Grades of hypertension

Definition

Grades of hypertension classify the severity of high blood pressure based on systolic and diastolic measurements. These grades help guide treatment decisions and risk assessment.

5 Must Know Facts For Your Next Test

1. Grade 1 hypertension is defined as systolic BP between 130-139 mmHg or diastolic BP between 80-89 mmHg.
2. Grade 2 hypertension is characterized by systolic BP between 140-159 mmHg or diastolic BP between 90-99 mmHg.
3. Grade 3 hypertension, or severe hypertension, involves a systolic BP of ≥160 mmHg or diastolic BP of ≥100 mmHg.
4. Hypertension management often begins with lifestyle modifications and may progress to pharmacological treatments depending on the grade.
5. Uncontrolled high-grade hypertension can lead to serious complications such as stroke, myocardial infarction, and renal failure.
