The intervention was an escalated protocol of NE boluses starting at 20 \u00b5g. The primary outcome was the incidence of PRS. The secondary outcomes were arrhythmia, electrocardiographic (EKG) ischaemic changes, mean pulmonary pressure after reperfusion, 3-month survival and 1-year survival.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      PRS occurred in 28 (70%) cases [95% confidence interval (CI) 54% to 83%,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; 0.001], with a relative risk reduction of 0.22 when compared to our previous results (90%). Twelve cases developed transient EKG ischaemic changes. All EKG ischaemic changes returned to baseline after correction of hypotension. There was no significant arrhythmia or bradycardia (95% CI 0 to 0.9). After reperfusion, the mean pulmonary artery pressure was not significantly higher than the normal limit (20 mmHg) (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.88).
