Hello,
Your symptoms don't suggest any heart blockages, but you certainly have a risk factors like
cholesterol and
high bp. Also you mentioned there is enlargement of heart. So considering your echo report to be significant ( or it may be just a hypertensive change on echo which your doctor conveyed as enlargement, so please upload your report for better clarification) you should either undergo
stress thallium or TMT test which will further help to resolve the issue. I also think you should take treatment for cholesterol like
Atorvastatin, as these meds have multiple heart protective effect other than cholesterol lowering.
You should have a healthy lifestyle like avoiding fatty, oily and high calorie diet. Have low salt diet and monitor blood pressure regularly thrice a day for one week then once or twice a week. Regular exercises like brisk walking, jogging according your capacity at least 30 min a day and 5 days a week. Eat lots of green leafy vegetables, fruits, fish once or twice a week, avoid meat. Avoid
smoking and alcohol if any. There shouldn't be abdominal fat deposition or obesity.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Sagar Makode
