Brugada syndrome mainly affects young subjects with structurally normal heart and can cause x syncope or sudden death due to ventricular arrhythmias, even as the first manifestation, in approximately 5–10% of cases. To date, two questions remain open: how to recognize subjects who will experience arrhythmic events and how to treat them. The guidelines suggest treating subjects with a previous history of cardiac arrest or arrhythmogenic syncope, while they are unconclusive about the management of asymptomatic patients, who represent ∼90% of Brugada patients. We recently demonstrated that in asymptomatic patients, the presence of spontaneous Brugada type 1 electrocardiogram (ECG) pattern and inducibility of ventricular arrhythmias at electrophysiological study allows us to identify a group of patients at greater risk who deserve treatment. Regarding treatment, there are three options: implantable cardioverter defibrillator, drugs, and epicardial transcatheter ablation. Recent studies have shown that the latter is effective and free from serious side effects, thus opening a new scenario in the treatment of Brugada patients at risk. Subjects who present drug-induced-only type 1 Brugada ECG pattern, in whom a spontaneous type 1 pattern has been ruled out with repeated ECGs and 12-lead 24-h Holter monitoring, represent a very low-risk group, provided they adhere to behavioural recommendations and undergo regular follow-up.

Intracranial haemorrhage (ICH) is the most feared haemorrhagic complication of oral anticoagulant therapy (OAT), although the risk is significantly lower with direct oral anticoagulants (DOACs) compared with warfarin. Intracranial haemorrhage is generally considered, by clinicians, to be an absolute contraindication to starting or resuming OAT in patients with atrial fibrillation (AF). On the other hand, the pivotal trials with DOACs excluded patients with previous ICH. Observational studies actually indicate a net clinical benefit in favour of DOAC in patients with AF and previous ICH. This benefit is confirmed by randomized clinical trials which, however, have the limitation of the small number of cases, but larger clinical trials comparing DOACs vs. aspirin or no therapy are underway. While OAT is certainly contraindicated in patients with lobar ICH and cerebral amyloid angiopathy, in other cases, the decision must be made in the individual patient through an accurate balance between thromboembolic risk and haemorrhagic risk and a multidisciplinary cardio-neurological evaluation.
颅内出血（ICH）是口服抗凝疗法（OAT）最令人担忧的出血性并发症，尽管与华法林相比，直接口服抗凝剂（DOAC）的风险要低得多。临床医生通常认为，颅内出血是心房颤动（房颤）患者开始或恢复 OAT 的绝对禁忌症。另一方面，DOACs 的关键试验排除了既往有 ICH 的患者。观察性研究实际上表明，在心房颤动和既往有 ICH 的患者中，DOAC 可带来净临床获益。随机临床试验证实了这一益处，但这些试验存在病例数少的局限性，目前正在进行更大规模的临床试验，比较 DOAC 与阿司匹林或不治疗的差异。虽然大叶 ICH 和脑淀粉样血管病患者肯定禁用 OAT，但在其他情况下，必须根据患者的具体情况，在血栓栓塞风险和出血风险之间进行准确权衡，并进行多学科的心内科-神经科评估后才能做出决定。

Multivessel coronary artery disease (MVD) is a frequently encountered condition in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) of the culprit vessel. Several studies have demonstrated the benefit of complete coronary revascularization compared with the treatment of the culprit lesion only in patients with STEMI. Based on this evidence, the current European guidelines recommend that in haemodynamically stable patients with STEMI and MVD, routine complete revascularization should be achieved either during the same procedure in concomitance with the treatment of the culprit lesion (immediate multivessel PCI) or with a subsequent intervention within 45 days from the index PCI of the culprit lesion (deferred multivessel PCI). However, the guidelines do not express a preference for immediate vs. delayed multivessel PCI. Therefore, the optimal timing of the treatment of non-culprit lesions in patients with STEMI and haemodynamic stability is still debated and has been evaluated in recent studies that showed the non-inferiority of immediate vs. delayed multivessel PCI. The article discusses the results and clinical implications of these studies on the timing of complete revascularization of non-culprit lesions in haemodynamically stable patients with STEMI.

A dyssynchronous biventricular activation, which can be determined by left bundle branch block, chronic right ventricular pacing, frequent premature ventricular complexes, or pre-excitation, can cause a global abnormal contractility, thus leading to systolic dysfunction and left ventricular remodelling in a unique nosological entities: abnormal conduction-induced cardiomyopathies. In this clinical scenario, the mainstay therapy is eliminating or improving LV dyssynchrony, removing the trigger. This usually ensures the improvement and even recovery of cardiac geometry and left ventricular function, especially in the absence of genetic background. A multidisciplinary approach, integrating advanced multimodal imaging, is essential for the systematic aetiological definition and the subsequent evaluation and aetiology-guided therapies of patients and their families. This review aims to describe mechanisms, prevalence, risk factors, and diagnostic and therapeutic approach to the various abnormal conduction-induced cardiomyopathies, starting from reasonable certainties and then analysing the grey areas requiring further studies.

Sudden cardiac death remains a critical public health concern globally, affecting millions annually. Recent advances in cardiac arrhythmia mapping have demonstrated that the ventricular epicardial region has a critical arrhythmogenic role in some inherited cardiogenetic diseases. Among these, long-QT syndrome (LQTS) exposes patients to the risk of life-threatening arrhythmic events. Despite advancements, there is a need for more effective therapeutic strategies. A recent study has uncovered a noteworthy connection between LQTS and epicardial structural abnormalities, challenging the traditional view of LQTS as purely an electrical disorder. High-density mapping revealed electroanatomic abnormalities in the right ventricular epicardium, presenting a potential target for catheter ablation, to finally suppress ventricular fibrillation recurrences in high-risk LQTS patients.

