Since brain tissue does not regenerate, the loss of cells in the affected area is permanent. According to the National Stroke Association, about 730,000 Americans suffer a new or recurrent stroke each year. About four million Americans are living with some type of impairment due to stroke. One-third of these patients are believed to be seriously impaired. Atrial Fibrillation and Stroke One of the risk factors for stroke is a condition called atrial fibrillation.
Atrial fibrillation is a rapid, abnormal heart rhythm of the two upper chambers.
Patients may experience heart palpitations, fatigue, dizziness, and a feeling of breathlessness. Researchers estimate that more two million American adults have atrial fibrillation. In some cases, the symptoms are very mild and patients are diagnosed through routine exams. However, even in mild cases, atrial fibrillation can have serious consequences. Atrial fibrillation is now recognized as a leading risk factor for stroke.
