Porcine Valve Bioprosthesis: a Legacy from Mario Vrandecic
Resumo – Pontos Essenciais O termo disautonomia abrange um conjunto de condi ções clínicas com características e prognósticos distintos. Classificam-se em síndromes reflexas, síndrome postural ortostática taquicardizante (SPOT), síndrome da fadiga crônica, Hipotensão Ortostática Neurogênica (HON) e a Síndrome da hipersensibilidade do seio carotídeo. As síndro mes reflexas (vasovagal) não serão discutidas neste artigo. As síndromes reflexas (vasovagal) são, na maioria das vezes, benignas, e ocorrem usualmente em pacientes sem doença intrínseca do sistema nervoso autônomo (SNA) ou do coração. P...

Cardiovascular Disease Prevention in Adolescence: New Possibilities
Conclusion: In adolescents, obesity was associates with MetS and caused endothelial dysfunction. Increased WC and SBP could be involved in this alteration.

The Importance of Post-Infarction Exercise Programs
Conclusion: Small-sized MI changes cardiac structure and LV systolic function. Late aerobic exercise is able to improve functional capacity and cardiac remodeling by preserving the left ventricular geometry. NADPH oxidase subunits gene expression is not involved in cardiac remodeling or modulated by aerobic exercise in rats with small-sized MI. (Source: Arquivos Brasileiros de Cardiologia)

Cardiovascular Risk Factors in Cardiologists Certified by the Brazilian Society of Cardiology: Lessons to be Learned
Conclusions: The Brazilian cardiologists participating in the study had a high prevalence of SAH, DM and DLP, but only a half of participants were aware of these conditions and, among these, the rates o f controlled disease were low for SAH and DLP, although cardiologists are professionals with great knowledge about these CVRF. These findings represent a warning sign for the approach of CVRF in Brazilian cardiologists and encourage the conduction of future studies. (Source: Arquivos Brasileiros de Cardiologia)
