Background Coronary artery disease was hitherto a rarity in Africa. Acute coronary syndrome (ACS) accounts for coronary artery disease-related morbidity and mortality. Reports on ACS in Africa are ...few. Methods and Results We enrolled 1072 indigenous Nigerian people 59.2±12.4 years old (men, 66.8%) with ACS in an observational multicentered national registry (2013-2018). Outcome measures included incidence, intervention times, reperfusion rates, and 1-year mortality. The incidence of ACS was 59.1 people per 100 000 hospitalized adults per year, and comprised ST-segment-elevation myocardial infarction (48.7%), non-ST-segment-elevation myocardial infarction (24.5%), and unstable angina (26.8%). ACS frequency peaked 10 years earlier in men than women. Patients were predominantly from urban settings (87.3%). Median time from onset of symptoms to first medical contact (patients with ST-segment-elevation myocardial infarction) was 6 hours (interquartile range, 20.1 hours), and only 11.9% presented within a 12-hour time window. Traditional risk factors of coronary artery disease were observed. The coronary angiography rate was 42.4%. Reperfusion therapies included thrombolysis (17.1%), percutaneous coronary intervention (28.6%), and coronary artery bypass graft (11.2%). Guideline-based pharmacotherapy was adequate. Major adverse cardiac events were 30.8%, and in-hospital mortality was 8.1%. Mortality rates at 30 days, 3 months, 6 months, and 1 year were 8.7%, 9.9%, 10.9%, and 13.3%, respectively. Predictors of mortality included resuscitated cardiac arrest (odds ratio OR, 50.0; 95% CI, 0.010-0.081), nonreperfusion (OR, 34.5; 95% CI, 0.004-0.221), pulmonary edema (OR, 11.1; 95% CI, 0.020-0.363), left ventricular diastolic dysfunction (OR, 4.1; 95% CI, 0.091-0.570), and left ventricular systolic dysfunction (OR, 2.1; 95% CI, 1.302-3.367). Conclusions ACS burden is rising in Nigeria, and patients are relatively young and from an urban setting. The system of care is evolving and is characterized by lack of capacity and low patient eligibility for reperfusion. We recommend preventive strategies and health care infrastructure-appropriate management guidelines.
Background: There is no large-scale study that has shown the effi cacy of single pill combination (SPC) antihypertensive medications in black African population. We therefore evaluated the blood ...pressure (BP) lowering effi cacy and the tolerability of Perindopril plus Amlodipine SPC in black African patients.Methods: It was a multi-centre, prospective, observational programme among hypertensive patients using different doses of Perindopril and Amlodipine. Primary endpoint was assessed as the change in mean sitting systolic and diastolic BPs from baseline to 3 months.Results: 937 patients (55.7% female) were analysed, and the mean age was 56.4 ± 12.7 years. Systolic and diastolic BPs were signifi cantly reduced by 17.3/ 9.4mmHg, 21.1/10.8mmHg mmHg and 24.6/12.7mmHg at 4, 8 and 12 weeks respectively compared to baseline value (p<0.0001). Dry cough was seen in 0.64% and angioedema 0.1% of the patients.Conclusions: Perindopril plus Amlodipine SPC provided clinically meaningful BP reductions and is well tolerated in a black African population.
Acute rheumatic fever (ARF) and rheumatic heart disease (RHD) remain major causes of heart failure, stroke and death among African women and children, despite being preventable and imminently ...treatable. From 21 to 22 February 2015, the Social Cluster of the Africa Union Commission (AUC) hosted a consultation with RHD experts convened by the Pan-African Society of Cardiology (PASCAR) in Addis Ababa, Ethiopia, to develop a 'roadmap' of key actions that need to be taken by governments to eliminate ARF and eradicate RHD in Africa. Seven priority areas for action were adopted: (1) create prospective disease registers at sentinel sites in affected countries to measure disease burden and track progress towards the reduction of mortality by 25% by the year 2025, (2) ensure an adequate supply of high-quality benzathine penicillin for the primary and secondary prevention of ARF/RHD, (3) improve access to reproductive health services for women with RHD and other non-communicable diseases (NCD), (4) decentralise technical expertise and technology for diagnosing and managing ARF and RHD (including ultrasound of the heart), (5) establish national and regional centres of excellence for essential cardiac surgery for the treatment of affected patients and training of cardiovascular practitioners of the future, (6) initiate national multi-sectoral RHD programmes within NCD control programmes of affected countries, and (7) foster international partnerships with multinational organsations for resource mobilisation, monitoring and evaluation of the programme to end RHD in Africa. This Addis Ababa communiqué has since been endorsed by African Union heads of state, and plans are underway to implement the roadmap in order to end ARF and RHD in Africa in our lifetime.
