The predominant PAR4 variant in individuals of African ancestry worsens murine and human stroke outcomes
Protease-activated receptor 4 (PAR4) (gene F2RL3) harbors a functional dimorphism, rs773902 A/G (encoding Thr120/Ala120, respectively) and is associated with greater platelet aggregation. The A allele frequency is more common in Black individuals, and Black individuals have a higher incidence of ischemic stroke than White individuals. However, it is not known whether the A allele is responsible for worse stroke outcomes. To directly test the in vivo effect of this variant on stroke, we generated mice in which F2rl3 was replaced by F2RL3, thereby expressing human PAR4 (hPAR4) with either Thr120 or Ala120. Compared with hPAR...

Platelet glycoprotein IIb/IIIa inhibitor tirofiban in clopidogrel-na ïve patients undergoing elective percutaneous coronary intervention
CONCLUSION: Ad-hoc PCI in clopidogrel-naïve patients who were treated with high-dose bolus of tirofiban followed by a clopidogrel loading dose immediately after the procedure appeared to be safe.PMID:37713051 | DOI:10.1007/s12471-023-01810-2

Off-Label Reduced Dose Apixaban in Older Adults With Atrial Fibrillation and Associated Outcomes
CONCLUSION AND RELEVANCE: Older adults with nonvalvular AF are commonly prescribed lower-than-recommended doses of apixaban. However, no significant association was found between empiric off-label reduced dosing and stroke or bleeding outcomes.PMID:37712551 | DOI:10.1177/10600280231199137

Report on Cardiovascular Health and Diseases in China 2022: an Updated Summary
Biomed Environ Sci. 2023 Aug 20;36(8):669-701. doi: 10.3967/bes2023.106.ABSTRACTIn the past 30 years, the accessibility and quality index of medical care have made remarkable progress in China, ranking the first among middle-income countries. Many cardiovascular technologies are at or near the world's leading level, and significant progress has been achieved in China solving the problem of "treatment difficulty" of cardiovascular diseases (CVD). However, due to the prevalence of unhealthy lifestyles among Chinese residents, a huge population with CVD risk factors, accelerated population aging, and other reasons, the incide...

Oral microbiome mediated inflammation, a potential inductor of vascular diseases: a comprehensive review
Front Cardiovasc Med. 2023 Aug 30;10:1250263. doi: 10.3389/fcvm.2023.1250263. eCollection 2023.ABSTRACTThe dysbiosis of the oral microbiome and vascular translocation of the periodontopathic microorganism to peripheral blood can cause local and systemic extra-oral inflammation. Microorganisms associated with the subgingival biofilm are readily translocated to the peripheral circulation, generating bacteremia and endotoxemia, increasing the inflammation in the vascular endothelium and resulting in endothelial dysfunction. This review aimed to demonstrate how the dysbiosis of the oral microbiome and the translocation of oral...

Steady solution and its stability of a mathematical model of diabetic atherosclerosis
J Biol Dyn. 2023 Dec;17(1):2257734. doi: 10.1080/17513758.2023.2257734.ABSTRACTAtherosclerosis is a leading cause of death worldwide. Making matters worse, nearly 463 million people have diabetes, which increases atherosclerosis-related inflammation. Diabetic patients are twice as likely to have a heart attack or stroke. In this paper, we consider a simplified mathematical model for diabetic atherosclerosis involving LDL, HDL, glucose, insulin, free radicals (ROS), β cells, macrophages and foam cells, which satisfy a system of partial differential equations with a free boundary, the interface between the blood flow and th...
