What are the causes of asthma
summary
Cardiogenic asthma is a kind of paroxysmal asthma caused by left heart failure and acute pulmonary edema. Its clinical manifestations are similar to bronchial asthma. Patients with cardiogenic asthma had history of hypertension or heart disease, accompanied by frequent cough, cough, foam like, bloody sputum, heart enlargement, arrhythmia and abnormal heart sounds. Let's have a look.
What are the causes of asthma
Cardiogenic asthma is paroxysmal nocturnal dyspnea. The most prominent clinical manifestations were paroxysmal nocturnal dyspnea and cardiogenic asthma. Typical seizures often occur at night after 1~2 hours of sleep. The patient suddenly woke up with a sense of urgency and urgency. He was forced to sit up and open the window immediately, to relieve asphyxia, accompanied by cough, asthma breath sounds or cough like foam like sputum.
Extracardiac diseases, such as pulmonary embolism, cerebrovascular accident, inhalation of irritant gas, excessive intravenous rehydration, nephritis, renal failure, etc.
Left ventricular cardiomyopathy, such as coronary heart disease, acute myocardial infarction, congestive cardiomyopathy, hypertrophic cardiomyopathy, myocarditis, etc. 2. Left ventricular pressure overload, such as hypertension, aortic stenosis, obstructive cardiomyopathy, etc. 3. Left ventricular volume overload, such as aortic insufficiency, mitral insufficiency, some congenital cardiovascular diseases with left to right shunt (ventricular septal defect, patent ductus arteriosus, etc.).
matters needing attention
The disease mostly occurs in the elderly, usually due to hypertension, coronary heart disease and other causes of chronic heart failure. The light person takes the seat for more than 10 minutes to about 1 hour, the dyspnea can automatically subside, and the patient can fall asleep again. Severe cases of sustained attack, frequent cough, shortness of breath, cyanosis, sweating, cold hands and feet, cough up pink foam sputum, and can develop into acute pulmonary edema.
