Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Summary
Brief summary
This project is designed to assess myocardial ischemia in various populations of patients with renal disease. These cohorts of patients have significant cardiovascular morbidity and mortality. It is believed that apart from epicardial coronary disease, they also have microvascular or small vessel ischemia. Dialysis is thought to be a major contributor in acceleration of their cardiovascular disease, however even after renal transplantation, there cardiovascular morbidity and mortality does not mirror the general population. We are going to assess myocardial ischemia using cardiac MRI and blood oxygen level dependent imaging. This uses intrinsic contrast of deoxy-hemoglobin to assess ischemia. We are going to assess it in patients on dialysis regardless of their cardiovascular symptoms as this group of patients have significant disease despite lack of traditional cardiac symptoms. We are also going to look at patients being evaluated for renal transplant. In this population, we can directly compare this relatively new technique with traditional method of ischemia assessment. We believe this technique will provided added information to already existing imaging modalities as it looks at oxygenation of the myocardium, which precedes development of ischemia. Our third cohort, evaluates patients after their renal transplant, examining markers that may predict cardiovascular morbidity and mortality in this group. This trial is the end stage renal disease cohort and is linked to ACTRN12611000783921 and ACTRN12611000786998
