Middle aged active have low risk of sudden cardiac arrest

Middle aged active have low risk of sudden cardiac arrest

Middle-aged athletes at low risk for sudden cardiac arrest while exercising — Physically active middle-aged adults have low risk of sudden cardiac arrest – Sudden cardiac arrest during sports activities is relatively low among physically active middle-aged adults, and older people can exercise without worrying about triggering a heart rhythm disturbance, revealed by American researchers.

Circadian rhythms linked to sudden cardiac attack

Study Links ‘Body Clock’ to Sudden Cardiac Death — ‘Biological clock’ may be behind sudden heart attacks – A new study uncovers the first molecular evidence linking the body’s natural circadian rhythms to sudden cardiac death (SCD). Ventricular arrhythmias, or abnormal heart rhythms, are the most common cause of sudden cardiac death: the primary cause of death from heart disease. They occur most frequently in the morning waking hours, followed by a smaller peak in the evening hours.

Financial reimbursement increases cardiac stress tests in patients

Cardiac stress imaging more frequent among patients whose physicians provide, bill for procedures – Financial reimbursement and ownership of cardiac imaging equipment appears to influence physicians’ use of cardiac stress testing. The study finds that doctors who are reimbursed for both performing the test using their equipment and then interpreting the results were 50 to 100 percent more likely to order cardiac imaging tests on their patients than those who don’t bill the fees.

Chest compression approach better after cardiac arrest

Using chest compressions first just as successful as immediate defibrillation after cardiac arrest — But in cases of long waits for EMS, University of Michigan Health System study shows chest compressions first approach may be better – Chest compressions before defibrillation in patients with sudden cardiac arrest is equally successful as immediate treatment with an electrical defibrillator, according to a new study by the University of Michigan Health System.

Cooling may benefit children after cardiac arrest

Cooling may benefit children after cardiac arrest — Multicenter study evaluates effectiveness of therapeutic hypothermia in extending survival and reducing brain injury. – When the heart is stopped and restarted, the patient’s life may be saved but their brain is often permanently damaged. Therapeutic hypothermia, a treatment in which the patient’s body temperature is lowered and maintained several degrees below normal for a period of time, has been shown to mitigate these harmful effects and improve survival in adults.

10 genes identified in connection with sudden cardiac death

You’re sitting at your desk and suddenly your heart is beating in overdrive or worse, lurching along like a car on fumes. It is a shocking, uncomfortable and frightening sensation. – Irregular heart rhythms are a common cause of sudden cardiac death or SCD, a condition that accounts for 450,000 deaths annually in the United States.

Cardiac imaging exams have radiation risks

People Without Symptoms of Heart Disease Should Exercise Caution in Obtaining Cardiac Imaging Exams, says Expert Panel led by Mayo Clinic Cardiologist – At the radiation dose levels used in cardiac imaging exams, such as cardiac CT or nuclear medicine scans, the risk of potentially harmful effects from ionizing radiation are low. However, since the exact level of risk is not known, people without symptoms of heart disease should think twice about seeking, or agreeing to, these types of cardiac studies.

Gasping and CPR help cardiac arrest victims survive

Gasping helps cardiac arrest victims survive. Gasping should not be mistaken for breathing and CPR should be initiated. – People who witness an individual collapse suddenly and unexpectedly should perform uninterrupted chest compressions even if the patient gasps or breathes in a funny way, research from the Resuscitation Research Group at The University of Arizona Sarver Heart Center shows.

Moderate alcohol consumption lowers cardiac risk in middle aged

In a study conducted by the Department of Family Medicine at the Medical University of South Carolina and published in the March 2008 issue of The American Journal of Medicine, researchers found that middle-aged non-drinkers who began consuming moderate amounts of alcohol saw an immediate benefit of lower cardiac disease morbidity with no change in mortality after four years. – Middle-aged non-drinkers who began consuming moderate amounts of alcohol saw an immediate benefit of lower cardiac disease morbidity with no change in mortality after four years, revealed by researchers.
