Study Notes
Hypertension (HTN)
- HTN results from increased peripheral vascular arteriolar smooth muscle tone, leading to increased arteriolar resistance and reduced capacitance of the venous system.
- The cause of elevated vascular tone is unknown.
Risk Factors and Complications of HTN
- HTN is a risk factor for:
- Chronic kidney disease
- Myocardial infarction (MI)
- Heart failure
- Stroke
- Blindness
Etiology of HTN
- Essential HTN: accounts for 90% of patients with unknown cause.
- Predisposing factors for HTN:
- Diabetes
- Obesity
- Stressful lifestyle
- High intake of sodium
- Smoking
- Race
- Family history
