Systems Behavior, Feed-back Loops, and High Blood Pressure Research

Systems behavior, feed-back loops, and high blood pressure research.

• In spite of the fact that much is known regarding various factors which determine blood pressure, the mechanism (s) responsible for hypertension remain elusive. The mystery applies not only to essential hypertension, but also to renal and, indeed, even to the hyper-tension associated with coarctation, adrenal tumors, and elevated intraeranial pressure. Almost characteristically, investigators...

HIGH PRESSURE BEHAVIOR OF KCl: STRUCTURAL AND ELECTRONIC PROPERTIES

The high pressure behavior of the structural and electronic properties of KC1 is studied with use of the density functional pseudopotential method within local-density approximation. Atzero pressure, the rocksalt phase is found to be lower in energy than CsCl structure. However, we predict a phase transition into CsCI structure at a pressure of about 1.5 GPa. The calculated ground state pro...

High Blood Pressure, FBS and LDL-C among Diabetic Iranians

Introduction: Control of blood pressure, fasting plasma sugar (FPS) and low-density lipoprotein-cholesterol (LDL-C) reduces to vascular complications of diabetes. In this study we determined the prevalence of diabetic individuals with uncontrolled blood pressure, FPS and LDL-C. Materials and Methods: We used data from three national Surveys of Risk Factors of Non-Communicable Disease (SuRFNCD) ...

Behavior Changes and the Prevention of High Blood Pressure

Pressure-Volume Loops in Clinical Research∗

Left ventricular ejection fraction (EF) depends on ventricular contractility, afterload, and preload. Preload is related to end-diastolic volume (EDV) and pressure; the relationship between these 2 parameters (the end-diastolic pressurevolume relationship, EDPVR) indexes the degree of ventricular remodeling. Although EF is known to correlate with mortality in the subset of heart failure patient...
