Abstract
Background and objectives Cardioembolic stroke (CES) appears to be a rare cause of stroke (4%-9%) in people living with HIV (PLWH) in sub-Saharan Africa (SSA). However, due to limited access to diagnostic resources, this may be an underestimate. It is also unclear which cardiac pathologies are the major contributors to CES in this region. We sought to determine the prevalence and aetiology of CES in PLWH and to determine whether there are any differences compared with HIV negative stroke patients. Methods This cross-sectional study recruited PLWH with new-onset stroke at a quaternary-level hospital in Johannesburg, South Africa, from 2014 to 2017, and compared them to age-matched and sex-matched HIV negative stroke patients. Comprehensive investigations were performed to determine the underlying stroke aetiology, including electrocardiography, echocardiography, CT angiography and cerebrospinal fluid examination. Results 85 PLWH with ischaemic stroke were recruited and compared with 109 HIV negative controls. CES was identified in 17/85 (20.0%) of PLWH. These patients had more severe strokes than PLWH with non-CES (National Institutes of Health Stroke Scale score 14.9±6.7 vs 11.7±5.4, p=0.04). Cardiomyopathy was the predominant cardiac pathology in PLWH (76.4% vs 45.5% in HIV negative, p=0.04) while valvulopathy was more common in HIV negative patients (42.4% vs 11.8% in PLWH, p=0.03). Arrhythmia (n=1) and ischaemic heart disease (n=1) were uncommon in PLWH. Conclusion CES is underdiagnosed in SSA and is more severe than non-CES. The identification of cardiomyopathy as the predominant underlying cardiac pathology may assist to target resources towards its detection using accessible cost-effective biomarkers.

Abstract
Heart failure is a commonly encountered clinical syndrome arising from a range of etiologic cardiovascular diseases and manifests in a phenotypic spectrum of varying degrees of systolic and diastolic ventricular dysfunction. Those affected by this life-limiting illness are subject to an array of burdensome symptoms, poor quality of life, prognostic uncertainty, and a relatively onerous and increasingly complex treatment regimen. This condition occurs in epidemic proportions worldwide, and given the demographic trend in societal ageing, the prevalence of heart failure is only likely to increase. The marked upturn in international migration has generated other demographic changes in recent years, and it is evident that we are living and working in ever more ethnically and culturally diverse communities. Professionals treating those with heart failure are now dealing with a much more culturally disparate clinical cohort. Given that the heart failure disease trajectory is unique to each individual, these clinicians need to ensure that their proposed treatment options and responses to the inevitable crises intrinsic to this condition are in keeping with the culturally determined values, preferences, and worldviews of these patients and their families. In this narrative review, we describe the importance of cultural awareness across a range of themes relevant to heart failure management and emphasize the centrality of cultural competence as the basis of appropriate care provision.

Abstract
Hypertension is the leading cause of cardiovascular disease in women, and sub-Saharan African (SSA) countries have some of the highest rates of hypertension in the world. Expanding knowledge of causes, management, and awareness of hypertension and its co-morbidities worldwide is an effective strategy to mitigate its harms, decrease morbidities and mortality, and improve individual quality of life. Hypertensive disorders of pregnancy (HDPs) are a particularly important subset of hypertension, as pregnancy is a major stress test of the cardiovascular system and can be the first instance in which cardiovascular disease is clinically apparent. In SSA, women experience a higher incidence of HDP compared with other African regions. However, the region has yet to adopt treatment and preventative strategies for HDP. This delay stems from insufficient awareness, lack of clinical screening for hypertension, and lack of prevention programs. In this brief literature review, we will address the long-term consequences of hypertension and HDP in women. We evaluate the effects of uncontrolled hypertension in SSA by including research on heart disease, stroke, kidney disease, peripheral arterial disease, and HDP. Limitations exist in the number of studies from SSA; therefore, we will use data from countries across the globe, comparing and contrasting approaches in similar and dissimilar populations. Our review highlights an urgent need to prioritize public health, clinical, and bench research to discover cost-effective preventative and treatment strategies that will improve the lives of women living with hypertension in SSA.

