Have your heart failure monitored from the comfort of your home for improved quality of life

If you have heart failure, changes in the pressure of blood through your pulmonary artery (PA) can indicate worsening heart failure—even before you notice symptoms such as shortness of breath or weight gain. The CardioMEMS™ HF System features a small pressure-sensing device that is implanted directly into your pulmonary artery. Without needing to visit the clinic or hospital, it regularly sends information wirelessly to your care team. Your doctor can use the information to adjust your medications and treatment plan, if needed.

The CardioMEMS HF System is the first and only clinically proven heart failure monitor proven to significantly reduce heart failure hospital admissions and improve quality of life1; it has been clinically proven to reduce hospital admissions by 58% over an average of 12 months.2

Did you know?

  • Each time you are hospitalized for heart failure, your heart is damaged, which may contribute to your heart failure getting worse.1
  • Repeat hospitalizations for heart failure remain a strong predictor of illness and death for heart failure patients.2

Benefits of the CardioMEMS HF System include:

  • Your doctor can use the sensor information without needing to visit the clinic or hospital, it regularly sends information wirelessly to your care team.
  • It is simple and easy to use, with a home electronics unit that wirelessly sends data to your doctor.
  • The sensor does not need a battery or replaceable parts.

The CardioMEMS™ HF system measures your pulmonary artery pressure and heart rate through a sensor that is implanted in your pulmonary artery (the blood vessel that moves blood from your heart to your lungs). Once the device is implanted, you take daily pressure readings from the comfort of your home and wirelessly transmit the data to your doctor for continuous monitoring.

The sensor is small and does not require any batteries or wires. You will not feel it, and it will not interfere with your daily activities or other implanted devices such as a pacemaker or defibrillator.

The system includes an at-home electronics unit that you use to take the daily measurements. This is a simple and painless process that takes under a minute each day.

Watch this video to learn about how the CardioMEMS HF System works.

Staying Connected with the MyCardioMEMS App

Stay engaged in your care by using the myCardioMEMS™ app. The app allows you to see what days you uploaded readings and you can get reminders to take your heart failure medication. Your care team can also send you messages directly through the app about your readings and if you need to adjust your care plan. All of this can be done from the comfort of your home and without needing to go into the clinic.

Setting Up and Using Your CardioMEMS HF System for Monitoring from Home

If you have a pulmonary artery (PA) pressure monitoring sensor, taking PA pressure readings will now be part of your daily routine. Your CardioMEMS™ HF System comes with the equipment you need, including a quick-start guide that will lead you through the setup process. Be sure to follow any instructions your doctor gives you.

Instructions for using your CardioMEMS HF System


The system is portable, but most patients set it up in their bedroom for maximum efficiency. Electric blankets and waterbeds can cause interference with the system. If you have either an electric blanket or a waterbed, you may want to take your reading in another room.

The system includes:

  • Antenna: A paddle-shaped antenna inside your pillow, to make it easier and more comfortable for you to take readings.
  • Patient Electronics System: Reads the pressure measurement from your sensor wirelessly. For instructions on setting up the system, refer to the CardioMEMS Patient Electronics System guide that was included with the system.

If you are having trouble getting a signal or it is taking longer than usual to set up your CardioMEMS HF System, please contact Technical Support at +1-844-MYCMEMS or 1-844-692-6367.

Why Would I Use A Pulmonary Artery (PA) Pressure Monitoring System?

From your home unit, your sensor information is sent wirelessly to your doctor so they can proactively assess your condition and reduce your chances of developing new symptoms or going to the hospital.

How will the CardioMEMS HF System help change my life?

The CardioMEMS™ HF System gives your heart failure care team the information they need to manage your care from home thereby reducing your need for clinic visits and reducing your chances of a heart failure hospitalization.

Is The CardioMEMS HF System Complicated To Use?

The system is easy to use, and patients will be trained to use the system before they are released from the hospital. The system also comes with startup instructions and a user’s guide.

Can I Talk To A Patient Who Has The CardioMEMS HF System To Hear About Their Experience?

Yes, speak with a heart failure patient about their experience with the CardioMEMS HF system by calling 1-855-4-CMEMSHF (1-855-426-3674) to get connected.

How Often Do I Need To Use The CardioMEMS HF System?

You will use the system every day to send PA pressure readings to your doctor. It only takes a few minutes.

Can I Have A Magnetic Resonance Imaging (MRI) Scan With My PA Sensor?

You can have an MRI scan under certain conditions. Talk with the doctor ordering your MRI scan to ensure that he or she knows that you have a CardioMEMS PA sensor.

Learn more about electromagnetic interference (EMI) and MRI testing.

Can I Pass Through Airport Security Or Anti-Theft Systems With My PA Sensor?

Yes; your sensor will not alert or be affected by airport security or anti-theft systems that require you to pass through a metal detector or scanning machine.

We provide an ID card and a letter that contain relevant information related to your device, which you can show to security and airline personnel when traveling. Download the letter and visit the patient ID card page for more information.
