Abstract Objective To study the value of cardiac magnetic resonance (CMR) in the evaluation of right heart structure and function in chronic heart failure. Methods From January 2016 to December 2017, in the Fifth People′s Hospital of Chengdu, 32 patients with CHF were chosen as observation group, another 32 healthy person who received physical examination at the same period were chosen as control group. CMR examination was performed in both groups, and the right heart structure and function indexes of two groups were compared, such as right ventricular thickness (RVT), right ventricular mass (RVM), right ventricular papillary muscle mass (RVPM), right ventricular end diastolic volume (RVEDV), right ventricular systolic volume (RVESV), right ventricular stroke volume (RVSV), right ventricular ejection fraction (RVEF). Results The RVT, RVM, RVPM, RVEDV, RVESV and RVSV of the right ventricle in the observation group were significantly higher than those in the control group, the RVEF was significantly lower than that in the control group, the differences were statistically significant (P < 0.05 or P < 0.01). Conclusion CMR can quantitatively analyze the right ventricular structure and function of patients with CHF, which helps to determine the patients′ disease progression.
