The Australian National University research has found that smoking increases the risk of all cardiovascular diseases by at least a factor of two. Quitting smoking before the age of 45 can reduce the risk by 90%.
The team tracked about 190,000 smokers and non-smokers over the age of 45 and investigated the effects of smoking on 36 cardiovascular diseases.
During an average follow-up of 7.2 years, 27,511 fatal and non-fatal major cardiovascular events occurred, including 4548 (3.2) acute myocardial infarction, 3991 (2.8) cerebrovascular disease, 3874 (2.7) heart failure, and 2311 Example (1.6) Peripheral arterial disease events.
At baseline, 8% were current smokers and 34% were former smokers.
Among the 36 most common cardiovascular disease subtypes, the incidence of 29 diseases is significantly increased among current smokers.
Compared with people who have never smoked, the risk of death from cardiovascular disease is about doubled, the risk of any major cardiovascular disease is increased by 63%, the risk of acute myocardial infarction is increased by 1.5 times, and the risk of cerebrovascular disease is increased by 1.16. Times, the risk of heart failure increased by 1.23 times, the risk of peripheral cardiovascular disease increased by 4 times, the risk of atrial fibrillation/flood increased by 30%, the risk of pulmonary embolism increased by 41%, and the risk of myocardial infarction increased by 1.8 times.
Paroxysmal tachycardia is a newly discovered hazard from smoking, and smoking increases its risk by 50%.
The research also found that people who smoked an average of five cigarettes a day had twice the risk of dying from cardiovascular disease. The more smoking, the more obvious the risk increase.
More than one-third of cardiovascular deaths and one-quarter of acute coronary syndrome hospitalizations in patients over the age of 65 can be attributed to smoking.
The good news is that research shows that smoking cessation can significantly reduce the risk of heart attack, stroke, and death from cardiovascular disease compared to continuing smoking.
And smoking cessation at any age can bring health benefits, especially if you quit smoking before the age of 45 to avoid about 90% of your cardiovascular risk.
