Shortness of breath after cardiac stenting is usually caused by myocardial ischemia, myocardial infarction, heart failure, neurosis, etc. Drugs such as furosemide, metoprolol, deacetyl furfuryl glycoside, etc., can be used, or coronary angiography can be performed again.
1. Myocardial ischemia: stent implantation in some patients does not completely relieve the obstruction of all blood vessels, and will be affected by microcirculatory dysfunction, so the postoperative period will still be due to myocardial ischemia resulting in chest tightness and shortness of breath, you can use drugs such as metoprolol to control the heart rate and reduce the oxygen consumption of the myocardium, and nitrate drugs such as nitroglycerin to expand the coronary arteries.
2. Myocardial infarction: if myocardial ischemia for a long time can occur myocardial infarction, if the occurrence of large myocardial infarction can be obvious shortness of breath and other symptoms, you need to immediately seek medical treatment to take coronary artery angiography, such as the condition of the need to be placed in the stent again, or bypass surgery.
3. Heart failure: If the patient has heart failure, even after stenting, edema and shortness of breath may still occur due to heart failure, and medications to improve heart failure, such as furosemide and deacetyl furfuryl glucoside, etc., need to be used.
4. Cardiac neurosis: belongs to the autonomic balance disorder, can appear shortness of breath, chest tightness, insomnia, panic and other symptoms, usually with anxiety, emotional excitement and other mental triggering factors, preferably in menopausal women, if necessary, can take lorazepam, escitalopram and other drugs.
It is recommended that patients after cardiac stent surgery regular review, actively cooperate with the doctor with medication, to avoid blindly use their own medication.
