Non-alcoholic fatty liver disease (NAFLD) is a spectrum of fat-associated liver conditions that increase risk of cardiovascular disease and mortality. The diagnosis and clinical management of NAFLD remain a challenge for cardiologists. Our group performed a systematic review in PubMed of the relationship between NAFLD and cardiovascular disease, identifying 35 relevant articles. NAFLD is likely to be the liver’s expression of metabolic syndrome and increases the risk of several cardiovascular diseases, including coronary artery disease, stroke, heart failure and electrical disorders, and chronic kidney disease. Echocardiography is a useful tool to check early subclinical abnormalities in heart structure and function linked to NAFLD progression, such as cardiac diastolic impairment or epicardial fat thickness. Currently, NAFLD is predominantly managed by lifestyle changes with the aim of weight loss, based on the Mediterranean diet and intense exercise training. Despite the lack of approved drugs for NAFLD, new potential treatments, mainly glucagon-like peptide-1 agonists or sodium–glucose cotransporter 2 inhibitors, could change cardiologists’ approach to this pathology.
Echocardiographic myocardial strain is crucial for early detection of anthracycline-induced cardiotoxicity, particularly in patients at moderate or high risk. Background/Objectives: This study investigates changes in global longitudinal strain (GLS) in breast cancer patients with low baseline risk for cardiotoxicity during cancer therapy. We also examined the relationship between echocardiographic strain, structural myocardial changes, and microRNA (miRNA) dysregulation associated with cancer treatment using an animal model. Methods: Echocardiography and blood tests were examined in 33 breast cancer patients with low baseline risk for cardiotoxicity during anthracycline treatment, with a follow-up at 12 months. Additionally, 16 Wistar rats received epirubicin (20 mg/kg over 4 weeks) to examine cardiac strain and structural changes. Moreover, circulating miRNA levels were assessed in patients’ serum using microarray at the end of the treatment and further analyzed in peripheral blood from the animal model. Results: Pathological GLS values were observed in 27.27% of patients after four cycles, with 15.15% showing reduced left ventricular ejection fraction (LVEF) after 12 months. In the animal model, epirubicin-induced circumferential strain (CS) decrease correlates with myocardial fibrosis assessed histologically and by a significant increase in COL1 and TGFB2 expression. Furthermore, we found a significant decrease in aquaporin1 expression associated with the presence of vacuoles in treated rats. Furthermore, dysregulation in the expression of miRNAs was observed in patients with cardiotoxicity. Among them, hsa-miR-122-5p is increased in both patient and rat serum post-treatment. Conclusions: A notable percentage of low-risk patients exhibited cardiac strain reduction due to cardiotoxicity. Epirubicin treatment caused structural heart changes in rats, highlighting miR-122-5p as a potential fibrosis marker that correlated with echocardiographic parameters.

Introduction: Different organizations have recommended changes in life support in the COVID-19 pandemic, just when maintaining the competence in cardiopulmonary resuscitation is compromised because on-site training must be avoided. We developed a pilot teaching-learning experience to promote cardiopulmonary resuscitation skills acquisition in this situation. The aim of this study was to describe that tool and to analyze its usefulness. Methods: The experience consisted of three phases: first, reviewing the scientific literature; second, defining written local recommendations and recording a short video simulating the initial attention to a cardiac arrest in this COVID-19 context; third, creating a test to be answered by hospital health professionals. Results: The final sample was 121 subjects; 66.1% were women; the mean age was 45.8 years (SD = 10.24). Among them, 43% were doctors, 43% nurses, 4.1% nursing assistants, and 9.9% others. 89.3% participants had received prior training in life support. In the test, questions 1, 2, 5, 6, 7, and 8 were answered correctly by more than 80%; questions 3 and 4 were answered correctly by 57.9% and 41.3%, respectively. All participants expressed that the video helped them to refresh their knowledge and skills in life support. Discussion: When on-site training is not possible, distance learning—as in our teaching-learning innovation because of the COVID-19 pandemic—may be a valid option to acquire/refresh cardiopulmonary resuscitation skills.
