What is Hypertension?
Hypertension is a medical condition characterized by consistently elevated blood pressure levels in the arteries. Specifically, it is defined as having a blood pressure reading of 130/80 mmHg or higher, according to guidelines from the American College of Cardiology and the American Heart Association. This condition can lead to serious health complications, including heart disease, stroke, and kidney damage, as it forces the heart to work harder and can damage blood vessels over time.
How is Hypertension defined?
Hypertension is defined as a chronic medical condition characterized by consistently elevated blood pressure levels, specifically when systolic blood pressure is 130 mmHg or higher, or diastolic blood pressure is 80 mmHg or higher. This definition is established by the American College of Cardiology and the American Heart Association, which classify hypertension into different stages based on these measurements. The prevalence of hypertension affects approximately 45% of adults in the United States, highlighting its significance as a major risk factor for cardiovascular diseases.
What are the different classifications of Hypertension?
Hypertension is classified into two main categories: primary (essential) hypertension and secondary hypertension. Primary hypertension accounts for about 90-95% of cases and has no identifiable cause, often developing gradually over many years. Secondary hypertension, which constitutes about 5-10% of cases, is caused by an underlying condition such as kidney disease, hormonal disorders, or certain medications. This classification is supported by the American College of Cardiology and the American Heart Association, which emphasize the importance of identifying the type of hypertension for effective management and treatment.
How is Hypertension measured?
Hypertension is measured using a sphygmomanometer, which records blood pressure in millimeters of mercury (mmHg). Blood pressure readings consist of two numbers: systolic pressure, which measures the pressure in the arteries when the heart beats, and diastolic pressure, which measures the pressure in the arteries when the heart rests between beats. A typical reading is expressed as systolic over diastolic, for example, 120/80 mmHg. According to the American Heart Association, a reading of 130/80 mmHg or higher is classified as hypertension.
Why is understanding Hypertension important?
Understanding hypertension is important because it is a major risk factor for cardiovascular diseases, which are leading causes of death globally.
