The only blood test that I am aware of that could show evidence of heart disease would be a proBNP test. This protein increases when there is increased stress on the heart but there can be some false positives and a positive does not always mean heart failure or heart disease. When a veterinarian is suspicious of heart failure they may also recommend running a blood count and chemistry panel to help rule out infections and to check electrolytes and kidney values before starting treatment for heart failure.
