Critically ill patients with infective endocarditis, neurological complications and indication for cardiac surgery: a multicenter propensity-adjusted study.

ABSTRACT:

Background

The benefit-risk balance and optimal timing of surgery for severe infective endocarditis (IE) with ischemic or hemorrhagic strokes is unknown. The study aim was to compare the neurological outcome between patients receiving surgery or not.

Methods

In a prospective register-based multicenter ICU study, patients were included if they met the following criteria: (i) left-sided IE with an indication for heart surgery; (ii) with cerebral complications documented by cerebral imaging before cardiac surgery; (iii) with Sequential Organ Failure Assessment score ≥ 3. Exclusion criteria were isolated right-sided IE, in-hospital acquired IE and patients with cerebral complications only after cardiac surgery. In the primary analysis, the prognostic value of surgery in term of disability at 6 month was assessed by using a propensity score-adjusted logistic regression.

Results

192 patients were included including ischemic stroke (74.5%) and hemorrhagic lesion (15.6%): 67 (35%) had medical treatment and 125 (65%) cardiac surgery. In the propensity score-adjusted logistic regression, a favorable 6-month neurological outcome was associated with surgery (odds ratio 13.8 (95% CI 6.2-33.7). The 1-year mortality was strongly reduced with surgery in the fixed-effect propensity-adjusted Cox model (hazard ratio 0.18; 95% CI 0.11-0.27; p < 0.001). These effects remained whether the patients received delayed surgery (n = 62/125) or not and whether they were deeply comatose (Glasgow Coma Scale ≤ 10) or not.

Conclusions

In critically ill IE patients with an indication for surgery and previous cerebral events, a better propensity-adjusted neurological outcome was associated with surgery compared with medical treatment.

Project description:BackgroundNeurological complications are associated with poor outcome in patients with infective endocarditis (IE). Although guidelines recommend systematic brain imaging in the evaluation of IE patients, the association between early brain imaging findings and outcomes has never been evaluated in critically ill patients. We aimed to assess the association of CT-defined neurological complications with functional outcomes of critically ill IE patients.MethodsThis retrospective cohort study included consecutive patients with severe, left-sided IE hospitalized in the medical ICU of a tertiary care hospital. Patients with no baseline brain CT were excluded. Baseline CT-scans were classified in five mutually exclusive categories (normal, moderate-to-severe ischemic stroke, minor ischemic stroke, intracranial hemorrhage, other abnormal CT). The primary endpoint was 1-year favorable outcome, defined by a modified Rankin Scale score of 0-3.ResultsBetween 06/01/2011 and 07/31/2018, 156 patients were included. Among them, 87/156 (56%) had a CT-defined neurological complication, including moderate-to-severe ischemic stroke (n = 33/156, 21%), intracranial hemorrhage (n = 24/156, 15%), minor ischemic stroke (n = 29/156, 19%), other (n = 3/156, 2%). At one year, 69 (45%) patients had a favorable outcome. Factors negatively associated with favorable outcome in multivariable analysis were moderate-to-severe ischemic stroke (OR 0.37, 95%CI 0.14 - 0.95) and age (OR 0.94, 95%CI 0.91-0.97). By contrast, the score on the Glasgow Coma Scale was positively associated with favorable outcome (per 1-point increment, OR 1.23, 95%CI 1.08-1.42). Sensitivity analyses conducted in operated patients revealed similar findings. Compared to normal CT, only moderate-to-severe ischemic stroke was associated with more frequent post-operative neurological complications (n = 8/23 (35%) vs n = 1/46 (2%), p < 0.01).ConclusionModerate-to-severe ischemic stroke had an independent negative impact on 1-year functional outcome in critically ill IE patients; whereas other complications, including intracranial hemorrhage, had no such impact.

Project description:ObjectivesTo define the frequency and characteristics of acute neurologic complications in children hospitalised with infective endocarditis and to identify risk factors for neurologic complications.Study designRetrospective cohort study of children aged 0-18 years hospitalised at a tertiary children's hospital from 1 January, 2008 to 31 December, 2017 with infective endocarditis.ResultsSixty-eight children met Duke criteria for infective endocarditis (43 definite and 25 possible). Twenty-three (34%) had identified neurologic complications, including intracranial haemorrhage (25%, 17/68) and ischaemic stroke (25%, 17/68). Neurologic symptoms began a median of 4.5 days after infective endocarditis symptom onset (interquartile range 1, 25 days), though five children were asymptomatic and diagnosed on screening neuroimaging only. Overall, only 56% (38/68) underwent neuroimaging during acute hospitalisation, so additional asymptomatic neurologic complications may have been missed. Children with identified neurologic complications compared to those without were older (48 versus 22% ≥ 13 years old, p = 0.031), more often had definite rather than possible infective endocarditis (96 versus 47%, p < 0.001), mobile vegetations >10mm (30 versus 11%, p = 0.048), and vegetations with the potential for systemic embolisation (65 versus 29%, p = 0.004). Six children died (9%), all of whom had neurologic complications.ConclusionsNeurologic complications of infective endocarditis were common (34%) and associated with mortality. The true frequency of neurologic complications was likely higher because asymptomatic cases may have been missed without screening neuroimaging. Moving forward, we advocate that all children with infective endocarditis have neurologic consultation, examination, and screening neuroimaging. Additional prospective studies are needed to determine whether early identification of neurologic abnormalities may direct management and ultimately reduce neurologic morbidity and overall mortality.

Project description:BackgroundThe coagulation system is crucial in the pathogenesis of infective endocarditis and undergoes significant changes during course of the disease. However, little is known about the implications of those changes in the perioperative period. Aim of the present study was to delineate the specific coagulation patterns and their clinical consequence in patients undergoing cardiac surgery due to infective endocarditis.MethodsIn this single-centre, exploratory, prospective observational study, we investigated the incidence and degree of coagulopathy in patients with (n = 31) and without infective endocarditis (n = 39) undergoing cardiac valve surgery. The primary outcome was the differences between these two groups in rotational thromboelastometry (ROTEM) results before, during and after surgery. The secondary outcomes were the differences between the groups in heparin sensitivity, bleeding complications, and transfusion requirements.ResultsMost ROTEM parameters in EXTEM, INTEM and FIBTEM assays were significantly altered in patients with infective endocarditis. Clotting time in the EXTEM assay was significantly prolonged in the endocarditis group at all time-points, while all clot firmness parameters (A5, A10 and MCF) were significantly increased. The heparin sensitivity index was significantly lower in the endocarditis group (median index 0.99 vs 1.17s. IU-1.kg-1, p = .008), indicating increased heparin resistance. Patients with infective endocarditis had more bleeding complications as assessed by the universal definition of perioperative bleeding score (OR 3.0, p = .018), and more patients with endocarditis underwent early re-exploration (p = .018).ConclusionsThe findings of this exploratory investigation show significantly altered coagulation profiles in patients with infective endocarditis, with concomitant hyper- and hypocoagulability. Furthermore, the incidence of bleeding complications and transfusion requirements were increased in patients with endocarditis. These results show the potential of ROTEM to detect coagulation abnormalities in patients with infective endocarditis. Existing point-of-care coagulation testing guided algorithms for optimizing perioperative coagulation management possibly need to be adjusted for these high-risk patients undergoing cardiac surgery.
