Hello zaffar and thanks fro the query It is very common with heart patient that they feel discomfort after meals. Try to avoid overeating and take a little walk after every meals. Do not lie down after meals. Aspirin also cause gastric problem so you can shift to other anti-coagulants like Clopidogrel which has no or very less gastric side effects. As per palpitations is concern their are many options available to alter your medication. As you have MVP recurrent palpitations can be dangerous. You can take other type of betablockers like metoprolol ans calcium channel blockers like Dilzem to control your palpitations. Avoid stress as much as you can. Please consult your doctor before altering your medications. Best Wishes
