The index of microcirculatory resistance predicts myocardial infarction related to percutaneous coronary intervention.
BACKGROUND Periprocedural myocardial infarction (MI) occurs in a significant proportion of patients undergoing percutaneous coronary intervention (PCI) and portends poor outcomes. Currently, no clinically applicable method predicts periprocedural MI in the cardiac catheterization laboratory before it occurs. We hypothesized that impaired baseline coronary microcirculatory reserve, which reduces...
متن کاملIndex of Microcirculatory Resistance at the Time of Primary Percutaneous Coronary Intervention Predicts Early Cardiac Complications: Insights From the OxAMI (Oxford Study in Acute Myocardial Infarction) Cohort
BACKGROUND Early risk stratification after primary percutaneous coronary intervention (PPCI) for ST-segment-elevation myocardial infarction is currently challenging. Identification of a low-risk group may improve triage of patients to alternative clinical pathways and support early hospital discharge. Our aim was to assess whether the index of microcirculatory resistance (IMR) at the time of PP...
متن کاملEvaluation of ejection fraction in patients with acute myocardial infarction undergoing percutaneous coronary intervention
Introduction: Percutaneous coronary intervention (PCI) is a reperfusion strategy to increase life expectancy and ejection fraction (EF) in ST-segment elevation myocardial infarction (STEMI) patients. We investigated the effect of location, severity, type of lesion, number and type of vessel involved and time of angioplasty on the increase in EF in STEMI patients undergoing primary PCI (P-PCI) a...
متن کاملPrognostic value of the Index of Microcirculatory Resistance measured after primary percutaneous coronary intervention.
BACKGROUND Most methods for assessing microvascular function are not readily available in the cardiac catheterization laboratory. The aim of this study is to determine whether the Index of Microcirculatory Resistance (IMR), measured at the time of primary percutaneous coronary intervention, is predictive of death and rehospitalization for heart failure. METHODS AND RESULTS IMR was measured im...
متن کاملPercutaneous coronary intervention in acute myocardial infarction.
857 R of the infarct-related artery (IRA) by percutaneous coronary intervention (PCI) limits the size of the infarct and preserves left ventricular (LV) function. In the 1980s, various randomized trials using thrombolytics that enrolled thousands of patients with acute myocardial infarction with ST-elevation (STEMI) demonstrated the clear superiority of these agents over placebo in terms of maj...
