Relation between the Left Ventricular Mass and the Left Coronary Artery Dimensions as Determined by 16-Channel Multidetector CT: Comparison between the Normotensive group and the Hypertensive Group

Abstract

Purpose: The purpose of this study is to determine the left ventricular mass (LVM) and the left coronary artery dimension and to investigate the relationship between the two values in the normotensive group and hypertensive group with using 16-channel multidetector CT (MDCT). Materials and Methods: Among the patients who underwent a CT coronary angiogram procedure using 16-channel MDCT at Ajou University Hospital from October 2004 to February 2005, 33 patients became the subjects of this study. These 33 patients showed normal findings without calcification or stenosis of the coronary arteries. The total volume of the left ventricular wall was calculated using work-in-progress cardiac CT reconstruction software. The LVM could then be directly calculated by multiplying the left ventricular muscle volume by the myocardial tissue density, which was assumed to be 1.05 g/cm 3

“…First, spiral CT of the head was performed without application of contrast agent, to detect a potential intracranial haemorrhage, edema or ischemia. Afterwards ECG-gated contrast enhanced Cardio-CT was performed in standard-technique [43,44]. To obtain a high opacification of the coronary arteries bolus tracking was applied.…”
