Unexplained Arrhythmia Creates Risks
Emergency room patients who suffer an unexplained bout of atrial fibrillation, a common heart arrhythmia, appear to be at a very low risk of long-term complications.
Clot Busters Safe for Warfarin Patients
After a stroke, tPA (tissue plasminogen activator), also known as a clot buster, offers the most effective acute treatment.
FDA Delays Blood Thinner Eliquis Again
United States Food and Drug Administration officials today delayed approval of Eliquis ( apixaban ) to prevent stroke or systemic embolism in patients with a common heart arrhythmia for the second time.
Drug Drops AFib Stroke Risk
For most patients with a heart rhythm disorder called atrial fibrillation, a procedure that uses electrical currents can successfully restore a normal heart rhythm.
Too Much Exercise Harms Heart
Endurance exercises such as running and bicycling benefit overall health and improve longevity. However, there appears to be a point where too much of a good thing is possible.
Genetic Variant Tied to Dangerous Arrhythmia
Certain types of heart arrhythmias may be dangerous and are associated with an increased risk of sudden cardiac death. Now researchers have found a genetic variant that appears to be associated with an increased risk of both.
Asthma Meds Tied to Heart Arrhythmias
A type of inhaled asthma medication appears to slightly increase the risk that children or young adults will develop a potentially deadly heart arrhythmia.
Unnerving Sudden Cardiac Arrest
Patients with potentially fatal heart arrhythmias often benefit from receiving an implantable cardiac defibrillator ( ICD ) because of their high risk of sudden cardiac arrest.
Listen to Your Heart
Often a slow or racing heartbeat isn't a reason for concern. In some cases, however, it may suggest a heightened risk for a more serious heart condition.
Prolonging ICD Shocks Safe
A potentially fatal abnormal heartbeat means some patients need an implanted device to provide a shock when dangerous rhythms are detected. Cardiologists describe the shocking sensation "like being hit with a baseball bat in the chest."
