Abstract:
Objective: To establish a mini invasive way to evaluate endothelium function. Methods: Group 1 consisted of 10 subjects with no risk factors for coronary artery disease, group 2 consisted of 11 subjects with risk factors for coronary artery disease and angiographically normal coronary arteries. Two groups of patients underwent transesophageal echocardiography(TEE) for assessment of LAD diastolic blood flow velocity (V) and time velocity integral (VTI) at rest (B 1), 2 min after immersion of the hand in cold water (CPT), 5 min after rewarming of the extremity (B 2), and 5 min after administered nitroglycerin. The percent change in V and VTI were calculated between B 1 and CTP and B 2 and nitroglycerin. Results: After CPT the percent increase in V and VTI were significant in group 1 than group 2 ( P
