Final answer:
The maximum chad-vasc score is 9, indicating the highest risk of stroke. The stroke percentage varies based on the score, with higher scores indicating higher stroke risk.
Step-by-step explanation:
The chad-vasc score is used to assess the risk of stroke in patients with atrial fibrillation. It evaluates various risk factors such as congestive heart failure, hypertension, age, diabetes, stroke history, vascular disease, and gender. The maximum chadvasc score is 9, which indicates the highest risk of stroke.
Stroke percentage refers to the likelihood of experiencing a stroke based on the chadvasc score. The percentage varies depending on the score:
- A score of 0: Very low stroke risk (less than 1%)
- A score of 1: Low stroke risk (about 1.3%)
- A score of 2: Moderate stroke risk (about 2.2%)
- A score of 3 or higher: High stroke risk (ranging from 3.2% to 18.2%)
