Complement depletion and persistent hemodynamic-hematologic responses in protamine-heparin reactions
(Elsevier, 1988-09)
Hypotension, bradycardia, pulmonary artery hypertension, neutropenia, and thrombocytopenia have been suspected to be due to complement activation following protamine reversal of heparin. This investigation examined these ...
Comparison of static incubation versus physiologic perfusion techniques for quantitation of luminal release of prostacyclin and thromboxane in canine arteries and veins
(Elsevier, 1988-07)
Intraluminal release of 6-keto-PGF1[alpha] and TxB2 in ex vivo canine arteries and veins was assessed during five consecutive 15-min periods using static incubation and physiologic perfusion techniques. Arterial segments ...
Effects of chronic aminodarone therapy on ventricular tachycardia induced by programmed ventricular stimulation
(Elsevier, 1987-01)
Several studies have reported upon the inducibility of ventricular tachycardia (VT) with programmed ventricular stimulation (PVS) during chronic amiodarone therapy; however, few studies have systematically described and ...
Effects of high stimulation current on the induction of ventricular tachycardia
(Elsevier, 1985-07-01)
Programmed stimulation at 2 right ventricular sites with 1 to 3 extrastimuli was performed at current strengths of twice diastolic threshold (1.0 +/- 0.2 mA, mean +/- standard deviation) and 10 mA in 41 patients undergoing ...
Anticoagulant effects of protamine sulfate in a canine model,
(Elsevier, 1988-07)
Protamine sulfate is considered a weak anticoagulant, yet little is known concerning the mechanism of this effect or its relation to prior heparin exposure. This investigation defined the influence of increasing doses of ...
Long-term follow-up of patients with previous myocarditis using radionuclide ventriculography
(Springer-Verlag, 1985-03)
A prospective long-term follow-up study is reported of 18 of 19 patients who survived a bout of presumed myocarditis 6–136 months (average 54 months) previously. The study included 14 males and four females, ranging from ...
Protamine reversal of anticoagulation achieved with a low molecular weight heparin. The effects on eicosanoids, clotting and complement factors
(Elsevier, 1987-10-01)
Hemodynamic and hematologic effects of protamine reversal of low molecular weight heparin (LMWH) anticoagulation with and without protamine pretreatment, as well as reversal of anticoagulation with unfractionated standard ...
R-wave amplitude changes during exercise in adolescents with left ventricular pressure and volume overload
(Elsevier, 1983-10-01)
To determine the diagnostic value of exerciseinduced R-wave changes in adolescents with congenital heart disease, the responses of 50 adolescents without significant heart disease were compared with those of 72 patients ...
