Incidence of atrial fibrillation according to the type of antihypertensive drugs used

Author : Pierre Allain Date : 2010-2-15

Antihypertensive drugs reduce the risk of atrial fibrillation through lowering of arterial pressure but all drugs have not the same efficiency.

Authors, for the majority Swiss, in a paper published in Annals of Internal Medicine of January 19th, 2010, evaluated the risk of atrial fibrillation in hypertensive patients treated by different types of antihypertensives.

Their results show that the risk of atrial of fibrillation, by taking as reference the patients treated by calcium antagonists, is reduced by approximately 25% in patients treated by the other antihypertensives: angiotensin converting enzyme inhibitors, , angiotensin receptor blockers (sartans) and beta-blockers. In this study the use of a diuretic in addition to other types of antihypertensives was possible. Rather similar results were published in 2004.

During the treatment of hypertension, the risk of atrial fibrillation is higher with a calcium antagonist than with an angiotensin converting enzyme inhibitor or an angiotensin receptor blocker.
