Is is safe for everybody in the country to take a baby aspirin daily to help prevent a heart attack?

No: Every study that has examined this question has shown that among large populations exposed to small doses of aspirin, there is an increase in peptic ulceration, abnormal bleeding, and intracranial hemorrhage when compared to matched controls who received no aspirin. Only those at risk of heart attacks or clotting type strokes should take it. (men>50, women >60 if there's no contraindication).

NO: Routine use of any medication to the population at large can create newer problems that we are not anticipating before. Low dose Aspirin can prevent platelet aggregation and decrease the incidence of coronary thrombosis in high risk patients.People with diabetes mellitus, obesity , family history of heart disease or previous myocardial infarction are the prime people to benefit from Aspirin therapy.
