Background: N-terminal pro-brain natural peptide (NT-pro-BNP) is a well-established biomarker of tissue congestion and has prognostic value in patients with heart failure (HF). Nonetheless, there is scarce evidence on its predictive capacity for HF re-admission after an acute coronary syndrome (ACS). We performed a prospective, single-center study in all patients discharged after an ACS. HF re-admission was analyzed by competing risk regression, taking all-cause mortality as a competing event. Results are presented as sub-hazard ratios (sHR). Recurrent hospitalizations were tested by negative binomial regression, and results are presented as incidence risk ratio (IRR). Results: Of the 2133 included patients, 528 (24.8%) had HF during the ACS hospitalization, and their pro-BNP levels were higher (3220 pg/mL vs. 684.2 pg/mL; p < 0.001). In-hospital mortality was 2.9%, and pro-BNP was similarly higher in these patients. Increased pro-BNP levels were correlated to increased risk of HF or death during the hospitalization. Over follow-up (median 38 months) 243 (11.7%) patients had at least one hospital readmission for HF and 151 (7.1%) had more than one. Complete revascularization had a preventive effect on HF readmission, whereas several other variables were associated with higher risk. Pro-BNP was independently associated with HF admission (sHR: 1.47) and readmission (IRR: 1.45) at any age. Significant interactions were found for the predictive value of pro-BNP in women, diabetes, renal dysfunction, STEMI and patients without troponin elevation. Conclusions: In-hospital determination of pro-BNP is an independent predictor of HF readmission after an ACS.

Background: Posterior reversible encephalopathy syndrome (PRES) is characterized with magnetic resonance imaging (MRI) findings involving hyper-intense lesions in parieto-occipital regions of cerebral cortex and subcortex accompanying with neurological manifestations. Incidence of PRES was reported to vary 1.6-3.95% in children with childhood leukemia. Neurological findings differs from generalized seizures to limb hypo-aesthesia. Aims: The aim of this study was to demonstrate the characteristics' of PRES cases reported from ten centers in Turkey. Methods: The demographic and clinical features of PRES cases reported from ten centers were assessed with a questionnaire. A retrospective analysis of the findings was performed.

Background Coronary heart disease is chronic condition that usually has recurrent events. Risk factors for incident coronary heart disease are well known conditions related to recurrences have not been clearly outlined. Attributable risk proportion (ARP) refers to the proportion of incident cases in subjects exposed to risk factors that are attributable to that risk factor so we analysed ARP in wide cohort of patients admitted for an acute coronary syndrome (ACS). Methods Cross-sectional analysis of all patients admitted in two hospitals between January 2006 and December 2016. ARP was calculated by the equation: prevalence in exposed – (prevalence in exposed/odds ratio). LDL uncontrolled was codified as >70 mg/dl in patients with previous cardiovascular disease; >100 mg/dl in patients with diabetes without previous cardiovascular disease or; >155 mg/dl in patients without cardiovascular disease. Results We included 7,518 patients, mean age 66.9 (12.9) years, 72.5% males, median GRACE score 143.2 (40.3) and 35.3% STEMI. Previous coronary heart disease total was present in 2,032 (23.2%) patients and they had statistically higher mean age (70.6±11.11 vs. 65.8±13.3), prevalence of diabetes (37.9% vs. 25.3%) and hypertension (72.9% vs. 53.3%) and lower smoking habit (15.5% vs. 30.9%). LDLc was lower in patients with previous coronary heart disease (90.3±33.8 vs. 111.7±38.1; p<0.01), as well as HDLc (33.5±14.29 vs. 35.9±35.5; p<0.01) and haemoglobin (13.5±3.7 vs. 14.0±2.4; p<0.01). Uncontrolled LDLc was present in 83.4% of the patients with previous coronary heart disease, in contrast to the 28.7% of patients without previous coronary heart disease; this resulted in an ARP of 13.8%. The ARP for diabetes and hypertension were 1.6% and 1.4%, respectively. Conclusions The proportion of attributable risk of uncontrolled LDL on recurrent ACS is 13.8% and, therefore, 1 out of every 7 recurrent ACS could be prevented by an accurate LDLc control.
