Pulmonary Vascular Disease Flashcards
Pulmonary hypertension is a mean pulmonary arterial pressure of what?
mPAP >20-25mmHg
WHO groups 2-3 that are the most common type of pulmonary hypertension
PH due to left HF; & PH due to lung disease
Which WHO group is the most severe, & what is the mortality rate if left untreated?
Group 1, Pulmonary arterial hypertension; Prognosis of 3 years till death if left untreated
Pulmonary hypertension and elevated pulmonary vascular resistance in the absence of heart or lung disease
Pulmonary arterial hypertension
What comorbidity is seen in a patient with PAH?
Scleroderma (an autoimmune connective tissue disorder)
Description of condition: remodeling that causes thickening of the vessel walls and increased vascular resistance and pressure in the LUNGS
Peripheral arterial hypertension
What procedure should be preformed in a patient with suspected PAH?
Right heart catheterization
Exertional Dyspnea, fatigue, syncope;
ECG shows Right ventricular hypertrophy, right atrial enlargement, right axis deviation
Clinical signs of Pulmonary Hypertensionm
CXR showing: prominent pulmonary arteries and ventricular enlargement (name this disorder)
Pulmonary hypertension
BNP level will be high or low in a patient with pulmonary hypertension?
High
If a PT with PAH doesn’t have severe Right HF & responds to vasodilators, what drug class should you prescribe to them?
Calcium channel blocker; Specifically nifedipine
A patient with pulmonary arterial hypertension in the highest risk group, class IV (Emergency) should be treated with what class of drug in what route?
continuous IV Prostacyclin Derivative
A PT with less sever pulmonary arterial hypertension (class II or III; Acceptable or caution) should be TX with what two classes of drugs?
PDE5 inhibitor & Endothelia Receptor Agonist
A patient presents with dyspnea and lightheadedness on exertion, low extremity and abdominal edema, fatigue, lethargy, syncope, chest pain. What is the likely diagnosis?
Cor Pulmonale
Treat patient with oxygen therapy and diuretics to improve oxygenation and Right Ventricular FXN for this disorder
Treatment for Cor pulmonale
