Abstract:
Objective To compare echocardiogram and cardiac magnetic resonance imaging (MRI) for diagnosis of hypertrophic cardiomyopathy. Methods A total of 137 patients suspected of hypertrophic cardiomyopathy were recruited. All patients received three-dimensional echocardiogram followed by cardiac MRI, and the detection rate of hypertrophic cardiomyopathy was compared. Results A total of 96 eligible patients with hypertrophic cardiomyopathy were finally enrolledin this study, including 70 males (72.9%) and 26 females (27.1%), with a mean age of 48.2 ± 10.2 years. There was a significant difference in the detection rate of hypertrophic cardiomyopathy by echocardiogram (93.8%) and by cardiac MRI (100%) (χ2 = 4.30, P = 0.03). Among the 96 subjects, there was no significant difference in the mean value of maximum left ventricular wall thickness measured by echocardiogram and cardiac MRI (22.1 ± 8.9 vs 22.8 ± 9.2 mm; t = 1.23, P = 0.32). There was a significant difference in the mean thickness of the basal anterolateral free wall in the left ventricle (18.2 ± 7.8 vs 13.9 ± 7.1 mm; t = 9.40, P = 0.0007). Conclusion Cardiac MRI scanning is superior to echocardiogram for diagnosis of hypertrophic cardiomyopathy, which may be used as an effective supplement to conventional echocardiogram.
