Prevention of myocardial infarction.

Despite the rapid advances that have been made in the treatment of coronary artery disease, myocardial infarction remains the major cause of death in the developed world and a growing problem for developing countries. To address this growing problem, a strategy aimed at prevention of events in high-risk individuals is required. This involves assessment of cardiovascular risk followed by risk reduction. At present there is no perfect technique available for risk prediction, although computed tomography and magnetic resonance imaging scanning, along with serum markers of inflammation, offer the greatest potential. The applicability of these techniques at present is also limited by cost and accessibility. Risk reduction is possible through lifestyle changes and drug therapy, and effective risk assessment is essential in selecting those most likely to benefit from these interventions.
