We’re used to seeing headlines about what will or won’t increase your risk of having a heart disease. Some headlines can’t be trusted, but we know that with lifestyle changes and medication you can help reduce your risk of a heart event – even if you’ve had one already.

Our team has done our research and come up with five things we do or habits that most of us have and things we are exposed to that can increase the risk of having a heart disease.


1. SMOKING: This is the most popular habit that increases the risk of anyone having a heart disease. Hence the popular phrase “Smoking Kills”. If you smoke, you are more than two to four times more likely to have a heart attack, and you’re much more likely to die if you do have a heart attack.


2. Excess Weight: People who have excess body fat especially at the waist and belly are more likely to develop heart disease and stroke even if they have no other risk factors. Losing extra weight is good for your heart. It can also help you lower high blood pressure and manage diabetes. Carrying extra pounds, especially around the belly, strains the heart and tips you toward diabetes.


3. Gender: Most people don’t know this but Men have a greater risk of heart attack than women do, and they have attacks earlier in life. Even after menopause, when women's death rate from heart disease increases, it's not as great as men's.


4. Cholesterol: Cholesterol is a fatty substance found in the blood. Too much ‘bad’ cholesterol can increase your risk of developing a heart disease. It can cause atheroma to build up inside artery walls, preventing enough blood reaching the heart. If a piece of atheroma breaks off, a blood clot can form, blocking blood supply to the heart and the brain.


5. Lack of Exercise: People who don't exercise are more likely to get heart disease, and die from it, than people who do. Check with your doctor before starting a new exercise program, especially if you aren't active now. He/She can tell you what you can do.
