It can be difficult to distinguish animals with heart failure from those with respiratory disease because of the similarity in clinical signs, physical examination findings, and sometimes even radiographic changes. In addition, some animals suffer from heart and lung or airway diseases concurrently, although in most situations one clinical disease predominates as the cause for clinical signs. It is also important to understand that the presence of disease in one organ can lead to secondary disease in the other thoracic organ. Disorders of the respiratory tract that cause clinical complaints similar to those found in cardiac disease include asthma in cats and bronchitis in dogs, and pneumonia, pulmonary edema, and interstitial diseases in both species. In addition, respiratory or systemic causes of pleural effusion must be distinguished from hydrothorax due to biventricular heart failure.
