The aim of the study was to differentiate BV, plasma volume, and red blood cell mass profiles by phenotypes of preserved and reduced left ventricular ejection fractions and assess the impact of patient sex on profile heterogeneity.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>METHODS:<\/jats:title>\n            <jats:p>Retrospective analysis of clinical and BV data was undertaken in patients with chronic New York Heart Association II\u2013III heart failure.

HF with reduced ejection fraction was characterized by a higher prevalence of BV expansion \u2265+25% of normal (39% versus 26%;\n              <jats:italic toggle=\"yes\">P<\/jats:italic>\n              =0.003), and HF with preserved ejection fraction was characterized a by more frequent normal BV (42% versus 24%;\n              <jats:italic toggle=\"yes\">P<\/jats:italic>\n              &lt;0.001). Male sex in both phenotypes was associated with a larger absolute BV (7.0\u00b11.6 versus 5.1\u00b11.3 liters;\n              <jats:italic toggle=\"yes\">P<\/jats:italic>\n              &lt;0.001) and higher frequency of large BV and plasma volume expansions above normal (both\n              <jats:italic toggle=\"yes\">P<\/jats:italic>\n              &lt;0.001), while females in both phenotypes demonstrated a higher prevalence of normal BV and plasma volume (both\n              <jats:italic toggle=\"yes\">P<\/jats:italic>\n              &lt;0.001).\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>CONCLUSIONS:<\/jats:title>\n            <jats:p>Findings support significant differences in BV, plasma volume, and red blood cell mass profile distributions between heart failure phenotypes, driven in large part by sex-specific factors.
