SPSS version 23.0. Results: A total of 92 patient’s records were analysed. The median age was 60 years [48 - 68] with a sex ratio of 0.53. The median direct cost of management of venous thromboembolism was 766,375 CFAF [536,455 - 1,029,745] or $1415 USD. Management of pulmonary embolism associated with deep vein thrombosis was more costly than isolated pulmonary embolism or deep vein thrombosis. Factors influencing the direct cost of management of venous thromboembolism were: hospital structure (p = 0.015), health insurance (p 0.001), type of pulmonary embolism (p = 0.021), and length of hospital stay (p = 0.001). Conclusion: Management of VTE is a major financial burden for our patients and this burden is influenced by the hospital structure, health insurance, type of pulmonary embolism and length of hospital stay.

Assessment of Oral Anticoagulation with Vitamin K Antagonists in Patients Living in a Low-Income Country of West Africa

Introduction: Despite the rise of direct oral anticoagulants (DOACs), vitamin K antagonists (VKA) remain the most widely used oral anticoagulants in developing countries. The aim of this study was to estimate the prevalence of good anticoagulation in patients treated with VKA in Lomé and describe associated factors. Methods: This was a cross-sectional study conducted from November 2019 to October 2020 in the cardiology departments of two University teaching hospitals in Lomé (CHU Sylvanus Olympio and CHU Campus), involving patients on VKA for ≥3 months, with a target international normalized ratio (INR) of 2.5 and a therapeutic margin between 2 and 3. The quality of anticoagulation was assessed by the time in therapeutic range (TTR) which was assessed by the Rosendaal method. Good anticoagulation was defined by a TTR > 70%. Results: A total of 344 patients were included (mean age = 58 ± 13.8 years, women = 56.1%). Indications for VKA treatment were represented by venous thromboembolic disease (43.3%), supraventricular arrhythmia (28.2%), severe left ventricular systolic dysfunction (19.8%) and pulmonary hypertension (8.7%). The average TTR was 47.6 ± 20.8%. The rate of good anticoagulation was 17.7%. Factors associated with good anticoagulation were the use of fluindione vs acenocoumarol (OR = 11.17;95% CI: 3.2 - 39.6;p = 0.0002), concomitant low-dose aspirin (OR 4.44;95% CI: 1.4 - 13.9;p = 0.01) and INR monitoring exclusively by the patient himself (OR = 4.92;95% CI: 1.5 - 16.3;p = 0.008). The rate of thromboembolic and hemorrhagic complications was each 2.6% and was not correlated with the quality of anticoagulation. Quality of anticoagulation by VKAs was poor in our practice. Factors associated with good anticoagulation were the use of fluindione vs acenocoumarol, concomitant low-dose aspirin and monitoring of INR exclusively by the patient himself. Conclusion: The quality of oral anticoagulation by VKAs could be improved in our practice by the creation of anticoagulation clinics for better therapeutic education of patients and efficient management of VKA dose, and the use of prescription assistance software.

Implications of Elevated Serum Cortisol in the Onset of Postoperative Delirium Following Off-Pump Coronary Artery Bypass Grafting: Insights from a Bangladesh-Based Single Center Experience

Background: Following coronary artery bypass grafting (CABG), delirium emerges as a prevalent complication. This study aimed to assess the correlation between elevated serum cortisol levels and the occurrence of postoperative delirium subsequent to off-pump CABG. Methods: Conducted in the Department of Cardiac Surgery at BSMMU from October 2020 to September 2022, this comparative cross-sectional study included a total of 44 participants. Subjects, meeting specific criteria, were purposefully assigned to two groups based on off-pump CABG. Group A (n = 22) consisted of patients with normal serum cortisol levels, while Group B (n = 22) comprised individuals with high serum cortisol levels on the first postoperative day. Delirium onset was assessed at the bedside in the ICU on the 1st, 2nd, 3rd, 4th, and 5th postoperative days using standard tools, namely the Richmond Agitation Sedation score (RASS) and The Confusion Assessment Method (CAM-ICU). Data were collected based on the presence or absence of delirium. Statistical analysis utilized SPSS version 26.0, employing an independent Student’s t-test for continuous data and chi-square and Fischer’s exact test for categorical data. A p-value ≤ 0.05 was considered statistically significant. Results: Group-A had a mean age of 54.50 ± 17.97, and Group-B had a mean age of 55.22 ± 15.45, both with a male predominance (81.81% and 86.36% respectively). The mean serum cortisol level was significantly higher in Group B (829.71 ± vs. 389.98 ± 68.77). Postoperative delirium occurred in 27.3% of Group B patients, statistically significant compared to the 4.5% in Group A. However, patients in Group B who developed delirium experienced significantly longer postoperative ICU and hospital stays (79.29 ± 12.27 vs. 11.44 ± 2.85, p ≤ 0.05). There was one mortality in Group B, which was statistically not significant. Conclusion: This study observed a significant association between elevated serum cortisol levels in the postoperative period and the occurrence of postoperative delirium after off-pump coronary artery bypass grafting.

