AimsTo provide comprehensive information on the access and use of cardiac implantable electronic devices (CIED) and catheter ablation procedures in Africa.Methods and resultsThe Pan-African Society of Cardiology (PASCAR) collected data on invasive management of cardiac arrhythmias from 2011 to 2016 from 31 African countries. A specific template was completed by physicians, and additional information obtained from industry. Information on health care systems, demographics, economics, procedure rates, and specific training programs was collected. Considerable heterogeneity in the access to arrhythmia care was observed across Africa. Eight of the 31 countries surveyed (26%) did not perform pacemaker implantations. The median pacemaker implantation rate was 2.66 per million population per country (range: 0.14–233 per million population). Implantable cardioverter-defibrillator and cardiac resynchronization therapy were performed in 12/31 (39%) and 15/31 (48%) countries respectively, mostly by visiting teams. Electrophysiological studies, including complex catheter ablations were performed in all countries from Maghreb, but only one sub-Saharan African country (South Africa). Marked variation in cost (up to 1000-fold) was observed across countries with an inverse correlation between implant rates and the procedure fees standardized to the gross domestic product per capita. Lack of economic resources and facilities, high cost of procedures, deficiency of trained physicians, and non-existent fellowship programs were the main drivers of under-utilization of interventional cardiac arrhythmia care.ConclusionThere is limited access to CIED and ablation procedures in Africa. A quarter of countries did not have pacemaker implantation services, and catheter ablations were only available in one country in sub-Saharan Africa.
The 143 low- and middle-income countries (LMICs) of the world constitute 80% of the world’s population or roughly 5.86 billion people with much variation in geography, culture, literacy, financial resources, access to health care, insurance penetration, and healthcare regulation. Unfortunately, their burden of cardiovascular disease in general and acute ST-segment–elevation myocardial infarction (STEMI) in particular is increasing at an unprecedented rate. Compounding the problem, outcomes remain suboptimal because of a lack of awareness and a severe paucity of resources. Guideline-based treatment has dramatically improved the outcomes of STEMI in high-income countries. However, no such focused recommendations exist for LMICs, and the unique challenges in LMICs make directly implementing Western guidelines unfeasible. Thus, structured solutions tailored to their individual, local needs, and resources are a vital need. With this in mind, a multicountry collaboration of investigators interested in LMIC STEMI care have tried to create a consensus document that extracts transferable elements from Western guidelines and couples them with local realities gathered from expert experience. It outlines general operating principles for LMICs focused best practices and is intended to create the broad outlines of implementable, resource-appropriate paradigms for management of STEMI in LMICs. Although this document is focused primarily on governments and organizations involved with improvement in STEMI care in LMICs, it also provides some specific targeted information for the frontline clinicians to allow standardized care pathways and improved outcomes.
Background: Coronary artery disease and its acute presentation are being increasingly recognised and treated in sub-Saharan Africa. It is just over a decade since the introduction of interventional cardiology for coronary artery disease in Kenya. Local and regional data, and indeed data from sub-Saharan Africa on long-term outcomes of acute coronary syndromes (ACS) are lacking. was carried out to obtain data on patient characteristics, treatment and in-patient outcomes. Patient interviews and a review of clinic records were conducted to determine long-term mortality rates and major adverse cardiovascular events. Results: A total of 230 patients were included in the analysis; 101 had a diagnosis of ST-segment myocardial infarction (STEMI), 93 suffered a non-ST-segment myocardial infarction (NSTEMI), and 36 had unstable angina (UA). The mean age was 60.5 years with 81.7% being male. Delayed presentation (more than six hours after symptom onset) was common, accounting for 66.1% of patients. Coronary angiography was performed in 85.2% of the patients. In-hospital mortality rate was 7.8% [14.9% for STEMI and 2.3% for non-ST-segment ACS (NSTE-ACS, consisting of NSTEMI and UA)], and the mortality rates at 30 days and one year were 7.8 and 13.9%, respectively. Heart failure occurred in 40.4% of STEMI and 16.3% of NSTE-ACS patients. Re-admission rate due to recurrent myocardial infarction, stroke or bleeding at one year was 6.6%. Conclusion: In our series, the in-hospital, 30-day and one-year mortality rates following ACS remain high, particularly for STEMI patients. Delayed presentation to hospital following symptom onset is a major concern.
Background: Pulmonary hypertension is poorly studied in Africa. The long-term survival rates and prognostic factors associated with mortality in patients with moderate to severe pulmonary hypertension (PH) in Africa are not well described. Objectives:To determine the causes of moderate to severe PH in patients seen in contemporary hospital settings, determine the patients' one-year survival and the factors associated with mortality following standard care. Methods: A retrospective review of patients diagnosed with moderate to severe PH at Aga Khan University Hospital (AKUHN) from August 2014 to July 2017 was carried out. Clinical and outcome data were collected from medical records and the hospital mortality database. Telephone interviews were conducted for patients who died outside the hospital. Survival analysis was done using Kaplan-Meier, and log-rank tests were used to assess differences between subgroups. Cox regression modelling with multivariable adjustment was used to identify factors associated with all-cause mortality. Results: A total of 659 patients with moderate to severe PH were enrolled. Median follow-up time was 626 days. The survival rates of the patients at 1 and 2 years were 73.8% and 65.9%, respectively. The following variables were significantly associated with mortality: diabetes mellitus [adjusted HR 1.52, 95% CI (1.14-2.01)], WHO functional class III/IV [adjusted HR 3.49, 95% CI (2.46-4.95)], atrial fibrillation [adjusted HR 1.53, 95% CI (1.08-2.17)], severe PH [adjusted HR 1.72, 95% CI (1.30-2.27)], right ventricular dysfunction [adjusted HR 2.42, 95% CI (1.76-3.32)] and left ventricular dysfunction [adjusted HR 1.91, 95% CI (1.36-2.69)].Obesity [adjusted HR 0.68, 95% CI (0.50-0.93)] was associated with improved survival. Conclusion: Pulmonary hypertension is associated with poor long-term outcomes in African patients. Identification of prognostic factors associated with high-risk patients will assist in patient management and potentially improved outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
