Background. There are few studies about post myocardial infarction follow-up using telemedicine. We organized a post-discharge telemedicine service with a dedicated team. To do this, it was necessary that all stakeholders involved in the organization and use of the telemedicine service were properly educated and informed. Methods. We designed a theoretical–practical mini-course to train healthcare personnel and increase skills, with excellent learning outcomes and satisfaction. Thereafter, we enrolled patients affected by acute myocardial infarction with ST elevation (STEMI), MINOCA (myocardial infarction with no obstructive coronary atherosclerosis), Takotsubo syndrome or spontaneous coronary dissection, and high-risk acute myocardial infarction without ST elevation (NSTEMI). At discharge, the cardiology technician performed counselling for the patient, using regional platforms, such as televisit, at 1 and 4 months, allowed us to monitor major adverse cardiac events (MACE), heart failure, arrhythmias, unstable angina and non-cardiovascular events, therapy adherence, target therapy and customer satisfaction. Results. Between November 2021 and February 2023, we enrolled 110 patients: 72% affected by STEMI, 22% by NSTEMI. At the 1-month follow up, 12 patients did not reach the pressure target and 23 patients did not reach the LDL target. We observed three patients requiring hospital readmission, three requiring hospital visits for further investigation, and one death. To date, a four month follow up was performed for 54 patients. No readmissions or deaths occurred. We detected a rate of 96% of customer satisfaction. Conclusions. A health coordination center with a dedicated team makes televisit safe as a follow-up for post-myocardial infarction patients. Beforehand, it is fundamental for healthcare professionals to acquire theoretical knowledge and updates, and the acquisition of manual, technical and practical skills. Full article

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes coronavirus disease 2019 (COVID-19), which was classified as a pandemic in March 2020. As of 22 January 2022, globally more than 347 million cases of COVID-19 have been diagnosed, with 5.6 million deaths, making it the deadliest pandemic since the influenza pandemic in 1918. The clinical presentation of COVID-19-related illness spans from asymptomatic to mild respiratory symptoms akin to influenza infection to acute symptoms, including pneumonia necessitating hospitalisation and admission to intensive care units. COVID-19 starts in the upper respiratory tract and lungs but in severe cases can also involve the heart, blood vessels, brain, liver, kidneys and intestine. The increasing global health and economic burden of COVID-19 necessitates an urgent and global response. Understanding the functional characteristics and cellular tropism of SARS-CoV-2, and the pathogenesis that leads to multi-organ failure and death, has prompted an unprecedented adoption of organoid models. Successful drug discovery and vaccine development rely on pre-clinical models that faithfully recapitulate the viral life cycle and the host cell response to infection. Human stem cell-derived organoids fulfill these criteria. Here we highlight the role of organoids in the study of SARS-CoV-2 infection and modelling of COVID-19 pathogenesis. Full article

Takotsubo cardiomyopathy is rapidly reversible heart failure syndrome that usually mimics the symptoms of acute myocardial infarction with the characteristic regional wall-motion abnormalities (classically with a virtual apical ballooning caused by hypokinetic or akinetic apical or midventricular myocardium and hypercontraction of the basal segments) and absence of obstructive coronary artery disease. TC is usually associated with identifiable emotional, psychological or physical stress event and most commonly appears in postmen- opausal women. The certain pathophysiological mechanism remains unknown. However, the central hypothesis is supported by the excess of catecholamines and hyperactivity of nervous system. In the last decades the frequency of the TC diagnosis is increasing rapidly but at the initial presentation the diagnosis remains challenging due to the close similarities between TC and ST elevation myocardial infarction clinical presentations that consider TC as an important part of differential diagnosis in acute coronary syndrome.
