what causes cardiac arteries to narrow
THURSDAY, Jan. 19 (HealthDay News) -- Millions of Americans have an undiagnosed artery disorder that can lead to high blood pressure, stroke and aneurysms, a new study reveals. The disorder is fibromuscular dysplasia, an accumulation of fibrous tissues in the arteries that causes them to narrow. The condition can occur in any artery but occurs most often in kidney or neck arteries. It affects close to 4 percent of Americans.
