Key result
Abnormal left ventricular isovolumic relaxation time, sex, and significant coronary artery stenosis (≥50%) were independent prognostic factors of prolonged QT dispersion (p<0.05).
Cross-Sectional (n=262)
p-value: p=<0.05
Echocardiographic parameters of left ventricular function, dimension, and mass are associated with increased QT dispersion in patients with coronary artery disease, particularly those with minimal (<50%) angiographic stenosis.
May link LV relaxation time and stenosis to QT dispersion in CAD; leaves open incremental prognostic value.

Jin et al. (2004) conducted a cross-sectional in Coronary artery disease (n=262). Echocardiographic left ventricular parameters and angiographic coronary stenosis was evaluated on Prolonged QT dispersion (p=<0.05). Abnormal left ventricular isovolumic relaxation time, sex, and significant coronary artery stenosis (≥50%) were independent prognostic factors of prolonged QT dispersion (p<0.05).
