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.

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.

Peripartum Cardiomyopathy: Epidemiological, Clinical, Para-Clinical and Therapeutic Aspects at the Tombouctou Hospital

Introduction: Peripartum cardiomyopathy (PPCM) is a heart failure whose etiology is still unknown. The aim of work was to study peripartum cardiomyopathy in its epidemiological, clinical, paraclinical and therapeutic aspects at the Tombouctou hospital. Methods: This is a descriptive cross-sectional study carried out in the Medicine Department of the Timbuktu hospital from January 1 to December 31, 2019. It concerned patients who presented heart failure between the 8th month of pregnancy and the first 5 months postpartum. Results: During the study,23 patients were collected. Average age of the patients was 23.50 ± 3.50 years with extremes of 16 and 34 years. Incidence of Peripartum cardiomyopathy (PPCM) was 1/345 pregnancies. Average parity was 3.20 with extremes of 1 and 8. Symptoms appeared at postpartum with 87% of cases. A significant delay in diagnosis was observed. Global heart failure was the mode of decompensation with 70%. Electrocardiographic signs were mainly sinus tachycardia (87%) and left ventricular hypertrophy (83%). Cardiac ultrasound showed in all cases dilated cardiomyopathy and it was associated with thrombus in left ventricle cavity for three cases. Left ventricular ejection fraction was severely impaired in 70% of cases. Pulmonary hypertension was significant in 52%. Most commonly drugs we used in our series at acute stage were duretics: furosemide 100% and spironolactone 70% (100% and 70%) and ACE inhibitors (90%). Beta-blockers (bisoprolol and carvedilol) were used in 15 patients. Bromocriptine (prolactin inhibitor) was used for 2 patients. Conclusion: Peripartum cardiomyopathy is a serious cardiac complication of pregnancy of unknown cause, common in the African population.

Congenital Heart Disease: Epidemiological and Echocardiography Aspects in the Cardiology Department of Tombouctou Hospital, Mali

Congenital heart diseases are abnormalities of heart that occur during intrauterine life. Our work aimed to study the epidemiological and echocardiographic aspects of congenital heart disease with Cardiology Department of the Tombouctou hospital. This was a descriptive cross-sectional study from November 2018 to December 31, 2019 on Doppler echocardiography reports from patients admitted to the Cardiology department. The probes used were 3.5 and 5 MHz on an Esaote Mylab40 device. The inclusion criteria concerned patients of both sexes under the age of 16, hospitalized or followed in the cardiology department for cardiac symptoms and having benefited from a cardiac Doppler ultrasound. Results: During the study period, 370 echocardiographic examinations were performed and revealed 20 cases of congenital heart disease with a prevalence of 5.45%. The female sex was the majority 13/7 cases which makes a sex ratio of 0.54. Heart murmurs were the main reason for requesting cardiac Doppler ultrasound with the 13 out of 20 cases of congenital heart disease (65%). Interventricular communication was represented by 15 cases (75%). Congenital heart disease is a reality in Africa. Its frequency and reported series are underestimated due to the inaccessibility of Doppler echocardiography.
