AIM to analyze the incidence of coronary heart disease or myocardial bridge (MB) in patients with hypertrophic cardiomyopathy (HCM) who have undergone coronary angiography (CAG), so as to provide guidance for the clinical treatment of such patients.
METHODS coronary angiography was performed in 118 patients with suspected coronary heart disease (CHD) diagnosed with HCM by clinical manifestation, electrocardiogram and echocardiography, and the prevalence of CAD(> 50% main branch stenosis) and MB was assessed.
RESULTS in patients with HCM, CAD and MB morbidity rates were 18.6% and44.1% respectively (Nobel classification Ⅰ level 22%, 9.3% 7.6%, Ⅱ Ⅲ level), there are both CAD and the prevalence of MB was 5.1%. Nobel Ⅱ, Ⅲ MB in patients with HOCM incidence increased significantly.
Conclusions CAG is a feasible and accurate invasive method for HCM patients with coronary heart disease. When the patient is over 40 years old, has the risk factors of coronary heart disease such as hypertension and diabetes, and has the dynamic changes of severe chest pain and ECG, CAG is needed to exclude HCM with coronary heart disease. disease risk factors such as hypertension, diabetes, severe chest pain and ecg dynamic changes, ICA is required to exclude HCM combined with CAD.
