Left ventricular afterload reduction is essential to decrease the trans-se ptal pressure gradient and thus decrease shunt volume, making a larger proportion of the blood flow from the left ventricle through the aortic valve. Older patients and those with poor right ventricular function often fall into this group.

50% of LAD STEMI have Q-waves by one hour. Smith : In limb leads, the ST vector is towards lead II (STE lead II STE lead III, which is more likely with pericarditis than with STEMI). Larger shunt volume means less blood exiting the left ventricle through the aortic valve and lower cardiac output. See Raitt et al.:
