  • 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).

  • Resting gated blood pool scan was used to derive left ventricular functional changes in normals (N=13, mean age=43) and in patients with coronary artery disease (N=50, mean age=53). Peak filling rates, average filling rates, and ejection fractions were significantly depressed in coronary artery disease. (p<0.0005, each other). And in coronary artery disease with normal ejection fraction (N=21), peak filling rates and average filling rates were depressed also, and peak filling rates of coronary artery disease with normal ejection fraction were abnormal in 61.2% and average fillin rates were abnormal in 71.4%. It appears that (1) resting peak filling rates and average filling rates were sensitive and easily obtainable parameters of the diastolic dysfunction assosiated with coronary artery disease, (2) a significant proportion of coronary artery disease patients without any evidence of abnormal systolic function have depressed resting peak filling rates and average filling rates of the left ventricle.
