Substance in crude oil harms fish hearts, could affect humans as well.
Experiments provide direct evidence of how phenanthrene causes irregular heartbeat and weaker contractions of heart cells.Urban air pollution, laden with PAHs, has been implicated in cardiac distress. The current study points the finger at phenanthrene, which could enter the bloodstream through respiratory pathways such as breathing.The researchers also suggest that atmospheric phenanthrene deserves more attention for the possible impact it could have on the cardiovascular health of people. Better understanding of the connection between phenanthrene and human health could potentially lead to insights regarding which aspects of fossil-fuel bur

For healthier arteries, do as Amazon rainforest inhabitants do
The Tsimane living in the Amazon have the lowest reported levels of age-related hardening of the arteries in the world, say researchers who encourage Westerners to learn from these Bolivian rainforest inhabitants. Atherosclerosis was thought to be a natural part of aging. Even Egyptian mummies have shown signs of plaque buildup in the arteries. For the study in Friday's medical journal The Lancet, cardiologists focused their low-radiation CT scanners on the Tsimane, a forager-horticulturalist population that eats mainly wild, lean game, plantain, rice and maize, and fruits and nuts.

Lotus inspires stent designers
The self-cleaning abilities of a popular plant provides clues to cutting deaths linked to stent surgery. The number of cyborgs in our midst is growing rapidly. From heart to hip, many of us will end up with a medical implant at some time in our lives. In Australia, stent implants to unblock coronary arteries are one of the top five procedures in hospital emergency rooms, but once inserted into the body, the surface of implants can cause life-threatening blood clots or bacterial infections.

Go Ahead, Hackers. Break My Heart
MY LIFE DEPENDS on the functioning of a medical device: a pacemaker that generates each and every beat of my heart. I know how it feels to have my body controlled by a machine that is not working correctly, and this is why I encourage fellow security researchers to delve into these medical devices and find ways to make them more secure. Four years ago, I woke up lying on the floor, but I had no idea how I’d gotten there or for how long I’d been out.

Chocolate is not a super food
Listen: we all want to believe that we make good choices. It doesn't matter if I douse my lettuce in fatty salad dressing, it's still good for me. Yes, there is an awful lot of sugary granola in my yogurt but hey, it's Greek yogurt. And maybe I do eat a lot of chocolate, but so what? It's good for my heart!

Noisy cities disrupt heartbeat and could trigger disease, study suggests
The cacophony of noise town centres could trigger heart problems, a new study suggests, after scientists found that fluctuating sounds on busy high streets disturb normal cardiac rhythms. Researchers from Nottingham Trent University found that constant changes in noise – even at low levels – had an immediate and disruptive effect on the patterns of participants’ normal heart rates.

Popular class of drugs reverse potentially harmful genetic changes from heart disease
Beta blockers are commonly used world-wide to treat a variety of cardiovascular conditions, such as arrhythmias and heart failure. Scientists have known for decades that the medications work by slowing the heart rate and reducing the force of contraction - lessening the burden of work carried out by the heart. However, new research out of York University has now shown that these drugs also reverse a number of potentially detrimental genetic changes associated with heart disease.

Is the American Heart Association a terrorist organization?
The AHA receives very substantial donations from various pharmaceutical companies who also, conveniently, produce cholesterol lowering medications. Conagra, Quaker Oats, Monsanto and Campbell Soups are all listed among the AHA’s lifetime donors of $1,000,000.00 or more in the AHA’s 2012-2013 annual report.
