'Stress Ball' in Your Brain May Be Key to Heart Risks

Posted 10 days ago by Drugs.com

WEDNESDAY, Jan. 11, 2017 – Doctors have long known that a stressed life does no favors for the heart, and new research may help unravel why that's so. A Harvard team says heightened activity in a key part of the brain may explain why stress boosts people's odds for heart disease and stroke. The finding "raises the possibility that reducing stress could produce benefits that extend beyond an improved sense of psychological well-being," said study lead author Dr. Ahmed Tawakol, who co-directs the cardiac imaging program at Massachusetts General Hospital in Boston. One neurologist agreed that the research could have real value for patients. "This study provides information that can help us better understand the mechanisms in which the body and the brain affect each other," said Dr. Jeffrey Borenstein. He is president of the Brain & Behavior Foundation in New York City. "A better ... Read more

Blood Levels of Meat-Linked Chemical Tied to Odds of Heart Trouble

Posted 11 days ago by Drugs.com

WEDNESDAY, Jan. 11, 2017 – A molecule produced in the digestion of red meat, eggs and dairy products is linked to an increased risk of a fatal heart attack or stroke, researchers say. Patients with high blood levels of trimethylamine N-oxide (TMAO) were six times more likely within the next month to die, suffer a heart attack or stroke, or require surgery to reopen a blocked artery, according to the study. TMAO also predicted long-term health risks, researchers said. People with the highest blood levels of TMAO were nearly twice as likely to die within seven years. "A high TMAO level predicted who went on to experience a major cardiovascular event," said lead researcher Dr. Stanley Hazen, chair of cellular and molecular medicine at the Cleveland Clinic's Lerner Research Institute. TMAO is produced by gut bacteria during digestion of animal-based food, and accumulates in blood plasma, ... Read more

High Blood Pressure Increasing Worldwide

Posted 12 days ago by Drugs.com

TUESDAY, Jan. 10, 2017 – As the number of people around the world with elevated or high blood pressure increases, so do the number of deaths linked to this "silent killer," a new study contends. An international analysis of nearly 9 million people states that the rate of high blood pressure (hypertension) and elevated blood pressure (prehypertension) jumped between 1990 and 2015. "There are almost 900 million people in the world with hypertension, and there are almost 3.5 billion people with elevated blood pressure that doesn't quite meet the definition of hypertension," said study lead author Christopher Murray. He directs the University of Washington's Institute for Health Metrics and Evaluation in Seattle. "Blood pressure is the leading cause of premature death and disability in the world," Murray said. Blood pressure is made up of two numbers. The top number, called systolic ... Read more

Study Ties Alcohol Abuse to Increased Heart Risks

Posted 20 days ago by Drugs.com

MONDAY, Jan. 2, 2017 – A new study suggests that people who abuse alcohol also boost their risk of three cardiac conditions: atrial fibrillation, heart attack and congestive heart failure. The possible added risk appears to be about the same as that linked to high blood pressure, smoking, obesity and diabetes, the researchers said. "We found that even if you have no underlying risk factors, abuse of alcohol still increases the risk of these heart conditions," lead researcher Dr. Gregory Marcus said in an American College of Cardiology news release. Marcus is director of clinical research at the University of California, San Francisco's division of cardiology. The study was based on a database of close to 15 million Californians aged 21 and older who had outpatient surgery, emergency room treatment or inpatient hospital care between 2005 and 2009. About 2 percent had been diagnosed with ... Read more

On Hospital Wards, Patient Crises May Have 'Domino Effect'

Posted 27 Dec 2016 by Drugs.com

TUESDAY, Dec. 27, 2016 – Hospitalized patients have a higher risk of cardiac arrest and transfers to intensive care if they're in wards when other patients have recently suffered similar emergencies, a new study suggests. "This should serve as a wake-up call for hospital-based physicians," study author Dr. Matthew Churpek, an assistant professor of medicine at the University of Chicago, said in a university news release. "After caring for a patient who becomes critically ill on the hospital wards, we should routinely check to see how the other patients on the unit are doing," he said. "Following these high-intensity events, our to-do list should include a thorough assessment of the other patients on the unit, to make sure none of them are at risk of slipping through the cracks," he added. Churpek's team tracked outcomes for adult patients who were admitted to the University of Chicago ... Read more

