“According to data from the Global Adult Tobacco Survey (GATS) China, there are 300 million smokers in China, of whom nearly 53 per cent are men. Every year, 1 million people die from smoking-related diseases, accounting for 12% of all deaths. Smoking is the white plague of modern society, significantly increasing the chance of malignant tumors, respiratory diseases, strokes, and ischemic heart disease. The incidence of coronary heart disease among smokers and passive smokers is 3.5 times higher than that of non-smokers, the death rate is 6 times higher, and the incidence of myocardial infarction is 2-6 times higher. The incidence of myocardial infarction is 2-40 times higher. 30-40% of people who die of cardiovascular diseases are related to smoking. Tobacco smoke contains more than 4000 kinds of chemical substances, more than 250 kinds of toxic and harmful substances, of which more than 60 kinds of substances have carcinogenicity, nicotine is the main substance causing addiction. Secondhand smoke has a higher concentration of many carcinogenic and toxic chemicals compared to the smoke inhaled by the smoker himself. Nicotine, carbon monoxide, oxygen free radicals, polycyclic aromatic hydrocarbons and butadiene in tobacco smoke are directly linked to damage to the cardiovascular system. Smoking can even cause cardiovascular patients to die up to seven years earlier. Smoking has seven cardiovascular sins! Zhang Yajun, director of VIP center of Shanghai Yuanda Cardiothoracic Hospital and expert in cardiology, explained that when people smoke, they will inhale a large amount of nicotine, which contains toxic substances into the human body will have an impact on the cardiovascular endothelial system, lipids and blood clotting function, which in turn triggers hypertension, hypercholesterolemia, arteriosclerosis, sudden death of cardiogenic origin, coronary heart disease and other cardiovascular diseases. “Overall, smoking on the cardiovascular has ‘seven major sins’, once the blood vessels become ‘black’, many problems will come uninvited.” First, prompting elevated blood pressure After smoking, due to increased secretion of adrenaline and norepinephrine, which can make the heart beat faster and blood pressure rise. Second, cause atherosclerosis As the saying goes, “people live with their arteries”, if the arteries have problems, the heart, brain, kidneys and other organs of the whole body will be affected, once the consequences of the blockage is unimaginable, heart attack, cerebral infarction, renal embolism, intestinal embolism will come one after another. Third, induce sudden death coronary heart disease patients smoking, may prompt the occurrence of ventricular fibrillation, which is the most important cause of sudden death. Fourth, lead to thromboembolic vasculitis The more you smoke, the more severe the vasculitis. Fifth, prompting the formation of blood clots, easy to lead to thrombosis Thrombosis can occur anywhere in the blood vessels, thrombus with the blood flow in the blood vessels, if the blockage is the coronary artery blood vessels of the heart, it will induce myocardial infarction. Sixth, reduce the body’s ability to sense the aura of heart disease Nicotine will inhibit the body’s normal sense of pain, affecting people’s heart disease “alarm” – angina pectoris perception, resulting in sudden infarction or even sudden death. Seventh, the impact of blood lipids, blood glucose There is a large amount of evidence that cardiovascular disease is the first diabetic “critical illness”, impaired blood glucose is the same as a direct injury to cardiovascular and cerebrovascular health. Smokers suffer from coronary heart disease risk increased three times! In addition, the impact of smoking on the heart is also reflected in the age of 30-49 years of age of male smokers, the incidence of coronary heart disease than non-smokers is about three times higher than the incidence of smoking, and smoking is also caused by angina pectoris attack and sudden death of an important cause. Prof. Zhang Yajun said that carbon monoxide produced during smoking will reduce the ability of red blood cells to carry and transmit oxygen by about 20%, thus triggering a series of cardiovascular system diseases. Smoking can also cause endothelial dysfunction, increase thrombosis, aggravate atherosclerosis and increase the risk of angina pectoris. Nicotine, or nicotine, can cause damage to the vascular lining, vasoconstriction, elevated blood pressure, accelerated heart rate, coronary artery spasm will induce angina pectoris and myocardial infarction. The risk of hypertension and coronary heart disease in long-term smokers is much higher than that of non-smokers. In addition, passive smoking will also significantly increase the risk of coronary heart disease. So, how to effectively quit smoking? First, tell others First of all, smokers can tell people around you to quit smoking, which can reduce the chance of smoking, and take the initiative to avoid smoky environments, such as bars, etc.; In addition, Prof. Zhang Yajun emphasized that medical personnel, especially respiratory and cardiologists, should be the first to quit smoking. Smoking by medical staff, especially in front of patients, will inevitably reduce the effectiveness of persuading smokers to quit. Imagine how much confidence a doctor who smokes while counseling patients or who smells of tobacco can give to patients who want to quit smoking. Second, the doctor example to persuade the community, schools, hospitals, doctors take the initiative to teach, smokers take the initiative to understand the hazards of smoking and the benefits of smoking cessation knowledge, as much as possible with detailed data to illustrate, or with some of the smoking is harmful to health for the public common knowledge of the celebrity events or iconic events, or with the patient around the example to persuade; doctors can use the time of the patient’s visit to the case of the dangers of smoking and smoking cessation may be able to benefit from. Doctors can use patients’ consultation time to explain the harms of smoking and the possible benefits of quitting. Seek professional help The process of smoking cessation may be painful or repetitive, if necessary, they should take the initiative to seek the help of professional psychologists or clinicians, and progressively under the advice of doctors; doctors should take the initiative to understand the knowledge related to tobacco addiction, and based on the relevant knowledge, and actively promote the role of some practical psycho-behavioral therapies in cessation of smoking. In the process of smoking cessation, especially for those patients who are poisoned by smoking, it is not necessary to quit all at once, but try to make a practical plan to gradually reduce the amount of smoking until all quit; V. Drugs to assist Seek medical advice if necessary, use some drugs to assist smoking cessation and get through the physiological extreme period, assisting in cessation of smoking drugs, including preparations related to nicotine replacement therapy, bupropion and varenicline, and it is necessary to pay attention to the fact that, when using these drugs, the doctor must pay attention to these drugs. It is important to note that when using these medications, doctors must pay attention to the adverse effects and contraindications of these medications, and must inform patients in detail about the use of different types and dosage forms of medications, so as not to lose sight of one or the other. Finally, smoking cessation is not only a matter for doctors and smokers themselves, but also requires the participation and help of smokers’ family members, friends, and even the whole society. Even if you succeed in quitting for a short period of time, you should not take it lightly, as the possibility of relapsing to smoking still exists, so it is very important to strengthen the follow up for those who have succeeded in quitting smoking for the first time.
