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
