OBJECTIVE: Analysis of the in-hospital results, in progressively elderly patients who undergo primary percutaneous coronary intervention (PCI) in the first 24 hours of AMI. METHODS: The patients were divided into three different age groups (60/69, 70/79, and > or = 80 years) and were treated from 7/95 until 12/99. The primary success rate and the occurrence of major clinical events were analyzed at the end of the in-hospital phase. Coronary stent implantation and abciximab use were employed at the intervencionist discretion. RESULTS: We analyzed 201 patients with age ranging from 60 to 93 years, who underwent primary PCI. Patients with ages above 70 were more often female (p=.015). Those with ages above 80 were treated later with PCI (p=.054), and all of them presented with total occlusion of the infarct-related artery. Coronary stents were implanted in 30% of the patients. Procedural success was lower in > or = 80 year old patients (p=.022), and the death rate was higher in > or = 70 years olds (p=.019). Reinfarction and coronary bypass surgery were uncommon events. A trend occurred toward a higher combined incidence of major in-hospital events according to increased age (p=.064). CONCLUSION: Elderly patients ( > or = 70 years) presented with adverse clinical and angiographic profiles and patients > or = 80 years of age obtained reduced TIMI 3 flow success rates after primary PTCA, and those > or = 70 years had a higher death rate.
