What role does hypertension play in atrial fibrillation?

Hypertension is recognized as a common cardiovascular risk factor that significantly influences the development and progression of atrial fibrillation (AF). Elevated blood pressure can lead to structural and electrical remodeling of the heart, which contributes to the initiation and maintenance of AF. Chronic hypertension causes changes in the atrial tissue, such as fibrosis and dilation, that create a substrate for arrhythmias. As these structural changes occur, the risk for atrial fibrillation increases, making hypertension a critical component in the understanding of AF epidemiology and management. Addressing this risk factor can be an important part of preventative strategies for patients at risk of AF.
