Why the study?

Does echocardiographic measurement of left atrial distensibility and LA ejection fraction improve the identification of elevated left ventricular filling pressure compared to E/e' in patients with stable angina?

Population

174 patients with stable angina and coronary stenosis confirmed by coronary angiography. Excluded: acute…

Comparison

Echocardiographic measurement of left atrial… vs Echocardiographic measurement of E/e'

Design

Cross-sectional

Implication

LA parameters may better identify elevated LVFP than E/e' in stable angina; leaves open prospective validation before practice change.

Structured PICO

Population

174 patients with stable angina (Canadian Cardiovascular Society angina grade I-II) and coronary stenosis confirmed by coronary angiography. Excluded: acute coronary syndrome, previous myocardial infarction, non-sinus rhythm, >mild valvular heart disease, complete bundle branch block.

Intervention

Echocardiographic measurement of left atrial (LA) distensibility and LA ejection fraction (LAEF)

Comparator

Echocardiographic measurement of E/e' (ratio of early diastolic mitral inflow velocity to early diastolic mitral annular velocity)

Outcome

Diagnostic accuracy for identifying elevated left ventricular filling pressure (LVFP >15 mmHg) measured invasively by cardiac catheterizationsurrogate
