The CDC recommends 150 minutes of moderate-intensity exercise and two days of muscle strengthening each week, but what about those people who take their workouts to the next level – could that actually have a negative impact on their heart?

Dr. Oza says this new way of treating AFib patients is a breath of fresh air when other methods like ablations do not work on patients like Preis.

February is American Heart Month.

Scientists are using ex-vivo, or beating donated human hearts, to test a new way of pinpointing the source of AFib.

Atrial Fibrillation, or AFib, is an irregular heartbeat that can cause poor blood flow. Atrial Fibrillation, or AFib, is an irregular heartbeat that can cause poor blood flow. Patients received the standard medication, or a cryo balloon ablation. After a year, 75% of the patients who received an ablation were still free from AFib. AdIn comparison, only 45% of the patients who received medication were still AFib-free.

Copyright 2019 CNNAccording to new research, retired National Football League players have a higher risk for atrial fibrillation, or AFib, a type of irregular heartbeat that can lead to stroke. Researchers screened 460 former NFL players and compared them to 925 men of about the same age, who werent professional athletes. They also had a slightly increased risk of needing a pacemaker, a lower incidence of high blood pressure and better cholesterol control. He adds that retired NFL players and their loved ones need to make sure heart rhythm screening is part of an annual checkup. He said the research should not discourage anyone from mild to moderate exercise, because AFib risk actually decreases for the average person with exercise.

Atrial fibrillation, or AFib, is an irregular heartbeat that can lead to blood clots, stroke and heart failure. Dr. Rolf Bodmer, a professor at Sanford Burnham Prebys, and Dr. Karen Ocorr, an assistant professor at Sanford Burnham Prebys, are a husband and wife team working to mend broken hearts. They spend their days -- and sometimes their nights -- looking for the genetic mechanism that causes AFib. Ocorr believes theyll find a genetic network for atrial fibrillation. Theyre already getting AFib patient tissue samples from cardiologists around the world for further testing.
