by John Mandrola, MD Last night my Twitter stream lit up with the news that NHL player Rich Peverley collapsed from a heart arrhythmia. Fortunately, he was successfully treated, and is reported to be in good condition. Here is a link to the best story I could find. It sounds awfully significant. [Dr.] Salazar said of the treatment, “We provided oxygen for him. We started an IV. We did chest compressions on him and defibrillated him, provided some electricity to bring a rhythm back to his...

A cardiac monitor about the size of a USB flash drive that’s implanted under the skin was six to seven times more likely to detect atrial fibrillation, an abnormal heart rhythm that’s a risk factor for stroke, according to a science report presented at the American Stroke Association’s International Stroke Conference 2014.   The monitor could help identify the 30 percent of ischemic strokes with no apparent cause.  Ischemic strokes are caused by a clot in a blood vessel in or near the brain.   “Atrial fibrillation can...

On Aug. 22, 2013, Sue Hostler arrives at the Philadelphia International Airport to catch a flight home. A frequent business traveler, she knows her way around the airport and runs to get on an elevator in a remote area of Terminal F, which is used for commuter flights. A young man reaches and enters the elevator just before her, and the doors close before she can join him. When Hostler hits the “up” button a few seconds later, the doors reopen and...

Three young adults died suddenly in the past year of severe heart inflammation induced by Lyme disease, a cardiac manifestation that has surprised some medical investigators. One of those deaths occurred in New York,  say federal scientists at the Centers for Disease Control and Prevention, who emphasized that sudden cardiac death is possible in young people infected by Lyme bacteria. Before these three Lyme-related sudden deaths, only four cases had been reported in medical history. Lyme disease was first discovered and described...

Nanci Hellmich, USA TODAY Many sudden cardiac arrests leave a calling card in advance. More than half of middle-aged men who experienced sudden cardiac arrests had symptoms up to a month beforehand, a new study shows. Most of the symptoms — including chest pain, shortness of breath, dizziness, faintness or heart palpitations — occurred four weeks to one hour before their hearts suddenly stopped, according to the research presented at the American Heart Association's Scientific Sessions in Dallas.

Sten Rubertsson, M.D., Ph.D., of Uppsala University, Sweden and colleagues assessed whether cardiopulmonary resuscitation (CPR) in which chest compressions are delivered with a mechanical device would result in superior 4-hour survival in patients with out-of-hospital cardiac arrest compared to CPR with manual chest compression. This multicenter clinical trial, which included 2,589 patients with out-of-hospital cardiac arrest, was conducted between January 2008 and February 2013 in 4 Swedish, 1 British, and 1 Dutch ambulance services and their referring hospitals. Four-hour survival was achieved...

Sweden has found a faster way to treat people experiencing cardiac emergencies through a text message and a few thousand volunteers. A program called SMSlivräddare, (or SMSLifesaver) (link in Swedish) solicits people who’ve been trained in cardiopulmonary resuscitation (CPR). When a Stockholm resident dials 112 for emergency services, a text message is sent to all volunteers within 500 meters of the person in need. The volunteer then arrives at the location within the crucial first minutes to perform lifesaving CPR. The odds for surviving cardiac arrest...

A high resting heart rate proved to be a strong and independent predictor of cognitive decline within the next 4 years in a study of nearly 28,000 patients at high cardiovascular risk. The clinical implications of this finding, however, remain unclear, according to Dr. Darryl P. Leong. "What this study cannot answer, and which must be answered, is whether resting heart rate is just a marker of the risk of cognitive decline or whether it exists in the causal pathway. Further research...

Sudden cardiac arrest -- when your heart stops functioning because of an electrical disturbance, which can lead to death if not treated immediately with CPR or defibrillation -- is known to occur more often between the hours of 6 a.m. and 10 a.m. But why? According to new research, it could have something to do with levels of a protein called KLF15, which regulates electrical activity in the heart. Dr. Mukesh Jain, M.D., of Case Western Reserve University, and colleagues found that people...
