Study of Coronary Microvascular Dysfunction Effects on Outcomes in Adults With Dilated Cardiomyopathy

What this Trial Is About

This research aims to understand the long-term outlook of coronary microvascular dysfunction in patients who have dilated cardiomyopathy. The main question being studied is whether coronary microvascular dysfunction affects health outcomes in these patients. The study is observational and sponsored by the Second Affiliated Hospital, School of Medicine, Zhejiang University. Participants will undergo coronary angiography to confirm the absence of significant blockages in the major coronary arteries. Angio-IMR, a measurement derived from the angiography, will be used to assess coronary microvascular function. The study groups include patients with and without coronary microvascular dysfunction, classified based on angiography results. During the study, participants will be followed for up to 5 years to monitor major adverse cardiac events. Researchers will collect clinical data and evaluate heart function using echocardiography and blood markers such as BNP or NT-proBNP. The study involves regular assessments to track heart health and the impact of microvascular dysfunction over time.
