Clinical evaluation of cardiac magnetic resonance for coronary microcirculation dysfunction

Myocardial infarction is a serious threat to people’s lives and health. Currently, percutaneous coronary intervention (PCI) is one of the important means to rebuild coronary blood vessels and restore myocardial reperfusion, but clinically some patients have microvascular dysfunction or obstruction. Their blood supply is abnormal and there is no reflow or slow blood flow in the coronary artery after reperfusion. In recent years, the unique advantages of accurate assessment and prevention of coronary microvascular disease by cardiac magnetic resonance (CMR) in improving clinical prognosis have been shown and valued, and its safety, flexibility and accuracy of cardiac structure and function assessment have been clinically affirmed. This article describes the clinical evaluation and application value of CMR in microvascular lesions after PCI, with a view to exploring the prospect of precise treatment of coronary microcirculation disorders.
