Ischemic mitral regurgitation (IMR) as a result of myocardial infarction (MI) has been shown to be an extremely powerful independent predictor of heart failure and death. Although increasing IMR severity has been shown to be significantly associated with increasing mortality, significant left ventricular (LV) dilation, systolic dysfunction, and myocardial scar burden likely contribute to the pr...

This study was aimed to evaluate the image quality and lacunar lesion detection of thin-slice brain computed tomography (CT) images with different reconstruction algorithms, including filtered back projection (FBP), hybrid iterative reconstruction (HIR), and iterative model reconstruction (IMR) by comparison of routine slice images with FBP reconstruction. Sixty-one patients underwent noncontra...

The purpose of this study was to compare the image noise-reducing abilities of iterative model reconstruction (IMR) with those of traditional filtered back projection (FBP) and statistical iterative reconstruction (IR) in abdominal computed tomography (CT) imagesThis institutional review board-approved retrospective study enrolled 103 patients; informed consent was waived. Urinary bladder (n = ...

BACKGROUND The aim of this study is to determine the prognostic value of invasively assessing coronary physiology early after heart transplantation. METHODS AND RESULTS Seventy-four cardiac transplant recipients had fractional flow reserve, coronary flow reserve, index of microcirculatory resistance (IMR), and intravascular ultrasound performed down the left anterior descending coronary arter...

OBJECTIVES To study the variations in infant mortality rate (IMR) across Colombia's 33 administrative departments over the period 2003-2009, examine persistency of variations across departments over time, and relate those variations to the impact of socio-economic conditions and availability of care on IMR. MATERIALS AND METHODS Using vital statistics and related socio-economic data we establ...

Ischemic mitral regurgitation (IMR) is a term used to denote MR (mitral regurgitation) that occurs secondary to ischemic heart disease. Although transient ischemia can provoke IMR that is reversible with relief of ischemia, the most common form of IMR in clinical practice is associated with chronic ischemic cardiomyopathy. In such patients, global or regional left ventricular (LV) remodeling le...

BACKGROUND Ring annuloplasty, the standard treatment for ischemic mitral regurgitation (IMR), abolishes normal annular dynamics and freezes the posterior leaflet. We examined the impact of Paneth suture annuloplasty during acute IMR on motion of the mitral annulus and leaflets in an ovine model. METHODS AND RESULTS Eight sheep had radiopaque markers placed on the left ventricle, anterior mitr...

BACKGROUND Infant mortality rate (IMR) and neonatal mortality rate (NMR) are accepted as good indicators to measure the health status of a nation. This report describes recent declines in IMR and NMR in Turkey. METHODS Data on infants who died before 12 months of life were obtained from the Infant Mortality Monitoring System of Ministry of Health of Turkey between 2007 and 2012. A total of 94...

OBJECTIVES We examined how changes in demographic, geographic, and childbearing risk factors were related to changes in the Black-White infant mortality rate (IMR) gap over 2 decades. METHODS Using 1983-2004 Vital Statistics, we applied inverse probability weighting methods to examine the relationship between risk factors and 3 outcomes: the overall IMR gap, its birth weight component, and it...
