Cholesterol is an important heart-health marker, but it is not the only factor that determines your risk of a heart attack. Several other conditions and lifestyle habits can damage blood vessels, increase inflammation, or put extra strain on the heart.
1. High Blood Pressure
High blood pressure forces the heart to work harder and can gradually damage the walls of arteries. Over time, this damage can contribute to plaque buildup and increase the risk of heart attack and stroke.
What to do: Check your blood pressure regularly, reduce excess salt, stay physically active, maintain a healthy weight, and take prescribed medicines consistently.
2. Diabetes and High Blood Sugar
Persistently high blood sugar can damage blood vessels and nerves and is strongly linked with cardiovascular disease. People with diabetes may have a higher risk of developing plaque in their arteries.
What to do: Monitor blood glucose, follow a balanced diet, exercise regularly, and keep diabetes under medical control.
3. Smoking and Tobacco Use
Smoking damages the lining of blood vessels, promotes plaque formation and makes blood more likely to clot. Both cigarettes and other tobacco products can significantly increase cardiovascular risk.
What to do: Quitting tobacco is one of the most effective steps you can take to protect your heart.
4. Excess Weight and Physical Inactivity
Being overweight, particularly carrying excess abdominal fat, is associated with high blood pressure, diabetes, abnormal cholesterol levels and inflammation. Lack of physical activity can further increase these risks.
What to do: Aim for regular physical activity, such as brisk walking, along with a balanced diet and healthy weight management.
5. Stress, Poor Sleep and Unhealthy Lifestyle
Long-term stress and inadequate sleep can contribute to high blood pressure, unhealthy eating, weight gain and other cardiovascular risk factors. Excessive alcohol consumption and a diet high in processed foods, saturated fats and added sugars can also negatively affect heart health.
What to do: Prioritize 7–9 hours of sleep for most adults, manage stress, eat a heart-healthy diet and stay physically active.
The Bottom Line
Heart attack prevention is about more than checking cholesterol. Keep track of your blood pressure, blood sugar, tobacco use, weight, physical activity, sleep and stress as well. Regular health checkups can help identify risk factors early and allow you to address them before they cause serious problems.
