Stroke is the fourth leading cause of death among Americans. Hospitalization and medical care immediately following a stroke are very costly, as is the rehabilitative care. So the question is how best to prevent a stoke or to help patients recover following a stroke.
The National Institutes of Health is conducting ongoing studies to determine ways of preventing strokes. Some of the most recent studies include:
— The use of dilation and stenting techniques similar to those used to unclog and open heart arteries has been proposed as a less invasive alternative to carotid surgery to remove the buildup of plaque within the carotid artery, which supplies blood to the head and neck. According to the NIH, carotid endarterectomy is considered the best treatment for preventing stroke and other vascular events. Stenting is a newer, less invasive procedure in which an expandable metal stent is inserted into the carotid artery to keep it open after it has been widened with balloon dilation. But the new NIH study found that the safety and effectiveness of the two procedures was largely the same. Following this study, doctors will have more options to tailor treatments for people considered at risk for stroke.
