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.
**Because so much HCM information was presented at the Summit, this is the second of multiple blog entries. Stay tuned to HCMBeat for more highlights from the HCM Summit. To see Part I of this series of highlights from the HCM Summit VI, click here.**
The 6th International HCM Summit was held October 27, 28 and 29th in Boston, Massachusetts. This symposium brings together HCM professionals from around the world who are there to learn about and discuss the latest developments in the treatment of HCM.
The symposium was organized by long time HCM expert Dr. Barry Maron and his son, Dr. Martin Maron. Both Marons are now affiliated with Tufts Medical Center’s Hypertrophic Cardiomyopathy Center.
What follows are summaries from selected talks presented at the meeting. The presenter and their hospital affiliation are noted below, along with the topic of their presentation. When possible, you may access the presenters’ slides via hyperlink by clicking on the name. (Note that not all presenters made their slides available).

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.
