|
Definition
|
|
Term
| difference btwn unstable angina and NSTEMI: |
|
Definition
| NSTEMI has elevated cardiac markers |
|
|
Term
| initiating event in most MIs is believed to be: |

Definition
| thrombus on top of an ulcerated or cracked athersclerotic plaque |
|
|
Term
| nearly all infarcts are located n the: |
|
Definition
|
|
Term
| which coronary artery accounts for up to 1/2 infarcts? |
|
Definition
|
|
Term
| 3 promary indicators for Dx of MI: |
|
Definition
1. S/Sx
2. EKG
3. Elevated cardiac markers |
|
|
Term
|
Definition
1. CP
2. Refered Pain
3. Nausea
4. Vommiting
5. Diaphoresis
6. SOB |
|
|
Term
| diff btwn angina and infarct pain: |
|
Definition
| infarct pain lasts longer than 15min and is not relieved by rest or nitro |

|
|
Term
| represents ischemic cells that have not yet become necrotic: |

|
Term
| abnormal ion flux results in continuous current flow even when heart is at rest; this current flow may be see on the EKG as: |
|
Definition
|
|
Term
| infarcted muscle that is necrotic and no longer electrically active on EKG: |
|
Definition
| Q waves and inverted T waves |
|
|
Term
| NSTEMI shows what on EKG: |
|
Definition
| ST depressions or T wave changes |
|
|
Term
| pts w ACS that do not develop elevations of cardiac markers are Dx with: |
|
Definition
|
|
Term
| what are two major goals of Tx for ACS: |
|
Definition
1. decrease myocardial O2 demand
2. increase O2 supply |
|
|
Term
| 3 drugs that decrease myocardial workload: |
|
Definition
| 1. Beta Blockers (O2 sup & wrkload)
3. morphine (vasodilator >O2 sup & workload) |
|
|
Term
| 7 Tx for ACS that would increase O2 to ischemic areas: |
|
Definition
1. O2 admin
2. Anti-platelet (ASA)
3. Thrombolytic
4. Anticoag (heparin)
5. angioplasty
6. stent placement
7. CABG |

|
Definition
1. SNS (>HR,>venoconstriciton,
2. Renin/Angiotensin
3. Hypertorphy (from compensatroy measures) |
