• Hypertension: systolic BP ≥140 mmHg or diastolic BP ≥90 mmHg, or both.

• Severe hypertension: sustained BP elevations for a minimum of 4 hours with systolic BP ≥160 mmHg and/or diastolic BP ≥110 mmHg. In severe hypertension, the diagnosis may need to be confirmed within a shorter interval (minutes) between BP measurements.
