What this Trial Is About
Researchers are studying coronary microvascular disease (CMD), a type of non-obstructive coronary heart disease characterized by angina without major artery narrowing. CMD's detection is increasing, and it significantly affects patients' quality of life and raises the risk of cardiovascular events. The study aims to observe the development and outcomes of CMD and explore its underlying mechanisms. This observational study will prospectively collect patients diagnosed with CMD based on angina symptoms, evidence of myocardial ischemia, and coronary angiography showing normal or mildly narrowed vessels. Participants will be followed over time to gather data on disease progression and outcomes, contributing to establishing a CMD patient registry in China. Participants will undergo clinical assessments to document their angina symptoms and ischemia evidence. Researchers will collect detailed information to observe disease development and outcomes over five years. The primary goal is to create a comprehensive registry of CMD patients, which will help improve understanding of the disease and its impact on patients' health.
