Smoking can induce coronary heart disease, arrhythmia and other heart diseases.
1. Harmful substances in tobacco will cause damage to the endothelium of blood vessels, resulting in coronary atherosclerosis, gradual narrowing of blood vessels, and will stimulate the sympathetic nerves of the human body, so that people’s heart rate accelerates, blood pressure rises, and myocardial oxygen consumption increases, and at the same time, it will cause platelet viscosity to increase, so that coronary vascular blood flow is slowed down, resulting in the formation of blood clots.
2. As the blood supply to the local myocardium is reduced due to narrowing of blood vessels, it can lead to myocardial ischemia, angina pectoris and even myocardial infarction and other diseases.
3. In addition, due to coronary artery stenosis, myocardial ischemia, as well as the continuous influence of harmful substances in tobacco on the cardiac conduction system caused by long-term smoking, it can also lead to the occurrence of cardiac arrhythmia such as atrial fibrillation, ventricular fibrillation, and so on.
The risk of cardiovascular disease is higher in smokers than in the general population, so it is recommended to smoke less or not to smoke, especially for those who suffer from basic cardiovascular diseases, it is recommended to quit smoking.
