Prethrombotic State and Cardiac Events in Patients With Coronary Heart Disease During Noncardiac Surgery

This study aimed to investigate the significance of the prethrombotic state (PTS) and 4 plasma markers in predicting perisurgical adverse cardiac events in patients with coronary heart disease (CHD) undergoing abdominal surgery. Perioperative adverse effects were recorded in 128 consecutive patients with CHD undergoing elective abdominal surgery. Plasma d-dimer, P-selectin, von Willebrand factor (VWF), and thrombus precursor protein were measured before and after the surgery. Patients with abnormal values in one or more of the 4 PTS markers were identified as having PTS, and data were analyzed by univariate and multivariate logistic regression. Abnormal presurgery levels of the 4 markers were found more frequently in those with adverse perioperative cardiac events than in those without. Multivariate analysis showed the odds ratios for adverse cardiac events to be 64.3 (PTS, P < .001), 25.7 (VWF, P = .003), and 23.5 (P-selectin, P = .04). Preoperative PTS is an independent risk factor for perioperative events in patients with CHD undergoing noncardiac surgery.
