association of the high-sensitive cardiac troponin t levels and long-term mortality in patients with acute aortic dissection type a

Introduction: acute aortic dissection type a is a life-threatening cardiovascular emergency necessitating rapid diagnosis and treatment. we sought a new prognostic tool with cardiac biomarkers and simple inflammatory factors. methods: from 2003 to 2014, 50 patients with documented acute aortic dissection type a were entered to this study. these patients were followed up until december 2020; within median follow up of 93.6 months. the patients were evaluated on the association of the baseline characteristics, first laboratory investigation, echocardiographic findings, surgical approach, and long-term mortality. results: total number of mortality during the follow up was 29 (58%) patients, which was significantly higher in medical group (89.4% vs 38.7%, p value=0.001). multivariable analysis showed only an increase in hs-ctnt levels was suggested as a predictor of mortality (95% ci: 1.06–1.38; hr=1.21; p=0.005), so that for every 100 units increase, patients were 21% more likely to have mortality in long term. also, performing surgical treatment for aortic dissection was determined as the independent predictor of surviving, so that death was 74.6% less than those who received medical treatment (95% ci: 0.13–0.58; hr=0.27; p=0.001). conclusion: hs-ctnt is a potential predictor of mortality in patients with acute aortic dissection type a.
