OBJECTIVE To investigate the feasibility of coronary stenting in acute myocardial infarction. DESIGN Prospective observational study. PATIENTS 80 patients undergoing direct balloon angioplasty for acute myocardial infarction who had coronary Palmaz-Schatz stents implanted during a 3 year study period. Indications for stenting were abrupt reocclusion, large dissection with threatened reocclu...
BACKGROUND AND OBJECTIVES An elevated concentration of lipoprotein(a) {Lp(a)} is associated with an increased prevalence and increased severity of coronary artery disease. However, the relationship between Lp(a) levels and outcomes after acute myocardial infarction (AMI) is unclear. SUBJECTS AND METHODS Between October 2005 and June 2007, we measured serum Lp(a) levels in 832 consecutive AMI ...
Abstract Background Killip classification is a simple clinical tool for risk stratification in patients with acute myocardial infarction (AMI). However, predictors of high class at admission and its prognostic role non-obstructive coronary artery (MINOCA) are still poorly explored. Purpose To identify potential MINOCA compared to obstructive (MIOCA). Methods We included AMI undergoing angiogram...
AIMS We sought to assess the relative contribution of heart failure (HF) on admission for an acute myocardial infarction (MI) to the subsequent in-hospital stroke risk. METHODS AND RESULTS The VALsartan In Acute myocardial iNfarcTion (VALIANT) registry enrolled 5573 consecutive MI patients at 84 international sites from 1999 to 2001. We calculated odds ratios (ORs) for stroke and adjusted for...
We consider the focusing energy-critical nonlinear Schrödinger equation iut + ∆u = −|u| 4 d−2 u in dimensions d ≥ 5. We prove that if a maximal-lifespan solution u: I×Rd → C obeys supt∈I ‖∇u(t)‖2 < ‖∇W‖2, then it is global and scatters both forward and backward in time. Here W denotes the ground state, which is a stationary solution of the equation. In particular, if a solution has both energy ...
BACKGROUND There remains significant debate as to the relationship between fragmented QRS (fQRS) complexes on electrocardiogram (ECG) and acute myocardial infarction (AMI). Few studies have reported on this relationship in non-ST elevated AMI (NSTEMI), and thus, we attempt to assess this relationship and its potential short-term prognostic value. METHODS This was a single-center, observationa...
BACKGROUND/AIMS The aim of this study was to evaluate the impact of diabetes mellitus (DM) on in-hospital and 1-year mortality in patients who suffered acute myocardial infarction (AMI) and underwent successful percutaneous coronary intervention (PCI). METHODS Among 5,074 consecutive patients from the Korea AMI Registry with successful revascularization between November 2005 and June 2007, 1,...
BACKGROUND AND OBJECTIVES The purpose of this study is to identify the prevalence of progressive dilation in patients with acute myocardial infarction (AMI) combined with heart failure (HF) and determine the prognostic significance and associated factors with a geometric change of an infarcted heart. SUBJECTS AND METHODS A total of 1310 AMI patients with HF (63.9±12.5 years, 70% male) between...
BACKGROUND The impact of body mass index (BMI) on outcomes after primary percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI) remains unclear. METHODS AND RESULTS A total of 3,076 patients undergoing PCI for AMI within 48 h after symptom onset were studied. Patients were divided into 4 groups according to baseline BMI: lean (<20 kg/m(2)), normal weight (20.0-24.9 kg/...