Women Chasing Holiday Perfection May Miss Signs of Heart Trouble

Posted 23 Dec 2016 by Drugs.com

FRIDAY, Dec. 23, 2016 – Holiday pressure can stress anybody out, but some women get so anxious about making everything perfect that they miss the signs of serious heart problems. One of those threats is a so-called "silent heart attack." "Most of the time people who are experiencing a heart attack will have pain in the chest, shortness of breath, etc. Silent heart attack symptoms might be as simple as indigestion, flu-like symptoms, or feeling discomfort like a pulled muscle in the chest or back," said Dr. Karla Kurrelmeyer, a cardiologist at Houston Methodist DeBakey Heart & Vascular Center. It's important to have these symptoms checked as soon as possible to avoid scarring or damage to the heart, she said in a hospital news release. Another condition, known as stress-induced cardiomyopathy, can strike women when they're under great stress and hit with a traumatic life event like the ... Read more

Is Season the Reason Why Heart Deaths Spike at Christmas?

Posted 23 Dec 2016 by Drugs.com

THURSDAY, Dec. 22, 2016 – It's not the chill of winter that causes a spike in heart-related deaths at Christmas and New Year's – it's the holiday season itself, Australian researchers contend. In New Zealand, where December and January are the height of summer, researchers found more than a 4 percent increase in heart-related deaths from Dec. 25 through Jan. 7. "The Christmas effect that has been seen in the northern hemisphere winter is able to be seen during the summer also," said lead researcher Josh Knight, a research fellow at the University of Melbourne. "This means that there is a risk associated with the holiday period independent of the seasonality," he said. Exactly why the holidays are linked with a boost in heart-related deaths is open to debate. "There are likely to be two separate populations who are combining to create the Christmas effect," Knight said. One is people ... Read more

High Pain Tolerance Tied to 'Silent' Heart Attack Risk

Posted 22 Dec 2016 by Drugs.com

WEDNESDAY, Dec. 21, 2016 – People who are less sensitive to pain may be at increased risk of having a "silent" heart attack, a new study hints. Chest pain is one of the "classic" symptoms of a heart attack. But many people have so-called silent heart attacks, where they notice no obvious symptoms. "Almost everyone knows what a heart attack is. When we hear about it, we think of chest pain and [emergency] medical care," said Dr. Andrea Ohrn, the lead researcher on the new study. "But what's less known is, many people experience heart attacks without knowing it – without ever receiving a diagnosis," said Ohrn, a fellow at the University of Tromso in Norway. No one knows why that is. But the new findings suggest that pain tolerance might be a factor. Using a standard test of pain sensitivity, Ohrn's team found that people who had a silent heart attack in the past generally had a higher ... Read more

HIV May Double Odds of Heart Attack

Posted 22 Dec 2016 by Drugs.com

WEDNESDAY, Dec. 21, 2016 – As people with HIV are living longer, new concerns are cropping up, such as a risk for heart attack up to two times greater than for people without the AIDS-causing virus, a new study reports. Those increased odds are seen even in people whose virus has been suppressed to undetectable levels in the blood with antiretroviral drugs, the researchers said. There are several reasons for this higher risk, said lead researcher Dr. Matthew Feinstein, a cardiology fellow at Northwestern University Feinberg School of Medicine in Chicago. "A key factor appears to be chronic HIV-associated inflammation that persists even when there is no detectable virus in the blood," he said. Feinstein explained that the heart disease and stroke risk is higher "because the virus maintains a reservoir in the body's tissues, driving a chronic inflammatory and immune response that can ...

Quick Shot of Epinephrine Boosts Cardiac Arrest Patients' Survival: Study

Posted 6 Dec 2016 by Drugs.com

TUESDAY, Dec. 6, 2016 – Cardiac arrest patients who receive epinephrine (adrenaline) within five minutes of their heart stopping are more likely to survive than those who don't receive the drug within that time frame, according to a new study. Researchers analyzed outcomes among more than 100,000 patients who suffered cardiac arrest while staying at nearly 550 hospitals across the United States. Cardiac arrest occurs when the heart suddenly stops beating, while a heart attack happens when blood flow to the heart is blocked and heart tissue is damaged. In the study, survival rates were nearly 13 percent among patients who received epinephrine shots within five minutes of their heart stopping. Rates were only 11 percent among those who received the drug after five minutes had passed. "That is a 20 percent better survival rate for patients at hospitals where epinephrine is given quickly, ... Read more

