Paolo Palange, Cor pulmonale – Cor pulmonale is a … idiopathic pulmonary fibrosis) and multiple pulmonary emboli, with the important, although small … [Article in Undetermined Language] The presence of peripheral edema in patients with chronic obstructive pulmonary disease was traditionally thought to herald the development of “right heart failure” as a result of pulmonary hypertension and right ventricular dilation. Mechanisms in pathogenesis Two basic mechanisms are involved in the pathogenesis of cor pulmonale. The right side of your heart pumps blood from your body into your lungs to get oxygen. Despite this frequency of chronic cor pulmonale, few publications have so far appeared on the prognosis [66], The principal obstacle to prognostic investigation lies in the difficulty of making an early diagnosis of pulmonary hypertension and, in particular, incipient hypertrophy of the right heart. Int J Chron Obstruct Pulmon Dis. [PATHOGENESIS OF COR PULMONALE]. PH is … Other mechanisms, such as hypoxic vasoconstriction and alveolar capillary compression in hyperinflated lungs can contribute to the rise of pulmonary arterial pressure during COPD exacerbations, exercise and sleep. All information is peer reviewed. International Journal of COPD 2007:2(3) 275 Chronic cor pulmonale in COPD The pulmonary vascular response to hypoxia is geneti-cally determined. Other etiologies include restrictive lung diseases (e.g. The first is alveolar hypoventilation, which From the Department of Pediatrics, University of Florida College of Medicine, Gainesville, Fla. Although “cor pulmonale” represents a leading cause of death in advanced COPD, there is no clear consensus on its definition. Would you like email updates of new search results? J Pediatr. Please enable it to take advantage of the complete set of features! "Pathophysiology of cor pulmonale in chronic obstructive pulmonary disease. The loss in pulmonary capillaries and the vascular remodelling, secondary to chronic hypoxia, cigarette-smoke exposition and systemic inflammation, are well known causes of endothelial dysfunction and pulmonary hypertension in COPD patients. -cor pulmonale is right ventricular hypertrophy that occurs as a compensatory response to chronically increased resistance to pulmonary arterial blood flow. 1970 Jul;22(7):783-94. Abstract: Although “cor pulmonale” represents a leading cause of death in advanced COPD, there is no clear consensus on its definition. However, this traditional view has been challenged. Left ventricular failure and cardiac dysrhythmias are not part of the pathogenesis of cor pulmonale. Affiliation:Department of Clinical Medicine, University of Rome “La Sapienza”, viale Università 37, 00185 Rome, Italy. Pulmonary hypertension has been traditionally considered the pathogenetic mechanism leading to right heart dysfunction in COPD, with peripheral oedema usually being attributed to the venous congestion secondary to the increase of right-ventricle filling pressure. In the pathogenesis of chronic cor pulmonale, particularly the type associated with chronic diffuse obstructive emphysema, there have been varying reports as to the magnitude of the cardiac output in these patients. Chronic cor pulmonale is defined as right-heart hypertrophy or right-ventricular dilatation and/or chronic right-heart failure, secondary to disorders of the respiratory system.  |  Med Arh. [Article in French] MORET PR. Chronic cor pulmonale involves the enlargement of the right ventricle as a result of pulmonary hypertension due to pulmonary disorders involving the lung parenchyma, bellows function, or ventilatory drive. Weitzenblum E, Schrijen F, Mohan-Kumar T, et al. NIH Cor pulmonale is right ventricular (RV) dysfunction caused by lung disease that results in pulmonary artery hypertension. Ashutosh K, Mead G, Dunsky M. Early effects of oxygen administration and prognosis in chronic obstructive pulmonary disease and cor pulmonale. Keywords: Pulmonary hypertension, vascular remodelling, lung hyperinflation, right heart dysfunction, Title: Pathogenesis of Chronic “Cor pulmonale” in COPD, Author(s):Paolo Palange and Patrizia Paoletti. Although “cor pulmonale” represents a leading cause of death in advanced COPD, there is no clear consensus on its definition. Most common form; Slow progression; Acute cor pulmonale. Sleep apnea 3. Part One.." American journal of respiratory and critical care medicine, 150(3), pp. Most cases of cor pulmonale are secondary to chronic obstructive pulmonary disease. The term “cor pulmonale” is still popular but there is presently no consensual definition and it seems more appropriate to define the condition by the presence of pulmonary hypertension (PH) resulting from diseases affecting the structure and/or the function of the lungs: PH results in right ventricular enlargement and may lead with time to right heart failure (RHF). Dirofilariasis may induce cor pulmonale in dogs, especially those with a history of exercise/work load, leading to right ventricular hypertrophy from increased cardiac outputs and increased pulmonary vascular resistance. Future studies are needed to clarify the possible role of “intermittent hypoxia”, elicited by exercise or sleep, on right heart function and also on sodium and water handling in COPD patients.
