Hi, i do care for your concern. Your present medication is anti platelet aggregator, which help in prevention of clot formation, which is more common in atrial fibrillation. This is the third time you are suffering from attack, hence i would advise you to be more cautious in preventing from further attack. need not panic or stress yourself as this would add to the worry, be healthy, follow the diet and medications strictly, as this will add to the help. strict diet, with low fat and high nutritive food should be taken. doing some meditation would help to some extent. Hope I have answered your question. If you have any further questions I will be happy to help.
