Final answer:
For an old or healed myocardial infarction not requiring further care, the recommended strategy is usually to continue medical therapy without intervention, including lifestyle changes and maintenance of current medication regime to manage cardiovascular risk factors.
Step-by-step explanation:
For an old or healed myocardial infarction (MI) that does not require further immediate care, the appropriate management strategy depends on the individual patient's condition. However, in many cases, continuing medical therapy without further intervention is the recommended management strategy. This involves making lifestyle changes such as adopting a diet low in sodium and saturated fats, engaging in regular exercise, smoking cessation, and possibly taking medications to lower cholesterol and blood pressure. It might also include the maintenance of existing treatments like beta-blockers or nitroglycerine.
Coronary angiography followed by percutaneous coronary intervention, coronary artery bypass graft surgery (CABG), or the administration of thrombolytic therapy are more likely to be considered in acute cases or when complications arise that require immediate attention. For a patient with stable cardiac function where the MI has healed, these more invasive procedures are generally not indicated unless symptoms recur or complications develop.
