Additional Study Information: Heart disease is the leading cause of complications among liver transplant recipients. We know that blood pressure is a heart disease risk factor, but it is unclear how blood pressure levels affect outcomes in liver transplant recipients. We are interested in how we can better measure blood pressure levels after liver transplantation. As a participant in the study, we will periodically ask you to measure your blood pressure at home, complete some questionnaires, and also provide research blood and urine specimens. Your participation in the study will last approximately 5 years.
