When Oxygen Runs Low, the Naked Mole-Rat Finds a Way

Posted 2 days 22 hours ago by Drugs.com

THURSDAY, April 20, 2017 – When brain cells are starved of oxygen, people and all other mammals run out of energy and begin to die. Not so for a hairless, underground rodent called the naked mole-rat. It survives low-oxygen conditions because its brain cells switch from using glucose as fuel to fructose – a process that is typically found in plants, not animals. Scientists believe their new findings could someday lead to new treatments for people who have a heart attack or stroke. "This is just the latest remarkable discovery about the naked mole-rat – a cold-blooded mammal that lives decades longer than other rodents, rarely gets cancer and doesn't feel many types of pain," said the study's leader, Thomas Park. He is a professor of biological sciences at the University of Illinois at Chicago. The naked mole-rat is native to Africa and lives in extensive underground burrows. In the ... Read more

Many Heart Attack Patients Fail to Stick With Statins

Posted 4 days ago by Drugs.com

WEDNESDAY, April 19, 2017 – High doses of powerful statin drugs have been shown to avert future heart problems, including heart attack and stroke. Yet many heart attack patients stop taking these medicines as recommended, a new study reveals. Researchers examined data for heart attack patients who had a prescription for a "high-intensity" statin filled within 30 days of being discharged from the hospital. Two years later, only 42 percent were taking these medicines regularly, the study found. Thirteen percent switched to a low- or moderate-intensity statin, while 19 percent weren't taking a statin regularly. Close to 1 in 5 stopped taking any statin altogether, the researchers said. The lack of adherence to recommended high-intensity statin therapy is short-sighted, suggested study lead author Dr. Robert Rosenson. "The message is that the benefits of statins continue to accrue over ... Read more

Blood Pressure: Know Your Numbers

Posted 5 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

Another Downside to Unemployment: Stroke Risk?

Posted 10 days ago by Drugs.com

THURSDAY, April 13, 2017 – Losing a job might increase your risk for a fatal stroke, a new study from Japan suggests. "While the Japanese culture is different from the U.S. culture, the implication is that job security could help reduce stroke risk," said lead researcher Dr. Ehab Eshak. Eshak is a visiting associate professor of public health at Osaka University's Graduate School of Medicine. Among roughly 42,000 Japanese adults, Eshak's team found that those who remained employed over 15 years had a lower risk of stroke than those who lost a job. Compared with steadily employed workers, jobless men had a nearly 60 percent higher risk of stroke. And they were 120 percent more likely to die from it, Eshak said. Women with a jobless stint suffered, too. They were over 50 percent more likely to have a stroke and nearly 150 percent more likely to die from it, the study found. Stroke – ... Read more

Many Americans Don't Know How to Handle High Cholesterol

Posted 12 days ago by Drugs.com

TUESDAY, April 11, 2017 – Americans with high cholesterol are well aware of its heart dangers, but many lack the confidence or knowledge to keep it under control, a new survey shows. High cholesterol is a risk factor for heart disease and stroke, causing about 2.6 million deaths in the United States each year, the researchers said. The survey included nearly 800 people nationwide with either a history of heart disease or at least one major risk factor for heart disease and stroke, such as high cholesterol, high blood pressure or diabetes. Overall, 47 percent of the respondents had not had their cholesterol checked in the past year. While those with high cholesterol had higher rates of recent testing, 21 percent of them had not had their cholesterol checked in the past year. Eighty-two percent of the respondents knew there was a link between cholesterol and risk for heart disease and ... Read more

More Younger Americans Are Suffering Strokes: Study

Posted 13 days ago by Drugs.com

MONDAY, April 10, 2017 – Strokes are typically associated with the elderly, but new research suggests that strokes are increasingly happening to Americans under 65. The study looked at a sample of data from some U.S. stroke hospitalizations. From 2003 to 2004 in this sample, more than 141,000 people from 18 to 65 were admitted to hospitals for stroke. By 2011 to 2012, that number had risen to more than 171,000, researchers found. "Our results stress the importance of prevention of stroke risk factors in younger adults," said lead author Dr. Mary George. She's a senior medical officer with the U.S. Centers for Disease Control and Prevention's division of heart disease and stroke prevention. "Young adults, ages 18 to 54, are experiencing a small but sustained increase in stroke and in the prevalence of traditional stroke risk factors, such as high blood pressure, diabetes, high ...

Who Really Needs Blood Pressure, Cholesterol Meds?

Posted 17 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.

Fitness, Not Fat, Is Key to Post-Stroke Recovery

Posted 18 days ago by Drugs.com

WEDNESDAY, April 5, 2017 – People who were active and exercised regularly before their stroke were less likely to face disability after the attack, researchers say. But the amount of body fat a person had did not seem to be tied to post-stroke disability, the study found. Fitness was key, though. "Being physically inactive before stroke predicts a higher risk of being dependent both before and after stroke," said study author Pamela Rist, of Harvard University. Her team's findings were published online April 5 in the journal Neurology. The new study involved more than 18,000 people with no history of stroke who were followed for an average of 12 years. During that time, nearly 1,400 of the participants suffered a stroke but survived. Three years after their stroke, those who had exercised regularly before their stroke were 18 percent more likely to be able to perform basic tasks – ... Read more

For Firefighters, Another Danger: The Heart

Posted 20 days ago by Drugs.com

MONDAY, April 3, 2017 – Intense heat and strain appear to put firefighters at a greater risk of heart attack, a new study finds. The physical demands of firefighting may trigger the formation of blood clots and impair blood vessel function – two factors associated with increased risk of heart attack and stroke, researchers in Scotland report. Their report helps explain why heart disease is the leading cause of death among "the bravest," as they're known. In the United States, heart disease accounts for nearly half of annual on-duty firefighter fatalities, most of them from heart attack, said Dr. Nicholas Mills, lead researcher on the study. Mills is chair of cardiology at the University of Edinburgh. In simulated fire exercises, the investigators sought to quantify the physiological changes firefighters undergo as they rescue a victim from a scorching building. "We discovered the core ...

