Final_Week2 Flashcards
Risk factors for angina pectoris
Male increased age HL HTN smoker DM obese
Treatment of STEMI
- MONA
- BB (not in cardiogenic shock, blocks, dec. CO)
- Reperfusion tx (30-60min. from arrival)
- PCI (90m from arrival)
- CABG
Treatment of UA/NSTEMI
Goal directed tx: decr. o2 demand, limit thrombus formation
- Bed rest, O2, analgesia, BB, CCB
- ASA, clopidogrel, prasugrel, or tricagrelor
- heparin
- thrombolytic therapy is NOT indicated
Heart failure classifications
Class I: Asymptomatic
Class II: Symptomatic with moderate activity
Class III: Symptomatic with mild activity
Class IV: Symptomatic at rest
Bioprosthetic valve
Lasts ~ 10 yrs, no LTAC, preferred for older
mechanical/bioprosthetic valve - anesthetic considerations
Biggest concern: anticoagulation
-assess valve function
MS - key points
- symptomatic: valve < 1.5cm2
- increased LA volume/pressure
- increased pulmonary venous pressure
MS - diagnosis
Echo - calculate valve area
-opening snap early in diastole
MS - Tx
- diuretics, BB, anticoag
- surgery: pHTN
MS - goal
avoid tachycardia (reduces SV)
MS - goal
avoid tachycardia (reduces SV) *full, slow, constricted
MR - goal
increased HR, decreased SVR
AS - key points
bicuspid valve (seen in younger pts) rheumatic dx, infective endocarditis -systolic murmur: mimics carotid bruit, RU sternal border -pulsus parvus -chest compressions: won't work
Critical AS
Valve area < 0.8 cm2
SAD: angina, syncope, DOE
AS - goal
prevention of HOTN/decreased CO
NSR 70-80
