Diagnostic performance of electrocardiography in the assessment of significant coronary artery disease and its anatomical size in comparison with coronary angiography.

Background: Current study addressed the predictive value of 12-lead electrocardiogram (ECG) in patients with suspected coronary artery disease (CAD).

Methods: Four hundred consecutive patients with new onset of chest pain were studied. A resting standard 12-lead ECG was recorded and all patients underwent coronary angiography.

Relationship between serum N-terminal Pro Brain Natriuretic Peptide (NT-Pro BNP) level and the severity of coronary artery involvements.

Background: Rapid measuring of B-type natriuretic peptide (BNP) in the emergency departments effectively results in evaluating patients with acute cardiac attacks and has appeared to be a useful prognostic marker of cardiovascular risk. A current study came to address the association between plasma N-terminal pro BNP level and severity of coronary vessels' defects based on Gensini score in patients with stable angina pectoris candidate for coronary angiography.

Methods: The study population consisted of 92 consecutive patients with appearance of stable angina and candidate for coronary angiography.
