Atrial Fibrillation in Africa—An Under-Reported and Unrecognized Risk Factor for Stroke: A Systematic Review

Publication date: September 2019Source: Global Heart, Volume 14, Issue 3Author(s): Maartje S. Jacobs, Marinus van Hulst, Abiodun M. Adeoye, Robert G. Tieleman, Maarten J. Postma, Mayowa O. OwolabiAbstractOver three-quarters of deaths from cardiovascular disease and diabetes occur in low- and middle-income countries, which include many African countries. Global studies showed that the prevalence of the cardiac arrhythmia atrial fibrillation (AF) appeared to be lower in Africa. A systematic search of PubMed and African Journals Online was conducted to determine the prevalence of AF and associated stroke risk factors in Africa and to quantify the need for screening. The publications search yielded a total of 840 articles of which 41 were included. AF was often not identified as the disease of primary interest with its own risks. Data on prevalence in the general population was scarce. The prevalence of stroke risk factors showed a large variation between studies, as well as within clustered subpopulations. AF in Africa is under-reported in published reports. The study types and populations are highly heterogeneous, making it difficult to draw a definitive conclusion on AF prevalence.

Conclusion: These findings limit the possible roles of gene transcriptional changes in previously reported age-dependent pro-arrhythmic electrophysiologial changes observed in Pgc-1β-/- atria to an altered Ca2+-ATPase (Atp2a2) expression. This directly parallels previously reported arrhythmic mechanism associated with p21-activated kinase type 1 deficiency. This could add to contributions from the direct physiological outcomes of mitochondrial dysfunction, whether through reactive oxygen species (ROS) production or altered Ca2+ homeostasis. Introduction Atrial arrhythmias constitute a major public health probl...

Atrial fibrillation (AF) is the most common cardiac arrhythmia observed in clinical practice, and its incidence and prevalence have been progressively increasing with a rise in the aging population and lifestyle changes [1,2]. AF not only affects a patient ’s quality of life due to distressing symptoms but also leads to serious long-term consequences such as stroke and heart failure [3]. The pathophysiology underlying the onset and progression of AF is a complex process that remains unclear despite thorough investigation over the past 3 decades.

Both diseases share associated risk factors – hypertension, diabetes mellitus, sleep apnea, obesity and smoking. Moreover, inflammation plays a causative role in both diseases. The prevalence of CAD in patients with AF is from 17% to 46.5% while the prevalence of AF among pati...

The objectives of this review were to (1) discuss how multimorbidity and polypharmacy contributes to the complexity of management among individuals with AF and (2) identify any interventions to manage polypharmacy in relation to AF.Recent FindingsBased on the four landmark clinical trials of novel anticoagulants, the most common comorbidities with AF are hypertension, heart failure, diabetes, stroke and myocardial infarction. Polypharmacy was also found prevalent in 76.5% of patients with AF, with a median of six drugs per patient. Despite the consequences of polypharmacy in AF, there is very little evidence-based interven...

Purpose of review Atrial fibrillation is the most common sustained cardiac arrhythmia, attributable to several factors that may be amenable through lifestyle modification. There is emerging evidence to suggest that the successful management of several cardiovascular risk factors [obesity, hypertension (HTN), diabetes mellitus, and obstructive sleep apnea (OSA)] can lead to fewer complications and atrial fibrillation prevention. However, the long-term sustainability and reproducibility of these effects have yet to be explored in larger studies. This review explores recent findings for exercise and lifestyle modifications ...

Abstract Coronary artery disease (CAD) is the most common cardiovascular disease while atrial fibrillation (AF) is the most common cardiac arrhythmia. Both diseases share associated risk factors - hypertension, diabetes mellitus, sleep apnea, obesity and smoking. Moreover, inflammation plays a causative role in both diseases. The prevalence of CAD in patients with AF is from 17% to 46.5% while the prevalence of AF among patients with CAD is low and it is estimated from 0.2% to 5%. AF is a well-established factor of poor short- and long-term prognosis in patients with acute myocardial infarction (AMI) and is associ...

Abstract Atrial fibrillation (AF) is a common cardiac arrhythmia, and pathological burden can be influenced by environmental factors. The rural environment may influence the burden of AF, although no systematic review studies have been conducted to address this issue. We performed a systematic review of AF screening studies conducted in rural global populations to determine the burden, risk factors, and screening methods surrounding AF in these settings. Out of the 1792 articles gathered from a keyword search of medical databases and reference lists, 18 publications from 11 countries were included in our analysis....

Conclusion This cross-sectional study found binge drinking is associated with an increased risk of having an irregular heartbeat. However, the type of irregular heartbeat found was mainly sinus tachycardia, which isn't life threatening but involves the heart beating at an abnormally fast rate of over 100 heartbeats a minute. This research also has some notable limitations: The ECG recordings from the acute alcohol group were taken using a smartphone application operated outside the manufacturer's recommended environment. The lively atmosphere within the beer tent may have caused inaccurate recordings. The population...
