Coronary Flow Reserve and Myocardial Resistance Reserve Changes After Transcatheter Aortic Valve Implantation in Aortic Stenosis.

Aortic valve stenosis (AS) induces an alteration in hemodynamic conditions that are responsible for coronary microvasculature impairment. Relief of AS by transcatheter aortic valve implantation (TAVI) is expected to improve the coronary artery hemodynamic. We aimed to assess the midterm effects of TAVI in coronary flow reserve (CFR) and myocardial resistance reserve (MRR) by a continuous intracoronary thermodilution technique.

Ratio of Acceleration Time to Ejection Time for Assessing Aortic Stenosis Severity.

Background: Inconsistencies in the grading of aortic valve stenosis are frequent (24-38%). Guidelines highlight the waveform shape when discrepancies are present. Our aim was to evaluate the severity of aortic stenosis by the ratio of acceleration time to ejection time (AT/ET).

A home-based treadmill training reduced epicardial and abdominal fat in postmenopausal women with metabolic syndrome.

Introduction: The current study was designed to determine the effect of home-based treadmill training on epicardial and abdominal adipose tissue in postmenopausal women with metabolic syndrome (MS). A secondary objective was to identify significant correlations between imaging and conventional anthropometric parameters.

Material And Methods: Sixty postmenopausal women with MS volunteered for the current trial.

A comparative study of biomarkers for risk prediction in acute coronary syndrome-Results of the SIESTA (Systemic Inflammation Evaluation in non-ST-elevation Acute coronary syndrome) study.

Objective: We compared the 1-year predictive value of several inflammatory and non-inflammatory biomarkers in ACS patients.

Methods: In 610 patients (73.0% male)--36.

Elevated serum neopterin levels and adverse cardiac events at 6 months follow-up in Mediterranean patients with non-ST-segment elevation acute coronary syndrome.

Background: Little information exists regarding the prognostic role of biomarkers of inflammation in Mediterranean patients. High C-reactive protein and neopterin levels - a marker of macrophage activation - predict cardiovascular events in stable angina patients and patients with acute coronary syndromes (ACS). We sought to assess whether plasma neopterin levels predict adverse clinical outcomes in Mediterranean patients with non-ST elevation (NSTE) ACS, i.
