Insights
The factor XIII Val34Leu polymorphism is more common in patients with cardiac syndrome X (CSX), suggesting a potential genetic link. This finding may aid in understanding CSX risk factors.
Area of Science:
- Cardiology
- Genetics
- Molecular Biology
Background:
- Cardiac Syndrome X (CSX) is characterized by chest pain despite normal coronary arteries.
- Understanding the genetic underpinnings of CSX is crucial for risk stratification and management.
- Factor XIII (FXIII) is involved in hemostasis and may play a role in thrombotic disorders.
Purpose of the Study:
- To investigate the frequency of factor XIII gene polymorphism in patients diagnosed with cardiac syndrome X.
- To determine if specific factor XIII variants are associated with an increased risk of developing CSX.
Main Methods:
- A cross-sectional, observational study involving 48 female CSX patients and 36 age- and gender-matched controls.
- CSX diagnosis criteria included typical chest pain, abnormal exercise ECG, and angiographically normal coronary arteries.
- Factor XIII gene polymorphism was analyzed using the CVD Strip Assay commercial kit.
Main Results:
- The FXIII Val/Leu + Leu/Leu mutation occurred significantly more often in CSX patients (43%) compared to controls (19%) (p=0.02).
- The Leu allele frequency was also higher in the patient group (23.5% vs. 11.1%, p=0.04).
- Multivariate analysis identified FXIII Val34Leu mutation (OR=3.42) and smoking (OR=3.33) as independent predictors of CSX.
Conclusions:
- This study provides evidence supporting an association between the factor XIII Val34Leu polymorphism and cardiac syndrome X.
- The FXIII Val34Leu variant may represent a genetic risk factor for CSX.
- Further research is warranted to elucidate the precise mechanisms linking FXIII polymorphism to CSX pathogenesis.
Background:
The aim of the study was to examine the frequency of factor XIII polymorphism among patients with cardiac syndrome X (CSX).
Methods:
This study was designed as a cross-sectional and observational study. Forty-eight female patients with CSX and 36 controls matched by age, gender, diabetes, and hypertension were studied. CSX was defined as typical chest pain during rest or effort, abnormal test result for exercise ECG, and presence of angiographically normal epicardial coronary arteries after ruling out inducible spasm. Factor XIII gene polymorphism was investigated by using CVD Strip Assay (ViennaLab Diagnostic GmbH) commercial kit.
Results:
The frequency of factor XIII (Val/Leu + Leu/Leu) mutation was significantly higher in patients with CSX (43%) than in controls (19%) (p = 0.02). Frequency of the Leu allele was significantly higher in the patient group (23.5% vs. 11.1%, p = 0.04). Factor XIII (Val/Leu + Leu/Leu) mutation (p = 0.01, OR = 3.42; 95% CI 1.22-9.58) and smoking (p = 0.04, OR = 3.33, 95% CI 1.05-10.58) were identified as independent predictors of the disease in multivariate regression analysis.
Conclusions:
This study indicates that there is an evidence for association between factor XIII Val34Leu polymorphism and CSX.
