Comparison of outcomes in young versus nonyoung patients with ST elevation myocardial infarction treated by primary angioplasty

OBJECTIVESWe sought to determine in-hospital and intermediate-term outcomes of primary percutaneous coronary intervention (PCI) for ST elevation myocardial infarction (STEMI) in young adults. METHODSWe reviewed 2424 consecutive patients treated with primary angioplasty for acute MI; 465 were aged 45 or less (young group) and 1959 were 46–74 years of age (nonyoung group). Clinical characteristics, in-hospital and intermediate-term outcomes of primary PCI were analyzed. RESULTSCompared with nonyoung patients, the young patients had significantly lower in-hospital and intermediate-term mortality (for in-hospital mortaliy5.4 vs. 1.2%, P
