What is blood pressure?
Blood pressure is the pressure of the circulating blood on the walls of the blood vessels. Hypertension or high blood pressure is when this pressure of the blood on the artery walls is consistently high. The heart pumps out oxygenated blood to the rest of the body to help it function. Systolic pressure is the pressure inside the artery when the heart pumps out blood to the rest of the body. Diastolic pressure is the pressure inside the artery when the heart rests between beats.
High blood pressure damages the heart by:
- Making the heart work harder to counteract the increased pressure in the arteries.
- This increased pressure also injures the delicate inner lining of the arteries, making it open to the development of plaque, which is the beginning of atherosclerosis. This can lead to a heart attack or stroke.
- The elevated blood pressure and the narrowing of the arteries brings about a vicious cycle of damage to the heart and blood vessels.
- The increased work of the heart leads to its thickening or enlargement and makes it less efficient and eventual heart failure.
