Introduction and objective:
Percutaneous coronary intervention (PCI) is the method of choice for the treatment of coronary artery disease or acute coronary syndromes, but clinicians often refrain from performing it on elderly and/or frail patients. The aimed of the study was to determine the feasibility of PCI in the elderly, and define characteristics of significant stenoses and clinical outcomes of those procedures.

Material and methods:
A retrospective analysis was conducted on a total of 150 patients aged ≥70 years, who were admitted and underwent PCI between November 2020 – December.2021. Also investgated was the impact of patients’ baseline characteristics, such as: gender, body mass index (BMI) or comorbidities: hyperlipidaemia, hypertension, diabetes, etc. on clinical outcomes of PCI performed in the elderly.

The mean age was 77.5 ± 7.1 years, 65.33% were male. The average BMI was 27.5 ± 4.3, 92.00% had a history of HT. The majority of patients (n=84) were treated for acute coronary syndromes (ACS). The mean length of stents implanted in one procedure was 31mm. The TIMI 3 flow was achieved in 94.67% of cases. Combined intra-procedural and in-hospital mortality was 2.67%.

Complex PCI may be successfully and safely performed among elderly patients who frequently suffer from severe myocardial ischemia and carry a substantial comorbidity burden. Age itself cannot warrant disqualification from interventional management of coronary artery disease. Gender and BMI are potential factors that influence clinical outcomes.
