BACKGROUND A polypill that includes key medications associated with improved outcomes (aspirin, angiotensin-converting-enzyme [ACE] inhibitor, and statin) has been proposed as a simple approach to the secondary prevention of cardiovascular death and complications after myocardial infarction. METHODS In this phase 3, randomized, controlled clinical trial, we assigned patients with myocardial infarction within the previous 6 months to a polypill-based strategy or usual care. The polypill treatment consisted of aspirin (100 mg), ramipril (2.5, 5, or 10 mg), and atorvastatin (20 or 40 mg). The primary composite outcome was cardiovascular death, nonfatal type 1 myocardial infarction, nonfatal ischemic stroke, or urgent revascularization. The key secondary end point was a composite of cardiovascular death, nonfatal type 1 myocardial infarction, or nonfatal ischemic stroke. RESULTS A total of 2499 patients underwent randomization and were followed for a median of 36 months. A primary-outcome event occurred in 118 of 1237 patients (9.5%) in the polypill group and in 156 of 1229 (12.7%) in the usual-care group (hazard ratio, 0.76; 95% confidence interval [CI], 0.60 to 0.96; P=0.02). A key secondary-outcome event occurred in 101 patients (8.2%) in the polypill group and in 144 (11.7%) in the usual-care group (hazard ratio, 0.70; 95% CI, 0.54 to 0.90; P=0.005). The results were consistent across prespecified subgroups. Medication adherence as reported by the patients was higher in the polypill group than in the usual-care group. Adverse events were similar between groups. CONCLUSIONS Treatment with a polypill containing aspirin, ramipril, and atorvastatin within 6 months after myocardial infarction resulted in a significantly lower risk of major adverse cardiovascular events than usual care.

Introduction: Wearable cardioverter-defibrillators (WCD) have emerged as a valuable tool in the management of patients at risk for life-threatening arrhythmias. These devices offer a non-invasive and temporary solution, providing continuous monitoring and the potential for prompt defibrillation when needed. In this study, we explore the use of WCD and evaluate arrhythmic events through comprehensive monitoring., Methods: From November 2022 to May 2024, we conducted an outpatient follow-up of 41 patients receiving WCD. Regular check-ups, remote monitoring and comprehensive echocardiography were performed to optimise a tailored therapy., Results: The average age of the patients was 59.2.4±16.5 years, with 78% being male. Among the cohort, 54% had hypertension, 41% were smokers and 66% had dyslipidaemia, while 27% were diabetic. WCD was assigned according to the Italian Association of Hospital Cardiologists position paper focussing on the appropriate use of WCD and European Society of Cardiology guidelines on ventricular arrhythmias and the prevention of sudden cardiac death: 24 (58%) patients had a de novo diagnosis of heart failure with reduced ejection fraction, 11 (27%) patients had a recent acute coronary syndrome and ejection fraction <35%, 3 (7%) patients had a cardiac electronic device extraction and 3 (7%) patients had myocarditis with features of electrical instability. The average follow-up was 62±38 days according to specific aetiology, with a daily wearing time of 22.7±1.3 hours. No device interventions were recorded. At the end of the follow-up period, 15 patients still required an implantable cardioverter-defibrillator (ICD). Among these, 12 patients (29%) underwent ICD implantation. Two patients (5%) declined the procedure., Conclusions: The use of WCD for patients at high risk of arrhythmias allowed to optimise therapy and limit the indications for ICD. Inappropriate implantation of ICD was avoided in 69% of patients who received WCD. The device showed a good safety profile, low incidence of device interventions and adequate patients' adherence to WCD use., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Cardiac amyloidosis, in the three forms of immunoglobulin light chain (AL), transthyretin (ATTR) wild type (ATTRwt) and mutated (ATTRv) amyloidosis, is an increasingly known and recognized disease in the cardiovascular setting. The first stage of the patient's journey is the clinical suspicion of the disease, which is placed, in presence of a hypertrophic phenotype, by the identification of red flags, both extracardiac and cardiac clues whose presence increase the probability of being faced with a patient with this disease. The second stage is represented by diagnosis, which occurs with certainty through the identification of amyloid substance in cardiac tissue. This stage is spotted in wo parts, i.e. disease confirmation and disease etiology definition (AL vs ATTRwt vs ATTRv). However, it is possible in some selected cases to make a diagnosis of ATTR without the need for tissue assessment, in presence of a positive grade 2-3 bisphosphonate scintigraphy and absence of monoclonal component. Once the diagnosis has been made, the third stage is the assessment of prognosis, the fourth is the patient therapy pathway and fifth is the follow-up plan. Prognosis evaluation is based on different staging systems at the onset of the disease, whose applicability in the era of new effective therapies is still to be defined. To date, the transthyretin tetramer stabilizer tafamidis is the only approved treatment for both wild-type and mutant ATTR cardiomyopathy without polyneuropathy, while ATTRv with associated neuropathy can benefit from treatment with patisiran, an inhibitor of hepatic protein synthesis. Therapies for complications and comorbidities, must be addressed individually, due to the lack of specific clinical trials on this category of patients. In fact, it is important to take into consideration the risks linked to the use of some drugs due to the infiltration of the conduction tissue by the amyloid substance, which increases the risk of bradycardia and heart blocks, the tendency towards hypotension and the increased thromboembolic risk. It is also essential to follow the course of the disease and the efficacy of the treatment in affected patients with a standardized follow-up, and to identify early the signs/symptoms of the disease in asymptomatic TTR mutation carriers.This ANMCO position paper on amyloidosis aims to provide the clinical cardiologist with a practical summary of the disease, to accompany the patient with amyloidosis in the various stages of his journey.

