Changes in Myocardial Perfusion Correlate With Deterioration of Left Ventricular Systolic Function in Chronic Chagas` Cardiomyopathy
(ELSEVIER SCIENCE INC, 2009)
OBJECTIVES This study aimed at analyzing the association between myocardial perfusion changes and the progression of left ventricular systolic dysfunction in patients with chronic Chagas` cardiomyopathy (CCC). BACKGROUND ...
Cintigrafía de ventilación y perfusión en el manejo del tromboembolismo pulmonar
(Sociedad Médica de Santiago, 2000)
A influência da perfusão cardíaca nas relações pressão/volume do ventrículo esquerdo.
(1993-12-01)
PURPOSE--To analyze the influence of the myocardial engorgement due to coronary perfusion on the left ventricular diastolic pressure/volume (P/V) relations. METHODS--The study was undertaken in the isovolumic blood-perfused ...
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.
Reactivity of the isolated perfused rat tail vascular bed
(1997-07)
Isolated segments of the perfused rat tail artery display a high basal tone when compared to other isolated arteries such as the mesenteric and are suitable for the assay of vasopressor agents. However, the perfusion of ...
Intercambio gaseoso y relación ventilación perfusión en el mal de montaña crónico
(Acta Andina, 1992)
Los hallazgos cada vez más frecuentes del mal de montaña crónico en personas jóvenes, de menos de 30 años, hipoxémicos, aunque moderadamente hipercápnicos, nos inducen a investigar más profundamente esta enfermedad y revisar ...
Do We Need a New Prescription to View Myocardial Perfusion?
(ElsevierNew York, 2012)
FUNCTIONAL AND ULTRASTRUCTURAL EVALUATION OF MYOCARDIAL PROTECTION PROVIDED BY INTERMITTENT CORONARY SINUS PERFUSION IN THE ISOLATED DOG HEART
(Associação Brasileira de Divulgação Científica (ABRADIC), 1991-01-01)
1. The protection offered by intermittent perfusion of of cardioplegic solution through the coronary sinus was investigated in isovolumic blood-perfused dog heart preparations submitted to 60 min of ischemia and 45 min of ...