There is a clear demonstration of the inverse linear correlation between LDL cholesterol levels and clinical benefit. However, the timing of the action of lipid-lowering drugs is not clear. According to animal studies with recombinant lipoprotein A-1, the composition of atherosclerosis changes within 40 h (with variations in lipid and inflammatory contents). Progression–regression studies of atherosclerosis in humans confirm the data, highlighting a rapid change in the plaque over 5 weeks. The data are also in line with what emerges from the survival curves of the old study comparing atorvastatin 80 mg vs. placebo (Myocardial Ischaemia Reduction with Aggressive Cholesterol Lowering). The spacing of the curves occurs after only 4 weeks, indicating the precociousness of the favourable effects of powerful statins. Finally, a recent Odyssey post hoc analysis compared the risk of cardiac death and coronary revascularization between a group in which alirocumab lowered LDL cholesterol to below 15 mg (Group 1 and in which the drug was therefore stopped) against the subjects in the placebo group (Group 2), applying a propensity score matching. The primary endpoint occurred in a lower percentage of patients in Group 1 (6.4 vs. 8.4%). Furthermore, patients in Group 1 had a significantly lower hazard ratio (HR) for major adverse cardiovascular events [0.72; 95% confidence interval (CI) 0.51–0.997; P = 0.047] compared with the entire alirocumab group vs. placebo (HR 0.85; 95% CI 0.78–0.93; P < 0.001). According to these preliminary observations, aggressive and early treatment of hypercholesterolaemia in subjects with acute coronary syndrome translates into improved clinical results compared with a strategy that provides for more gradual control. These data will need to be confirmed through further prospective clinical studies and ideally with early conducted atherosclerosis regression studies.

Tricuspid regurgitation (TR) is common both in patients with left side valvular heart disease and in patients with permanent atrial fibrillation and is associated with increased mortality, morbidity, and an increased risk of hospitalization. Surgery for isolated tricuspid repair is a viable option but burdened by a high-operative risk and a post-operative course characterized by high morbidity. Recently, percutaneous interventional techniques have emerged as a viable option in selected high-risk patients who may clinically benefit from tricuspid valve repair. The purpose of this article is to provide an overview of the current state of transcatheter restorative treatment of TR by providing an overview of new devices in clinical development.

The overwhelming evidence that the reduction of LDL cholesterol (LDLc) levels is associated with a parallel reduction in cardiovascular (CV) risk has led the scientific community to progressively and constantly reduce the optimal therapeutic targets of LDLc, both in patients with known CV disease and in patients undergoing primary prevention. The recent introduction of proprotein convertase subtilisin/kexin type 9 inhibitors has allowed clinicians to observe reductions in LDLc levels that go well beyond the limits set by the main international guidelines; following the ‘the lower the better’ paradigm, it is natural to ask how low LDLc can be reduced, whether this intervention is associated with a further reduction in CV risk and, above all, whether there are no issues related to safety in the use of polypharmacotherapies that determine an extreme reduction in LDLc levels. The purpose of this article is to summarize the main scientific evidence on the topic, trying to provide an answer to all clinicians who ‘would like their LDLc to be—almost—zero’.

Atrial fibrillation (AF) represents the most common arrhythmia in clinical practice, characterized by irregular atrial electrical activity originating mainly in and around the pulmonary veins. This condition can manifest itself symptomatically or silently but still dangerously. Complications associated with AF include stroke, heart failure, worst clinical outcome in patients with underlying conditions, increased emergency room visits, hospitalizations, and cardiovascular mortality. Currently, according to the main international guidelines, antiarrhythmic therapy is considered the first choice for rhythm control in patients with AF despite modest efficacy and non-negligible side effects. In recent decades, radiofrequency catheter ablation has emerged as an alternative to antiarrhythmic drugs for rhythm control. Cryoablation was developed with the aim of reducing procedural times and reducing complications related to the ablative procedure with radiofrequency without losing efficacy. Recent studies conducted with rigour and scientific solidity have demonstrated on the one hand that the results of this technique are not inferior compare with radiofrequency. This study aims to compare data on the safety and efficacy of cryoablation with those obtained from antiarrhythmic drugs through a review of the most recent scientific evidence.

The concept of myocardial viability is usually referred to areas of the myocardium, which show contractile dysfunction at rest and in which contractility is expected to improve after revascularization. The traditional paradigm states that an improvement in function after revascularization leads to improved health outcomes and that assessment of myocardial viability in patients with ischaemic left ventricular dysfunction (ILVD) is a prerequisite for clinical decisions regarding treatment. A range of retrospective observational studies supported this ‘viability hypothesis’. However, data from prospective trials have diverged from earlier retrospective studies and challenge this hypothesis. Traditional binary viability assessment may oversimplify ILVD’s complexity and the nuances of revascularization benefits. A conceptual shift from the traditional paradigm centred on the assessment of viability as a dichotomous variable to a more comprehensive approach encompassing a thorough understanding of ILVD’s complex pathophysiology and the salutary effect of revascularization in the prevention of myocardial infarction and ventricular arrhythmias is required.

A conceptual shift from the traditional paradigm centred on the assessment of viability as a dichotomous variable to a more comprehensive approach encompassing a thorough understanding of ILVD’s complex pathophysiology and the salutary effect of revascularization in the prevention of myocardial infarction and ventricular arrhythmias is required.","PeriodicalId":11956,"journal":{"name":"European Heart Journal Supplements","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140794909","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
