Prognostic value of elevated cardiac troponin I in patients with intracerebral hemorrhage

Abstract Aim The aim of this study is to assess the prognostic value of cardiac troponin I as a predictor of in-hospital morbidity and mortality in patients with infective endocarditis. Methods This study included 48 patients with definite and possible IE according to modified Duke’s criteria for diagnosis of IE. This prospective longitudinal study was conducted on patients admitted to the cardiovascular department of Cairo University hospitals. All patients were subjected to full history taking and clinical examination, all laboratory and radiological investigations which included chest radiography, echocardiogram and other diagnostic procedures as needed for diagnosis and follow-up of IE were done with emphasis on cardiac troponin I level on admission. Results Troponin I was found to be statistically significant predictor for heart failure (NYHA III/IV), septic pulmonary embolism and in-hospital mortality in infective endocarditis patients by univariate and multivariate regression analysis with P values 0.023, 0.037and 0.002 respectively. Tricuspid valve vegetations had showed significant relation to troponin I levels with p value 0.033. Also it was found that SOFA score on first day of admission showed significant relation to troponin I level with P value 0.045 and 0.004 for prediction of hospital stay duration. Shock and intracranial hemorrhage showed borderline significance with P values 0.097, 0.069. On other hand, troponin I as predictor of pulmonary edema, mechanical complications, systemic embolization, acute kidney injury and presence of aortic root abscess had no statistical significance in our studied patients. Conclusions This study showed that there is as significant predictive value of elevated cardiac troponin I with heart failure, septic pulmonary embolism and all cause in-hospital mortality. In addition, it was significant predictor of the length of hospital stay, lymphocytosis and SOFA score. These results are emphasizing that cTn I level may predict higher risk patients who would need early and aggressive control of infection medically alone or combined with surgery in IE patients.

Abstract Background Sepsis is heterogenous with regard to factors such as causal microorganism, patient predisposition, co-morbidity and response to therapy, a key element and unifying feature is the manifestation of cardiovascular dysfunction. Elevated concentrations of cardiac troponin I (cTnI) are frequently observed in patients with severe sepsis and septic shock even in the absence of an acute coronary syndrome (ACS). Objective To evaluate the prognostic value of (cTnI) with echocardiography assessment in septic patients. Patients and Methods This study was conducted at the intensive care units of Ain Shams university hospitals. 20 patients of both sexes with age ranging from 18 to 70 years diagnosed with sepsis admitted to Intensive care unit were included in prospective observational study. Results Baseline cTnI had a significant positive correlation with follow up troponine (p = 0.0016). Baseline EF had a significant negative correlation with follow up troponine (p = 0.036). Using ROC-curve analysis, troponin level at a cutoff point (>1.9) predicted patients with mortality, with good (87%) accuracy, sensitivity= 90% and specificity= 90% (p < 0.01). Conclusion Elevated concentrations of cardiac troponin I (cTnI) are frequently observed in patients with sepsis and septic shock even in the absence of an acute coronary syndrome.
