If you have heart disease, it is often related to obesity, and the best way to treat it and reduce your risks and problems is to lose weight by eating more fruits and vegetables, which are also rich in things that will promote heart health and otherwise lower cholesterol and blood pressure.  This being said, there are other ways that some have found to reduce the risk factors to their heart. 

For one thing, many have found that meditation works quite effectively as does yoga.  These will reduce stress and promote relaxation, promoting a greater sense of calm and wellbeing.  In addition, yoga can lower the risk of stroke and kidney disease in many individuals.  Also, aerobic exercise gets the heart going in general, and it has been known to lower the problems associated with the heart as a whole. 

Putting just 30 minutes into any day or more for that matter will really help you to reduce your heart problems and otherwise help you.  Finally, of course I cannot stress enough the use of a healthy diet that includes more fruits and vegetables.  A low carb diet will only make your heart problems worse.  So I would definitely suggest a combination of all these steps to promote weight loss and a healthier heart as a whole.
