Abstract: BACKGROUND AND OBJECTIVE Aortic pressure (Pa) is important for the diagnosis of cardiovascular disease. However, its direct measurement is invasive, not risk-free, and relatively costly. In this paper, a new simplified Kalman filter (SKF) algorithm… read more here.

Abstract: BACKGROUND Aortic reflected wave magnitude (RM) may not account for sex-specific differences in aortic pressure augmentation in Caucasians. However, aortic reflected waves are greater in groups of African descent than other ethnic groups. We determined… read more here.

DOI: 10.1097/01.hjh.0000523410.59496.44
Abstract: Objective: Augmentation index (AIx) reflects aortic pressure augmentation and is independently associated with cardiovascular risk in adults. It is determined by structural and functional cardiovascular properties and increases with aging. This study examined AIx in… read more here.

DOI: 10.1111/aor.14307
Abstract: Abstract Background Existing working heart models for ex vivo functional evaluation of donor hearts often use cardiac afterloads made up of discrete resistive and compliant elements. This approach limits the practicality of independently controlling systolic… read more here.
