5] mass and silicon with RV end-diastolic volume
were consistent with RV mass, the confidence intervals were very wide and indistinguishable from no association (Table 2).
Such changes were more pronounced in patients of the second group (compensated CPH) and were accompanied by an increase in the myocardial mass of the left ventricle and by a moderate increase in the end-diastolic volume
and end-systolic volume.
18,20,21) Simplistically, the observed phenomenon is the result of the continuously varying response of the left ventricle to subtle changes in end-diastolic volume
, created through cardiopulmonary interaction.
RV end-diastolic volume
and end-systolic volume were calculated using Simpson's rule.

The heart functions monitored by the researchers included right ventricular ejection fraction (RVEF), end-systolic volume (volume of blood at the maximum contraction point, ESV), and end-diastolic volume
(volume of blood when at the maximum filling point, EDV), stroke volume and cardiac output.
The following parameters were below the level in the control group: left ventricle end-systolic volume (LVESV), left ventricle end-diastolic volume
(LVEDV), stroke volume (SV), cardiac output (Q), stroke volume index (SVI), left ventricle end-diastolic volume
/left ventricular myocardial mass (LVEDV/LVMM), stroke index (SI), left ventricle diastolic function--maximum later peak velocity (peak A) (LVDF-[V.
As a result, we hypothesized that the increased preload, as it related to the increased end-diastolic volume
and contractility, was responsible for the increase in the LV systolic strain.
We studied how the size of LVA affects not only the end-diastolic pressure and the end-diastolic volume
of the whole left ventricle, but also the end-diastolic volume
of section S2 (that developed the LVA).
The 6-month results included a 25% reduction from baseline in left ventricular end-diastolic volume
and a 19% decrease in left ventricular mass.
Similarly, the end-diastolic volume
index dropped from 133 to 103 mL/[m.
He spoke and published widely on the subject but acknowledged that he was not the first to describe the relationship between end-diastolic volume
and the work of the heart.
