国内外学者利用各种方法研究老化对心血管功能的影响时认为,老化可以影响左室舒张功能。然而,老化对左室收缩功能有何影响仍存在分歧意见。本文应用平衡法核素心血管造影技术定量分析健康人左室总体和局部射血分数及其与增龄的关系。材料与方法选择健康人44例,(男34人,女10人),年龄23～84岁,经过各种检查无明确心血管及内分泌疾病。其中25人作过核素心血管造影亚(?)
Domestic and foreign scholars using various methods to study the impact of aging on cardiovascular function that the aging can affect left ventricular diastolic function. However, the impact of aging on left ventricular systolic function still exist differences. In this paper, the equilibrium method of radionuclide angiography was used to quantitatively analyze the global left ventricular ejection fraction and local ejection fraction and its relationship with aging. MATERIALS AND METHODS: Forty-four healthy subjects (34 males and 10 females) aged 23-84 years were enrolled in the study. There were no definite cardiovascular and endocrine diseases after various examinations. 25 of whom had nuclear subventricular angiography (?)