Abstract
BACKGROUND Heart failure is an important global health problem which is associated with high mortality. Uncontrolled heart failure leads to hospitalization and reduction in quality of life. Therefore, the study aimed to assess the treatment outcome such as improved, death, hospitalization, and self-discharges without improvement and associated factors in heart failure patients admitted to south western Ethiopian hospitals. METHODS We will use databases such as PubMed, Science Direct, HINARI, Scopus and Google Scholar. The final systematic review and meta-analysis will contain papers that fulfill the eligible criteria. A systematic data extraction check list will be used to extract the data, and STATA version 14 will be used for the analysis. Heterogeneity is evaluated using the I2 tests and the Cochrane Q test statistic. To examine publication bias, a funnel plot, Egger's weighted regression, and Begg's test are utilized. The sensitivity analysis and subgroup analysis will be done for studies having heterogeneity. The Joanna Briggs institute meta-analysis of statistics assessment and review instrument (JBI- MAStARI) will be used for quality assessment. DISCUSSION This protocol is expected to provide adequate evidence on the burden of poor heart failure treatment outcome that includes self-discharge, developing complication and finally leads to death in acute and chronic heart failure patients in Ethiopia. Furthermore, to enrich our estimation, we also intended to assess the associated factors of poor treatment outcome. Therefore, our review will call for government and non-government interventions in reducing the mortality associated with heart failure.

Abstract
STUDY OBJECTIVES Sleep-disordered breathing (SDB) is common in patients with congestive heart failure and has important implications regarding symptoms and prognosis. However, the burden of SDB on those with heart failure has not been well characterized in developing countries, including Mozambique in sub-Saharan Africa. Diagnosing SDB in individuals with congestive heart failure is important because treatment of SDB may improve outcomes. METHODS Between September 2014 and April 2017, patients hospitalized in a specialized cardiology unit in Maputo, Mozambique with decompensated congestive heart failure were recruited using convenience sampling. We determined the prevalence of SDB and associated risk factors. RESULTS A total of 165 patients were recruited, of which 145 had evaluable sleep study data. The overall prevalence of SDB in patients with decompensated congestive heart failure was 72%, and of these 46% had Cheyne-Stokes respirations. Male sex, higher body mass index, and lower left ventricular ejection fraction were all associated with a higher likelihood of SDB and more severe SDB. Cheyne-Stokes respirations were associated with male sex, lower ejection fraction, and larger left atrial size. CONCLUSIONS We conclude that in sub-Saharan Africa SDB is common in decompensated congestive heart failure and strongly predicted by demographic and echocardiographic parameters. This study highlights the need for the development of diagnostic tools and management strategies for patients with severe heart failure in resource-limited settings.

Abstract
Endomyocardial fibrosis (EMF) is an endemic idiopathic cardiomyopathy denoted by restricted and fibrous myocardium and endocardium. Apical fibrosis may cause thickening of the myocardium and extend from the ventricular apices through to the valves, thereby, restricting inflow. EMF is a critical condition that is predominant in the young population. However, it may also be associated with older individuals. Identified areas recorded with cases include the under-developed populations i.e. the tropics of Africa- Uganda, Mozambique; South Asia, and South America. Unlike in the preceded years, further studies are currently on focus to completely evaluate this medical condition. Additionally, this review encompasses the complications that arise from EMF as studied and reported from case studies, clinical trials, experiments and research including heart failure, atrioventricular valves regurgitations, arrhythmias, serous cavities'effusions, circulatory shock, stroke, myocardial ischemic syndromes, hepatic and end-organ dysfunctions. Complications like heart failure may be very fatal to its victims. Moreover, left ventricular thrombosis may probably impose systemic or cerebral thromboembolism, which would risk the probability of a stroke. All in all, suggestions in the management strategies that have proved effective and advances in cardiac transplantation and of recently proposed therapeutic targets equally take part of this review and may form a foundation to diminishing the remaining inch of EMF and its outcomes.

