As we all know, smoking is a kind of behavior that is extremely harmful to physical health, and Dr. Zhang often advises friends to quit smoking, but many friends cannot get rid of their addiction, so that they finally regret the stage of heart attack and cerebral infarction. So faced with the question "Why does smoking cause blood vessel blockage and blood pressure to rise?" As a cardiologist, Dr. Zhang needs to say more for everyone. #谣零零计划 #
Our country's latest lifestyle guidelines point out that smoking is the second risk factor for the burden of disease in mainland China, and the death toll due to smoking in mainland China reached 2.49 million in 2017. Smoking rates are now 52.1% for men and 2.7% for women. It can be seen that the smokers are mainly male. In addition, about 740 million people on the mainland are exposed to secondhand smoke, including about 180 million children. Almost all a large number of epidemiological studies at home and abroad have invariably shown that whether it is active smoking or passive inhalation of second-hand smoke, it will cause an increased risk of the incidence and death of serious cardiovascular diseases such as coronary heart disease, stroke, and heart failure.
In fact, some patients who have suffered myocardial infarction and cerebral infarction have the habit of smoking, at this point, many ordinary people have feelings, and everyone looks back at those around them who have myocardial infarction and cerebral infarction at a young age, is it a smoker? I believe that many people also agree with this statement. In other words, the unhealthy behavior of smoking is indeed one of the important reasons for people to have cardiovascular and cerebrovascular blockages.
On the surface, smoking is more associated with lung diseases, but a behavioral habit that is not closely related to cardiovascular and cerebrovascular diseases can lead to blood vessel blockage? In fact, this is why everyone does not understand the harm of smoking. The reason why smoking blocks blood vessels, there are many mechanisms involved, such as smoking will cause damage to vascular endothelial cells and then allow scurvy lipid accumulation, while smoking will also activate the inflammatory response of the whole body, and smoking will also cause platelet aggregation, and so on. In short, smoking triggers many mechanisms and causes a variety of adverse consequences, the most serious of which is the result of blocking blood vessels in the human body.
In fact, smoking patients are also prone to blood pressure rise and fluctuation, which has many reasons, such as activating the sympathetic nervous system, activating the renin-angiotensin-aldosterone system, causing sodium water retention and vasoconstriction and so on. If patients with hypertension quit smoking, it will be very helpful to reduce blood pressure and reduce the occurrence of cardiovascular and cerebrovascular diseases. This is felt by many hypertensive patients who have successfully quit smoking.
Smoking is one of the important risk factors for cardiovascular disease and tumor cancer. And for many friends, smoking cessation is very important, while eliminating "second-hand smoke" is also very important, reducing the chance of passive smoking can also reduce the occurrence of cardiovascular disease, hypertension and tumor cancer. Therefore, it is advised that friends with smoking habits must quit smoking as soon as possible, and some teenage friends should not learn to smoke. Stay away from tobacco, you are close to health. I hope dr. Zhang's popular science can help you.
