Screening echocardiograms not beneficial

Clinical Question

Does screening for heart disease with echocardiography decrease mortality, myocardial infarction risk, or stroke risk?

Bottom Line

Population-based screening for heart disease or valve disease with echocardiography will identify cardiac pathology in patients but does not decrease mortality, myocardial infarction risk, or stroke risk. (LOE = 1b)

Study Design: Randomized controlled trial (non-blinded)
Funding: Unknown/not stated
Setting: Population-based
Allocation: Uncertain


In 1994 and 1995 Norwegian researchers enrolled 6861 middle-aged (average age = 60 years) inhabitants of a single city (Tromsø). The participants were randomly assigned, concealed allocation unknown, to a one-time screening for heart disease using 2-dimensional echocardiography or to no screening. The screening and control groups were both all white and evenly split by gender. Approximately 12% of patients self-reported coronary heart disease, 59% had hypertension (though only 13.5% were treated with medication), 32% smoked, and only 4% had diabetes. Screening identified 7.6% of patients with cardiac or valvular conditions and were treated. Over 15 years of follow-up, 26.9% of the participants in the screening group died as compared with 27.6% in the control group (N.S.). Similarly, there was no effect of screening on rates of sudden death, mortality from heart disease, or incidence of fatal and nonfatal myocardial infarction and stroke.