Abstract
Cardiac failure accounts for many deaths worldwide. Increasing experimental evidence suggests that exposure to chemicals such as bisphenol-S (BPS) and diethyl phthalate (DEP) exacerbate cardiac injuries. Morin is a flavonoid with reported cardioprotective activity. This study evaluated the modulation of pathways relevant to cardiac endothelial function in rats exposed to BPS and DEP mixture (Mix). Thirty male albino rats were distributed across five groups (n = 6): control received dimethyl sulfoxide (DMSO) as vehicle, Mix dissolved in DMSO, Mix + morin (25 mg/kg), Mix + morin (50 mg/kg), and morin (50 mg/kg). After 21 days of oral exposure at 1 ml/kg bodyweight of the Mix and treatment with morin, the animals were sacrificed, and their hearts were excised for biochemical, histological, immunohistochemical, and gene expression analyses. Exposure to the Mix caused a significant increase in oxidative stress indices (H2O2, malondialdehyde, DNA fragmentation, and advanced oxidation protein products). Also, arginase, phosphodiesterase 5', and the relative expression of TNF-α, interleukin-1β, Bax, androgen receptor, and vascular endothelial growth factor were markedly increased. In contrast, nitric oxide, reduced glutathione, interleukin-10 levels, superoxide dismutase, catalase, and glutathione peroxidase activities decreased significantly. Furthermore, p-NF-kB-p65 expression increased markedly in the Mix-exposed group. Morin treatment significantly reversed these perturbations in a dose-dependent manner in most instances. This study concludes that morin might offer a cardioprotective effect by enhancing the cardiac endothelial system and attenuating oxidative stress, inflammation, and apoptosis elicited by BPS and DEP co-exposure in male Wistar rats.

Abstract
In 2015, the United Nations set important targets to reduce premature cardiovascular disease (CVD) deaths by 33% by 2030. Africa disproportionately bears the brunt of CVD burden and has one of the highest risks of dying from non-communicable diseases (NCDs) worldwide. There is currently an epidemiological transition on the continent, where NCDs is projected to outpace communicable diseases within the current decade. Unchecked increases in CVD risk factors have contributed to the growing burden of three major CVDs-hypertension, cardiomyopathies, and atherosclerotic diseases- leading to devastating rates of stroke and heart failure. The highest age standardized disability-adjusted life years (DALYs) due to hypertensive heart disease (HHD) were recorded in Africa. The contributory causes of heart failure are changing-whilst HHD and cardiomyopathies still dominate, ischemic heart disease is rapidly becoming a significant contributor, whilst rheumatic heart disease (RHD) has shown a gradual decline. In a continent where health systems are traditionally geared toward addressing communicable diseases, several gaps exist to adequately meet the growing demand imposed by CVDs. Among these, high-quality research to inform interventions, underfunded health systems with high out-of-pocket costs, limited accessibility and affordability of essential medicines, CVD preventive services, and skill shortages. Overall, the African continent progress toward a third reduction in premature mortality come 2030 is lagging behind. More can be done in the arena of effective policy implementation for risk factor reduction and CVD prevention, increasing health financing and focusing on strengthening primary health care services for prevention and treatment of CVDs, whilst ensuring availability and affordability of quality medicines. Further, investing in systematic country data collection and research outputs will improve the accuracy of the burden of disease data and inform policy adoption on interventions. This review summarizes the current CVD burden, important gaps in cardiovascular medicine in Africa, and further highlights priority areas where efforts could be intensified in the next decade with potential to improve the current rate of progress toward achieving a 33% reduction in CVD mortality.

