24
Q

class 1

A

no angina with normal act

angina with strenuous exertion

25
class 2
limitation of ordinary act | worse after meals, cold, stress
26
class 3
marked limitation of ordinary activity
27
class 4
angina occurs at rest
28
tissue markers for biomarkers
troponin (specific) myoglobin creatine kinase- MB discriminate bt ischemia and infarction
29
beta blocker
initial therapy in ALL pt with CAD dec angina symptoms dec mortality in post MI, and heart failure B1 rec Anta on SA and AV node
30
cardio selective beta blocker

31
non selective beta blocker
Carvedilol (Coreg®) Propranolol (Inderal®) Labetalol (Normodyne®)
32
beta blocker side effect
``` Hypotension Bradycardia AV block Bronchospasm Lethargy Somnolence Vivid dreams Mask signs of hypoglycemia Except sweating Erectile Dysfunction ```
33
nitrates
Predominantly venodilation Reduces myocardial demand by decreasing preload Relax vascular smooth muscle in the systemic/coronary arteries Provides symptomatic relief No effect on mortality!!!
34
short acting nitrates
SL nitroglycerin or nitroglycerin spray is recommended for immediate relief of angina in patients with CAD • Should be prescribed for ALL patients • Nitromist® • 1-2 sprays onto or SL • Nitrostat® • 0.4 mg SL nitroglycerin tablets • Storage • Must be kept in the manufacturer’s (original) bottle • Discard after 6 to 12 months of opening the bottle • Max of 1.2 mg within 15 minutes • Take at 5 minute intervals • If no relief – CALL 911
35

37
nitrates clinical pearls
avoid with PDE5 inh | hypotension
38
nitrates side effects
