tut 1 angina Flashcards
what is the difference between nondenuding and denuding injury

steps in forming atheroscholerosis

what is collateral circulation
when atherosclorosis develop, the microcirculation become macrocirculation for blood supply.

what r the manifestation of CAD
Manifestations
Angina Pectoris
Acute Coronary Syndrome
Sudden Cardiac Death
Relationships Among CAD, Stable Angina, and MI

types of Angina Pectoris
- Silent Ischemia - associated with diabetes & HT
- Prinzmetal’s Angina
- Nocturnal Angina – not necessarily asleep
- Angina Decubitus - chest pain while lying down and is relieved by standing or sitting
- Unstable Angina Pectoris UAP
how acute coronary syndromes develop

acute coronary syndromes
- partially occluded VS totally occluded
Prolonged ischaemia, not immediately reversible
Deterioration of a once stable atherosclerotic plaque
Partially occluded
- Unstable Angina pectoris
- Non ST segment elevation MI (NSTEMI)
Totally occluded
- ST segment elevation MI (STEMI)
unstable angina pectoris
Chest Pain
- New onset
- Occurs at rest
- Different pattern
Fatigue
Shortness of breath
Indigestion
Anxiety

NSTEMI or STEMI
Sustained ischaemia causing irreversible myocardial cell death
80-90% thrombus formation
Location of damage Transmural (see image) Subendocardial
what is the hallmark for myocardial infaction
pain

clinical menifestation of NSTEMI and STEMI

Immediate management of ACS – “priorities”

when is indicative change and reciprocal change occur
Indicative changes occur in leads that examine the area of infarction. Reciprocal changes occur in leads opposite the area of infarction

what does different lead look for on ECG

Serum cardiac markers in the blood after MI

objective data on cardiac assessment

objective data on cardiac assessment

immediate and long term treatment goal for ACS

nursing management on ACS