After Cancer, Higher Risk of Severe Heart Attack

Posted 1 Dec 2016 by Drugs.com

THURSDAY, Dec. 1, 2016 – Cancer survivors are at increased risk for the most severe type of heart attack and require close attention to their heart health, a new study suggests. Researchers at the Mayo Clinic in Rochester, Minn., reviewed data on more than 2,300 patients who suffered this type of heart attack, called ST-elevation myocardial infarction (STEMI). One in 10 had a history of cancer, the investigators found. "We've watched cancer survivorship increase over the past two-and-a-half decades, which is wonderful. But, it has led to new challenges, such as handling of downstream illnesses and side effects to an extent never encountered before," said study senior author Dr. Joerg Herrmann. He is an interventional cardiologist at the clinic. "As cardiologists, we wanted to know if cancer and its therapies left these patients debilitated from a cardiovascular disease standpoint," he ...

Smoking Raises Heart Attack Risk 8-Fold in People Under 50

Posted 30 Nov 2016 by Drugs.com

TUESDAY, Nov. 29, 2016 – All smokers face a higher risk of heart attack, but the threat is particularly high among those under 50, a new study finds. Compared to former smokers and nonsmokers in their age group, heart attack risk was nearly 8.5 times higher for smokers younger than 50, British researchers found. One expert in smoking and health who reviewed the report said the findings underline the importance of keeping youth and cigarettes apart. "Through comprehensive tobacco-control programs that include environmental smoking bans, high taxes on cigarettes, and anti-tobacco media campaigns, we can decrease the rates of smoking/tobacco use, heart disease and many other health conditions," said Patricia Folan. She directs the Center for Tobacco Control at Northwell Health in Great Neck, N.Y. The study found that smokers at older ages faced higher heart risks, as well. Compared to ... Read more

Many Women With Chronic Ills Don't Use Online Tools

Posted 28 Nov 2016 by Drugs.com

MONDAY, Nov. 28, 2016 – Chronically ill women who don't use the internet may struggle with worse health, a new study finds. "A significantly larger proportion of non-internet users reported needing help learning what to do to manage their health conditions and needing help learning how to care for their health conditions," said researcher Carolyn Mendez-Luck. She's an assistant professor in the School of Social and Behavioral Health Sciences at Oregon State University. She and her colleagues analyzed information provided by hundreds of American women aged 44 and older with at least one chronic condition. These included heart disease, cancer, stroke, diabetes, arthritis, asthma, emphysema and anxiety. More than one-third didn't use the internet. And fewer than half of those who did have access used the web to learn from others with a chronic disease, the researchers found. Also, fewer ... Read more

Amputations Due to Poor Blood Flow More Likely in Certain Groups

Posted 18 Nov 2016 by Drugs.com

FRIDAY, Nov. 18, 2016 – Poor and black patients with narrowing of the blood vessels have a higher risk of amputation than other patients, a new study finds. Peripheral artery disease (PAD), as this blood-vessel narrowing is called, develops when fat, cholesterol and other substances accumulate in blood vessels away from the heart and restrict blood flow. It typically occurs in the legs. Besides increasing the risk for heart attack and stroke, untreated peripheral artery disease can lead to tissue death ("gangrene") that results in amputation, the study authors explained. For this study, researchers analyzed data from more than 208,000 U.S. veterans with the disease. The investigators found that black patients had a 43 percent higher risk of amputation than white patients in the same socioeconomic group. And poor patients had a 37 percent increased risk of amputation, regardless of ... Read more

Heart Attacks Up in New Orleans Post-Katrina

Posted 18 Nov 2016 by Drugs.com

FRIDAY, Nov. 18, 2016 – A major New Orleans hospital has seen a sharp spike in the rate of heart attacks in the 10 years since Hurricane Katrina devastated the city, a new study reports. Heart attack admissions to Tulane Medical Center were three times higher during the 10 years after the hurricane struck in August 2005 than in the two years before that, according to researchers. "Although the general emphasis after an event such as Katrina is on rebuilding, we should not neglect the health of those affected by a disaster," said lead author Dr. Anand Irimpen. He's a professor of medicine at Tulane University School of Medicine and chief of cardiology at Southeast Louisiana Veterans Health Care System in New Orleans. The study included 150 records from heart attack patients seen at Tulane Medical Center in the two years leading up to Katrina, and more than 2,300 records from heart ... Read more
