增龄过程中肥胖程度对心脏功能及结构的影响

以超声心图检测一组３５８健康成人心脏功能及解剖超声测值，通过多元逐步加及直线相关分析其与有相关关系，研究增龄过程中肥胖程度对心脏功能结构的影响，结果；正常健康人群随体量相中增加；左房、左室、右室及主动脉中内径增大；可能舒张功能的改变。结果肥胖程度与主解剖结构的显著相关关系与增龄及血压变化无关，提示肥胖对心血管系统的影响，在健康成件人群心血阳以相应重视。

Obesity Impact on Cardiac Function and Structure during Advancing Age

An echocardiographic test was applied to a series of 385 healthy adults to mea-sure their cardiac functions andanatomic ultrasonic dimensions,which were analyzed with multi-variate stepwise regression and linear correlation to probe the relationship with the level of obesityand the effect of obesity on the cardiac function and structure during advancing age. As a result,systemic blood pressure,rest cardiac output and stroke volume went up with the increase of bodyweight,body mass index(BMI),and ratio between body weight and body height;the interven-tricular septum and the left ventricular posterior wall thicken up,and the left ventricular muscleaugmented relevantly;the internal dimensions were enlarged at the left atrium,the left and rightventricles,and the aortic root;the left ventricular function might be effected.The result showedthat blood pressure and aging were independent of the significant correlations between the level ofobesity and the measurements of cardiac function and structure,It suggested that the impact ofobesity on cardiovascular system should be considered adequately for the early prophylaxis ofsome cardiovascular diseases in healthy adult population.
