Canine heartworm disease causes significant pulmonary abnormalities, even in asymptomatic cases. This study aimed to compare the chest radiographs of cases infected with with those of heartworm-negative dogs. Fifteen animals treated at a private veterinary clinic in the municipality of Maricá, Rio de Janeiro, underwent chest radiography, regardless of their serological status, for the presence of antigen, and none of them used preventive measures. Eight dogs tested positive for the antigens on immunochromatographic tests (8/15, 53.3%). When the radiographs of the two groups of dogs were blindly compared, the increase in the caudal pulmonary arteries showed a strong positive correlation (0.732) with infection using the Spearman correlation test. These results suggest that heartworm infection, even in the absence of clinical signs, elicits caudal lobar pulmonary artery enlargement that can be detected on radiography.
犬心丝虫病会导致严重的肺部异常，即使在无症状的病例中也是如此。本研究旨在比较感染心丝虫的犬只与未感染心丝虫的犬只的胸部X光片。在里约热内卢州马里卡市的一家私人兽医诊所接受治疗的15只动物，无论其血清学状态如何，均接受胸部X光检查以检测抗原，且它们均未采取预防措施。8只犬在免疫层析试验中抗原检测呈阳性（8/15，53.3%）。当对两组犬只的X光片进行盲法比较时，使用Spearman相关性检验发现，尾侧肺动脉增粗与感染呈强正相关（0.732）。这些结果表明，即使没有临床症状，心丝虫感染也会引起尾叶肺动脉增粗，这可以通过X光检查检测到。
