Cause

Symptoms

Fixed splitting S2 and loud P2 heart sound is suggestive of pulmonary hypertension

Lab Findings

pulmonary hypertension initial labs include BNP, CBC, TSH, LFT, ANA
presence of RVH and P pulmonale can suggest pulmonary hypertension
echo findings in pulmonary hypertension includes, high RVSP, TR, and RV dysfunction
large PA size on CT can suggest pulmonary hypertension but does not tell severity
hemodynamics in portopulmonary hypertension

Work up

pulmonary hypertension by groups and workup
pulmonary hypertension is defined by elevated mean pulmonary artery pressure on right heart catheterization
elevated PCWP wedge pressure distinguishes group 2 from groups 1, 3, 4 pulmonary hypertension
normal hemodynamics in right heart catheterization
right heat cath findings in pulmonary hypertension
right heart cath RHC can evaluate for shunt and cardiac output for pulmonary hypertension
right heat cath RHC can be used for vasoreactivity testing during pulmonary hypertension workup
pulmonary vasoreactivity
PVOD pulmonary venoocclusive disease and PCH pulmonary hemangiomatosis

Other pathophysiology

High PCWP in pulmonary hypertension can be beneficial
ESRD patients with AV fistula can cause high cardiac output heart failure and pulmonary hypertension
TAPSE shows how RV is adapting to pulmonary hypertension. Lower TAPSE is associated with higher mortality
cor pulmonale is right heart failure from pulmonary hypertension
sickle cell disease and pulmonary hypertension
drugs associated with pulmonary hypertension
