Flashcards
Cause of IHD
Cause of IHD
Reduced blood flow to the heart muscle due to narrowed or blocked coronary arteries.
Epicardial artery blockage
Epicardial artery blockage
Complete blockage of major heart arteries leads to increased resistance in smaller blood vessels.
Ischemia at rest
Ischemia at rest
Severe narrowing of the coronary arteries (over 70%) causes symptoms even when the heart isn't working hard.
