Heart failure (HF) is a common complication of various cardiac diseases, and its incidence constantly increases. This is caused mainly by aging of populations and improvement in the treatment of coronary artery disease. As HF patients age, they tend to develop comorbidities, creating new problems for health-care professionals. Sarcopenia, defined as the loss of muscle mass and function, and cachexia, defined as weight loss due to an underlying illness, are muscle wasting disorders of particular relevance in the heart failure population, but they go mostly unrecognized. The coexistence of chronic HF and metabolic disorders facilitates the development of cachexia. Cachexia, in turn, significantly worsens a patient’s prognosis and quality of life. The mechanisms underlying cachexia have not been explained yet and require further research. Understanding its background is crucial in the development of treatment strategies to prevent and treat tissue wasting. There are currently no specific European guidelines or recommended therapy for cachexia treatment in HF (“cardiac cachexia”).

We are constantly looking for new parameters and markers that can help in the assessment of patients with various diseases, including cardiac disorders; this can translate into better care and improved prognosis. Suppression of tumorigenicity 2 (ST2) has recently gained interest as a potential biomarker in many fields: it is involved in many inflammatory diseases and allergies, including asthma, rheumatoid arthritis and inflammatory bowel disease, and it participates in cardiovascular pathophysiology. Suppression of tumorigenicity 2 is being investigated as a promising biomarker in heart diseases. The interaction of interleukin 33 (IL-33) and ST2L is part of a cardioprotective pathway that prevents fibrosis and inhibits inflammatory response, hypertrophy and apoptosis of cardiomyocytes. In this review, we try to summarize the current knowledge about the usefulness of soluble ST2 (sST2) in cardiology. Clinical data show promising results for the possibility of using sST2 in various diseases, such as arrhythmia, hypertension, myocarditis, acute aortic syndrome, and coronary artery disease (CAD). This novel biomarker may also play a role in heart transplantation and perioperative care.

Cardiovascular diseases (CVD) affect 60% of people over 60 years of age and are one of the main causes of death in the world. Diagnosed cardiovascular disease also triples the likelihood of Frailty syndrome (FS). FS has become increasingly relevant in cardiology and cardiac surgery and occurs in a significant number of patients with CVD, with prevalence ranging from 25% to 62%. Viewed in a multidimensional, biopsychosocial perspective, FS increases a patient’s vulnerability, making them susceptible to several adverse clinical outcomes. Frailty syndrome also is a predictor of mortality in patients with CVD regardless of age, severity of disease, multi-morbidity, and disability. Frailty syndrome potentially can be prevented in patients with CVD and its early identification is important to avoid the development of disability, dependence on others and reduced quality of life. The aim of this paper is to show the relationship between FS and specific CVDs (coronary artery disease, hypertension, atrial fibrillation, heart failure) and cardiac procedures (device implantation, cardiac surgery, and transcatheter aortic valve implantation). Furthermore, we highlight those areas that require further research to fully understand the relationship between FS and CVD and to be able to minimize or prevent its adverse effects.

The incidence of both diabetes mellitus type 2 and heart failure is rapidly growing, and the diseases often coexist. Sodium-glucose co-transporter 2 inhibitors (SGLT2i) are a new antidiabetic drug class that mediates epithelial glucose transport at the renal proximal tubules, inhibiting glucose absorption—resulting in glycosuria—and therefore improving glycemic control. Recent trials have proven that SGLT2i also improve cardiovascular and renal outcomes, including reduced cardiovascular mortality and fewer hospitalizations for heart failure. Reduced preload and afterload, improved vascular function, and changes in tissue sodium and calcium handling may also play a role. The expected paradigm shift in treatment strategies was reflected in the most recent 2021 guidelines published by the European Society of Cardiology, recommending dapagliflozin and empagliflozin as first-line treatment for heart failure patients with reduced ejection fraction. Moreover, the recent results of the EMPEROR-Preserved trial regarding empagliflozin give us hope that there is finally an effective treatment for patients with heart failure with preserved ejection fraction. This review aims to assess the efficacy and safety of these new anti-glycemic oral agents in the management of diabetic and heart failure patients.

Purpose: Atrial fibrillation (AF) is the most common cardiac arrhythmia, and its incidence increases with age. The elderly population is commonly affected by frailty syndrome (FS). FS syndrome along with anxiety and depressive symptoms are prevalent among elderly patients with AF. It is unclear whether depression contributes to AF or vice versa. The purpose of this study was to assess correlations between FS and the occurrence of anxiety and depression symptoms in a group of elderly patients with AF. Patients and Methods: This cross-sectional study included 100 elderly patients (69 females, 31 males, mean age: 70.27 years) with AF. Standardized research instruments were used including the Tilburg Frailty Indicator (TFI) to assess FS, and two questionnaires to assess depression including the Geriatric Depression Scale (GDS), and the Hospital Anxiety Depression Scale (HADS). Results: Mild FS was found in 38% and moderate FS in 29% of patients. Based on GDS scores, depression symptoms were found in 51% of patients’ sample. Based on HADS scores, 20% of patients were found to have anxiety symptoms, and 28% revealed depression symptoms. Single-factor analysis demonstrated a significant positive correlation between HADS anxiety symptoms (r=0.492), HADS depression symptoms (r=0.696), and GDS score (r=0.673) on the one hand, and overall TFI frailty score on the other. Multiple-factor analysis identified overall GDS score, education, and lack of bleeding as significant independent predictors of TFI scores (p< 0.05). Conclusion: FS is common in the population of elderly patients with AF. We found evidence for the association between symptoms of anxiety and depression and the incidence of FS in this group of patients. Due to the risk of consequences which may in part be irreversible, screening for FS is recommended.
