The Role of Blood Pressure in Cardiovascular Health
Blood pressure plays a crucial role in maintaining cardiovascular health. It refers to the force exerted by blood against the walls of arteries as the heart pumps.
Normal blood pressure is essential for proper blood flow throughout the body. The ideal range is generally considered to be below 120/80 mmHg.
High blood pressure, or hypertension, is a major risk factor for cardiovascular disease. It can damage arteries and increase the workload on the heart over time.
Uncontrolled hypertension significantly raises the risk of:
- Heart attack
- Stroke
- Heart failure
- Kidney disease
Essential hypertension, with no identifiable cause, is the most common form. It often develops gradually over many years.
Effective management of hypertension is key to preventing cardiovascular complications. This typically involves lifestyle changes and may include medication.
Regular blood pressure monitoring is important for early detection and treatment of hypertension. This can help reduce the risk of serious cardiovascular events.
Maintaining healthy blood pressure levels through diet, exercise, and stress management contributes to overall heart health and longevity.