Atherosclerosis often affects the coronary arterial tree. Frequently the disease does not translate in significant narrowing of the vessels, thus determining only a non-obstructive disease. This condition that is described as non-obstructive coronary artery disease (NobsCAD) should be distinguished from the absence of disease (i.e. smooth coronary arteries) as it carries a specific prognostic value. The detection and reporting of NobsCAD should prompt preventive measures that can be individualized upon the degree of the underlying burden of disease. The accompanying clinical condition, the other cardiovascular risk factors present, and the description of the severity and extent of NobsCAD should provide the framework for an individualized treatment that should also consider the best available scientific evidence and guidelines. The description of NobsCAD represents important information to be collected whenever a coronary angiogram (both invasive and non-invasive) is performed. Treating the patient according to the presence and extent of NobsCAD offers prognostic benefits well beyond those offered by considering only the traditional cardiovascular risk factors. In order to reach this goal, NobsCAD should not be confused with the absence of coronary atherosclerosis or even ignored when detected as if it was a trivial information to provide., (Published on behalf of the European Society of Cardiology. © The Author(s) 2021.)

Continuous improvement of technologies, devices and drugs needs a renewal and update of current recommendations and guidelines on antithrombotic strategies, especially in those fields where literature lacks of established scientific evidences. Accordingly, the aim of this consensus statement is to provide support for antithrombotic therapy based on current guidelines and the most recent scientific evidences.After an overview on the currently available devices, the appropriate therapy according to type of procedure and implanted device is discussed. The occurrence of postoperative thromboembolic and/or hemorrhagic complications is analyzed, along with the appropriate diagnostic tools and therapeutic approach. A section is dedicated to counseling to pregnancy in women with heart valve prosthesis. Finally, the role of novel oral anticoagulants is discussed, and indications are provided for the management of patients undergoing surgery or interventional procedures on oral anticoagulation therapy.

Objectives: We sought to assess hydroquinidine (HQ) efficacy in selected patients with Brugada syndrome (BrS)., Background: Management of asymptomatic patients with BrS and inducible arrhythmias remains a key issue. Effectiveness of class Ia antiarrhythmic drugs, which inhibit the potassium transient outward current of the action potential, has been suggested in BrS., Methods: From a cohort of 106 BrS patients, we studied 35 who received HQ (32 men; mean age 48 +/- 11 years). Patients had asymptomatic BrS and inducible arrhythmia (n = 31) or multiple appropriate shocks from an implantable cardioverter-defibrillator (ICD) (n = 4). Asymptomatic patients with inducible arrhythmia underwent electrophysiologic (EP)-guided therapy. When ventricular tachycardia (VT)/ventricular fibrillation (VF) inducibility was not prevented, or in case of HQ intolerance, an ICD was placed., Results: Hydroquinidine prevented VT/VF inducibility in 76% of asymptomatic patients who underwent EP-guided therapy. Syncope occurred in two of the 21 patients who received long-term (17 +/- 13 months) HQ therapy (1 syncope associated with QT interval prolongation and 1 unexplained syncope associated with probable noncompliance). In asymptomatic patients who received an ICD (n = 10), one appropriate shock occurred during a follow-up period of 13 +/- 8 months. In patients with multiple ICD shocks, HQ prevented VT/VF recurrence in all cases during a mean follow-up of 14 +/- 8 months., Conclusions: Hydroquinidine therapy prevented VT/VF inducibility in 76% of asymptomatic patients with BrS and inducible arrhythmia, as well as VT/VF recurrence in all BrS patients with multiple ICD shocks. These preliminary data suggest that preventive treatment by HQ may be an alternative strategy to ICD placement in asymptomatic patients with BrS and inducible arrhythmia.

The Brugada syndrome is characterised clinically by the occurrence of syncope or sudden death due to ventricular arrhythmias in patients with structurally normal hearts and electrocardiographic signs of right bundle branch block and ST elevation in the right precordial leads (V1 to V3). The transmission of the condition is autosomal dominant with variable penetration. Mutations have been identified in a gene coding for the alpha sub-unity of the sodium channel (SCN5A) on chromosome 3 in only 30% of cases. This mutation is responsible for a reduction of the density of the sodium current and explains the aggravation of the electrocardiographic anomalies by antiarrhythmic drugs which block the sodium channels. The prognosis is poor in symptomatic patients and depends on the prevention of sudden death by the implantation of an automatic defibrillator. The therapeutic decision is much more difficult in asymptomatic patients without a family history. The authors propose a decisional algorithm. The management may have to be modified in the months or years to come depending on advances in the understanding of this syndrome.