Exercise a Great Prescription to Help Older Hearts

Posted 24 Mar 2017 by Drugs.com

THURSDAY, March 23, 2017 – Regular exercise is potent medicine for older adults with heart disease, a new American Heart Association scientific statement says. Physical activity should be a key part of care for older adults with heart disease who want to reduce their symptoms and build their stamina, said geriatric cardiologist Dr. Daniel Forman. He's chair of the panel that wrote the new statement. "Many health-care providers are focused only on the medical management of diseases – such as heart failure, heart attacks, valvular heart disease and strokes – without directly focusing on helping patients maximize their physical function," Forman said in a heart association news release. Yet, after a heart attack or other cardiac event, patients need to gain strength. Their independence may require the ability "to lift a grocery bag and to carry it to their car," said Forman, a professor ... Read more

Are Blood Thinners Overused in Patients With Irregular Heartbeat?

Posted 17 Mar 2017 by Drugs.com

FRIDAY, March 17, 2017 – Many people living with the heart rhythm disorder known as atrial fibrillation may be taking unneeded blood thinners, a new study suggests. These blood thinners, which include aspirin, Plavix and warfarin, are believed to reduce the risk of stroke that can come with atrial fibrillation. But for many atrial fibrillation patients with a low stroke risk, the medications might actually increase both bleeding and stroke risk, researchers reported. The way most doctors decide whether a patient needs a blood thinner is by using a simple score called CHADS2, which assigns points to patients based on age and other medical risks. A score of 2 is usually needed to recommend a blood thinner, the researchers explained. But, "people are realizing that the CHADS2 scores are putting too many people above the threshold – it's pretty easy to get a 2," explained study author ... Read more

Many With Irregular Heartbeat Not on Meds They Need: Study

Posted 14 Mar 2017 by Drugs.com

TUESDAY, March 14, 2017 – Many people with an irregular heartbeat who suffer a stroke may not have been on medications that might have prevented their stroke, a new study suggests. Duke University researchers found that 84 percent of stroke patients with the heart condition known as atrial fibrillation (AF) had not been getting adequate clot-preventing therapy. Dr. David Wilber, a cardiologist at Loyola University Medical Center in Illinois, called the findings "sobering." "This emphasizes the fact that probably the most important cause of stroke in AF patients is under-anticoagulation or no anticoagulation," said Wilber, who is also editor-in-chief of the journal JACC: Clinical Electrophysiology. Study lead researcher Dr. Ying Xian agreed. "We estimate that the vast majority of these strokes could have been prevented if patients had the appropriate anticoagulation," said Xian, an ...

Failed Fertility Treatments, Poorer Heart Health Later?

Posted 13 Mar 2017 by Drugs.com

MONDAY, March 13, 2017 – Women who undergo fertility treatment but don't get pregnant may have a slightly higher risk of heart disease, a new study suggests. Failed fertility therapy was linked to a 19 percent increased risk of heart attack, stroke or heart failure later in life among the women in the study, said lead researcher Dr. Jacob Udell. He is a cardiologist at Women's College Hospital in Toronto. "Two-thirds of women were unsuccessful after undergoing fertility treatment, and it was in those women we found an association with an increased risk in adverse cardiovascular events long-term," Udell said. But the study did not prove a cause-and-effect link between the two. Udell said he and his colleagues conducted this research after noticing that fertility drug treatments can create short-term complications, including high blood pressure and diabetes – conditions linked to ...

Fish Oil Pills May Help After Heart Attack, Specialists Say

Posted 13 Mar 2017 by Drugs.com

MONDAY, March 13, 2017 – Doctors may want to consider prescribing fish oil pills to heart attack survivors and patients with chronic heart failure, new recommendations from the American Heart Association suggest. Fish oil may help extend the lives of those patients, the heart association said. On the other hand, the supplements cannot be recommended for preventing heart problems in the first place, said Dr. David Siscovick, lead author of the report. That's because no clinical trials have tested fish oil's effects in people who are free of heart disease. Meanwhile, a few trials have given fish oil to people at increased risk of heart disease – because of diabetes or high cholesterol, for example. All but one has come up empty. "Many people take fish oil hoping to prevent heart disease," Siscovick acknowledged. "But there's a lack of evidence that it does." Fish oil is rich in omega-3 ... Read more

Severe Low Blood Sugar Episode May Up Death Risk in Those With Type 2 Diabetes

Posted 11 Mar 2017 by Drugs.com

FRIDAY, March 10, 2017 – Just one episode of dangerously low blood sugar might increase the risk of death, heart disease and stroke in people with type 2 diabetes, a new study suggests. The low blood sugar (hypoglycemia) episode had to be so serious that it required a visit to the emergency room, according to researchers from Johns Hopkins Bloomberg School of Public Health in Baltimore. "If you have a patient with a history of severe hypoglycemia, this could portend poorly for his or her future," said study co-author Alexandra Lee, a Ph.D. candidate in epidemiology. "Our thinking has been that you resolve a hypoglycemic episode and it's over. But what this tells us is that one episode may have long-lasting consequences," Lee said in a school news release. However, the researchers also noted that it's not clear from this study whether people who had a severe low blood sugar episode were ... Read more
