This show looks at the interesting connection between the health of your kidneys and your heart. Your kidneys may be an excellent predictor of heart and blood vessel disease, and this interview explores that link. In part one of this two part interview, Dr. Matthew Weir discusses blood filtering, urine production, causes of kidney disease, blood vessel damage in the kidneys, kidneys as predictors of heart attack and stroke, kidney function tests, creatinine, protein in urine, and screening for kidney filtering ability.
