Diagnostic criteria for cor pulmonale

Pulmonary heart disease refers to cardiac dysfunction caused by lung diseases. The diagnostic criteria for pulmonary heart disease include the following: 1. The patient must have a history of chronic lung disease, such as chronic obstructive pulmonary disease (COPD), emphysema, etc. 2. The patient must exhibit symptoms of cardiac dysfunction, such as dyspnea, fatigue, palpitations, etc. 3. Electrocardiogram (ECG) should show electrophysiological abnormalities of the heart, such as ventricular hypertrophy, atrioventricular conduction block, etc. 4. Echocardiography should reveal structural and functional abnormalities of the heart, such as ventricular dilation and reduced contractile function. 5. Pulmonary function tests should demonstrate the presence of lung disease, such as decreased pulmonary function and increased airway resistance. Therefore, the diagnosis of pulmonary heart disease requires comprehensive evaluation of both pulmonary and cardiac pathophysiological changes.
