Insights
Lower plasma levels of Complement C1q tumor necrosis factor-related protein 3 (CTRP3) are linked to atrial fibrillation (AF). This study found reduced CTRP3 in AF patients and correlated it with AF presence and recurrence.
Area of Science:
- Cardiology
- Endocrinology
- Biochemistry
Background:
- Atrial fibrillation (AF) is a common arrhythmia linked to cardiac remodeling.
- Complement C1q tumor necrosis factor-related protein 3 (CTRP3), an adipokine, is associated with metabolic and cardiovascular diseases.
- The relationship between CTRP3 levels and AF remains unclear.
Purpose of the Study:
- To investigate the association between plasma CTRP3 concentrations and the presence of AF.
- To explore the correlation of CTRP3 levels with AF subtypes and recurrence post-ablation.
Main Methods:
- Cross-sectional study comparing 75 AF patients undergoing catheter ablation with 47 control subjects in sinus rhythm.
- Plasma CTRP3 concentrations were measured using ELISA.
- Multivariate regression analysis was employed to identify independent correlations.
Main Results:
- Plasma CTRP3 levels were significantly lower in AF patients compared to controls (366.9 ± 105.2 vs. 429.1 ± 100.1 ng/ml, p=0.002).
- Persistent AF patients showed lower CTRP3 than paroxysmal AF patients (328.3 ± 83.3 vs. 380.0 ± 109.2 ng/ml, p=0.037).
- AF recurrence group had lower CTRP3 levels than the non-recurrence group (337.9 ± 77.3 vs. 386.6 ± 108.1 ng/ml, p=0.045).
Conclusions:
- Plasma CTRP3 concentrations are independently correlated with the presence of AF.
- Lower CTRP3 levels may indicate a higher risk of AF and recurrence after catheter ablation.
Abstract:
Atrial fibrillation (AF) is a highly prevalent cardiac arrhythmia characterized by atrial remodeling. Complement C1q tumor necrosis factor-related protein 3 (CTRP3) is one of the adipokines associated with obesity, diabetes, and coronary heart disease. The association between plasma CTRP3 levels and AF is uncertain. The aim of this study was to investigate whether plasma CTRP3 concentrations were correlated with AF. Our study included 75 AF patients who underwent catheter ablation at our hospital and 47 sinus rhythm patients to determine the difference in plasma CTRP3 concentrations. Blood samples before the ablation were collected, and ELISA was used to measure the concentrations of CTRP3. Plasma CTRP3 concentrations were significantly lower in AF patients compared with control group (366.9 ± 105.2 ng/ml vs. 429.1 ± 100.1 ng/ml, p = 0.002). In subgroup studies, patients with persistent AF had lower plasma CTRP3 concentrations than those with paroxysmal AF (328.3 ± 83.3 ng/ml vs. 380.0 ± 109.2 ng/ml, p = 0.037). The concentrations of plasma CTRP3 in the recurrence group after radiofrequency catheter ablation of AF were lower than those in the nonrecurrence group (337.9 ± 77.3 ng/ml vs. 386.6 ± 108.1 ng/ml, p = 0.045). Multivariate regression analysis revealed the independent correlation between plasma CTRP3 level and AF. Plasma CTRP3 concentrations were correlated with the presence of AF and AF recurrence.
