• De Ritis ratio predicts 3-year all-cause mortality after acute myocardial infarction. • De Ritis ratio predicts 3-year cardiac mortality after acute myocardial infarction. • De Ritis ratio predicts 30-day risk of bleeding after percutaneous coronary intervention. • De Ritis ratio has a moderate sensitivity regarding prediction of mortality. The association between aspartate aminotransferase to alanine aminotransferase ratio (De Ritis ratio) and prognosis of patients with acute myocardial infarction (AMI) remains poorly investigated. This study included 3000 patients with AMI undergoing percutaneous coronary intervention. Patients were categorized in groups according to tertiles of the De Ritis ratio: tertile 1 (De Ritis ratio < 1.11; 905 patients), tertile 2 (De Ritis ratio 1.11 to 1.95; 1003 patients) and tertile 3 (De Ritis ratio > 1.95; 1002 patients). The primary endpoint was 3-year all-cause mortality. At 3 years, all-cause deaths occurred in 487 patients: 119 deaths (13.2%) in patients of 1st tertile, 164 deaths (17.8%) in patients of 2nd tertile and 204 deaths (21.9%) in patients of 3rd tertile of the De Ritis ratio (adjusted hazard ratio [HR] = 1.16, 95% confidence interval [CI] 1.02 to 1.31], P = 0.023 per unit increment in the logarithmic scale of the De Ritis ratio); cardiac deaths occurred in 328 patients: 76 deaths (8.2%) in patients of 1st tertile, 110 deaths (12.0%) in patients of 2nd tertile and 142 deaths (15.4%) in patients of 3rd tertile of the De Ritis ratio (adjusted HR = 1.20 [1.04–1.40], P = 0.014 per unit increment in the logarithmic scale of De Ritis ratio). The C-statistic of the multivariable model(s) with baseline data without and with De Ritis ratio was 0.822 [0.805–0.839] and 0.823 [0.805–0.840], (P = 0.419) for all-cause mortality and 0.831[0.811–0.852] and 0.832 [0.811–0.853], P = 0.621) for cardiac mortality. In patients with AMI, elevated De Ritis ratio was associated with increased risk of 3-year mortality. [ABSTRACT FROM AUTHOR]

• Tenascin-C is expressed in diseased hearts, not in normal hearts. • Clinical utility of Tenascin-C in diseased heart is unclear. • Tenascin-C was independently associated with acute myocardial infarction, cardiomyopathy, diabetic retinopathy. • Tenascin could predict cardiovascular outcomes in patient with stable coronary heart disease. We investigated the prognostic value of tenascin-C in patients with stable coronary heart disease. A total of 666 patients were enrolled and followed for 72 months. The primary outcome was a composite of cardiac events. The secondary outcomes were all-cause death, cardiovascular death, acute myocardial infarction (AMI), and heart failure hospitalization. Results: The area under the curve of tenascin-C to discriminate the occurrence of composite cardiac events was 70 % (95 % CI: 64.2 % to 75.8 %), and the corresponding optimal cutoff value was 19.91 ng/ml. A higher concentration of tenascin-C was associated with a greater risk of composite cardiac events (P trend < 0.001). Similar results were observed in all-cause death, AMI, and heart failure hospitalization. Tenascin-C was found to be an independent predictor of total cardiovascular events in patients with stable coronary heart disease at 72 months, and also for all-cause death, AMI, and heart failure hospitalization.
