“…The relationship between MHT and CAS has not been previously reported. Atrial and ventricular arrhythmias are important manifestations of cardiac target organ injury and are closely related to cardiovascular events such as coronary heart disease and sudden cardiac death [17]. Hypertension is significantly associated with increased atrial and ventricular arrhythmias, and the mechanism may be related to changes in cardiac structure [18].…”

This study aimed to investigate whether hypertension phenotypes such as white-coat hypertension (WCHT), diagnosed with the addition of nighttime blood pressure (BP) criteria, are related to coronary artery stenosis (CAS) and cardiac arrhythmia. In this cross-sectional observational study, 844 participants who did not use antihypertensive, lipid-lowering, and antiplatelet drugs were selected. The subjects were divided into normotensive (NT), WCHT, masked hypertension (MHT), and sustained hypertension (SHT) groups based on the results of clinic BP measurement and ambulatory BP monitoring. Coronary angiography and ambulatory electrocardiography were performed to determine the participants' CAS and cardiac arrhythmia status. Coronary angiography revealed 556 patients with CAS and 288 participants with normal coronary arteries. The chisquared test showed that the incidence of CAS was higher in the MHT and SHT groups than in the NT group, while no significant change was found in the WCHT group (P = 0.003, P < 0.001, P = 0.119). The logarithm of the Gensini score was used to compare the degree of CAS between the groups. Multiple linear regression analysis showed that the degree of CAS was higher in the WCHT, MHT, and SHT groups than in the NT group (P < 0.05). The incidences of frequent atrial premature beats, atrial tachycardia, and ventricular cardiac arrhythmia were significantly higher in the WCHT and SHT groups than in the NT group, while only ventricular cardiac arrhythmia changes were observed in the MHT group. This study found that hypertension phenotypes such as WCHT were closely associated with CAS and cardiac arrhythmia.NT normotension, WCHT white-coat hypertension, MHT masked hypertension, SHT sustained hypertension, Lg (Gensini score) the logarithm of Gensini score, SD standard deviation, β standardized regression coefficient, SE standard error *P value, WCHT versus NT; **P value, MHT versus NT; ***P value, SHT versus NT Effects of white-coat, masked and sustained hypertension on coronary artery stenosis and cardiac. . .

“…En deportistas menores de 35 años de edad, la causa principal de muerte súbita son las afecciones cardiacas hereditarias; entre el 40% y el 50% de los fallecimientos de deportistas jóvenes de forma súbita se deben a esta causa, y la tasa de ocurrencia aumenta cuando estos sujetos realizan ejercicio. En los deportistas mayores a 35 años de edad,la principal causa de muerte súbita es por enfermedad coronaria aterosclerótica (6,7,(15)(16)(17)(18) .…”

Despite the low rates of occurrence, Sudden Death occurs in healthy athletes and even in high performance sports events worldwide. Its etiology is attributed mainly to cardiovascular diseases and congenital pathologies. The main objective of this article, is to compile and review specialized articles to establish the state-of-the-art in this matter. A specialized search was conducted in PubMed, Science Direct, Scielo, Redalyc and La Referencia databases, identifying 43.608 related articles, selecting 29 of them which meet certain adopted selection criteria. Finally, the main causes, symptoms and trigger factors of Sudden Death are identified and analyzed, and the procedures oriented to prevention and proper management of these events, as well as the necessary training of capabilities and skills aimed at the first respondents, are described.

BackgroundPulsed‐field ablation (PFA) is a cutting‐edge technique that employs non‐thermal energy to cause cell death by inducing irreversible electroporation of cell membranes. This systematic review evaluates the PFA effectiveness as a potential alternative to radiofrequency and cryo‐ablation for treating ventricular tachycardia.MethodsPubMed, Embase, Scopus, and Web of Science were systematically searched using keywords related to ventricular tachycardia and pulsed‐field ablation. Eligible Studies evaluating this therapeutic approach for ventricular tachycardia were included in the final analysis.ResultsWe included six studies (five case reports and one case series) in our systematic review. Eight (88.8%) of procedures were successful with 100% long‐term efficacy. No procedural complications or ventricular tachycardia (VT) recurrence were observed in the cases.ConclusionThe absence of complications, high effectiveness, and long‐term success rate make PFAs a good VT treatment option. However, PFA safety and efficacy studies for VT treatment are scarce. Thus, larger investigations on this topic are urgently needed.
