Understanding Blood Pressure
Blood pressure measures the force of blood against artery walls. It's recorded as two numbers: systolic (top) and diastolic (bottom).
Key Metrics:
- Systolic: Pressure when heart contracts
- Diastolic: Pressure when heart relaxes
- MAP: Average pressure in arteries during one cardiac cycle
- Pulse Pressure: Difference between systolic and diastolic
Risk Factors
Factors that increase risk of high blood pressure:
- Age (risk increases with age)
- Family history of hypertension
