Abstract

Background
The aim of the study was to investigate the severity of coronary artery disease (CAD) in patients who had a planar QRS-T angle >90 degrees versus Material and Method
Coronary angiography was performed in 1,229 consecutive patients. Obstructive CAD was diagnosed if there was >50% obstruction of >or=1 major coronary artery. All QRS-T angle measurements were made from a 12-lead electrocardiogram by 2 authors who agreed on the measurement and who were blinded to the coronary angiographic findings. A QRS-T angle >90 degrees was considered abnormal.
Results
Obstructive CAD of 2 or 3 vessels was present in 309 of 495 patients (62%) with a planar QRS-T angle >90 degrees and in 250 of 734 patients (34%) with a planar QRS-T angle or=30 kg/m2 (odds ratio =1.5).
Conclusions
The prevalence of 2- or 3-vessel obstructive CAD was significantly higher in patients with a planar QRS-T angle >90 degrees than in patients with a planar QRS-T angle
