Understanding Hypertension: A Letter to Our Clinic Patients
Understanding Hypertension
A Letter to Our Clinic Patients
Hypertension is one of the most common chronic diseases worldwide and an important risk factor for heart disease, stroke, and kidney disease. Because hypertension often has no obvious symptoms, it is known as the "Silent Killer". Regular blood pressure monitoring, maintaining a healthy lifestyle, and receiving timely treatment are the keys to preventing serious complications.
What Is Hypertension?
Hypertension refers to persistently elevated pressure exerted by blood against the artery walls. Blood pressure consists of two numbers:
- Systolic Blood Pressure – Pressure when the heart contracts.
- Diastolic Blood Pressure – Pressure when the heart relaxes.
According to the latest AHA/ACC Guidelines:
- Systolic ≥130 mmHg
- Diastolic ≥80 mmHg
Blood Pressure Categories
| Category | Systolic | Diastolic |
|---|---|---|
| Normal | <120 | <80 |
| Elevated | 120-129 | <80 |
| Stage 1 | 130-139 | 80-89 |
| Stage 2 | ≥140 | ≥90 |
| Hypertensive Crisis | >180 / 120 | |
