Heart disease remains the world’s biggest killer disease. With 17.7 million deaths each year being a direct result of this disease, it accounts for one-third of all deaths in the world on an annual basis.

Fortunately, while heart disease is responsible for so many deaths, there are many simple steps people can take to prevent contracting the disease. Heart disease is often triggered by various poor lifestyle choices – choices which can have a direct impact on your heart’s health. Here are some of the biggest causes of heart disease.


A cause of heart disease and so many other illnesses besides, there aren’t many positive things to be said for smoking. There is a lot of emphasis on the damage smoking does to your lungs; while this shouldn’t be ignored, your heart does not escape the clutches of this deadly smoke stick.

Lack of exercise

Not taking a sufficient amount of exercise can have a profoundly detrimental effect on your health. If you spend all day sitting down; whether this is at a desk, in your car or just on the couch, you aren’t getting the blood pumping to your heart. A lack of exercise can lead to obesity, which is directly linked to heart disease. It’s amazing how much difference even taking a 20-minute walk each day can make to your wellbeing.


Although a lack of blood flow to the heart is a bad thing, too much can be a problem, too. Stress is a major cause of heart disease as it leads to an increased heart rate. This can leave the heart feeling weary and overworked.

Poor diet

Ever heard the expression ‘you get out what you put in’? This is certainly true in the case of your heart. Eating a poor diet is another cause of heart disease. It is vital that you eat a balanced diet which includes plenty of fresh fruit and vegetables to maintain a healthy heart. Living a life with a diet that consists completely of fatty foods and food with a high salt content is a surefire way of developing heart disease. These foods lead to high cholesterol levels in your blood, which can cause you to become overweight and have high blood pressure.


Consuming too much alcohol is another cause of heart disease. Alcohol in moderation won’t do you much harm, but drinking too much won’t just impact your liver, skin, teeth and brain, it will increase your chances of heart disease, too.
