What is angina?
chest pain
Angina is a manifestation of?
reversible myocardial ischemia
What causes angina or chest pain?

3. has a 5-15 minute duration
What does a 12-lead electrocardiogram (ECG) often show in chronic stable angina? 2
1. ST segment depression
2. and or T-wave inversion
What does an ST segment depression and or T-wave inversion indicate?
ischemia
How is chronic stable angina controlled? *
with drugs on an outpatient basis
What are the different types of chronic stable angina? 5
1. silent ischemia
2. nocturnal angina
3. angina decubitus

What is silent ischemia? *
ischemia that occurs in the absence of any subjective symptoms
Silent ischemia is associated with?
diabetic neuropathy
How do you confirm silent ischemia? *
ECG changes with a Holter monitor
What is nocturnal angina? *
chest pain that occurs only at night but not necessarily during sleep
What is angina decubitus?
chest pain that occur only while lying down
How is angina decubitus relieved? *
by standing or sitting
What is prinzmetal's (variant) angina? *
rare form of angina that often occurs at rest usually in response to a spasm or a major coronary artery
Prinzmetal's (variant) angina is seen in patients with a history of? 3
1. migraine headaches
2. raynaud's phenomenon
3. heavy smoking
TRUE OR FALSE: In prinzmetal's (variant) angina, spasm may occur in the absence of CAD.
TRUE
What is microvascular angina? *
chest pain that occurs in the absence of significant atherosclerosis or coronary spasm
In microvascular angina, chest pain is related to? *
myocardial ischemia that is associated with atherosclerosis or spasm of the small distal branch vessels of the coronary microcirculation
Chest pain that is due to myocardial ischemia from atherosclerosis or spasm of the small distal branch vessels of the coronary microcirculation is known as?
coronary microvascular disease (MVD)
Coronary microvascular disease (MVD) affects?
small, distal coronary arteries
What is the goal of collaborative care for CAD? *
decrease oxygen demand and or increase oxygen supply
What is the first line drug therapy for the treatment of angina?
short-acting nitrates
What is the mechanism of action of short-acting nitrates? *
dilates peripheral and coronary blood vessels
What are some examples of short-acting nitrates? 2
