This research study is being done to determine levels of proteins that are normally present in the blood and urine of healthy individuals so as to compare to those levels in patients with heart disease.
Normal blood and urine will be analyzed for levels of proteins and cardiac peptides which are affected by heart disease in the elderly. We are trying to determine if there are normal age-related changes when heart disease is not involved.
