The electron transport system transfers protons from the inner compartment to the outer; as the protons flow back to the inner compartment, the energy of their movement is used to add phosphate to ADP, forming ATP. Water flows across the respiratory surface of the gill in one direction while blood flows in the other direction through the blood vessels on the other side of the surface

Patients with prior evidence of an anaphylactoid reaction to contrast media should receive appropriate steroid and antihistamine prophylaxis before repeat contrast administration. (Level of Evidence: B) Patients who develop clinical restenosis after BMS should be treated with DES if anatomic factors are appropriate and the patient is able to comply with and tolerate DAPT (Dibra et al., 2007; Holmes et al., 2006; Kastrati et al., 2005)

Beyond survival, bypass surgery may be indicated to alleviate symptoms of angina above and beyond medical therapy or to reduce the incidence of nonfatal complications like MI, congestive heart failure, and hospitalization.

This is the first large-scale study of CAAs in which the denominator (all candidates at risk) was known, the setting of the clinical events was consistent (extreme physical training), and all the fatal events led to necropsy studies.18 In comparison, Drory and colleagues19 studied the incidence of CAAs in a continuous series of 162 patients with sudden unexpected death. In this view, the proximal course appears wider than the more distal vessel, and it originates next to the LCA (which is also ectopic), high above the left aortic sinus (LS)

In non-Q-wave MI, a clot may block the coronary artery for a period of time, and then break up by itself or collateral circulation may help to restore blood flow to the area of ischemia (lack of blood supply)
