Perceived physician financial conflicts of interest of can affect patient trust. Payment to physicians for industry sponsored clinical trials in multiple sclerosis is a relatively new potential source of physician conflict of interest. There is limited available data on how physician payment for trial involvement in multiple sclerosis clinical trials may influence patient trust.To understand how patient...
Generalized multilevel constructions for binary Reed-Muller R(r,m) codes using projections onto GF(2q) are presented. These constructions exploit component codes over GF(2),GF(4),...,GF(2q ) that are based on shorter Reed-Muller codes, and set partitioning using partition chains of length-2l codes. This is then used for deriving multilevel constructions for the Barnes-Wall A(r, m) family of lattices...
The early and late mortality in elderly patients (pts) who present with acute myocardial infarction (AMI) complicated by cardiac arrest (CA) is not established. We sought to identify baseline predictors of one-year mortality in this population who survived through discharge. We evaluated 163,223 patients 65 years of age or older with AMI in the Cooperative Cardiovascular Project database. Of these,...
Background: The incidence of dual AV node physiology (DNP) and AV node conduction properties in geriatric patients has not been defined.Methods: Applying conventional criteria, (abrupt change =<50 msec in AH and/or VA intervals with a ten msec decrement in atrial or ventricular extrastimuli), we compared the incidence of DNP in patients (pt) =<65 to those <65. Sixty-nine pts with AVNRT referred...
Background: Patients with renal insufficiency are at increased risk for acute myocardial infarction (AMI). However, its short and long term effect upon prognosis are not well understood. We sought to determine whether the admission serum creatinine (Cr) is an independent predictor of mortality in elderly patients with AMI.Methods: We evaluated Medicare beneficiaries age 65 years or older with a...
Despite advancement in the management of acute myocardial infarction (AMI), early and late mortality in elderly patients remains high. The occurrence of a cardiac arrest with AMI contributes substantially to the high early mortality. We sought to identify baseline characteristics of elderly patients presenting with AMI at risk for an early CA. Utilizing the Cooperative Cardiovascular Project (CCP)...
Beta blockers have been shown to decrease the incidence of atrial fibrillation (AF) following cardiac surgery. However, the use of magnesium is more controversial. It was our hypothesis that adjunctive magnesium sulfate (M) would improve the efficacy of beta blockers in the prevention of postoperative AF.Methods: We prospectively randomized 150 coronary artery bypass patients (mean age 61 +/- 10...
