Pulmonary Manifestations of Heartworm Disease

Veterinary Clinics of North America: Small Animal Practice, 1985
The clinical signs associated with heartworm disease are the result of changes in the pulmonary arterial system. These clinical signs are the result of either pulmonary hypertension or lung parenchymal disease associated with vascular changes. An increase in pulmonary arterial pressure produces an increase in right ventricular afterload, which may lead

Angiocardiography in Canine Heartworm Disease

American Journal of Veterinary Research, 1970
SUMMARY To study heartworm disease (Dirofilana immitis), angiocardiograms (acg) and radiograms were made of 34 infected and 14 normal dogs. Comparison was made of normal and abnormal selective right and left ventriculograms. The following successive phases seemed to be characteristic of the disease and were cumulative: a) Linear lucencies (adult ...

Treatment of dogs with severe heartworm disease

Veterinary Parasitology, 2020
Fortunately, the majority of dogs diagnosed with heartworm infection are asymptomatic (or have only mild symptoms such as intermittent cough) and go through adulticide therapy without complication. Complications occurring with heartworm infection and during its treatment most often directly reflect the pulmonary vascular and parenchymal injury ...

Right Ventricular Enlargement in Heartworm Disease

American Journal of Veterinary Research, 1977
SUMMARY The size of the right ventricle of 15 dogs with spontaneous Dirofilaria immitis microfilaria was evaluated by thoracic radiography, electrocardiography, and right ventricular free wall weights. Based on electrocardiography and right ventricular weights, none of the 15 dogs had evidence of right ventricular hypertrophy.

Susceptibility of Dogs with Heartworm Disease to Hypoxia

American Journal of Veterinary Research, 1977
SUMMARY Dogs with Dirofilaria immitis microfilariae and early radiographic pulmonary artery changes, but without pulmonary hypertension or clinical signs of heartworm disease, were studied. An exaggerated pulmonary hypertensive response was found in these dogs if subjected to 10% inspired oxygen.

Feline Heartworm Disease

2018
Dirofilaria immitis infection in cats is a recognized clinical problem with increasing incidence and public awareness. Heartworm disease in cats has been reported worldwide and is consistently diagnosed in heartworm endemic areas. There are three methods which have been used in the diagnosis of feline heartworm disease: immunofluorescence tests for ...

Clinical Significance of Feline Heartworm Disease

Veterinary Clinics of North America: Small Animal Practice, 1998
The clinical signs and diagnostic approach are different in the cat as compared with the dog, which has impaired the veterinarian's ability to detect this parasite in the cat. New techniques and methodologies have enabled the cat owner and veterinarian to recognize this potentially severe disease.

Heartworm disease in canines

Theoretical and Natural Science
Heartworm disease is a parasitic disease caused by Dirofilaria immitis that affects the pulmonary arteries in canines, causing circulatory disturbances and breathing difficulties. The disease is transmitted through mosquito bites and the worms mature in the heart, lungs, and associated blood vessels of canines.
