A study from UCSD scientists reports finding a reason why cardiovascular disease is the single biggest killer of men and women alike. It’s a mutation that occurred millions of years ago in our prehuman ancestors.The mutation blocked production of a cellular signaling molecule used by other animals, including ape cousins. Humanity’s vulnerability to heart disease appears to be linked both to the absence of this molecule in people and consumption of red meat, which contains it.Because this molecule is nonhuman, it causes an immune reaction that raises the risk of heart attacks, the authors state. Moreover, its absence alone may increase the risk compared to chimpanzees, humanity’s closest relative.The study was published Monday in the Proceedings of the National Academy of Sciences. It can be found online at http://j.mp/heartvarki. Heart disease is actually common in both humans and captive chimps, but the causes are different. Humans experience atherosclerosis, or … [Read more...] about Heart disease is the price of becoming human, UCSD study finds
Heart attack heart rate
Long gone are the days of having to measure your resting heart rate by placing two fingers against your neck and watching the clock. Now, it's as easy as firing up a smartphone app or saying, "Siri, what's my heart rate?" But interpreting the number you get back? That can be a bit more complicated.Read more: The best iPhone and Apple Watch health devices for checking blood pressure, heart rate and more What's a normal resting heart rate? Resting heart rate (RHR)—the number of times your heart beats per minute at rest—is a quick way to gauge how efficiently your heart is working. What's considered normal can vary widely from person to person, but in general, your RHR should fall between 60 and 100 beats per minute. If your RHR is consistently above 100 beats per minute (a condition known as tachycardia), you should consult a doctor, especially if you're experiencing other symptoms, such as chest tightness, fatigue or shortness of breath. "An … [Read more...] about What is considered a normal resting heart rate?
Acute coronary syndrome (ACS) — an umbrella term for situations where blood flow to the heart is suddenly obstructed — can lead to a heart attack if left untreated, and that’s obviously bad news. According to the Center for Disease Control and Prevention, over 610,000 people die of heart disease every year, which is the leading cause of death for both men and women in the U.S. Fortunately, scientists at IBM and pharmaceutical giant AstraZeneca are investigating a machine learning framework that can suss out early warning ASC warning signs. It’s described in a newly published paper (“Outcome-Driven Clustering of Acute Coronary Syndrome Patients using Multi-Task Neural Network with Attention“) on the preprint server Arxiv.org. The team sourced a dataset containing the age, gender, personal disease history, habits, laboratory test results, procedures, ACS type, and nearly 40 other characteristics of 26,986 adult hospitalized patients across 38 urban and … [Read more...] about AI predicts precursors to heart attacks

Why, the Patriots of course. They’re in another Super Bowl, and the patient is tensing for another heart-in-throat, down-to-the-wire ending.Despite what the rest of the nation may think — what with our regular appearances in the Super Bowl, the five rings, the dynasty and all — being a Patriots fan is hard on the body and mind (there is actual science on this). And not only that, but Pats fans have it harder than other fans of other NFL teams (there is no actual science on this).

A new report estimates that nearly half of all U.S. adults have some form of heart or blood vessel disease, a medical milestone that's mostly due to recent guidelines that expanded how many people have high blood pressure.The American Heart Association said Thursday that more than 121 million adults had cardiovascular disease in 2016. Taking out those with only high blood pressure leaves 24 million, or 9 percent of adults, who have other forms of disease such as heart failure or clogged arteries.Measuring the burden of diseases shows areas that need to improve, the heart association's chief science and medical officer, Dr. Mariell Jessup, said in a statement.RELATED: Are you having a heart attack? 7 PHOTOS Silent signs of a heart attack See Gallery Silent signs of a heart attack Fatigue Dr. Stacey E.
