In Prinzmetal’s angina
(A) Generally Right Coronary Artery presents as inferior wall MI (B) Coronary artery spasm most commonly occurs distal to atherosclerotic area. (C) No changes in ECG, Q wave become normal after few hours. (D) All of the above
(D) Pain at rest.
Variant may hence ST↓.
An inferior wall myocardial infarction — also known as IWMI, or inferior MI, or inferior ST segment elevation MI, or inferior STEMI — occurs when inferior myocardial tissue supplied by the right coronary artery, or RCA, is injured due to thrombosis of that vessel.
LAD (Left Anterior Descending Artery) may be involved.
ECG no change.
Wave become normal after few hours.
Coronary artery may be normal.
Coronary artery Spasm most commonly occurs distal to the atherosclerotic area.
