Renal Venous Pattern: A New Parameter for Predicting Prognosis in Heart Failure Outpatients

Genetic Polymorphism G894T and the Prognosis of Heart Failure Outpatients

BACKGROUND Previous studies have analyzed the role of the genetic polymorphism of endothelial nitric oxide synthase on heart failure prognosis. However, there are no studies relating the G894T and heart failure in Brazil. OBJECTIVE To evaluate the association between G894T GP and the prognosis of a sample of Brazilian outpatients with heart failure. METHODS Cohort study included 145 patient...

A New Minimum Order Lumped-Parameter Model of Circulatory System for Patients with Suffered Left and Right-Sided Heart Failure

In this study a new minimum lumped electrical model of total circulatory system through numerical solutions to approximate the response of the human circulatory system was presented. Among five existent ventricular elastances as activity function of heart pumps, a more accurate model was chosen as well as the operation of baroreflex system to accommodate variations in heart rate and systemic va...

Advances in Heart Failure Venous Thromboembolism in Hospitalized Patients With Heart Failure Incidence, Prognosis, and Prevention

Heart failure (HF) is a common cardiovascular cause of hospitalizations in the United States and the most frequent reason among patients aged 65 years and older.1 A recent report by the National Hospital Discharge Survey showed an increase in the number of hospital admissions with a diagnosis of HF from 1.3 million in 1979 to 3.9 million in 2004, with 30% to 35% of these carrying a primary diag...

A New Method for Predicting Well Pattern Connectivity in a Continental Fluvial-delta Reservoir

The features of bad flow unit continuity and multiple layers emphesize the importance of a well pattern design for the development of a fluvial-delta reservoir. It is proposed a method to predict well pattern connectivity (WPC) based on the exploration and evaluation of wells. Moreover, the method helps evaluate the risk of well placement. This study initially establishes the parameters for cha...
