Review
: The simultaneous use of cocaine and alcohol is highly prevalent and is associated with high numbers of emergency department admissions, primarily due to cardiovascular complications. Aims: To answer the question of whether the co-use of cocaine and alcohol increases the cardiovascular risk compared to the use of cocaine alone. : A systematic review of human studies comparing the cardiovascular risk of co-used cocaine and alcohol with the use of cocaine alone. : Despite a higher myocardial workload induced by the co-use of cocaine and alcohol and the potentiation of cocaine's cardiovascular effects by alcohol, the findings on the risk and severity of cardiovascular symptoms due to combined use are inconsistent. However, the co-use of cocaine and alcohol clearly leads to higher mortality. Interestingly, the presence of cocaethylene, a unique metabolite generated only via a pharmacokinetic interaction between alcohol and cocaine, carries an 18- to 25-fold increase over the absence of cocaethylene (cocaine-alone users) in the risk of sudden death and is associated with myocardial injury and cardiac arrest, probably due to the inhibition of cardiac ion channels by cocaethylene. : Despite the inconsistency in some of the results, it is concluded that the co-use of cocaine and alcohol poses an additional risk of cardiovascular fatalities compared to the use of cocaine alone.

What Are the Care Needs of Families Experiencing Sudden Cardiac Arrest? A Survivor- and Family-Performed Systematic Review, Qualitative Meta-Synthesis, and Clinical Practice Recommendations.
INTRODUCTION
Cardiac arrest care systems are being designed and implemented to address patients', family members', and survivors' care needs. We conducted a systematic review and a meta-synthesis to understand family experiences and care needs during cardiac arrest care to create treatment recommendations.
METHODS
We searched eight electronic databases to identify articles. Study findings were extracted, coded and synthesized. Confidence in the quality, coherence, relevance, and adequacy of data underpinning the resulting findings was assessed using GRADE-CERQual methods.
RESULTS
In total 4181 studies were screened, and 39 met our inclusion criteria; these studies enrolled 215 survivors and 418 family participants-which includes both co-survivors and bereaved family members. From these studies findings and participant data we identified 5 major analytical themes: (1) When the crisis begins we must respond; (2) Anguish from uncertainty, we need to understand; (3) Partnering in care, we have much to offer; (4) The crisis surrounding the victim, ignore us, the family, no longer; (5) Our family's emergency is not over, now is when we need help the most. Confidence in the evidence statements are provided along with our review findings.
DISCUSSION
The family experience of cardiac arrest care is often chaotic, distressing, complex and the aftereffects are long-lasting. Patient and family experiences could be improved for many people. High certainty family care needs identified in this review include rapid recognition and response, improved information sharing, more effective communication, supported presence and participation, or supported absence, and psychological aftercare.

Meta-Analysis Review
BACKGROUND
Cardiac implantable electronic devices (CIED) are a heterogeneous group of medical devices with increasingly sophisticated diagnostic capabilities, which could be exploited in forensic investigations. However, current guidelines are lacking clear recommendations on the topic. The first aim of this systematic review is to provide an updated assessment of the role of postmortem CIED interrogation, and to give practical recommendations, which can be used in daily practice. Secondly, the authors aim to determine the rates of postmortem CIED interrogation and autopsy investigations, the type of final rhythm detected close to death (with a focus on the significance of documented arrhythmias), as well as the role of postmortem CIED interrogation in the determination of final cause/time of death, and any potentially fatal device malfunctions.
METHODS
A systematic search in MEDLINE and Scopus aiming to identify reports concerning postmortem human CIED interrogation was performed, including a systematic screening of reference lists. Case reports, letters to the editors, commentaries, review articles or guidelines were excluded, along with studies related to cardiac devices other than CIED. All data were pooled and analyzed using fixed-effects meta-analysis models, and the I statistic was used to assess heterogeneity.
RESULTS
A total of 25 articles were included in the systematic review, enrolling 3194 decedent CIED carriers. Ten studies (40%) had a 100% autopsy rate, whereas in further 6 studies autopsy findings were variably reported; CIED interrogation was available from 22 studies (88%), and it was never performed prior to autopsy. The overall rate of successful postmortem CIED interrogation was 89%, with high heterogeneity among studies, mainly due to device deactivation/battery discharge. Twenty-four percent of CIED carriers experienced sudden cardiac death (SCD), whereas non-sudden cardiac and non-cardiac death (NSCD, NCD) were reported in 37% and 30% of decedents, respectively. Ventricular tachyarrhythmias were recorded in 34% of overall successfully interrogated CIED, and in 62% of decedents who experienced a SCD; of all ventricular tachyarrhythmias recorded, 40% was found in NSCD or NCD. A clear interpretation of the etiological role of recorded arrhythmias in the causation of death required integration with autopsy findings. Overall, potentially fatal device malfunctions were detected in 12% of cases.
CONCLUSIONS
Postmortem CIED interrogation is a valuable tool for the determination of the cause of death, and may complement autopsy. Forensic pathologists need to know the potential utility, pitfalls, and limitations of this diagnostic examination to make this tool as much reliable as possible.

