What does the 'C' in the CHA2DS2-VASc score stand for?

  1. Chronic Kidney Disease

  2. Congestive Heart Failure

  3. Coronary Artery Disease

  4. Celiac Disease

The correct answer is: Congestive Heart Failure

The 'C' in the CHA2DS2-VASc score stands for Congestive Heart Failure. This scoring system is used to assess the risk of stroke in patients with atrial fibrillation. Congestive Heart Failure is included as one of the risk factors because patients with heart failure have structural heart changes and reduced cardiac output, which can increase their risk of thromboembolic events, including stroke. Identifying such risk factors enables healthcare providers to make informed decisions regarding anticoagulation therapy to mitigate the risk of stroke in these patients. In contrast, the other options listed do not specifically relate to the stroke risk evaluation that the CHA2DS2-VASc score addresses.
