True/ False: CAD is most common Heart Disease in the heart.
True
Clinical presentation of CAD includes:
Stable angina, Unstable angina, MI,
Ischemic cardiomyopathy, CHF, SCD
Coronary Occlusion results in ______ dysfunction.
Diastolic
Most commonly identified CAD abnormality identified is
Abnormal MV inflow
If coronary obstruction persists for a threshold period of time _______myocardial necrosis and persistent wall motion abnormalities develop. (irreversible myocardial necrosis).
(>4 hours)
Severity of WMA depends on if _____ vs _______ infarction
transmural vs non-transmural infarction
_______ Myocardium occurs with transient occlusion of ____-____ minutes
Stunned myocardium, 20-60 mins
Typically with brief occlusion of 5 minutes- restores _______ seconds
Occlusion of 30-60 minutes- restoring function may take ______ hours
*6-120s
*24-72hrs
Around ____ weeks, necrotic myocardium is replaced by fibrosis and scar
6 weeks,
Regional dilation in area of the scar can result in _________ _________.
ventricular aneurysm. ( is defined as regional area of akinesis or dyskinesis and scar that has abnormal geometry in both diastole and systole)
Although the location of the WMA is an accurate marker for the site of ischemia or infarctions, the size of the WMA may be over or underestimated due to __________.
tethering (Tethering refers to the impact that an abnormal segment has on normal adjacent segments, a WMA will be overestimated by ~ 15% due to this)
What is Kawasaki Disease.
Is an infectious/inflammatory disease found in childhood. Major manifestation are rash and fever and associated with aneurysms of coronary arteries.
_______ is gold standard to assess origin and course of coronary arteries
CTA
what are the Global parameters of LV function>
Ventricular geometry
Ejection fraction
LV Volumes
Diastole and systole
Most commonly used assessment of LV systolic function is ______.
Most commonly used method for quantitation of LV volume is ______.
*EF
*Simpson rule
Write down from normal to aneurysmal wall motion.
1 for normal contraction or hyperkinesia, *2 for hypokinesis
3 for akinesia, *4 for dyskinesia. *5 for aneurysmal segments
