Systolic and diastolic blood pressure are two important measurements used to determine a person’s blood pressure reading. Blood pressure is typically measured in millimeters of mercury (mm Hg) and is expressed as two numbers, the systolic blood pressure and the diastolic blood pressure.
Systolic blood pressure is the first number recorded and measures the pressure in the arteries when the heart beats. This occurs when the heart is contracting and pumping blood into the arteries. Systolic blood pressure is considered a good indicator of overall cardiovascular health and is used to evaluate the risk of developing heart disease and other health problems.
Diastolic blood pressure, on the other hand, is the second number recorded and measures the pressure in the arteries when the heart is at rest between beats. This is when the heart is relaxing and filling with blood. Elevated diastolic blood pressure is a strong predictor of heart disease, particularly in older adults.
A normal blood pressure reading is typically considered to be below 120/80 mm Hg. Readings above this are considered elevated and may indicate the presence of hypertension, or high blood pressure. If a person has a systolic blood pressure reading of 140 mm Hg or higher, or a diastolic blood pressure reading of 90 mm Hg or higher, they are considered to have hypertension.
It is important to regularly monitor your blood pressure to ensure that it remains within a healthy range. If your blood pressure is elevated, your doctor may recommend lifestyle changes, such as a healthy diet and regular exercise, or may prescribe medication to help control it. Regular monitoring of blood pressure is an important step in maintaining good heart health and reducing the risk of heart disease and other health problems.
