WebDec 8, 2008 · The hypothesis—restoration of capillary perfusion and adequate collateral flow results in smaller infarct size and better clinical outcome, whereas lack of reperfusion coupled with poor collateral flow results in larger infarct and worse clinical outcome ( Figure 2 )—remains to be definitively validated. WebNov 1, 1995 · The percentage of perfused capillaries was determined by subsequent perfusion with an india ink solution (see “Solutions”), as previously described. 17 Briefly, immediately after the 60-minute reperfusion period, hearts were perfused with the ink solution at a pressure of 80 mm Hg for 1.5 minutes. WebThe incidence of the no-reflow (NR) phenomenon varies depending on the diagnostic criteria used. If just the angiographic criteria are considered (i.e., a degree of thrombolysis in myocardial infarction ≤2), it will be found that the incidence of NR is quite low; on the other hand, when the myocardial NR is taken into account (i.e., a decrease in the quality … dyson sphere program cell point
