“…4); however, in the individual patient the score is not helpful to predict the severity of coronary stenosis, due to the considerable overlap of the values. Consistent with previous scintigraphic and echocardiographic studies [17][18][19][20], sensitivity was highest in patients with more severe lesions, of 70% or more, confirming that the prevalence of an ischemic response is primarily related to the severity of coronary stenosis. Based on our previous experience [12][13][14]21], these positive results cannot be extended to patients with disease of left circumflex or right coronary artery, in which the sensitivity of exercise echocardiography is slightly lower than that obtained by SPECT.…”

To compare the diagnostic value of exercise echocardiography and perfusion single photon emission computed tomography (SPECT) in the detection of the presence and the severity of coronary artery disease, we studied 21 patients with isolated stenosis of different degree of the left anterior descending artery. Both echocardiography and SPECT were performed in conjunction with the same symptom-limited bicycle exercise test. Positivity of the test was based on the presence of exercise-induced wall motion abnormalities and transient perfusion defects, respectively. For both tests, an 'ischemic' score was derived, as index of extent and severity of myocardial ischemia. Coronary arteriography was evaluated by caliper.The agreement between exercise echocardiography and SPECT for the presence of coronary artery disease was 90%; the discordance was due to two patients with positive echocardiography and negative SPECT. A good correlation between ischemic wall motion and perfusion score indices was found (r = 0.78, p < 0.0001. Moreover, the percent diameter stenosis was well correlated with both ischemic indices (r = 0.75, p < 0.0001; r = 0.67, p < 0.001, respectively). In patients with a positive test, the mean value of ischemic wall motion score index was higher in patients with a diameter stenosis -70% than in patients with a diameter stenosis <70% (0.59 + 0.19 vs 0.29 + 0.12, p < 0.01); a similar trend was found for ischemic perfusion score index (0.51 + 0.35 vs 0.27 _+ 0.12, ns).The results of this study indicate that in patients with single vessel disease of left anterior descending artery exercise echocardiography and SPECT give the same information on the presence, the extent and the severity of myocardial ischemia.

“…ARAS is generally evaluated using the diameter reduction as an index; this parameter, which is expressed as a percentage (% diameter reduction), is calculated as the relative reduction in the lumen diameter by an atheromatous lesion observed on angiography (1,2). Its use as an index for coronary artery stenosis, a context in which it is well correlated with cardiac perfusion (9)(10)(11), is believed to have influenced its use as an index for ARAS. However, the % diameter reduction is thought to be less effective for ARAS than for coronary artery stenosis; both its proximal and distal reference diameters which greatly influence the % diameter reduction, are frequently obscure, because ARAS often exists near the orifice of the renal artery and accompanies poststenotic dilatation (12).…”

“…To evaluate the efficacy of modern therapeutic procedures in the catheterization laboratory,9 8 Over the last few years there has been an increasing interest in quantitation of coronary cineangiograms. The various systems used to date vary to a great extent, from manual procedures that implement a vernier caliper or comparable device'2-7 to a computerized manual edge-tracing procedure'8 and methods that make use of computer edge detection algorithms to determine arterial dimensions in a two-dimensional projection.…”
