Imaging and Diagnostic TestingUtility of B-natriuretic peptide as a rapid, point-of-care test for screening patients undergoing echocardiography to determine left ventricular dysfunction☆
Section snippets
Study population
The study was approved by the University of California Institutional Review Board and conducted at the San Diego Veteran's Health care System between June and October 1999. Two hundred consecutive patients referred for echocardiography to evaluate LV function and consented to be studied were included from a total of 262 patients referred for LV function during this time period. The 62 patients with known LV dysfunction were excluded from analysis. Patients referred for echocardiography to
Results
The characteristics of the 200 patients are shown in Table I. Characteristics of all 200 patients recruited into the study. History included presence or absence of diabetes, hypertension, or coronary artery disease and symptoms included presence or absence ofNo. 200 Age (y) 65.32 ± 0.9 Sex (male/female) 189/11 All normal 53% All abnormal 48% History of hypertension 65% History of diabetes 34% History of coronary artery disease 46% History of shortness of breath 52% History of edema 28%
Discussion
Early detection of LV dysfunction enables administration of treatment that can improve survival and increase well-being.2, 6 But ventricular dysfunction may be difficult to diagnose because patients may be asymptomatic, and abnormal findings on physical examination are often absent.3, 4 Echocardiography, the most commonly used method to diagnose LV dysfunction, is one of the fastest growing procedures in cardiology.25 However, both the limited availability of echocardiography in community
