CONTEXT Patients who have atrial fibrillation (AF) have an increased risk of stroke, but their absolute rate of stroke depends on age and comorbid conditions. OBJECTIVE To assess the predictive value of classification schemes that estimate stroke risk in patients with AF. DESIGN, SETTING, AND PATIENTS Two existing classification schemes were combined(More)
BACKGROUND Congestive heart failure is the most common indication for admission to the hospital among older adults. Behavioral factors, such as poor compliance with treatment, frequently contribute to exacerbations of heart failure, a fact suggesting that many admissions could be prevented. METHODS We conducted a prospective, randomized trial of the(More)
BACKGROUND Although warfarin and other anticoagulants can prevent ischemic events, they can cause hemorrhage. Quantifying the rate of hemorrhage is crucial for determining the risks and net benefits of prescribing antithrombotic therapy. Our objective was to find a bleeding classification scheme that could quantify the risk of hemorrhage in elderly patients(More)
The aim of this updated guideline is to provide comprehensive and timely evidence-based recommendations on the prevention of future stroke among survivors of ischemic stroke or transient ischemic attack. The guideline is addressed to all clinicians who manage secondary prevention for these patients. Evidence-based recommendations are provided for control of(More)
BACKGROUND Age is an important determinant of outcomes for patients with acute coronary syndromes (ACS); however, community practice reveals a disproportionately lower use of cardiovascular medications and invasive treatment even among elderly patients with ACS who would stand to benefit. Reasons include limited trial data to guide the care of older adults(More)
BACKGROUND Age is an important determinant of outcomes for patients with acute coronary syndromes. However, community practice reveals a disproportionately lower use of cardiovascular medications and invasive treatment even among elderly patients who would stand to benefit. Limited trial data are available to guide care of older adults, which results in(More)
Decreased heart rate (HR) variability is an independent risk factor for mortality in cardiac populations. Clinical depression has also been associated with adverse outcomes in patients with coronary artery disease (CAD). This study tests the hypothesis that depressed patients with CAD have decreased HR variability compared with nondepressed CAD patients.(More)
Little is known about the effects of depression on adherence to medical treatment regimens in older patients with chronic medical illnesses. Poor adherence may explain the increased risk of medical morbidity and mortality found in depressed medical patients. Ten of 55 patients over the age of 64 with coronary artery disease met the criteria for major(More)
BACKGROUND Worsening renal function in patients hospitalized for heart failure portends a poor prognosis. However, criteria used to define worsening renal function are arbitrary, and the implications of different definitions remain unclear. We therefore compared the prognostic importance of various definitions of worsening renal function in 1,002 patients(More)
OBJECTIVE To examine the fertility concerns and sexual behavior of adolescent girls with polycystic ovary syndrome (PCOS) as compared to healthy adolescent girls and the effect of these concerns on health-related quality of life. DESIGN AND SETTING A cross-sectional study of adolescent girls with PCOS (n = 97) and healthy comparisons (n = 186) was(More)
