The most common cause of cardiogenic dyspnea is myocardial ischemia due to coronary artery disease, which is not treated regularly and systematically, and heart failure will occur when the disease develops and worsens. Myocardial infarction is also a type of coronary artery disease, and heart failure occurs after myocardial infarction, which is one of the most common causes of cardiogenic dyspnea. Other common causes compared to coronary artery disease are myocarditis or cardiomyopathy, which can lead to heart failure as the disease progresses, such as viral myocarditis and dilated cardiomyopathy. There are also diseases such as hypertension, pulmonary hypertension, valve stenosis or incomplete closure that can increase the workload of the heart and overload it, which can also lead to heart failure and cardiogenic dyspnea in the long run. Other congenital heart disease, such as ventricular septal defect, ductus arteriosus, chronic anemia, hyperthyroidism, etc., will also increase the burden on the heart and develop into heart failure, which is also one of the causes of cardiogenic dyspnea.
