Elasticity of a cardiovascular vessel of a patient is monitored to provide an indication of whether the patient's health is changing. In some aspects the elasticity of a cardiovascular vessel is determined irrespective of the current blood pressure level of the patient at the time the elasticity is determined. For example, vessel elasticity may be determined based on a defined set of data that maps vessel elasticity with reflectance times for different blood pressure levels. In some implementations, this set of data corresponds to a set of iso-pressure lines.
