Protease activated receptor 2 deficiency retards progression of abdominal aortic aneurysms by modulating phenotypic transformation of vascular smooth muscle cells via ERK signaling.

Abdominal aortic aneurysm (AAA) is characterized by localized structural deterioration of the aortic wall, leading to progressive dilatation and rupture. Protease activated receptor 2 (PAR2) dependent signaling has been implicated in the pathophysiology of atherosclerosis through the regulation of smooth muscle cell function. However, its role in AAA remains unclear.

Phosphate-to-alanine ratio and bilirubin-to-androsterone glucuronide ratio are the hub metabolites in upper gastrointestinal cancers: a Mendelian randomisation (MR) study.

Background: Patients with NVAF are at a higher risk of stroke compared to healthy individuals. Left atrial appendage closure (LAAC) has emerged as a prominent strategy for reducing the risk of thrombosis in individuals with NVAF.

Targeting Rab7-Rilp Mediated Microlipophagy Alleviates Lipid Toxicity in Diabetic Cardiomyopathy.

Diabetic cardiomyopathy (DbCM) is characterized by diastolic dysfunction, which progresses into heart failure and aberrant electrophysiology in diabetic patients. Dyslipidemia in type 2 diabetic patients leads to the accumulation of lipid droplets (LDs) in cardiomyocytes and results in lipid toxicity which has been suggested to drive DbCM. It is aimed to explore potential pathways that may boost LDs degradation in DbCM and restore cardiac function.

Analysis of correlative factors of female coronary slow-flow phenomenon: A retrospective study.

The coronary slow-flow phenomenon (CSFP) is a manifestation of coronary artery disease wherein coronary angiography reveals no apparent stenosis; however, there is a delay in blood flow perfusion. Given its increased occurrence in male patients, with the majority of subjects in previous studies being male, this study aimed to explore whether distinct risk factors are present in female patients with CSFP. This single-center retrospective study focused on female patients diagnosed with CSFP by using coronary angiography.

Methods: This prospective cohort study identified hospitalized adult patients with COVID-19 between April 19, 2022, and June 9, 2022, amid the omicron wave of the pandemic. Matched nirmatrelvir-ritonavir-treated and non-treated cohorts were formed using the propensity score matching method.

Hydrogen sulfide protects cardiomyocytes from doxorubicin-induced ferroptosis through the SLC7A11/GSH/GPx4 pathway by Keap1 S-sulfhydration and Nrf2 activation.

Recent studies have demonstrated that ferroptosis, a novel form of nonapoptotic regulated cell death plays an important role in doxorubicin (DOX)-induced cardiotoxicity (DoIC). Hydrogen sulfide (HS) is emerging as the third important gaseous mediator in cardiovascular system. However, whether HS has an effect on DOX-induced ferroptosis remains unknown.

The impacts of prophylactic anticoagulation therapy during hospitalization on long-term cardiovascular outcomes in high-risk COVID-19 patients amid the omicron wave of the pandemic.

Background: Although prophylactic anticoagulation therapy is suggested to be adopted in severe COVID-19 patients, its effects on the long-term cardiovascular (CV) outcomes, namely the risk of major adverse CV events(MACEs) in high-risk CV patients amid the omicron wave of the pandemic, remain unknown.

2023 Chinese expert consensus on the impact of COVID-19 on the management of cardiovascular diseases.

The primary site of infection in COVID-19 exhibit is the respiratory system, but multiple organ systems could be affected. The virus could directly invade cardiomyocytes. Alternatively, cytokine storm could lead to myocardial injury.

The initial timing and dosage pattern of sacubitril/valsartan in patients with acute myocardial infarction undergoing percutaneous coronary intervention.

Background: In real-world clinical practice, the initiation and up-titration of sacubitril/valsartan remain challenging due to symptomatic hypotension in patients with acute myocardial infarction(AMI). The purpose of this study was to investigate the efficacy of different initial timing and dosage of sacubitril/valsartan in AMI patients.
