Patho Exam 3 Flashcards
cardiac specific protein not normally found in serum, released only when myocardial cell death has occurred
troponin
reflects ventricular contraction, the cardiac work phase
systolic
infection of the cardiac endothelium that most commonly affects the heart valves
endocarditis
non-st segment elevation myocardial infarction; occurs when damage is not completely through the heart well, heart attack does not go through the myocardium
NSTEMI
classification of MI based on ECG; ST segment elevation myocardial infarction; occurs because oxygen needs of the myocardium are not met
STEMI
also known as electrical cardioversion, electrical shock that can restore a normal heat rhythm in cardiac arrest or ventricular arrhythmia
defibrillation
durable blood clot
thrombus
enzyme whose function is to regulate BP and filtration rate of the glomerulus
renin
to choke: chronic chest pain that the pt has experienced in the past & feels similar to past episodes
stable angina
a cardiac isoenzyme released & increased from dead myocardial cells
CPK-MB (creatine phosphokinase muscle/brain
death of tissue as a consequence of prolonged ischemia
infarction
chronic inflammatory disease affecting the arterial wall that’s caused by agents that damage the endothelial cells
Plaque build up on arterial wall
this is a common type of arteriosclerosis that develops from plaque buildup
atherosclerosis
inadequate blood flow
ischemia
the heart’s pumping action is restricted because of an accumulation of fluid surrounding it
tamponade
pacemaker other than SA or AV node is initiating a contraction: ventricles are beating independently
premature ventricular contractions (PVCs)
smooth, contagious surface of cells that blanket all the inner linings of the arteries
endothelium
absence of coordinated, rhythmic atrial contractions: rate & rhythm are irregular… this is the most common arrhythmia and can cause thrombus formation so increased risk of stroke
AFIB (atrial fibrillation)
immediate treatment needed for MI: morphine (pain), oxygen (O2), nitrates (vasodilation to increase blood flow to the myocardium, aspirin aka anti-platelet)
MONA
reflects ventricular relaxation, cardiac rest phase
diastolic
chest pain occurring for the first time or is unlike prior episodes; not relieved by rest
unstable angina
decrease in BP that occurs when changing position from lying to standing, this causes a decrease in cerebral perfusion that leads to dizziness
*often experienced by elderly and ppl on antihypertensive meds
orthostatic HTN
what does orthostatic HTN cause? what are the s/s?
causes a temporary internal of inadequate cerebral perfusion
s/s: fainting (syncope), dizzy, weak, tachycardia, diaphoresis
Type of MI when the artery is completely occluded, completely through the heart wall.
*There are also calls ECG changes during this such as T-wave inversion, ST-segment elevation, Q wave development
STEMI (ST Elevation Myocardial Infarction)
Type of MI where the artery is partially occluded causing a milder infarction, subendocardial and not completely thought the heart wall
NSTEMI (Non-ST Elevation Myocardial Infarction)
