|Left-sided Congestive Heart Failure|
Heart failure (HF) is a growing public health problem. While HF with deteriorated ejection fraction has faced numbers of (non) pharmacological advances, HF with preserved ejection fraction, which represents half of admission has today no efficient treatment.
Fibrosis is found in heart of patients with HF and preserved ejection fraction, is reponsible for stiff heart and has link to the transition to compensated/decompaseted HF and death.
The purpose of this work is to characterise myocardial fibrosis by any means to change the prognosis of patients with HF and preserved ejection fraction
Assessment of cardiac fibrosis by echocardiography (Speckle tracking), IRM (late-enhancement imaging), biology (markers of collagen turn-over) and proteomics
- - Inclusion Criteria: Male or female > 18 and < 85 years of age. Recent HF decompensation (framingham criteria, ejection fraction > 50% with 72 hours after admission and BNP > 100 ng/L or NT-proBNP > 300 ng/L), signed inform consent.
- - exclusion criteria: hypertrophic cardiomyopathy, restrictive cardiomyopathy, constrictive pericarditis, significant respiratory disease, pulmonary hypertension, core pulmonale, end-stage kidney disease, high cardiac output HF, isolated right ventricular dysfunction, pregnancy or child-bearing, biventricular pacing, No health insurance.
- - inclusion criteria: Male or female > 18 and < 85 years of age. signed inform consent. Health insurance.
- - exclusion criteria: significant ischemic heart disease, significant valvular heart disease, pericarditis, pulmonary hypertension, hypertrophic cardiomyopathy, restrictive cardiomyopathy, constrictive pericarditis, significant respiratory disease, pulmonary hypertension, core pulmonale, end-stage kidney disease, high cardiac output HF, isolated right ventricular dysfunction, pregnancy or child-bearing, biventricular pacing, No health insurance.
