what will decrease oxygen supply to heart to heart?
tachycardia
What drug will increase oxygen supply and decrease oxygen demand in the heart?
beta blockers
what imaging will tell you about the vessel wall?
intravascular ultrasound
pt comes in with unstable angina, what is the FIRST thing you do?
IV nitroglycerin
most common CABG grafts?
- mammary artery
2. saphenous vein
rate limiting step in the formation of cholesterol is
HMG coA reductse
knowing the Apo Lipoportein B is important because it
measures the number of potentially atherosclerotic particles in the blood
characteristic of stable plaque s
- fibrous
- calcified
- lipid content
- less inflammation
- less apoptosis
NO is secreted by the
endothelium
arterial thrombi characteristics?
- treated with antiplatelets–platelet rich
- can complicate atherscletoric plaque rupture
- can be cardioembolic or insitu

For which groups of patients does taking a daily Aspirin have a proven net benefit in CV risk reduction (ie. risks outweigh the benefits)?
Any patient with CAD
Your attending prescribes Isosorbide-5-minonitrate (ISMO) and Metroprolol for a patient with chronic stable angina. Which of the following could be a reason your attending chose Metroprolol instead of Nifedipine?
ISMO can cause reflex tachycardia, which will be controlled by Metroprolol and exacerbated by Nifedipine
Variant angina treatment medication
calcium channel blocker acts as a smooth muscle relaxer and suppresses the vasomotor tone and spasms
A patient presents with chronic stable angina with variable threshold (reduced myocardial blood supply is caused by alterations in coronary vasomotor tone). The patient also has mild CHF (for which the patient does NOT take digitalis). Which of the following drugs would be appropriate to prescribe this patient, and why?
Amlodipine, because it is a potent vasodilator and causes minimal reduction in inotropy.
claudication is described as
caused by reversible calf muscle ischemia, during exercise
A 51 year-old patient has CHF. His labs show significantly elevated B-type natriuretic peptide. What can you conclude based on this information?
He has an increased left ventricular end diastolic pressure (LVEDP)
