Post-maintenance is very important to reduce the risk of cardiovascular events (angina pectoris, myocardial infarction, stent implantation, bypass).
Quitting smoking (including second-hand smoke) is a very important part of measures to maintain vascular patency. Why do doctors always tell patients to quit smoking over and over again?
The harmful substances in the smoke will make the vascular endothelium rough, and the gap between them will increase, which will lead to the easy entry and deposition of lipid components in the blood, which will be swallowed up by mononuclear macrophages to form foam cells, form plaques and cause vascular blockage.
Harmful substances in smoke can also affect endothelial function, leading to vasospasm, decreased blood supply and angina pectoris. In severe cases, persistent vasospasm can lead to acute myocardial infarction. In addition, vasospasm can cause shear stress changes, leading to plaque rupture, thrombosis, and then lead to myocardial infarction.
After cardiac stent implantation, continuous smoking will affect stent endothelial coverage and easily lead to thrombosis or restenosis in stent.
Compared with non-smokers, people who continue to smoke after angioplasty have a higher incidence of chest pain and a worse quality of life. Therefore, after cardiac stent implantation, you must quit smoking, including second-hand smoke. Quitting smoking can greatly improve the benefits of surgery and prevent the recurrence of cardiovascular events, which means a better quality of life and ways to relieve chest pain.
Pay attention to healthy cardiovascular Dr. Xu!
Today, many people who have received or will receive cardiovascular and cerebrovascular stent implantation are constantly entangled in whether to smoke or not. As a user of cardiovascular stents, after consulting many cardiologists, I will tell you this: cigarettes are not only harmful to many aspects of the human body, but more importantly, they are the initiator of cardiovascular and cerebrovascular diseases.
When I was doing the stent, through coronary angiography, the doctor told me that most of my three cardiovascular vessels were blocked by 95%, and the lighter ones were blocked by 75%, all of which were among the stents. Not only is the blood vessel blocked, but through other tests, the doctor also told me that my heart blood vessels have calcified-this is a bit serious!
The doctor asked me: Do you know why your cardiovascular system is in this state? This has a lot to do with your long-term bad lifestyle! One is the big fish and meat and cholesterol on the wine table, which enter the blood vessels as fat and attach to the blood vessel walls, becoming garbage that blocks blood vessels.
The second is long-term smoking. As a result of smoking, the garbage attached to these blood vessel walls becomes calcified plaques. Over time, these plaques accumulate until your blood is cut off and your engine is paralyzed! Remember, many diseases, such as myocardial infarction, which seem to be emergencies, are actually related to the accumulation of long-term bad living habits.
Therefore, you should not have any illusions about cigarettes. It doesn't even bother to pretend to be a painted skin. Direct is an out-and-out demon!
The harm of smoking to the cardiovascular system is obvious and well known. It's not that smoking is not good after installing a heart stent. But it may be necessary to install a bracket, which is caused by smoking. Even if the stent is installed, keep pumping, and it may be necessary to install the stent in a few years.
Harm of Smoking to Cardiovascular System Smoking will produce more than 4,000 kinds of chemicals, among which nicotine, cigarette tar, carbon monoxide and heavy metals are the most harmful substances leading to coronary heart disease.
On the one hand, these harmful substances damage vascular endothelial cells, leading to endothelial dysfunction and lipid peroxidation, thus promoting the production of vascular plaques. On the other hand, smoking can easily lead to plaque instability and lead to acute myocardial infarction.
The risk of myocardial infarction of smokers is 6 times that of non-smokers, and the age of myocardial infarction is earlier than that of non-smokers 10 years.
We can imagine what it would be like to continue smoking with a bracket. 1. After installing the stent, the quality of life has not improved.
2. Not long after, the blood vessel was blocked again, or the stent was blocked.
Conclusion: Cardiac stent is an effective and commonly used method to treat coronary heart disease. There are more and more patients with heart stents around us. I believe that it is very unlikely for patients who have not implanted a heart stent, but what harm will it do if they smoke again after implanting a heart stent?
1. Can I smoke again after stent implantation?
After stent implantation, we must have coronary heart disease. Lifestyle intervention, especially smoking cessation treatment, is very important for patients with coronary heart disease, because smoking will not only increase the incidence of coronary heart disease, but also increase the probability of stent thrombosis or stenosis after cardiac stent implantation. Therefore, smoking is definitely not recommended after cardiac stent implantation. However, smoking is the same as a high-fat diet, and smoking won't kill you because of smoking a cigarette. The same is true of high-fat diet, which won't directly kill you because you eat more meat, but smoking, like high-fat diet, will directly or indirectly lead to complications and recurrence of coronary heart disease. Therefore, patients with stent implantation should repeatedly emphasize the importance of quitting smoking.
