All statements are true regarding non-ST elevation acute coronary syndromes (NSTE-ACS) and ST elevation myocardial infarctions (STEMI) except ?
Correct Answer: Infarction of >=60% of the left ventricle usually results in cardiogenic shock
Description: Epidemiologic studies indicate there is a shift in the pattern of AMI over the last 15 years with more patients with NSTEMI than STEMI.The relative incidence of NSTEMI is rising due to the increasing burden of diabetes and chronic kidney disease in an aging population, while STEMI is declining due to greater use of aspirin, statins, and less smoking. Among patients with NSTE-ACS, the propoion with NSTEMI is rising while that with UA is falling because of the wider use of troponin assays with higher sensitivity to detect myocyte necrosis, thereby reclassifying UA as NSTEMI. Infarction of >=40% of the left ventricle usually results in cardiogenic shock. Pump failure is now the primary cause of in-hospital death from STEMI PCI is the treatment of choice for patients with acute coronary syndromes
