Corrected QT dispersion improves diagnostic performance of exercise testing in diagnosing coronary artery disease.
To determine the best combination of parameters that would improve the diagnostic performance of exercise testing, coronary angiography plus exercise testing were done on 112 patients with angina pectoris and normal electrocardiogram. The univariate predictors of coronary artery disease included: age > or = 40 years, male sex, hypertension, smoking, development of exertional chest pain, decreas...
متن کاملEffect of coronary artery bypass on QT dispersion
Introduction: QT dispersion (QT Max – QT min) reflects inhomogeneous ventricular depolarization that may provide a substrate for serious arrythmias and is associated with adverse clinical outcomes in patients with coronary artery disease. Some studies have shown reduction in QT dispersion after successful angioplasty due to coronary reperfusion, but effect of coronary artery bypass grafting o...
متن کاملThe impact of chronic hemodialysis on QT dispersion corrected QTdispersion and maximum QT-dispersion
Introduction: Sudden cardiac death is common in patients on hemodialysis and may occur in the immediate postdialysis period when ventricular premature complexes are common. QT dispersion reflecting hetovogelity in ventricle repolarization has been used for predicting patients with risk of malignant arrhythmia and sudden death. The purpose of the study was to assess the effect of hemodialysis on...
متن کاملClinical Implications of Referral Bias in the Diagnostic Performance of Exercise Testing for Coronary Artery Disease
BACKGROUND Exercise testing with echocardiography or myocardial perfusion imaging is widely used to risk-stratify patients with suspected coronary artery disease. However, reports of diagnostic performance rarely adjust for referral bias, and this practice may adversely influence patient care. Therefore, we evaluated the potential impact of referral bias on diagnostic effectiveness and clinical...
متن کاملReferral Bias in the Diagnostic Performance of Exercise Testing with Imaging for Coronary Artery Disease
Purpose: Exercise testing with myocardial perfusion imaging (MPI) or echocardiography (ECHO) is widely used to risk-stratify patients with suspected coronary artery disease (CAD). However, reports of diagnostic performance do not routinely adjust for referral bias, which results from the preferential referral of higher-risk patients to cardiac catheterization, the gold standard. To understand h...
