Abstract:
Objective To study the changes of cardiac structure,heart function and pulmonary arterial pressure of the Han Chinese back to the plain after living long time on Tibetan Plateau. Methods Randomly choose 67 cases out of the Han people who have moved to the Tibetan Plateau many years , and been examined to make sure they have no disease caused by other factors. Examine their cardiac structure, heart function, pulmonary arterial pressure and valve flow velocity in Tibetan Plateau and about 60 days later back in plains respectively. Then make statistical analysis of high altitude cardiopulmonary adaptation and de-adaptation reaction according to the differences. Results Only were the values of pulmonary artery systolic pressure (PASP) and tricuspid regurgitation (TR) from the group back to plains lower than those from the group migrated to plateau (P = 0.045; P = 0.041). Other indicators of cardiac structure, heart function, pulmonary arterial pressure and valve flow velocity did not change significantly between the group back to plains and the group migrated to plateau (P > 0.05). Conclusions To Han people who returned to plains about 60 days later after long time staying on plateau , only the values of PASP and TR significantly reduce , which have not recovered to normal levels. This may be correlated with the ageing factor and long time migrating.
