8 Biggest (and Preventable) Risk Factors of Heart Disease

Heart disease, also known as cardiovascular disease, is an overarching term that encompasses several conditions affecting the heart and blood vessels. Despite its standing as the leading cause of death globally, a significant proportion of heart disease cases can be prevented by addressing risk factors. In this blog post, we dive into the five biggest—and importantly—preventable risk factors of heart disease.

1. Unhealthy Diet

An unhealthy diet is one of the primary risk factors for heart disease. A diet high in saturated fats, trans fats, and cholesterol can raise blood cholesterol levels, which can lead to atherosclerosis, a condition where plaque builds up in the arteries, potentially leading to heart attacks and strokes.

How to Prevent: Strive to incorporate a heart-healthy diet into your routine. This should include:

  • Plenty of fruits and vegetables
  • Whole grains
  • Lean proteins (like poultry and fish)
  • Low-fat or non-fat dairy products
  • Limiting saturated and trans fats, sodium, red meat, and sweets

2. Physical Inactivity

Physical inactivity is a silent killer and a significant contributor to heart disease. Lack of exercise leads to obesity, high blood pressure, high cholesterol, and diabetes—all of which increase the risk of developing heart disease.

How to Prevent: Regular physical activity can significantly reduce the risk of heart disease. Try to aim for at least 30 minutes of moderate-intensity exercise five times a week or 25 minutes of vigorous activity three times a week.

3. Tobacco Use

Whether it’s smoking or using smokeless tobacco, tobacco use is a significant risk factor for heart disease. It can damage the heart and blood vessels, leading to narrowing of the arteries (atherosclerosis) and heart attacks.

How to Prevent: If you smoke, the best step towards preventing heart disease is to quit. There are numerous resources available, including medication and counselling, that can support you on this journey.

4. Excessive Alcohol Use

While moderate alcohol use can potentially have some heart benefits, excessive drinking can lead to increased blood pressure, high levels of blood fats, and heart failure.

How to Prevent: Stick to the recommended limits of alcohol use. That’s generally up to one drink a day for women and up to two drinks a day for men.

5. Uncontrolled Stress and Anger

Prolonged stress and uncontrolled anger can contribute to heart disease. They can lead to high blood pressure and other potential damage to the body’s systems.

How to Prevent: Find healthy ways to cope with stress, such as exercise, meditation, or seeking professional help when needed. Keeping your anger in check can also be beneficial. Consider counselling or anger management classes if needed.

The Power of Prevention

A critical point to bear in mind is the power of prevention. Heart disease doesn’t develop overnight; it’s usually the result of a combination of factors that have built up over time. But that also means you have the power to reduce your risk by making lifestyle changes early.

6. High Blood Pressure

High blood pressure, also known as hypertension, is a significant risk factor for heart disease. It increases the heart’s workload, causing the heart to thicken and become stiffer. This stiffening of the heart muscle is not normal, and it causes the heart not to work properly, leading to heart disease.

How to Prevent: Regular check-ups can ensure that you are aware of your blood pressure levels. If they are consistently high, lifestyle changes or medication, under the guidance of a healthcare professional, can help manage your blood pressure.

7. High Cholesterol

Cholesterol is a type of fat produced by your liver and found in your blood. While your body needs some cholesterol to function, having too much can lead to a buildup in your arteries, increasing your risk of heart disease.

How to Prevent: Regular cholesterol checks, maintaining a healthy diet, regular physical activity, and avoiding tobacco smoke are the best ways to maintain healthy cholesterol levels. Your doctor might also prescribe cholesterol-lowering medications, if necessary.

8. Obesity

Obesity, particularly when the weight is carried around the abdomen, is a significant risk factor for heart disease. It’s closely linked with other risk factors such as high cholesterol, high blood pressure, and diabetes.

How to Prevent: Maintaining a healthy body weight through a balanced diet and regular physical activity is key. If you’re struggling with weight loss, consider reaching out to a healthcare professional for guidance and support.


In conclusion, heart disease is a serious health threat that claims millions of lives every year. However, it’s crucial to remember that many of the risk factors associated with heart disease can be effectively managed through lifestyle changes and preventative measures. By paying attention to these five areas—diet, physical activity, tobacco use, alcohol intake, and stress management—you can significantly lower your risk and ensure a healthier, longer life.
