An association between volumes of the cardiac chambers and troponin levels in individuals submitted to cardiac coronary computed tomography.

ABSTRACT:

Background

Previous echocardiographic studies have revealed an association between enlarged cardiac chamber volumes and elevated troponin concentrations. An automatic 4-chamber volumetric analysis tool was adopted to investigate this association in patients who underwent cardiac-gated computed tomography angiography (CCTA).

Hypothesis

We hypothesized that troponin concentration within the normal range correlates with cardiac chambers' volumes.

Methods

Serum troponin was obtained from 157 ambulatory patients before undergoing CCTA for nonacute coronary artery evaluation. Volumes of the cardiac chambers and the left ventricular mass were automatically analyzed and indexed to body surface area. Patients with a troponin concentrations within the upper quartile (>0.007 ng/
