Why the study?
Does a combination of ECG, heart rate, and natriuretic peptide accurately predict left ventricular systolic dysfunction in primary care patients?
Population
126 patients aged >40 years from primary care with past or present signs or symptoms of heart disease
Comparison
Diagnostic assessment using electrocardiogram… vs Echocardiography (reference standard)
Design
Cross-sectional

May support ECG triage to identify low-risk primary care patients; leaves open prospective validation of combined markers before changing referral practice.
Does a combination of ECG, heart rate, and natriuretic peptide accurately predict left ventricular systolic dysfunction in primary care patients?
A normal ECG implies a very low risk of left ventricular systolic dysfunction in primary care patients, while an abnormal ECG combined with tachycardia or elevated natriuretic peptides identifies high-risk patients needing echocardiography.
