Objective: Recent large-scale genome-wide association studies have identified a novel susceptibility locus on chromosome 9p21.3 that contributes a significant attributable risk for myocardial infarction. The phenotypic significance of this locus in patients with established coronary artery disease is unknown. We sought to compare cardiovascular structure and function in carriers and non-carriers of the risk haplotype in a cross-sectional study.
Methods: We genotyped the rs1333049 single-nucleotide polymorphism in 593 Caucasian individuals with stable coronary artery disease recruited in the Heart and Soul Study. All study subjects underwent resting and stress echocardiography. Linear and logistic regression models were used to examine the association between the rs1333049 polymorphism and echocardiographic parameters of cardiovascular structure and function.
Results: There was no association between rs1333049 genotype and echocardiographic phenotype (left ventricular hypertrophy, systolic dysfunction, diastolic dysfunction, inducible ischemia, exercise capacity, mitral annular calcification, and aortic plaque).
Conclusions: In a cross-sectional study of individuals with stable coronary artery disease, there was no association of chromosome 9p21.3 genotype with cardiovascular structure and function.

Rationale: Traumatic pseudoaneurysm of the sinus of Valsalva (PSV) is a rare but life-threatening condition, often resulting from blunt chest trauma. Rapid progress and a high risk of rupture highlight the importance of prompt diagnosis and intervention. We present a case of a rare pseudoaneurysm linked to the right coronary sinus after blunt chest trauma.

This study assesses the effect of carotid sinus blockade applied with a local anesthetic on hemodynamic parameters during carotid endarterectomy (CEA) operations performed under general anesthesia. The medical records of patients who underwent CEA under general anesthesia between January 2020 and December 2022, were retrospectively reviewed. It was recorded whether the patients received carotid sinus block with 2 mL of 2% prilocaine.

Function-to-find domain (FIIND)-containing proteins, including NLRP1 and CARD8, are vital components of the inflammasome signaling pathway, critical for the innate immune response. These proteins exist in various forms due to autoproteolysis within the FIIND domain, resulting in full-length (FL), cleaved N-terminal (NT), and cleaved C-terminal (CT) peptides, which form autoinhibitory complexes in the steady state. However, the detailed mechanism remains elusive.

Background: Ischemic heart disease (IHD) has a significant impact on public health and healthcare expenditures in the United States (US).
Methods: We used data from the CDC WONDER database from 1999-2020 to identify trends in the IHD-related mortality of patients ≥ 75 years in the US. AAMRs per 100,000 population and APC were calculated and categorized by year, sex, race, and geographic divisions.

Electrical stimulation of existing three-dimensional bioprinted tissues to alter tissue activities is typically associated with wired delivery, invasive electrode placement, and potential cell damage, minimizing its efficacy in cardiac modulation. Here, we report an optoelectronically active scaffold based on printed gelatin methacryloyl embedded with micro-solar cells, seeded with cardiomyocytes to form light-stimulable tissues. This enables untethered, noninvasive, and damage-free optoelectronic stimulation-induced modulation of cardiac beating behaviors without needing wires or genetic modifications to the tissue solely with light.
