Regional Systems to Treat Severe Heart Attack Increasing

Posted 4 days ago by Drugs.com

WEDNESDAY, May 23 – The number of regional care systems able to quickly identify, transfer if necessary, and treat patients experiencing the most severe form of heart attack is increasing, new research finds. ST-segment elevation myocardial infarction, or STEMI, is a deadly form of heart attack that affects nearly 300,000 people in the United States per year. It occurs when a blood clot completely blocks an artery to the heart. Quickly restoring blood flow is needed in order to prevent death. In a regional STEMI-care system, emergency medical services have the equipment on their ambulances to diagnose the heart attack on the way to the hospital, and hospitals cooperate to make sure that patients are delivered to a facility that can quickly activate a team able to treat the heart attack. That treatment is often the artery-opening procedure called percutaneous coronary intervention, ... Read more

Living Near Major Roads May Shorten Heart Attack Survival

Posted 7 May 2012 by Drugs.com

MONDAY, May 7 – A new study finds that heart attack survivors who live close to major roads are at increased risk for death from all causes during a 10-year span. U.S. researchers looked at more than 3,500 heart attack survivors with an average age of 62 and found that those who lived less than about 330 feet from a major road were 27 percent more likely to die over 10 years than those who lived about 3,300 feet or more away. Patients who lived about 330 to 650 feet away from a major road had a 19 percent increased risk of death, and those who lived about 650 to 3,300 feet away had a 13 percent increased risk of death. The roads in the study included major interstate and state highways throughout the United States. There were nearly 1,100 deaths during the 10-year study, 63 percent from cardiovascular causes, 12 percent from cancer and 4 percent from respiratory disease. The findings ... Read more

Heart Attack Survival Varies Widely Among Hospitals, Study Finds

Posted 1 May 2012 by Drugs.com

MONDAY, April 30 – The odds you'll survive a heart attack vary widely depending on where you're treated in the United States, according to a new study by Yale University researchers. Hospitals that follow five simple strategies – including good teamwork and having cardiologists on hand 24/7 – have twice the 30-day survival rates of other medical centers, the study found. But fewer than 10 percent of the 500-plus U.S. hospitals studied follow even four of the five practices, the study authors said. "If we could implement all of the strategies across the nation, we would save thousands of lives annually," said lead researcher Elizabeth Bradley, a professor of public health at the Yale School of Public Health in New Haven, Conn. "Relatively simple strategies and a culture that focuses not on hiding problems but on finding and solving problems is the best medicine we can give ourselves." ... Read more

Researchers Repair Damage Caused by Heart Attacks in Mice

Posted 18 Apr 2012 by Drugs.com

WEDNESDAY, April 18 – Scientists report they were able to repair mouse hearts that were damaged by heart attacks. Researchers from the Gladstone Institutes successfully converted scar tissue in the mice into beating heart muscle. Their findings, they said, might eventually lead to a similar treatment for people who've had heart attacks. "The damage from a heart attack is typically permanent because heart-muscle cells – deprived of oxygen during the attack – die and scar tissue forms," Dr. Deepak Srivastava, who directs cardiovascular and stem cell research at Gladstone, a nonprofit biomedical research institution, said in a Gladstone news release. "But our experiments in mice are a proof of concept that we can reprogram non-beating cells directly into fully functional, beating heart cells – offering an innovative and less invasive way to restore heart function after a heart attack." ...

Optimism Might Cut Your Risk for Heart Attack

Posted 18 Apr 2012 by Drugs.com

WEDNESDAY, April 18 – Being upbeat is good for your heart, a new study suggests. Many previous studies have shown that negative mental states – such as depression, anger, anxiety and hostility – can harm the heart. This Harvard School of Public Health review of more than 200 studies found that positive feelings appear to reduce the risk of cardiovascular disease and events such as heart attack and stroke. "The absence of the negative is not the same thing as the presence of the positive," lead author Julia Boehm, a research fellow in the department of society, human development, and health, said in a university news release. "We found that factors such as optimism, life satisfaction and happiness are associated with reduced risk of [cardiovascular disease] regardless of such factors as a person's age, socioeconomic status, smoking status or body weight." "For example, the most ... Read more

