Background: Cardiac troponins (cTn) have been reported to be predictors for adverse outcomes in atrial fibrillation (AF), patients, but their actual use is still unclear. Aim: To assess the factors associated with cTn testing in routine practice and evaluate the association with outcomes. Methods: Patients enrolled in the ESC-EHRA EORP-AF General Long-Term Registry were stratified into 3 groups according to cTn levels as (i) cTn not tested, (ii) cTn in range (≤99th percentile), (iii) cTn elevated (>99th percentile). The composite outcome of any thromboembolism /any acute coronary syndrome/cardiovascular (CV) death, defined as Major Adverse Cardiovascular Events (MACE) and all-cause death were the main endpoints. Results: Among 10 445 AF patients (median age 71 years, 40.3% females) cTn were tested in 2834 (27.1%). cTn was elevated in 904/2834 (31.9%) and in-range in 1930/2834 (68.1%) patients. Female sex, in-hospital enrollment, first-detected AF, CV risk factors, history of coronary artery disease, and atypical AF symptoms were independently associated with cTn testing. Elevated cTn were independently associated with a higher risk for MACE (Model 1, hazard ratio [HR] 1.74, 95% confidence interval [CI] 1.40–2.16, Model 2, HR 1.62, 95% CI 1.28–2.05; Model 3 HR 1.76, 95% CI 1.37–2.26) and all-cause death (Model 1, HR 1.45, 95% CI 1.21–1.74; Model 2, HR 1.36, 95% CI 1.12–1.66; Model 3, HR 1.38, 95% CI 1.12–1.71). Conclusions: Elevated cTn levels were associated with an increased risk of all-cause mortality and adverse CV events. Clinical factors that might enhance the need to rule out CAD were associated with cTn testing. © 2022 European Federation of Internal Medicine

An enhanced risk of undesirable events has been described in individuals who take part in mainly high intensity physical activities. Underlying cardiac disorders are the most common cause of sudden death during sports activities. Left ventricular remodeling is associated with a long-term athletic training. Echocardiography is an easy, non-invasive and efficient way to the precise distinction between these exercise-induced changes, called " physiological" hypertrophy, that revert after detraining, and those of cardiac disorders or "pathological" hypertrophy. The identification of a cardiac disease in an athlete usually leads to his disqualification in an attempt to reduce the risk. On the other hand, a false diagnosis of a cardiac disease in an athlete may also lead to disqualification, thus depriving him of the various benefits from sports participation. Pronounced left ventricular dilatation and hypertrophy should always be suspected for underlying cardiac disease. Physiological left ventricular remodeling is associated with normal systolic and diastolic left ventricle function. Both global and regional left ventricle diastolic function should be evaluated. New echocardiographic techniques (tissue Doppler imaging, strain rate) have revealed "super - diastolic" left ventricle function in athletes, adding the new quality in differential diagnosis od athlete's heart syndrome. © 2011 Akadémiai Kiadó, Budapest.
