New index for assessing the chronotropic response in patients with end‐stage liver disease who are undergoing dobutamine stress echocardiography
Wojciech Rudzinski, Alfonso H. Waller, Amit Prasad, Sunita Sood, Christine Gerula, Arun Samanta, Baburao Koneru, Marc Klapholz – 5 December 2011 – The inability to achieve 85% of the maximum predicted heart rate (MPHR) on dobutamine stress echocardiography (DSE) is defined as chronotropic incompetence and is a predictor of major cardiac events after orthotopic liver transplantation (OLT). The majority of patients with end‐stage liver disease (ESLD) receive beta‐blockers for the prevention of variceal bleeding.
