Atrial Fibrillation-Arrhythmia 200x150
Heart disease, also known as coronary artery disease or cardiovascular disease, describes a range of conditions that affect the heart, especially those that involve narrowed or blocked blood vessels. As plaque builds up in the walls of the arteries, a condition known as atherosclerosis, the arteries narrow, making it more difficult for blood to flow and creating a risk for heart attack, stroke or other heart complications. Approximately once every 34 seconds, heart disease strikes someone in the United States. It is the No. 1 cause of death in the world and the leading cause of death in the United States, killing almost 380,000 Americans a year.

Memorial Hermann is proud to partner with the American Heart Association, whose mission is to build healthier lives, free of cardiovascular diseases and stroke.
