Return to work after acute ST-segment elevation myocardial infarction in the modern era of reperfusion by direct percutaneous coronary intervention

Abstract

Background: Previous studies have evaluated return to work after acute ST-segment elevation myocardial infarction (STEMI) treated medically, after bypass surgery or after percutaneous coronary intervention (PCI) for stable coronary artery disease. However, there are few data regarding return to work after acute STEMI treated by direct PCI.

Aims: To analyse the factors influencing return to work after STEMI treated by direct PCI.

Methods: Two hundred consecutive patients who underwent direct PCI for acute STEMI and who were employed at the time of their STEMI were studied. Stents were used in 94% of patients and glycoprotein IIb/IIIa inhibitors in 77%.

Results: Among the 200 patients, 152 (76%) patients returned to work and 48 (24%) did not. Patients who did not return to work did not differ from those who returned to work in terms of time from onset of chest pain to PCI, STEMI location, left ventricular function, extent of vessel disease, PCI technique and success, completeness of revascularization, duration of hospital stay, intrahospital complications and performance of cardiac rehabilitation. Multivariable analysis showed that older age, daytime onset of chest pain, manual labour, rapid call-out of the emergency medical team, unmarried status and a limited number of risk factors were independent predictors of non-return to work.

Conclusion: Age, sociopsychological and occupational factors appear to be the strongest predictors of return to work after STEMI treated by direct PCI. Clinical and procedural factors as well as cardiac rehabilitation appear to have no impact on return to work in this subset of patients.
