Suppression of sympathetic nervous function in low-renin essential hypertension.
Study of general haemodynamics in 15 patients with low-renin essential hypertension showed haemodynamic and pathophysiological heterogeneity. However, there was suppression of sympathetic nervous system function in all low-renin patients, regardless of haemodynamic pattern. Subnormal sympathetic nervous activity was manifested by a low normal mean plasma-noradrenaline concentration at rest, dim...

متن کاملSympathetic Nervous Activation and Failure
Background Although heart rate variability (HRV) at 0.1 Hz has been proposed as a noninvasive clinical measure of cardiac sympathetic nerve firing, this premise has not been sufficiently validated by comparison with techniques such as microneurography and the measurement of norepinephrine spillover from the heart that more directly reflect presynaptic sympathetic activity. Methods and Results W...
متن کاملSympathetic nervous activation in essential hypertension: commonly neglected as a therapeutic target, usually ignored as a drug side effect.
Inappropriate and excessive activation of the sympathetic nervous system has been invoked as a cause of coronary heart disease. This pathophysiological linkage can take 2 forms. The most direct and explicit is when acute sympathetic nervous activation triggers adverse cardiac events (myocardial infarction, atrial fibrillation, ventricular arrhythmias, and Takotsubo cardiomyopathy have all been ...
متن کاملNeural sympathetic activity in essential hypertension.
Neural Sympathetic Activity in Essential Hypertension To the Editor: We read with great interest the article by Schlaich et al1 dealing with the issue of sympathetic augmentation in hypertension. In 1993, we demonstrated that neural sympathetic activity predominance is registered in essential hypertensive patients.2 These findings were supported by the overwhelming circulating noradrenaline (NA...
