--Risk: same as CAD, Hx in same sex close family, HTN, lipidemia, hard drinking water!!, "toxicity", diabetes, stress, menopause
--S/Sx: pressure/constriction, discomfort, chest, jaw, neck, L shoulder, arm, subscap
--S/Sx: incr HR, BP, diffuse apical pulse, mb S4 sound dt decr LV compliance
--Pathophysio: ischemia of heart muscle
--occurs at night, at risk-->unstable-->poss MI
--Dx: stress testing gives more false negatives in females
--types: variant/Prinzmetal's dt spasm, @ rest, ST elev not depress, same time ea day
--types: microvascular, "syndrome x", usu not seen on angiogram, typical sx
--types: silent ischemia: ASx CAD, most in diabetics, screen DM pts for CAD!!!
--PE: peripheral pulses, xanthomas, pt tenderness?->not CAD
--PE: EKG norm btw attacks
--EKG: during episodes see Q wave (small OK, big->prob) and T wave inversion, poss ST depression, small R wave

V FIB
--S/Sx: flip-flop/flutter in chest

VPB = Ventricular Premature Beat
--ECG: QRS complexes regular in groups, then early beat, wide QRS, inverted T, then back to normal QRS
-->increasing early beats to lower ratio of normal beats is worse-->V tach-->V Fib

MITRAL REGURGE
--most likely systolic murmur at PMI
--loud systolic murmur in 5th interspace @ L midclavicular line (PMI)
--more with age

MVP
--antibiotic prophylaxis for dental work is no longer recommended

--secondary usdt surgery, trauma, radiation, tumors, infx.
--mbdt chronic venous insuff
--COMPLIC: lymphangina

IDIOPATHIC TELANGIECTASIAS
-- = spider veins, don't confuse with varicose
--clinically insignificant (??!?)

VARICOSE VEINS
--S/Sx: ache, fatigue, heat, better w/ elev, itching, intermittent claudication
--PE: with pt standing, check for diabetic neuropathy, ulcertaions, investigate for hip, knee, lumbar issues, arthritis, check arterial sufficiency
--COMPLIC: edema, eczema, pigment, ulceration
--Tx: compression, wound care, surgery, exercise, elev, herbs for venous health

CHRONIC VENOUS INSUFFICIENCY and postphlebitic syndrome
--posphlebitic syn = venous damage after DVT, mb w/o signs
--ETIO: DVT, valve insuff, decr heart contract, venous HTN
--RISK: trauma, obesity, old age
--COMPLIC: edema, inflam, hypoxia
