Heart disease is caused by various factors that invade the heart, resulting in the loss of its normal physiological functions. Common causes of heart disease include rheumatic heart disease, congenital heart disease, viral myocarditis, coronary artery disease, and pulmonary heart disease. These diseases are considered organic heart diseases, caused by various reasons that lead to pathological changes in the heart's muscles, valves, etc., losing the heart's normal ability to pump blood and supply the body with blood.

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.

Can people with heart disease drink alcohol?

Patients with heart disease should not consume alcohol, especially those with severe heart conditions such as coronary heart disease, severe arrhythmias, and viral myocarditis. These patients especially should avoid alcohol as they need to use many medications during treatment. If they consume alcohol, the alcohol entering the body can chemically interact with some medications, leading to reduced efficacy, diminished effects, or causing side effects. Additionally, for these heart disease patients, consuming alcohol can increase the burden on the heart and exacerbate symptoms of heart disease.

Rheumatic heart disease etiology

Rheumatic heart disease is a type of organic heart disease, often caused by an abnormal immune response following a streptococcal infection, which affects the heart valves, resulting in valvular lesions, leading to stenosis or insufficiency, and posing significant risks to human health, severely impacting physical well-being. To prevent the occurrence of rheumatic heart disease, it is essential to actively control streptococcal infections, commonly including tonsillitis and upper respiratory tract infections. When a streptococcal infection occurs, effective antibiotics should be actively used to control the infection and reduce the incidence of rheumatic heart disease.

Symptoms of cor pulmonale

Cor pulmonale refers to a disease characterized by increased pulmonary vascular resistance due to pathologies of the bronchi, lung tissue, chest wall, and blood vessels of the lungs, leading to pulmonary arterial hypertension and structural and functional changes in the right ventricle. The common clinical symptoms of cor pulmonale include coughing, expectoration, shortness of breath, significant palpitations, and breathing difficulties after physical activity, reduced work capacity, and exacerbation of the above symptoms during acute infection phases. Some patients may experience chest pain and hemoptysis. The second set of symptoms relates to heart and lung function, manifesting during the decompensation phase. For instance, some patients may develop respiratory failure, and experience headaches, decreased appetite, drowsiness, significant edema in the lower extremities, and further symptoms such as arrhythmias, anorexia, abdominal distension, and nausea.
