Inclusion criteria

Inclusion criteria: Study group: -Left ventricular ejection fraction with LVEF >40% -heart failure symptoms NYHA= II AND left ventricular diastolic dysfunction / raised filling indices according to current AHA-recommendation (Nagueh et al 2025) - stepwise diagnostic procedure - STEP1 (diminished LV Relaxation) : e´septal =6,5 cm/s - STEP2 (LA/LV remodeling and raised LA-pressure E/e´mean>14, LARS =2, LAVI > 34 ml/m2 (except in athletes, anemia, atrial fibrillation/ atrial flutter or mitral valve disease) - LV mass index >95 g/m2 in women or 115 g/m2 in men - Characterisation as diastolic dysfunktion if a) STEP1 is present AND at least 1 finding in STEP2 OR b) STEP1 not present but >=2 findings of STEP2 present - optional an exercise stress echocardiography can be performed if dyspnea ist present an unclear left ventricular filling pressure (inclusion if E/e´ ratio mean >=14 (or E/e´septal >=15) and peak TR velocity >=3,2 m/s during or 1-2 minutes after exercise -stable medication for at least 4 weeks prior to inclusion (antihypertensive medication, diuretics, statins) -written informed consent Comparison group: -at least one cardiovascular risk factor (hypertension, type II diabetes without insulin therapy, chronic obstructive lung disease, chronic kidney disease without dialyis, BMI 27kg/m2 -normal systolic and diastolic left ventricular function in echocardiogram -normal ankle-brachial-index -exclusion of atherosclerotic plaques in duplex ultrasound of carotid artery -stable medication for at least 4 weeks prior to inclusion (antihypertensive medication, diuretics, statins) -written informed consent

Exclusion criteria

Exclusion criteria: -acute cardiac decompensation in the last 4 weeks prior to inclusion -active infectious disease in the last 4 weeks prior to inclusion -myocardial infarction (STEMI or NSTEMI) in the past 2 months -cardiac surgery oder cardiac intervention in the past 2 months -other major surgery in the past 2 months -percardial disease (if hemodynamic relevant) -recovered LVEF after previous reduced ejection fraction (HFrEF) -known cardiomyopathy -severe valvular heart disease with planned intervention -severe pulmonary hypertension -pregnancy -study visit after one year not feasible -active cancer for subgroup MRI: -common contraindications for MRI (not-MRI-suitable implants, claustrophobia, severe renal function impairment [eGFR <30 ml/min/1.73m2]) -study specific contraindications for MRI: permanent atrial fibrillation, implanted pacemaker/ defibrillator for eye examination: -common contraindiction for the use of mydriatic drug (narrow angle glaucoma)

Design outcomes

Primary

MeasureTime frame
Aim of this cohort study is to identify subgroups of patients with heart failure with preserved or mildly reduced ejection fraction (HFpEF/ HFmrEF) to allow a better characterisation of the disease and develop individualized therapeutic concepts that can be evaluated in pilot studies. A comparison group will be recruited with participants that show risk factors for cardiovascular disease but have no heart failure manifestation.
