Thursday's risk factor: LVH

"LVH is defined as a left ventricular mass exceeding 131 g/m2 of body
surface area in men and 100 g/m2 in women and is the response of the
heart to chronic pressure or volume overload[56]. Its incidence
increases with age, BP and obesity[55]. LVH is independently
associated with increased incidence of cardiovascular disease,
cardiovascular and all-cause mortality, and stroke[57,58]. Effective
BP control in hypertensive patients, along with non-pharmacological
interventions such as weight reduction, sodium restriction and aerobic
physical exercise, can reduce left ventricular mass[59-61]. There are
no conclusive data that the reduction of left ventricular mass can
improve cardiovascular outcome independently of the decrease in BP.
Moreover, there are no standard universally accepted criteria for LVH,
limiting the application of this risk factor in routine clinical
practice[62]. However, LVH is associated with an increased risk of
cardiac events within single studies."

Pseudo-polycythemia causes a .. volume .. overload ..

Increased blood cell / erythrocytosis ..

Hemochromatosis / iron overload presents with
erythrocytosis ..

The snip from a blood donor site below verifies this in that
it calls hemochromatosis / iron overload as a 'category' ..
OF .. erythrocytosis .. too many red blood cells which leads
to hypervolemia ..

<<snip>> Hemochromatosis You may be eligible to donate blood
for others if you have hemochromatosis. To do so you must
present an appropriately completed prescription from your
physician. You must meet all other criteria for volunteer
whole blood donation other than the donation interval.*
Other categories* of erythrocytosis (too many red blood
cells) such as polycythemia vera will remain as therapeutic
phlebotomies per Food and Drug Administration (FDA)
regulations. You can contact South Florida Blood Banks, Inc.
