[Current therapy of heart failure with mildly reduced or preserved left ventricular ejection fraction].
Based on the results of recent clinical trials investigating patients with heart failure and a mildly reduced (HFmrEF) or preserved (HFpEF) left ventricular ejection fraction, an update of the ESC guidelines on acute and chronic heart failure as well as the German `Nationale Versorgungsleitlinie Herzinsuffizienz' has been released. Consistently, they now recommend the use of SGLT2 inhibitors also in these patients' groups. ⋯ In patients with HFmrEF, intravenous application of iron can be considered to improve quality of life in iron-depleted patients. Patients experiencing a heart failure related hospitalization shall receive the foundational guideline-directed pharmacotherapy already while in hospital and undergo a timely post discharge visit to further optimize treatment.

[How to design a questionnaire? Practical tips on formulating the questions and constructing the questionnaire].
Questionnaires are often used in medical research, although the construction of questionnaires is not part of standard education for medical researchers. In this article, a step-by-step guide is given on how to formulate and use a questionnaire in practice. The steps are illustrated with an example. These instructions can help researchers to develop their own questionnaires in the context of their empirical research, which meet the quality standards of empirical social research.

HFrEF causes significant morbidity and mortality and represents a major public health burden. Recently, there have been significant scientific advances in the treatment of HFrEF, with ARNI, BB, MRA, and SGLT-2i forming the GDMT for HFrEF. ⋯ In addition, new initiation and titration procedures have recently been introduced that may progressively improve the management and prognosis of HFrEF. Further efforts are also needed to improve the use of GDMT, which is currently underutilized.

Heart 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. ⋯ 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.
