Increased prevalence of cerebral microbleeds in patients with low left ventricular systolic function.

abstract：:We have theoretically proposed "systolic pressure-volume area" (PVA) as a measure of total mechanical energy generated by ventricular contraction. We then experimentally showed that PVA closely correlates with left ventricular oxygen consumption (Vo2) regardless of ventricular loading conditions in a stable contractil...
