“…The 22 studies included countries in America (the U.S and Canada), Europe (the U.K., Netherlands, Denmark, and the Czech Republic), Asia (Japan, Pakistan, India), and Africa (sub-Saharan Africa, Nigeria, and Ghana). Together, the11 registries and 22 HF studies only evaluated a few types of HF, which included thyrotoxic HF [27][28][29][30][31], HFrEF [18,23,25,[32][33][34][36][37][38][39][40], ischemic [34,41], HFpEF [25,35], HFmEF [25], hypertensive [18,23,26,47,48], right HF [18], and systolic HF [42][43][44][45][46].…”

“…The bulk of the studies defined HF types based on structural and/or functional abnormalities. These studies mostly categorized HF by quantifying LVEF into HFrEF, HFpEF, HFmEF, and systolic HF [18,23,25,[32][33][34][35][36][37][38][39][40][41][42][43][44][45][46]. Other studies categorized HF type based on the causative agent rather than functional changes but, in effect, relied on LVEF values to confirm HF diagnosis.…”

“…Further analysis examined the prevalence of AF in different HF types. The included registries and studies examined 9 types of HF -HFmEF [25], HFpEF [25,35], HFrEF [18,23,25,32,33,[35][36][37][38][39][40], high output HF [23], hypertensive HF [18,23,26,48], ischemic HF [34,41], right HF [18,23], systolic HF [42][43][44][45][46], and thyrotoxic HF [27][28][29][30][31]. The prevalence of AF across these nine HF types varied significantly.…”

The present paper performed a meta-analysis of 11 heart failure (HF) registries and 22 studies (N=292,927; mean age=71.8 years; females=43%) that evaluated arrhythmias in HF. The aim was to determine the prevalence and common types of arrhythmias in different forms of HF. Despite the prevalence of arrhythmias in all forms of heart failure (HF) and their association with a substantial risk of hospitalization, morbidity, and mortality, the search for studies finds that ECG-defined arrhythmias remain an understudied pathology in HF populations. Original studies on arrhythmias in HF populations are lacking, with a majority only reporting atrial fibrillation (AF) and ventricular tachycardia or fibrillation (VT/VF) during index admission as the underlying disease or precipitating factor. VT/VF received disproportionate focus because they confer substantial risk of thromboembolism and sudden cardiac death, respectively. The event rate of AF was 32.7% (95% CI: 31.1-34.3) and VT was 32.0% (95% CI: 12.2-61.3) in the 11 registries and AF occurred in 32.7% (95% CI: 32.5-33.0) in the 22 HF studies. Data on the prevalence of other forms of arrhythmias was either unavailable or insufficient for a pooled analysis. The prevalence of AF was observed in hypertensive HF, HF with reduced/ preserved ejection fraction, right HF, systolic HF, ischemic HF, and thyrotoxic HF. Given that arrhythmias can be both a cause and a consequence of HF, it is important to determine the prevalence of the different types of arrhythmias in different HF populations to improve diagnosis and refine management.
