Pulmonary Hypertension Flashcards
Define pulmonary hypertension (PHTN)
Elevated pressures in the arterials in the lungs as a result of RV failure (back up of pressures)
What is the mPAP of PHTN
Compare PHTN and PAH
PHTN is secondary to RV failure and PAH is brought on by structural changes in small pulmonary arteries
What PHTN category is from post capillary stress?
Category 2- PHTN due to LT heart disease
What PHTN categories are from pre capillary causes?
PAH, PHTN due to lung disease, PHTN due to clot in lung, PHTN due to blood and other disorders
What are the signs and symptoms of PHTN?
Symptoms: SOB, coughing, wheezing, hemoptysis
What are the signs of RT CHF?
Jugular vein congestion, peripheral edema, ascites, hepato-splenomegaly
What type of murmur is heard on auscultation with PHTN?
P2 holosystolic (TR)
What are normal RT heart pressures
RA & IVC 0-4mmHg
What is the most common cause for increased RT sided pressures?
Left sided heart failure
What are the 3 pulmonary causes of increased RT side pressures?
Parenchymal, vascular disease, cor pulmonale
What is cor pulmonale
Right sided heart failure SECONDARY to lung condition
Compare acute and chronic cor pulmonale
No RVH in acute as it is sudden,
Chronic there is RVH, RV dilation, RA enlargement due to prolonged pressure overload.
What is Eisenmenger’s syndrome
Shunt reversal, from RT to LT
What are the 3 causes of PHTN
LT sided causes, shunting, embolus
