Smoking after stenting not only causes damage to the respiratory system, but also aggravates the damage to the endothelial cells of the coronary arteries, which may lead to restenosis of the coronary arteries, so smoking is not recommended.
On the one hand, smoking after stenting causes a certain degree of damage to the respiratory system, and the harmful substances in the smoke irritate the respiratory tract, leading to a decrease in the immune function of the respiratory tract, changes in the structure of the lungs as well as in the lung function, and increasing the chances of bronchitis, emphysema, pulmonary heart disease, and even lung cancer.
On the other hand, tar, nicotine and other harmful ingredients in smoke will cause a certain degree of damage to the endothelium of blood vessels, and the initiating factor of atherosclerosis is the damage to the endothelium of blood vessels, and smoking will aggravate the development of atherosclerosis, and even coronary artery stenosis may occur again. Harmful ingredients such as nicotine will stimulate the cardiac nervous system and affect the contraction and conduction of the heart.
To summarize, smoking cessation is strongly recommended after stent implantation.
