A recent study published in the American Journal of Cardiology found that the standards propounded by the American College of Cardiology Foundation with the American Heart Association (ACC/AHA) were superior in predicting which patients would benefit from an implantable cardiac defibrillator (ICD) compared to the calculator set forth by the European Society of Cardiology (ESC). According to the study, the use of the ESC tool will result in more high-risk patients going unprotected against sudden death.
Specifically, the study found that out of a group of 288 HCM patients, 14 who experienced aborted sudden cardiac arrest (or 43%) would not have qualified for an ICD under the ESC risk model compared to 7% of patients under the ACC/AHA guidelines.
The ACC/AHA guidelines are:
A companion editorial by Dr. Andreas S. Barth pointed out the shortcomings of both models, and reaffirmed the necessity for shared decision making between physicians and patients. Dr. Barth also expressed hope that a more accurate predictive model will evolve, though he acknowledged the impossibility of designing a model which could predict future events with certainty.
According to research presented this week at the American Heart Association’s Scientific Sessions, the risk of dying from sudden cardiac arrest during or within 1 hour of sex is less than 1%.
The study, published by Dr. Sumeet Chugh of Cedars-Sinai Hospital in Los Angeles, looked at data collected in the Oregon Sudden Unexpected Death Study (Oregon SUDS) database between 2002 and 2015.
Dr. Chugh emphasized that survival was higher in the group of patients who received CPR, re-emphasizing the importance of teaching CPR in the general population.

The HCM Risk–SCD Score
In 2014, the European Society of Cardiology (ESC) introduced a numerical predictor (the “HCM Risk–SCD score”) to assist physicians in identifying those patients at highest risk for sudden cardiac death who would benefit from the implantation of a prophylactic implantable cardioverter-defibrillator.
Using an algorithm generated by the answers to a series of questions, the tool estimates the 5-year risk of sudden cardiac arrest for any particular patient. You can find the tool online here.

It’s strange to think that a chaotic arrhythmia in the heart might actually appear to be a seizure caused by something that has gone haywire in the brain, but with sudden cardiac arrest (SCA) this can sometimes happen.
This is the true story of what happened to my daughter.

Pippa Middleton, who came to the public’s attention during the wedding of her sister Katherine to Prince William, has recently dedicated her efforts toward raising money for HCM genetic testing and research. Middleton’s efforts are in honor of her late friend Miles Frost, who was lost to sudden cardiac arrest due to HCM in 2015. Frost’s father, British journalist and media personality David Frost, died from HCM just two years earlier in 2013, but this information was never communicated to the family.
The Miles Frost Fund, a partnership with the British Heart Foundation , helps families who have lost a member to a sudden death obtain genetic testing in order to learn if other family members are similarly affected. The Frost Fund also funds research by U.K.researchers working towards finding a cure for HCM.
The work of Parent Heart Watch – an organization formed by parents of children who died due to sudden cardiac arrest -was featured on the Today show this week.
Parent Heart Watch works tirelessly so that AEDs are available in schools and on playing fields around the U.S. to ensure that children will not fall victim to SCA.
Great work PHW!
This article, published in this week’s Women’s Health magazine, features the former ballerina and beauty queen turned vocal patient activist. These days, Lindsay has focused her efforts on saving lives from sudden cardiac arrest. Lindsay’s efforts in the state of Ohio have resulted in proposed legislation to identify student athletes at risk of sudden cardiac arrest, while her partnership with the American Heart Association is steadily making CPR and AED training a graduation requirement in high schools across the nation.
Watch for more life-saving advocacy from Lindsay in the future. She is clearly much more than another pretty face!
Updated to include a video of Lindsay discussing her implantation with a S-ICD device.
According to research presented at the 2016 European Society of Cardiology Congress today, sudden cardiac arrest from HCM, which has long been thought to result from exercise, is actually more likely to occur at rest, or even during sleep, according to Dr. Gherardo Finocchiaro, a cardiologist at St George’s University in London. Dr. Finocchiaro also pointed out that of the 184 HCM patients in his study, almost 80% had no previous symptoms of HCM, and only 1 in 5 had been diagnosed with HCM before their deaths. Interestingly, most of the sudden deaths from HCM analyzed in the study occurred in patients in their 30s and 40s.
Doctors at the University of Pennsylvania have created a new model which they say can predict the risk of sudden cardiac arrest in people without known heart disease. According to the article, published recently in Circulation, low levels of albumin, a protein commonly tested in routine blood panels, is a novel risk factor among the twelve factors identified. This article in Cardiac Rhythm News offers more details.
