Abstract

Objective

To assess the ability of echocardiographic data to predict important functional status outcomes in patients with chest pain.

Design

Prospective cohort study.

Setting

A large, urban teaching hospital.

Patients

Three hundred thirty-three patients admitted from the Emergency Department for evaluation of chest pain.

Measurements and Main Results

Patients underwent two-dimensional and Doppler echocardiography as well as a face-to-face interview during their initial hospitalization and a telephone interview 1 year thereafter. The interview included the Medical Outcomes Study 36-Item Short Form (SF-36) health inventory, a generic health status instrument with a physical function subscale. The relation between clinical and echocardiographic factors and functional status was explored by univariable and multivariable linear regression and logistic regression analyses. Multiple clinical and echocardiographic factors correlated significantly with functional status measures at 1 year. For the SF-36 score at 1 year, age, male gender, white race, the presence of rales, and a comorbidity score were independently predictors in multivariate analysis; echocardiographic findings of severe left ventricular dysfunction (parameter estimate [PE] −27.6; 95% confidence interval [CI] −43.1, −12.2) and aortic insufficiency (PE −16.7; 95% CI −26.4, −7.0) added independent predictive information. Explanatory power (r 2) for models using clinical and demographic variables was .27 and increased after inclusion of echocardiographic data to an r 2 of .35. Results in the subset of patients (n=148) with acute coronary syndromes such as unstable angina or myocardial infarction were qualitatively similar. Selected factors (rales on examination, electrocardiographic changes suggestive of ischemia, and moderate to severe mitral regurgitation) also predicted which patients would die or have a decline in their functional status. In multivariate analysis, only rales remained an independent predictor of poor outcome (odds ratio 2.4; 95% CI 1.2, 4.5).

Conclusions

Echocardiographic data are correlated with measures of functional status in patients with chest pain, but the ability to predict future functional status from clinical or echocardiographic information is limited. Because functional status cannot be predicted adequately from either patients’ characteristics or echocardiographic testing, it must be assessed directly.
