    AbstractHeart failure with preserved ejection fraction (HFpEF) currently causes about half of the heart failure related hospitalizations. With the aging of the population and increasing prevalence of risk factors and comorbidities, such as arterial hypertension, diabetes mellitus and obesity, HFpEF prevalence is expected to increase as well. With regards to quality of life, overall morbidity, and mortality, HFpEF patients have a similarly adverse prognosis as patients with heart failure with reduced ejection fraction. The leading symptoms of exertional dyspnea and exercise intolerance with concomitant clinical signs of heart failure should, therefore, prompt diagnostic tests to exclude or confirm HFpEF. Considering the main pathophysiological mechanisms, echocardiography is crucial to non-invasively identify signs of left ventricular (LV) hypertrophy, impaired myocardial relaxation, and elevated filling pressures. Elevated NT-proBNP may furthermore indicate increased LV wall stress and volume overload. If the results of these investigations are inconclusive, parameters of elevated filling pressures can be measured invasively by right or left heart catheterization. High pulmonary capillary wedge pressure (PCWP) or left ventricular end-diastolic pressure (LVEDP) may confirm a HFpEF diagnosis. Ongoing studies are investigating potential distinct phenotypes within the HFpEF patient group.Thieme. All rights reserved.
