Abstract

The purpose of this study was to investigate the effect of left ventricular diastolic function on exercise capacity in hypertensive patients with obesity compared to the obese group. Adults who visited a general hospital in Gyeonggi-do from 2016 to 2019(man: 308, women: 192) were divided into 4 groups according to hypertension and obesity. In the hypertensive obesity group(IV), the A wave and E/E' wave were significantly higher than the normotensive obesity group(II), and the E' wave was significantly lower(respectively p<0.001). The group IV had significantly lower METS(metabolic equivalents) and exercise duration than the group II(respectively p<0.001). In group IV, E/A ratio was positively correlated with METS(p=0.025) and exercise duration(p=0.026). In contrast, E/E' wave in these groups showed a negative correlation with the exercise duration(p=0.046).

이 연구는 비만군과 비교해 비만을 동반한 고혈압 환자에서 좌심실 이완기 기능 및 운동능력의 차이를 평가하고 좌심실 이완기 기능이 운동능력에 미치는 영향을 알아보고자 하였다. 2016년 1월부터 2019년 8월까지 경기도 지역종합병원을 내원한 남성 308명, 여성 197명을 대상으로 하였다. 고혈압과 비만 유무에 따라 대상자를 4그룹으로 나누었다. 비만 단독환자보다 비만을 동반한 고혈압 환자에서 이완기 기능을 나타내는 A파와 E/E'파는 높았으며, E'파는 낮았다(각각 p<0.001). 운동능력은 비만군보다 비만을 동반한 고혈압 환자에서 대사당량과 운동지속시간이 낮았다(각각 p<0.001). 비만을 동반한 고혈압 환자에서 E/A 비율은 대사당량에 정적인 영향을 미쳤다(p=0.025). 또한 E/A 비율은 운동지속시간에 정적인 영향을 미치며(p=0.026), E/E'파는 부적인 영향을 미치는 것으로 나타났다(p=0.046).
