['The present study evaluated whether elevated cardiac troponin T (cTnT) was predictive of an increased risk for death or amputation in patients with acute lower limb ischemia (ALI). ALI is one of the most frequent causes of amputation, with mortality rates for ALI ranging from 15% to 20%.', 'This study included 254 consecutive ALI patients (155 men, 99 women; mean age, 71.6 ± 13.2 years) presenting with Rutherford categories I, IIA, or IIB according to the classification for ALI.', 'ALI was caused by thromboembolism (29.5%), local arterial thrombosis (53.1%), or bypass graft occlusion (16.9%). Restoration of arterial blood flow was obtained by an endovascular approach, with a primary success rate of 98.4%. Rates were low for in-hospital mortality (3.9%) and amputation (5.1%). Patients who died or required amputation more frequently presented with elevated cTnT ≥0.01 ng/mL (52.2% vs 25.5%, P = .01) and impaired renal function (chronic kidney disease stage 3-5; 60.9% vs 38.1%; P = .04). After controlling for age, sex, C-reactive protein, renal function, presence or absence of coronary artery disease, and traditional vascular risk factors, as well as the interval between symptom onset and revascularization, the relationship between cTnT and a worse in-hospital outcome remained significant (hazard ratio, 3.4; 95% confidence interval, 1.3-8.5; P = .010).'] Does elevated cardiac troponin T contribute to prediction of worse in-hospital outcomes after endovascular therapy for acute limb ischemia?
