A Cohort Study of PCI Strategies for Severely Calcified Lesions of Complex Coronary Arteries in the Elderly
Henan Institute of Cardiovascular Epidemiology
2,100 participants
Dec 25, 2023
OBSERVATIONAL
Conditions
Summary
The aim of this observational study is to compare the prognostic outcomes of various PCI strategies in elderly patients with complex coronary calcified lesions. The patients will be classified into two groups and assigned different PCI strategies, either stenting or stenting combined with pharmacologic balloon implantation. The investigators will assess the one-year prognosis for major adverse cardiovascular events in these patients.
