There are a number of things that can contribute to negative cardiovascular function. Reducing your alcohol intake and quitting smoking are two things you can do that will have an almost immediate positive affect on your heart health. You should also work with your doctor to address other chronic health problems such as hypertension, high cholesterol, and diabetes, as all of these can be major contributing factors to cardiac conditions. If you have been diagnosed with more than one of these conditions, it can exponentially increase your risk for developing a heart condition. Excess body fat, eating an unbalanced diet that is high in certain types of fats, and excessive stress can also contribute to your cardiac disease risk.
