Study Notes
Blood Pressure and Hypertension
- Systolic blood pressure is the pressure in the arteries when the heart beats (during contractions).
- Hypertension is a major health problem because it can cause damage to organs such as the heart, brain, and kidneys, without noticeable symptoms.
- Primary or essential hypertension is the primary cause of high blood pressure in most cases, accounting for around 90-95% of cases.
- Hypertension is defined as a systolic blood pressure of 140 mmHg or higher or a diastolic blood pressure of 90 mmHg or higher.
- The primary cause of primary or essential hypertension is still not fully understood, but it is thought to be related to a combination of genetic, lifestyle, and environmental factors.
- Systolic blood pressure is characterized by its peak pressure during heart contractions.
- Hypertension is more common in people above 40 years of age.
