List 7 primary risk factors for CAD?
|
Age
FH of early CAD Smoking HTN Male gender Elevated LDL DM |
|
|
How do you calculate LDL and what do the levels mean?
|
LDL= Total Chol -HDL -1/5 Triglycerides
>160 = high risk 130-159 = borderline high 101-129 okay <100 higly desirable May be falsely low 2 months after and MI or cardiac surgery |
|
|
What effect to statins have on plaque architecture?
|
Plaque stabilizaion
|
|
|
Criteria for CABG vs PCI
|
CABG improves survival and sx in Left Main dz and 3 vessel dz with LV dysfunction (EF <50%) CABG improves sx of angina in 1-2 vessel dz but does NOT affect survival
PCI suitable for multivessel CAD with amenable anatomy, nml LV function without DM |
|
|
What pt group should definetly get PCI?
|
multivessel dz
nml LV function no DM suitable anatomy |
|
|
What increses/decreases HDL?
|
Increase - Exercise, estrogen, small mts of ETOH
Decrease - smokinng, androgens |
|
|
What are the graft survival rates?
|
saphenous vein 70% occlusion in 10 yrs
Internal mammary 90% patency at 10 yrs |
|
|
what is the impact of balloon angioplasty on survival, stenosis patency rates, complication rates
|
No impact on survival proved
35-55% symptomatic restenosis within 6 months. If still open at 1 yr 65% will remain open at 5 yrs. 1% mortality, 2% MI, 3% emergent CABG (this is decreasing) |
|
|
Where & how does restenosis occur after balloon angioplasty?
|
At the plaque fracture site thombosis is initiated leading to intiamal hyperplasia, and media smooth muscle proliferation & finally a fibrotic buldge.
