Preductal coarctation is associated with differential cyanosis and a stronger pulse in the right upper limb than the left.

X rays can show rib notching.

Rib Notching is associated more with the postductal due to the collateral circulation, also weak pulses in lower extremities
It is also present in the preductal coarctation (medessentials Kaplan p 255, FA p 268)

MI: usually affect LAD>RCA>Circumfliex,
the first evidence is visible after 12-24 hours (contraction bands)
ECG is the gold standard in the first 6 hours for diagnosis.
Troponin I rise after 4 hours and is elevated for 7-10 days
Transmural infarct will show ST elevation or pathologic Q waves
Subendocardial infarct ST depression on ECG

If the LAD is infarct it could affect the Anterior Wall or Anteroseptal we differentiate between them using Lead with Q waves
If the RCA is infarct it will affect the Inferior Wall

It increases with the Valsalva, and decreases with clenching your fist and leaning forward (the opposite of aortic stenosis). Septum is asymmetrical as well.
