Insights
Serum gamma-glutamyltransferase (GGT) activity is significantly higher in elderly patients with chronic atrial fibrillation (AF). This finding suggests a potential link between elevated GGT levels and AF, a common heart rhythm disorder.
Area of Science:
- Cardiology
- Biochemistry
- Geriatrics
Background:
- Patients with chronic atrial fibrillation (AF) exhibit increased procoagulant and prothrombotic states.
- Understanding biomarkers associated with AF is crucial for risk stratification and management.
Purpose of the Study:
- To compare serum gamma-glutamyltransferase (GGT) activity between elderly patients with nonvalvular chronic AF and control participants with normal sinus rhythm.
- To investigate the association between serum GGT activity and chronic nonvalvular AF.
Main Methods:
- Retrospective study including 81 elderly patients with nonvalvular chronic AF and 210 age- and gender-matched controls.
- Serum GGT activity was measured and compared between the AF and control groups.
- Demographic and clinical characteristics were analyzed for comparability.
Main Results:
- Serum GGT activity was significantly higher in patients with chronic AF compared to controls (P = .003).
- Key clinical factors including coronary artery disease, hypertension, and diabetes were comparable between groups.
- Serum GGT activity was independently associated with chronic nonvalvular AF.
Conclusions:
- Elevated serum GGT activity is significantly associated with chronic nonvalvular AF in elderly patients.
- GGT may serve as a potential biomarker for AF.
- Further research is warranted to explore the clinical implications of this association.
Abstract:
Procoagulant and prothrombotic states in patients with chronic atrial fibrillation (AF) are higher than those in patients with normal sinus rhythm. We assessed and compared serum γ-glutamyltranferase (GGT) activity in elderly patients with nonvalvular AF and control participants with normal sinus rhythm. Consecutive patients (n = 81) with nonvalvular chronic AF and 210 age- and gender-matched control participants with normal sinus rhythm were retrospectively included in the study from the outpatient cardiology clinic. Presence of coronary artery disease, hypertension, gender, hyperlipidemia, diabetes mellitus, smoking status, glucose, total cholesterol, triglycerides, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and ejection fraction were comparable between the 2 groups (P > .05 for all). However, serum γ-GGT activity was significantly higher (P = .003) in patients with AF compared with those without AF. We have shown that serum γ-GGT activity is independently associated with chronic nonvalvular AF.
