Abstract
Background: Remote ischemic preconditioning (RIPC) is a simple non-invasive method by using cycles of ischemia and reperfusion on a remote organ. 
Objective: To determine the effect of RIPC outcomes in patients with ST-segment-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI).
Methods: This double blind randomized clinical trial was conducted in two teaching and reference hospitals in Mashhad, Iran. Sixty patients with acute STEMI were enrolled from October 2018 to January 2019. The patients were allocated into two groups, by using sealed envelope randomization i.e., a study group of patients who had undergone RIPC intervention and a control group of patients who had not undergone RIPC. Half an hour before PPCI, a sphygmomanometer cuff was placed around the left upper arm and inflated up to 200mmHg for five minutes; then the cuff was deflated for another five minutes, and this cycle was repeated 3 times before or during PPCI. Corrected Thrombolysis in Myocardial Infarction (TIMI) frame count, ST-segment resolution, reperfusion arrhythmias and contrast induced nephropathy (CIN) were evaluated in both groups after PPCI. Study data was analyzed by SPSS version 16.
Results: A total number of 26 males and 14 females were studied in study groups (n=20 for each). Both groups were homogenous according to their baseline characteristics. Both TIMI grade and Corrected Thrombolysis in Myocardial Infarction Frame Count CTFC significantly improved after RIPC (p=0.001 and p<0.0001 respectively). Moreover, CIN and reperfusion arrhythmias were reduced in the intervention group (p=0.028 and p=0.016 respectively). Also, ST-segment resolution was significantly different among groups (p=0.002). After adjusting for baseline factors only a significant relationship was observed between performing intervention and final TIMI grade (OR=26.416, 95% CI for OR=1.063, 656.184, p=0.046). 
Conclusion: RIPC can effectively reduce CIN and reperfusion arrhythmias in patients undergoing PPCI. Also, RIPC improved ST segment resolution and TIMI flow grade, and corrected TIMI frame count. Based on our results, RIPC may have a protective effect of on PPCI outcomes.
Trial registration: The trial was registered at the Iranian Clinical Trial Registry (IRCT) (http://www.irct.ir) with the IRCT identification number IRCT20150614022713N2.
Founding: This research was supported financially by the Research Council of Mashhad University of Medical Sciences (Ref: 970162).

The worldwide spread of COVID-19 as an emerging, rapidly evolving situation, and the dramatic need of urgent medicine or vaccine, has rapidly brought new hypotheses for pathophysiology and potential medicinal agents to the fore. It is crucial that the research community provide a way to publish this research in a timely manner.

 

To contribute to this important public health discussion, the Electronic Physician Journal is excited to announce a fast-track procedure to help researchers publish their articles on COVID-19 related subjects that fall under the broad definition of public health, internal medicine, and pharmacology. We are especially welcome to all hypotheses about the pathological basis of the COVID-19 infection and the possible characteristics of potential medicine and vaccine. Submit your manuscript here
