Causal Relationship between PECAM-1 Level and Cardiovascular Diseases: A Mendelian Randomization Study

Announcing a new article publication for Cardiovascular Innovations and Applications journal. Platelet endothelial cell adhesion molecule (PECAM-1) is present in the vascular endothelium and plays important roles in various biological processes. Several recent studies have reported associations between PECAM-1 and cardiovascular diseases (CVDs). However, further research is necessary to clarify the causal effects of PECAM-1 on CVDs.

To determine whether PECAM-1 and CVDs are causally associated, the authors of this article conducted a two-sample Mendelian randomization (TSMR) study.

Causal Associations Between the Gut Microbiome and Aortic Aneurysm: A Mendelian Randomization Study

Announcing a new article publication for Cardiovascular Innovations and Applications journal.  Observational studies have indicated an association between the gut microbiota and the occurrence and progression of aortic aneurysm (AA). However, the causal relationship between the gut microbiota and AA and its subtypes remains unclear. This study used Mendelian randomization (MR) to gain new insights into the relationship between the gut microbiota and AA, including AA subtypes.

Rheumatoid Arthritis and Risk of Atrial Fibrillation: Results from Pooled Cohort Studies and Mendelian Randomization Analysis

Announcing a new article publication for Cardiovascular Innovations and Applications journal. Observational research has indicated that individuals diagnosed with rheumatoid arthritis (RA) have an elevated likelihood of developing atrial fibrillation (AF). The authors of this article performed meta-analysis and Mendelian randomization (MR) analysis to explore the correlation and potential causal relationship between RA and AF. PubMed, Embase, and Web of Science were searched for cohort studies comparing AF risk among participants with and without RA. Quantitative synthesis of the adjusted risk ratio (RR) or hazard ratio was performed with the random-effects model. RA and AF were studied with two-sample MR analysis with the random-effects inverse variance weighted method. Patients with RA had a higher risk of AF than participants without RA [RR = 1.32, 95% confidence interval (CI): 1.23–1.43, P < 0.0001]. Genetically predicted RA was not associated with a significantly elevated risk of AF (odds ratio = 1.009, 95% CI: 0.986–1.032, P = 0.449). After adjustment for confounding factors in multifactorial MR, RA and AF still showed no correlation. Sensitivity analyses yielded similar results, thus indicating the robustness of the causal association. Overall, RA was associated with elevated risk of AF in this meta-analysis. However, genetically predicted RA may not be causal.
