Key result
In patients with AMI, the highest quartile of hospital echocardiography use was not associated with differences in inpatient mortality (OR 1.02; 95% CI 0.88-1.19) compared with the lowest quartile.
Why the study?
Guidelines recommend echocardiography after acute myocardial infarction, but little is known about the association between routine echocardiography use and patient outcomes.
Does higher hospital-level use of transthoracic echocardiography improve clinical outcomes in adult patients with acute myocardial infarction?
Population
98 999 hospital admissions for AMI across 397 US hospitals
Comparison
Highest vs lowest quartiles of hospital risk-standardized echocardiography use
Design
Retrospective cohort study
Follow-up
3 months

Higher echocardiography use in AMI was associated with greater costs and length of stay without mortality or readmission benefit; leaves open optimal utilization strategies.

Yes
Does higher hospital-level use of transthoracic echocardiography improve clinical outcomes in adult patients with acute myocardial infarction?
Odds Ratio: 1.02 (95% CI 0.88–1.19)
Higher hospital-level use of echocardiography in AMI patients is associated with increased costs and length of stay without improving inpatient mortality or 3-month readmission rates.
Pack et al. (2019) conducted a cohort in acute myocardial infarction (n=98,999). Highest quartile of echocardiography use vs. Lowest quartile of echocardiography use was evaluated on Inpatient mortality (OR 1.02, 95% CI 0.88-1.19). In patients with AMI, the highest quartile of hospital echocardiography use was not associated with differences in inpatient mortality (OR 1.02; 95% CI 0.88-1.19) compared with the lowest quartile.
