Outline of Final Research Achievements

The number of elderlies with heart disease is increasing in the aging society. Aging is thought to affect the morphology and function of the heart even in the healthy population, but there is no data of the elderly aged 75 or over. Therefore, in this study, echocardiography was performed in the healthy elderly population over 75 years of age to evaluate changes in left ventricular morphology and function with aging. There was a gender difference in the size of the left ventricle, and in particular, left ventricle in women tended to become smaller with age. However, these reflect differences in physique, and correction with body surface area eliminated the effects of gender difference and aging. Sex differences were found in the left ventricular function, and it was revealed that a slight excess of contraction and diastolic dysfunction progressed in women.

Academic Significance and Societal Importance of the Research Achievements

後期高齢者では加齢によって体格が小さくになるにつれて左室が小さくなることが明らかになった。また、男女間での機能には差があり、生命予後の観点から更なる研究が必要である。
