Left Atrial Volume
A Powerful Predictor of Survival After Acute Myocardial Infarction
Circulation. 2003;107:2207
Conclusions— Increased LA volume index is a powerful predictor of mortality after AMI and provides prognostic information incremental to clinical data and conventional measures of LV systolic and diastolic function.

Predictive Value of Normal Left Atrial Volume in Stress Echocardiography
J Am Coll Cardiol, 2006; 47:1024-1028
CONCLUSIONS: Normal resting LAVI (≤28 ml/m2) was strongly predictive of a normal stress echocardiogram. Left atrial volume index might be a simple means of identifying patients with low ischemic risk and should be further evaluated as a complement to the assessment of ischemic risk.

Long-term prognostic significance of left atrial volume in acute myocardial infarction
Am Coll Cardiol, 2004; 44:327-334
CONCLUSIONS: In patients with acute MI, increased LA volume, determined within the first 48 h of admission, is an independent predictor of five-year mortality with incremental prognostic information to clinical and echocardiographic data.

Left atrial volume provides independent and incremental information compared with exercise tolerance parameters in patients with heart failure and left ventricular systolic dysfunction
Heart 2007;93:1420-1425
Conclusion: LAV provides powerful prognostic information incrementally and independently of VO2. LAV, EF and VO2 can be used to build a risk prediction model, which can be used clinically.