Epidemiological, Clinical and Coronary Angiography Aspects of Acute Coronary Syndrome in the Cardiology Department of the Hospital Mother-Child “Le Luxembourg”Mali

Introduction: Cardiac catheterisation plays a fundamental role in the management of acute coronary syndrome. These explorations require heavy, complex and costly equipment and a large team of doctors, nurses and technicians with highly specialized training. Aims: To describe epidemiological, clinical and coronary angiography aspects of patients with acute coronary syndrome. Patients and Methods: Descriptive study from September 2019 to December 2023 in the Cardiology Department of the Hôpital Mère-Enfant of Bamako. Inclusion criteria were patients admitted for coronary angiography with the diagnosis of acute coronary syndrome. Results: During the study period, 1253 patients underwent coronary angiography, 596 of whom had acute coronary syndrome as an indication, representing a hospital frequency of 47%. Sex-ratio was 2.10. Mean age of patients was 58.5 ± 11.39 years. ST elevation acute coronary syndrome was the most common indication with 63.92% of cases. High blood pressure was the main cardiovascular risk factor with 58.7% of cases, and radial access approach was used in 98% of cases. Coronary angiography was pathological in 91.70% of cases (n = 548). Patients with lesions of anterior interventricular artery were 73.73% of cases. Tritruncal lesions accounted for 40.63% of cases. Conclusion: ST elevation acute coronary syndrome is the most frequent manifestation of acute coronary syndrome. Anterior interventricular artery is most often the culprit lesion for our patients.

Functional Capacity of Patients with Venous Thromboembolic Disease Six to Twelve Months after Treatment

Background: Venous thromboembolism (VTE) is among the leading causes of hospital-related disability-adjusted life years lost. We aimed to determine the prevalence and determinants of functional capacity impairment six to twelve months after an acute VTE event. Methods: This was a cross-sectional study conducted between January and April 2021 in two referral hospitals of Yaoundé, including consenting adult patients admitted to these hospitals six to twelve months ago for VTE. We excluded dead patients and those with any comorbidity or symptoms limiting physical activity. The functional outcome was assessed with the six-minute walk test. Functional capacity impairment was defined as walking distance lower than the expected value. Results: We included 27 cases in this study with a mean age of 53.2 ± 14.4 years. The prevalence of functional capacity impairment was 29.6% (95% CI: 14.8 - 48.1). Factors associated with poor functional outcome were obesity (OR: 59.5;95% CI: 4.6 - 767.2;p - 207.4;p = 0.017), massive PE (OR: 30;95% CI: 2.5 - 354;p = 0.004), and poor adherence to treatment (OR: 30.3;95% CI: 2.5 - 333.3;p = 0.004). Conclusion: Functional capacity impairment is common in the medium-term after VTE and factors associated with this poor outcome are obesity, the severity of the VTE, and poor adherence to treatment.

Totally Occluded Coarctation of the Aorta in a Young Adult

We report the case of a 20-year-old female patient presenting with a totally occluded coarctation of the aorta. The patient was admitted for the evaluation of resistant grade III high blood pressure. The physical examination revealed a blood pressure gradient between the upper and lower limbs, absent femoral pulses, a diffuse continuous murmur over the chest, and hyperpulsatility of the carotid arteries and sternal notch. A transthoracic echocardiography outlined a narrowing in the caliber of the isthmic aorta without acceleration of flow or gradient. Thoracic CT angiography revealed a complete aortic coarctation with interruption of continuity between segment 3 and the descending aorta.

Mechanical Complications after Myocardial Infarction: A Comprehensive Review

Mechanical complications of myocardial infarction are potentially fatal events that can occur after an acute myocardial infarction. While the introduction of primary percutaneous reperfusion and fibrinolysis has reduced the incidence of these complications to less than 1%. These complications pose significant hemodynamic consequences and necessitate prompt diagnosis. Echocardiography, cardiac magnetic resonance imaging, and computed tomography are valuable tools for establishing an accurate and expedited diagnosis. Consequently, it is imperative to conduct further scientific research to enhance hemodynamic stabilization techniques such as intra-aortic balloon counterpulsation and extracorporeal membrane oxygenation, in addition to exploring new surgical procedures that can reduce mortality resulting from mechanical complications. This article aims to provide a comprehensive review of mechanical complications following myocardial infarction and their correlation with multi-imaging, facilitating a better understanding of these complications.

Epidemiological, Clinical, Therapeutic, and Evolutionary Aspects of Heart Failure in the Medical Department at Gao Regional Hospital

