ABSTRACT
BACKGROUND:
Negative U wave is frequent maker of systemic hypertension, aortic or mitral regurgitation and myocardial ischemia. This study was undertaken to determine the diagnostic significance of exercise-induced negative U wave in coronary artery stenosis.METHOD:
72 patients(46 men and 26 women ; 24~66 years of age) with chest pain were analysed with exercised-induced negative U wave and coronary angiographic finding.RESULT:
Exercise-induced negative U wave was seen in 14 patients(19%). Among 14 patients with exercise-induced negative U wave, the predictive value of significant coronary artery stenosis(> or =75% stenosis of major coronary artery) was 71%, Exercise-induced negative U wave is more prevalent in patients with significant coronary artery stenosis(p<0.05).CONCLUSION:
Exercise-induced negative U wave is a good marker of significant coronary artery stenosis.
