Summary: TNNI3K, an understudied kinase mainly expressed in the heart, has been implicated in various cardiac phenotypes and physiological processes. Human genetic variants in TNNI3K are associated with supraventricular arrhythmias, conduction disease, and cardiomyopathy. Studies in mice also suggest its involvement in cardiac hypertrophy, regeneration, and recovery after ischemia/reperfusion injury, with potential as a target for clinical treatments in different cardiac diseases.

Summary: Sudden cardiac death is often due to cardiac arrhythmia, with CAD being a common underlying cause. Arrhythmic complications can occur in ACS patients, with ECG and echocardiography being useful for diagnosis. CMR can assess post-ACS function and complications.

Summary: This study used a pig model to investigate the effects of systemic antioxidative treatment on reperfusion arrhythmias. The results showed that myocardial oxidation was increased early after reperfusion, but systemic antioxidative treatment did not reduce the incidence of reperfusion arrhythmias.

Summary: Chronic treatment with the dual SGLT-1 and 2 inhibitor sotagliflozin (Sto) improves left ventricular remodeling and reduces the incidence of ventricular arrhythmias (VAs) after myocardial infarction (MI) by modulating the TLR4/CaMKII signaling pathway.

Summary: The TRPM4 channel plays a crucial role in the heart, participating in multiple physiological processes including cardiac conduction, hypertrophic adaptations, and potentially cardiac arrhythmias. Research has shown that TRPM4 is essential for survival and is required to activate the Akt and Calcineurin pathways, while also regulating transient calcium amplitudes that may lead to cellular arrhythmias. This channel has two functions: a role in adaptive hypertrophy, and an association with NCX that could trigger cellular arrhythmias.

Summary: A peptide mimetic called p1159, derived from collagen, was found to reduce left ventricular dilation and fibrosis in a mouse model of myocardial infarction. This study aimed to test the potential of p1159 to reduce adverse cardiac remodeling in a chronic MI model and to elucidate its mode-of-action. The results showed that p1159 significantly improved systolic function post-MI and promoted the formation of a compliant and organized infarct scar, leading to reduced adverse cardiac remodeling.

Summary: Acute alcohol consumption can lead to cardiac arrhythmias related to the 'Holiday Heart Syndrome' by causing autonomic imbalance, with increased sympathetic activity and decreased parasympathetic activity. This imbalance may trigger arrhythmias, as shown by changes in measures of the cardiac autonomic nervous system during alcohol administration.

Summary: This study revealed a direct correlation between serum PIIINP levels, severity of cardiac fibrosis, and indicators of diastolic function after 1 year of STEMI with preserved LVEF. Patients with PIIINP levels exceeding 381.4ng/ml on the 12th day post-STEMI had an increased risk of cardiac fibrosis. Monitoring PIIINP levels during the inpatient period may help identify high-risk patients for cardiac fibrosis 1 year after STEMI with preserved LVEF.

Summary: This study reveals the importance of cardiac resident macrophages in the efficient clearance and degradation of apoptotic cardiomyocytes during myocardial infarction, which is crucial for inflammation resolution and tissue repair. The researchers identified Lgmn as a key gene involved in this process and demonstrated its functional significance through various experiments.

Summary: The study reveals that the LPL/AQP7/GPD2-mediated glycerol metabolism plays a crucial role in preventing myocardial ischemia-related damage. Deficiencies in these enzymes and proteins can lead to exacerbated cardiac dysfunction and apoptosis following myocardial infarction. Additionally, the activation of GPD2 under ischemic conditions facilitates ATP synthesis, while LPL deficiency can impact the effectiveness of PPAR alpha agonist treatment for MI-induced cardiac dysfunction.

Summary: Research has shown the significant role of store-operated calcium channels (SOCC) in the kidney, regulating the function of various cells through Ca2+ signaling and impacting renal function. SOCC is activated by depletion of Ca2+ stores, playing a crucial role in blood pressure regulation, fluid balance, electrolyte balance and other functions in the kidney.

Summary: Hypoxia plays a crucial role in the pathogenesis of neurological disorders and can have both beneficial and detrimental effects on brain aging and mortality. Controlled exposure to hypoxic environments may represent a potential treatment strategy for neurodegenerative diseases. Special attention is needed when considering the risks and benefits of hypoxia exposure in the elderly population.