Second, the harm of smoking is not just that?
In fact, the harm of smoking is well known, and even the words "smoking is harmful to health" are printed on the production and packaging of tobacco, so the harm of smoking is self-evident, but the harm of smoking to health is not only to increase the incidence of coronary heart disease and the probability of blockage after stent implantation. Smoking also increases the risk of lung diseases, such as chronic obstructive pulmonary disease and lung cancer, as well as oral diseases, digestive diseases, arteriovenous diseases and other complications. The harm of smoking is so great that even without a heart stent, we are advised to reduce smoking and give up smoking.
Third, it is not enough to quit smoking after stent implantation?
After stent implantation, it needs long-term or even lifelong good drug compliance, so it is very necessary to carry out secondary prevention of drugs, otherwise the probability of restenosis or blockage in the stent will greatly increase! Of course, lifestyle intervention includes not only smoking, but also abstinence from alcohol, moderate exercise and weight control. So it is not enough to quit smoking after stent implantation. On the premise of other lifestyles, it is necessary to carry out good secondary prevention and treatment of drugs to reduce the related complications after stent implantation.
You got it? Pay attention to us, and updated popular science is pushed to you every day.
Smoking will not only damage coronary endothelial cells, but also lead to coronary heart disease; It will also increase the risk of stent stenosis or even blockage that has been implanted in the heart!
Smoking is an important risk factor for the occurrence and development of coronary heart disease, which is not only the knowledge in books, but a living example of many patients with coronary heart disease who both lose money and earn money.
Dr. Zhang, I have been working in the front line of interventional therapy for heart disease all the year round, and I have found the harm of smoking in many cases of coronary heart disease and even acute myocardial infarction. Here are two examples.
Just four days ago, I treated a young man who was only 35 years old in the emergency room. Sudden and severe chest pain at night, ECG at admission suggests myocardial infarction, and my emergency coronary angiography suggests coronary circumflex artery occlusion! Immediate stent implantation opened the blocked blood vessel.
Asking about medical history, this young patient has no hypertension, diabetes or family history of coronary heart disease. The only risk factor is smoking, smoking more than 2 packs a day!
Last year, I treated an old man with unstable angina pectoris. Coronary angiography showed stenosis and stent implantation was performed.
The patient's symptoms improved obviously, but only after half a year, the old man was hospitalized again because of angina pectoris. The re-examination of coronary angiography showed that the original stent had restenosis! Only stent implantation can be performed again.
After the operation, according to the family, the old man was addicted to smoking, and he still smoked dry every day after the first stent. This time, I must "scare" him to stop smoking. The old man also realized the harm of smoking and said that he would give up smoking completely. So far, the elderly are in good health and have no symptoms of angina pectoris.
Smoking is not necessarily the whole factor of the occurrence and development of coronary heart disease, but it is definitely one of the most important factors.
According to relevant research data, smoking will increase the incidence of coronary heart disease by 3 to 4 times and the probability of acute myocardial infarction by 20%! Quitting smoking in patients with coronary heart disease can reduce the mortality rate by about 30%.
Finally, dr. zhang wants to say that there are some beneficial and harmless things that may not exist in this world; But some things are harmful, smoking is one thing.
Patients with coronary heart disease install stents because the coronary artery is severely narrow or occluded, which can not provide enough blood supply for the heart, so stents are needed to expand the narrow blood vessels and open up a way for the survival of the heart. After installing stents, can patients with coronary heart disease eat whatever they want once and for all, such as smoking, and do whatever they want? Of course not. Next, medical experts will analyze what harm smoking will bring to patients with coronary heart disease after installing stents.
What kind of heart burden will smoking bring to patients with coronary heart disease? (1) damages the endothelial cells of coronary artery and accelerates the arterial lesion.
The harmful substances produced by smoking will damage our coronary endothelial cells. When coronary endothelial cells are damaged, it will aggravate coronary atherosclerosis and plaque formation, cause or aggravate coronary artery stenosis, and induce angina pectoris and myocardial infarction under the stimulation of various pathogenic factors in the body.
(b) Endothelial cells are damaged and hypertension occurs.
Our endothelial cells produce a substance called nitric oxide, which can relax blood vessels. However, after smoking damages vascular endothelium, it will reduce the production of nitric oxide, make blood vessels contract and raise blood pressure. After the blood pressure rises, it will also accelerate the development of coronary atherosclerosis, aggravate coronary artery stenosis, and induce angina pectoris and myocardial infarction.
