1. Sudden and severe elevation in blood pressure (systolic ≥180 mmHg and/or diastolic ≥120 mmHg)

2. Absence of acute target organ damage (e.g., no evidence of acute heart failure, stroke, myocardial infarction, or acute kidney injury)

3. Patient may present with symptoms such as headache, shortness of breath, epistaxis (nosebleed), or anxiety, but without signs of end-organ dysfunction

4. Blood pressure elevation confirmed by repeated measurements in a clinical setting

5. No prior diagnosis of chronic hypertension crisis or hypertensive emergency
