1 "Effects of Beta-Blockade on Cardiovascular Morbidity and Mortality in Elderly Trauma Patients: A Prospective Randomized Clinical Trial"

Advances in medical care have increased the proportion of elderly Americans and enabled them to remain more physically active. This has resulted in an unprecedented increase in the number of geriatric patients admitted to trauma centers. The elderly constitute 23% of trauma center admissions, but 36% of all trauma deaths. This disproportionately high mortality is attributable to a higher prevalence of pre-existing conditions, particularly, cardiac disease. Multi-system injuries result in critical cardiac stress. Although beta-blockade has been shown to decrease morbidity and mortality in patients at risk for myocardial infarction after elective surgery, their use in trauma patients with potential underlying cardiac disease has not been previously studied. We hypothesize that routine administration of beta-blockers after resuscitation will reduce morbidity and mortality in elderly trauma patients with, or at risk for, underlying cardiac disease. This study is a randomized, prospective clinical trial. One cohort will receive routine trauma intensive care, and the other, the same care plus beta-blockade after completion of resuscitation. The primary outcome will be mortality. Secondary outcomes include MI, length of stay, organ dysfunction, cardiac, and other complications. Changes in outcome may not be due to reduction in myocardial oxygen demand and heart rate. Laboratory studies demonstrate that circulating inflammatory cytokines contribute to cardiac risk in trauma patients, and their production is influenced by adrenergic stimulation. We will measure circulating IL-6, TNF alpha, IL-1beta, and measure NF-kB and p38 MAP kinase activation in peripheral blood leukocytes, and determine the effect of beta-blockade on the production of these inflammatory markers. Finally, the wide variation in patient response to beta-blockers is attributed to genetic variability in the adrenergic receptor. Therefore, we will identify single nucleotide polymorphisms (SNPS) within the beta-adrenergic receptor, and determine their effects on mortality and response to beta-blockade. This study will provide the first randomized, prospective trial designed to reduce morbidity and mortality in elderly trauma patients at risk for cardiac disease. The laboratory and genetic component will provide additional insights that may explain treatment effects, lead to new therapeutic strategies, and have the potential to lead to additional areas of investigation.

2 An Open Label, Pharmacogenetic Study of Bisoprolol Treatment in Patients With Uncontrolled Essential Hypertension (BRAVE)

This is an open-label, placebo run-in study to investigate the genetic and biomedical predictors of blood pressure response to bisoprolol. After informed consent is obtained, subjects will be withdrawn from previous antihypertensive therapy and given placebo for at least 2 weeks. Compliance will be assessed using pill counting, and any subject will a compliance less than 80% during the placebo run-in period will be excluded from the study. Bisoprolol 2.5 mg will be given once daily for 6 weeks. At baseline and after 6 weeks on bisoprolol 2.5 mg the clinic sitting blood pressure, 24-hour ambulatory blood pressure (if the patient is willing to do this), clinical characteristics and biochemical profile will be measured. Central aortic blood pressure will be measured with the A-PULSE device at baseline and after 6 weeks treatment. After completing 6 weeks treatment with bisoprolol 2.5 mg daily, the patient will continue treatment with bisoprolol for a total of 24 weeks unless there is any adverse event that requires discontinuation of bisoprolol.