Omega-3 Supplements No Help Against Repeat Heart Trouble: Review

Posted 9 Apr 2012 by Drugs.com

MONDAY, April 9 – Taking omega-3 fatty acid supplements won't protect against repeat heart attacks, strokes or other cardiovascular problems, a new analysis indicates. "I was not surprised at these findings because I assumed that there was no benefit of omega-3 supplements," said lead researcher Dr. Seung-Kwon Myung, chief of the carcinogenesis branch of the National Cancer Center, Republic of Korea. The study is published online April 9 in the Archives of Internal Medicine. Instead of taking supplements, people trying to prevent heart disease or repeat problems should eat oily fish such as salmon, tuna and mackerel, which are all rich in omega-3 fatty acids, Myung said. "It is effective against cardiovascular disease to eat fish rich in omega-3 fatty acids, not supplements," he said. Many studies have demonstrated that eating fatty fish two or more times a week is linked with a lower ... Read more

Cancer Diagnosis May Raise Odds for Suicide, Heart Attack Death

Posted 4 Apr 2012 by Drugs.com

WEDNESDAY, April 4 – When people learn they have cancer, they might face a heightened risk of suicide or a fatal heart attack in the days and weeks that follow, according to a large new study. Using nationwide census and death registry data that covered more than 6 million people over a 15-year period ending in 2006, Swedish researchers tabulated the suicides and cardiovascular fatalities among people with new cancer diagnoses and compared them to similar deaths in those without cancer. Suicide risk was more than 12 times higher for people with cancer during the first week after diagnosis and nearly five times higher during the first three months, they found. Death from cardiovascular causes – particularly heart attack – was 5.6 times higher in the week after a cancer diagnosis and 3.3 times higher in the first month. Hard-to-treat cancers with poor odds for survival, including ... Read more

Moderate Drinking Might Help Men Live Longer After Heart Attack

Posted 28 Mar 2012 by Drugs.com

WEDNESDAY, March 28 – A drink or two per day may help lower a man's odds of death in the two decades following a heart attack, a new study suggests. The research, which appears online March 28 in the European Heart Journal, included more than 1,800 American men who survived a first heart attack between 1986 and 2006 and were followed for up to 20 years. During that time, 468 of the men died. Men who drank about two alcoholic drinks (between 10 and about 30 grams of alcohol) per day over a long period of time had a 14 percent lower risk of death from any cause, and a 42 percent lower risk of death from cardiovascular disease, than nondrinkers, the study found. For reference, a four-ounce glass of wine contains 11 grams of alcohol, a bottle or can of beer 12.8 grams, and a shot of spirits 14 grams. "Our findings clearly demonstrate that long-term moderate alcohol consumption among men ... Read more

Widespread CPR Training Could Boost Heart Attack Survival Rates

Posted 27 Mar 2012 by Drugs.com

TUESDAY, March 27 --Training more people to perform CPR would significantly improve heart attack survival rates, according to a new study in Denmark, where CPR training is widespread. Researchers analyzed 29,000 cardiac arrests that occurred over the course of a decade and found the proportion of cases involving bystander CPR more than doubled from 20 percent in 2001 to 44 percent in 2010. They also found patients who received CPR or were treated with automated external defibrillators (AEDs) by bystanders before emergency responders arrived were roughly four times more likely to be alive 30 days later than those not helped by bystanders. Cardiac arrest, which occurs when the heart suddenly stops beating, can result from a heart attack or from accidents such as electrocution or drowning. AEDs are machines that can restore normal heart rhythm. "This study is important because it ... Read more

Cardiac Cocktail Delivered by Paramedics May Save Lives

Posted 27 Mar 2012 by Drugs.com

TUESDAY, March 27 – Training paramedics to give probable heart attack patients a mixture of glucose, insulin and potassium may lessen the severity of a heart attack and save lives, new research suggests. When someone suspects a heart attack and dials 911, the responding paramedics will quickly assess whether or not the person is in the throes of having a heart attack, or about to have one. Typically, paramedics will give aspirin to thin the blood and nitroglycerin for chest pain while transporting the patient to the hospital. But the new study indicates that if paramedics administer the glucose/insulin/potassium solution right away, they can reduce the risk of cardiac arrest (when the heart suddenly stops beating) and death by 50 percent. This potentially lifesaving cocktail is readily available and costs just $50, the researchers noted. "It can't stop a heart attack, but it can make ... Read more

