Abstract [en]

BACKGROUND:

Data on contemporary real-world outcomes of interventional revascularization in patients > or = 75 y of age with ST elevation infarction (STEMI) are limited.

METHODS:

We analyzed all 504 consecutive patients who underwent angiography for acute STEMI between 1999 and 2005 at our center, and followed them up over one year. Outcomes in patients > or = 75 y of age were compared with younger patients.

RESULTS:

Patients > or = 75 y of age (n = 115) were majority females (55% versus 21%, p < 0.001), more cases of diabetes (42% versus 27%, p = 0.004), hypertension (78% versus 65%, p = 0.03) and a history of coronary events (25% versus 15%, p = 0.002). Younger patients were more often smokers (63% versus 30%, p < 0.001). After coronary angiography patients > or = 75 y of age underwent less frequent intervention (PCI; 84% versus 93%, p = 0.01). However, if PCI was performed, technical success rates were similar to younger patients (84% versus 86%). The 30-d mortality was 13% versus 6.4% (p = 0.03), but after successful PCI, the 30-d mortality rate was not significantly higher in old patients (7.4% versus 3.9%, p = 0.23). Bleeding complications were very low in both age groups if the radial access route was chosen. Multivariate predictors of 30-d mortality were cardiogenic shock/survived cardiac arrest, ejection fraction < 30%, conservative treatment or unsuccessful PCI (OR 3.01), renal insufficiency, diabetes, and age. One-y mortality was higher in the elderly (24.3% versus 9.9%, p < 0.001). Among 30-d-survivors, only multivessel disease and age were multivariate predictors of 1-y mortality.

CONCLUSION:

Patients > or = 75 y of age benefit from PCI in STEMI, and failed or unattempted PCI worsens prognosis in the old as well as in younger patients.
