Chronic Stable angina |
Known issue Occurs with activies that increase HR What to do? Stop, take nitroglycerine SL, then pain goes away |
|
|
Unstable angina |
Hasn't happened before Change in pattern Duration longer, intervention needed, nitro may not help MI (heart damage) could occur |
|
|
Diagnotic Test: Creatine Phosphokinase (CPK) |
Rises around 6 hours and peak at 18 hours Levels decrease to normal in 24-36 hours Can be elevated after muscle injury |
|
|
Diagnostic Test: CK-MB (band of BPK) |
More specific to myocardial muscle damage than CPK |
|
|
Diagnostic Test: Troponin I and T |
Best indicator Troponin I rises in 4-6 hours, peak at 10-24 hours, back to normal in 10-14 days More dardiac specific |
|
|
Diagnostic: CBC |
WBC may be elvated but does not confirm MI |
|
|
Diagnostic: 12 lead ECG |
ST elevation indicates ischemia, progressing toward infarction |
|
