I always feel short of breath. Is it myocardial ischemia?

The symptoms of shortness of breath may be caused by myocardial ischemia or pneumonia or asthma.

When the patient has continuous myocardial ischemia, the heart beats compensatory, resulting in increased myocardial oxygen consumption. When myocardial oxygen consumption is greater than oxygen supply, the patient often has symptoms of shortness of breath. Secondly, when the patient has pneumonia, asthma and other diseases, bronchospasm during the attack may also cause the patient to feel shortness of breath.

If the patient often has symptoms of shortness of breath, it is recommended to go to the hospital as soon as possible for physical examination, chest CT examination, ECG examination, cardiac color Doppler ultrasound, coronary angiography, etc. to make a clear diagnosis.
