The goal of the study was to determine the diagnostic value of echocardiographic exam supplemented with the use of TDI, in patients with angina pectoris, with the goal to indirectly identify the stenotic/insufficient coronary blood vassal. The echocardiograpghic results were later compared with the results of nuclear perfusion scan. Both results were later compared with findings at coronary angiography. Total of 19 patients was analysed. Echocardiography was performed with an independent interpretation by three physicians blinded for other clinical and laboratory data. After some time (not more than ten days), a cardiac nuclear scintigraphy was performed using conventional gamma cameras in order to identify perfusion defects. As with echocardiography, analyses was conducted independently by three physicians blinded for clinical and laboratory data. Statistical analysis investigated the degree of coloration between abnormalities discovered by TDI and perfusion scintigraphy. All patients were subsequently subject to coronary catheterisation, which was used as the reference method. TDI analysis proved to be surprisingly sensitive and specific. Because of its cost and ease in performing it is routine use should be encouraged, especially in those patients unable to exercise.
