This is an interesting article by Schuijf et al from Leiden, in Hypertension, describing a study performed on a 16-slice Toshiba, without beta-blockers, assessing the usefulness of cardiac CT in triaging patients with hypertension.
31 patients were studied and 243 coronary artery segments could be evaluated. The sensitivity and specificity was 93% and 96% respectively, with an accuracy of 90% (24/31) on a per patient basis. The evaluation of ejection fraction and wall motion abnormality as compared to 2D-echocardiography was also accurate.
The authors suggest that in hypertensives, who have some form of atherosclerotic disease, using cardiac CT as an initial modality to evaluate function and the coronary arteries may be feasible proposition.
