Introduction: Myocardial dysfunction is a common complication in patients with sepsis. Cardiac troponins and natriuretic peptides are biomarkers that were previously introduced for diagnosis and risk stratifi cation in patients with acute coronary syndrome and congestive heart failure, respectively. However, their prognostic and diagnostic impact in critically ill patients warrants defi nition. Materials And Methods: Patients admitted to the intensive care unit (ICU) between January 2009 to January 2010 of a tertiary care center, who fulfi lled the already reported consensus criteria for septic shock were included in this study. Results: Sixty-eight patients with septic shock meeting entry criteria were retrospectively studied. 64.7% patients were found to have positive troponins (Troponin I> 0.05). Twenty-four (35.29%) patients had troponin I < 0.05 ng/ml and compromised the troponin I negative group. Th e mean (S.D) serum troponin I value in troponin I ?positive group was 2.55 ? 1.67 ng/ml. None of the patient had progressive EKG changes. Clinical Outcomes In Terms Of Troponins: Th e Troponin I-positive group had higher APACHE II score (30? 6 Vs 22 ? 4.7) on admission. Twenty-eight patients died in the total study and among them twenty patients (71.42%) had elevated troponin I. Left ventricular dysfunction was more common in troponin-I positive group (EF= 38 ? 10) than in Troponin I-negative group (EF= 52 ? 6.5). 63.63 % of the patients with elevated Troponin I required mechanical ventilation as compared to 50% patients with normal Troponin I levels. Th e patients with elevated troponin I levels had longer MICU stay ( 7.45 vs 5.28 days) Clinical Outcomes In Term Of Probnp: Among Twenty-eight deaths in this study, 66.66 % patients had elevated Pro BNP. Left Ventricular dysfunction was more common in patients with elevated Pro-BNP (EF= 42 ? 8.2 vs EF =52 ? 10). 76.67 % patients who needed mechanical ventilation had elevated Pro-BNP. Similarly 67.82 % patients on inotropic support had elevated Pro-BNP. Elevated Pro-BNP was also found to be associated with increase in MICU stay (6.72 vs 4.35 days) Conclusion: To date, it is unclear whether clinically unrecognized myocardial cell injury accompanies, causes, or results from this decreased cardiac performance. Th ese fi ndings suggest that in septic shock, clinically unrecognized myocardial cell injury is a marker of LV dysfunction.
