Insights
In patients with congestive heart failure (CHF), elevated C-reactive protein (CRP) levels are linked to arterial hypertension and left atrial enlargement. Permanent atrial fibrillation (AF) and CRP also correlate with higher fibrinogen levels.
Area of Science:
- Cardiology
- Internal Medicine
- Biochemistry
Background:
- Atrial fibrillation (AF) negatively impacts left atrial size and cardiac function, and is linked to increased C-reactive protein (CRP) and fibrinogen.
- The relationship between inflammatory markers, AF, and cardiac remodeling in congestive heart failure (CHF) patients is not fully understood.
Purpose of the Study:
- To investigate associations between inflammatory markers (CRP, fibrinogen) and clinical/echocardiographic parameters in CHF patients with different forms of AF.
- To explore the link between these markers and treatment in CHF patients.
Main Methods:
- A cross-sectional study of 99 CHF patients divided into three groups: sinus rhythm, paroxysmal/persistent AF, and permanent AF.
- Plasma CRP and fibrinogen levels were measured; echocardiography assessed left atrial dimension (LA), ejection fraction (LVEF), and right ventricular systolic pressure (RVSP).
Main Results:
- Mean CRP was significantly higher in permanent AF patients compared to sinus rhythm and paroxysmal/persistent AF groups.
- Permanent AF patients showed elevated fibrinogen, LA dimensions, and RVSP.
- CRP levels correlated with arterial hypertension and LA enlargement; fibrinogen correlated with CRP, permanent AF, and metabolic syndrome.
Conclusions:
- Elevated plasma CRP in CHF patients is associated with arterial hypertension and left atrial enlargement.
- Permanent AF and CRP levels are significantly linked to increased plasma fibrinogen in CHF patients.
Background:
Occurence of atrial fibrillation (AF) adversely affects left atrial size and cardiac function. This arrhythmia is also associated with an increase of plasma CRP and fibrinogen concentration. It is not clear whether elevated levels of inflammatory markers in patients with congestive heart failure (CHF) are associated with AF, clinical symptoms or adverse cardiac remodelling.
Aim:
To investigate the association between levels of inflammatory markers and selected clinical and echocardiographic parameters as well as used treatment in the population of CHF patients with various forms of AF.
Methods:
The cross-sectional study included 99 patients with CHF divided into 3 groups. Group I included patients with sinus rhythm. Group II consisted of patients admitted to hospital with AF and discharged with sinus rhythm (the category of paroxysmal and persistent AF). Group III comprised patients with permanent AF. In all patients plasma CRP and fibrinogen concentrations were measured and echocardiographic examination was carried out. Left atrial dimension (LA), ejection fraction (LVEF) and right ventricular systolic pressure (RVSP) were assessed.
Results:
Mean CRP concentration in group III (5.83+/-5.36 mg/l) was significantly higher than in group I (p=0.001) and group II (p=0.033). In the group with permanent AF mean fibrinogen concentration was elevated to a higher level (391.0+/-77.3 mg/dl) than in group II (p=0.007) and group I (p=0.099). Mean LA and RV dimensions and RVSP in group III were significantly higher than in group I and group II. Multivariable analysis revealed that plasma CRP concentration was significantly associated with the presence of arterial hypertension (p <0.001) and LA enlargement (p=0.007). A significant association between fibrinogen level and CRP level (p=0.038), presence of permanent AF (p=0.045) and metabolic syndrome (p <0.05) was found. Values of ln CRP were significantly correlated with LA diameter (r=0.24; p=0.015).
Conclusions:
Increased plasma CRP level in patients with CHF were significantly associated with arterial hypertension and LA enlargement. Permanent form of AF and CRP level have been shown to be significantly associated with increased plasma fibrinogen concentration in the course of CHF.
