Ticagrelor Versus Clopidogrel for CMD in Patients With AMI: A Retrospective Study Based on the Angio-IMR
NCT05978726 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 325
Last updated 2023-08-07
Summary
Coronary microvascular dysfunction (CMD) is increasingly recognized as an important indicator for long-term prognosis in patients with acute myocardial infarction (AMI). The angiography-derived index of microcirculatory resistance (angio-IMR) is a novel guidewire-free measure for CMD in patients with AMI. Ticagrelor has recently been suggested to have additional benefits on coronary microcirculation beyond its antiplatelet effect. This study was designed to compare the protective effects of ticagrelor and clopidogrel on CMD and prognostic impact in patients with AMI, using the angio-IMR as a novel assessment tool.
Conditions
Interventions
- DRUG
-
Dual antiplatelet therapy with aspirin and either ticagrelor or clopidogrel
Patients with acute myocardial infarction randomly received dual antiplatelet therapy with with aspirin 100mg daily and either ticagrelor 90mg twice daily or clopidogrel 75mg once daily for at least 9 months after PCI as needed.
