These changes are mainly due to the malfunction or abnormalities of cardiomyocytes. Similar to non-cirrhotic heart failure, cardiomyocytes in cirrhotic cardiomyopathy demonstrate a variety of abnormalities: from the cell membrane to the cytosol and nucleus. At the cell membrane level, biophysical plasma membrane fluidity, and membrane-bound receptors such as the beta-adrenergic, muscarinic and cannabinoid receptors are abnormal either functionally or structurally. Other changes include ion channels such as L-type calcium channels, potassium channels, and sodium transporters. In the cytosol, calcium release and uptake processes are dysfunctional and the myofilaments such as myosin heavy chain and titin, are either functionally abnormal or have structural alterations. Like the fibrotic liver, the heart in cirrhosis also shows fibrotic changes such as a collagen isoform switch from more compliant collagen III to stiffer collagen I which also impacts diastolic function. Other abnormalities include the secondary messenger cyclic adenosine monophosphate, cyclic guanosine monophosphate, and their downstream effectors such as protein kinase A and G-proteins. Finally, other changes such as excessive apoptosis of cardiomyocytes also play a critical role in the pathogenesis of cirrhotic cardiomyopathy.

Meanwhile, SCAD typically presents as an acute coronary syndrome (ACS). Despite the majority of SCAD presentation being characterized by typical ACS signs and symptoms, young age at presentation with an atypical atherosclerotic risk factor profile is responsible for late medical contact and misdiagnosis. The diagnostic algorithm is similar to that for ACS. Low-risk factors prevalence and young age would push toward non-invasive imaging (such as coronary computed tomography (CT)); instead, the gold standard diagnostic exam for SCAD is an invasive coronary angiography (ICA) due to its increased sensitivity and disease characterization. Moreover, intravascular imaging (IVI) improves ICA diagnostic performance, confirming the diagnosis and clarifying the disease mechanism. A SCAD-ICA classification recognizes four angiographic appearances according to lesion extension and features (radiolucent lumen, long and diffuse narrowing, focal stenosis, and vessel occlusion). Concerning its management, the preferred approach is conservative due to the high rates of spontaneous healing in the first months and the low rate of revascularization success (high complexity percutaneous coronary intervention (PCI) with dissection/hematoma extension risk). Revascularization is recommended in the presence of high-risk features (such as left main or multivessel involvement, hemodynamic instability, recurrent chest pain, or ST elevation). The first choice is PCI; coronary artery bypass graft (CABG) is considered only if PCI is not feasible or too hazardous according to the operators' and centers' experience. Medical therapy includes beta blockers in cases of ventricular dysfunction; however, no clear data are available about antiplatelet treatment because of the supposed risk of intramural hematoma enlargement. Furthermore, screening for extracardiac arthropathies or connective tissue diseases is recommended due to the hypothesized association with SCAD. Eventually, SCAD follow-up is important, considering the risk of SCAD recurrence. Considering the young age of patients with SCAD, subsequent care is essential (including psychological support, also for relatives) with the aim of safe and complete reintegration into a non-limited everyday life.</p>","PeriodicalId":20989,"journal":{"name":"Reviews in cardiovascular medicine","volume":"25 12","pages":"448"},"PeriodicalIF":1.9,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11683698/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142915527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