Abstract
BackgroundFirst described in Uganda over seven decades ago, Endomyocardial fibrosis (EMF) is a rare form of restrictive cardiomyopathy found in the tropics. EMF occurs mainly in two phenotypes; biventricular involvement and right ventricular (RV) form. Previously endemic in several countries, there are reports suggesting that the disease is on the decline.ObjectivesTo describe trends in annual incidence rates of newly diagnosed EMF cases at the Uganda Heart Institute (UHI).MethodsThis was a retrospective chart review of all newly diagnosed EMF cases at UHI from January 2007 to December 2020. Cases were divided into two groups A (2007–2013) and B (2014–2020).ResultsA total of 155 cases were diagnosed during the period (Group A, n = 124; Group B, n = 31). There were no significant differences between the two groups A and B regarding median age at diagnosis (14 vs. 12 years, p = 0.0940), gender (48.4% female vs. 35.5%, p = 0.1987), and EMF type (66.9% RV EMF vs. 71.0%, p = 0.6634), respectively. The presence of complications such as intracardiac thrombus (5.6 vs. 32.2%, p = 0.0002) and pericardial effusion (57.3% vs. 80.6, p = 0.0172) were more frequent in group B than A, respectively. Pulmonary hypertension (PHT) was predominantly seen in cases with biventricular EMF compared to those with RV EMF (26 vs. 3.8%, p = 0.0001). The number of new cases diagnosed per year remained largely stable in the period 2007–2011, ranging 14–21 per year, peaked in 2012 (26 new cases), and thereafter declined from 10 cases seen in 2013 to 1–5 cases seen per year in the period 2017–2020. Similarly, the annual incidence rates of new EMF diagnosis remained relatively stable in the period 2007–2012, ranging between 22.7 and 29.7 per 10,000 patients seen in the echo labs, and then dramatically declined after 2012 to range between 1.0 and 4.5 new cases per 10,000 patients in the period between 2017 and 2020.ConclusionThere has been a steady decline in the number of new cases of EMF seen at the UHI. However, there were no significant differences in the gender, age at diagnosis and EMF subtype of cases during the period under review. Complication rates were more frequent in the later cohort.

The prevalence, management, and thirty-day outcomes of symptomatic atrial fibrillation in a Tanzanian emergency department. Afr J Emerg Med 2021; 11:404-409. [PMID: 34703731 PMCID: PMC8524111 DOI: 10.1016/j.afjem.2021.07.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2021] [Revised: 06/10/2021] [Accepted: 07/27/2021] [Indexed: 11/16/2022] Open
Abstract
Introduction Data describing atrial fibrillation (AF) care in emergency centres (ECs) in sub-Saharan Africa is lacking. We sought to describe the prevalence and outcomes of AF in a Tanzanian EC. Methods In a prospective, observational study, adults presenting with chest pain or shortness of breath to a Tanzanian EC were enrolled from January through October 2019. Participants underwent electrocardiogram testing which were reviewed by two independent physician judges to determine presence of AF. Participants were asked about their medical history and medication use at enrollment, and a follow-up questionnaire was administered via telephone thirty days later to assess mortality, interim stroke, and medication use. Results Of 681 enrolled patients, 53 (7.8%) had AF. The mean age of participants with AF was 68.1, with a standard deviation (sd) of 21.1 years, and 23 of the 53 (43.4%) being male. On presentation, none of the participants found to have AF reported a previous history of AF. The median CHADS-VASC score among participants was 4 with an interquartile range (IQR) of 2-4. No participants were taking an anticoagulant at baseline. On index presentation, 49 (92.5%) participants with AF were hospitalised with 52 (98.1%) participants completing 30-day follow-up. 18 (34%) participants died, and 5 (9.6%) suffered a stroke. Of the surviving 31 participants with AF and a CHADS-VASC score ≥ 2, none were taking other anti-coagulants at 30 days. Compared to participants without AF, participants with AF were more likely to be hospitalised (OR 5.25, 95% CI 2.10-17.95, p < 0.001), more likely to die within thirty days (OR 1.93, 95% CI 1.03-3.50, p = 0.031), and more likely to suffer a stroke within thirty days (OR 5.91, 95% CI 1.76-17.28, p < 0.001). Discussion AF is common in a Tanzanian EC, with thirty-day mortality being high, but use of evidence-based therapies is rare. There is an opportunity to improve AF care and outcomes in Tanzania. In a Tanzanian emergency centre, atrial fibrillation was common but patient awareness of their condition was low Use of anticoagulants among patients with atrial fibrillation was rare both before and after hospital presentation Following hospital presentation, thirty-day mortality and stroke rates among patients with atrial fibrillation were high

