Clinical restrictive cardiomyopathy requires a lot of examination, which is categorized into physical examination, imaging examination and pathological examination. 1. Physical examination: during physical examination, patients with restrictive cardiomyopathy can usually be found to have signs of jugular vein angstroms, gallop rhythm on cardiac auscultation, low blood pressure, depressed edema of the lower limbs, hepatomegaly, and positive mobile turbidities through vision, touch, and percussion. 2. Imaging examination: pericardial calcification can be seen on X-ray, pericardial thickening can be seen on CT and CMR, and echocardiography can show bi-atrial enlargement and ventricular hypertrophy. 3. Pathologic examination: amyloidosis can be detected by pathologic examination to further confirm the diagnosis of restrictive cardiomyopathy. After the above tests, it is necessary to consult the doctor again for a clear diagnosis, and then according to the doctor’s instructions for targeted treatment to avoid delaying the condition.
