Chapter 104 - lower extremity occlusive disease introduction Flashcards
Percentage of PAD that have CLTI
10%
Progression from IC to CLTI
20%
Prevalence of PAD
5% in age < 50 20% in age > 80
Prevalence of PAD in male vs female
M = F F > M in low SES
Risk factors for PAD
1) Age 2) smoking 2x-4x 3) DM 2x-4x 4) HTN 5) dyslipidemia 6) obesity 7) inflammation 8) homocysteine 9) SES (stress, nutrition, health literacy)
Disease pattern for different risk factors and symptoms
Smoking: AI and FP DM/ESRD: FP and TBP I.C. = single level CLTI = multi level
Asymptomatic PAD cardiovascular risks
2.7x increase mortality 5.6 x increase CAD-related death
Progression from asymptomatic to IC in 5 years
7%
Standard 5 mm treadmill protocol
2 mph with 12% incline
Limb loss risk in IC
< 1%
Typical values for ischemic rest pain
AP < 40 TP < 30 In tissue loss AP < 50 TP < 40
CLI 1 year mortality and amputation risk
22% for amp 22% for mortality
Risk factors for mortality and major amputation in PAD
1) Age > 75 2) CKD 3) CAD 4) CHF 5) DM 6) CVD 7) tissue loss 8) BMI 9) dementia 10) functional state
Bollinger score
Assess severity of arterial disease –> each segment gets its own score
