Correlation Between Triglyceride Glucose Index and Residual SYNTAX Score in ST-elevation Myocardial Infarction Patients Undergoing Primary Percutaneous Coronary Intervention

Brief Summary

Detailed Description

ST-elevation myocardial infarction (STEMI) is known as a life-threatening complication of coronary artery disease (CAD) and it is one of the leading causes of death all over the world. Primary percutaneous coronary intervention (PPCI) of the culprit vessel in patients with STEMI is standard clinical practice . At the time of PPCI, 40-65% of the patients exhibit one or more concomitant coronary lesions (i.e., multivessel disease (MVD)). The presence of narrowed coronaries other than those related to index ischemia in patients with STEMI is suggested as a feature associated with adverse clinical outcomes . The recently developed residual SYNTAX Score (RSS) (developed 2012 and validated in 2013) is an objective, quantitative measure of the degree and complexity of residual stenosis after percutaneous coronary intervention (PCI) .It was developed to quantitatively assess the degree and complexity of residual stenoses, based on recalculating the SYNTAX score from coronary angiography after PCI . Higher RSS has been associated with worse outcome in patients undergoing angiography-mediated PCI . Insulin resistance (IR) is an important risk factor for the development of CAD . It is defined as a state in which a greater than normal amount of insulin is required to elicit a quantitatively normal response . Previous studies have shown an independent association between IR and CVD. IR is tightly associated with increased cardiovascular morbidity and mortality by adversely modifying well-established cardiovascular risk factors such as dyslipidemia and hypertension and by causing endothelial dysfunction .
