Normal Heart Function and Changes
That Can Occur in Scleroderma
Amit R. Patel MD, FACC
Associate Professor of Medicine and Radiology
Director Cardiac MRI and CT
Scleroderma |
Goals of Presentation
• To review the normal heart function
• To discuss heart problems that can occur in people with scleroderma
• To briefly review cardiac tests that are commonly used to evaluate heart disease

Why We Need a Heart
3
The best and most beautiful things in the world cannot be
seen or even touched. They must be felt with the heart.
Helen Keller
The heart of a fool is in his mouth, but
the mouth of a wise man is in his heart.
Benjamin Franklin
The less you open your heart to others, the more your
heart suffers.
Deepak Chopra
I think there is only one quality worse than
hardness of heart and that is softness of head.
Theodore Roosevelt
To wear your heart on your sleeve isn't a very good
plan; you should wear it inside, where it functions best.
Margaret Thatcher

Scleroderma |
The Heart is Actually 2 Pumps: Right and Left Ventricles
7
• Heart beats 60-100 times a minute
or >30million times per year
• Pumps 4-8 liters of blood per
minute or >2million liters per year
• Heart does >25million Joules of
work per year
• Left ventricle creates systemic blood pressure
of 90-140mmHg
• Higher because blood has to get to entire body
• Right ventricle creates pulmonary artery blood
pressure of 15-30mmHg
• Lower because blood only has to pump through
air filled lungs
Scleroderma |
The Heart has 2 “Filling” Reservoirs to Collect Blood: The Atria

Controlling the Direction of Blood Flow: Heart Valves

Powering the Heart Muscle: Coronary Arteries and Microvasculature
11

Changes that Occur with Exercise
12
Heart Function While Sitting Heart Function While Running
• Heart rate increases
• Blood pressure increases
• Heart pumps “harder”
• Energy requirements go up
• Oxygen requirements go up
• Blood flow to heart muscle
increases 5-8x above normal!

The Coronary Arteries and the Microvasculature

Impact of Coronary Heart Disease in the United States
Coronary heart disease is
responsible for 1 of every 6
deaths in the United States.
Each year approximately 785,000
Americans will have a new
coronary attack and 470,000 will
have a recurrent attack.
Cost of cardiovascular disease
>$175 billion per year.
Approximately 900,000 stents
implanted each year.
Approximately 500,000 patients
undergo bypass surgery each
year.

Other Cardiac Problems in Scleroderma
• Heart rhythm problems
– Fast atrial arrhythmias
– Fast ventricular arrhythmias
– Slow heart rhythms (heart

• Scarring of the pericardium
(lining of the heart)
• Heart valve problems
