MKSAP Flashcards
Acute pericarditis dx
1) Pleuritic chest pain
2) Friction rub (squeaky, scratchy, high pitched)
3) Diffuse concordant ST elevation (PR depression)
Also: worse lying down
Aortic dissection presentation
Sudden onset severe chest pain radiating to back
BP difference between R and L arms
Murmur of AR
Widened mediastinum on CXR
RV MI
Findings: hypotension, clear lungs, elevated CVP (JVD)
Tx with normal saline then IV dobutamine if still hypotension after 1L saline
ST elevation in II, III, aVF but also V4
Medical therapy for chronic stable CAD
Antianginal: beta blockers, CCBs, nitrates
Vascular-protective therapy: aspirin, ACE inhibitors, statins
Workup of CAD
Exercise stress test is best
Adenosine nuclear perfusion stress test should NOT be done in asthma pts
Dobutamine stress echo should NOT be done in those that can exercise or those that are hypertensive
V-tach
After structural damage such as MI
Wide QRS (>0.12 sec)
Cannon waves (large a waves) suggest v-tach or heart block (AV dissociation)
Complications after MI
Papillary muscle rupture –> severe MR (several days later)
Ventricular free wall rupture –> CV collapse, tamponade, PEA, sudden hypotension then death (1-4 days later)
VSD –> systolic murmur, hypotension, resp distress, thrill (2-7 days after)
LV aneurysm –> intractable v-tach, septic emboli, heart failure (much later)
CHADS2
Whether or not pt with a-fib should be on warfarin
INR 2-3 decreases stroke risk 62%
3 or more points means YES warfarin
CHF
HTN
Age > 75
DM
Stroke (2) or TIA (1)
Digoxin use
Used in patients with CHF for SYMPTOMS (no mortality benefit)
Use low doses (0.5-0.8 ng/mL)
Treatment of heart failure
All stages of systolic heart failure: beta blocker
NYHA Class III or IV: beta blocker, ACE inhibitor, spironolactone
How to treat HTN or angina in pt with CHF already on beta blocker and ACE inhibitor
CCBs that aren’t bad in CHF: amlodipine, felodipine
Antibiotic endocarditis prophylaxis
Prosthetic valve
Hx infective endocarditis
Cardiac transplant with valve abnormality
Unrepaired cyanotic congenital heart disease
Complex congenital heart disease w/residual abnormalities
Chronic pancreatitis
Clinical presentation: mid-epigastric pain, diarrhea after eating, DM 2/2 pancreatic endocrine insufficiency
Malabsorption occurs when 80% of pancreas destroyed
Serum to ascites albumin gradient (SAAG)
Serum albumin - ascites albumin
>1.1 means ascites is due to chronic liver disease: cirrhosis, RHF, Budd-Chiari
<1.1 means due to infection, inflammation, cancer, TB, nephrotic syndrome
Hepatic encephalopathy triggers and treatment
Triggers: infection (SBP), dehydration, GI bleeding, diet, medications
Treatment: lactulose to 2-3 BM per day at pH < 6
