Coronary artery bypass grafting and percutaneous coronary intervention in patients with end-stage renal disease.

Objectives: To determine the relative risks of long-term mortality between coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) among patients with end-stage renal disease (ESRD).

Methods: We identified 1015 patients with ESRD who underwent coronary revascularization between 1996 and 2008 within Kaiser Permanente Northern California. We obtained clinical variables from health plan databases, state death certificates and social security administration files.

Combined rest redistribution thallium-201 SPECT and low-dose dobutamine contractility assessment in a simple and practical new viability protocol.

Objective: Rest-redistribution (RR) thallium-201 (Tl-201) imaging is commonly used for myocardial viability evaluation. Contractile reserve (CR) assessment with low-dose dobutamine (LDD) is another method that highly predicts functional recovery following revascularization. In this study, we investigate the feasibility of a new protocol that provides combined Tl-201 uptake, resting and CR functional regional myocardial information in a single examination.
