Michael Washington:
Dr. Smith, you’ve spent your career studying cardiovascular disease. Why is heart health such a pressing concern today?
Dr. Sidney C. Smith, Jr.:
Heart disease is now the leading cause of death globally. It’s truly an epidemic — but it’s an epidemic that need not happen. The good news is that most of these diseases are preventable through healthy lifestyle choices.
We’re here in Carmichael Gym because physical activity is one of the best things you can do for your health. Leading an active life is crucial for preventing cardiovascular disease.
When I talk with patients about exercise, I tell them: do it daily. If you make a commitment to exercise with another person, you’re far more likely to stick with it — because you’re not just committing to exercise, you’re also committing to a friend. Whether it’s biking, walking, playing basketball, or tennis — whatever form it takes, it should be part of your everyday life.
Michael Washington:
So regular activity is the foundation. What else do you emphasize for long-term heart health?
Dr. Smith:
Right alongside physical activity, the next big one is don’t use tobacco. Smoking is probably the worst thing you can do for your health. And we have to remember that secondhand smoke is also dangerous.
Number three is a good diet. Eat the right foods — a balanced diet rich in fruits, vegetables, and fish. Lean meats are fine, but avoid saturated fats and trans fats. Combine that healthy diet with regular exercise, and you’ve already made tremendous progress toward heart health.
Michael Washington:
And beyond lifestyle, what key metrics should people be monitoring?
Dr. Smith:
Know your blood pressure. High blood pressure, along with smoking, is one of the top two risk factors for heart disease. It’s also a leading cause of stroke — and here in the southeastern United States, we live in what’s called the “stroke belt.” So check your blood pressure and manage it early.
Next, understand your cholesterol levels — your blood lipids matter. And finally, make sure you’re screened for diabetes. These are all pieces of the same puzzle.
If we can make these lifestyle changes and stay on top of our health, we can truly prevent most heart disease. And honestly, as a cardiologist, one of my greatest joys would be to put myself out of business — because that would mean people are healthy and heart disease is no longer taking lives unnecessarily.
