High blood pressure, or hypertension, significantly impacts heart health by increasing the risk of cardiovascular diseases like heart attack and stroke. Elevated blood pressure puts excessive strain on the heart and arteries, potentially leading to heart failure and other complications over time. It can cause damage to the arterial walls, promoting plaque buildup and reducing cardiovascular efficiency. Maintaining a healthy lifestyle through regular exercise, balanced nutrition, and stress management is essential in controlling blood pressure and promoting heart health.
