Key result
Diminished renal function drives worse outcomes across heart failure, MI, and cardiac surgery.
Why the study?
Epidemiological evidence indicates that even mild renal function deterioration is an important risk factor for poor outcomes in patients with congestive heart failure, myocardial infarction, and cardiovascular surgery, prompting an examination of the kidney as both a marker and a pathogenic factor in cardiorenal syndromes.
This review analyzes the role of diminished renal function as both a risk marker and a pathogenic factor in cardiorenal syndromes and cardiovascular mortality.

Renal decline signals higher risk in HF and MI; leaves open causal mechanisms and targeted interventions.
The interactions between the heart and the kidney recently have been the focus of intense interest because of epidemiological evidence indicating that even mild deterioration of renal function is an important risk factor for poor outcome in patients with congestive heart failure, myocardial infarction, and cardiovascular surgery. Kidney function deterioration may be a consequence of cardiac and baroreceptor dysfunction or may be primarily caused by intrinsic kidney disease. This review provides a comprehensive analysis of the role of the kidney not only as a marker but also as a pathogenic factor in cardiorenal syndromes, whether primary heart or primary kidney disease or both are the initiators of the subsequent pathophysiological events.

Robert W. Schrier (2005) conducted a review in Cardiorenal syndromes (congestive heart failure, myocardial infarction, cardiovascular surgery, and diminished renal function). Diminished renal function was evaluated on Cardiovascular mortality and poor clinical outcomes. Diminished renal function acts as both a marker and a pathogenic factor for poor outcomes in cardiorenal syndromes across heart failure, MI, and cardiac surgery (review; no quantitative data stated).
