Pulmonary heart disease, commonly known as pulmonary heart disease, is divided into acute pulmonary heart disease and chronic pulmonary heart disease, of which, chronic pulmonary heart disease is more common. The symptoms of chronic pulmonary heart disease are mainly coughing, shortness of breath, dyspnea, dry and wet rales in the lungs on auscultation, and in severe cases, even hypoxia, carbon dioxide retention, accompanied by intermittent epigastric distension, vomiting, occasional venous anger, and possibly accelerated heart rate when climbing stairs, and if accompanied by kidney disease, it may cause edema and ascites, and if left untreated, it is likely to lead to shock. Acute pulmonary heart disease is caused by pulmonary vascular embolism due to high pressure of the aorta causing respiratory distress, followed by myocardial ischemia due to imbalance of oxygen supply to the heart, or even right ventricular failure, and in some patients, the thrombus is dislodged and enters the pulmonary artery causing embolism, which may also form acute pulmonary heart disease, which may cause chest pain, accompanied by occasional dizziness and nausea. In summary, pulmonary heart disease is a lung disease caused by multiple vascular embolism, which can lead to palpitations, chest tightness, irritability, and even headache and nervous disorder, and needs to be treated promptly, otherwise it may drag on to become chronic, with appropriate chest expansion exercises, reducing the intake of fats and cholesterol, and ensuring a relaxed mood to prevent the disease.
