[Potassium role in the human body and clinical implications of hyperkalemia].

Potassium is the most represented intracellular electrolyte in the human body. Its extracellular levels are maintained within strict limits through different mechanisms, which constitute the homeostasis of potassium. Hyperkalemia is the most common electrolyte disorder in patients with cardiovascular disease.

The Detection Rate of Late Gadolinium Enhancement in Takotsubo Syndrome: A Systematic Review and Meta-Analysis.

The absence of late gadolinium enhancement (LGE) on cardiac magnetic resonance (CMR) is commonly used to distinguish takotsubo syndrome (TTS) from other myocardial diseases. However, case series have reported the presence of LGE in TTS. This study aimed to summarize the evidence on the frequency of LGE in TTS and identify potential variables that may influence the detection of LGE.

Efficacy of percutaneous stellate ganglion block according to ventricular arrhythmia cycle length: A post hoc subanalysis of the STAR study.

Background: Data on the predictors of percutaneous stellate ganglion block (PSGB) efficacy in electrical storm are scanty.

Objective: We aimed to assess whether PSGB efficacy is influenced by the arrhythmia type and cycle length before the procedure.

Methods: This is a subanalysis of the multicenter STAR study.

Catheter Ablation of Atrial Fibrillation in Patients with Heart Failure: Focus on the Latest Clinical Evidence.

Atrial fibrillation and heart failure are two common cardiovascular conditions that frequently coexist, and it has been widely demonstrated that in patients with chronic heart failure, atrial fibrillation is associated with a significant increase in the risk of all-cause death and all-cause hospitalization. Nevertheless, there is no unanimous consensus in the literature on how to approach this category of patients and which therapeutic strategy (rhythm control or frequency control) is the most favorable in terms of prognosis; moreover, there is still a lack of data comparing the different ablative techniques of atrial fibrillation in terms of efficacy, and many of the current trials do not consider current ablative techniques such as high-power short-duration ablation index protocol for radiofrequency pulmonary vein isolation. Eventually, while several RCTs have widely proved that in patients with heart failure with reduced ejection fraction, ablation of atrial fibrillation is superior to medical therapy alone, there is no consensus regarding those with preserved ejection fraction.

Electrical storm treatment by percutaneous stellate ganglion block: the STAR study.

Background And Aims: An electrical storm (ES) is a clinical emergency with a paucity of established treatment options. Despite initial encouraging reports about the safety and effectiveness of percutaneous stellate ganglion block (PSGB), many questions remained unsettled and evidence from a prospective multicentre study was still lacking. For these purposes, the STAR study was designed.

Real-world data of patients affected by advanced heart failure treated with implantable cardioverter defibrillator and left ventricular assist device: Results of a multicenter observational study.

Background: Left ventricular assist device (L-VAD) implantation is increasingly used in patients with heart failure (HF) and most patients also have an implantable cardioverter defibrillator (ICD). Limited data are available on the incidence of ICD therapies and complications in this special setting. The aim of this study was to analyze the real-world incidence and predictors of ICD therapies, complications and interactions between ICD and L-VAD.

Minor amputation after revascularization in chronic limb-threatening ischemia: What is the optimal timing?

Objectives: Patients with chronic limb-threatening ischemia (CLTI) have a high risk of lower limb amputation and loss of walking independence. Minor amputations play a key role in ensuring walking independence and they represent a challenge in terms of timing and level for vascular surgeons. A major cause of re-amputation is a defect in wound healing and a possible predictor of re-amputation for non-healing wounds could be the incorrect timing of minor amputation after revascularization.

An annotation-independent algorithm based on electrogram characteristics to guide the identification of ventricular tachycardia isthmuses in patients with structural heart disease.

Background: Criteria such as electrograms voltage or late potentials have been largely utilized in the past to help identify areas of substrate maps that are within the ventricular tachycardia (VT) isthmus; yet their specificity and positive predictive value are quite low. The Lumipoint fractionation tool of the Rhythmia system illuminates regions with fractionated electrograms irrespective of their timing and annotation. We aimed to ascertain whether the use of this tool can rapidly identify areas within VT isthmuses from substrate maps.

Left Atrial Anomalous Muscular Band: Case Report, Literature Review, and Role of Three-Dimensional Echocardiography.

Anomalous fibromuscular bands in the left atrium were already described in the 19 century. Recently, the greater attention to the anatomy of the left atrium and the technological improvement have made their finding more frequent. Here, we present six cases, out of approximately 30,000 unselected echocardiograms, in which the use of the three-dimensional echo allowed a better definition of their anatomy, course, and motility.

A comprehensive meta-analysis comparing radiofrequency ablation versus pharmacological therapy for the treatment of atrial fibrillation in patients with heart failure.

Background: Atrial fibrillation (AF) and heart failure (HF) are both associated with worse prognosis and often coexist in the same patients. Whether catheter ablation (CA) is superior to pharmacological therapy in reducing major clinical endpoints in patients with AF and HF is still unsettled.

Objective: To conduct a comprehensive meta-analysis comparing CA with medical therapy (MT) in this population.

Colchicine for cardiovascular medicine: a systematic review and meta-analysis.

Colchicine, a microtubule-disassembling (antitubulin) agent used for centuries for the treatment of gout and autoimmune diseases, is a drug of growing interest in the cardiovascular field. While in the last decades it has become cornerstone of pericarditis treatment, it has also emerged in the last few years as a promising drug in the management of coronary artery disease, atrial fibrillation and heart failure. This systematic review and meta-analysis aimed to assess the efficacy of colchicine in patients with cardiovascular diseases.

