Review highlights racial disparities in sudden cardiac arrest and death among athletes

Medical Xpress - Cardiology

A recent major review of data published by The Lancet and led by Emory sports cardiologist Jonathan Kim, MD, shows that Black athletes are approximately five times more likely to experience sudden cardiac arrest (SCA) and sudden cardiac death (SCD) compared to white athletes, despite some evidence of a decline in rates of SCD overall. SCA and SCD have historically been a leading cause of mortality among athletes, particularly those involved in high-intensity sports.

Heart-brain interactions: clinical evidence and mechanisms based on critical care medicine

Frontiers in Cardiovascular Medicine

In this review paper, we search the recent literature regarding the application of the heart-brain interaction theories in the field of intensive care unit. Simultaneously, we methodically summarize the clinical evidence supporting its application in intensive care unit treatment, based on clinical randomized trials and clinical case studies. We delve into how it's applied in treating severely ill patients and in researching animal models for cardio-cerebral comorbidities, aiming to supply bench

What type of devices should a person with a pacemaker be cautious about?

All About Cardiovascular System and Disorders

Pacemakers are cardiac implantable electronic devices. As they use radiofrequency signals for programming, other radiofrequency signals can interfere with the function of pacemakers. Notable one is magnetic resonance imaging if you consider in hospital scenarios.

Design-related bias in studies investigating diagnostic tests for venous thromboembolic diseases: a systematic review and meta-analysis

Frontiers in Cardiovascular Medicine

BackgroundEarly detection and diagnosis of venous thromboembolism are vital for effective treatment. To what extent methodological shortcomings exist in studies of diagnostic tests and whether this affects published test performance is unknown.ObjectivesWe aimed to assess the methodological quality of studies evaluating diagnostic tests for venous thromboembolic diseases and quantify the direction and impact of design characteristics on diagnostic performance.MethodsWe conducted a literature sea

Echocardiogram in Tetralogy of Fallot

All About Cardiovascular System and Disorders

Parasternal long axis view showing colour flow from right ventricle to aorta through the ventricular septal defect with overriding aorta. Flow is predominantly blue in colour because it is away from the transducer kept at the parasternal region. Right ventricle is an anterior structure and aortic root is relatively posterior to it, and hence the anteroposterior flow depicted in blue colour.

Thrombomodulin is a stronger indicator of combined oral contraceptives-induced activated protein C pathway resistance in the thrombin generation test than activated protein C

Frontiers in Cardiovascular Medicine

BackgroundThe mechanism by which combined oral contraceptives (COCs) lead to hypercoagulation is not fully understood, although activated protein C (APC) pathway resistance has been implicated. APC and thrombomodulin (TM) tend to be considered as interchangeable reagents, even though their biological action in coagulation is different. However, it remains unclear which reagent is better suited for the detection of APC pathway resistance.

The detailed transseptal puncture technique for optimal closure in patients with a patent foramen ovale

Frontiers in Cardiovascular Medicine

BackgroundThe closure of a patent foramen ovale (PFO) using transseptal puncture has particular advantages and disadvantages. Thus, transseptal puncture should be re-evaluated in detail.AimsWe aimed to assess the effectiveness of the detailed transseptal puncture technique in patients who underwent PFO closure due to cryptogenic stroke or transient ischemic attack in terms of residual shunts and atrial fibrillation.MethodsWe prospectively analyzed 144 consecutive patients who underwent PFO closu

Transcatheter ablation of atrioventricular nodal reentry tachycardia in children and congenital heart disease in the era of 3D mapping

Frontiers in Cardiovascular Medicine

Atrioventricular nodal reentrant tachycardia (AVNRT) is a common supraventricular tachycardia in children and congenital heart disease (CHD) patients. Nowadays, in large enough children, chronic treatment for symptomatic and recurrent AVNRT episodes relies on transcatheter ablation. Indeed, many three-dimensional (3D) mapping strategies and ablation techniques have been developed and it helped to increase success rates and to reduce complications.

Effect of high-intensity intermittent rehabilitation training on physical function, gut microbiome and metabolite after percutaneous coronary intervention in patients with coronary heart disease

Frontiers in Cardiovascular Medicine

BackgroundPostoperative rehabilitation exercise training after percutaneous coronary intervention (PCI) is crucial for coronary heart disease (CHD) patients in restoring health and preventing recurrence, including high-intensity interval training (HIIT). However, the impact of HIIT on cardiopulmonary function, gut microbiome and metabolite remains underexplored.MethodsThis study included 60 patients with CHD who underwent percutaneous coronary intervention (PCI).

Case Report: Anomalous origin of the right coronary artery leading to cardiac arrest induced by sexual activity: a previously unreported pathogenetic condition

Frontiers in Cardiovascular Medicine

BackgroundThe Anomalous Origin of the Right Coronary Artery from the Left Coronary Sinus (ARCA-LCS) is a rare congenital cardiac condition where the right coronary artery emerges from the left sinus instead of the right coronary sinus of Valsalva. The clinical significance of ARCA-LCS lies in its potential to cause myocardial ischemia or sudden cardiac death, particularly under physical exertion.
