Heart disease in cattle with clinical signs of heart failure: 59 cases.

This retrospective study identified clinical signs, underlying cardiac conditions, blood findings, echocardiographic findings, and prognosis for 59 cattle with clinical signs of congestive heart failure. Signalment; history; clinical signs; clinicopathologic, echocardiographic, and radiographic findings; and treatment were determined by reviewing medical records. Follow-up information was obtained by telephone conversation with owners. Most patients were tachycardic (n = 50), and tachypneic (n = 55). Pericarditis of traumatic origin (n = 21), by extension from pleuritis (n = 3), or of idiopathic origin (n = 1) was diagnosed in 25 cases. Other diagnoses were congenital heart defect (n = 13), cardiomyopathy (n = 9), bacterial endocarditis (n = 7), and neoplasm (n = 5). Twelve cases (20%) were discharged. Long-term survival was good in 2 out of 3 cases treated by pericardiostomy. The prognosis is poor in cases of heart failure in cattle and deaths within 1 mo (n = 3) or between 1 to 3 mo after discharge (n = 3) were common in cases for which follow-up was available (n = 8).
