Common Food Nutrient Tied to Risky Blood Clotting

Posted 1 day 12 hours ago by Drugs.com

MONDAY, April 24, 2017 – A nutrient in meat and eggs may conspire with gut bacteria to make the blood more prone to clotting, a small study suggests. The nutrient is called choline. Researchers found that when they gave 18 healthy volunteers choline supplements, it boosted their production of a chemical called TMAO. That, in turn, increased their blood cells' tendency to clot. But the researchers also found that aspirin might reduce that risk. TMAO is short for trimethylamine N-oxide. It's produced when gut bacteria digest choline and certain other substances. Past studies have linked higher TMAO levels in the blood to heightened risks of blood clots, heart attack and stroke, said Dr. Stanley Hazen, the senior researcher on the new study. These findings, he said, give the first direct evidence that choline revs up TMAO production in the human gut, which then makes platelets (a type of ... Read more

Blood Pressure: Know Your Numbers

Posted 8 days ago by Drugs.com

TUESDAY, April 18, 2017 – Having high blood pressure makes you more likely to have heart disease or a stroke. But because high blood pressure doesn't usually cause warning symptoms, you could be at risk without even knowing it. That's why it's important to have your blood pressure checked regularly by a healthcare professional. High blood pressure is a particular concern if you're black because it's more prevalent among blacks than any other group in the United States. Research from Johns Hopkins University found that a primary cause of high blood pressure among blacks was stress. However, anyone can develop high blood pressure. When you have a blood pressure check: The first, or top, number in the reading is called the systolic number; the second, or lower, number, is the diastolic number. Normal blood pressure is less than 120 mmHg for systolic pressure and a diastolic level of less ... Read more

Do Marathons' Road Closures Lead to More Local Deaths?

Posted 14 days ago by Drugs.com

WEDNESDAY, April 12, 2017 – When a marathon shuts down city streets, it's more than an inconvenience: Nearby residents appear more likely to die from heart attack and cardiac arrest, a new study finds. The study, of 11 U.S. cities, found that older residents were less likely to survive the heart events on marathon days, compared to other days, perhaps due to delays in receiving care. Older people who landed in the hospital on a race day were over 13 percent more likely to die within a month, the findings showed. There was a similar difference when researchers compared those patients with older adults admitted the same day to hospitals outside the marathon-affected areas. The study drew praise but also notes of caution. "This is a great study," said Dr. Howard Mell, a spokesman for the American College of Emergency Physicians. When a city hosts a major sports event, he said, organizers ... Read more

Trans Fat Bans May Have Cut Heart Attack, Stroke Rate

Posted 14 days ago by Drugs.com

WEDNESDAY, April 12, 2017 – Could the contents of your cupcake affect your heart attack risk? It seems so, according to a new study that found lower rates of heart attack and stroke in communities that restrict trans fats in foods. Trans fats, which are found in products such as baked goods, chips, crackers and fried foods, have been linked to an increased risk of heart disease. In response, some U.S. cities have implemented policies to reduce trans fats in restaurant food. "Our study highlights the power of public policy to impact the cardiovascular health of a population. Trans fats are deleterious for cardiovascular health, and minimizing or eliminating them from the diet can substantially reduce rates of heart attack and stroke," said study author Dr. Eric Brandt. He's a clinical fellow in cardiovascular medicine at the Yale School of Medicine. The researchers compared 2002-13 data ... Read more

Exercisers May Have Better Shot of Surviving Heart Attack

Posted 14 days ago by Drugs.com

WEDNESDAY, April 12, 2017 – Maybe this will be the news that finally jolts you off the couch and into an exercise program. A new study suggests that being physically active increases the chances of survival after a heart attack. Researchers compared exercise levels among 1,664 heart attack patients in Denmark, including 425 who died immediately. Those who had been physically active were less likely to die, and the risk of death decreased as exercise levels rose. Patients who had light or moderate/high physical activity levels were 32 percent and 47 percent less likely to die from their heart attack, respectively, than the sedentary patients. The study was published April 12 in the European Journal of Preventive Cardiology. "We know that exercise protects people against having a heart attack," said study co-author Eva Prescott, a professor of cardiovascular prevention and rehabilitation ... Read more

The Grayer His Hair, the Higher His Heart Risk?

