Cardiac conditions Flashcards
1
Q
Prinzmetal angina
A
Indicated by ST elevation during stress test
2
Q
Cardiac syndrome X
A
Indicated by ST depression and angina during stress test. Diagnosis of exclusion
3
Q
Prinzmetal angina
A
Caused by coronary artery vasospasm
4
Q
Cardiac syndrome X
A
Caused by microvascular dysfunction
5
Q
Causes of resting ST elevation
A
MI, pericarditis, left bundle branch block, left ventricular hypertrophy, coronary artery spasm, LV aneurysm, ventricular pacing, early repolarization
6
Q
Hibernating myocardium
A
Chronically underperfused myocardium. Perfusion may restore normal contractility
7
Q
Reperfusion injury
A
Occurs 1 hour after perfusion with further irreversible myocardial damage
8
Q
Stunned myocardium
A
Caused by acute ischemia. Function may be restored 7-10 days after perfusion
