Thrombotic complications of atrial fibrillation continue to pose a significant challenge in clinical practice today. Left atrial appendage occlusion (LAAO) has emerged as a promising alternative to oral anticoagulation for high-risk patients with atrial fibrillation. However, despite the potential benefits, there is still the possibility of life-threatening complications such as device dislocation.

Predischarge oxygen uptake efficiency slope has short and long-term value in the prognosis of patients after acute myocardial infarction.

J Chin Med Assoc

Department of Physical Medicine and Rehabilitation, School of Medicine, College of Medicine, Kaohsiung Medical University, Kaohsiung, Taiwan, ROC.

Article Synopsis
  • Patients who survive an acute myocardial infarction (AMI) are at increased risk for major cardiovascular events (MACE), and cardiopulmonary exercise testing (CPET) can help with exercise prescriptions and risk stratification.
  • This study analyzed data from 113 AMI patients who underwent CPET after treatment, revealing that the oxygen uptake efficiency slope (OUES 100) is a strong predictor for future MACE occurrences at 3 months, 2 years, and 5 years post-event.
  • The results indicated that lower values of OUES per body surface area significantly correlate with higher risks of MACE, emphasizing the importance of identifying submaximal predictors in patients recovering from AMI.

Background: Kidney dysfunction (KD) is a main limiting factor of applying guideline-directed medical therapy (GDMT) and reaching the recommended target doses (TD) in heart failure (HF) with reduced ejection fraction (HFrEF).

Hypothesis: We aimed to assess the success of optimization, long-term applicability, and adherence of neurohormonal antagonist triple therapy (TT:RASi [ACEi/ARB/ARNI] + βB + MRA) according to the KD after a HF hospitalization and to investigate its impact on prognosis.

Methods: The data of 247 real-world, consecutive patients were analyzed who were hospitalized in 2019-2021 for HFrEF and then were followed-up for 1 year.

Department of Medicine, Chulabhorn Hospital, Chulabhorn Royal Academy, 906 Kamphaengphet 6 Road, Talat Bang Khen, Lak Si, Bangkok, 10210, Thailand.

Background: Cardiac catheterization and endovascular procedures are extensively used in modern medicine, and procedural stroke is one of the major complications that the catheterization laboratory team may face in their everyday work. Recognizing the signs and symptoms of procedural stroke is crucial to ensuring appropriate management. We herein report a case of internuclear ophthalmoplegia that caused blurred vision, diplopia, and dizziness on lateral gaze as an unusual presentation of procedural stroke.

EuroEchoLab Craiova Cardiology Center, Emergency Hospital Craiova, Romania, Str Tabaci nr 1, Craiova, Romania.

Mitral regurgitation is among the most common valvular heart diseases. Mitral regurgitation in patients with dilated cardiomyopathy is a complex pathology involving annular dilatation, papillary muscle displacement, systolic leaflet tethering, and left ventricular remodeling. Quantification of mitral apparatus damage in these patients is essential for successful interventional and surgical therapy.

Objective: The prevalence of smoking combustible cigarettes has decreased, but rates of nicotine vaping among adolescents and young adults have increased dramatically. Vaping is associated with acute health problems and exposes users to toxic metals with unknown long-term consequences. Research on factors influencing vaping is needed to inform the development of effective prevention and intervention methods.

TRPM2 enhances ischemic excitotoxicity by associating with PKCγ.

Cell Rep

February 2024

Department of Cell Biology, Calhoun Cardiology Center, University of Connecticut School of Medicine (UConn Health), Farmington, CT 06030, USA. Electronic address:

Article Synopsis
  • The study explores how NMDAR-mediated glutamate excitotoxicity is a major cause of cell death in ischemic stroke, highlighting the failure of past treatments targeting NMDARs in clinical trials.
  • Researchers discovered a specific interaction between TRPM2 and PKCγ that contributes to the excitotoxic process, proposing that breaking this interaction could be a new therapeutic approach.
  • By developing a peptide (TAT-M2PBM) to disrupt the TRPM2-PKCγ coupling, the study shows that this uncoupling reduces calcium influx and excitotoxic effects, ultimately protecting neurons from ischemic damage.

The noninvasive assessment of oxygen consumption, carbon dioxide production, and ventilation during a cardiopulmonary exercise test (CPET) provides insight into the cardiovascular, pulmonary, and metabolic system's ability to respond to exercise. Exercise physiology has been shown to be distinct for competitive athletes and highly active persons (CAHAPs), thus creating more nuanced interpretations of CPET parameters. CPET in CAHAP is an important test that can be used for both diagnosis (provoking symptoms during a truly maximal test) and performance.

CRISPR Activation Reverses Haploinsufficiency and Functional Deficits Caused by Truncation Variants.

Circulation

April 2024

The Jackson Laboratory for Genomic Medicine, Farmington, CT (S.G., A.K., N.L., K.T., Y.Z., H.T., C.-L.W., J.T.H.).

Background: truncation variants (TTNtvs) are the most common genetic lesion identified in individuals with dilated cardiomyopathy, a disease with high morbidity and mortality rates. TTNtvs reduce normal TTN (titin) protein levels, produce truncated proteins, and impair sarcomere content and function. Therapeutics targeting TTNtvs have been elusive because of the immense size of TTN, the rarity of specific TTNtvs, and incomplete knowledge of TTNtv pathogenicity.

TTN truncation variants produce sarcomere-integrating proteins of uncertain functional significance.

J Clin Invest

January 2024

Department of Biomedical Engineering, Yale University, New Haven, Connecticut, USA.

Titin (TTN) is one of the largest and most complex proteins expressed in humans, and truncation variants are the most prevalent genetic lesion identified in individuals with dilated cardiomyopathy (DCM) or other disorders of impaired cardiac contractility. Two reports in this issue of the JCI shed light on a potential mechanism involving truncated TTN sarcomere integration and the potential for disruption of sarcomere structural integrity. Kellermayer, Tordai, and colleagues confirmed the presence of truncated TTN protein in human DCM samples.

Introduction: Cardiovascular diseases (CVDs) are major global health problem and are the third leading cause of death in the world. Most studies found the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) were correlated with myocardial infarction and heart failure. Previous studies reported a higher risk of CVD among physicians but no study concerns NLR and the PLR to predict coronary artery disease (CAD) among the physicians.
