Journal Article Psychosom Med · 1998 OBJECTIVE: Prospective studies have demonstrated that anxiety predicts sudden cardiac death, but the mechanism underlying this increased risk is unclear. This study examined whether anxiety is associated with reductions in vagal control of heart rate in he ... Full text Link to item Cite

Blood pressure responses to mental stress in emotionally defensive patients with stable coronary artery disease.

Journal Article Am J Cardiol · August 1, 1997 Emotional defensiveness, defined by concealment of both negative emotions and personal vulnerability, was substantially and consistently correlated with the magnitude of blood pressure reactions to 2 types of mental stress among coronary patients, independ ...

Incremental bias in Finapres estimation of baseline blood pressure levels over time.

Journal Article Hypertension · April 1997 Finapres finger blood pressure monitoring appears to provide a reliable alternative to intra-arterial blood pressure measurement under many circumstances. However, few studies have focused on the limitations of Finapres assessment. In a previous pilot inve ... Full text Link to item Cite

Cardiac vagal control and dynamic responses to psychological stress among patients with coronary artery disease.

Journal Article Am J Cardiol · December 15, 1996 Two groups of patients with coronary artery disease who differed in level of cardiac vagal control were compared in their cardiovascular responses to psychological stress. Patients with lower vagal control manifested increased reactions in diastolic blood ... Full text Link to item Cite

Noninvasive assessment of baroreflex control in borderline hypertension. Comparison with the phenylephrine method.

Journal Article Hypertension · August 1996 In this study, we examined the sensitivity of two recently developed noninvasive baroreflex measurement techniques to assess baroreflex control in hypertension. We assessed baroreflex sensitivity noninvasively from covariations of systolic pressure and RR ... Full text Link to item Cite

The effect of hypoxia on baroreflexes and pressor sensitivity in sleep apnea and hypertension.

Journal Article Sleep · December 1995 Many persons with sleep apnea are hypertensive. Forty-two subjects of similar age and weight were divided into four groups of hypertensives and normotensives with and without sleep apnea. All subjects had heart rate, blood pressure (BP), baroreflex sensiti ... Link to item Cite

Assessment of baroreflex control from beat-to-beat blood pressure and heart rate changes: a validation study.

Journal Article Psychophysiology · July 1995 In this study, we tested the validity of a new method designed to estimate baroreflex control of heart rate from spontaneous changes in systolic pressure and pulse interval. This method was compared with a conventional method of assessing baroreflex contro ... Full text Link to item Cite

Reduced beta 2-receptor mediated vasodilation in African Americans.

Journal Article Life Sci · 1995 It is well recognized that African Americans have a higher prevalence of cardiovascular disease than White Americans although the underlying mechanisms are not entirely understood. This study was perfumed to evaluate racial differences in the chronotropic ... Full text Link to item Cite

A technique for improved blood sampling during sleep studies.

Journal Article Psychophysiology · November 1994 Research protocols often require that blood samples be drawn during sleep. This study compares the efficacy of obtaining nocturnal blood samples using a standard heparinized intravenous setup versus the same intravenous setup used in conjunction with a sma ...

Mechanisms underlying cardiovascular defense reaction evoked by dorsal periaqueductal gray stimulation.

Journal Article Am J Physiol · November 1993 Hemodynamic and autonomic mechanisms underlying the cardiovascular defense reaction elicited by electrical stimulation of the dorsolateral periaqueductal gray region were evaluated in pentobarbital sodium-anesthetized Sprague-Dawley rats. Stimulation of th ... Full text Link to item Cite

Hypotensive effect of clonidine is not mediated by enhanced baroreflex gain in rats.

Journal Article J Cardiovasc Pharmacol · February 1993 We wished to examine whether enhanced depressor baroreflexes contribute to the hypotensive effect of clonidine in rats. Clonidine's hypotensive effect and clonidine's effect on baroreflex gain mean heart rate/mean blood pressure, (delta HR/delta BP) were c ... Full text Link to item Cite

Mechanisms underlying cardiovascular defense reaction evoked by dorsal periaqueductal gray stimulation

Journal Article American Journal of Physiology - Regulatory Integrative and Comparative Physiology · January 1, 1993 Hemodynamic and autonomic mechanisms underlying the cardiovascular defense reaction elicited by electrical stimulation of the dorsolateral periaqueductal gray region were evaluated in pentobarbital sodium- anesthetized Sprague-Dawley rats.

The effect of pentobarbital anesthesia on the autonomic nervous system control of heart rate during baroreceptor activation.

Journal Article J Auton Nerv Syst · November 1991 This study determined the influence of pentobarbital anesthesia on the autonomic nervous system control of baroreceptor mediated reflex bradycardia in the rat. Reflex bradycardia was elicited by phenylephrine-induced hypertension in conscious and pentobarb ... Full text Link to item Cite

Alpha 1-adrenergic receptor-mediated downregulation of angiotensin II receptors in neuronal cultures.

Journal Article J Neurochem · October 1986 Previous evidence has suggested that brain catecholamine levels are important in the regulation of central angiotensin II receptors.
