What is cor pulmonale and how is it diagnosed?
Cor pulmonale is right ventricular enlargement secondary to a lung disorder that causes pulmonary artery hypertension. Right ventricular failure follows. Findings include peripheral edema, neck vein distention, hepatomegaly, and a parasternal lift. Diagnosis is clinical and by echocardiography. Treatment is directed at the cause.
How does cor pulmonale affect the heart?
Right-sided heart enlargement and heart failure (cor pulmonale). In cor pulmonale, the heart's right ventricle becomes enlarged and has to pump harder than usual to move blood through narrowed or blocked pulmonary arteries. As a result, the heart walls thicken and the right ventricle expands to increase the amount of blood it can hold.
What are the treatment options for cor pulmonale?
Treatment strategies for cor pulmonale include supplemental oxygen, assisted mechanical ventilation, digoxin, and diuretics. Pulmonary vasodilator compounds should be used with caution because they can compromise gas exchange in cor pulmonale from secondary pulmonary hypertension. Trials with digoxin and inotropic agents have been evaluated.
Can a blood clot cause cor pulmonale?
Yes. There is acute and chronic cor pulmonale. Acute cor pulmonale – This condition is most often associated with a pulmonary embolism, which is caused by a blood clot to the main artery of the lung. A pulmonary embolism can be caused by deep vein thrombosis (DVT) which is a blood clot that forms in a deep vein in the leg.

How do you treat cor pulmonale?
Treatment strategies for cor pulmonale include supplemental oxygen, assisted mechanical ventilation, digoxin, and diuretics. Pulmonary vasodilator compounds should be used with caution because they can compromise gas exchange in cor pulmonale from secondary pulmonary hypertension.
What causes right sided heart failure?
The damaged right side stops pumping efficiently, and blood builds up in the veins. As pressure increases in the veins, it pushes fluid into surrounding tissues. The fluid buildup causes swelling and congestion throughout your body.
Can cor pulmonale be cured?
Cor pulmonale is a serious heart condition that develops as a complication of advanced lung disease. Because there is no treatment that can reverse cor pulmonale, prevention is key.
What is the prognosis for cor pulmonale?
The overall five-year survival rate for cor pulmonale complicating COPD is approximately 50%. Long-term oxygen therapy improves this and the best prognostic indicator is the pulmonary arterial pressure. Prognosis also appears to be significantly improved by smoking cessation and correct use of LTOT/NOT.

Cor pulmonale is a Latin word that means "pulmonary heart," its definition varies, and presently, there is no consensual definition.
What is the initial pathophysiologic event in the production of cor pulmonale?
The initial pathophysiologic event in the production of cor pulmonale is an elevation of pulmonary vascular resistance. As the resistance increases, the pulmonary arterial pressure rises, and the right ventricular work increases leading to right ventricular enlargement (e.g., thickening, dilation, or both).
What percentage of heart disease is caused by cor pulmonale?
Cor pulmonale is estimated to account for 6% to 7% percent of all types of adult heart disease in the United States. The incidence of cor pulmonale is widely variant among countries. It depends on air pollution, the prevalence of cigarette smoking and other risk factors for various lung diseases.
What is normal pulmonary vascular resistance?
Normal pulmonary vascular resistance is approximately one-tenth of the resistance of the systemic arteries. Chronic hypoxemia leading to chronic vasoconstriction produces smooth muscle proliferation in small pulmonary arteries. Hypoxemia produces changes in vascular mediators such as Nitric Oxide, Endothelin1 (ET1) and platelet-derived growth factors (PDGF A and B). Nitric oxide is a vasodilator; hypoxemia reduces endothelial cell production of nitric oxide and results in impaired smooth ms relaxation.

Which side of the heart is affected by a dilated right ventricle?
As this condition develops, the right ventricle becomes dilated (widened) and thickened, and later the right atrium may be affected as well. 2 . The right atrium receives deoxygenated blood from the left side of the heart and sends it to the right ventricle, which pumps blood to the lungs through the pulmonary artery.
What is the most common cause of cor pulmonale?
Massive pulmonary embolism. Also known as a heart attack. This is the most common cause of acute cor pulmonale. It often can look like a myocardial infarction or a disturbance to the muscle tissue within the heart. Massive pulmonary embolism refers to a type of clotting that starts in your legs and arteries and travels to your lungs. These lung clots then cause pulmonary hypertension due to the effort the heart must make to pump the clotted blood in and out of your lungs.
