OBJECTIVE Precise perioperative risk stratification is important in vascular surgery patients who are at high risk for major adverse cardiovascular events (MACE) peri- and postoperatively. In clinical practice, the patient's perioperative risk is predicted by various indicators, e.g. revised cardiac index (RCRI) or modifications thereof. Patients suffering from chronic kidney disease (CKD) are ...

BACKGROUND AND PURPOSE Prognosis after carotid endarterectomy is mainly determined by the occurrence of major adverse cardiovascular events (MACEs). Optimal medical treatment to reduce risk is the mainstay of MACE prevention. The level of risk of MACE may determine the initiation and aggressiveness of medical treatment, yet a prediction rule to assess that absolute MACE risk after carotid endar...

BACKGROUND Treatment of saphenous vein graft (SVG) stenosis with percutaneous coronary intervention has a 15% to 20% incidence of major adverse cardiac events (MACE) within 30 days. Although MACE rates are reduced significantly by the use of embolic protection devices (EPDs), neither the level of baseline risk nor the benefit provided by EPDs has been well characterized. METHODS AND RESULTS D...

Background and Aims: Bilirubin has been considered an antioxidant that protects against atherosclerosis. The aim of this study was to evaluate the relationship of serum bilirubin level with the severity and complexity of coronary artery disease (CAD) and long-term outcome in the patients undergoing primary percutaneous coronary intervention (PCI). Materials and Methods: This prospective coho...

The minimum average correlation energy (MACE) filter, which is linear and shift invariant, has been used extensively in the area of automatic target detection and recognition (ATD/R). We present a nonlinear extension of the MACE filter, based on a statistical formulation of the optimization criterion, of which the linear MACE filter is a special case. A method by which nonlinear topologies can ...

Poor health-related quality of life (HRQL) is associated with mortality in cardiac patients. Patients (N=667) with poor HRQL after percutaneous coronary intervention had a higher incidence of early (< or =6 months) major adverse cardiac events (MACE) than did patients with good HRQL, whereas there was no difference for late (>6 months) MACE over a 2-year follow-up period. Poor HRQL remained an ...

The minimum average correlation energy (MACE) filter of [Mahal, Ravi], produces sharp correlation peaks over the recognition class in pattern recognition problems. It is known that the MACE filter of [Mahal, Ravi] can be formulated as a pre-whitening filter cascaded with a linear synthetic discriminant function. It will be shown that the MACE filter is equivalent to a linear associative memory ...

OBJECTIVES To investigate whether intravascular ultrasound (IVUS) guided percutaneous coronary intervention (PCI) could improve clinical outcomes compared with angiography-guided PCI in the treatment of unprotected left main coronary artery stenosis (ULMCA) in the elderly. METHODS This controlled study was carried out between October 2009 and September 2012, in Qinhuangdao First Hospital, Heb...

AIM The aim of this paper was to investigate the value of Global Registry of Acute Coronary Events (GRACE) and thrombolysis in myocardial infarction (TIMI) risk scores for risk stratification and prognosis in female patients with non-ST segment elevation acute coronary syndrome (NSTE-ACS). METHODS Non-elderly (<65 years) and elderly (≥65 years) female patients with NSTE-ACS (totally 869 cases...

PURPOSE Few studies have reported on predicting prognosis using myocardial perfusion single-photon emission computed tomography (SPECT) during coronary artery disease (CAD) treatment. Therefore, we aimed to assess the clinical implications of myocardial perfusion SPECT during follow-up for CAD treatment. MATERIALS AND METHODS We enrolled 1153 patients who had abnormal results at index SPECT a...
