MONDAY, Sept. 16, 2019 -- Debate over the benefits and drawbacks of daily low-dose aspirin has flared in recent years, with guidelines now generally urging against the regimen to prevent a first heart attack or stroke in healthy people.
But some people with good heart health still might benefit from taking daily low-dose aspirin, a new study from New Zealand argues.
THURSDAY, Aug. 8, 2019 (American Heart Association News) -- Low vitamin D levels do not lead to strokes but can result from them, according to the latest study that looks at the relationship between the two.
Vitamin D is mostly known for helping the body absorb calcium and contributing to bone health. But research in recent decades also has looked at whether vitamin D levels affect cardiovascular disease, although with inconsistent results.
MONDAY, Aug. 26, 2019 (American Heart Association News) -- Exercise is important for health and wellbeing. But past studies suggest high-intensity exercise may be a risk factor for an irregular heart rhythm called atrial fibrillation that sometimes leads to stroke. So, are athletes who develop A-Fib at higher risk for stroke?
Researchers in Sweden looked at men and women who completed one or more races in the 30- to 90-kilometer cross-country skiing event called Vasaloppet from 1989 through 2011, comparing them to a group of non-skiers. The investigators hypothesized high-intensity exercise would increase the risk of A-Fib, thus leading to more strokes in the ski group. But they discovered the opposite may be true.
THURSDAY, July 25, 2019 -- Despite improved air quality since the 1990s, pollution still causes lung disease, heart attacks and strokes that kill more than 30,000 Americans each year, a new study estimates.
Researchers looked at concentrations of fine pollution particles known as PM2.5 across the country from 1999 to 2015. These tiny particles -- 30 times smaller than the width of a human hair -- come from the combustion of cars, coal-fired power plants and other industrial sources.
