Exercise Capacity According to Coronary Microvascular Dysfunction and Body Composition
Sponsor: Korea University Anam Hospital
Summary
The correlation of coronary microvascular function and body composition with cardiopulmonary exercise capacity will be assessed in patients with heart failure with preserved ejection fraction.

Interventions
Adenosine stress echocardiography with the evaluation of coronary artery blood flow
The color Doppler flow of distal left anterior descending artery will be examined from the modified apical four-chamber view in the anterior interventricular groove. In regard to body composition analysis, Using InBody S10, impedance is measured in 6 frequency bands (1 kilohertz (kHz), 5 kHz, 50 kHz, 250 kHz, 500 kHz, 1000 kHz) for each of 5 parts (right plate, left arm, torso, right leg, left leg). Reactance is measured in 3 frequency bands (5 kHz, 50 kHz, 250 kHz for each of 5 parts (right arm, left arm, torso, right leg, left leg). By treadmill exercise test with modified Bruce protocol or bicycle ergometer for patients with orthopedic problems, maximal oxygen consumption (VO2 max) will be measured using the exhalation gas analysis.
