[Outcomes of percutaneous coronary intervention in patients over 90 years with acute coronary syndrome.]

A single-center, retrospective study included 41 patients over 90 years of age who underwent primary percutaneous coronary intervention for the treatment of acute coronary syndrome in the period from 01.2019 to 01.2023. Based on electrocardiography data, patients were divided into 2 groups: Group 1 (n=21) with ST-segment elevation acute coronary syndrome (ST-ACS), Group 2 (n=20) with non-ST-segment elevation acute coronary syndrome (NSTE-ACS). Multivessel coronary artery disease was detected in 71% of cases in STE-ACS versus 65% of cases in the NSTE-ACS group (p=0,658). Moreover, simultaneous complete revascularization was predominantly performed in NSTE-ACS (p=0,043). The length of stay in the intensive care unit was comparable (p=0,575), as was the overall length of hospital stay (p=0,463). In-hospital mortality was 35% for NSTE-ACS and 38,1% for STE-ACS (p=0,837). The incidence of hospital-acquired pneumonia, stroke, and bleeding did not differ significantly between the comparison groups. According to the data obtained, patients over 90 years of age with acute coronary syndrome with and without ST-segment elevation can successfully and safely undergo percutaneous coronary intervention.
