Cardiomyopathy refers to a type of disease characterized primarily by organic changes in the myocardium, such as dilated cardiomyopathy, hypertrophic cardiomyopathy, and restrictive cardiomyopathy. These diseases are characterized mainly by pathological changes in the myocardium itself, forming a category of heart diseases. In contrast, coronary heart disease often refers to a type of heart disease caused by the narrowing of the coronary arteries due to atherosclerosis, leading to insufficient blood supply to the heart. Cardiomyopathy often manifests as damage to the myocardium, while coronary heart disease often manifests as blockage of the blood vessels. This is the fundamental difference between these two categories of heart diseases.

Can people with cardiomyopathy eat beef?

Patients with myocarditis can eat beef, but not too much. They should consume beef in small amounts. Beef is a type of meat with very high nutritional value, and it is a major source of high-quality protein, trace elements, and minerals for the human body. Eating beef regularly can improve the body's immunity and disease resistance. For patients with myocarditis, eating beef can help accelerate the repair of myocardial tissue. However, it is advisable not to eat fatty beef but instead choose lean meat and consume it in moderation. It is also important to pay attention to dietary structure, preferably eating easily digestible, high-protein nutritional foods, and increase the intake of vegetables and fruits, which can aid in the recovery from myocarditis.

Cardiomyopathy is divided into four types.

From a medical perspective, common cardiomyopathies are mainly divided into the following four categories: First, dilated cardiomyopathy, which refers to a type of cardiomyopathy characterized by significant enlargement of the heart, thinning of the ventricular walls, and declined heart function. Second, hypertrophic cardiomyopathy, which refers to a type of cardiomyopathy primarily characterized by thickening of the ventricular walls. Third, arrhythmogenic right ventricular dysplasia, a type of cardiomyopathy that is often clinically associated with episodes of ventricular arrhythmias. Fourth, restrictive cardiomyopathy, which is generally considered rare in clinical practice.

What is the prognosis of hypertrophic cardiomyopathy?

The prognosis of hypertrophic cardiomyopathy varies greatly, and it is the primary cause of sudden death in adolescents and athletes because it can progress to end-stage heart failure. Additionally, a small percentage may experience heart failure, atrial fibrillation, and embolism, but many patients have mild symptoms and can have a life expectancy close to normal. For the treatment of hypertrophic cardiomyopathy, adequate sudden death risk assessment and ICD prevention should be conducted. Because hypertrophic cardiomyopathy is the most common cause of sudden cardiac death in young people and athletes, an ICD can effectively prevent the occurrence of sudden death. Preventing high-risk factors, including previous cardiac arrest, one or more sudden deaths in first-degree relatives, severe left ventricular hypertrophy, and findings of repetitive non-sustained ventricular tachycardia on a 24-hour Holter monitor, low blood pressure during exercise, and unexplained syncope, especially during exercise, poses a high risk of sudden death in these patients.

Can myocarditis cause dizziness?

Cardiomyopathy is a fairly common disease in our daily lives. From a medical perspective, cardiomyopathy can usually be divided into dilated cardiomyopathy, hypertrophic cardiomyopathy, arrhythmogenic right ventricular dysplasia, and restrictive cardiomyopathy. When cardiomyopathy is present for a long time, it may cause a decline in the heart’s pumping function, leading to a reduction in cardiac output and resulting in heart failure. In such cases, due to insufficient blood supply to the brain, patients often experience symptoms of dizziness. If diagnosed with cardiomyopathy, under the guidance of a doctor, regulated medication can often significantly improve symptoms, including dizziness. (Specific medication usage should be conducted under the guidance of a doctor; do not self-medicate.)
