Background: Atrial fibrillation (AF) is a type of arrhythmia that represents a severe health hazard. The current therapies for AF have achieved success in some conditions. However, because the mechanisms underlying the occurrence and development of this disease remain unclear, the current treatment for AF often does not achieve the desired outcomes. Angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs), which exert robust effects on specific cardiovascular diseases, are widely used in the clinic. Several studies are focusing on the effect of ACEIs/ARBs on the prevention and cure of AF. Some systematic reviews have obtained different and even opposite results. An overview is required to obtain a conclusion and provide strong evidence to guide clinical work.Methods: We searched 5 databases, including MEDLINE, EMBASE, Cochrane Library, Web of Science, and CNKI (Chinese), and selected relevant reviews that passed the assessment we performed. Then, we synthesized the data for each result from the included reviews and obtained conclusions.Results: ACEIs/ARBs prevented new-onset AF and AF after heart failure. ACEIs/ARBs performed well in the prevention of secondary AF, especially postoperative AF. However, for patients suffering from hypertension and myocardial infarction, ACEIs/ARBs were not the right choices for preventing AF.Conclusions: We suggest that physicians select ACEIs/ARBs as an anti-AF therapy for patients with heart failure due to their additional benefits. Moreover, for patients who have suffered AF, ACEIs/ARBs may be a routine drug for secondary prevention.
