Sometimes I feel a little discomfort on the left side of my chest when I get angry, excited or really stressed and nervous. To be exact its the upper left right.   Im a 42 year old male and I was diagnosed with a slightly enlarged heart about 6 months ago.  My cardiologist did a stress test and said its nothing to be worried about.  My cholesterol is a litle high so now I;m taking simvastatin.  Im physiclly active-I work out with weights, swim ,spin class 3 times a week and watch what I eat.
Hi threats good to know that you are following a good lifestyle but getting angry and taking a lot of stress is not for our body as a lot of hormonal and substantial changes happen when we are angry and stressed. I suggest you start doing meditation in the morning for about half an hour in fresh open air and try to avoid getting angry, try my advice you be surely be benefitted. Rest continue your cardiac meds as advised by your cardiologist. Good Luck
