HTN, Secondary prevention of MI (metoprolol +
Indications for Beta Blockers
carvedilol), Cardiac arrhythmias, angina, Afib,
CHF/Systolic HF
Decreases HR/BP, negative inotrope by decreasing
Effects of B Blockers myocardial workload, decreases preload, blocks stress
catecholamines (epi + NE), decreases
morbidity/mortality, decreases arrhythmias
What should you monitor for Low HR, Low BP, AV Blocks, HF, signs of shock, bronchospasm;
in B blocker administration? cocaine use
B blocker reversal agent Glucagon
How do Angiotensin They block AT1 receptors that hormones act on which
Receptor Blockers work? are found in the heart, blood vessels, and kidneys.
Block Angiotensin 2 to help lower BP
Examples of ARBS "sartans"; Losartan, valsartan, candesartan, olmesartan, telmisartan
Indications for ARBs HTN, CHF/Systolic failure, diabetic renal nephropathy,
intolerance of ACE inhibotors
Effects of ARBs Vasodilation, decreases preload and afterload, reduces secretion
of vasopressin.
Hypotension, HyperK, HA, caution in MI; second line
Watch out for these s/sx of
ARBs drug use for pts that cant tolerate ACE inhibitors
Examples of Aldosterone Spironolactone and eplerenone

perfuse?
20% of the population has it. Tertiary left main; runs
Ramus artery
along the LV, between the LAD & circumflex
Systemic Vascular Resistance- the resistance the LV has
SVR
to overcome to eject. (Afterload)
PVR Peripheral vascular resistance: the resistance the RV has to
overcome to eject
S1 Closure of the MV and TV; Systole; 1/3 of the cardiac cycle "Lub"

KENTUCKY
S3 is normal in which Normal in kids, high CO like pregnancy (3rd trimester)
popuation(s)?
Atrial gallop (pre-systolic); sound caused by vibration of
S4
atria ejecting into non compliant ventricle; Tennessee
Causes of S4 Ischemia, HTN, pulmonary stenosis, CAD, AS, LV Hypertrophy
When are Split Heart sounds Inspiration
heard best?
Split S1 MV closes b/f tricuspid
Causes of Split S1 RBBB, PVCs, Ventricular Paced rhythms
Split S2 Aortic closes b/f pulmonic valve
Causes of Split S2 Overfilled RV, ASD
CHF/Systolic Failure, AMI (EF <40%), Anterior wall MI,
HTN, Diabetic Renal Nephropathy
Indications for ACE Inhibitors
-prils Angiotensin Converting Enzyme
Vasodilation, decrease preload & afterload, prevention
Effects of ACE Inhibitors
of myocardial remodeling, reduce progress of diabetic
nephropathy
What do you want to monitor Hypotension, hyperk, cough/angioedema, renal function
