Cardiovascular Flashcards
standard first line initial testing for CAD
Exercise tolerance test (exercise stress test)
how is exercise tolerance test conducted
patient connected to 12 lead EKG and continuously monitored during exercise
primary goal of exercise stress test
increase workload incrementally to induce ischemia / until predetermined workload reached; used to detect CAD (seen as ischemic changes on EKG)
factors that decrease exercise stress test sensitivity
prior MI
resting BBB
conduction abnormality
pacemaker
inability to exercise / effort dependent
meds: beta blockers, digoxin
contraindications for exercise stress test
-previous MI (past two days)
-uncontrolled dysrhythmias
-decompensated HF
-endocarditis
-high grade heart block
-persistent stable angina
-hemodynamically significant aortic stenosis
what is a fusiform aneurysm
symmetric weakness of the entire circumference of the aorta that produces a bulge
what is a saccular aneurysm
asymmetric weakness or bleb on the side of the aorta - result from trauma or internal war defect caused by ulcer
what is a pseudo aneurysm
enlargement of only outer layer of the blood vessel wall; “false” aneurysm
classic diagnostic triad of AAA
hypotension
pulsatile abdominal mass and abdominal/back pain
ACC/AHA recommended screening for AAA
-Men 60+ with first degree relative w/ AAA
-Men 65-75+ that have ever smoked
*need PE and US to rule out AAA
Indications for ordering carotid US
Serial surveillance of known stenosis (>20%)
Vascular assessment in patient with multiple risk factors
Stroke assessment in patient with symptomatic CAD or PAD
Amaurosis fugax or Hollenhorst plaques seen on retinal exam
Hemispheric TIA
Stroke in candidate for carotid revascularization
Surveillance after carotid revascularization procedure (ex: endarterectomy)
Intraoperative monitoring during endarterectomy
symptoms indicative of end organ damage HTN
-loss of visual acuity
-severe HA
-confusion
-claudication
-chest pain
-dyspnea
-palpitations
-syncope
-hematuria
-oliguria
ACC/AHA stage 1 vs stage 2 htn dx
stage 1: 130-139/80-89
stage 2: >140/>90
*average 2+ readings on 2+ occasions for dx; home readings best if possible
ACC/AHA goal BP
130/80
labs/studies to obtain for HTN dx
-urine albumin to cr ratio
-CBC w/ diff
-Fasting blood glucose
-BMP
-fasting lipids
-EKG
*TSH if indicated
*24 h urine cortisol if Cushings suspected