(3) Increased adrenaline secretion aggravates myocardial ischemia.
The harmful substances produced by smoking will increase the secretion of adrenaline in human body. After the adrenaline secretion increases, it will accelerate the heartbeat, increase the burden on the heart, cause myocardial ischemia and hypoxia, and induce angina pectoris when the coronary artery is severely narrowed.
What effect will smoking bring after installing the stent? Many friends with stents have such luck: my coronary artery is no longer narrow and I can do whatever I want. Is that really the case? Of course not. The vascular lesions of patients with coronary heart disease become diffuse lesions, that is to say, all coronary arteries have lesions, but some places have more severe stenosis and some places have less stenosis. Stenting only widens the place where the lesion is the most serious and the blood vessel is the narrowest, and the lesions in other places still exist. After the stent is installed in time, it is still necessary to change the lifestyle and cooperate with regular drug treatment to prevent the aggravation of coronary artery disease and reduce the chance of restenosis at the stent implantation site. As we mentioned before, smoking will cause a series of damage to coronary artery: smoking will damage coronary endothelial cells, which will increase the risk of coronary atherosclerosis and plaque formation by 2-6 times. Therefore, if you don't quit smoking after installing the stent, new vascular stenosis or restenosis will appear at the stent, which will increase the risk of myocardial infarction again.
To sum up, smoking can damage coronary endothelial cells, increase blood pressure, accelerate coronary atherosclerosis and plaque formation, increase adrenaline secretion, accelerate heartbeat, increase heart burden and aggravate myocardial ischemia and hypoxia. If you don't quit smoking after installing stents, it will continue to aggravate coronary artery disease and even restenosis at the stent implantation site. Therefore, it is suggested to quit smoking after installing stents to reduce coronary artery injury. Thanks for reading!
First, we need to understand why stents are implanted in the coronary arteries of the heart. This is because of two things:
1. Acute myocardial infarction, and some serious complications, such as cardiogenic shock, heart failure and various malignant arrhythmia. Only by opening the occluded coronary artery and restoring the blood supply to the myocardium can the dangerous consequences of the above complications be alleviated.
2. When coronary atherosclerosis is aggravated, a large number of plaques will be formed, which will lead to severe stenosis of coronary artery lumen and insufficient blood supply to myocardium, which will affect the quality of life of patients and bring more pain to patients. For patients with frequent angina pectoris, stent can make the narrow coronary artery unobstructed, restore the blood supply of ischemic myocardium, improve the quality of life of patients, and prevent the rupture of unstable soft plaque from causing myocardial infarction.
Coronary atherosclerosis is often a risk factor for patients with various cardiovascular diseases, such as family history of early-onset cardiovascular and cerebrovascular diseases, long-term heavy smoking, hypertension, high cholesterol, anemia and diabetes. In addition, people who are irritable and competitive sympathetic nerve excitement often secrete too much catecholamine in their blood, which is also an important factor leading to atherosclerosis, and can even cause coronary artery spasm to rupture atherosclerotic plaques, cause myocardial infarction or induce rapid death.
Atherosclerosis caused by these cardiovascular risk factors is by no means limited to a certain part. In addition to infarction and severe stenosis, arterial vessels that must be stented often have diffuse plaques of different severity. If the above risk factors are not well controlled, atherosclerotic plaques will continue to increase, and the stenosis of vascular lumen will still be aggravated, so the possibility of plaque rupture and myocardial infarction still exists. Statins and antihypertensive drugs must be taken after stent implantation. If we only take drugs without paying attention to changing the unhealthy lifestyle in the past, especially smoking, cardiovascular events will happen again.
When smoking, dozens of harmful substances such as nicotine, nitric oxide and tar are inhaled from the lungs. These components will cause inflammatory lesions in the intima of arteries, accelerate the progress of atherosclerosis, make atherosclerotic plaques grow faster, larger and more unstable, promote platelet aggregation, and induce arterial vasoconstriction and even spasm, which will not only aggravate the formation and development of atherosclerotic plaques, but also cause myocardial infarction or cerebral infarction due to the huge shear force generated by arterial vasospasm. Nicotine can induce myocardial electrophysiological disorder and even produce fatal ventricular fibrillation.
