Abstract/OtherAbstract:
METHODS AND RESULTS: This study comprises 296 consecutive patients with clinically suspected SAP, no previous cardiac history, and a normal ejection fraction. All patients were examined by colour TDI, exercise electrocardiogram (ECG), and coronary angiography (CAG). Regional longitudinal systolic (s'), early diastolic (e'), and late diastolic (a') myocardial velocities were measured by colour TDI at six mitral annular sites and averaged to provide global estimates. Duke score (DS), including ST depression, chest pain, and exercise capacity, was used as the outcome of the exercise ECG. Patients with an area stenosis of ≥70% in at least one epicardial coronary artery were categorized as having a significant CAD (n= 108) and were compared with patients without significant CAD (n= 188). Both e' [odds ratio (OR): 1.5 (1.1-1.9, P < 0.01) per cm/s decrease] and s' [OR: 1.7 (1.1-2.5, P < 0.05) per cm/s decrease] remained independent predictors of CAD after multivariable adjustment for baseline, exercise ECG, and conventional echocardiographic parameters. Area under the receiver operating characteristic curve (AUC) for exercise ECG and TDI in combination was significantly higher than AUC for exercise ECG alone (0.84 vs. 0.79, P < 0.01).
CONCLUSION: In patients with suspected SAP colour TDI performed at rest is an independent predictor of significant CAD, and colour TDI improves the diagnostic performance of exercise ECG.
