[Abstract] Objectives: To evaluate the global function of the left and right ventricle using MRI in the patients with hypertrophic cardiomyopathy.Materials and Methods: Twenty-six patients who were diagnosed with hypertrophic cardiomyopathy were collected. All the patients and twenty volunteers were performed cardiac magnetic resonance. All the images were analyzed by two radiologists using the software of ReportCARD3.6. The end-diastolic volume(EDV), end-systolic volume(ESV), stroke volume(SV) , ejection fraction(EF) and fractional shortening(FS) were acquired. The global function of the left and right ventricle of patients and volunteers were compared with independent-sample t test.Results: Respectively, the left EDV、ESV、EF、SV and FS of patients’were (88.94±13.29) ml、(24.75±7.31) ml、(71.70±7.60) %、(64.20±12.82) ml、(52.52±8.83) %, respectively, the left EDV、ESV、EF、SV and FS of volunteers’were (107.93±12.62) ml、(34.18±3.6) ml、(67.25±4.48) %、(73.65±12.41) ml、(36.8±3.82) %, EDV、ESV、SV were lower than that of volunteers, there is significant difference between the two groups; EF was higher than that of volunteers, but there is no significant difference between the two groups; FS were higher than that of volunteers, there is significant difference between the two.Respectively, the right EDV、ESV、EF、SV of patients’were (88.48±17.67) ml、(29.84±7.50) ml、(64.65±10.27) %、(58.66±17.09) ml, respectively, the right EDV、ESV、EF、SV of volunteers’were (142.31±23.62) ml、(72.49±16.13) ml、(49.18±5.6) %、(69.82±13.43) ml, EDV、ESV were lower than that of volunteers, there is significant difference between the two groups; EF was higher than that of volunteers, there is significant difference between the two; SV is lower than that of volunteers, there is no significant difference between the two.Conclusions: The change of left and right ventricular were similar. To hypertrophic cardiomyopathy patient, the left ventricle diastolic function decrease and the systolic function increase in the early time. Meanwhile, the right ventricle diastolic function decrease and the systolic function increase.
