  • Current indication of untreated cardiovascular disease, e.g. planned work-up for ischemia.
  • History of myocardial infarction, apart from non-STEMI more than 1 year prior to the study, if the subject is currently revascularized and relevantly medicated.
  • Organic nitrate treatment Diagnosed secondary hypertension other than renal parenchymal hypertension (i.e. renal artery stenosis, primary hyperaldosteronism, low renin hypertension etc.)

Patients, who previously met the criteria for CKD I within the last 5 years, but no longer has proteinuria after relevant treatment, can also be included.
