BACKGROUND It has not been clearly established whether percutaneous coronary intervention (PCI) can provide an incremental benefit in quality of life over that provided by optimal medical therapy among patients with chronic coronary artery disease. METHODS We randomly assigned 2287 patients with stable coronary disease to PCI plus optimal medical therapy(More)
Plasma selenium (Se), zinc (Zn) and copper (Cu) levels and antioxidant metalloenzymes, glutathione peroxidase (GPX) and superoxide dismutase (SOD), were studied in 17 patients on maintenance hemodialysis (HD) (group I), 14 uremic patients (group II) and 14 healthy subjects (group III). Plasma Se levels and erythrocyte GPX were significantly lower in the HD(More)
BACKGROUND Chronic kidney disease (CKD) is recognized as an independent cardiovascular disease risk state. The relationship between CKD and cardiovascular disease in volunteer and general populations has not been explored. METHODS The National Kidney Foundation Kidney Early Evaluation Program (KEEP) is a community-based health-screening program to raise(More)
The purpose of this retrospective cohort study was to examine the associations among chronic kidney disease, anemia, and risk of death among patients with heart failure. Retrospective cohort study. Patients with a principal diagnosis of heart failure (ICD9 codes 402.01, 402.11, 402.91, 404.01, 404.11, 404.91, and 428.xx) were included. Chronic kidney(More)
In normal subjects and diabetic patients, insulin suppresses whole body proteolysis suggesting that the loss of lean body mass and muscle wasting in insulinopenia is related to increased muscle protein degradation. To document how insulinopenia affects organ weights and to identify the pathway for accelerated proteolysis in muscle, streptozotocin-treated(More)
BACKGROUND Restenosis after implantation of coronary artery stents remains a significant clinical problem. We undertook a randomized, double-blind, placebo-controlled trial to determine whether cilostazol, a drug that suppresses intimal proliferation, would reduce renarrowing in patients after stent implantation in native coronary arteries. METHODS AND(More)
The ubiquitin-proteasome proteolytic system is stimulated in conditions causing muscle atrophy. Signals initiating this response in these conditions are unknown, although glucocorticoids are required but insufficient to stimulate muscle proteolysis in starvation, acidosis, and sepsis. To identify signals that activate this system, we studied acutely(More)
BACKGROUND The relationships of anemia, microalbuminuria, and estimated glomerular filtration rate (eGFR) with cardiovascular disease (CVD) and subsequent death are not fully understood. We hypothesized that each of these chronic kidney disease-related measures would have an independent relationship with CVD. METHODS A cohort of 37 153 persons screened in(More)
Coronary heart disease (CHD) is a major cause of morbidity and mortality in patients with chronic kidney disease or anemia. The purpose of this study was to examine whether the association between renal function and risk of CHD is modified by hemoglobin (Hgb) status. Analyses were based on data from the Atherosclerosis Risk in Communities study, a(More)
BACKGROUND Chronic kidney disease (CKD) has been linked to higher stroke risk. Anemia is a common consequence of CKD, and recent evidence suggests anemia may increase risk of cardiovascular events. The combined effect of CKD and anemia on stroke risk, however, has not been investigated thoroughly. We analyzed data from a middle-aged, community-based cohort(More)
