Official Title: Evaluation of the Correlation Between Coronary Microvascular Resistance Based on Quantitative Flow Ratio and Major Adverse Cardiovascular Events in Patients With Obstructive Hypertrophic Cardiomyopath
Brief Summary:
About 60% of patients with hypertrophic cardiomyopathy have microvascular dysfunction. Microvascular dysfunction is directly related to prognosis in hypertrophic cardiomyopathy. This new measurement method is microcirculation resistance (MR) based on quantitative flow ratio (QFR), which does not need a pressure guide wire on the basis of angiography. The QFR system is used to evaluate the blood vessels distal pressure and blood flow, and their ratio is microcirculation resistance (MR). The quantitative blood flow…
