Answer:
Coumadin is prescribed for atrial fibrillation to thin the blood and prevent the formation of clots.
Explanation:
Atrial fibrillation is characterized by inadequate pumping of blood by the atria to the ventricle. Since,the atria are in a state of fibrillation or shaking, they cannot pump blood to the ventricles. This increases the risk of blood clots forming inside the atria that could potentially increase the risk of heart attack or stroke if the clots get lodged in the coronary or carotid arteries.
Coumadin is blood thinner that minimizes the aforementioned risks.
