(44 cards)
What are the types of angina
Stable
Unstable
Variant (Prinzmetal)
What are the classes of angina
0-4
What is the only Tx rationale that works for Prinzmetal
Decrease O2 demand
What are the organic nitrates used for Angina
Isosorbide mononitrate
Isosorbide dinitrate
Nitroglycerin
Sodium nitroprusside
What beta blockers are used for Angina
Acebutolol
Atenolol
Metoprolol
Propranolol
What Ca channel blockers are used for Angina
Amlodipine
Fenoldipine
Verapamil
Diltiazem
What Na channel blocker is used for Angina
Ranolazine
Which antianginals mimic NO
Organic nitrates
Which cause a rapid reduction in myocardial O2 demand
Organic nitrates
Mechanism of organic nitrates
Activate guanylyl cyclase
SM relaxation
Decrease coronary vasoconstriction
Veinous dilation
Which is used as oral angina prophylaxis
Isosorbide mononitrate
What do you use for an ongoing angina attack
Isosorbide dinitrate
What is given sublingual as 1st line Tx for acute angina Sx
Nitroglycerin
What is given in unstable angina and HF
IV Nitroglycerine
What is used for angina in emergency
Sodium nitroprusside
Longer duration than Nitroglycerine
Isosorbide mononitrate
Isosorbide dinitrate
How is nitrate tolerance/desensitization overcome
Nitrate free interval (10-12hrs)
Nitrate contraindication
Pt on Sidenafil
Sidenafil inhibits PDE5 = too much cGMP
Which nitrate can cause CN poisoning
Sodium nitroprusside
Which beta blocker is not cardioselective
Propranolol
Which beta blockers are beta 1 cardioselective
Metoprolol
Atenolol
Main mechanism of beta blockers in angina
Decrease O2 load
Decrease freq/severity of attacks
Decrease HR, contractility
Who do you give beta blockers for angina
Stable angina with LV dysfunction
What happens if you rapidly remove beta blocker
Rebound HTN
