BACKGROUND Ischemic mitral regurgitation (iMR) predisposes to right ventricular (RV) pressure and volume overload, providing a nidus for RV dysfunction (RVDYS) and non-ischemic fibrosis (NIF). Echocardiography (echo) is widely used to assess iMR, but performance of different indices as markers of RVDYS and NIF is unknown. METHODS iMR patients prospectively underwent echo and cardiac magnetic ...

BACKGROUND In patients with angina and nonobstructive coronary artery disease (NOCAD), confirming symptoms due to coronary microvascular dysfunction (CMD) remains challenging. Cardiac magnetic resonance (CMR) assesses myocardial perfusion with high spatial resolution and is widely used for diagnosing obstructive coronary artery disease (CAD). OBJECTIVES The goal of this study was to validate ...

OBJECTIVES This study investigated the relationship between the index of microcirculatory resistance (IMR) with myocardial injury and microvascular obstruction (MVO) assessed by contrast-enhanced cardiac magnetic resonance (ceCMR) imaging in a broad range of ST-segment elevation myocardial infarction (STEMI) patients undergoing emergency percutaneous coronary intervention (PCI). BACKGROUND Co...

pulling force is one of the most important variables in pultrusion process which determines the capacity of the pultrusion machine. one of the characteristics of a desired pultrusion process is a low pulling force and a high line speed.among the important factors affecting the pulling force are the internal mold release agent (imr) and the content and particle size of the filler in resin formul...

Objective This report presents 2002 period infant mortality statistics in Indiana from the linked birth/infant death data set (linked file) by race, a variety of infant and maternal characteristics, and leading causes of death. Methods The numerator for the 2002 period linked file consists of Indiana resident infant deaths (less than one year of age) occurring in 2002. In 2002, 99.2 percent of ...

Measurements of incubation energetics can vary depending on the method used to measure metabolism of an incubating bird. Therefore, we evaluated the energy expenditure of six male and four female wandering albatrosses (Diomedea exulans Linnaeus) using doubly labeled water (DLW), the rate of mass loss, and estimates of metabolic water production derived from water influx rate (WIR). Incubation m...

OBJECTIVE To analyze IMR evolution in the São Paulo Metropolitan Area (SPMA) between 1980 and 2000, in terms of spatial, age and, causal differences. METHODS SPMA municipalities were divided into 5 groups, based on their 1980 IMRs: 90 per thousand lb (Group 1); 70-89 per thousand lb (Group 2); 50-69 per thousand lb (Group 3); <50 per thousand lb (Group 4). Group 5 comprised the municipality o...

UNLABELLED The study deals with infant mortality (IMR) that is one of the most important aspects of indigenous vulnerability. BACKGROUND The Sami are one of very few indigenous peoples with an experience of a positive mortality transition. OBJECTIVE Using unique mortality data from the period 1750-1900 Sami and the colonizers in northern Sweden are compared in order to reveal an eventual in...

BACKGROUND Although surgical annuloplasty is the standard repair for ischemic mitral regurgitation (IMR), its application is limited by high morbidity and mortality. Using 2D and real-time 3D echocardiography in an ovine model of chronic IMR, we evaluated the geometric impact and short-term efficacy of a percutaneous transvenous catheter-based approach for mitral valve (MV) repair using a novel...
