– Presentazione clinica della PAD • Asintomatica ( aterosclerosi occulta ) • Sintomatica ( claudicatio intermittens ) • CLI ( Ischemia critica cronica )

– Raccomandazioni TASC 2 per lo sreening dei pazienti con PAD asintomatica • Soggetti con una storia, o visita medica , suggestiva di PAD( B ) • Pazienti a rischio PAD ( tra 50 e 69 anni con storia di diabete o fumo, o chiunque abbia più di 70 anni ) ( A ) • Pazienti con un Framinghamrisk score di 10% -20% in 10 anni ( B ) • Concomitanza di malattia carotidea cardiaca o renale
Sig.ra Maria • Donna • 60 anni • Madre deceduta per ictus • Padre vivente; cardiopatia ischemica • Impiegata • Sposta; due figli • Palestra 2 volte a settimana • Fuma 15 sigtte/die dall’età di 17 anni • Non diabetica • Colesterolo 230 mg/dl • LDL 110 mg/dl • Trigliceridi 201 mg/dl • BMI 28 • ECG negativo • PAO 140/80 mmHg

Sottoporre la paziente ad indagini per Aterosclerosi occulta, sarebbe una buona idea ????
ABI - Definition Ankle systolic pressure Brachial systolic pressure RATIO
EquipmentformeasurementofAnkle/BrachialIndex (ABI) Doppler CW Probe 8 mHz Sphygmomanometer
Calculation of Ankle/Brachial Index Right ABI Higher of the rigth ankle systolic pressure (dorsalis pedis or posterior tibial) Higher of the left ankle systolic pressure (dorsalis pedis or posterior tibial ) Higher brachial systolic pressure (Left or right arm) Left ABI Higher brachial systolic pressure (Left or right arm)
Sig. ra Maria ABI =0.83 ABI =0.90-1.30 NORMAL VALUE
ABI < 0.90 = Haemodynamicallysignificantarterialstenosis = PeripheralArterialDisease
As the 85% of PAD is determined by ATHEROSCLEROSIS ABI < 0.90 = ATHEROSCLEROSIS
Sig. ra Maria Rischio Cuore ISS <10% + ABI = 0.83 = Asymptomatic PAD = Subclinical ATHEROSCLEROSIS

Algorithm for use of the ABI in the assessment of systemic risk in the population Primary prevention: No antiplatelet therapy LDL <3.37 mmol/L (<130 mg/dL) except in diabetes where the LDL goal is <2.59 mmol/L (<100 mg/dL) even in the absence of CVD (cardiovascular disease); appropriate blood pressure (<140/90 mmHg and <130/80 mmHg in diabetes/renal insufficiency) Secondary prevention: Antiplatelet therapy LDL <2.59 mmol/L (<100 mg/dL) (<1.81 mmol/L [<70 mg/dL] in high risk); blood pressure <140/90 mmHg and <130/80 mmHg in diabetes/renal insufficiency. In diabetes, HbA1c <7.0%. L. Norgren et al TASC 2007
