Hypertension and Atrial Fibrillation: Doubts and Certainties From Basic and Clinical Studies

Area of Science:

• Cardiology
• Public Health
• Epidemiology

Background:

• Hypertension and atrial fibrillation (AF) are prevalent global health concerns.
• These conditions frequently coexist and are linked to increased cardiovascular disease and mortality.
• Hypertension is a primary risk factor for AF, contributing to a significant number of cases.

Purpose of the Study:

• To elucidate the pathogenic mechanisms linking hypertension to AF.
• To review epidemiological evidence on the hypertension-AF relationship and blood pressure control.
• To examine the comparative effectiveness of anticoagulants in hypertensive AF patients.

Main Methods:

• Review of basic pathogenetic mechanisms of hypertension-induced AF.
• Analysis of epidemiological data on blood pressure and AF risk.
• Evaluation of evidence on intensive blood pressure control and specific antihypertensive drugs.
• Comparison of non-vitamin K antagonist oral anticoagulants (NOACs) with warfarin in hypertensive AF patients.

Main Results:

• Hypertension promotes AF through incompletely understood mechanisms.
• The relationship between blood pressure levels and AF risk may be progressive.
• Evidence suggests intensive blood pressure control and renin-angiotensin-aldosterone system inhibitors might lower AF risk.
• Comparative data on anticoagulants in hypertensive AF patients are examined.

Conclusions:

• Understanding hypertension's role in AF is crucial for public health.
• Further research is needed to clarify optimal blood pressure targets and treatment strategies.
• Specific antihypertensive therapies may play a role in AF prevention and management.
