Echocardiographic findings in COVID-19 patients include left or right ventricular dysfunction, including abnormal longitudinal strain and focal wall motion abnormalities, valvular dysfunction and pericardial effusion. Additionally, some of these echocardiographic abnormalities have been shown to correlate with biomarkers and adverse clinical outcomes, suggesting an additional prognostic value of echocardiography.

Seven patients were diagnosed as responders and 9 patients as non-responders after 6 months of standard CRT pacing.

Haemodynamic parameters derived from right heart catheterization assist in the selection of an appropriate MCS device and escalation of mechanical support where needed. Evidence favouring the use of one MCS device over another is scant. An intra-aortic balloon pump is the most commonly used short-term MCS device, despite providing only modest haemodynamic support.

Despite reducing LDL cholesterol, there remains a significant risk of cardiovascular disease. Inflammatory and metabolic pathways contribute to recurrence of cardiovascular events, and are often missed in clinical practice. Eicosapentaenoic acid (EPA) may play a crucial role in reducing residual risk of cardiovascular disease. In this review we discuss the clinical applications of omega-3 fatty acids (OM3FAs), their mechanism of action, the difference between pure EPA and docosahexaenoic acid components, and the latest cardiovascular outcome trials and imaging trials evaluating coronary plaque. PubMed and EMBASE were searched to include all the remarkable clinical trials investigating OM3FAs and cardiovascular disease. Beyond statins, additional medications are required to reduce the risk of cardiovascular disease. EPA has shown cardiovascular benefit in addition to statins in large outcome trials. Additionally, multiple serial-imaging studies have demonstrated benefits on plaque progression and stabilization. Due to its pleotropic properties, icosapent ethyl outperforms other OM3FAs in decreasing cardiovascular disease risk in both patients with and without high triglycerides, and is currently recommended as an adjunct to statins. To further strengthen the current evidence, additional research is required to elucidate the inconsistencies between the effects of pure EPA and EPA plus docosahexaenoic acid.","PeriodicalId":12836,"journal":{"name":"Heart International","volume":"16 1 1","pages":"2-11"},"PeriodicalIF":0.2,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67593563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional care in patients with HF is usually based on clinical history and physical examination. Natriuretic peptides (NPs), B-type NP (BNP) and N-terminal proBNP, are the gold-standard biomarkers in HF. They are recommended for diagnosing HF, when the physician is uncertain of the diagnosis, and for estimating the prognosis. NPs also guide therapy in HF, as serial NP measurements inform medication adjustments to achieve targets independently of symptoms. In this regard, the data are conflicting. In patients with HF and reduced left ventricular ejection fraction (HFrEF) there is a suggestion that NP-guided therapy is helpful. The studies STARS-BNP and PROTECT demonstrated a reduction in cardiac events with NP-guided therapy. Additionally, mortality in patients aged <75 years reduced in the BATTLESCARRED and TIME-CHF studies, and in a meta-analysis. On the contrary, no differences were observed in the studies PRIMA and GUIDE-IT. In HF with preserved ejection fraction (HFpEF) and in the acute setting, no differences were detected with NP-guided therapy compared with conventional care.

In both cases (radiofrequency and cryoablation), the main limitation is their inability to achieve durable lesions without causing collateral damage to adjacent structures. In contrast, pulsed electric field (PEF) ablation is a non-thermal energy source that causes cell apoptosis by applying an electric current to the tissue. Lesions created by a field of energy seem to be more contiguous than traditional ablation, and the risk of damage to adjacent tissues is largely avoided due to the properties of the tissues and electrical fields. In recent years, new catheters capable of delivering PEF have been developed and are now undergoing clinical testing.
