Bardes Flashcards
Unstable angina versus MI?
ST depressions, T-wave inversions, but no troponin elevation
Chest pain – rule out? (How?)
- M I – troponins/EKG
- PE – d-dimer/CT/VQ scan
- Aortic dissection – TEE, chest x-ray
- Pneumothorax – x-ray
- Pericarditis – EKG
MI treatment?
OH BATMAN Oxygen Heparin Beta blocker Aspirin Thrombolytics Morphine Atorvastatin Nitroglycerin
When to give thrombolytics over Cath Lab?
If Cath Lab, need what backup?
If Cath Lab is far away
Need CT surgery back up
Best response to aggressive patient with altered mental status?
Give 1:1
When to perform a coronary artery bypass graft?
Three vessel disease or left main stenosis
Problem with morphine for MI treatment?
Mask symptoms
Severe chest pain with nausea and vomiting – think?
Inferior wall MI – phrenic nerve activation causes nausea and vomiting
Any patient with a stent needs to be put on which drug? For how long?
Clopidogrel
1 month if bare-metal stent
12 months if drugs-eluding stent
Drugs appropriate for stable angina?
Drug appropriate for unstable angina and MI?
Drugs appropriate for MI only?
Aspirin, beta blocker
Aspirin, Plavix, heparin, beta blocker
+Thrombolytics
Complicated UTI?
- Men or pregnant women
- Diabetics/renal failure
- History of pyelonephritis last year
- Urinary track obstruction (indwelling catheter, stent, nephrostomy tube)
- Antibiotic resistant organism
- Immunocompromised
SIRS criteria?
- Temperatures over 30 or less than 36
- RR over 20 or PaCO2<32
- Heart rate over 90
- WBC over 12 or under 4
Three different types of shock and physical exam findings (Temperature, venous distention, pulse)?
Hypovolemic shock (cool, flat veins, weak pulse)
Cardiogenic (cool, JVD, weak pulse)
Decreased peripheral resistance (septic, toxic, neurogenic) (warm, flat veins, strong pulse)
Shock - treatment?
- IV fluids until CVP is 8 to 12, MAP greater than 65, SPO2 greater than 70
- 1 If no response - pressors (dopamine, then epinephrine)
- 2 If no response Dobutamine
- Broad-spectrum antibiotics (Ceftriaxone, then vancomycin + zosyn)
Causes of cardiogenic pulmonary edema?
- Systolic dysfunction (decreased LV contractility)
- Diastolic dysfunction (decreased LV compliance)
- Mitral stenosis
Causes of systolic dysfunction?
- Ischemia
- dilated cardiomyopathy
- valvular disease
- arrhythmia
- myocarditis
- Milieu (electrolytes, thyroid hormone)
- Drugs (doxorubicin, alcohol, beta blockers, calcium channel blockers)
Drug that causes permanent systolic dysfunction?
Doxorubicin
Causes of diastolic dysfunction?
- Acute ischemia
- Thickened LV (hypertension, aortic stenosis, aortic coarctation, hypertrophic cardiomyopathy)
- Restrictive cardiomyopathy (sarcoid, amyloid, hemochromatosis, Gaucher’s disease)
Systolic versus diastolic dysfunction – characteristic heart sound?
S3 versus S4
8 causes of secondary hypertension (and lab values needed to confirm)?
Kidney causes, hormone causes, drug causes
- Pheochromocytoma (serum catecholamines/urine metanephrines)
- Renovascular (renin)
- Real insufficiency (creatinine)
- Hypo/hyperthyroid (TSH)
- Cushing’s/adrenal hyperplasia (cortisol)
- Conns (aldosterone)
- Amphetamine/cocaine (urine toxicology)
- Sedative withdrawal
Treatment for systolic LV dysfunction that has a mortality benefit?
- ACE inhibitors
- Beta blockers (metoprolol, busiprolol, Coreg)
- Aldosterone receptor antagonists (spironolactone)
- Combination nitrates and hydralazine (and African-Americans)
- ARBS
Functions of beta blockers?
- Decrease afterload
- Increase filling
- Antiarrhythmic (mortality benefit)
- Less Remodeling
Advice for treatment for systolic LV dysfunction?
- Give lots of drugs in the highest dose (as long as heart rate and blood pressure can tolerate)
- Do not give ACE inhibitors, ARBs, and beta blockers in combination
Treatment for systolic LV dysfunction that do not have a mortality benefit?
- Digoxin
- Diuretics
- Nitroglycerin/nitrates alone
- Hydralazine alone
Treatment for diastolic left ventricular dysfunction?
- Beta blockers (decrease heart rate to increase feeling time)
- Calcium channel blockers
Non-cardiogenic causes of fluid in alveolar space?
- Infection
2 ARDS - Sepsis
- Trauma
