Smoking not only affects lung health, but is a leading risk factor for coronary heart disease. We’ve been blogging recently about the dangers of smoking — urging those at risk to consider CT lung screening to make sure there are not lung problems.
But smoking has many other dangerous effects, and as we move into February “Heart Month” it’s wise to consider what smoking does to the vascular system. Smoking is known to lead to atherosclerosis — a disease in which a waxy substance called plaque builds up in the arteries, narrowing them and limiting the flow of oxygen-rich blood to the organs. Coronary heart disease occurs when the plaque builds up in the arteries and can lead to arrhythmias, heart disease, and heart failure.
According to the American Heart Association, the effects of smoking on heart health include:
- A decrease in HDL (“good”) cholesterol.
- Increases the chance of heart disease if it runs in the family.
- Increases the chance of blood clots.
- Higher risk of heart disease if smoking is resumed after heart bypass surgery.
- Creates higher incidences of peripheral arterial disease and aortic aneurysms.
In addition to lung damage caused by smoking, secondhand smoke can also harm the heart of blood vessels. Babies and children are especially at risk from secondhand smoke.
Quitting smoking (and avoiding secondhand smoke) is key to avoiding problems with both your heart and lungs. There are many other things you can do to improve your heart health, such as eating healthy, obtaining or maintaining a healthy weight, managing stress, and exercising.
In our next blog, we’ll tie together some things about smoking, heart disease, and imaging exams RMI provides to help you and your doctor determine your risk. Here’s a hint: during February, we offer more than a 20% savings on CT Calcium Scoring exams.
