[Stress-Doppler echocardiography in the diagnosis of ischemic heart disease in an ambulatory setting].
Coronary arteriography, bicycle ergometry and transesophageal atrial pacing (TAP) in combination with Doppler echocardiography (stress-Doppler echocardiography) were used to evaluate cardialgias in 30 outpatients. Stress-Doppler echocardiography showed a high (94%) sensitivity and a high (86%) specificity to detect coronary heart disease (CHD). There was a high correlation (r = 0.79, p less than 0.001) between the wall motion values obtained by echocardiography during TAP and coronary rating. The left ventricular (LV) diastolic filling (DF) was studied by pulsed wave Doppler echocardiography in the postpacing period. The Doppler-derived parameters of LV DF obtained in that period appeared to be moderately sensitive (75%) and specific (64%) in detecting CHD. In post-pacing ischemia, the "pseudonormalized" LV filling pattern was observed in 5 of 6 patients (sensitivity 80%) having three-vessel disease and major left (or equivalent) coronary stenosis.
