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.

How to relieve vomiting caused by heart disease?

Treatment for vomiting caused by heart disease must depend on its cause. First, if caused by heart failure, as the symptoms of heart failure worsen, including right-sided heart failure, patients may experience nausea, vomiting, and bloating after eating. The key in these cases is to correct heart failure, perhaps with intravenous diuretic medications or the newer diuretic drug tolvaptan, which can alleviate symptoms of vomiting caused by heart failure. Secondly, digoxin toxicity can cause vomiting if patients with heart failure are taking too much or have been on digoxin for a prolonged period. The primary action in these instances is to discontinue the digoxin medication promptly. Thirdly, if associated with gastritis, treatment would involve medications to stop vomiting and oral omeprazole to protect the stomach lining. (Medications should be taken under medical supervision.)

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.

How is cor pulmonale treated?

Cor pulmonale refers to the disease characterized by increased pulmonary vascular resistance due to pathological changes in the bronchi, lung tissue, thorax, or pulmonary vessels, leading to pulmonary arterial pressure and subsequently causing changes in the structure and function of the right ventricle. When cor pulmonale occurs, treatment is generally divided into the acute exacerbation phase where active control of infections, clearing of the airways, improvement of respiratory function, correction of hypoxia and carbon dioxide retention, control of respiratory failure and acute heart failure, and management of complications are emphasized. During the chronic remission phase, the goal is to enhance the patient's immune function, eliminate triggering factors, reduce or avoid the occurrence of acute exacerbations, and partially or fully restore cardiopulmonary function.

Manifestations of Cor Pulmonale

Cor pulmonale refers to a disease characterized by changes in heart structure and function due to increased pulmonary vascular resistance caused by pathological conditions of the bronchi, lungs, thoracic cage, or pulmonary vessels, leading to pulmonary arterial hypertension. This condition is collectively known as cor pulmonale. The clinical manifestations of cor pulmonale generally develop slowly. Clinically, in addition to pulmonary and pleural symptoms, there gradually appear signs of pulmonary cardiac failure and damage to other organs. Common symptoms include coughing, expectoration, palpitations, dyspnea, fatigue, decreased endurance to physical activity. In the decompensated stage, symptoms such as worsening dyspnea, headaches, insomnia, decreased appetite, and even some signs of right heart failure like palpitations, poor appetite, abdominal bloating, nausea, and swelling of the lower limbs may occur.
