Three men, aged 67 years, 80 years and 53 years, respectively, developed signs and symptoms of progressive right-sided heart failure following open heart surgery. They were diagnosed with constrictive pericarditis based on echocardiography, cardiac magnetic resonance and cardiac catheterisation. Following pericardiectomy, two of the patients fully recovered, while one, the 80-year-old man, died during convalescence. When signs and symptoms of progressive right-sided heart failure develop after open heart surgery, a diagnosis of constrictive pericarditis should be considered. Constrictive pericarditis after open heart surgery may be caused by inflammation of the pericardium; an old, fibrotic haemopericardium, which may be diffuse or loculated; pericardial adhesions; or a combination of these entities. Diagnosing constrictive pericarditis is difficult and may take a long time. However, it is important to recognise this disorder early before it has progressed to an advanced stage. Pericardiectomy is the only effective therapy. When performed too late, survival is significantly reduced.

Acute Concurrent Exercise Improves Inhibitory Control Without Mediating the Role of Lactate: An Event-Related Potential Study.
Sports Med Open
January 2025
Department of Physical Education and Sport Sciences, National Taiwan Normal University, 162, Section 1, Heping E. Road, Taipei, 106, Taiwan.
Background: Concurrent exercise (CE), an emerging exercise modality characterized by sequential bouts of aerobic (AE) and resistance exercise (RE), has demonstrated acute benefits on executive functions (EFs) and neuroelectric P3 amplitude. However, the effect of acute CE on inhibitory control, a sub-component of EFs, and P3 amplitude remains inconclusive. Moreover, exploring the mechanisms underlying the effects of acute exercise on EFs contributes to scientific comprehension, with lactate recognized as a crucial candidate positively correlated with EFs.

Background: Lerodalcibep, a small binding anti-PCSK9 protein (adnectin), showed effective LDL cholesterol reduction in heterozygous familial hypercholesterolaemia. We aimed to assess the safety and efficacy of lerodalcibep and evolocumab in a globally diverse homozygous familial hypercholesterolaemia population.
Methods: This phase 3, randomised, open-label, crossover, non-inferiority study consisted of two 24-week treatment periods separated by an 8-week washout.
Assessment of hemodynamic disturbances and impaired ventricular filling in asymptomatic fontan patients: A 4D flow CMR study.
Eur J Radiol Open
June 2025
Department of Radiology, Shanghai Children's Medical Center, Shanghai Jiao Tong University School of Medicine, 1678 Dong Fang Road, Shanghai 200127, PR China.
Background: The Fontan procedure is a surgical intervention designed for patients with single ventricle physiology, wherein the systemic venous return is redirected into the pulmonary circulation, thereby facilitating passive pulmonary blood flow without the assistance of ventricular propulsion. Consequently, long-term follow-up of individuals who have undergone the asymptomatic Fontan procedure is essential.
Objectives: The aims of this investigation were to: 1) examine the impact of flow components and kinetic energy (KE) parameters on hemodynamic disturbances in asymptomatic Fontan patients and control group; 2) Assess left ventricular diastolic dysfunction through the analysis of 4D flow parameters across different Fontan sub-groups; 3) Compare intracardiac flow parameters among Fontan sub-groups based on morphological features of the left ventricle (LV) and right ventricle (RV).
Spirituality-Based Intervention in Hypertension: EFfects on Blood PrEssure and EndotheliaL Function-FEEL Trial Results.
Glob Heart
January 2025
Spirituality and Cardiovascular Medicine Department, Brazilian Cardiology Society -DEMCA/SBC, Brasil.
Background: Emerging evidence suggests that spirituality improves patient outcomes, however, this has undergone only limited evaluation in randomized trials. Hypertension is a major cause of cardiovascular morbidity and mortality worldwide.
Objectives: To evaluate whether a spirituality-based intervention, compared to a control group, can reduce blood pressure (BP) and improve endothelial function after 12 weeks in patients with mild or moderate hypertension (HTN).

Introduction According to the World Health Organization (WHO), cardiovascular diseases are the leading cause of death globally, accounting for approximately 17 million deaths annually, with sudden cardiac arrest (SCA) as a significant contributor to this alarming statistic. SCA, the abrupt loss of heart function, is a critical medical emergency that requires early recognition and immediate cardiopulmonary resuscitation (CPR) for the effective resuscitation of victims. Various studies have shown a low level of knowledge regarding CPR in the community.