Posted 16 days ago by Drugs.com

MONDAY, April 10, 2017 – Beyond signaling the march of time, gray hair may also point to a higher risk of heart disease for men, new research suggests. But don't panic if you sport silvery locks – the study only showed an association, not a cause-and-effect link, between hair color and heart risks. The finding stems from an analysis that looked at 545 adult men for signs of heart trouble, and then cross-referenced the results with hair color. "In our population, a high hair-whitening score was associated with an increased risk of atherosclerotic coronary artery disease," said study author Irini Samuel. She is a cardiologist at Cairo University, in Egypt. Atherosclerosis refers to the build-up of plaque in the arteries. Samuel said the finding held up regardless of a man's age or whether or not he was already known to face a high risk for developing heart disease. The frequency with ... Read more

Who Really Needs Blood Pressure, Cholesterol Meds?

Posted 20 days ago by Drugs.com

THURSDAY, April 6, 2017 – High blood pressure and high cholesterol are known risk factors for heart attacks and strokes, but it's unclear who needs medication to help manage these conditions, a new report suggests. According to a new Consumer Reports review, patients should consider these factors when deciding whether to take medications: Weigh your risk. Everyone aged 40 and older should be aware of their 10-year risk for heart attack or stroke. Ideally, it should be less than 7.5 percent. Consumer Reports recommends using a calculator developed by the American College of Cardiology and the American Heart Association to determine your risk. Don't rush to medicate. Some lifestyle changes may be enough to manage slightly elevated blood pressure and cholesterol levels. Exercise alone can significantly improve blood pressure, the review noted. Get the right drug.

Heart Devices 101: Guide to the Tools That Keep You Ticking

Posted 3 Apr 2017 by Drugs.com

SUNDAY, April 2, 2017 – Pacemakers, defibrillators and other medical devices have saved the lives of millions of people worldwide. Someone you know probably has received one of these heart-health enhancers, although not all have become household words. The U.S. Food and Drug Administration evaluates and regulates these and other medical devices in the United States. Below, the agency provides a brief glossary of terms that might come in handy when a doctor recommends a cardiac tool: Heart pacemakers: These small, battery-powered devices are implanted in the body. They deliver an electric shock to restore normal heart rhythm when the heart beats too slowly. Implantable cardioverter defibrillators: These deliver a shock to restore normal heart rhythm when the heart beats too fast. Automated external defibrillators: These portable, automatic devices are found in many public locations. ... Read more

When Heart Stops Beating, Survival Better at Specialized Heart Centers

Posted 29 Mar 2017 by Drugs.com

WEDNESDAY, March 29, 2017 – Getting immediate treatment at a specialized heart center – rather than the nearest local hospital – improves your chance of survival if your heart stops beating, a new study suggests. Researchers reviewed data from more than 41,000 people in Denmark. All of them had cardiac arrest – which means their hearts suddenly stopped beating – between 2001 and 2013. None were in a hospital when their cardiac arrest happened. Of those patients, 29 percent were admitted directly to a specialized heart center. The rest were taken to a local hospital. Nine percent of patients were still alive after 30 days. The researchers calculated that those patients who were immediately taken to a specialized heart center were 11 percent more likely to be alive after 30 days than those taken to a local hospital. The distance someone had to travel to get to a specialized heart ... Read more

ATMs, Coffee Shops Ideal Spots for Heart Defibrillators

Posted 20 Mar 2017 by Drugs.com

MONDAY, March 20, 2017 – ATMs and coffee shops may be among the best spots to place lifesaving defibrillators, a new study suggests. Automated external defibrillators (AEDs) are devices that can be used by a layperson to restart the heart of someone in cardiac arrest. But to do that, they have to be readily accessible. The new study tried to locate where AEDs could potentially save the most lives. Focusing on Toronto, the Canadian researchers found that many of the city's cardiac arrest emergencies happened near coffee shop chains, such as Tim Hortons and Starbucks, and ATMs connected to large banks. In fact, those businesses accounted for eight of the top 10 hot spots. While the study looked only at Toronto, lead researcher Timothy Chan thinks the findings would likely extend to other cities. Both ATMs and chain coffee shops are ubiquitous, said Chan, who directs the University of ... Read more

