In general, dilated cardiomyopathy can eat chocolate, but need to strictly control the amount of consumption. Dilated cardiomyopathy is a kind of heterogeneous cardiomyopathy, which is mainly characterized by biventricular or left ventricular enlargement accompanied by systolic dysfunction. Although the specific cause of the disease is still unclear, or related to infections, non-infectious inflammation, poisoning, metabolism and endocrine disorders and other reasons, but it does not have a lot to do with chocolate, so the patients are usually allowed to eat chocolate. However, because chocolate contains more fat and carbohydrates (nutritional research found that every 100g of chocolate contains 40.1g of fat and 53.4g of carbohydrates), excessive consumption may cause obesity, so patients with dilated cardiomyopathy need to strictly control the intake of chocolate. Patients with dilated cardiomyopathy have a high mortality rate if left untreated. In order to prolong the survival time of patients, they should actively cooperate with professional doctors for treatment.
