Cardiovascular Exam 2 Cards Flashcards
(223 cards)
Tunica intima
Innermost layer of the artery - elastic and subendothelial layer
Artery endothelium
Inner lining of tunica intima - clot resistant
Tunica media
Vasoconstriction - muscle layer
Tunica externa
Connects arteries to other tissues
Atherosclerosis
Walled off fatty streaks in the arteries
6 steps od atherosclerosis
Fatty streak
Fibrous cap
Disruption of vaso vasorum (nevascularization)
Fibrous plaque (muscle tissue
Advanced lesion
Interplaque hemorrhage
Foam cells
Macrophages that engulf LDL that accumulate into fatty streak and attracts T cells
Stable plaque
Chest pain on exertion
Unstable plaque
Chest pain non exertion dependent
What makes a plaque more unstable
Hemorrhage inside plaque and thin walls
Vaso vasorum makes the plaque grow
Positive remodeling
Increase in vessel size, makes the plaque less stable
Negative remodeling
Results in vessell shrinkage causing more stability
NUmber of heart attacks that are silent
1 in 5
Two groups with abnormal heart attack presentation
Women and diabetics
6 CHD risk equivalents
Clinical CHD
Symptomatic carotid artery disease
PAD
AAA
Diabetes
CKD
4 Statin benefit groups
Clinical ASCVD
LDL greater than or equal to 190 mg/dL
40-75 with DM and LDL 70 to 189
40-75 with 10 year ASCVD risk over 7.5%
2 high intensity statins
Atorvastatin and Rosuvastatin
AAA screening guidlines
65-75 who have smoked - B
Aspirin use guidlines
Class C for 40-59 in 10+% risk - need to assess for bleed risk
Prediabetes screening
Can screen in 35-70 - B
2 populations with abnormal MI presentations
Women and diabetics
Percent of population that has had an MI
3-4% of population
How fast a patient needs to get to the cath lab
90 minutes from start to finish
30 minutes from diagnosis
MCC of MI
Atherosclerosis
