Heart Disease

What Causes High Blood Pressure?

Blood pressure is the term used to describe the pressure exerted on the arterial walls as blood flows through them. This pressure is at its highest when the heart contracts and pumps blood through the arteries and is called the systolic pressure.

New 2025 guidelines focus on early intervention and lifestyle to manage high blood pressure

Preventing and managing high blood pressure with healthy lifestyle behaviors, such as following a heart-healthy diet including reducing salt intake, staying physically active, maintaining a healthy weight and managing stress—combined with early treatment with medication to lower blood pressure if necessary—are recommended to reduce the risk of heart attack, stroke, heart failure, kidney disease, cognitive decline and dementia, according to a new clinical guideline published today in the American Heart Association's peer-reviewed journals Circulation and Hypertension, and in JACC, the flagship journal of the American College of Cardiology.
