Abstract

Coronary artery disease (CAD) is a leading cause of death and disability in the elderly. Several recent studies have shown that silent myocardial ischaemia (SMI) is a common manifestation of CAD, especially in the elderly. As many as 40% of elderly patients with no prior history of CAD may have underlying asymptomatic disease and up to 50% of elderly patients with known CAD might have evidence of SMI. The results of studies in elderly patients with CAD have also shown that SMI might exist despite antianginal therapy that is considered adequate for symptom control. In order to diagnose such residual SMI, the clinician would need to perform 24- to 48-hour Holter monitoring in the ambulatory setting while the patient is performing routine daily activities. Although a number of anti-ischaemic drugs have been evaluated for the treatment of SMI, available data suggest that β-blocker given alone or in combination with a nitrate compound or calcium antagonist provides the best therapeutic choice. The long term benefit of SMI suppression in elderly patients has not been established. Future studies need to evaluate the clinical benefits of therapy given for SMI in the elderly.