Health Tip: Resuming Activities After a Heart Attack

Posted 9 Mar 2017 by Drugs.com

-- Life after a heart attack may seem uncertain, and you may be anxious to get back to your regular activities. The American Academy of Family Physicians advises: Talk to your doctor about specific activities, and when it is safe to resume them. The amount of time needed before returning to work depends on your job. You may need to adjust your work and schedule. It's typically safe to drive again about a week after your heart attack, but check with your doctor. Also, ask your doctor about when to resume intimacy. Go slowly and allow yourself time to heal. Make lifestyle changes that could speed your recovery. Read more

Impotence Meds Might Give Men's Hearts a Boost, Too

Posted 9 Mar 2017 by Drugs.com

THURSDAY, March 9, 2017 – Men taking Viagra, Levitra or Cialis to revitalize their sex life might experience a valuable side benefit: enhanced heart health, researchers say. Those erectile dysfunction drugs, called PDE5 inhibitors, appear to reduce a man's risk of death or heart failure after a first heart attack, according to preliminary study findings. Men taking this type of ED drug had a 33 percent reduced risk of death within three years of their first heart attack, compared to men not taking the PDE5 inhibitor, said lead researcher Dr. Daniel Andersson. The men also experienced a 40 percent reduced risk of subsequent hospitalization for heart failure, said Andersson, a postdoctoral researcher at the Karolinska Institute in Sweden. Further, it appeared that taking more of the drug increased the survival advantage, he added. "We also find a dose-dependent relationship between ... Read more

Cholesterol's Impact on Heart Attack Risk May Change With Age

Posted 8 Mar 2017 by Drugs.com

WEDNESDAY, March 8, 2017 – Cholesterol's impact on heart attack may differ by age, new research suggests. The study found that younger heart attack patients are much more likely to have significantly low levels of HDL ("good") cholesterol, rather than high levels of LDL ("bad") cholesterol. The findings might help doctors pinpoint which of their younger patients are in need of cholesterol-lowering therapies, the researchers said. "We . . . want to look at prescribing patterns for statins in younger patients who are at increased risk for heart disease," said study lead author Bradley Collins, a fourth-year student at Harvard Medical School. "Ultimately, we would like to develop new tools for calculating heart attack risk that are more applicable to younger people," Collins said in a news release from the American College of Cardiology (ACC). Most people who get their cholesterol checked ... Read more

Poor Diet Tied to Half of U.S. Deaths From Heart Disease, Diabetes

Posted 7 Mar 2017 by Drugs.com

TUESDAY, March 7, 2017 – Nearly half of all deaths from heart disease, stroke and diabetes in the United States are associated with diets that skimp on certain foods and nutrients, such as vegetables, and exceed optimal levels of others, like salt, a new study finds. Using available studies and clinical trials, researchers identified 10 dietary factors with the strongest evidence of a protective or harmful association with death due to "cardiometabolic" disease. "It wasn't just too much 'bad' in the American diet; it's also not enough 'good,'" said lead author Renata Micha. "Americans are not eating enough fruits, vegetables, nuts/seeds, whole grains, vegetable oils or fish," she said. Micha is an assistant research professor at the Tufts University School of Nutrition Science and Policy in Boston. The researchers used data from multiple national sources to examine deaths from ...

Would You Feel Safe in a Driverless Ambulance?

Posted 7 Mar 2017 by Drugs.com

MONDAY, March 6, 2017 – Automated, driver-free cars and trucks may be the wave of the future. But new research suggests many Americans aren't sold on the idea of a ride in a driverless ambulance. This new technology does have one potential advantage over current emergency vehicles. Right now, a patient in an ambulance gets medical attention only from one paramedic, while the other crew member drives the vehicle. But "an automated ambulance would allow patients to get to the hospital much more quickly and smoothly while receiving care from two providers instead of one," said study co-author Joseph Keebler. "Automation could be especially important in many regions where emergency medical services are insufficiently funded," added Keebler, who is an assistant professor of human factors at Embry-Riddle Aeronautical University in Daytona Beach, Fla. And with prototype driverless cars and ... Read more
