Frequency of returning to work one and six months following percutaneous coronary intervention for acute myocardial infarction.

We conducted an analysis of the frequency and variables associated with early (after 1 month) and late (after 6 months) return to work after percutaneous coronary intervention for acute myocardial infarction in patients who had been randomized in the Stent Primary Angioplasty in Myocardial Infarction trial. Of 450 patients who were employed before the acute myocardial infarction, 230 (51%) returned to work within 1 month with no increases in in-hospital and 1- or 6-month event rates compared with those who did not return to work. Multivariate analysis showed that predictors of early return to work were employment in the United States, no history of smoking, and single-vessel coronary disease. At 6 months, 353 of 435 patients (78%) had returned to work, and multivariate analysis showed that predictors of late return to work were employment in the United States and absence of angina
