Can coronary heart disease cause dry cough?

Coronary heart disease generally refers to coronary atherosclerotic heart disease, which usually does not cause dry cough.

Coronary atherosclerotic heart disease is caused by atherosclerosis in the coronary arteries, causing stenosis of the blood vessel lumen and nasal congestion., leading to ischemic heart disease caused by local myocardial ischemia, hypoxia, and necrosis. Patients will mainly experience precordial or substernal crushing and contractive pain, etc., and may also experience shortness of breath, cold sweat, toothache and other accompanying symptoms, which do not cause dry cough.

Dry cough may be caused by the patient inhaling dust, exhaust gas, or being stimulated by cold air.
