cor

 [kor] (L.)
cor adipo´sum a heart that has undergone fatty degeneration or that has an accumulation of fat around it.
cor bovi´num a greatly enlarged heart resulting from a hypertrophied left ventricle.
cor pulmona´le a serious cardiac condition in which there is right ventricular heart failure due to pulmonary hypertension secondary to disease of the blood vessels of the lungs. Acute cor pulmonale is an emergency situation arising from a sudden dilatation of the right ventricle as a result of pulmonary embolism. Chronic cor pulmonale develops gradually and is associated with such chronic obstructive pulmonary diseases as emphysema, silicosis, and pulmonary fibrosis following an infection. These conditions impair pulmonary circulation and thus create a “damming” effect on the blood flowing through the pulmonary artery. This in turn slows down the flow of blood from the right ventricle, and the ventricle becomes hypertrophied and dilated.

Signs and symptoms are similar to those of congestive heart failure from other causes: dyspnea, edema of the lower extremities, enlargement of the liver, and distention of neck veins. The hematocrit is increased as the body attempts to compensate for impaired circulation by producing more erythrocytes.
Treatment. Treatment may involve use of drugs to decrease pulmonary vascular resistance, pulmonary embolectomy, or even lung transplantation. More traditional treatments have included administration of bronchodilators and use of a mechanical ventilator to reduce hypoxia and dyspnea. For treatment of the heart failure, see heart failure.

heart

(hart), [TA]
A hollow muscular organ that receives the blood from the veins and propels it into the arteries. In mammals it is divided by a musculomembranous septum into two halves-right or venous and left or arterial-each of which consists of a receiving chamber (atrium) and an ejecting chamber (ventricle).
