Electrocardiographic responses to deer hunting activities in men with and without coronary artery disease.

To evaluate the cardiac demands of hunting deer, continuous ambulatory electrocardiograms were obtained in men with and without coronary artery disease (CAD) and compared with their responses to maximal treadmill testing. A volunteer sample of 25 middle-aged men (mean +/- SD 55 +/- 7 years of age), 17 of whom had known CAD, completed the study. Peak heart rate (HR) during 7 different deer hunting activities was expressed as the mean percentage of the maximal HR (HRmax) attained during treadmill testing.

Optimal glycemic control is associated with a lower rate of target vessel revascularization in treated type II diabetic patients undergoing elective percutaneous coronary intervention.

Objectives: We examined the association between glycemic control determined by preprocedural hemoglobin A1c (A1c) and the incidence of target vessel revascularization (TVR) in diabetic patients undergoing elective percutaneous coronary intervention (PCI).

Background: Patients with diabetes mellitus (DM) have increased rates of restenosis and a worse clinical outcome after PCI than patients without DM.

Methods: A total of 239 patients (60 without DM and 179 with DM) were enrolled in this study.

Relation of hemoglobin A1c to rate of major adverse cardiac events in nondiabetic patients undergoing percutaneous coronary revascularization.

Abnormalities in plasma glucose below the "diabetic range" of glycemia are associated with increased cardiovascular morbidity and mortality in patients without diabetes mellitus. The purpose of this study was to investigate the relation between ambient glycemic levels as measured by hemoglobin A1c and outcome after elective percutaneous coronary intervention (PCI). Baseline laboratory studies, including hemoglobin A1c, were drawn in 500 consecutive patients before elective PCI.

Determinants of serum creatinine trajectory in acute contrast nephropathy.

The aim of this study was to describe the trajectory of creatinine (Cr) rise and its determinants after exposure to radiocontrast media. Included were 98 subjects who underwent cardiac catheterization and were randomized to forced diuresis with i.v.
