Studies have shown that smoking has a great impact on blood pressure. Smoking can lead to hypertension. After smoking a cigarette, the heart rate increases by 5 to 20 times per minute, and the systolic blood pressure increases by 10 to 25 mmHg.
In untreated patients with hypertension, the 24-hour systolic and diastolic blood pressure of smokers are higher than that of non-smokers, especially the nighttime blood pressure is significantly higher than that of non-smokers, and the nighttime blood pressure rise is directly related to left ventricular hypertrophy, that is to say, smoking will cause an increase in blood pressure and have adverse effects on the heart.
Because tobacco and tea contain nicotine, also known as nicotine, which can excite the central nerve and sympathetic nerve to accelerate the heart rate. At the same time, it also urges the adrenal gland to release a large amount of catecholamines, which makes the arterioles contract, leading to an increase in blood pressure. Nicotine can also stimulate the chemical receptors in the blood vessels and reflexively cause an increase in blood pressure.
If people with hypertension continue to smoke, it will do great harm. Because smoking can directly cause vascular damage, these have been clearly confirmed in clinical studies. Smoking will cause arterial intima due to nicotine, tar and other harmful components in tobacco, that is, there will be damage in the arterial intima. With the damage of arterial intima, atherosclerotic plaque will be formed. After continuous formation of diffuse lesions, it will affect the contraction and relaxation of normal blood vessels. If the patient suffers from hypertension and has the habit of smoking, it will accelerate the progress of atherosclerosis.
Smoking and hypertension are both important risk factors for cardiovascular and cerebrovascular diseases. Once atherosclerotic plaque progresses, vascular stenosis will be very obvious, resulting in insufficient blood supply to corresponding organs. The greatest harm is atherosclerotic plaque, which may lead to the collapse of unstable plaque, resulting in acute thrombotic events, such as cerebral infarction and myocardial infarction. Smoking will also have an impact on hypertension, because it will affect the relaxation and contraction of blood vessels, making it difficult to control blood pressure, and even a sharp rise in blood pressure. Therefore, it is suggested that patients with hypertension and smoking should try to quit smoking.
The World Health Organization has decided to designate May 31 of each year as the world No Tobacco Day, and China also regards this day as China's no tobacco day. The no smoking day aims to remind the world that smoking is harmful to health, call on smokers all over the world to give up smoking, and call on all tobacco producers, sellers and the entire international community to join in the anti smoking campaign to create a tobacco free environment for mankind.
Meanwhile, we should pay more attention to the monitoring of blood pressure in our daily life. Now many household medical devices with simple design and easy use are gradually entering thousands of households. A household digital blood pressure monitor will be a better choice for you to take care of your health.
