Cardiovascular diseases are among the world’s leading causes of death. Therefore, itis important to define advanced heart failure using signs and symptoms, hemodynamics,
exercise testing, biomarkers, and risk prediction models. However, most medical and
device therapies fail to define stage-D heart failure. Therefore, there is a need to develop a
method to synchronize Cardiac Compression Devices with the heart of those patients who
suffer from Stage‐D heart failure. Previous cardiac compression devices do not synchronize
with cardiac contraction mechanics and their natural direction, and some cannot help with
the diastolic phase of the cardiac cycle. Therefore, the devices were not synchronized with
a pacemaker to compress the heart when the heart paces irregularly and slowly. The
method discussed in this paper uses a synchronized rotation mechanism of a servo motor
via a pacemaker to compress the heart. The servo motor is synchronized with the
pacemaker to help with this process and follows the heart’s movement. For the purpose of
this project, the servo motor was used to rotate clockwise and counter-clockwise at a set
angle continuously to help compress the heart. A potentiometer was used to set the Pulse
Width Modulation (PWM) to control the angular speed of the motor; in this case, the motor
has the ability to rotate at different angular speeds to help compress the heart as needed
based on the patient’s heart conditions. This method aims to improve the quality of life and
extend the life expectancy of patients with Stage‐D heart failure since they do not currently
have any other options than palliative care to alleviate their congestive heart failure
symptoms. To improve the system in the future, the system should be built with higher
quality motors, reducing the possibility of collecting noise. All systems including the
required sensing of pacemaker and motor wiring should be checked for loose connections
as any human error could cause a shift in the results. This biological system will have to
undergo in vivo and vitro testing prior to clinical trials such as large animal testing such as
pigs, sheep, and dogs to provide with safety information and activity of cellular
products. For vitro testing, ideally, the hyperpolarization-activated cyclic nucleotide gene
family is suited to function as a pacemaker when overexpressed. Finally, the synchronized
system that compresses the heart can be used to help patients with stage-D heart failure by
improving their cardiac output with no need for donors and open-heart surgery which is
not safe due to their health conditions.
