Ischemic Heart Disease Flashcards
Angina
chest pain, pressure, tightness or discomfort
Stable angina
predictable chest pain, often brought on by physical exertion or stress and relieved within minutes by rest or NTG
Unstable angina
worsening chest pain that is not relieved by rest or nitroglycerin; medical emergency
Prinzmetal’s angina
angina caused by vasospasm of coronary arteries
Often caused by illict drug use, like cocaine
unpredictable chest pain; can occur at rest
Coronary artery disease (CAD)
plaque build up in the coronary arteries, which leads to decreased oxygen supply to the heart
CAD diagnosis
Stress test
Pharmacologic agents used for motionless stress test
Dipyridamole
adenosine
regadenoson
dobutamine
Cardiac catherization
shows how much plaque build-up in the coronary arteries
ASA MOA
irreversibly blocks COX1 and COX2 –> decr in PG and thromboxane A2 –> decr platelet aggregation
P2y12 inhibitor for stable angina
clopidogrel
1st line antianginal agent
Beta blockers
2nd line antianginal agents
CCB (DHP and non-DHP)
Nitrates
Ranolazine
Statin recommendation for stable angina (CAD)
High intensity statin
> 75 y/o: moderate intensity
Preferred treatment for Prinzmetal’s angina
CCB
no beta blockers
Ranexa MOA
inhibits Na current and decr intracellualr Ca; may decr myocardial oxygen demand
Ranexa lowers both HR and BP (T/F)
False, has no effects on HR and BP
Long-acting nitrates require a nitrate free interval, why?
To decrease tolerance (tachyphylaxis)
Nitrate free interval duration
10-12 hours
NTG ointment dosing
BID, 6 hours apart
10-12 hr free
NTG patch dosing
Wear patch for 12-14 hrs, off for 10-12 hrs
rotate app site
isosorbide mononitrate dosing
IR: BID, at least 7 hours apart
ER: in the AM
Isosorbide dinitrate dosing
IR: BID-TID, 8am, 12pm, 4pm; 14 hrs free
ER/SR: daily or BID
Max dose of simvastatin when taking Ranexa
20 mg/day
NTG TL spray priming
Nitrolingual: 5 sprays for new products
1 spray after not using for 6 weeks
NitroMist: 10 sprays for new product
2 spays after not using for 6 weeks
Preferred area to apply NTG patch
chest; in area that is hairless or has trimmed hair
