Abstract
Background: In patients with ST-segment elevation myocardial infarction (STEMI), Primary percutaneous coronary intervention (PCI) is the preferred reperfusion therapy. Timely primary PCI is essential in improving the clinical outcomes of these patients. The aim of this study was to evaluate the factors affecting balloon delay in STEMI treated patients by primary PCI and its relationship with major adverse cardiac events (MACE).
Methods: This prospective observational study was conducted on 143 cases of STEMI patients, who had the inclusion criteria and were treated by primary PCI, after obtaining written consent in Imam Khomeini hospital in Ahvaz, between May 2019 to May 2020. All-time components from symptom onset to PCI treatment include symptom-to-balloon time or ischemic time, symptom-to-door time and door-to-balloon time calculated. The incidence of major adverse cardiovascular events (MACE) including decompensated heart failure (DHF), acute coronary syndrome (ACS), sudden cardiac death (SCD) and cerebrovascular accident (CVA) was evaluated during 12 months follow up after primary PCI. left ventricular ejection fraction (LVEF) changes were evaluated 3 months after primary PCI.
Results: The median symptom-to-door time was 200.5 minutes (IQR: 90-438.75 min), the median ischemic time was 406 minutes (IQR: 231-671 min), and most patients had an ischemic time ≥120 minutes (92.4%) and door-to-device time ≥90 minutes (64.3%). The most common delay for treatment was in the symptom-to-door time (76.9%) and then the decision for primary PCI to transfer to the cat lab (17.5%). Overall, 59 (41.3%) of the patients experienced MACE during 1-year of follow-up, including ACS (13.3%), DHF (22.4%), cardiac death (9.8%) and CVA (2.1%). The patients age (OR: 0.96, P=0.020), LVEF changes (OR: 1.123, P=0.005) and STEMI type (OR: 0.705; P=0.039) predicted in-hospital MACE, while the symptom-to-balloon time (P=0.607) and door-to-balloon time (P=0.347) were not associated with MACE.
Conclusion: None of the time intervals were associated with the occurrence of MACE in one-year follow-up, and most STEMI patients were admitted to the hospital with a long delay. Therefore, efforts to shorten the time of hospitalization admission can help improve the MACE in STEMI patients under primary PCI in our medical centers.

Abstract
Background: Diabetes mellitus is associated with an increased risk of cardiovascular disease. The effects of add-in Sodium-glucose cotransporter 2 (SGLT2) inhibitors to standard statin treatments in acute coronary syndrome (ACS) patients remains controversial. The effects of the empagliflozin treatment after percutaneous coronary intervention (PCI) on the lipid profile of patients with type 2 diabetes mellitus (T2DM) have not been investigated yet. This study aimed to evaluate the efficacy of empagliflozin administration on lipid profile in diabetic patients with ACS after PCI.
Methods: This randomized, double-blind, placebo-controlled trial study was conducted from March until December 2020 on type 2 diabetes patients who underwent PCI and were referred to the Golestan and Imam Khomeini Hospitals. 93 patients (56 males and 37 females, mean age of 56.55 years old) were included. The patients were randomly assigned into two groups of receiving empagliflozin (10 mg, once daily) or a matching placebo, in addition to standard therapies for 6 months. The changes in metabolic parameters including lipid profile before and 6 months after interventions were assessed.
Results: After treatment in placebo group the level of LDL-C (median 0.90 mg/dl to 0.82, P=0.008) and HDL-C (median 0.40 mg/dl to 0.35, P=0.090) were decreased, while in the empagliflozin group the levels of LDL-C (median 0.87 mg/dl to 0.96, P=0.875) and HDL-C (median 0.38 mg/dl to 0.48), P=0.007) increased. Treatment with Empagliflozin and placebo had no significant effect on changing the levels of total cholesterol, TG and eGFR (P>0.05). The weight loss and FBS reduction in the empagliflozin group were significantly higher than placebo (P=0.001 and P=0.048, respectively).
Conclusion: Our results showed that adding Empagliflozin to standard treatment compared with a placebo for 6 months significantly increased LDL-C and significantly increased HDL-C. Also, except for weight loss and FBS, Empagliflozin was not more effective in improving the metabolic parameters of diabetic patients after PCI compared with placebo, so it seems that the use of this drug in diabetic patients with ACS after PCI is not very cost-effective.