Review
BACKGROUND
This systematic review aims to highlight the untapped potential of heart rate variability (HRV) and atrial fibrillation (AF) monitoring by wearable health monitoring devices as a critical diagnostic tool in cardiac surgery (CS) patients. We reviewed established predictive capabilities of HRV and AF monitoring in specific cardiosurgical scenarios and provide a perspective on additional predictive properties of wearable health monitoring devices that need to be investigated.
METHODS
After screening most relevant databases, we included 33 publications in this review. Perusing these publications on HRV's prognostic value, we could identify HRV as a predictor for sudden cardiac death, mortality after acute myocardial infarction (AMI), and post operative atrial fibrillation (POAF). With regards to standard AF assessment, which typically includes extensive periods of unrecorded cardiac activity, we demonstrated that continuous monitoring via wearables recorded significant cardiac events that would otherwise have been missed.
RESULTS
Photoplethysmography and single-lead electrocardiogram (ECG) were identified as the most useful and convenient technical assessment modalities, and their advantages and disadvantages were described in detail. As a call to further action, we observed that the scientific community has relatively extensively explored wearable AF screening, whereas HRV assessment to improve relevant clinical outcomes in CS is rarely studied; it still has great potential to be leveraged.
CONCLUSIONS
Therefore, risk assessment in CS would benefit greatly from earlier preoperative and postoperative AF detection, comprehensive and accurate assessment of cardiac health through HRV metrics, and continuous long-term monitoring. These should be achievable via commercially available wearables.

Review
Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a genetic disorder characterized by the progressive fibro-fatty replacement of the right ventricular myocardium, leading to myocardial atrophy. Although the structural changes usually affect the right ventricle, the pathology may also manifest with either isolated left ventricular myocardium or biventricular involvement. As ARVC shows an autosomal dominant pattern of inheritance with variable penetrance, the clinical presentation of the disease is highly heterogeneous, with different degrees of severity and patterns of myocardial involvement even in patients of the same familiar group with the same gene mutation: the pathology spectrum ranges from the absence of symptoms to sudden cardiac death (SCD) sustained by ventricular arrhythmias, which may, in some cases, be the first manifestation of an otherwise silent pathology. An evidence-based systematic review of the literature was conducted to evaluate the state of the art of the diagnostic techniques for the correct post-mortem identification of ARVC. The research was performed using the electronic databases PubMed and Scopus. A methodological approach to reach a correct post-mortem diagnosis of ARVC was described, analyzing the main post-mortem peculiar macroscopic, microscopic and radiological alterations. In addition, the importance of performing post-mortem genetic tests has been underlined, which may lead to the correct identification and characterization of the disease, especially in those ARVC forms where anatomopathological investigation does not show evident morphostructural damage. Furthermore, the usefulness of genetic testing is not exclusively limited to the correct diagnosis of the pathology, but is essential for promoting targeted screening programs to the deceased's family members. Nowadays, the post-mortem diagnosis of ARVC performed by forensic pathologist remains very challenging: therefore, the identification of a clear methodological approach may lead to both a reduction in under-diagnoses and to the improvement of knowledge on the disease.

