Submit Manuscript | http://medcraveonline.com 8]. The concept of shock index, defined as the ratio of heart rate and systolic blood pressure, first introduced by Allgower et al, in 1967 as a simple and effective means for gauging the degree of hypovolemia in hemorrhagic and infectious shock states [9]. Subsequently, experimental and clinical studies demonstrated that SI was inversely related to physiologic parameters, such as cardiac index, stroke volume, left ventricular stroke work, and mean arterial pressure [10].

No-Reflow Phenomenon in Patients with ST-Elevation Acute Myocardial Infarction, Treated with Primary Percutaneous Coronary Intervention: A Study of Predictive Factors
Introduction: No-reflow phenomenon in coronary vessels, manifested in some patients with reperfused acute myocardial infarction (MI), is associated with poor clinical and functional outcomes. Therefore, evaluation of predisposing risk factors can be helpful in risk assessment and identification of patients at higher risk. Herein, we aimed to study the predictive factors for the development of...

Introduction: No-reflow increases the complications and mortality rate of primary percutaneous coronary intervention (PCI). Therefore, it is important to identify patients at a higher risk of developing no-reflow. This study aimed to systematically review the prognostic value of the platelet-to-lymphocyte ratio (PLR) to predict no-reflow. Materials and Methods:</s...
متن کاملComparison of in-Hospital Outcome after Percutaneous Coronary Intervention Between Patients with Anterior Myocardial Infarction and Those With or Without Ramus Intermedius
Introduction: Primary percutaneous coronary intervention (PPCI) is used for the treatment of ST segment elevation myocardial infarction (STEMI). Anterior STEMI is associated with adverse outcomes, and it is possible that the presence of ramus intermedius (RI) would inversely affect the outcome. This research involved the evaluation of the influence of RI presence on clinical ou...

Background and Objective: Acute myocardial infarction (MI) is caused due to coronary artery occlusion and divided into two forms of ST-elevation (STEMI) and non-ST-elevation (NSTEMI) myocardial infarction. This study aimed to determine the success rate of treatment with primary PCI (percutaneous coronary intervention) versus thrombolysis in the establishment of perfusion and to evaluate the sho...
