Many patients think that myocardial infarction is cured even if a stent is placed and the blood vessel is opened, and it will not recur, which is a very wrong perception.
The study found that 20% of patients who survive the first acute myocardial infarction will have a second cardiovascular event within the first year, and about half of the patients with severe coronary events are those who have had a previous myocardial infarction, and the disease of another myocardial infarction is more severe and the mortality rate is higher. It can be seen that for patients who have had a myocardial infarction, it is necessary to pay more attention to preventing the recurrence of myocardial infarction.
To prevent recurrence of myocardial infarction, it is important to quit smoking.
As you know, to prevent the first heart attack, we call it "primary prevention". In this prevention, the order of importance for risk factors is as follows: high blood pressure> smoking> high cholesterol > diabetes.
Preventing the recurrence of myocardial infarction is called "secondary prevention". So, are secondary prevention of myocardial infarction the same as primary prevention? A recent study published in the Journal of the American Heart Association gives us some insights. The study was conducted for 20 years in 880 patients with coronary artery disease who had myocardial infarction or coronary artery stenosis more than 70% before the age of 45, and found that more than one-third of these patients had a major coronary event, with recurrence of myocardial infarction being the most common. Studies have found that recurrent events are more closely related to persistent smoking, inflammatory diseases (such as hepatitis, polyarthritis, etc.), diabetes mellitus, and multivessel disease, among which persistent smoking has the greatest impact on prognosis.
It can be seen that smoking plays an important role in promoting the recurrence of myocardial infarction, so what is the effect of smoking cessation in preventing the recurrence of myocardial infarction? An earlier study, which pooled data from nearly 6,000 patients, found that smoking cessation reduced cardiovascular mortality by 50% and was the most effective secondary prevention strategy.
Quit smoking early and benefit more.
Previous studies have found that no matter how much you smoke or how long you smoke, all smokers can benefit from quitting.
In order to protect cardiovascular health and stay away from tobacco, we call on everyone to:
If you don't smoke, don't smoke a single cigarette, and avoid exposure to secondhand smoke!
If you are smoking, it is useless to reduce the amount of smoking, and complete withdrawal is the "king"!
Those who have quit smoking are at high risk of relapse, and it is equally important to maintain the results of the battle!
The benefits of quitting smoking are visible
If you quit smoking, there will be fewer coughs;
If you quit smoking, your breath is fresher;
If you quit smoking, your skin is fine;
If you quit smoking, you are more confident;
If you quit smoking, you can work more efficiently;
If you quit smoking, most importantly, you can save a lot of money!
