This condition can lead to, Cor pulmonale, or pulmonary heart disease, occurs in 25% of patients with chronic obstructive pulmonary disease (COPD). Cor pulmonale is a medical condition where the right ventricle of the heart becomes enlarged due to a disease in either the lungs or the lung's blood vessels, which are called the pulmonary vessels. A contributing factor is chronic hypoxia, which stimulates erythropoiesis, thus increasing blood viscosity. In cor pulmonale, there is an accentuation of the pulmonic component of the second heart sound. The World Health Organization (WHO) defined cor pulmonale in 1963 as, “ hypertrophy of the right ventricle (RV) resulting from diseases affecting the function and/or the structure of the lungs except when these alterations are the results of diseases which primarily affect the left side of the heart or congenital heart disease ”. CHRONIC COR PULMONALE Emmanuel Weitzenblum T he term “cor pulmonale”is still very popular in the medical literature,but its definition varies and there is presently no consensual definition. To compensate, the heart will thicken its right ventricle (which pumps blood to the lungs) and expand the chamber so it can hold more blood. Create an account to start this course today.

It's a serious condition that can damage the right side of the heart. credit by exam that is accepted by over 1,500 colleges and universities. Definition Cor pulmonale, or pulmonary heart disease, is right ventricular enlargement with or without right heart failure resulting from pulmonary hypertension caused by structural or functional abnormalities of the pulmonary circulation.1 “Cor pulmonale” may be used for right heart enlargement from all causes of pulmonary hypertension… A study among 226 patients with ARDS revealed cor pulmonale in 22% (95% CI, 16% to 27%).

Cor pulmonale is estimated to cause approximately 5% to 7% of all types of heart disease in adults, and chronic obstructive pulmonary disease (COPD) due to chronic bronchitis or emphysema is the causative factor in more than 50% of people with cor pulmonale. Observe if the patient has difficulty in maintaining breath while the history is taken. Cor pulmonale is a condition that causes the right side of the heart to fail. - Definition, Therapy Techniques & Positions, What Is Pulmonary Edema?

These patients all had other abnormalities that could have resulted in the oedema, notably primary salt retention by failing kidneys (creatinine levels 676 [micro]mol/l, 1 276 [micro]mol/l and 168 [micro]mol/l respectively). It causes increases in pulmonary resistance, and as the right side of the heart works harder, the right ventricle hypertrophies.
