NCT00123604 ↗	Vascular Effects of Carvedilol Versus Metoprolol in Hypertensive Patients With Type 2 Diabetes	Completed	St. Paul Heart Clinic	Phase 4	2004-06-01	The purpose of this study is to compare the vascular effects of two commonly used blood pressure medications, carvedilol and metoprolol in hypertensive patients with type 2 diabetes.
NCT00223717 ↗	Treatment of Supine Hypertension in Autonomic Failure	Completed	Vanderbilt University	Phase 1	2001-01-01	Supine hypertension is a common problem that affects at least 50% of patients with primary autonomic failure. Supine hypertension can be severe, and complicates the treatment of orthostatic hypotension. Drugs used for the treatment of orthostatic hypotension (eg, fludrocortisone and pressor agents), worsen supine hypertension. High blood pressure may also cause target organ damage in this group of patients. The pathophysiologic mechanisms causing supine hypertension in patients with autonomic failure have not been defined. In a study, we, the investigators at Vanderbilt University, examined 64 patients with AF, 29 with pure autonomic failure (PAF) and 35 with multiple system atrophy (MSA). 66% of patients had supine systolic (systolic blood pressure [SBP] > 150 mmHg) or diastolic (diastolic blood pressure [DBP] > 90 mmHg) hypertension (average blood pressure [BP]: 179 ± 5/89 ± 3 mmHg in 21 PAF and 175 ± 5/92 ± 3 mmHg in 21 MSA patients). Plasma norepinephrine (92 ± 15 pg/mL) and plasma renin activity (0.3 ± 0.05 ng/mL per hour) were very low in a subset of patients with AF and supine hypertension. (Shannon et al., 1997). Our group has showed that a residual sympathetic function contributes to supine hypertension in patients with severe autonomic failure and that this effect is more prominent in patients with MSA than in those with PAF (Shannon et al., 2000). MSA patients had a marked depressor response to low infusion rates of trimethaphan, a ganglionic blocker; the response in PAF patients was more variable. At 1 mg/min, trimethaphan decreased supine SBP by 67 +/- 8 and 12 +/- 6 mmHg in MSA and PAF patients, respectively (P < 0.0001). MSA patients with supine hypertension also had greater SBP response to oral yohimbine, a central alpha2 receptor blocker, than PAF patients. Plasma norepinephrine decreased in both groups, but heart rate did not change in either group. This result suggests that residual sympathetic activity drives supine hypertension in MSA; in contrast, supine hypertension in PAF. It is hoped that from this study will emerge a complete picture of the supine hypertension of autonomic failure. Understanding the mechanism of this paradoxical hypertension in the setting of profound loss of sympathetic function will improve our approach to the treatment of hypertension in autonomic failure, and it could also contribute to our understanding of hypertension in general.

NCT00246519 ↗	Pharmacogenomic Evaluation of Antihypertensive Responses	Completed	University of Florida	Phase 4	2005-10-01	There are many medications available for the treatment of high blood pressure (hypertension), but finding the right one for a specific patient can be challenging. In fact, it is estimated that only 34% of people with hypertension have their blood pressure under control. The hypothesis is that genetic differences between individuals influence their response to antihypertensive medications. This study is aimed at determining the genetic factors that may influence a person's response to either a beta-blocker or a thiazide diuretic. The hope is that through this research, we may someday be able to use an individual's genetic information to guide the selection of their blood pressure medicine, leading to better control of blood pressure, and less need for the current trial and error process.
NCT00401882 ↗	Treatment of Ventricular Tachyarrhythmias Refractory To Shock With Beta Blockers: The SHOCK and BLOCK Trial	Terminated	Medtronic BRC	Phase 2	2007-01-01	The purpose of this research study is to evaluate the effectiveness of metoprolol, a "beta blocker," in treating patients in the hospital with a cardiac arrest. It will be given intravenously (given into a vein). The subjects who will take part in this study are 18 years of age or older, are experiencing a cardiac arrest in the hospital, and are in a life threatening situation. Patients who develop a cardiac arrest require prompt electrical defibrillation (electrical shocks) to restore the normal beating rhythm of the heart. In patients who do not respond to electrical defibrillation, current standard of care recommends the use of medications which have been shown to be of unknown benefit. Some people recover from a cardiac arrest, but many people do not. We want to learn whether giving metoprolol will improve survival of patients with a cardiac arrest. A total of 100 patients will be enrolled in the study. Patients will receive either the standard of care with the drug epinephrine or the standard of care plus metoprolol.
