Aim: Echo‐derived haemodynamic classification, based on forward‐flow and left ventricular (LV) filling pressure (LVFP) correlates, has been proposed to phenotype patients with heart failure and reduced ejection fraction (HFrEF). To assess the prognostic relevance of baseline echocardiographically defined haemodynamic profile in ambulatory HFrEF patients before starting sacubitril/valsartan. Methods and results: In our multicentre, open‐label study, HFrEF outpatients were classified into 4 groups according to the combination of forward flow (cardiac index; CI:< or ≥2.0 L/min/m2) and early transmitral Doppler velocity/early diastolic annular velocity ratio (E/e′: ≥ or <15): Profile‐A: normal‐flow, normal‐pressure; Profile‐B: low‐flow, normal‐pressure; Profile‐C: normal‐flow, high‐pressure; Profile‐D: low‐flow, high‐pressure. Patients were started on sacubitril/valsartan and followed‐up for 12.3 months (median). Rates of the composite of death/HF‐hospitalization were assessed by multivariable Cox proportional‐hazards models. Twelve sites enrolled 727 patients (64 ± 12 year old; LVEF: 29.8 ± 6.2%). Profile‐D had more comorbidities and worse renal and LV function. Target dose of sacubitril/valsartan (97/103 mg BID) was more likely reached in Profile‐A (34%) than other profiles (B: 32%, C: 24%, D: 28%, P < 0.001). Event‐rate (per 100 patients per year) progressively increased from Profile‐A to Profile‐D (12.0%, 16.4%, 22.9%, and 35.2%, respectively, P < 0.0001). By covariate‐adjusted Cox model, profiles with low forward‐flow (B and D) remained associated with poor outcome (P < 0.01). Adding this categorization to MAGGIC‐score and natriuretic peptides, provided significant continuous net reclassification improvement (0.329; P < 0.001). Intermediate and high‐dose sacubitril/valsartan reduced the event's risk independently of haemodynamic profile. Conclusions: Echocardiographically‐derived haemodynamic classification identifies ambulatory HFrEF patients with different risk profiles. In real‐world HFrEF outpatients, sacubitril/valsartan is effective in improving outcome across different haemodynamic profiles. [ABSTRACT FROM AUTHOR]

Anorexia nervosa (AN) is an eating disorder in which a distorted self-perception of body image and an excessive fear of gaining weight result in extreme restrictions in eating habits. AN may be divided into two types: a 'binge-eating/purging type' during which the individual regularly engages in overeating and then purging behavior, and a 'restricting type', in which she does not. AN is a serious medical problem in young people in Western societies. It is widely reported that patients with AN exhibit an enhanced mortality rate as compared with age-matched healthy subjects, which has been mainly ascribed to cardiac complications. At least one-third of all deaths in patients with anorexia nervosa are estimated to be due to cardiac causes, mainly sudden death. Cardiovascular complications of AN can be present in up to 80 % of cases, and among them alterations in cardiac electrical activity, structure and hemodynamics have been reported as causes of morbidity and mortality. The objective of this brief review is to summarize current knowledge on the main cardiovascular complications of AN, their underlying mechanisms and the possible therapeutic approaches.
