Abstract
Background:
The increase in viscosity caused by secondary polycythemia is thought
to be one of the major causes of pulmonary hypertension secondary to
chronic emphysema. However, very few clinical studies considered the
relation between pulmonary hypertension and polycythemia in the case
of chronic obstructive pulmonary disease.
Objective:
The purpose of this study is to elucidate the relative contribution of
an increase in hemoglobin level (Hb) to mean pulmonary arterial
pressure (mPAP) and pulmonary vascular resistance (PVR).
Methods:
We retrospectively investigated 41 patients with chronic emphysema who
had undergone a right heart catheterization. Multiple-regression
analysis and F test were performed to investigate both direct effects
of Hb and PaO2 as independent variables on mPAP and PVR as dependent
variables.
Results:
Significant correlations were found between PaO2 and mPAP (or PVR), or
Hb and mPAP (or PVR), indicating that both Hb and PaO2 are
contributory to mPAP and PVR. The F test demonstrated that Hb and PaO2
could directly affect the level of either mPAP or PVR.
Conclusions:
It was concluded that Hb had a direct effect on mPAP and PVR,
independently of hypoxia in patients with chronic emphysema.

"Chronic pressure overload of pulmonary hypertension"
This can be caused by erythrocytosis / polycythaemia .. which ..
coincidentally .. HAPPENS .. in this incidence.
Therefore in theory erythrocytosis / increased red blood cell
production could BE THE **cause** OF pulmonary hypertension down here
amongst those normally residing at sea level.
Spoor.
Increased red blood cells happens only in a few ways.

This is in accord with Starling's law.

Pulmonary hypertension may lead to "cor pulmonale". In this disorder,
the right ventricle, which pumps blood to the lungs,
becomes enlarged,eventually resulting in right sided heart failure.
The enlargement of the right-ventricle occurs to compensate for its
weakening from the chronic pressure overload of pulmonary
hypertension.

May you and other dear neighbors, friends, and brethren have a
blessedly wonderful 2008th year since the birth of our LORD Jesus
Christ as our Messiah, the Son of Man ...
... by being hungrier:

Hunger is wonderful ! ! !
It's how we know what GOD desires, which is all that is good.
Yes, hunger is our knowledge of good versus evil that Adam and Eve
paid for with their and our immortal lives.
"Blessed are you who hunger NOW...
... for you will be satisfied." -- LORD Jesus Christ (Luke 6:21)
Amen.
Here is a Spirit-guided exegesis of Luke 6:21 given in hopes of
promoting much greater understanding:

Be hungrier, which is healthier.

Prayerfully in the awesome name of our Messiah, LORD Jesus Christ,
Andrew
