BackgroundCancer patients present a high risk of sepsis and are exposed to cardiotoxic drugs during chemotherapy. Myocardial dysfunction is common during septic shock and can be evaluated at bedside using echocardiography. The aim of this study was to identify early cardiac dysfunctions associated with intensive care unit (ICU) mortality in cancer patients presenting with septic shock.MethodsSeventy-two cancer patients admitted to the ICU underwent echocardiography within 48 h of developing septic shock. History of malignancies, anticancer treatments, and clinical characteristics were prospectively collected.ResultsICU mortality was 48%. Diastolic dysfunction (e' ≤8 cm s(-1)) was an independent echocardiographic parameter associated with ICU mortality {odds ratio (OR) 7.7 [95% confidence interval (CI), 2.58-23.38]; P<0.001}. Overall, three factors were independently associated with ICU mortality: sepsis-related organ failure assessment score at admission [OR 1.35 ( 95% CI, 1.05-1.74); P=0.017], occurrence of diastolic dysfunction [OR 16.6 (95% CI, 3.28-84.6); P=0.001], and need for conventional mechanical ventilation [OR 16.6 (95% CI, 3.6-77.15); P<0.001]. Diastolic dysfunction was not associated with exposure to cardiotoxic drugs.ConclusionsEarly diastolic dysfunction is a strong and independent predictor of mortality in cancer patients presenting with septic shock. It is not associated with exposure to cardiotoxic drugs. Further studies incorporating monitoring of diastolic function and therapeutic interventions improving cardiac relaxation need to be evaluated in cancer patients presenting with septic shock.
