title: The effects of off-normal hours, age, and gender for coronary angioplasty on hospital mortality in patients undergoing coronary angioplasty for acute myocardial infarction.
abstract: Percutaneous transluminal coronary angioplasty (PTCA) was performed in all 1,050 patients hospitalized within 24 hours of symptoms of documented acute myocardial infarction (AMI) from 1998 to 2002. Hospital mortality was similar in women and men who underwent PTCA for AMI but was higher in patients aged 75 to 95 years (10%) than in patients aged 21 to 50 (2.1%, p <0.001), 51 to 64 (2.3%, p <0.001), and 65 to 74 years (4%, p <0.02). Hospital mortality was higher in patients who had PTCA for AMI during off-normal (5.8%) than normal hours (3.2%, p <0.05).
