Kidney function tests plus data on proteinuria give better estimate of mortality risk

Combining the results of kidney function tests and urine analysis may improve the accuracy of estimates of risk for all cause mortality in people with coronary disease. Tonelli and colleagues (p 1420) analysed data on proteinuria, kidney function, and all cause mortality of 4098 adults with previous myocardial infarction. Compared with participants without proteinuria or impaired kidney function, patients with both characteristics were at high risk (hazard ratio 2.39, 95% CI 1.72 to 3.30), and those with only one characteristic were at intermediate risk of dying from any cause.