Risk of Major Adverse Cardiovascular Events and Venous Thromboembolism with JAK Inhibitors versus TNF Inhibitors in Rheumatoid Arthritis Patients: A Systematic Review and Meta-Analysis.
OBJECTIVE
The aim of this study was to compare the risk of major cardiovascular events (MACE) and venous thromboembolic events (VTE) between tumour necrosis factor (TNF) and Janus kinase (JAK) inhibitors in patients with rheumatoid arthritis (RA).
METHODS
We researched PubMed, Scopus, Cochrane Library, and clinicaltrials.gov until December of 2023 for randomised controlled trials (RCTs) and observational studies. The outcomes studied were MACE (stroke, heart attack, myocardial infarction, sudden cardiac death) and VTE (deep vein thrombosis, pulmonary embolism). We pooled data using random effects model. Risk for the reported outcomes was expressed as odds ratio (OR) with a 95% confidential interval (CI). We performed a subgroup analysis based on study design.
RESULTS
We identified 23 studies, 20 of which compared the odds for MACE and 14 the odds for VTE between JAK and TNF inhibitors in RA patients. Ten studies were RCTs and the rest were observational. Regarding MACE risk we pooled data from a total of 215,278 patients (52,243 were treated with JAK inhibitors, while the rest 163,035 were under TNF inhibitors). Compared with TNF inhibitors, the OR for JAK inhibitors in regards with MACE risk was 0.87 (0.64-1.17, p<0.01). Regarding VTE, a total of 176,951 patients were analysed (41,375 JAK inhibitors users and 135,576 TNF inhibitors users). The OR for VTE for JAK inhibitors compared with TNF inhibitors was 1.28 (0.89-1.84, p<0.01).
CONCLUSION
According to our results, there is no statistically significant difference for MACE or VTE in RA patients who receive either JAK or TNF inhibitors.

BACKGROUND AND AIMS
Fragmented QRS (fQRS), which is associated with rhythm disturbances, can predispose the heart to fatal ventricular arrhythmias. Recently, accumulating studies indicates that fQRS is associated with poor prognosis in various types of cardiomyopathies. Therefore, we assessed the association between fQRS with all-cause mortality and major arrhythmic events (MAEs) in patients with nonischemic cardiomyopathy, in this systematic review and meta-analysis study.
METHODS
We performed a comprehensive search in databases of PubMed/Medline, EMBASE, and Web of Science from the beginning to December 31, 2022. Published observational studies (cohorts, case-control, or analytical cross-sectional studies) were included that report the prognostic value of fQRS in patients with different types of nonischemic cardiomyopathies for MAEs (sudden cardiac death, sudden cardiac arrest, sustained ventricular tachycardia [VT], ventricular fibrillation [VF], and appropriate shock) and all-cause mortality. We pooled risk ratios (RRs) through raw data and adjusted hazard ratios (aHRs) using "Comprehensive Meta-Analysis" software, Version 2.0.
RESULTS
Nineteen cohort and three analytical cross-sectional studies were included in this meta-analysis involving a total of 4318 subjects with nonischemic cardiomyopathy (1279 with fQRS and 3039 without fQRS). FQRS was significantly associated with an increased risk of all-cause mortality in patients with nonischemic cardiomyopathy (pooled RR: 1.920; 95% confidence interval [CI]: 1.388-2.656, < 0.0001/pooled HR: 1.729; 95% CI: 1.327-2.251, < 0.0001). Also, the risk of developing MAEs in the presence of fQRS was significantly increased (pooled RR: 2.041; 95% CI: 1.644-2.533, < 0.0001/pooled HR: 3.626; 95% CI: 2.119-6.204, < 0.0001). In the subgroup analysis, the strongest association between fQRS presence and increased MAEs was observed in patients with hypertrophic cardiomyopathy (HCM) (pooled RR: 3.44; 95% CI: 2.07-5.71, < 0.0001/pooled HR: 3.21; 95% CI: 2.04-5.06, < 0.0001).
CONCLUSION
Fragmented QRS could be a prognostic marker for all-cause mortality and MAEs in patients with various types of nonischemic cardiomyopathies, particularly HCM.

