Do you have high cholesterol or high blood pressure? Have members of your family suffered from these ailments? Do you have a poor diet? If you answer “yes” to any of these questions, you may want to consider being screened for your risk of stroke through the services of Life Line Screening. Life Line Screening uses ultrasound technology to view the plaque build-up in your carotid arteries, the main arteries that carry blood to the brain. Blockages in these arteries are a leading cause of stroke.
