Abstract:
The haemodynamic indices proposed by Buckberg et al. have been used to evaluate total coronary flow and its distribution to the subendocardial tissue. The following conclusions were drawn from the data obtained in humans and in experimental pathology: 1) in regional ischaemia (angina, myocardial infarction), the DPTI/TTI ratio expresses the degree of subendocardial hypoperfusion with fair approximation, although it has some theoretical limitations, 2) in total myocardial ischaemia, as occurs during ECC, the index provides an accurate picture of the subendocardium and a useful idea of the real effectiveness of the means of myocardial protection.

Antianginal Drugs: Nitrates and β-Blockers
Organic nitrates, such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow. Administered...
