According to Dr. George Lister, using high-dose epinephrine in children may impair organ function and survival after cardiac arrest. Limiting doses to recommended levels can reduce errors and improve outcomes.
A 40-minute surgical procedure called left cardiac sympathetic denervation (LCSD) reduces the risk of cardiac arrest and fainting episodes in people with long QT syndrome, a rare heart disorder. The study found that LCSD surgery reduced cardiac events by 91 percent compared to pre-surgery rates.
A study of 404 sudden cardiac arrest victims found that almost half did not receive CPR before EMS arrival. The most common reasons for no CPR included physical limitations, victim location, and signs of life.
A recent study by the American Heart Association found that hospital staff preparedness significantly impacts survival rates for cardiac arrests during night shifts. The research indicates that patients experiencing cardiac arrest at night have a lower survival rate compared to those who experience it during the day or evening shifts.
A trial of the clot-busting drug tenecteplase suggests it may improve outcomes in some cases of cardiac arrest. A pharmacist-managed service also showed promising results by reducing recidivism among CVD patients, with women achieving lower target cholesterol levels.
The study found that public access defibrillation increased from 0.82% to 2.05% between 1999 and 2002, with a 50% survival rate for those treated. Over 4,000 people were trained to use the devices, and 457 AEDs were registered.
A study by the University of Iowa and Michigan found that defibrillators in high-risk locations, such as hospitals and airports, are cost-effective. However, low-risk sites like schools and hotels are not economically viable options due to low usage rates.
Researchers found that cooling the brain to 33 degrees Celsius increased survival rates and reduced microscopic brain injury by half. Hypothermia treatment also stimulated brain recovery by increasing growth factors derived from glia-cells in the brain.
A new chest compression device has been shown to restore blood flow four times better than manual compressions, potentially saving more lives. Researchers tested the device on 20 pigs in cardiac arrest and found it restored vital organs with improved oxygenation.
A University of Pittsburgh study found a marker for blood clots in patients experiencing cardiac arrest outside the hospital. The researchers identified increased clotting in veins, which worsens with longer cardiac arrest duration.
Researchers from the University of Pittsburgh found that shocking the heart after prolonged cardiac arrest can cause further damage, highlighting the need for alternative treatment options. The study suggests that waiting a few minutes before defibrillation may be a more effective approach.
Researchers at Argonne National Laboratory are developing an ice slurry procedure to cool the blood and brain cells after cardiac arrests, with the goal of improving survival rates. The ice slurry cools the brain by 2-5 degrees Celsius quickly, giving medics more time to revive normal blood flow and brain activity.
A study of 122 men and women who suffered out-of-hospital cardiac arrests found that women were more likely to report psychological stressors as triggers before their arrest, while men were more likely to report physical exertion. The study suggests that emotional triggers may play a role in sudden cardiac death for women.
A new study found that amiodarone is the most effective anti-arrhythmic drug for treating out-of-hospital cardiac arrest, with almost twice as many patients surviving compared to lidocaine. The ALIVE trial provides clear guidelines for emergency responders and hospital staff on the best treatment option.
A study of 344 cardiac patients who experienced a near-death experience (NDE) after cardiac arrest found that younger patients were more likely to report NDEs, while deeper experiences were more common among women. Longitudinal follow-up revealed increased beliefs in an afterlife and reduced fear of death among those with NDEs.
UT Southwestern researchers say automated external defibrillators (AEDs) can be used by anyone with minimal training, and are becoming increasingly widespread. Studies have shown that early defibrillation can dramatically improve survival rates for cardiac arrest victims.
Researchers at UNC developed a technique to deliver oxygen-carrying fluid to resuscitate the heart after cardiac arrest. The method, selective aortic arch perfusion (SAAP), has shown promising results in animal studies and may help save trauma victims by allowing surgeons to repair damage.
Researchers found that chest blows from objects such as baseballs or swings can lead to commotio cordis, a type of sudden cardiac death. The study identified 124 cases, with most victims being male children under 12 years old, and emphasized the importance of public education and awareness in preventing these incidents.
A recent study published in the New England Journal of Medicine found that patients with cardiac arrhythmias have a similar accident rate to healthy drivers. The study, which analyzed data from over 600 patients, showed that only 11% of accidents were preceded by potential arrhythmia symptoms.
The Chicago HeartSave Program successfully reduced sudden cardiac deaths at O'Hare and Midway Airports by placing AEDs one minute apart, making them easy to spot. The devices helped minimize critical response times to emergency care and improved survival rates for victims of ventricular fibrillation.
Researchers at UT Southwestern Medical Center found that automated external defibrillators (AEDs) can save the lives of sudden cardiac arrest victims aboard aircraft, with a survival rate of 40% in a two-year study. The smaller, automated device requires less training to use safely and is approved for airline use.
A large multi-center study is testing the life-saving potential and cost effectiveness of public access defibrillation (PAD). PAD involves placing defibrillators in community locations, where trained volunteers can access them, to improve emergency treatment for sudden cardiac arrest victims.
The American Heart Association has revised its cardiopulmonary resuscitation (CPR) guidelines, eliminating the need for a pulse check by bystanders before starting chest compressions. The new guidelines instead recommend looking for signs of circulation such as breathing, movement, and response to stimulation.
Researchers found that extracts from Scutellaria baicalensis significantly reduce cellular damage due to free radicals. The extract helped cells regain their ability to contract rhythmically after simulating cardiac arrest, reducing cell death by 47% compared to untreated cells.
A University of Chicago study found that neighborhoods with more racially integrated populations have higher rates of bystander CPR during cardiac arrests. In contrast, predominantly white and black neighborhoods had lower CPR rates.
Researchers at the University of Washington have found that amiodarone can save lives in patients who do not respond to defibrillation, improving resuscitation rates by nearly 30% compared to standard treatments. The drug showed particular benefits for women and those treated late in the course of resuscitation.
Researchers discovered oscillations in individual heart cells causing beat-to-beat alternations, leading to fibrillation and death. A new test highlights this pattern for easier detection, potentially saving thousands of lives annually from sudden cardiac arrest.
A study suggests that adding 4 cents to ticket prices in professional sports venues could cover the cost of automated external defibrillators and training staff, potentially saving thousands of lives. The estimated annual attendance at major league football, basketball, baseball, and hockey games is over 120 million.
A clinical trial conducted at the University of Washington found that administering amiodarone to cardiac arrest victims improves resuscitation success rates by 26%, with a significant increase in hospital admissions among those not responding to shock treatment. The study suggests amiodarone as a potential game-changer for treating sh...
A study by the American Heart Association found that casinos and airplanes are more likely to have automated external defibrillators (AEDs) than primary-care physicians' offices. The devices were found on firetrucks, police cars, and in some airlines, but only six out of 51 offices had a defibrillator.
Research found that TV show CPR success rates are 2-5 times higher than real-life survival rates, with most TV patients being young and healthy. In contrast, actual patients often have chronic conditions or suffer permanent damage after CPR.
