BACKGROUND: Drug-eluting coronary stents are the most recent "breakthrough" technology in interventional cardiology. Whereas risk factors influencing restenosis and need for target vessel revascularization are well known, risk factors for dying or developing a myocardial infarction (MI) after drug-eluting coronary stent implantation need to be evaluated yet.
METHODS: We evaluated data from the German Cypher Stent Registry.
RESULTS: From April 2002 to December 2004, 7445 patients at 122 hospitals, who received at least one sirolimus-eluting stent during percutaneous coronary intervention, were included. Complete follow-up at a median of 6.6 months (quartiles 6.1-8.1 months) was available in 6755 patients (91%). Death occurred in 1.8% (120/6755) of patients, nonfatal MI in 2.3% (156/6635), and death or MI in 4.1% (276/6755) of patients. Independent predictors of death or MI were initial presentation with ST-elevation MI or non-ST-elevation MI (OR [odds ratio] 2.21, 95% CI 1.66-2.95, P < .0001), cardiogenic shock (OR 3.05, 95% CI 1.67-5.55, P = .0003), renal insufficiency (OR 1.74, 95% CI 1.24-2.44, P = .0017), reduced left ventricular function (OR 1.74, 95% CI 1.21-2.50, P = .0027), age (per decade) (OR 1.19, 95% CI 1.05-1.36, P = .0058), diabetes mellitus (OR 1.39, 95% CI 1.05-1.84, P = .0183), 3-vessel disease (OR 1.32, 95% CI 0.99-1.77, P = .043), and prior MI (OR 1.35, 95% CI 1.01-1.80, P = .0468), whereas interventional and lesion characteristics showed no significant association.
CONCLUSIONS: These results demonstrate that the most powerful predictors of death or MI after sirolimus-eluting stent implantation during percutaneous coronary intervention are presentation with an acute coronary syndrome, impaired left ventricular ejection fraction, and conventional risk factors for coronary heart disease. Interventional and lesion characteristics do not play a major role.