Therefore, the incidence of coronary heart disease and myocardial infarction in smokers will increase by 3-4 times and 20%, and the mortality rate is significantly higher than that in non-smokers. Cerebral hemorrhage and cerebral infarction are 3.75 times and 3.73 times that of non-smokers. If patients with coronary heart disease quit smoking, the mortality rate can be reduced by 36%; Taking statins and other drugs reduces cholesterol and mortality by 29%; Taking beta blockers or ACEI drugs, the mortality rate dropped by 23%. Comparatively speaking, if people with coronary heart disease want to reduce mortality, quitting smoking will bring the greatest benefits.
Do you want to continue smoking when you see patients with coronary heart disease or patients with stents here?

Even if you don't put the bracket, there are disadvantages.
Smoking is closely related to chronic obstructive pulmonary disease. The most obvious harm of smoking is respiratory system, including cardiovascular and cerebrovascular diseases, such as oral cavity and digestive system. In addition, we must realize the harm of smoking to family members and people around us, especially the harm of second-hand smoke.
I don't smoke, but I can't object to smoking. Only when friends come over for tea or mahjong, will I open the window in advance. Occasionally, when playing mahjong or drinking, the noise will be very loud, and you can't open the window for ventilation. I have to buy an air purifier, because I will feel dizzy if I smell smoke for a long time, and I will open the window as soon as my friends leave.
Try to smoke less or not or stay away from smokers. Smoking is one of the important pathogenic factors of lung cancer, and the risk of lung cancer is ten times that of non-smokers.
The concentration of harmful substances inhaled by passive smokers is not lower than that of smokers. In the cold smoke exhaled by smokers, the contents of smoke tar, benzopyrene and carbon monoxide are more than those inhaled by smokers, so most cancer patients caused by smoking are passive smokers.
Put the stent, still don't quit smoking, to put it bluntly, I don't think there is anything wrong with it, smoke! I don't know what the benefits are. Maybe it's a pleasure for smokers.
You can't smoke without a bracket, let alone a bracket.
Many friends who have finished the stent are just like you, and they can't live without it.
The harm of smoking to people is subtle, bit by bit, quietly.
Angina pectoris and myocardial infarction are transient. When you feel sick, you must say that you will never smoke again. After the stent was released, it was not difficult to feel, and I started smoking again. Typically, the scar forgets the pain.
In fact, smoking is the chief culprit of vascular stenosis in a sense. If you don't smoke, you may not put a bracket, at least not now.
Smoking can increase coronary heart disease by 3 to 4 times; The probability of acute myocardial infarction increased by 20%, and the mortality rate was significantly higher than that of non-smokers.
When you take aspirin and clopidogrel, you can prevent blood vessels from clogging again and prevent stent restenosis. Smoking a cigarette, constantly adding dirty things to the bracket.
See if the smoke is strong and the medicine is useful; One by one, like a tug of war.
You are playing games with your health and even your life.
Smoking will not only increase your risk of placing stents again, but also have other hazards.
If patients with coronary heart disease quit smoking, the mortality rate can be reduced by 36%.
Smoking is about 4 times that of non-smoking stroke;
Quitting smoking at different ages can prolong life. Quitting smoking at the age of 30/40/50/60 can lead to life expectancy of 65,438+00/9/6/3 years respectively.
Smoking is the most fundamental cause of cardiovascular and cerebrovascular diseases and cancer at present. Tens of millions of people die of cardiovascular and cerebrovascular diseases and cancer every year.
Is it really that hard to quit smoking?
Dr. Xiao Wang is also a member of China Tobacco Control Association and has been engaged in smoking cessation activities. He is willing to make friends with you and pay attention to heart health together. )
Smoking after cardiac stenting has great disadvantages. It can even be said that the reason why the heart is a stent may be caused by smoking.
If the same two people need heart stent surgery for the same reason. After finishing, both of them recovered well and the effect was satisfactory. After recovery, one of them couldn't control himself and continued his old habit-smoking. Then from then on, the two men developed in different directions. Maybe after a few years, non-smokers are all right and stable. Smokers may have changed their heart stents again, or have new symptoms.
Therefore, through the above example, we can know that we must not smoke after heart stent implantation, and we should not be happy for a while and suffer for a lifetime. In fact, these shortcomings are easy to understand. People who smoke know that they breathe smoke into their lungs and then spit it out. Instead of turning around in your mouth, it has an impact on your lungs. The lungs are covered with capillaries leading to the heart. In other words, the blood in these blood vessels passes through the stent. Moreover, the blood vessels are permeable, and the smoke sucked into the lungs and turned around must have an impact on the blood vessels. Even if it is smoked, it will be blackened and inelastic.
To sum up, don't smoke after cardiac stenting, take care of yourself.
