Ventricular function in cardiac-denervated and cardiac-sympathectomized conscious dogs.
The role of the autonomic nervous system in ventricular function was studied in conscious animals when either the cardiac nerves or the sympathetic nerves to the heart had been eliminated. Regional neural ablation was used to denervate the heart, and blockade of the cardiac sympathetic nerves was performed with propranolol. A reduction in the plateau of the ventricular output was seen in the ca...
متن کاملCardiac Denervation in Conscious Dogs
The time course of left ventricular (LV) function was compared in normal (N) and cardiac-denervated (CD) dogs over an 8-week period after instrumentation with solid-state LV pressure gauges and three pairs of ultrasonic crystals to measure LV long and short axes and wall thickness. Baseline LV systolic, end-systolic, and end-diastolic pressures did not differ in N and CD dogs. Heart rate was hi...
متن کاملVentricular Function in Conscious Dogs
Background. Prior studies in experimental canine models have demonstrated that intravenous cocaine administration causes myocardial depression. The purpose of the present study was to establish the mechanisms of cocaine's actions on myocardial and left ventricular performance after single intravenous bolus doses in conscious, chronically instrumented dogs, in which the full autonomic influences...
متن کاملImprovement of cardiac function by a cardiac Myosin activator in conscious dogs with systolic heart failure.
BACKGROUND Therapy for chronic systolic heart failure (sHF) has improved over the past 2 decades, but the armamentarium of drugs is limited and consequently sHF remains a leading cause of death and disability. In this investigation, we examined the effects of a novel cardiac myosin activator, omecamtiv mecarbil (formerly CK-1827452) in 2 different models of heart failure. METHODS AND RESULTS ...
متن کاملReduced subendocardial ryanodine receptors and consequent effects on cardiac function in conscious dogs with left ventricular hypertrophy.
The goal of this study was to examine the transmural distribution of ryanodine receptors in left ventricular (LV) hypertrophy (LVH) and its in vivo consequences. Dogs were chronically instrumented with an LV pressure gauge, ultrasonic crystals for measurement of LV internal diameter and wall thickness, and a left circumflex coronary blood flow velocity transducer. Severe LVH was induced by chro...
