The Barostim Neo System is a device used to improve ejection fraction in certain heart failure patients.
Understanding Ejection Fraction and Heart Failure
Ejection fraction (EF) measures how well your heart pumps blood with each beat. A normal EF is generally between 55% and 70%. A lower EF, especially one at or below 35%, often indicates heart failure. Heart failure occurs when the heart can't pump enough blood to meet the body's needs.
The Barostim Neo System
The Barostim Neo System works by stimulating baroreceptors in the carotid artery. Baroreceptors are specialized nerve endings that sense changes in blood pressure and signal the brain to adjust heart function. By stimulating these baroreceptors, the Barostim Neo System can:
- Reduce sympathetic nervous system activity (the "fight or flight" response), which is often elevated in heart failure.
- Increase parasympathetic nervous system activity (the "rest and digest" response), which can help slow heart rate and improve heart function.
- Ultimately, improve the heart's ability to pump blood, leading to an improved ejection fraction.
Important Considerations
It's important to note that the Barostim Neo System is not for everyone with heart failure. It is specifically indicated for patients who:
- Have a regular heart rhythm.
- Are not candidates for cardiac resynchronization therapy (CRT).
- Have a left ventricular ejection fraction of ≤ 35%.
Other Devices and Treatments for Low Ejection Fraction
While the Barostim Neo System is a specific device aimed at improving ejection fraction, other treatments and devices are also commonly used in managing heart failure and improving EF:
- Medications: ACE inhibitors, ARBs, beta-blockers, diuretics, and other medications are often prescribed to manage heart failure symptoms and improve heart function.
- Cardiac Resynchronization Therapy (CRT): This involves implanting a special pacemaker that helps coordinate the contractions of the heart's ventricles.
- Implantable Cardioverter-Defibrillator (ICD): This device monitors heart rhythm and can deliver an electrical shock to correct life-threatening arrhythmias.
- Left Ventricular Assist Device (LVAD): This mechanical pump helps the heart circulate blood. It is typically used in patients with advanced heart failure.
- Heart Transplant: This is considered in severe cases of heart failure when other treatments have failed.
In conclusion, the Barostim Neo System is a device specifically designed to improve ejection fraction by stimulating baroreceptors, but it's only one of several treatment options available for managing heart failure and low ejection fraction.
