“…While our definition of myocardial injury artificially lowered the observed rate by excluding cases within 24 h of ICU admission and after AKI development), we still observed significant association between TWA-MAP < 65 mmHg and myocardial injury. However, it is possible that a raised troponin value is present in the absence of myocardial injury [27], although raised troponin values have been tied with myocardial injury within the septic population [28–31]. Our results of myocardial injury analysis should be interpreted with caution due to lack of universal troponin screening and diverse troponin tests employed among various U.S. Hospitals.…”

PurposeCurrent guidelines recommend maintaining a mean arterial pressure (MAP) ≥ 65 mmHg in septic patients. However, the relationship between hypotension and major complications in septic patients remains unclear. We, therefore, evaluated associations of MAPs below various thresholds and in-hospital mortality, acute kidney injury (AKI), and myocardial injury.MethodsWe conducted a retrospective analysis using electronic health records from 110 US hospitals. We evaluated septic adults with intensive care unit (ICU) stays ≥ 24 h from 2010 to 2016. Patients were excluded with inadequate blood pressure recordings, poorly documented potential confounding factors, or renal or myocardial histories documented within 6 months of ICU admission. Hypotension exposure was defined by time-weighted average mean arterial pressure (TWA-MAP) and cumulative time below 55, 65, 75, and 85 mmHg thresholds. Multivariable logistic regressions determined the associations between hypotension exposure and in-hospital mortality, AKI, and myocardial injury.ResultsIn total, 8,782 patients met study criteria. For every one unit increase in TWA-MAP < 65 mmHg, the odds of in-hospital mortality increased 11.4% (95% CI 7.8%, 15.1%, p < 0.001); the odds of AKI increased 7.0% (4.7, 9.5%, p < 0.001); and the odds of myocardial injury increased 4.5% (0.4, 8.7%, p = 0.03). For mortality and AKI, odds progressively increased as thresholds decreased from 85 to 55 mmHg.ConclusionsRisks for mortality, AKI, and myocardial injury were apparent at 85 mmHg, and for mortality and AKI risk progressively worsened at lower thresholds. Maintaining MAP well above 65 mmHg may be prudent in septic ICU patients.Electronic supplementary materialThe online version of this article (10.1007/s00134-018-5218-5) contains supplementary material, which is available to authorized users.

“…A more recent study has shown that sepsis-induced elevation in circulating histones was associated with cardiomyocyte damage, which resulted in elevated plasma cTnI levels (26). In addition, in patients with septic shock, cTnI levels were elevated and strongly correlated with cardiac dysfunction as evidenced by echocardiography (27). It was previously reported that there is a positive correlation between circulating histone levels and cTnI (12).…”

Background: Myocardial impairment is a major complication and an important prognostic predictor of sepsis. Therefore, early and accurate diagnosis as well as timely management of septic cardiomyopathy is critical to achieve favorable outcomes. Aims: To investigate the risk factors of septic cardiomyopathy. Study Design: Cross-sectional study Methods: This study performed between May 2016 and June 2018 recruited 93 septic patients from the intensive care unit. All patients received standardized treatments. Septic patients were divided into two groups: non cardiomyopathy (n=45) and septic cardiomyopathy group (n=48). Blood samples were collected and transthoracic echocardiography was performed within 24 hours of intensive care unit admission. Septic patients with one ultrasound abnormality but no history of heart disease were diagnosed as having septic cardiomyopathy. Plasma histones, cardiac troponin I, and N-terminal pro-brain natriuretic peptide were measured using ELISA. Sequential Organ Failure Assessment scores, vasopressor use, and the outcomes of intensive care unit stay were analyzed. Spearman rank analysis was used to determine the correlation between plasma histone H4 and other parameters. Binary logistic regression and receiver operating characteristic curve analysis were used to determine the risk factors for septic cardiomyopathy. Results: Compared with the non-cardiomyopathy group, the septic cardiomyopathy group had significantly higher plasma H4 and cardiac troponin I levels, a higher Sequential Organ Failure Assessment score, more frequent vasopressor use, and a higher mortality rate (p<0.05). Plasma histone H4 levels positively correlated with cardiac troponin I (r=0.577, p<0.001), N-terminal pro-brain natriuretic peptide (r=0.349, p=0.001), and Sequential Organ Failure Assessment scores (r=0.469, p<0.001). Binary logistic regression and receiver operating characteristic curve analyses revealed that elevated plasma histone H4 levels and vasopressor use were important risk factors for septic cardiomyopathy (p<0.05). Conclusion: Elevated plasma histone H4 levels could be used to predict septic cardiomyopathy in patients with sepsis.

Aim. To evaluate the dynamics and prognostic significance of serum N-terminal pro-B-type natriuretic peptide (NT-proBNP) level in patients with severe abdominal sepsis.Methods. We analysed survey data of 54 patients (28 men and 26 women) aged 64.5 years [56.25–78.00] with abdominal sepsis or septic shock. Disease severity scored according to the Acute Physiology and Chronic Health Evaluation II criteria was 16.3 ± 0.8 and according to the Sequential Organ Failure Assessment (SOFA) was 3 [3–6]. Statistical analysis of these data was performed using correlation analysis, logistic regression and receiver operating characteristic analysis.Results. Serum NT-proBNP level during the 1st week following admission to the intensive care unit (ICU) exceeded normal values, i.e. 2,570 [116.25–6,559.5] to 4,600 [1,680–18,200] pg/ml. At all disease stages, serum NT-proBNP level correlated with sepsis severity scores (SOFA), procalcitonin (PCT) levels, lactatemia, mean arterial pressure, heart rate and inotropic and vasoactive–inotropic scales (rho = 0.329–0.433; p < 0.02). On ICU days 3–4, serum NT-proBNP level of >5100 pg/ml was associated with increased risk of mortality [65.6%–88.2%; area under the curve (AUC) = 0.806; р < 0.0001]. Similarly, during this interval, elevated serum NT-proBNP level was associated with the use of inotropic drugs (OR = 1.0001, 95% CI = 1.000–1.0002, p < 0.0059). Notably, we found that 76.9%–79.0% of the patients with serum NT-proBNP level of >5250 pg/ml were receiving inotropic drugs including adrenaline, dopamine and dobutamine. We were unable to identify a specific association between serum NT-proBNP level and norepinephrine administration. On ICU days 7 and 8, among patients with serum NT-proBNP level of >3450 pg/ml, we observed a very close relationship between serum NT-proBNP level and PCT (sensitivity = 63.6%, specificity = 66.7%, AUC = 0.708; р = 0.0041).Conclusion. Serum NT-proBNP level is considerably elevated in patients with abdominal sepsis or septic shock. NT-proBNP level was associated with both traditional indicators of sepsis severity and indicators characterising the state of systemic circulation. Notably, serum NT-proBNP level correlates with cardiac failure and inotropic drug requirement. Although the mechanisms underlying the observed increases in serum NT-proBNP level remain unclear, the present findings indicate that this mediator is clearly a significant biomarker and predictor of adverse outcomes related to abdominal sepsis and septic shock.
