OBJECTIVES A treatment dilemma arises when surgery is indicated in patients with infective endocarditis (IE) complicated by stroke. Neurologists recommend surgery to be postponed for at least 1 month. This study aims to investigate the neurological complication rate and neurological recovery potential in patients with IE-related stroke. METHODS A total of 440 consecutive patients with left-sided IE undergoing surgery were investigated. During follow-up, neurological recovery was assessed using the modified Rankin scale and the Barthel index. Mortality was assessed with regression models adjusting for age. RESULTS The median follow-up time was 9.0 years. Patients with previous strokes were more likely to suffer from mitral valve endocarditis (29.5% vs 47.4%, P < 0.001). Symptomatic stroke was found in 135 (30.7%) patients; of them, 42 patients presented with complicated stroke (additional meningitis, haemorrhagic stroke or intracranial abscess). Driven by symptomatic stroke, the age-adjusted hospital mortality risk was 1.4-fold [95% confidence interval (CI) 0.74–2.57; P = 0.31] higher and the long-term mortality risk was 1.4-fold higher (95% CI 1.003–2.001; P = 0.048). Hospital mortality was higher in patients with complicated stroke (21.4% vs 9.7%; P = 0.06) only; however, mortality rates were similar comparing uncomplicated stroke versus no stroke. Among patients with complicated ischaemic strokes, the observed risk for intraoperative cerebral haemorrhage was 2.3% only and the increased hospital mortality was not driven by cerebral complications. In the long-term follow-up, full neurological recovery was observed in 84 out of 118 survivors (71.2%), and partial recovery was observed in 32 (27.1%) patients. Neurological recovery was lower in patients with complete middle cerebral artery stroke compared to other localization (52.9% vs 77.6%; P = 0.003). CONCLUSIONS Contrary to current clinical practice and neurological recommendations, early surgery in IE is safe and neurological recovery is excellent among patients with IE-related stroke.

OBJECTIVES Parental cardiovascular disease (CVD) is a known risk factor for premature CVD. It is unknown whether a positive family history (PFH) affects outcomes after coronary artery bypass grafting (CABG). METHODS Data come from a retrospective longitudinal study of CABG patients consecutively recruited from 2001 to 2018 (n = 5389). From this study, 2535 patients with premature CVD undergoing CABG under the age of 60 years and information on parental CVD were identified. The Framingham offspring study criteria were used to identify PFH of CVD. Multivariable Cox proportional hazards regression models were used to assess the effect of PFH on overall and major adverse cardiovascular and cerebrovascular event-free survival. RESULTS A total of 273 deaths and 428 major adverse cardiovascular and cerebrovascular events occurred during follow-up. PFH of CVD was found in 54.2% of patients (n = 1375). Within these patients, 66.1% had a father who experienced a premature cardiovascular event (n = 909), 27.8% a mother (n = 382) and 6.1% both a mother and a father (n = 84). In the majority of cases, the patient’s parent had experienced a cardiac event (85.9%, n = 1181) and 14.1% of patients with PFH reported parental stroke (n = 194). Following CABG, PFH was associated with improved overall [adjusted hazards ratio (HR) 0.67, 95% confidence interval (CI) 0.50–0.90; P = 0.008] and major adverse cardiovascular and cerebrovascular event-free survival (adjusted HR 0.73, 95% CI 0.68–0.89; P = 0.01). Among the covariates adjusted for age, diabetes, renal insufficiency, peripheral arterial disease, ejection fraction, previous cerebrovascular events and previous mediastinal radiation were all associated with poorer outcomes. CONCLUSIONS Although it is well established that a PFH increases the risk of requiring CABG at younger ages, this study shows that, paradoxically, PFH is also protective regarding long-term outcomes.
