Abstract

Several novel ECG markers are proposed to predict the risk of sudden cardiac death in several clinical conditions in the recent years. However, little is known about the association of pericardial fat or obesity with these markers. To assess the possible relationship between pericardial fat volume (PFV) and body mass index (BMI) with novel ECG markers (Tp-e, Tp-e/QT, Tp-e/QTc*QRS and QTc/QRS) in patients with coronary atherosclerosis. We enrolled 100 patients with suspected coronary artery disease who underwent 64-slice multi-detector CT angiography. Higher values of Tp-e/QTc*QRS and QTc/QRS were observed among high PFV group in comparison to low PFV group particularly in patient with coronary atherosclerosis and these relationships persisted after adjustment for cardiac risk factors and coronary calcium score (CAC) while no significant differences in QTc, Tp-e, Tp-e/QTc and Tp-e/QRS values were observed between the PFV groups in patients without coronary atherosclerosis. There was no significant difference in QTc, Tp-e/QTc, Tp-e/QRS, Tp-e/QTc*QRS and QTc/QRS observed between the BMI groups either in patients with and without coronary atherosclerosis. PFV and not obesity measured by BMI is significantly associated with novel EC...Continue Reading

Cardiac Conduction System

The cardiac conduction system is a specialized tract of myocardial cells responsible for maintaining normal cardiac rhythm. Discover the latest research on the cardiac conduction system here.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Cardiovascular Diseases: Risk Factors

Cardiovascular disease is a significant health concern. Risk factors include hypertension, obesity, dyslipidemia and smoking. Women who are postmenopausal are at an increased risk of heart disease. Here is the latest research for risk factors of cardiovascular disease.