Abstract
Heart failure remains a health challenge in Africa, associated with significant rates of hospitalization, morbidity and mortality. The current review aims to summarize the most recent data on the epidemiology, aetiology, risk factors and management of heart failure, comparing countries in North Africa and sub-Saharan Africa. There is a paucity of data on heart failure epidemiology, aetiology and management, and on the sociodemographic characteristics of African patients with heart failure. Heart failure prevalence has been evaluated among all medical admissions or admissions to cardiac units or emergency departments in a few hospital-based studies conducted in countries in North Africa and sub-Saharan Africa. Common causes of heart failure in Africa include ischaemic heart disease, hypertensive heart disease, dilated cardiomyopathy and valvular heart disease. The aetiology of heart failure differs between countries in North Africa and sub-Saharan Africa. Diagnosing heart failure proves challenging in Africa because of a lack of basic tools and the necessary human resources. The principal drugs used frequently for heart failure therapy are lacking in sub-Saharan Africa. The clinical profile of heart failure in sub-Saharan Africa differs from that in North African countries; this is related to aetiological factors, socioeconomic status and availability of diagnostic tools. There is an evident need to establish a large multicentre registry to evaluate the heart failure burden in almost all African countries, and to highlight the major cardiovascular risk factors and co-morbidities. The present review highlights the importance of this syndrome in Africa, and calls for improvements in its early diagnosis, treatment and, possibly, prevention.

Risk Factors and Prevalence of Dilated Cardiomyopathy in Sub-Saharan Africa: Protocol for a Systematic Review. JMIR Res Protoc 2021; 10:e18229. [PMID: 33475522 PMCID: PMC7862000 DOI: 10.2196/18229] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2020] [Revised: 10/15/2020] [Accepted: 10/20/2020] [Indexed: 12/16/2022] Open
Abstract
Background Cardiomyopathies, defined as diseases involving mainly the heart muscles, are linked to an estimated 5.9 of 100,000 deaths globally. In sub-Saharan Africa, cardiomyopathies constitute 21.4% of heart failure cases, with dilated cardiomyopathy (DCM) being the most common form. The etiology of DCM is heterogeneous and is broadly categorized as genetic or nongenetic, as well as a mixed disease in which genetics interact with intrinsic and environmental factors. Factors such as age, gender, family history, and ethnicity are nonmodifiable, whereas modifiable risk factors include poor nutrition, physical inactivity, and excessive alcohol consumption, among others. However, the relative contribution of the different risk factors to the etiology of DCM is not known in sub-Saharan Africa, and the prevalence of DCM among heart failure patients has not been systematically studied in the region. Objective The aim of this review is to synthesize available literature from sub-Saharan Africa on the prevalence of DCM among patients with heart failure, as well as the literature on factors associated with DCM. This paper outlines the protocol that will be followed to conduct the systematic review. Methods A limited search of the PubMed database will be performed to identify relevant keywords contained in the title, abstract, and subject descriptors using initial search terms “heart failure,” “cardiomyopathy,” and “sub-Saharan Africa.” These search terms and their synonyms will then be used in an extensive search in PubMed, and will address the first research question on prevalence. To address the second research question on risk factors, the terms “heart failure,” “cardiomyopathy,” and “cardiovascular risk factors” in “Sub-Saharan Africa” will be used, listing them one by one. Articles published from 2000 and in the English language will be included. Indexed articles in PubMed and Embase will be included, as well as the first 300 articles retrieved from a Google Scholar search. Collected data will be organized in Endnote and then uploaded to the Rayyan web app for systematic reviews. Two reviewers will independently select articles against the inclusion criteria. Discrepancies in reviewer selections will be resolved by an arbitrator. PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines for reporting systematic reviews will be applied. A map of sub-Saharan Africa with colors to show disease prevalence in each country will be included. For quantitative data, where possible, odds ratios (for categorical outcome data) or standardized mean differences (for continuous data) and their 95% CIs will be calculated. Results The primary outcomes will be the prevalence of DCM among patients with heart failure and cardiovascular risk factors associated with DCM in sub-Saharan Africa. The literature search will begin on January 1, 2021, and data analysis is expected to be completed by April 30, 2021. Conclusions This review will provide information on the current status of the prevalence and associated factors of DCM, and possibly identify gaps, including paucity of data or conflicting results that need to be addressed to improve our understanding of DCM in sub-Saharan Africa.

