Background:Local study regarding association between frontal QRS-T Angle on electrocardiography and mortality may help develop guidelines to reduce morbidity and mortality in heart failure.
Objective: To determine the association between Frontal QRS-T Angle on electrocardiography and mortality in patients with heart failure.
Material and Methods:A Prospective Cohort Study was conducted from January 2021 to December 2022 in different cardiology departments of Punjab province. A total of 672 consecutive patients i.e. 336 with high QRS T Frontal angle (group A with angle > 900) and 336 with normal QRS T Frontal angle presenting with heart failure to outpatient and emergency department were matriculated for the study. All patients were followed for any adverse event i.e. mortality for three months by telephone on first of every month. Presence of diabetes & hypertension and history of smoking were treated as effect modifier.
Results: 672 patients were included in our sample with mean age of 57.86 ± 5.8 years. 466 patients (69.3%) were male while remaining 206 patients (30.7%) were female. 145 patients (21.6%) died within three months. 110 patients with raised QRS T frontal angle died within three months while only 35 patients with normal QRS T frontal angle died within three months. Diabetes, hypertension, smoking, male gender and age were significant contributor to mortality. Conclusion:It is concluded that there is association of raised QRS T frontal angle (> 900) with mortality in patients with heart failure. QRS T frontal angle can be used as cost effective sign of increased risk of mortality in patients with heart failure.
