|
Term
| Myocardial cell injury (damage) occurs when the ischemic process is more severe. |

|
Definition
|
|
Term
| Changes in the intimal lining of the arteries..It begins as a fatty streak, builds fibrous plaque, & becomes a complicated lesion that can block off an artery. |

|
Definition
|
|
Term
| Caused by arrhytmias, pulmonary embolism, hypotension, or shock |
|
Definition
| Decreased coronary artery blood flow |

|
|
Term
| Other causes for Ischemic heart disease |
|
Definition
Congenital coronary anomalies
&
Coronary artery thrombosis |
|
|
Term
| CP due to myocardial ischemia: |
|
Definition
|
|
Term
| An effort-induced CP, lasts seconds to minutes and is relieved by rest or NTG. |
|
Definition
|
|
Term
| Tends to last longer, occurs more frequently, is not necessarily due to effort, and may be temporarily relieved by NTG |
|
Definition
|
|
Term
| Occurs at rest, in the early hours of the morning, is often associated with ST segment elevation, and is thought to be from a CA spasm |
|
Definition
Varient Angina
(Prinzmetal's) |
|
|
Term
MI can be silent (mild/nonexsistent symptoms)
TRUE or FALSE |
|
Definition
|
|
Term
| Immediate goals for Ischemic heart disease include: |
|
Definition
Pain management,
oxygen to myocardium,
prevent platelet aggregation,
restore CA blood flow, and salvage myocadium |
|
|
Term
|
Definition
| morphine, oxygen, nitroglycerin, aspirin |
|
|
Term
| Cath Lab provides options such as: |
|
Definition
| PTCA, atherectomy, and coronary artery stent |
|
|
Term
| According to the World Health Org.there are 3 criteria for an MI : |
|
Definition
1. History of severe, prolonged CP
2. Unequivocal EKG changes /
abnormal & persistant Q waves
3. Changes in serial cardiac biomarker
levelsthat indicate MI or Infarction |
|
|
Term
| Cardiac Cath is _____ to determine the presence, location, & severity of CAD. |
|
Definition
|
|
Term
| Serum cardiac biomarkers used to detect injury and infarct are: |
|
Definition
| Creatine kinase (CK) aka (CPK) enzyme, CK-MB (muscle enzyme) & Troponin T |
|
|
Term
| Creatine kinase (CK) aka (CPK) enzyme, CK-MB (muscle enzyme) are released with: |
|
Definition
Tissue Necrosis.
Blood levels increase 4-6 hrs after infarct.
& return to normal 24-48 hrs later |
|
|
Term
| Troponin T is more specific to: |
|
Definition
Cardiac infarction.
It rises 3-5 hrs after MI and
remains elevated up to 21 days later. |
|
|
Term
| An inflammatory process involving the parietal and visceral layers of the pericardium that may lead to pericardial effusion. |
|
Definition
|
|
Term
| A collection of fluid within the pericardial space (parietal & visceral layers) and is a common response to an acute MI. |
|
Definition
| Pericardial Effusion (PE) |
|
|
Term
| A post MI illness that presents with fever, pericarditis, PE, & pleuritis. May present weeks or months after MI. |
|
Definition
|
|
Term
| A bulge in the LV wall that persists during diastole and systole with akinesis or dyskinesis. A hinge point where good myocardium meets bad. |
|
Definition
| Left Ventricular True Aneurysm |
|
|
Term
| A narrow perforation of the LVFW with a false chamber. It usually has a saccular or globular contour. |
|
Definition
| Left ventricular pseudo-aneurysm |
|
|
Term
| When there is an akinetic or dyskinetic area, the blood tends to pool and thrombus develops. It is commonly located at the apex. |
|
Definition
| Left ventricular thrombus |
|
|
Term
| Most often associated with an inferior MI and results in MR. |
|
Definition
| Papillary muscle dysfunction |
|
|
Term
| It is rare and is most often associated with an inferior MI. |
|
Definition
| Right ventricular infarction |
|