Clot-buster Drug Injection Might Help Some Heart Attack Patients

Posted 26 Mar 2012 by Drugs.com

MONDAY, March 26 – Injecting a clot-busting drug directly into a blood clot caused by a certain kind of heart attack seems to save more heart muscle than extracting the clot does, a new study shows. "In the patients who got the antiplatelet agent right in the blood clot, there was a significant reduction in the size of the heart attack," said Dr. Gregg Stone, a professor of medicine at Columbia University Medical Center, in New York City. He led the study, which was presented Sunday at the American College of Cardiology annual meeting in Chicago and published simultaneously in the Journal of the American Medical Association. The researchers looked at 452 patients from 37 sites and six countries who had a heart attack known as a STEMI. Stone called this a "garden-variety" heart attack. The patients in the study all had large STEMI heart attacks, and all arrived for medical care within ... Read more

Both Too Little and Too Much Sleep Bad for the Heart: Study

Posted 25 Mar 2012 by Drugs.com

SUNDAY, March 25 – When it comes to what's best for their hearts, people walk a fine line between getting too much and too little sleep, a new study suggests. Adults who get fewer than six hours or more than eight hours of sleep a night are at greater risk for a variety of heart conditions, according to research led by Dr. Rohit Arora, chairman of cardiology at the Chicago Medical School. Sleeping too little puts people at significantly higher risk of stroke, heart attack and congestive heart failure, the researchers found. On the other hand, people who sleep too much have a higher prevalence of chest pain (angina) and coronary artery disease, a narrowing of the blood vessels that supply the heart with blood and oxygen. The findings are scheduled for presentation Sunday at the American College of Cardiology annual meeting in Chicago. The researchers analyzed data from more than 3,000 ... Read more

Low-Dose Daily Aspirin Enough to Help Heart Attack Patients: Study

Posted 25 Mar 2012 by Drugs.com

SATURDAY, March 24 – Heart attack patients who take either a high or low dose of aspirin daily have the same level of protection against another heart attack or other cardiovascular events such as stroke, according to a new study. Along with anti-clotting drugs, a daily aspirin is recommended for nearly all of the more than one million Americans who suffer a heart attack each year, but the most effective dose hasn't been determined. Higher doses of aspirin typically come with higher bleeding risks, so determining whether a high dose is needed or not has patient safety implications. To clarify the issue, researchers analyzed data from more than 11,000 heart attack patients around the world who were prescribed either a low daily dose (150 milligrams or less) or a high daily dose (more than 150 milligrams) of aspirin along with anti-clotting medications. The findings were to be presented ... Read more

Many Women Having a Heart Attack Don't Have Chest Pain

Posted 21 Feb 2012 by Drugs.com

TUESDAY, Feb. 21 – Two out of five women having a heart attack do not experience chest pain, according to a new study. Instead, they may have harder-to-recognize symptoms, such as pain in the jaw, neck, shoulders or back; stomach discomfort; or sudden trouble breathing, researchers said. That may be one reason why women also have a higher risk of dying from a heart attack when they're in the hospital compared to men, the study found. "The hallmark symptoms of a heart attack are chest pain and discomfort. But, women are more likely to have a different attack presentation," said study lead author Dr. John Canto, director of cardiovascular prevention, research and education at the Watson Clinic and director of the Chest Pain Center at Lakeland Regional Medical Center in Fla. Men and women who have risk factors for heart disease, such as obesity, diabetes, high blood pressure, high ... Read more

Stem Cell Treatment Might Reverse Heart Attack Damage

Posted 13 Feb 2012 by Drugs.com

MONDAY, Feb. 13 – Stem cell therapy's promise for healing damaged tissues may have gotten a bit closer to reality. In a small, early study, heart damage was reversed in heart-attack patients treated with their own cardiac stem cells, researchers report. The cells, called cardiosphere-derived stem cells, regrew damaged heart muscle and reversed scarring one year later, the authors say. Up until now, heart specialists' best tool to help minimize damage following a heart attack has been to surgically clear blocked arteries. "In our treatment, we dissolved scar and replaced it with living heart muscle. Such 'therapeutic regeneration' has long been the holy grail of cell therapy, but had never been accomplished before; we now seem to have done it," said study author Dr. Eduardo Marban, director of the Cedars-Sinai Heart Institute in Los Angeles. However, outside experts cautioned that the ... Read more
