The Challenges of Post-CABG and A-fib


The challenges of Post-CABG and A-Fib

According to the SEARCH-AF study, one in five people who undergo coronary artery bypass graft surgery (CABG) later developed atrial fibrillation or atrial flutter.

CABG is a procedure to treat coronary artery disease. The surgery consists of restoring normal blood flow and oxygen supply to an obstructed coronary artery. It's done by taking a healthy blood vessel from another part of the body, such as the chest, leg, or arm and attaching it to the aorta, the other is attached beyond the narrowing or blockage.

1 in 5 people who undergo CABG later develop Afib or flutter

The researchers emphasized that 30% to 50% may develop postoperative atrial fibrillation right after CABG. Still, if patients don't develop atrial fibrillation in the hospital after cardiac surgery, it doesn't mean they are not at risk to develop it later on.


Atrial fibrillation (AFib) is an irregular heartbeat (arrhythmia) that can lead to blood clots, stroke, heart failure, and other heart-related complications. At least 2.7 million Americans are living with AFib.

At the moment, clinical guidelines provide little direction on the optimal duration for monitoring patients after cardiac surgery to detect atrial fibrillation. If physicians could detect AFib in the early weeks after patients have been discharged, it would be easier to identify those who might benefit from oral anticoagulation to prevent strokes.


It's vital to treat patients right away when they have a high CHADS2 score (clinical predictor for strokes) and are found to have Afib post-operatively.

Atrial Fibrillation is estimated to affect up to 6.1 million people in the US and over 33 million worldwide. Detection can help prevent up to 80% of related strokes, decrease cardiac morbidity and mortality, and decrease post-procedure complications. Arrhythmias like AFib are best detected using an ECG, however, AFib may be intermittent and an ECG taken at the doctor's office may not detect any arrhythmia. Having a device like the Avidhrt Sense in the palm of your hand is key to monitoring and early detection.


At Avidhrt we strongly believe prevention and early detection of cardiovascular disease saves lives. The Avidhrt Sense is a mobile, clinical-quality electrocardiogram (ECG), pulse oximeter (SpO2), and infrared temperature sensor. With Avidhrt, you can monitor your heart anywhere, any time, and even share that data with your physician. If you feel any symptoms, call your doctor right away.
