ACUTE CORONARY SYNDROME

Cardiology

ACUTE CORONARY SYNDROME

1. ACS is generally caused by atherosclerotic plaque rupture, fissuring, erosion, or a combination with superimposed intra-coronary thrombosis; results in acute ischemia; and is A/W an increased risk of cardiac death and myocardial infarction.

2. Rarely, ACS can be due to occlusion by coronary emboli, congenital abnormalities, coronary spasm, and systemic inflammatory diseases.

3. Two types: unstable angina, STEMI.

4. Patients with NSTEMis have a smaller size of infarcted area and decreased early mortality compared to those with STEMis, but a higher risk for persistent angina, reinfarction, and death within several months!

5. Although NSTEMI have a lower early mortality, they have a higher 6-month mortality.
