Yesterday, I suddenly felt chest tightness and shortness of breath, accompanied by nausea and retchi

Chest tightness, shortness of breath and nausea and retching symptoms are generally considered to be caused by myocardial ischemia and heart failure, but also due to hypoglycemia, bronchial asthma, hypertension, anemia and other factors. You need to go to the cardiovascular department of the hospital in time for ECG, cardiac ultrasound, blood pressure and other examinations.
