Heart failure marker

A method of treating or preventing heart failure in a subject identified as having an increased urinary angiotensinogen amount value, the method comprising:

• administering a heart failure drug to the subject identified as having an increased urinary angiotensinogen amount value for treating or preventing heart failure,
• wherein the urinary angiotensinogen amount value is a value obtained by measuring an angiotensinogen amount and a creatinine amount in a urine sample collected from the subject at a defined time and dividing urinary angiotensinogen mass by urinary creatinine mass, and the value is converted into “urinary angiotensinogen mass (μg)/urinary creatinine mass (g)”, and
• wherein the subject is identified as having an increased urinary angiotensinogen amount value when the measured urinary angiotensinogen amount value is 1.2 times or more than the value measured in a urine sample collected from the subject prior to the defined time.
