Chronic obstructive pulmonary disease (COPD) and heart failure both cause difficulty breathing. For people who have both COPD and heart failure, identifying the cause of breathing symptoms can be challenging.
Symptoms of COPD and Heart Failure
COPD and heart failure
cause the same main symptom: shortness of breath with exertion. People
with COPD, heart failure, or both, have a limited ability to exercise, climb stairs, or walk long distances. Difficulty breathing occurs for different reasons in COPD and heart failure.
People with COPD have difficulty exhaling all the air in their lungs because of lung damage -- often from years of smoking.
When it takes longer to exhale completely, it’s hard to increase the
rate of breathing. Most people with COPD breathe comfortably while
resting. During exertion, though, breaths start coming in before air
from the last breath has been exhaled, and shortness of breath results.
In people with heart failure, the heart does not pump blood
efficiently. As in COPD, most people with heart failure can breathe
easily when at rest. With activity, blood flow must increase, and the
heart must pump harder and faster. If the heart can’t keep up, blood
“backs up” into the lungs. This fluid congestion causes shortness of
breath.
COPD and Left-Sided Heart Failure
Heart failure in the left ventricle is the most common form of heart failure. Left-sided heart failure is most often caused by high blood pressure
or coronary artery disease. COPD and left-sided heart failure are not
directly related. However, the two conditions may influence each other.
For example, low oxygen in the blood from COPD may put excess strain on
the heart, worsening left-sided heart failure. Excess fluid in the lungs
from heart failure can make breathing even more difficult for someone
with COPD.
COPD and Right-Sided Heart Failure
Severe COPD can cause heart failure in the heart’s
right ventricle, a condition called right-sided heart failure or cor
pulmonale. In severe COPD, oxygen concentration in the blood falls to
abnormally low levels. In response, the walls of the main blood vessels
inside the lungs (pulmonary arteries) change. The blood pressure inside
these arteries goes up, as well. This is one type of a condition called pulmonary hypertension.
The heart’s right ventricle pumps blood through the
pulmonary arteries into the lungs. High blood pressure in the pulmonary
arteries puts excess strain on the right ventricle. Over time, the right
ventricle may become stretched and dilated, and fail to pump blood
effectively.
Right-sided heart failure causes fluid to accumulate in the body, such as in the legs and abdomen. Many conditions other than COPD also cause pulmonary hypertension and right-sided heart failure.
I think we are just about there, the referral to the thoracic surgeons at Notre Dame Hospital is almost in my hands. I remain calm and detached. I feel good. I will not be surprised by anything once I get the referral. The surgeons might not want to help out an ex smoker. I might not have the genetic makeup they need. Those things will not matter if they happen. It will just be the way things go. However, having gone this far I would be mightily disappointed if I did not at least make it far enough to meet those good doctors at Notre Dame Hospital.
