Cor pulmonale is usually chronic but may be acute and reversible. . This forces the right ventricle to work harder to pump blood. Pulmonary heart disease, also known as cor pulmonale, is the enlargement and failure of the right ventricle of the heart as a response to increased vascular resistance (such as from pulmonic stenosis) or high blood pressure in the lungs.. Cor pulmonale usually presents chronically, but there are 2 main conditions can cause acute cor pulmonale: a massive pulmonary embolism, which is more common, and acute respiratory distress syndrome (ARDS). Cor pulmonale causes the right ventricle to enlarge and pump blood less effectively than it should. Causes. Subsequent definitions have described pathologic aspects of the right ventricle, such… For full details of the review protocol, see appendix A. This disorder is not caused by heart disease; it is a lung condition that affects the right ventricle of the heart. 2 Cor Pulmonale Treatment. Cor pulmonale causes the right ventricle to enlarge and pump blood less effectively than it should. Cor pulmonale is a heart condition which causes the right-hand side of the heart to fail. The treatment for Cor Pulmonale depends on the underlying condition that acts as the cause. Cor pulmonale is also known as right-sided heart failure because the right ventricle becomes enlarged and eventually stops working. Cor pulmonale can range in severity from mild functional changes in the right ventricle to complete failure of the right side of the heart. Cor pulmonale describes impairment in right ventricular function as a result of respiratory disease, leading to increased resistance to blood flow in the pulmonary circulation. However in clinical practice, by far and away the predominant causes of cor pulmonale are: Chronic obstructive pulmonary disease (COPD) (e.g., emphysema, chronic bronchitis) in the chronic setting. Cor pulmonale results from a disorder of the lung or its vasculature; it does not refer to right ventricular (RV) enlargement secondary to left ventricular (LV) failure, a congenital heart disorder (eg, ventricular septal defect), or an acquired valvular disorder. The main reason is that right heart catheterization (RHC) cannot be performed on a large scale in patients at risk. Cor pulmonale is defined as an alteration in the structure and function of the right ventricle (RV) of the heart caused by a primary disorder of the respiratory system. Right-sided heart failure; Pulmonary heart disease. Cor pulmonale is a condition that most commonly arises out of complications from high blood pressure in the pulmonary arteries (pulmonary hypertension). Cor Pulmonale. Cor pulmonale is a condition that occurs when the right ventricle of your heart cannot pump properly. Cor pulmonale is enlargement and thickening of the ventricle on the right side of the heart resulting from an underlying lung disorder that causes pulmonary hypertension (high pressures in the lungs). The right ventricular hypertrophy that occurs in chronic cor pulmonale is a direct result of c … The ventricle is then pushed to its limit and ultimately fails. PH is high blood pressure in the arteries of your lungs. The disease causes the right ventricle to enlarge and prevents it from pumping blood efficiently. Long-term high blood pressure in the arteries of the lung and right ventricle of the heart can lead to cor pulmonale. Such diseases can increase blood pressure in the blood vessels of the lungs. Causes of Condition. Cor pulmonale refers to right-sided heart failure. In this case, the treatment is to reduce resistance to blood flow in the pulmonary circulation. Also, it is usually regarded as complication of acute respiratory distress syndrome, in which the poor mechanical ventilation is to blame.
