Cardiovascular Disease

• The #1 killer of Americans

• Approximately 1,000,000 deaths annually

• An American dies from cardiovascular disease every 30 seconds

• More than any cancer– 2-3 times more than any single (lung) cancer– Almost more than all cancer deaths combined

vascular

Vascular Disease

• Abdominal aortic aneurysm (AAA)

• Carotid artery disease

• Peripheral arterial disease (PAD)

Vascular Disease

• Abdominal Aortic Aneurysm (AAA)– An aneurysm is a ballooning of the

aorta. As the vessel gets larger, like a balloon it can rupture!

– Aortic aneurysm rupture is the 10th leading cause of death in men over 50.

– More than 15,000 people die needlessly each year in this country from the rupture of an aortic aneurysm.

Vascular Disease

• Carotid Artery Disease – Vascular disease can block the

carotid arteries to the brain and cause paralyzing strokes.

– Stroke is the third leading cause of death in this country and the leading cause of permanent disability among older Americans.

– More than $50 billion is spent annually on the care of stroke patients.

Vascular Disease

• Peripheral Arterial Disease (PAD)– Vascular disease can block circulation to

the legs, leading to serious disability. – Between 25 and 30 million people over 70

years of age have peripheral arterial disease (PAD).

– PAD begins by simply limiting the amount you can walk, but when it worsens it could lead to gangrene and leg amputation.

– Even people with mild PAD are three times as likely to die of heart attacks and strokes as those without the disease.

The AVA is a Foundation within SVS.

Its goal is to increase public awareness of vascular disease.

American Vascular Association

The AVA is a public health advocacy organization whose mission is to reduce death and disability due to vascular disease.

AAA - Men & WomenAAA - Men & Women

• There is significant undiagnosed noncardiac vascular disease in a broad segment of our population.

• 30% - 50% of patients with vascular disease are not receiving treatments that might be significantly beneficial.

• There is a significantly higher prevalence among women than has been historically reported.

• Women receive a significantly lower intensity of treatment.

• There is significant opportunity for patient and physician education with the potential for measurably improved outcomes.
