After cardiac stenting, you should eat a light diet, take your medication on time and in the right amount, and supplements are not recommended. Cardiac stenting is generally a treatment for the recanalization of blood vessels due to narrowing or blockage of the lumen caused by coronary atherosclerosis. Although the diseased blood vessels have been recanalized, the atherosclerosis of the blood vessels still exists, and obstruction may reoccur if no attention is paid. Therefore, it is necessary to eliminate the bad lifestyle after cardiac stenting, quit smoking, prohibit alcohol, and eat a light diet. Supplements contain a lot of nutrients, such as rich vitamins, calcium, phosphorus, magnesium, but there may also be a lot of sugar and fat; some medicated supplements metabolized by the liver will also increase the metabolic burden on the liver, resulting in liver damage or aggravate the toxicity of the drug itself, which is not conducive to coronary artery recovery, and may aggravate the coronary arteriosclerosis, so it is not recommended to take supplements. The most important thing after cardiac stenting is to take oral medication on time and in accordance with the dosage, so that the exposed cardiac stent quickly realize endothelialization, to prevent thrombus formation again. If there is discomfort after stenting, it is recommended to consult a doctor as soon as possible to avoid delaying the condition.
