Cardiopulmonary function was examined in 18 dogs with serious chronic heartworm disease showing ascites, subcutaneous edema, prostration, weakness, jaundice and so on. After surgical heartworm removal from the pulmonary arteries, 10 dogs recovered (surviving group), and 8 dogs died or were euthanatized because of poor prognosis (nonsurviving group). The number of live heartworms residing in the pulmonary arteries of the surviving group tended to be larger than that in the nonsurviving group. At necropsy, severe pulmonary arterial lesions such as thromboembolism including dead heartworms, proliferative and villous lesions and intimal hyperplasia were noticed in all dogs examined, and tended to be severer in the nonsurviving group. Heartworm-coiling around the tricuspid valve chord was found in 1 dog of the surviving group and 4 dogs of the nonsurviving group. Before heartworm removal, there was no significant difference in the mean pulmonary arterial pressure (MPAP) between the surviving and nonsurviving group. Right atrial pressure (v-wave) was higher, and the cardiac index (CI) was lower in the nonsurviving group. Arterial oxygen tension was lower in the surviving group than in the heartworm-free group, and it was lower in the nonsurviving group than in the surviving group. Carbon dioxide tension was lower in the surviving group than in the heartworm-free group. Bicarbonate concentration (HCO3-) was lower both in the surviving and nonsurviving groups than in the heartworm-free group. One week after heartworm removal, MPAP decreased (P less than 0.05), and CI and HCO3- tended to increase in the surviving group.
