1

A condition where blood flow (and therefore oxygen) to a tissue or organ is insufficient, leading to impaired cellular function.

2

The accumulation of excess fluid in the interstitial (tissue) spaces, causing visible swelling.

3

A fatty, cholesterol‑rich deposit that builds up inside arterial walls.

4

The widening of blood vessels due to relaxation of smooth muscle in the vessel walls. This increases blood flow and lowers blood pressure.

5

The narrowing of blood vessels caused by contraction of smooth muscle in vessel walls. This reduces blood flow and increases blood pressure.

6

A chronic condition where blood pressure is consistently elevated above normal ranges. Typically defined as ≥140/90 mmHg (depending on guidelines).

7

Also called primary hypertension. High blood pressure with no identifiable single cause — the most common form (≈90–95% of cases).

8

High blood pressure that results from an identifiable underlying condition, such as: kidney disease endocrine disorders (e.g., hyperaldosteronism) medications (e.g., corticosteroids) sleep apnea

9

A condition where the coronary arteries become narrowed or blocked, usually due to atherosclerotic plaque, reducing oxygen supply to the heart.