Abstract
Introduction Heart failure (HF) is a strong contributor to non-communicable diseases burden in sub-Saharan Africa (SSA). Few studies have addressed the pattern of HF in Burkina Faso. Methods We conducted a prospective cohort study in patients with acute HF in the Regional Hospital Center of Tenkodogo, eastern region of Burkina Faso. Patients were consecutively enrolled from 1st January 2015 to 31st December 2016 and followed up until June 2017. Primary outcome of interest was mortality. Results Overall 318 of 1805 cardiac cases presented with acute HF (17.62 %). Of the 298 patients included in the analysis process, 239 had de novo HF and 150 were male. The mean age was 58.56 ± 18.54 years. Eighty-eight patients presented with atrial fibrillation. The mean left ventricular ejection fraction (LVEF) was 38.20 ± 12.85 % with reduced ejection fraction (LVEF < 40%) accounting for 59.73% of the cases. Most of the study patients lived in rural areas. Hypertensive heart disease (50.34%) and idiopathic dilated cardiomyopathy (19.80%) were the leading causes of HF. Most patients received renin-angiotensin system blockers contrasting with a lower prescription rate of beta-blockers (99% versus 18.79% respectively). The incidence of all-cause mortality was 31 percent patients-years. Conclusion Heart failure is frequent in SSA, affecting patients at younger age. Predominantly of non-ischemic cause, commonly hypertensive, the disease is associated with high mortality.

Abstract
PURPOSE OF REVIEW This review aims at highlighting the need to better understand the pathogenesis and natural history of endomyocardial fibrosis when set against its changing endemicity and disease burden, improvements in diagnosis, and new options for clinical management. RECENT FINDINGS Progress in imaging diagnostic techniques and availability of new targets for drug and surgical treatment of heart failure are contributing to earlier diagnosis and may lead to improvement in patient survival. Endomyocardial fibrosis was first described in Uganda by Davies more than 70 years ago (1948). Despite its poor prognosis, the etiology of this neglected tropical restrictive cardiomyopathy still remains enigmatic nowadays. Our review reflects on the journey of scientific discovery and construction of the current guiding concepts on this mysterious and fascinating condition, bringing to light the contemporary knowledge acquired over these years. Here we describe novel tools for diagnosis, give an overview of the improvement in clinical management, and finally, suggest research themes that can help improve patient outcomes focusing (whenever possible) on novel players coming into action.

Abstract
PURPOSE OF REVIEW Acute heart failure (AHF) is a common emergency presentation in Sub-Saharan Africa (SSA). In the current review, we present the most recent data on the epidemiology of AHF in SSA and discuss recommended approaches to management in resource-limited settings, with a particular focus on primary and secondary facilities (e.g., health centers and district hospitals), where these patients often present. RECENT FINDINGS AHF in SSA is most often due to hypertension, cardiomyopathies, and rheumatic heart disease. The etiology of AHF may be different in rural as compared with urban settings. Diagnostic tools for AHF are often lacking in SSA, especially at the first-level facilities. Point-of-care ultrasound (POCUS) and biomarker tests, such as brain natriuretic peptide (BNP), offer promise in helping to mitigate diagnostic challenges. POCUS can also help distinguish among types of heart failure and prompt the correct treatment strategy. Many of the drugs and equipment commonly used to treat AHF in resource-rich settings are lacking in SSA. However, some adaptations of commonly available materials may provide temporary alternatives. The epidemiology of AHF in SSA differs from that of high-income settings. Management of AHF at the first-level facility in SSA is an important and understudied problem. Simplified diagnostic and treatment algorithms rooted in knowledge of the local epidemiology should be developed and tested as part of broader efforts to combat cardiovascular disease in SSA.
