Patients who have a cold after cardiac stent surgery need timely medication under the guidance of the doctor, as well as rest and a light diet. Cardiac stent surgery, i.e. coronary stent implantation, is an important means of coronary heart disease treatment at present, and the technology is mature and has good therapeutic effect. If you have a cold after the stent surgery, you need to treat it in time, because upper respiratory tract infections will lead to an increase in myocardial oxygen consumption, which can easily cause angina or even heart attack. Such patients need to actively treat colds, and can take Chinese medicines such as cold and flu clearing heat granules and wind-cold and flu granules under doctor’s guidance for treatment. In addition, it is necessary to determine whether the cold is combined with bacterial infection, and if so, it should be promptly treated with appropriate antibiotics such as amoxicillin. Patients with colds after cardiac stent surgery need to rest, hydrate, and exercise appropriately to avoid overexertion induced angina or even heart attack.
