Pulmonary Hypertension / Cor Pulmonale Flashcards
what kind of blood to pulmonary arteries have?
unoxygenated
what kind of blood to pulmonary veins have?
oxygenated
increased pulmonary artery pressure
pulmonary hypertension
what is the normal pulmonary arterial systolic pressure?
less than 30 mmHg
what does pulmonary hypertension lead to in the heart?
increased right ventricle workload
a patient presents with fatigue, SOB, angina, cough, syncope, jugular vein distention, abnormal heart sounds, hepatomegaly, edema, abnormal lung sounds (rales, crackles), and dyspnea. what are they likely experiencing?
pulmonary hypertension
what is the gold standard for diagnosis and pressure measuring of pulmonary hypertension?
right-sided cardiac catheterization
what is the diagnostic used to assess cardiac disease and estimate right ventricular systolic pressure?
echocardiogram with doppler flow
what type of medication is used for the vasodilator challenge during right heart catheterization?
CCB
what are the 3 steps of treatment for pulmonary hypertension?
- treat underlying cause
- supplemental O2
- oral CCB if positive response
what can be used for a patient with pulmonary hypertension that does not respond to CCB/vasodilator?
oral endothelin receptor antagonists
the result of pulmonary hypertension that is worsening, also known as pulmonary heart disease or failure
Cor Pulmonale
what is the cause of Cor Pulmonale?
right ventricle dysfunction or failure
a patient presents with fatige, SOB, angina, cough, syncope, respiratory distress like tachypnea, accessory muscle use, edema, and can lead to respiratory failure. what are they experiencing?
cor pulmonale
what 2 diagnostics can be used to diagnose a patient with cor pulmonale?
EKG
CXR
