What Are the Basics of Systolic Hypertension and Diastolic Hypertension?

Millimeters of mercury (mmHg) is used to measure blood pressure. Normally blood pressure is expressed in terms of the systolic pressure over diastolic pressure. And the systolic pressure refers to the maximum during one heart beat while diastolic pressure refers to the minimum between two heart beats. When the systolic blood pressure continues to rise, you may get systolic hypertension, and when your diastolic blood pressure is below the normal range, you may get diastolic hypertension.

What is systolic hypertension?

Systolic hypertension refers to the elevated systolic blood pressure (SBP). Isolated systolic hypertension is a common form of systolic hypertension, it will occur when your systolic blood pressure is elevated (>140) while your diastolic blood pressure (DBP) keeps normal.

What are the causes of systolic hypertension?

The main cause of systolic hypertension is aging. With age, the compliance of the aorta will be reduced which will increase the load on the ventricle and may lead to heart failure, left ventricular hypertrophy and coronary ischemia. All these conditions may lead to systolic hypertension.

What is diastolic hypertension?

Diastolic hypertension refers to the elevated diastolic blood pressure (SBP). When your diastolic pressure reaches 90 mmHg or higher, you have higher risk of getting it. Isolated diastolic hypertension (IDH) is a common form of diastolic hypertension and it is primarily seen in younger adults.

What are the causes of diastolic hypertension?

Possible causes of diastolic hypertension include:

  • Endocrine and Kidney diseases.
  • Sleep Apnea.
  • Chronic excessive alcohol consumption.
  • Aging.
  • Overweight or obese.
  • Some medicines such as nonsteroidal anti-inflammatory drugs, oral contraceptives, and corticosteroids.
