Atrial fibrillation and heart failure with preserved left ventricular (LV) ejection fraction (HFpEF) are of high importance in cardiology due to the increasing number of cases. Both diseases can mutually affect each other and important cardiovascular risk factors, e.g. arterial hypertension, diabetes mellitus, obesity and chronic renal insufficiency can be observed with increasing frequency. Currently proven treatment concepts for patients with heart failure and reduced ejection fraction (HFrEF) do not appear to have a comparable prognostic or symptomatic benefit for patients with HFpEF. ⋯ Also, heart and kidney function are negatively affected by atrial fibrillation. Retrospective analyses of patients with HFpEF and atrial fibrillation who had been treated by pulmonary vein isolation could show that interventional treatment of the atrial fibrillation led to an improvement in the New York Heart Association (NYHA) stage and diastolic function. Currently running prospective randomized clinical trials, such as the AMPERE study including patients with HFpEF and atrial fibrillation undergoing pulmonary vein isolation, will hopefully provide reliable prospective randomized data and possibly show an improved symptom control and perhaps also prognostically relevant treatment for HFpEF patients with atrial fibrillation.

[Heart failure care in a digitalized future : A discourse on resource-sparing structures and self-determined patients].
Digital health solutions, applications of artificial intelligence (AI) and new technologies, such as cardiac magnetic resonance imaging and cardiac human genetics are currently being validated in cardiac healthcare pathways. They show promising approaches for improving existing healthcare structures in the future by strengthening the focus on predictive, preventive and personalized medicine. In addition, the accompanying use of digital health applications will become increasingly more important in the future healthcare, especially in patients with chronic diseases. ⋯ Since HF is frequently accompanied by various comorbidities during the course of the disease that are often recognized only after a delay, the necessity for a timely simultaneous and preventive treatment of multiple comorbidities in cardiovascular diseases is emphasized. Against this background the currently separately applied disease management programs (DMP) are critically questioned. The development of a holistic DMP encompassing all indications for the treatment of chronic diseases may pave the way to a more efficient medical care system.

Heart failure with preserved ejection fraction (HFpEF) is a heterogeneous syndrome with diverse underlying etiologies and pathophysiological factors. Obesity and type 2 diabetes mellitus (T2DM), diseases which frequently coexist, induce a cluster of metabolic and nonmetabolic signaling derangements, which promote induction of inflammation, fibrosis and myocyte stiffness, all representing hallmarks of HFpEF. ⋯ Obese patients with HFpEF therefore belong to a unique HFpEF phenotype with a particularly poor prognosis that could benefit from an EAT-oriented phenotype-specific intervention. In addition to statins and antidiabetic drugs such as metformin, glucagon-like peptide‑1 (GLP-1) receptor agonists and sodium-glucose transporter 2 (SGLT-2) inhibitors could also play an important role.

Thrombotic complications following coronary interventions (PCI) used to be frequent specifically in acute coronary syndrome (ACS) patients. In recent years complication rates have significantly fallen due to improved stent technology, catheterisation techniques and intravascular visualisation. Therefore, the shortest necessary duration of dual antiplatelet therapy (DAPT) comprising aspirin and a P2Y12 inhibitor is constantly the subject of scientific investigations in order to avoid bleeding complications without allowing ischemic complications to occur. ⋯ In the meantime, reduced-duration DAPT of 3-6 months is being recommended for most patients. Recent data show that in patients with a high bleeding risk, a DAPT treatment period of 4 weeks may be sufficient with a markedly reduced rate of bleeding and without evidence for more ischemic events. Following the early termination of DAPT, continuing antithrombotic monotherapy with the P2Y12 inhibitor ticagrelor may be indicated to prevent further ischemic events without the risk of bleeding complications comparable to DAPT.

Heart failure and renal insufficiency as well as pulmonary hypertension are pathophysiologically closely associated as a cardio-renal or cardio-pulmonary-renal syndrome. Due to the frequent hospitalization of patients affected by this syndrome, it is of high medical and also health economic relevance. Besides the inhibition of the renin-angiotensin-aldosterone system (RAAS), multimodal treatment options are available with mineralocorticoid receptor antagonists, angiotensin receptor-neprilysin inhibitors and sodium-glucose transporter 2 (SGLT-2) inhibitors. Profound knowledge of the pathophysiology and the therapeutic options is as necessary for an optimized medical care as patient-oriented, transdisciplinary and cross-sectoral care.