Introduction: Heart failure is a major public health pandemic, particularly in Africa, where its prevalence continues to increase. In northern Mali, few data exist, hence the interest of this study with the objective of studying the epidemiological, clinical and therapeutic and evolutionary aspects of Heart failure at the regional hospital of Gao. Patients and Methods: This was a cross-sectional, descriptive study that took place from July 2022 to June 2023 in the medical department at Gao Hospital. Results: The hospital prevalence of heart failure was 44.1%. The mean age was 47.30 ± 20 years (range: 16-88). Hypertension was the most common with 46.1%, followed by a sedentary lifestyle, and diabetes with 18.2% and 8.3% respectively;NYHA stage III-IV dyspnea was found in 83.9%. Reduced EF heart failure was present in 110 patients (76.9%), seventeen cases with moderately reduced EF (11.9%) and sixteen patients had preserved EF (11.2%). Global heart failure was the dominant (91.6%). The main etiologies of heart failure were dominated by hypertensive heart disease in 46 patients (32.2%), followed by postpartum cardiomyopathy with 43 cases (30.1%), primary dilated cardiomyopathy in 18 patients (12.6%), ischemic heart disease in 16 patients with 11.2%. Seven cases of valvular heart disease, or 4.9%. The evolution was favorable under treatment in 104 patients or 72.7%. In-hospital mortality was 14.7%. Conclusion: Heart failure is a common condition in sub-Saharan Africa, particularly in our country.

The Importance of Setting Treatment Goals for Cardiovascular Diseases

Background: Guidelines are issued by most major organizations that focus on a specific disease entity. Guidelines should be a significant help to the practicing physician who may not be up-to-date with the recent medical literature. Unfortunately, when conflicting guidelines for a specific disease are published, confusion results. Purpose: This article provides a suggested guideline outcome measure that would benefit the physician and patient. Methods: A review of 19 different guidelines for cardiovascular disease treatment is one example of the lack of specific outcomes that currently exist. The basic problem with most guidelines is that they do not state the expected end result (i.e., the benefit to the patient) if that guideline is followed. When guidelines use cardiovascular disease risk factors to dictate therapy, the end benefit is never stated so that the patient can make an appropriate choice of which (if any) guideline to follow. Results: A good example is guidelines published by the American Heart Association for reducing cardiovascular disease. These guidelines are risk factor based and only indicate that cardiovascular disease would be reduced if followed. No specific percentage in the reduction of the incidence of disease is given. In contrast, when elimination of the disease is the stated goal of the guideline, the end result is clear. To date, this goal has been stated by only one organization devoted to eliminating cardiovascular disease. Conclusion: Guidelines need to be written to provide the physician and the patient with a specific end point that is expected when the guideline is followed. Patient acceptance and compliance will be much improved if the patient knows the risk/benefit of following the guideline’s recommendations.

Screening, Treatment and Control of High Blood Pressure on Five Sites in Mali

Introduction: High blood pressure is defined as blood pressure greater than or equal to 140 mm Hg for systolic and or 90 mm Hg for diastolic. It constitutes a major public health problem, the leading chronic disease in the world. The objective was to determine the prevalence, treatment rate and control of hypertension. Methods: This was a cross-sectional and descriptive study which took place over a period of 6 months in a hospital environment and in the general population. Results: Of the 1000 participants, 637 had hypertension, giving a prevalence of 63.70% with a female predominance. Thirty-three percent (33%) were unaware of their high blood pressure. The age group 60 and more was the most represented (44%). A proportion of 33 and 23.20 were overweight and obese participants, respectively. Male subjects were more overweight than female, unlike obesity which was more common among female subjects. Sixty-two percent (62%) of hypertensives were treated, of whom 44% were non-compliant. The excessively high cost and consumption of medications as needed were the main factors in therapeutic non-compliance. Twenty-two percent (22%) of all hypertensive patients and 35% of treated hypertensive patients were controlled. Women were more treated but less observant and less controlled than men. Therapeutic coverage and combination therapy rates were lower in rural areas. Hypertensives who had a high level of education were better treated and controlled than those who had no level. Conclusion: High blood pressure remains a real public health problem in Mali. It is more common in people aged 60 and over and in females. One in three hypertensives were unaware of their hypertension. The majority received antihypertensive treatments, but only a minority of them had their hypertension controlled.

Interest of Cardiac Rehabilitation in Patients with Heart Disease in a Cardiology Department in Senegal

Cardiac rehabilitation helps improve the prognosis and quality of life for patients with heart disease. To show its interest in the African context, in the management of heart disease, a prospective study was carried out. Its objective was to evaluate the effects of physical rehabilitation on cardiac function. Methods: Patients were evaluated at the beginning and at the end of cardiovascular rehabilitation by cardiovascular, biological, and echocardiographic parameters including the size of the heart chambers, the kinetics of the walls, and the systolic function of the ventricles. Results: The study involved 12 patients, 67% of whom were men. After cardiac rehabilitation, the mean hemodynamic constants had not been significantly modified. However, a significant decrease in Total-Cholesterol, LDL-Cholesterol and triglyceride levels was noted. Mean fasting blood sugar decreased from 1.25 ± 0.48 g/L to 0.92 ± 0.18 g/L and glycated hemoglobin from 7.72% ± 0.01% to 6.45% ± 0.008%. The echocardiographic parameters studied showed an improvement in the dilation of the heart chambers in 8.33% of the patients, the normalization of the ejection fraction of the left ventricle in 16% patients, the improvement of the kinetic disorders in 16% of patients and recovery of right ventricular systolic function in all patients. Conclusion: Cardiac rehabilitation as a secondary preventive measure for cardiovascular disease has contributed significantly to improving the clinico-biological parameters of the disease.
