Preventing and Reversing Atherosclerosis

NO FINANCIAL CONFLICT OF INTEREST

Objectives

• Show the prevalence of coronary artery disease in the United States

• Describe basic physiology of heart disease

• Discuss cardiac risk factors

• Discuss what we are doing at the Weatherhead P.E.T Center to detect, prevent, stabilize and reverse CAD

The Heart – 4” diameter, 6” long

• Over 80 year lifespan, the heart:

– Contracts 3.4 billion times

– Pumps 61 million gallons of blood

– Pumps its own blood supply-coronary flow

– Never rests, adapts to extreme demands

– Replaces its components (protein) every month

– Associated with coronation, strength, love, generosity, courage, stamina

The Heart Pumping Volume

• Over 80 year lifespan of the heart:

– Pumps 60 million gallons of blood

– Equals 8,020,000 cubic feet of blood

– Could fill container 10” deep, 100” wide, 8020’long (1.52 miles)

Cardiovascular Disease in U.S. facts

• 36% of all deaths (1 every 2.8)

• 1 Heart attack every 25 seconds

• 1 death every 36 seconds

• Only 18% of coronary attacks are preceded by long-standing angina

• Detection: non-invasive test

• Coronary Angiogram

• Revascularization therapy

How we fight coronary artery disease

Standard treatment: The Cascade

Coronary angioplasty and stents (PCI)

Bypass (open heart surgery)

Why it does not work

“The Good Physician treats the disease; The Great Physician treats the patient who has the disease.”

-William Osler

1849-1919

Why PCI/CAB do not prevent most heart attacks

or death

Why we do it

“My Doctor gave me six months to live,

but when I could not pay the bill,

he gave me six months more!” -Walter Matthau

Current evidence

• Intensive LDL lowering with statin therapy may induce plaque regression and further decrease CV events when compared with standard goals

• Can we do better?

Looking for the “silver bullet”?

• Current pills

• New pills

• Drugs to New targets

• New ways of delivering drugs

• Costs…

• Benefits…

• Are we missing anything?

• Do we need a different approach?

Lifestyle

Bad family history?

May not always be easy….

PHYSICAL ACTIVITY AND CARDIOVASCULAR DEATH

…but it is worthwhile…

PATIENTS AT THE CENTER OF HEALTH CARE

A Randomized Trial Of Integrated CAD Management By:

I. P.E.T. Imaging of the Heart

II. Medications To Goals

III. Healthy Lifestyle

Weatherhead Center for

Preventing and Reversing Atherosclerosis

University of Texas Medical School

•Target: 1300 participants

•Randomization:

Optimal standard of care or

Comprehensive risk factor management

•Follow-up: 5 years

•All participants: consult with study team every visit

•Risk factor assessment and consultation

•Electrocardiogram and exercise stress test

•3 blood tests for cholesterol, liver and kidney function (hsCRP)

•P.E.T. scan studies of the heart blood flow

•Diet evaluations and consultations

•Exercise consultation and risk factor modification with MD

•A service in addition to, NOT as an alternative to your MD optimal

medical care

All Century Patients will Receive:

•Can you participate in the study?

Study Entry Criteria

Documented Coronary Artery

Disease by

• Previous Heart Attack

• Angioplasty, Stent or

Bypass surgery

• History of Abnormal stress

test

Suspected or at Risk for Coronary

Artery Disease

•Diabetes and/or

•Multiple other CAD risk factors

with or without chest pain

symptoms

•Age >50

•Family history of CAD

•High total or LDL cholesterol

•High blood pressure

•Low HDL cholesterol

•Diabetes

•Cigarette smoking

•Coronary Calcification

Traditional Risk Factors for CAD

The final “take home” message for atherosclerosis prevention 2015

• A disease that YOU DO NOT HAVE TO HAVE

• Do not wait for symptoms or an abnormal stress test

• Do not expect others “to do it” for you

• We have to treat the patient who has the disease, not just the stenosis

• The “silver bullet” to win the battle against the #1 killer in U.S. is in risk factor modification by informed,

supported and motivated people!

Can intensive lifestyle changes prevent cardiovascular events and be

cost-effective?

“In a sense, this study is mainstream, but in another sense, it’s also 10

years ahead of its time. But it’s time 10 years from now becomes today!”
