The obtained results demonstrate that the high mortality can be caused by underlying diseases such as diabetes mellitus and high blood pressure, moderate Pulmonary Embolism Wells Score risk, platelet blood count less than 100000 (mcl), hypertension (HTN), high level of Bilirubin, smoking, and GCS level between 6 and 9.It is important to think about the eventual application of a COVID-19 vaccination certificate as an eligibility criterion to carry out certain activities and to discuss in advance the problems that the use of this tool may pose in legal terms. To this end, we must begin by stating the assumptions that would be necessary to justify its implantation, including scientific consensus on the scope of the immunity granted by COVID-19 vaccines, especially in blocking transmission in the community. Likewise, it emphasizes the importance of broadening the view in the sense of internalizing that the passport or vaccination pass constitutes only one of the many options within a rich catalog of possibilities when it comes to reinforcing the recommended vaccination model through incentives adopted in the Vaccination Strategy against COVID-19, including the use of nudging. In any case, if conditionality is installed and expanded to the extent of significantly influencing daily life, it could lead to a kind of indirect obligation, with the risk of dysfunctions in terms of equality and systemic coherence if the public powers do not contribute to clearly define the legal limits beforehand and to drive a process that in itself could be dispersed and disorderly.Coronary chronic total occlusion (CTO) produces an important clinical problem, often treated with medical therapy or coronary artery bypass grafting. Recent clinical studies, both registries and randomized trials, demonstrated that percutaneous coronary interventions (PCI), could provide a valid therapeutic option. Nonetheless, significant reduction in all-cause mortality, cardiac mortality, myocardial infarction, MACE, and MACCE has not been demonstrated in the subgroups analysis of randomized trials. These analyses suggest that PCI for CTO should be reserved for patients with angina or with large areas of the myocardium with reversible ischaemia. Large randomized studies should search for a personalized approach, considering the risks and complexity of PCI in CTO, which should mainly consider the extension of the ischaemia and the viability of the myocardium.Sudden cardiac death results from arrhythmias commonly caused by channelopathies and cardiomyopathies, often due to several genetic factors. An emerging concept is that these disease states may in fact overlap, with variants in traditionally classified 'cardiomyopathy genes' resulting in 'channelopathies phenotypes'. Another important concept is the influence of both genetic and non-genetic factors in disease expression, leading to the utilization of systems biology approaches, such as genomics/epigenomics, transcriptomics, proteomics, metabolomics, lipidomics, and glycomics, to understand the disease severity and progression and to determine the prognosis and the best course of treatment. OSI-930 datasheet In fact, our group has discovered significant differences in metabolites, proteins, and lipids between controls and Brugada syndrome patients. Omics approaches are useful in overcoming the dogma that both channelopathies and cardiomyopathies exist as Mendelian disorders (caused by a mutation in a single gene). This shift in understanding could lead to new diagnostic and therapeutic approaches.Antiplatelet agents represent one of the cornerstones of drug therapy for acute coronary syndromes (ACS). In the last decade, the arrival of prasugrel and ticagrelor, faster and more powerful oral platelet receptor P2Y12 inhibitors compared to clopidogrel, significantly improved platelet inhibition in patients with ACS. However, the reduction of thrombotic risk came at the cost of increased bleeding risk. Despite having similar indications, prasugrel and ticagrelor have different characteristics and methods of use, essentially due to a different design of the trials in which they have been studied. The optimal use of these antiplatelets in clinical practice should therefore be tailored in individual patients. In the acute phase of ACS with high thrombotic burden, all oral P2Y12 inhibitors have limitations, mainly due to the delay of onset of action related to oral administration. In this scenario, parenteral antiplatelet agents (glycoprotein inhibitors IIb/IIIa and cangrelor) may play a key role in case of percutaneous coronary interventions of high thrombotic coronary lesions and in the prevention of early thrombotic complications. Cangrelor, an intravenous inhibitor of the P2Y2 receptor, has peculiar pharmacokinetic and pharmacodynamic characteristics that make it particularly suitable to be used as an antiplatelet during coronary angioplasty as it achieves a rapid and powerful antiplatelet effect in patients not pretreated with oral medications, and has a favourable safety profile in relation to the bleeding risk.Secondary mitral insufficiency (SMI) is caused by dilatation and left ventricular dysfunction and is a frequent finding in patients with heart failure (HF). It is associated with a mortality of between 40% and 50% at 3 years. The first-line treatment is represented by medical therapy, possibly associated, when indicated, with cardiac re-synchronization. If the patient remains symptomatic, corrective action should be considered. Surgery is indicated in cases of severe SMI with ejection fraction >30% and the need for myocardial revascularization. The management of patients in whom revascularization is not an option remains extremely complex and the evidence in this field is extremely limited. Percutaneous transcatheter therapies, reparative or replacement, are rapidly emerging as valid alternatives in cases of patients at high surgical risk. In particular, edge-to-edge repair (MitraClip) has proven effective in improving symptoms and reducing hospitalizations for HF. However, neither transcatheter nor surgical mitral repair or replacement has been shown to significantly improve prognosis, with mortality remaining high (14-20% at 1 year). Randomized trials aimed at assessing the effect of these treatments and establishing their long-term outcomes are urgently required.
