The condition that you are facing right now is called cardiomegaly. This is the medical term for the condition you have described as an enlarged heart. The problem is caused by a wide variety of reasons. Fundamentally, all these causes lie in something that causes the heart to have to beat more and thereby build up muscle mass causing the increased size. In some cases, this is also a congenital heart defect that just happens. In some cases the condition has no symptoms and a person could carry on with a case of cardiomegaly with no problems at all. To answer your question on whether there is a specific exercise for reducing the size of the heart, this would be incorrect. Treating this condition requires one to treat the underlying condition and reducing the need for the heart to pump vigorously. To this effect, you might just have work out and do minute cardiovascular exercise to lose weight. However beyond this, there is no specific exercise that you can indulge in. At this point, it is probably worth noting that there are some breathing and relaxing exercises that are a part of yoga. These exercises are known to reduce overall body metabolism and thereby the load on the heart to beat. If you are willing to indulge in this school of thought, then you should visit your local yoga center or search the internet for an instructor who knows of this exercise.
Cardiomegaly is a condition that usually follows most heart conditions and will eventually cause a heart attack if not treated. The treatment itself relies heavily on the root cause of the cardiac problem itself. hypertension is one of the most common reasons for heart disease and will cause the heart to build up muscle mass to pump better. The treatment for this is therefore the use of anti-hypertensives like Angiotensin Converting Enzyme or ACE inhibitors, Angiotensin Blockers, beta blockers, and other medication that reduce the amount of sodium in the body. These may also be combined with the use of diuretics. Natural herbs that reduce hypertension are garlic, ginger and feverfew to name a few.
Most doctors will also prescribe a regime of diet change to one that is vegetarian, reducing body mass, and a complete eight hours of rest. Treatment may eventually involve excising some of the enlarged heart tissue and in some cases even a heart transplant.
