Abstract
Aim and objectives: The aim of this study was to assess the impact of high intensity statins used prior to primary PCI in patients presenting with acute STEMI (ST-elevation Myocardial Infarction) on myocardial perfusion and in-hospital MACE (major adverse cardiac events). Patients and Methods: The study included 170 patients who presented with acute STEMI to the cardiology department of Ain Shams university hospitals and underwent primary PCI (percutaneous coronary intervention). They were divided into two groups where the first group received high intensity statins (40- 80mg of atorvastatin or 20-40mg of rosuvastatin) besides guideline recommended therapy before primary PCI and the 2nd group served as a control group and received guideline recommended therapy, and high intensity statins after going back to the coronary care unit after primary PCI. Post interventional thrombolysis in myocardial infarction (TIMI) flow grade and myocardial blush grade (MBG) were recorded and ST-segment resolution was measured. Results: The majority of patients in both groups had the LAD as the culprit vessel for their presentation. In the control group there were 4 patients with TIMI I flow and MBG I, 13 with TIMI II flow and MBG II and 68 with TIMI III flow and MBG III. Meanwhile in the cases group there was 1 patient with TIMI I flow and MBG I, 3 with TIMI II flow and MBG II and 81 with TIMI III flow and MBG III. This difference was statistically significant with a P value of 0.010. There were 34 patients in the cases group who showed complete ST-segment resolution (40%) vs 19 patients (22.4%) in the control group which was statistically significant with a P value of 0.013. In addition, ejection fraction measured by M-mode had values of Mean+-SD of 45.91 ± 5.49 in cases group vs 43.01 ± 8.80 in control group which was statistically significant with a P value of 0.011. There was not a statistically significant difference between the two groups regarding in-hospital death of all causes and stroke after primary PCI. Conclusion: High intensity statin loading before primary PCI resulted in improved post-procedural TIMI flow, MBG, complete ST-segment resolution and ejection fraction as measured by Mmode but did not decrease incidence of in-hospital MACE.
