N434: Perfusion test questions
and answers 2024
Angina
a condition of episodes of severe chest pain due to inadequate blood flow
to the myocardium
Causes of angina
increased O2 demand; decrease supply of O2
Stable angina
chest pain that occurs when a person is active or under severe stress;
usually resolves with rest
Unstable angina
chest pain that occurs while a person is at rest and not exerting himself
What is silent ischemia?
Myocardial ischemia that does not cause detectable symptoms
What is prinzmetal's angina?
angina that occurs at rest from substance use, migraines, vasospasm
What is Microvascular angina?
chest pain occurs in the absence of significant CAD or coronary spasm of a
major coronary artery
Coronary Artery disease (CAD)
atherosclerosis of the coronary arteries; most common type of heart
disease and majority of deaths
CAD leads to
angina
