Microvascular Dysfunction Is Associated With Impaired Myocardial Work in Obstru...

Background Two-dimensional speckle tracking echocardiography has been shown to correlate with microvascular dysfunction, a hallmark of hypertrophic cardiomyopathy (HCM). We hypothesized that there is an association between myocardial work and left ventricular ischemia, with incremental value to global longitudinal strain, in patients with HCM. Methods and Results We performed a prospective assessment of patient...

Associations Between Perfusion Defects, Tissue Changes and Myocardial Deformati...

Background: Microvascular dysfunction is an often overlooked feature of hypertrophic cardiomyopathy (HCM). Our aim was to assess the association between microvascular dysfunction, wall thickness, tissue characteristics and myocardial deformation in HCM patients, by analyzing individual myocardial segments. Methods: Prospective assessment including cardiac magnetic resonance to assess wall thickness, T1 and T2 m...

Blunted Coronary Flow Velocity Reserve is Associated With Impairment in Systoli...

Background Coronary microvascular dysfunction constitutes an important pathophysiological feature in hypertrophic cardiomyopathy (HCM). We aimed to assess the association between impaired coronary flow velocity reserve (CFVR) and ventricular systolic function and functional capacity. Methods Eighty-three patients with HCM were enrolled in this prospective cohort study. Patients underwent echocardiogram to evalu...

The Impact of Ischemia Assessed by Magnetic Resonance on Functional, Arrhythmic...

Aims: The aim of the study is to investigate the association between the degree of ischemia due to coronary microvascular dysfunction (CMD) and the left ventricular (LV) tissue characteristics, systolic performance, and clinical manifestations in hypertrophic cardiomyopathy (HCM). Methods and Results: This prospective study enrolled 75 patients with HCM without obstructive epicardial coronary artery disease. Ea...

The population impact of rheumatic and musculoskeletal diseases in relation to ...

The aim of this study was to quantify the population impact of rheumatic and musculoskeletal diseases (RMDs) with other non-communicable diseases (NCDs), using two complementary strategies: standard multivariate models based on global burden of disease (GBD)-defined groups vs. empirical mutually exclusive patterns of NCDs. We used cross-sectional data from the Portuguese Fourth National Health Survey (n = 23,75...

Biological aspects of Eriopis connexa (Germar) (Coleoptera: Coccinellidae) fed ...

Eriopis connexa (Germar) (Coleoptera: Coccinellidae) ocorre em vários países da América do Sul e sua criação massal é importante para programas de controle biológico. Este trabalho avaliou os aspectos biológicos de larvas de E. connexa alimentadas com ovos de Anagasta kuehniella (Zeller) (Lepidoptera: Pyralidae) e de Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) congelados por um dia, ovos fresco...

The death of Fernando Pessoa. The differential diagnosis of liver colic.

A clinical review of the most probable cause of death of the poet Fernando Pessoa is made. The many times cited final diagnosis of "hepatic colic" and the limited clinical information available are considered. The spectrum of chronic alcoholism and its risks are questioned by recent advances on pathology knowledge.; A clinical review of the most probable cause of death of the poet Fernando Pessoa is made. The m...
