What is the prognostic significance of LV remodeling measurements like LV dilation or LVESV?

• A. EF is the only prognostic factor.
• B. Greater LV dilation and higher LVESV are associated with worse prognosis; EF is also prognostic.
• C. LV dilation signals better prognosis.
• D. LVESV has no prognostic value.

Answer: (A)

Left ventricular remodeling is a key driver of prognosis in heart failure. When the ventricle dilates or the end-systolic volume (LVESV) increases, the heart works under greater stress, wall stress rises, and contractile efficiency tends to decline. These structural changes track disease severity and independently predict worse outcomes, including higher mortality and more hospitalizations. Ejection fraction (EF) remains a useful measure of systolic function, but it doesn’t capture all the remodeling-related risk. So, greater LV dilation and higher LVESV point to a worse prognosis, and EF also has prognostic value. Choices claiming dilation signals better prognosis or that LVESV has no prognostic value misstate what remodeling measurements indicate.
