Whether heart disease is hereditary depends on the specific type of heart disease. Some heart conditions are hereditary diseases, such as hypertrophic cardiomyopathy, which is an autosomal dominant inherited disease and can be inherited. Some heart diseases are related to genetics, such as coronary heart disease and dilated cardiomyopathy. These genetically related diseases significantly increase the risk of their offspring developing these conditions, but it does not necessarily mean that they will develop the disease, as environmental factors also play a crucial role. Of course, some heart diseases are not genetic, such as most congenital heart diseases, heart valve diseases, infective endocarditis, and myocarditis, which are not related to genetics.

What should be noted for rheumatic heart disease?

Rheumatic heart disease is caused by valvular pathology and often affects heart function. It is important to rest regularly, avoid overexertion, wear more clothing to prevent colds, and avoid exposure to cold winds. Each occurrence of a cold can exacerbate rheumatic heart disease. Dietary attention should focus on easily digestible, high-nutrient foods. Avoid consuming spicy and greasy foods, as they can lead to indigestion and gastrointestinal irritation, which can worsen symptoms of heart disease and increase the cardiac burden, bringing about adverse factors for the patient.

What does heart disease feel like?

Heart disease is a very common category of diseases in our daily lives, with a wide range of heart conditions. What are the general symptoms or feelings associated with heart disease? They often manifest in the following ways: First, palpitations or arrhythmias. Patients with arrhythmias often experience symptoms of palpitations, which are quite common. Second, chest tightness and chest pain, such as in coronary heart disease or hypertrophic cardiomyopathy. This type of heart disease often presents with symptoms of chest tightness and chest pain. Third, symptoms of heart failure, such as exertional dyspnea or nocturnal paroxysmal dyspnea. These symptoms are often indicative of heart failure. These three major categories are the most common symptoms of heart disease. If you experience any of these symptoms, be sure to visit the cardiology department of a hospital for a formal examination.

The cause of cor pulmonale

Cor pulmonale, also known as pulmonary heart disease, refers to the increased pulmonary vascular resistance caused by pathological changes in the bronchi, lung tissue, thorax, or pulmonary vessels, leading to pulmonary arterial hypertension and subsequent structural and functional changes in the right ventricle. This condition is clinically referred to as cor pulmonale. The causes of cor pulmonale can be divided into three main categories: The first category is diseases of the bronchi and lungs, such as chronic obstructive pulmonary disease (COPD), which accounts for approximately 80%-90% of cases. Other causes include bronchial asthma, bronchiectasis, severe pulmonary tuberculosis, interstitial pneumonia, and more. The second category involves diseases related to disorders of thoracic cage movement, such as various thoracic deformities, kyphoscoliosis, spinal tuberculosis, arthritis leading to extensive pleural adhesions, and deformities caused by thoracic plastic surgery. The third category includes pulmonary vascular diseases, such as pulmonary arterial hypertension, pulmonary thromboembolism, and other conditions leading to narrowing or blockage of pulmonary arteries, all of which can progress to cor pulmonale.

Is heart palpitations a heart disease?

Palpitations are one of the main symptoms of cardiovascular disease, but they should not be equated with it. Some palpitations do not accompany arrhythmias and can also occur in normal people, especially when lying on the left side, which might be noticeable. It is commonly seen in normal individuals who are nervous and sensitive, as well as in some anxious people. Normal people might experience palpitations during intense exercise; these could be due to sinus tachycardia or a high-output circulatory state, but most other cases should be evaluated to exclude heart disease.

Is pulmonary heart disease serious?

Cor pulmonale refers to the disease characterized by changes in the structure and function of the right ventricle due to increased pressure resistance in the pulmonary vessels, caused by abnormalities in the bronchopulmonary tissue, thoracic cage, pulmonary vessels, etc., ultimately leading to pulmonary arterial hypertension. Common symptoms of cor pulmonale observed clinically include coughing, production of phlegm, shortness of breath, chest tightness after activity, and difficulty breathing. Some individuals may experience respiratory failure and symptoms of heart failure. The severity of cor pulmonale depends firstly on the underlying causes of the disease. For instance, conditions like pulmonary embolism and pulmonary hypertension generally have a poorer and more serious prognosis. Secondly, extensive lung infections leading to a loss of cardiopulmonary compensation, resulting in respiratory failure and heart failure, typically indicate a more severe condition.
