Cardiovascular Flashcards
(51 cards)
Stable angina tx
- BB (decrease heart rate and contractility thus decreasing O2 demaind)
- CCB (dont use with BB cause can cause heart block) promote coronary and peripheral vasodilation and reduce contractility
- Nitrates
- ASA
tx of acute coronary syndrome (Unstable angina, NSTEMI, STEMI)
-ABCs
-MONA BASH C
Morphine, oxygen, nitrates, aspirin/antiplatlet (clopidogrel or tecagrelor), BB, ACE-I, Statin, Heparin (exnoxaparin if no PCI and unfractionated heparin if undergoing PCI), Clopidogrel
- Check electrolytes (Mg and K)
Long term management of MI
BASA’S and Lifestyle
*BB
*Aspirin and or clopidogrel
Spironolactone (aldo inhibitor so assists ACE-I)
*ACE-I or ARB
Statin
*decrease mortality
Prinzmetal angina tx
- SMOKING CESSATION
- CCB (diltiazem)
- Nitrates
- Avoid nonselective BB (B2= vasodilation) and triptans (associated with coronary artery vasospasm)
- Aspirin should be used with caution and at low dosage bc inhibits prostacyclin
aortic stenosis tx
aortic valve replacement if symptomatic (dyspnea, syncope, angina)
mitral regurg tx
- vasodilators for LV dysfunction
- anticoagulate pts with afib or hx of rheumatic heart dz
- mitral valve repair
aortic regurg tx
medical management of heart failure (ACE-I, BB, spironolactone)
Aortic valve replacement
mitral stenosis tx
balloon valvuloplasty
diuretics for CHF sxs prior to valvuloplasty
anticoagulate pts with Afib
what’s Ficks priciple
CO= Rate of O2 consumption / arterial O2 content - venous O2 content
what are the 3 equations for MAP
MAP = CO X TPR MAP = DBP + 1/3 PP MAP = 2/3 DBP + 1/3 SBP
What is the equation for LVEF
SV/EDV
or
EDV-ESV/EDV
HOCM tx
BB
Restrict physical exertion
Avoid volume depletion and dehydration
dilated cardiomyopathy tx
diuretics, ACE-I, BB
Restrictive cardiomyopathy tx
Identify and tx underlying cause
Diuretics, ACE-I, BB
tx of acute decompensated CHF presenting with pulmonary edema
NO LIP
- Nitrates (nitroglycerin or nitroprusside)- redistributes blood outside the pulmonary vasculature back to the systemic
- oxygen (if hypoxic)
- Loop diuretics
- inotropic drugs (dobutamine, milrinon- both not first line), -positioning
which drugs proven to reduce mortality in CHF pts
ACE-I
BB (Bisoprolol, carvedilol, and extended release metoprolol)- avoid starting in pts with acute decompensated HF
aldo- antagonist (spironolactone, eplerenone)
*nitrates and diuretics help sxs but dont decrease mortality
What drugs are useful to relieve sxs in chronic CHF
Loops, digoxin, vasodilators (isosorbide dinitrate, hydralazine)
Hypovolemic shock tx
Fluids
Cardiogenic shock tx
Dobutamine (B1 agonist), Intra-aortic balloon pump
be careful with fluids!
obstructive shock tx
treat underlying extracardiac cause (ex. tension pneumo, hemothorax, PE)
If cardiac tamponade, do a pericardiocentesis
septic shock tx
IVF, Norepi (vasoconstriction > increased CO), abx
anaphylactic shock tx
Epi, IVF, airway management
neurogenic shock tx
IVF, vasopressors, atropine for bradycardia
myocarditis tx
abx for bacterial cause
stop offending drug
treat any arrhythmias
+/- immunosuppressive agents if autoimmune
supportive treatment bc mycocarditis is MC due to viruses!
