Heart disease is one of the leading causes of death globally, and every year, around two million people undergo open-heart surgery, according to the Cleveland Clinic. The Centers for Disease Control and Prevention (CDC) estimates that one in every four deaths each year is due to heart disease. Despite the advancements in medical technology, understanding the factors that increase the risk of heart problems remains crucial.
Dr. Jeremy London, a well-known heart surgeon, recently shared insights on his TikTok channel about the four common traits he has observed in his heart surgery patients. These traits, according to Dr. London, significantly raise the risk of heart disease. Here’s a closer look at the risk factors that could indicate a higher chance of heart issues.
1. Smoking: The Single Worst Thing for Your Heart
Smoking tops the list of risk factors for heart disease, and it’s no surprise why. Dr. London emphasizes that smoking is the “single worst thing you can do for your cardiovascular health.” It is one of the most common traits among his heart surgery patients. Smoking doesn’t just impact your lungs; it damages your heart and circulatory system too.
How Smoking Impacts Your Heart Health
According to Action on Smoking and Health (ASH), about one in every eight people in the UK smokes. Smoking contributes to fatty deposits building up in the coronary arteries, leading to reduced blood flow to the heart. This not only increases the risk of heart attacks but also raises the likelihood of developing broader heart and circulatory diseases.
The British Heart Foundation reports that smoking can also trigger high blood pressure, irregular heartbeats, and arterial damage, further stressing the heart. If there’s one change to make for a healthier heart, quitting smoking could be the most impactful decision.
2. Obesity: A Major Driver of Heart Disease
The second trait Dr. London identifies among his heart surgery patients is obesity. Obesity isn’t just about weight—it’s about the strain it places on the body, particularly the heart. Dr. London explains that excessive fat stores, especially abdominal fat, drive inflammation and increase cardiovascular risk.
Why Obesity Is Dangerous for Your Heart
Penn Medicine states that obesity can lead to increased levels of bad cholesterol and triglycerides while decreasing good high-density lipoprotein (HDL) cholesterol. HDL helps remove bad cholesterol from the bloodstream, thereby lowering the risk of heart disease. Additionally, excess weight requires more oxygen and nutrients, which can raise blood pressure as the heart works harder to pump blood throughout the body.
The correlation between obesity and heart disease is clear: maintaining a healthy weight can significantly reduce the risk of heart attacks and other cardiovascular issues. For those struggling with obesity, adopting a balanced diet and regular exercise can be transformative steps toward better heart health.
3. Diabetes: Managing Glucose for Heart Health
Diabetes is the third common trait that Dr. London observes in heart surgery patients. The inability to properly manage glucose levels is a strong indicator of overall metabolic health, which directly impacts cardiovascular risk. Whether it’s Type 1 or Type 2 diabetes, the condition complicates heart health by affecting the body’s ability to control blood sugar levels.
The Connection Between Diabetes and Heart Disease
According to Diabetes UK, around 4.4 million people in the UK are living with diabetes, with an additional 1.2 million likely undiagnosed. Poorly managed diabetes can lead to heart disease, as high blood sugar levels damage blood vessels and the nerves that control the heart.
Dr. London suggests that adopting a whole foods diet, limiting processed foods, and incorporating regular exercise can help manage blood sugar levels. Simple steps, such as taking a 15-minute walk after meals or adding resistance training to your routine, can have a significant impact on reducing cardiovascular risks associated with diabetes.
4. Family History: The Unavoidable Risk Factor

The final trait Dr. London highlights is family history. While you can control lifestyle factors like smoking and diet, you can’t change your genes. A family history of heart disease is a significant risk factor that can’t be ignored. Knowing your genetic predisposition can help you take proactive measures to reduce other risk factors.
Understanding Your Family’s Health Background
The Missouri Department of Health and Senior Services notes that family history is one of the most important indicators of potential health risks, including heart disease, high blood pressure, and diabetes. Dr. London emphasizes that while we can’t run from our genes, we can make lifestyle choices that influence how those genes are expressed.
He encourages individuals to gather detailed information from first-degree relatives like parents and siblings. Expanding this inquiry to second-degree relatives such as aunts, uncles, and grandparents, and even third-degree relatives like cousins, can provide a more comprehensive picture of potential risks.
Proactive Steps for Better Heart Health
Now that you know the four traits that could raise your risk of heart disease, what can you do to protect yourself? Dr. London offers several practical recommendations:
1. Quit Smoking for Good
If you’re a smoker, quitting is the best thing you can do for your heart. It may not be easy, but with support groups, nicotine replacement therapies, and professional help, it is possible.
2. Maintain a Healthy Weight
Focus on a balanced diet that emphasizes whole foods, lean proteins, and plenty of vegetables. Combine this with regular exercise, whether it’s a daily walk, strength training, or a fun activity like dancing or swimming.
3. Manage Blood Sugar Levels
For those at risk of or currently managing diabetes, monitor your blood sugar regularly and maintain a diet low in processed sugars. Incorporating exercise after meals can also help keep blood sugar levels stable.
4. Know Your Family History
Understanding your genetic risk factors can help you take more targeted preventive measures. Talk to your family about their health history and discuss your findings with your healthcare provider to develop a personalized plan.
Conclusion: Taking Charge of Your Heart Health
Dr. London’s insights into the traits shared by heart surgery patients provide valuable information for anyone looking to reduce their risk of heart disease. While traits like family history can’t be changed, factors such as smoking, obesity, and diabetes can be managed through lifestyle adjustments.
Remember, heart disease doesn’t happen overnight—it develops over time due to a combination of genetic and lifestyle factors. By making healthier choices today, you can significantly lower your risk of heart issues in the future. So, why wait? Start making small, heart-healthy changes today and give yourself the best chance at a longer, healthier life.
