AimsThe prevalence of cardiovascular and non-cardiovascular co-morbidities and their relative importance for outcomes in heart failure with preserved ejection fraction (HFPEF) remain poorly characterized. This study aimed to investigate this. %26lt;br%26gt;Methods and resultsThe Karolinska-Rennes (KaRen) Study was a multinational prospective observational study designed to characterize HFPEF. Inclusion required acute HF, defined by the Framingham criteria, LVEF 45%, and NT-pro-BNP 300ng/L or BNP 100ng/L. Detailed clinical data were collected at baseline and patients were followed prospectively for 18 months. Predictors of the primary (HF hospitalization or all-cause mortality) and secondary (all-cause mortality) outcomes were assessed with multivariable Cox regression. A total of 539 patients [56% women; median (interquartile range) age 79 (72-84) years; NT-pro-BNP/BNP 2448 (1290-4790)/429 (229-805) ng/L] were included. Known history of HF was present in 40%. Co-morbidities included hypertension (78%), atrial fibrillation/flutter (65%), anaemia (51%), renal dys46%), CAD (33%), diabetes (30%), lung disease (25%), and cancer (16%). The primary outcome occurred in 268 patients [50%; 106 deaths (20%) and 162 HF hospitalizations (30%)]. Important independent predictors of the primary and/or secondary outcomes were age, history of non-cardiovascular syncope, valve disease, anaemia, lower sodium, and higher potassium, but no cardiovascular co-morbidities. Renin-angiotensin system antagonist and mineralocorticoid receptor antagonist use predicted improved prognosis. %26lt;br%26gt;ConclusionHFPEF was associated with higher age, female gender, hypertension, atrial fibrillation/flutter, and numerous non-cardiovascular co-morbidities. Prognosis was determined by non-cardiovascular co-morbidities, but use of conventional heart failure medications may still be associated with improved outcomes.
