Heart rate dynamics during a treadmill cardiopulmonary exercise test in optimized beta-blocked heart failure patients
(Faculdade de Medicina / USP, 2008)
BACKGROUND: Calculating the maximum heart rate for age is one method to characterize the maximum effort of an individual. Although this method is commonly used, little is known about heart rate dynamics in optimized ...
Coronary perfusion pressure as a determinant of ventricular performance
(1980-12-01)
The results observed in this work support the view that coronary perfusion pressure affects ventricular performance independently of metabolic effects; a mechanism operating in beat-to-beat regulation is proposed.

Proteção miocárdica ao coração hipertrofiado: O eterno desafio
(2008-01-01)
The myocardial protection allowed great advance in cardiac surgery, decreasing the mortality and making more feasible complex surgeries. Latterly, the patient population elected for cardiac procedures has been changing ...
