[Abstract] Objective: To compare the differences in cardiac structure and function between healthy and normal people in the plateau and plain areas by cardiac magnetic resonance imaging (CMRI).Materials and Methods: One hundred normal healthy people underwent CMRI (n=50 each from plateau and plains areas). Cardiac structural parameters, such as anterior wall thickness of interventricular septum (AWOIVS), left atrial diameter (LAD), left ventricular end diastolic diameter (LVEDD), aortic diameter (AOD), main pulmonary artery diameter (MPAD), right atrial transverse diameter (RATD), right atrium long diameter (RALD), right ventricular transaction diameter (RVTD) and right ventricular long diameter (RVLD), and left ventricular functional parameters were measured. Independent-sample t-test was used to compare and analyse the differences in parameters between the two groups.Results: In the cardiac structure, the AWOIVS and MPAD in the plateau group were significantly larger than those in the plain group (P<0.05), and the LVEDD in the plateau group was significantly smaller than the plain group. (P<0.05). In the left heart function, the LVEDV in the plateau group was significantly smaller than that in the plain group (P<0.05). The LVEF in the plateau group was larger than that in the plain group, and the difference was not statistically significant (P>0.05).Conclusions: Compared with healthy people in plain area, healthy normal people in plateau area have some changes in heart structure and function, with increased thickness of anterior ventricular septum, wider inner diameter of main pulmonary artery, and reduced left ventricular volume. Healthy normal people in plateau area have strong heart reserve capacity and oxygen uptake capacity.
