Heart disease is the leading cause of death in America, yet many people remain unaware of its risks until it’s too late. According to the Centers for Disease Control and Prevention (CDC), heart disease claims more lives than cancer, accidents, and even COVID-19. A 2025 report by the American Heart Association highlights that someone dies from cardiovascular disease every 34 seconds. With this in mind, when was the last time you had your heart checked?
February is American Heart Month—a timely reminder to prioritise your heart health. Scheduling an annual check-up could help you detect potential issues early and make lifestyle changes to prevent heart disease. Here’s everything you need to know about this silent killer, including when and why you should get screened.
What Is Heart Disease?
Heart disease is an umbrella term for various conditions that affect the heart, including:
Arrhythmias – Irregular heartbeats that can cause palpitations or dizziness.
Valve disease – When heart valves fail to function properly, affecting blood flow.
Congenital heart defects – Heart abnormalities present at birth.
Coronary artery disease (CAD) – The most common type, caused by narrowed or blocked arteries, increasing the risk of a heart attack.
Many people don’t realise they have heart disease until they experience symptoms of a heart attack or heart failure. That’s why regular screenings are essential for early detection and prevention.
Causes of Heart Disease
Heart disease can develop at any stage of life. While some forms, like congenital heart disease, are present from birth, others develop over time due to factors such as:
Genetics – A family history of heart disease increases your risk.
High blood pressure – Puts extra strain on the heart and arteries.
High cholesterol – Leads to plaque buildup, narrowing arteries.
Smoking – Damages blood vessels and reduces oxygen supply to the heart.
The CDC reports that nearly half of Americans have at least one risk factor for heart disease. Early screenings can help identify these risks before symptoms appear.
When Should You Get Screened for Heart Disease?
The American Heart Association recommends starting routine heart screenings at age 20. This may seem early, but establishing a health baseline helps monitor changes over time. Even if you are not at high risk, regular tests can provide valuable insights into your heart health.
Recommended Screening Schedule:
Blood Pressure – If below 120/80 mm Hg, check annually. If higher, test more frequently.
Cholesterol – Low-risk adults should test every four to six years; high-risk individuals may need more frequent testing.
Blood Glucose – Start testing every three years from age 45.
Lifestyle Factors – Every doctor’s visit should include discussions about diet, exercise, and smoking habits.
More Frequent Screenings for High-Risk Individuals
If you have high blood pressure, high cholesterol, a family history of heart disease, or lead a sedentary lifestyle, your doctor may recommend additional tests, including:
Electrocardiogram (ECG/EKG) – Measures heart rhythm and electrical activity.
Echocardiogram – Uses ultrasound to assess heart structure and function.
Stress Tests – Monitors heart performance during physical exertion.
Cardiac CT Angiography – Produces 3D images to detect artery blockages.
Peripheral Angiography – Identifies blockages in blood vessels outside the heart.
Practical Tips to Prevent Heart Disease
Heart disease is a serious condition, but the good news is that it’s largely preventable. Incorporating the following habits into your daily routine can significantly lower your risk:
✅ Quit Smoking – One of the biggest contributors to heart disease. Quitting reduces risk dramatically. ✅ Stay Active – Aim for at least 150 minutes of moderate exercise per week—just 30 minutes a day, five days a week. ✅ Monitor Your Health at Home – Use at-home blood pressure monitors, glucose testers, and fitness trackers to stay informed. ✅ Improve Your Diet – Reduce intake of saturated and trans fats, and focus on nutrient-rich foods like vegetables, whole grains, and lean proteins.
The Bottom Line
Your heart is one of your body’s most vital organs, and keeping it healthy requires regular care and attention. High blood pressure and high cholesterol are common conditions that increase the risk of heart disease, but routine screenings and lifestyle changes can make a significant difference.
Don’t wait for symptoms to appear—take a proactive approach to your heart health today. Regular check-ups with your doctor, combined with a heart-healthy lifestyle, can help prevent heart disease and ensure a longer, healthier life.
