Problems solved by technology

Conversely, mechanically unloading the LV at a flow rate slightly less than the fill rate increases the LV volume and MVO 2 , and thus make it difficult to reduce the infarct size of the LV
Therefore, manual control of the cardiac pump to optimally unload the LV is impractical, ineffective, and potentially life-threatening

Abstract

Various systems, devices, and methods are disclosed herein for healing acute myocardial infarction (AMI) patients using a heart, pump controlled in a maimer that maximizes mechanical unloading of the left ventricle in the presence of cardiovascular instability and minimizes myocardial oxygen consumption (MVO2) and consequentially infarct size to prevent the development of subsequent heart failure. In a closed feedback system, the system can include a sensor configured to generate an output used to measure or calculate a left ventricular systolic pressure (LSVP) within the left ventricle of a heart and a controller coupled to a heart, pump. The controller can be configured to measure or calculate the LVSP based on the output of the sensor and to control an operation of the heart pump to maximize mechanical unloading of the left ventricle based on the measured or calculated LVSP.

Description

[0001] Cross References to Related Applications [0002] This application claims a U.S. patent entitled "Systems and Methods for Controlling a Heart Pump to Minimize Myocardial Oxygen Consumption," filed July 31, 2018 Priority and benefit to application 16 / 050,542, the entire contents of which applications cited above are hereby incorporated by reference. technical field [0003] The present disclosure relates to systems for controlling a heart pump and related methods for treating patients with acute myocardial infarction (AMI), and in particular to controlling the operation of a heart pump to prime the left ventricle (LV) during treatment of AMI patients. Maximizing mechanical unloading and maximizing myocardial oxygen consumption (MVO 2 ) and thus a closed feedback control system that minimizes infarct size to prevent the development of long-term heart failure. Background technique [0004] AMI, commonly known as a heart attack, is a potentially life-threatening conditi...
