Alzheimer's disease (AD) is the most common cause of dementia. The number of people affected will increase dramatically in the coming decades due to the demographic change. Causal pharmacological approaches have not been available to date. The monoclonal anti-amyloid beta antibody aducanumab was recently approved for the treatment of AD in the USA but was rejected in Europe in December 2021 by the European Medicines Agency (EMA). ⋯ Anti-amyloid antibodies represent the first cause-based, disease-modifying therapy for AD approved in the USA. Compared to the near-complete removal of cerebral amyloid plaques, the magnitude of the clinical effect is smaller and the benefit for patients is currently subject to controversial discussions. Nonetheless, the new treatment option represents an important step in the development of effective treatment. Future strategies for the treatment of AD will likely aim at a multimodal concept with different molecular targets. A prerequisite for all effective disease-modifying therapies will be an early biomarker-based diagnosis prior to the onset of a dementia-type syndrome.

In August 2021, an update of the European Society of Cardiology-Heart Failure Association guideline for the diagnosis and treatment of heart failure was released. To review the changes implied by current guidelines regarding the diagnosis and treatment of patients with heart failure and preserved left ventricular ejection fraction (HFpEF). The diagnosis of HFpEF requires the combined presence of clinical signs, left ventricular ejection fraction ≥ 50%, elevated natriuretic peptides, and elevated left ventricular filling pressure. ⋯ It is expected that this finding will become part of updated treatment recommendations in the near future. Although challenging, the early diagnosis of HFpEF is key to averting the poor prognosis associated with this frequent condition. Multidisciplinary care and innovative pharmacologic and non-pharmacologic therapies, however, can improve quality of life, exercise tolerance, and prognosis.

Since 2020 physicians can prescribe digital health applications (DiGA), also colloquially known as apps on prescription, which are reimbursed by the statutory health insurance when they are approved by the Federal Institute for Drugs and Medical Devices (BfArM) and are included in the DiGA Ordinance. Currently, there is one approved DiGA (indication obesity) for internal medicine. ⋯ The DiGA are innovative new means, which maybe support internal medicine physicians in the diagnostics and treatment in the future. The benefits in this field of indications are limited by unclarified issues, especially on the prescription practice and the currently low number of DiGA available in internal medicine.

Since the current guidelines were published in 2018, a total of 5 sham-controlled high-quality studies evaluating renal denervation have been conducted and the results were published. These five studies clearly confirmed the efficacy and safety of renal denervation, which correspond to the knowledge of the Clinical Consensus Conference. Thus, an update of the guidelines for the treatment of arterial hypertension regarding the clinical significance of renal denervation is urgently necessary. ⋯ It is the task of the treating physician to provide the patient with the ideal treatment concept. Clearly, renal denervation will not replace antihypertensive pharmacotherapy; however, it can lead to a reduction of the drug burden and increase of patient adherence to medication. It represents an option of modern antihypertensive treatment and will also become increasingly more important in special patient groups.

Mobile health (mHealth) for the detection of atrial fibrillation is an innovative domestic monitoring of the heart rhythm. The use of mHealth in the context of atrial fibrillation increases the availability of diagnostic technologies and facilitates the integration into telemedical treatment concepts as well as the active participation of patients in the treatment process. The detection of atrial fibrillation with mHealth applications is usually based on electrocardiography (ECG) or by detection of the pulse wave using photoplethysmography (PPG). ⋯ Nevertheless, at present mHealth is only integrated to a limited extent into the reality of patient care. Adequate reimbursement and medical remuneration as well as opportunities to derive information and qualification are prerequisites in order to be able to guarantee a comprehensive implementation in the future. The Digital Health Care Act passed in 2019, regulates the reimbursement of digital healthcare applications but issues of primary preventive applications have not yet been included.
