Cardiology: Pericardial Disease Flashcards
name causes of pericarditis use mnemonic:
CARDIAC RIND
Collagen vascular disease Aortic dissection Radiation Drugs Infections Acute renal failure (uremia) Cardiac (MI) Rheumatic fever Injury Neoplasms Dressler's syndrome
how is pericarditis defined
inflammation of the pericardial sac
name two ways pericardial disease can compromise cardiac output
tamponade or constrictive pericarditis
how does pericarditis present? how does it change with position and breathing
- pleuritic chest pain, dyspnea, cough, and fever
- worsen in supine position and with inspiration
what will be found in examination in a pt with pericarditis
pericardial friction rub
elevated paradoxus (a decrease in systolic BP> 10 mmHg on inspiration)
tampanode
how should pericardial disease be diagnosed?
CXR, ECG, and ECHO to rule out MI and pneumonia
what ECG changes would be expected
diffused ST segment elevation and PR segment depressions followed by T wave inversions
what may ECHO show in pericardial disease
pericardial thickening or effusion may be evident
A 20-yr old male presents with an initial BP of 150/85 mm Hg, and repeat measurement yields 147/85 mmHG. The pt’s potassium level is 3.2mg/dL What is the next step in diagnostic step?
a hyperaldosteronism workup with serum aldosterone and renin levels is an appropriate next step
name treatment of pericarditis (3 steps)
- address the underlying cause or symptoms
- avoid corticosteroids within a few days after MI- to avoid risk of ventricular wall rupture
- monitor for pericardial effusions and use pericardiocentesis as needed
define cardiac tampanode
excess fluid in the pericardial sac, leading to compromised ventricular filling and decreased CO
what is more important in cardiac tampanode. the amt of fluid or the rate of fluid accumulation?
the rate of fluid accumulation
name risk factors of cardiac tampanode
pericarditis, malignancy, SLE, TB, and trauma (stable wounds medical to left nipple)
name triad of cardiac tampanode?
Beck’s triad (JVD, hypotension, distance heart sounds)
how does cardiac tamponade present?
fatigue, dyspnea, anxiety, tachycardia, and tachypnea that can rapidly progress to shock and death
