Abstract
Abstract Background Primary percutaneous coronary intervention (PPCI) restores myocardial tissue perfusion successfully in over 90 % of ST-elevation myocardial infarction (STEMI) patients .However there remains a small proportion of patients who exhibit no-reflow.(1) Empagliflozin is a sodium glucose co-transporter 2 (SGLT2) inhibitor that acts as a powerful anti-oxidant and has beneficial effects on endothelial function and reducing burden of ischemia in-vitro.(2) Aim and Objectives: To Assess the effect of Empagliflozin preloading in non-diabetic STEMI patients before PPCI on procedural, in-hospital outcomes and short-term Major Adverse Cardiovascular events (MACE) in a single tertiary center. Patients and Methods: The study was carried out on 200 non-diabetic STEMI patients presenting to our university hospital within the first 8 hours of symptom onset. Patients were randomised into 2 groups , the intervention group received 10mg Empagliflozin before PPCI with the standard medical therapy while the control group received only the standard medical therapy. Patients were assessed for demographic data, risk factors, procedural outcomes, clinical and in-hospital outcomes, and short-term MACE up to 1 month. Results: Our study found a significant difference between the intervention and control groups regarding contrast volume with a mean of 131 ml in the intervention group and 144 ml in control group with a p value of 0.009, incidence of no-reflow with 34.5% in the control group and only 18.2% in the intervention group and a p value of 0.014 and myocardial blush grade (MBG) were 84.1% of the patients in intervention group had MBG III after PCI while only 65.5% of the patients in the control group showed the same results with a p value of 0.019. Also, there was a significant difference in St-segment resolution post PCI as 59.1% of patients in the intervention group had complete ST segment resolution and only 39.1% of the patients in the control group had complete resolution with a p-value of 0.027, and total MACE in the first month which affected 44.8% of the patients in the control group and only 28.4% of those in the intervention group with a p-value of 0.024. Conclusion Our study showed that pre-loading of STEMI patients with Empagliflozin resulted in improvement in procedural outcomes, decreasing the incidence of coronary no-reflow, improvement in patient’s course during hospital stay and short-term MACE. Improvement in MACE was mainly due to reduced HF hospitalisations and anginal symptoms.