BACKGROUND
Isolated left ventricular apical hypoplasia (ILVAH), also known as truncated left ventricle (LV), is a very unusual cardiomyopathy. It is characterised by a truncated, spherical, and non-apex forming LV. The true apex is occupied by the right ventricle. Due to the rarity of the disease, just a few case reports and limited case series have been published in the field.
AIM
To analysing the so far 37 reported ILVAH cases worldwide.
METHODS
The electronic databases PubMed and Scopus were investigated from their establishment up to December 13, 2022.
RESULTS
The majority of cases reported occurred in males (52.7%). Mean age at diagnosis was 26.1 ± 19.6 years. More than a third of the patients were asymptomatic (35.1%). The most usual clinical presentation was breathlessness (40.5%). The most commonly detected electrocardiogram changes were T wave abnormalities (29.7%) and right axis deviation with poor R wave progression (24.3%). Atrial fibrillation/flutter was detected in 24.3%. Echocardiography was performed in 97.3% of cases and cardiac MRI in 91.9% of cases. Ejection fraction was reduced in more than a half of patients (56.7%). An associated congenital heart disease was found in 16.2%. Heart failure therapy was administered in 35.1% of patients. The outcome was favorable in the vast majority of patients, with just one death.
CONCLUSION
ILVAH is a multifaceted entity with a so far unpredictable course, ranging from benign until the elderly to sudden death during adolescence.

Review
BACKGROUND
High-grade atrioventricular block (HGAVB) is common after transcatheter aortic valve implantation (TAVI), often necessitating permanent pacemaker (PPM) implantation. Delayed HGAVB has varying definitions but typically refers to onset 48 hours after TAVI or following discharge and may cause syncope and sudden cardiac death. This review estimates the incidence of delayed HGAVB and identifies limitations of current literature.
METHODS
A systematic review was performed of the following online databases: Medline, Cochrane, Web of Science, and Scopus. Studies that labelled the outcome of "delayed" or "late" atrioventricular block after TAVI were included; patients with previous PPM or aortic valve surgery were excluded. Initial search yielded 775 studies, which, after screening, was narrowed to 19 studies.
RESULTS
Nineteen studies with 14,898 patients were included. Mean age was 81.7 years, and 46.3% were male. Mean Society of Thoracic Surgeons (STS) score was 5.6%, and 31.3% of patients had known atrial fibrillation. The most common access site was transfemoral (84.8%), whereas balloon-expandable valves were used in 62.1%, self-expanding valves in 34.0%, and mechanically expanding valves in 3.9% of cases. The incidence of delayed HGAVB ranged from 1.7% to 14.6%, with significant methodologic heterogeneity noted among the included studies.
CONCLUSIONS
Delayed HGAVB is a common and potentially serious complication of TAVI, with similar risk factors to acute HGAVB. With a move toward an early discharge strategy post-TAVI, further prospective study of delayed HGAVB is warranted to improve understanding of predisposing factors, incidence, timing, and implications.

Left ventricular noncompaction cardiomyopathy (LVNC) is a structural heart defect that has been associated with generation of arrhythmias in the population and is a cause of sudden cardiac death with severe systolic dysfunction and fatal arrhythmias. LVNC has gained increasing acknowledgment with increased prevalence. We conducted a systematic review of reported electrocardiogram (ECG) results for pediatric LVNC patients. EMBASE database query was performed, yielding 4531 articles related to LVNC between 1990 and December 2023. Patient age ranged from prenatal to 18 years of age. Qualitative analyses were performed to characterize individual arrhythmias, and summative interpretation of ECG evaluations was gathered for the entire cohort. Systematic review of 57 LVNC cases and ECG presentation revealed many waveform consistencies, including abnormal left ventricular, atrioventricular node, and interventricular septal patterns, and specifically a high incidence of Mobitz type II and Wolff-Parkinson-White waveforms. This review of ECG analysis reinforces the clinical and etiologic significance of pediatric LVNC. While LVNC in pediatric populations may not always present as acute clinical cases, further investigation into the electrophysiology of the disease supports the need for further evaluation and risk stratification for patients with suspected LVNC and/or ventricular arrhythmia.
