In another recently published study, this one in the Journal of the American College of Cardiology: Heart Failure, investigators sought to see if there was a relationship between the urinary microalbumin creatinine ratio (UACR) and cardiac structure and/or function in patients with heart failure. They measured the UACR and did echocardiography studies on 144 subjects with heart failure who also had a preserved ejection fraction. A number of factors were evaluated including left ventricular mass, right ventricular (RV) systolic function and RV remodeling. They found that for each doubling of the UACR, there was a statistically significant increase in RV wall thickness of 0.9 mm. and RV systolic functioning was diminished with a 0.56% lower fractional area change. The authors concluded that the UACR functioned as a prognostic marker that was independently associated with worse outcomes in this patient population.
