Hi welcome to healthcare magic,
I understand your query and concern.
Your symptoms are suggestive of
heart failure secondary to ischemic changes in the heart.I advise you to get an ECG,2 D Echo,
lipid profile,hsCRP immediately to confirm the diagnosis.Monitor your blood pressure regularly.Take fluids 3-4 litres per day.If blood pressure is less than 80/60 mm hg you may need intravenous fluids.Drugs like
clopilet,
ecosprin,atorvas ,inotropes like digoxin will be helpful.Coronary angiogram with or without stenting will be the procedure of choice.
Consult your cardiologist for expert management.
Hope I have answered your query at the moment,
Post your further queries if any,
Thank you
