Regular high-intensity exercise linked with atrial fibrillation
In the second study, conducted by researchers in Sweden, more than 44,000 men between the ages of 45 and 79 were asked about their physical activity tendencies during the ages of 15, 30, 50 and during the past year of their life.
For an average of 12 years, the researchers tracked the participants' heart health to determine how many developed an irregular heart rhythm, also known as atrial fibrillation, which is a known stroke risk factor.
Results showed that men who exercised intensely for more than 5 hours a week were 19% more likely to develop an irregular heartbeat by 60 years of age, compared with those who exercised less than 1 hour a week.
However, those who did slightly less-intense exercises - such as cycling or briskly walking - for an hour a day or more at the age of 60 were 13% less likely to develop an irregular heartbeat than those who did not exercise at all.
but you know, talk to your local bro, it's more likely than not that he dabbles in cardiology
Can you link the full study?
It honestly reads like they asked 44,000 guys what they did for exercise and linked that to previous medical history and current health issues. If thats the case there are so many other variables here that can lead to health and/or heart problems.

rofl, all these mad kids....
Dr. David Ancona, a cardiologist with Memorial West in Pembroke Pines, Florida, says that it is very essential for people who lift weights to get a regular heart screening done. The reason is that lifting weights has a direct impact on the aorta, which is the heart's main artery. He says that lifting more than half your body weight will put an immense strain on your aorta, causing it to tear in some places.
Dr. John Elefteriades, chief of cardiothoracic surgery at Yale-New Haven Hospital, says that a rise in blood pressure from lifting heavier weights than half your body weight, can result in a torn aorta. The symptoms of a torn aorta are very similar to having a stroke. The pain is sharp and stabbing and it leads to the feeling of nausea, causing you to feel very light headed.
A study by cardiothoracic surgeons at Yale-New Haven Hospital in December of 2003 proved that there is a strong link between heart problems and weight lifting, and strength training as a whole. Dr. Elefteriades, who led the study, says that the study was conducted on five healthy individuals who suffered a condition called aortic dissection during weight lifting. The study showed that heavy weight lifting can lead to a rise in blood pressure to almost 300.
So Aortic Tears = irregular heart beats at 50+? None of these really prove your previous statement, two of them have absolutely no facts or study group and the 3rd has a participation group of 5 people, possibly already experiencing heart conditions hence why they were seeing a cardio thoracic surgeon...
