“ASSOCIATION OF QTc DISPERSION WITH CORONARY ANGIOGRAPHIC SEVERITY IN PATIENTS OF CHRONIC CORONARY SYNDROMES”

Abstract

Coronary artery disease (CAD) is a major health concern globally, with a particularly 
high burden in South Asian countries like Bangladesh. Patients with suspected or 
established chronic coronary syndromes (CCS) are: (i) patients with suspected CAD 
and ‘stable’ angina symptoms, and/or dyspnea; (ii) patients with new onset of heart 
failure (HF) or left ventricular (LV) dysfunction and suspected CAD; (iii) 
asymptomatic and symptomatic patients with stabilized symptoms < 1 year after an 
ACS or patients with recent revascularization (iv) asymptomatic and symptomatic 
patients with stabilized symptoms >1 year after initial diagnosis or revascularization; 
(v) patients with angina and suspected vasospastic or microvascular disease; and (vi) 
asymptomatic subjects in whom CAD is detected at screening[1]. The prevalence of 
chronic stable angina (CSA) in Bangladesh has been reported to be 25.9% [2]. 
However, Bangladesh is a small country with vast population and CAD is becoming a 
significant burden on health care services in Bangladesh as well with a high mortality 
[3]. The South Asian countries of India, Pakistan, Bangladesh, Sri Lanka and Nepal 
contribute the highest proportion of the burden of Cardiovascular Diseases (CVDs) 
compared to any other region globally