Lipoprotein(a) Modulates Carotid Atherosclerosis in Metabolic Syndrome.

High lipoprotein(a) [Lp(a)] is a well-established cardiovascular (CV) risk factor, but the effect of mildly elevated Lp(a) on CV health is largely unknown. Our aim was to evaluate if Lp(a) is associated with the severity of carotid atherosclerosis (CA) in the specific subset of metabolic syndrome (MetS). Subjects with diagnosed MetS and ultrasound-assessed CA were enrolled.

Validation of the ARC-HBR criteria in 68,874 patients undergoing PCI: A systematic review and meta-analysis.

The Academic Research Consortium High Bleeding Risk (ARC-HBR) criteria aims to stratify patients undergoing percutaneous coronary intervention (PCI) and are now recommended by international guidelines to stratify bleeding risk in clinical practice. We searched electronic databases from 2019 (ARC-HBR proposal) up to February 2021 for studies that reported the occurrence of major bleedings according to ARC-HBR status in patients undergoing PCI and pooled them as relative risk (RR) in a random-effect analysis. Only studies that reported events according to the number of times the ARC-HBR definition was met were included in a sensitivity analysis and RR for each stratum was calculated.

Feasibility of an Automatic Ultrasonographic Image Acquisition System Associated With an Artificial Intelligence Algorithm for Real-Time Monitoring of Cardiac Motion During Cardiac Radio-Ablation.

Background: The management of the cardio-respiratory motion of the target and the reduction of the uncertainties related to patient's positioning are two of the main challenges that stereotactic arrhythmia radio-ablation (STAR) has to overcome. A prototype of a system was developed that can automatically acquire and interpret echocardiographic images using an artificial intelligence (AI) algorithm to calculate cardiac displacement in real-time.

Methods: We conducted a single center study enrolling consecutive patients with a history of ventricular arrhythmias (VA) in order to evaluate the feasibility of this automatic acquisition system.

Pharmacologic treatment of acute and recurrent pericarditis: a systematic review and meta-analysis of controlled clinical trials.

Introduction: Recurrence is the most frequent complication following acute pericarditis and may occur in 30% patients, rising to 50% in case of multiple recurrences, lack of colchicine treatment or use of glucocorticoids. Available treatments include aspirin or non-steroidal anti-inflammatory drugs (NSAIDs), colchicine, glucocorticoids, immunosuppressive agents, immunoglobulins, anti-interleukin-1 (IL-1) agents.

Evidence Acquisition: This systematic review and meta-analysis of randomized controlled trials (RCTs) aimed to assess the efficacy of pharmacological treatments for acute and recurrent pericarditis.

Atrial fibrillation in advanced renal failure: are there alternative solutions to warfarin-dicumarol?

Patients with atrial fibrillation (AF) and chronic renal failure (CRF) represent a growing population in epidemiological terms since both conditions increase with advancing age. The association of AF and CRF is burdened with a poor prognosis and with a high risk of adverse events, both ischaemic and haemorrhagic. Oral anticoagulant therapy, in these patients, is more problematic, especially due to the concomitant increased risk of bleeding.

Efficacy and safety of colchicine for the prevention of major cardiovascular and cerebrovascular events in patients with coronary artery disease: a systematic review and meta-analysis on 12 869 patients.

Aims: The key role of inflammation in the pathogenesis of coronary artery disease (CAD) is an urgent call for innovative treatments. Several trials have proposed colchicine as a therapeutic option for secondary prevention in CAD patients but its utilization is hampered by fears about drug-related adverse events (DAEs) and conflicting evidences. The aim of this meta-analysis was to consolidate evidence on the efficacy and safety of colchicine for secondary prevention in patients with CAD.

Colchicine efficacy and safety for the treatment of cardiovascular diseases.

The emerging role of colchicine in the treatment of cardiovascular diseases is a strong demand for a comprehensive understanding of its efficacy and safety. This meta-analysis and systematic review aimed to study the efficacy in the reduction of adverse cardiovascular outcomes (CO), and the risk of colchicine-related adverse events (CRAEs). Fourteen thousand and nine eighty three patients from 22 randomized controlled trials (RCTs) were included, 9 in patients with coronary artery disease-CAD, 9 in patients with pericarditis, 4 in patients with atrial fibrillation-AF or heart failure.

Recurrent pericarditis: an update on diagnosis and management.

Recurrent pericarditis is a true challenge for clinicians, especially when the patient becomes unresponsive or not tolerant to conventional treatments. An accurate diagnosis of recurrent pericarditis, possibly supported by advanced imaging tools, is critical to provide timely and appropriate treatment of symptoms and prevention of further episodes. The incessant research on the inflammatory pathways underlying cardiovascular diseases, led recently to the assessment of anti interleukin-1 agents in the setting of recurrent pericarditis.

Usefulness of Beta-Blockers to Control Symptoms in Patients With Pericarditis.

Exercise restriction is a nonpharmacological treatment of pericarditis that could reduce symptoms by slowing heart rate (HR). Beta-blockers allow pharmacological control of HR. Aim of this paper is to explore the possible efficacy of beta-blockers to improve control of symptoms in patients with pericarditis.
