Objective of the study: To assess the outcome of Percutaneous coronary intervention in elderly in terms of success and complications.
Methods: Retrospective data review of 887 consecutive cases of percutaneous interventions done at Karachi institute of heart diseases from 2015-2020. We divided the patients in three age groups younger (<65 years, n=592); older (65 to 75 years, n=201); and elderly (>=75 years, n=94). Immediate and six months outcomes of in hospital vascular complications, death, myocardial infarction, repeat target lesion revascularization and stroke were compared between these groups.
Result: The vascular complications was in three groups (relative risk 3.2% vs 2.9% vs 4.3% with p=0.56) respectively. The relative risk of periprocedural Myocardial infarction in elderly/older patients was not higher than young patients with (OR of 0.6 with 95% CI 0.3 vs 1.4 with P=0.35), so was the need of repeat target revascularization with (OR of 0.3 95% CI 0.2 vs -1.6 with P=0.85), the risk of stroke following procedure was minimal (OR of 0.7 95% CI 0.4 vs 1.6 P=0.4). The in-hospital mortality was higher in elderly with (OR with 95% CI 1.0 vs 2.0 vs 3.4 P=0.03) in three groups. The six months outcomes of myocardial infarction in elderly were also not higher than younger pts (OR 0.7 vs 0.4 P=0.58). so was the need for repeat target revascularization (OR 0.5 vs 0.3 P=0.6). The six-month mortality in three groups was high in elderly (OR with 95% CI 1.5% vs 3.4% vs 4% with P value of 0.04).
Conclusion: The procedure success in elderly patients was similar to younger patients, but in hospital and six months mortality was higher in elderlies.
