1. Hypertension Pathophysiology

Key Concepts & Definitions

  • Hypertension: A chronic condition characterized by persistently elevated blood pressure, typically ≥130/80 mmHg, increasing risk for cardiovascular events.
  • Primary (Essential) Hypertension: Hypertension with no identifiable secondary cause, resulting from complex interactions of genetic, environmental, and lifestyle factors.
  • Secondary Hypertension: Elevated BP caused by an underlying condition such as renal disease, endocrine disorders, or medication effects.
  • Vasoconstriction: Narrowing of blood vessels due to contraction of vascular smooth muscle, leading to increased peripheral resistance and BP.
  • Renin-Angiotensin-Aldosterone System (RAAS): Hormonal cascade that regulates blood pressure and fluid balance; overactivation contributes to hypertension.
  • Peripheral Resistance: The resistance to blood flow in the small arteries and arterioles, a key determinant of systemic blood pressure.

Flashcards preview

Hypertension — pathophysiology?

Increased peripheral resistance and volume expansion.

Hypertension — definition?

High blood pressure ≥130/80 mmHg.

ACE inhibitors — role?

Block angiotensin II formation, causing vasodilation.

Primary vs secondary hypertension — difference?

Primary no identifiable cause; secondary due to underlying condition.

Diuretics — mechanism?

Increase renal sodium and water excretion.

Vasoconstriction — effect on BP?

Increases peripheral resistance and BP.
