Abstract
SummaryIohexol sodium, a nonionic radiographic contrast medium, used in invasive imaging techniques has been shown to be potentially thrombogenic. In the present study, the effect of iohexol sodium on haemostatic factors was evaluated in 20 patients, 16 male and 4 female, 10 undergoing coronary angiography and another 10 undergoing coronary angioplasty. All the patients had angiographically-assessed coronary artery disease. The patients undergoing coronary angioplasty received a significantly larger quantity of the dye as compared with the patients undergoing coronary angiography. The former group of patients also received a bolus of 20,000 units of standard heparin in addition. The levels of thrombin-antithrombin-III complex (TAT), prothrombin fragments 1 and 2 (F1F2), D-dimer and the functional activity of tissue factor pathway inhibitor (TFPI) were assayed. While the baseline and 30-min post-dye levels of TAT and F1F2 were comparable in patients undergoing coronary angioplasty, the 30 min levels were significantly elevated in patients undergoing coronary angiography. The post-dye levels of TFPI activity were significantly increased in the former group due to the heparin-induced release of TFPI. It is concluded that the thrombogenic potential of iohexol sodium was overcome by heparin used routinely during coronary angioplasty.
