Background: Thrombomodulin (TM) a membrane receptor for thrombin generated in blood in vivo, is present on the surface of vascular endothelium cells. The aim of our work was the determination of thrombomodulin in the blood of patients with unstable angina pectoris.
Material And Methods: In the study took part 87 patients with unstable angina pectoris (40 women and 47 men) at age 41-79 years. Thrombomodulin was determined in citrated blood plasma with the use of enzyme immunoassay ELISA with the diagnostic kit manufactured by American Diagnostica.
Results: Statistically significant higher thrombomodulin concentration (sTM) was found in the patients when compared with the values recorded in control group. Elevated sTM levels depended on patients age and they were significantly higher in patients over 50 years old. There were no statistically significant differences with respect to patients gender and coexistent risk factors such as arterial hypertension, diabetes or smoking, but significantly higher sTM concentration was observed in patients with high serum cholesterol level.
Conclusion: Elevated sTM concentrations result from the damage to vascular endothelium cells by the atheromatous process manifested in unstable angina pectoris.

Cardiovascular disease continues to be a major contributor to global morbidity and mortality, with environmental and occupational factors such as air pollution, noise, and shift work increasingly recognized as potential contributors. Using a two-sample Mendelian randomization (MR) approach, this study investigates the causal relationships of these risk factors with the risks of unstable angina (UA) and myocardial infarction (MI). Leveraging single nucleotide polymorphisms (SNPs) as genetic instruments, a comprehensive MR study was used to assess the causal influence of four major air pollutants (PM, PM, NO, and NO), noise, and shift work on unstable angina and myocardial infarction.

Background/objectives: Vitamin K2 analogs are associated with decreased vascular calcification, which may provide protective benefits for individuals with coronary artery disease (CAD) by stimulating anti-calcific proteins like matrix Gla protein and adjusting innate immune responses. This study addresses a significant gap in understanding the association between serum levels of vitamin K2 analogs in different CAD types and examines their correlations with clinical risk parameters in CAD patients.
Methods: This case-control study enrolled CAD patients and healthy controls to assess and compare serum concentrations of two vitamin K2 analogs including menaquinone-4 (MK-4) and menaquinone-7 (MK-7) via ultra-performance liquid chromatography with tandem mass spectrometry (UPLC-MS/MS).

Acute coronary syndrome (ACS) remains a major global health burden, encompassing a spectrum of conditions from unstable angina to acute myocardial infarction. Despite advancements in early detection and management, ACS is often complicated by the development of heart failure. This systematic review and meta-analysis aimed to identify factors associated with the development of heart failure following acute coronary syndrome.

Purpose: Acute coronary syndrome (ACS), comprising unstable angina and acute myocardial infarction, is the most dangerous and fatal form of coronary heart disease. This study evaluates serum bile acids (BAs) and amino acids (AAs) as potential predictors of AMI in UA patients.
Patients And Methods: A total of 72 Non-Coronary Artery Disease (NCAD) patients, 157 UA patients, and 79 AMI patients were analyzed.

Objective: An association between white blood cell count (WBC-C) before percutaneous coronary intervention (PCI) and prognosis has been established in patients undergoing PCI. However, the effect of WBC-C after PCI on the long-term prognosis of patients with unstable angina pectoris (UA) is unclear.
Methods: A retrospective cohort study was conducted in 1811 consecutive patients with UA.
