Insights
Left ventricular diastolic dysfunction (LVDD) is not linked to the CHA2DS2-VASc score in patients experiencing non-hemorrhagic stroke and atrial fibrillation (AF). This finding suggests LVDD may not be a primary predictor in this patient group.
Area of Science:
- Cardiology
- Neurology
- Internal Medicine
Background:
- Atrial fibrillation (AF) is a common arrhythmia and a significant risk factor for stroke.
- The CHA2DS2-VASc score assesses embolic event risk and guides anticoagulant therapy.
- Left ventricular diastolic dysfunction (LVDD) is a potential complication in cardiovascular disease.
Purpose of the Study:
- To investigate the relationship between LVDD and the CHA2DS2-VASc score.
- To evaluate LVDD in patients with non-hemorrhagic stroke and concurrent AF.
Main Methods:
- Cross-sectional study of 76 patients with suspected non-hemorrhagic stroke and AF.
- Collected demographic, anthropometric, and clinical data.
- Calculated CHA2DS2-VASc scores and performed transthoracic echocardiograms to assess LVDD.
Main Results:
- The mean age of patients was 64.64 years; 36.8% were women.
- Hypertension was the most common comorbidity (65.8%).
- LVDD was present in 21.1% of patients and was not statistically associated with the CHA2DS2-VASc score (r = 0.151, P = 0.192).
Conclusions:
- LVDD is not associated with the CHA2DS2-VASc score in patients with non-hemorrhagic stroke and AF.
- This suggests that LVDD may not be a significant factor in predicting stroke risk based on the CHA2DS2-VASc score in this population.
Background:
Atrial fibrillation (AF) is the most common tachyarrhythmia and an important risk factor for thromboembolic stroke. CHA2DS2-VASc score was introduced for assessment of embolic events and as criteria for starting anticoagulants. This study was performed to evaluate the left ventricular diastolic dysfunction (LVDD) in patients with non-hemorrhagic stroke and AF.
Methods:
This cross-sectional study consisted of 76 consecutive patients with suspected non-hemorrhagic stroke referred to the Cardiology Department of Alzahra and Ayatollah Kashani hospitals in Isfahan, Iran, during 2015-2016. Demographic, anthropometric and clinical characteristics were evaluated for all patients at baseline. CHA2DS2-VASc score was calculated for all. All eligible patients underwent transthoracic echocardiogram (TTE) and LVDD was measured in the patients.
Results:
The mean age of the patients was 64.64 ± 5.95 years and 28 subjects (36.8%) were women. The most common underlying disease in the patients was hypertension (HTN) (65.8%). Median (range) CHA2DS2-VASc score was 4 (1-7). Four patients (5.3%) had paroxysmal AF and 16 cases (21.1%) had LVDD. Analysis showed that LVDD in patients with non-hemorrhagic stroke and coexisting AF was not associated with CHA2DS2-VASc score (r = 0.151, P = 0.192).
Conclusion:
LVDD is not associated with CHA2DS2-VASc score in patients with non-hemorrhagic stroke and coexisting AF.
