Effects of Smoking on Heart Health: Using tobacco products may affect your heart health and may increase your risk of having a heart attack or developing other health conditions such as blood clots. Taking the time to learn about the dangers of smoking can help you to make a more informed decision about your heart health.
Nicotine
Several studies have been conducted to evaluate the effects of nicotine on the heart. These studies suggest that nicotine may have atherogenic effects on the cardiovascular system.
Nicotine is a chemical in cigarettes that binds to nicotinic cholinergic receptors, located in the brain, autonomic ganglia, and neuromuscular junction. Nicotine causes an increase in blood pressure and myocardial work, as well as an increase in heart rate and blood coagulability. It may also be a contributor to acute vascular events such as myocardial infarction, stroke, or arrhythmia.
The effects of nicotine on the cardiovascular system may be more intense when the delivery of cigarette smoke occurs rapidly. Transdermal nicotine is a delivery method that has less effect on myocardial work, but appears to have less effect on coronary vascular resistance.
Nicotine can also increase myocardial contractility. However, these effects appear to be due to the sympathetic nervous system and not the heart itself.
The effects of nicotine on heart health have also been studied in animals. In monkeys, nicotine increased plasma levels of LDL. Similarly, nicotine injection into rabbits increased total cholesterol.
Carbon monoxide
Using tobacco increases the risk of developing cardiovascular diseases, such as strokes, high blood pressure, blood clots, and atherosclerosis. Studies have shown that exposure to environmental carbon monoxide is associated with increased cardiovascular morbidity and mortality.
Carbon monoxide is found in many sources of combustion. These include fires, motor vehicle exhaust, and gas stoves. Carbon monoxide is an odourless, colorless, poisonous gas. It binds with hemoglobin in the blood. The binding disrupts the delivery of oxygen to the body’s tissues. The result is hypoxia. This causes the organs to become stressed and suffer damage.
In the study, the carbon monoxide concentration was compared in smokers and non-smokers. In smokers, the average carbon monoxide level was approximately 1.9 ppm, while the level in non-smokers was approximately 1.2 ppm. However, smokers with a carbon monoxide concentration above 13 ppm had a significantly increased risk of major adverse events.
In the same study, carbon monoxide was administered inhalationally under conditions similar to cigarette smoking. The inhaled CO had a negative inotropic effect on the myocardium, which was due to an increase in heart rate and afterload. The negative inotropic effect on the myocardium was also due to an increase in carboxyhemoglobin level.
Blood clots
Whether it is secondhand smoke, or the chemical constituents of cigarettes, smoking damages the blood vessels and can cause a host of health complications. It increases the risk of heart disease and stroke and contributes to peripheral vascular disease. Smoking also increases the risk of lung disease. It also reduces HDL (good) cholesterol.
The chemical compounds in cigarette smoke can irritate the walls of blood vessels, which can result in inflammation, thickening of the blood, and clotting. These chemicals are especially harmful to the heart and brain. They can also cause damage to the mouth, cervix, and throat.
Smoking also increases blood pressure, which increases the risk of coronary heart disease. It can also cause atherosclerosis, a buildup of plaque in the arteries, which is comprised of calcium and fat. When plaque clogs arteries, the heart can’t pump blood properly and blood flow is disrupted.
A new study has shown that smoking is linked to a reduction in the function of the heart. The study involved comparing echocardiography measures of current smokers versus never smokers.
Abdominal aortic aneurysm
Approximately 200,000 people are diagnosed with abdominal aortic aneurysm each year, making it the third most common blood vessel problem in the United States. Most are discovered before they burst and are treated by imaging tests such as CT scans and ultrasound.
The most common risk factor for abdominal aortic aneurysms is smoking. Using tobacco can damage the artery wall, making it weaker. The risk of developing an abdominal aortic aneurysm increases by up to four times for smokers than non-smokers. It is important to stop smoking to prevent aneurysms.
Other risk factors include high cholesterol and high blood pressure. Men over the age of 60 are more likely to have aneurysms than women. In addition, genetic diseases can cause blood vessel weakness.
Lifestyle changes can help reduce the risk of aneurysms, including maintaining a healthy weight and avoiding alcohol and smoking. Keeping your blood pressure under control can also reduce your risk of aneurysms.
A large abdominal aortic aneurysm can cause internal bleeding and other complications. Surgery is sometimes necessary to remove a large aortic aneurysm. However, many AAAs are small and can be monitored with regular ultrasounds. In conclusion, e-cigarettes are not as dangerous as traditional cigarettes and only contain nicotine. The available facts indicate that e-cigarettes emit fewer numbers of toxins than tobacco cigarettes.
Moreover, the e-cigarettes can be used as a quit-smoking tool since they have higher nicotine content than nicotine replacement medications. Lastly, e-cigarettes can be used to reduce health care costs since they cost much less than the standard treatment methods.
