preventative medicine for thromboembolic events from acute arterial occlusion due to afib
anticoagulation- warfarin or factor x inhibitors
timeline of reinfarction post-MI
hours-2days
timeline of ventricular septal rupture post MI
hours-1 week
timeline of free wall rupture post MI
hours- 2 weeks
timeline of postinfarct angina post MI
hours- 1 month
timeline of papillary muscle rupture post MI
2 days-1 week
timeline of pericarditis post MI
acute- days
dressler- weeks-months
timeline of LV aneurysm post MI
5 days-3 months
EKG of LV aneursym
persistent ST elevation
deep q waves
why does lV aneurysm occur post MI?
scarred fibrotic myocardium
is ferritin increased in acute liver dz?
yes!
what is most common arrhythmia responsible for sudden cardiac arrest in setting of acute MI? and what is the mechanism
v fib
mechanism: reentry
signs of pericarditis
volume overload- JVP, edema
Kussmaul’s sign
pericardial knock
pericarditis findings on CXR and central venous tracing
CXR: pericardial calcifications
central venous tracing: sharp x and y descents
kussmauls sign
lack of typical inspiratory decline in CVP
pericardial knock
early heart sound after S2
most common cause of pericarditis in US vs developing countries
US: idiopathic, viral
dev: TB
do you always treat hyperkalemia with calcium gluconate?
only if abnl EKG
when do signs of fat embolism occur after accident?
at least 12-24 hours after
how do nitrates relieve angina?
systemic vasodialtion –>
reduce preload and LV EDV– reduces O2 demand
what exam is this and what is testing: place steoscope over upper abdomen and rock patients hips back and forth
abdominal succussion splash
tests gastric outlet obstruction (retained material will create a splash sound)
management of acute mod-severe COPD exacerbation
supp O2
bronchodilators
systemic glucocorticoids
antibiotics
PCI is indicated when in setting of STEMI
within 12 hrs of symptoms onset
AND
within 90 min from first medical contact to device time at PCI facility
digoxin toxicity presentation
N/V, diarrhea, vision changes, arrhythmias
