Can cor pulmonale with emphysema

Bronchial asthma than simply easier to develop into chronic bronchitis and emphysema cor pulmonale. But often attacks, the continued state of asthma, especially with chronic bronchitis, emphysema and develop into a pulmonary heart disease situation is not uncommon. Bronchial asthma due to cramps, mucosal edema and increased secretion, airway obstruction, when inspiratory, strong contraction diaphragm, rib muscle on the question, thorax expansion, increasing negative pressure within the chest, alveolar expansion, lung expansion , on the whole thorax showed pulmonary emphysema state. In asthma, emphysema no clinical manifestations. But if regular asthma attack, bronchial mucosal edema recurrent respiratory formed lasting narrow. Bronchodilator inspiratory gas alveolar able to enter, when bronchial narrowing breath, depression, patent, not gas from the lungs, alveolar residual volume increased flexibility damaged, thus creating obstructive pulmonary emphysema. In chronic obstructive pulmonary emphysema on the basis of the increase with emphysema, pulmonary pressure increased, oppression alveolar capillary wall, which luminal stenosis or occlusion, and alveolar rupture, pulmonary capillary bed much less pulmonary circulation resistance increased, in pulmonary hypertension. Followed, chronic obstructive ventilatory dysfunction and hypoxic pulmonary artery spasm, thereby increasing the pulmonary vascular resistance and pulmonary hypertension, resulting in a vicious cycle, to right ventricular hypertrophy and dilated right heart failure.
