Cardiogenic asthma is caused by left heart failure, usually with hypertension or various underlying cardiac diseases, and is most pronounced at night. In terms of treatment, the primary cause should be found first, because there are many diseases that cause cardiogenic asthma, such as hypertensive heart disease, coronary artery atherosclerotic heart disease, rheumatic heart disease and various other cardiomyopathies. If it is caused by hypertensive heart disease, the blood pressure should be controlled first, and if it is caused by coronary heart disease, the coronary artery engineering should be restored as early as possible, and the symptoms will be easily relieved when the primary disease is controlled. In addition, it is important to control infections, as they can exacerbate the symptoms of heart failure.
