Cardiac support refers to the use of medical devices or therapies to assist the functioning of the heart in patients with heart failure or other cardiac conditions. These devices can help to improve the pumping ability of the heart, regulate heart rhythm, or provide temporary support until a more permanent solution, such as a heart transplant, can be performed. Cardiac support devices include ventricular assist devices (VADs), pacemakers, defibrillators, and cardiac resynchronization therapy devices. Overall, cardiac support aims to improve the quality of life and long-term outcomes for individuals with heart problems.
