30-day outcome after percutaneous coronary angioplasty in nonagenarians: feasibility and specific considerations in different clinical settings.

Background: Nonagenarians have been systematically excluded from randomized trials dealing with invasive coronary strategies, resulting in a lack of evidence-based guidelines regarding the optimal approach in this population.

Aim: To describe the clinical and procedural characteristics and outcomes of patients 90 years of age or older who were treated with percutaneous coronary interventions (PCI).

Methods: We evaluated the 30-day outcomes of patients 90 years or older who underwent PCI at our institution, comparing the ST-segment elevation myocardial infarction (STEMI) subgroup with the non-STEMI/unstable angina (UA) and stable angina (SA) subgroups, who had been referred for coronary angiography.
