Apical Aneurysms in HCM

Published on by hcmbeatLeave a comment

A recent paper published by doctors at Canada’s Peter Munk Cardiac Center looked at the implications of left ventricular apical aneurysms in hypertrophic cardiomyopathy,  This paper recommends that patients with an apical aneurysm of at least 2 centimeters consider prophylactic anticoagulant therapy to prevent stroke, as well as considering surgical placement of an implantable defibrillator to protect against sudden cardiac death.

A companion editorial suggests caution in basing aggressive measures on an aneurysm alone and says that all risk factors be considered together.

In 2017, HCMBeat covered a retrospective study of patients treated at Minneapolis Heart Institute and Tufts which discussed the risks for patients with apical aneurysms.  That can be found here.

An expert panel comprised of many of the world’s top HCM experts recently published a retrospective analysis in The American Journal of Cardiology which looked at septal myectomy over the last 60 years of practice.

 Beginning with the introduction of the procedure at the National Institute of Health in the early 1960s, this paper surveys the history of the procedure until the present day.  The conclusion of the paper is that myectomy remains the best treatment for patients with obstructive hypertrophic cardiomyopathy.

Recommendations for HCM Depart from 2020 ACC/AHA Guidelines

Published on by hcmbeat1 Comment

A recent article by several noted HCM experts shares their recommendations for the screening and evaluation of patients with HCM using several scenarios commonly encountered in clinical practice. Notably, this paper makes several recommendations which differ from the 2020 ACC/AHA Guidelines for the Diagnosis and Treatment of Patients with Hypertrophic Cardiomyopathy (2020 Guidelines).

In particular, the article recommends:

  • Cardiac MRI with contrast upon initial evaluation, and every 3 – 5 years thereafter.  (The 2020 Guidelines recommend Cardiac MRI in certain situations, but not for all patients)
  • Genetic testing only in cases where a pathogenic or likely pathogenic mutation has been identified in a family member and in limited other circumstances (the 2020 Guidelines recommends genetic testing for all as part of the initial assessment)
  • Screening of family members 12 or older only (the 2020 Guidelines recommend screening of children of any age when genetic HCM is diagnosed in a family member and no later than puberty, in any event)
  • That HCM patients be disqualified from competitive sports. (The 2020 guidelines instead recommend a shared decision making approach).

Sports and HCM – Moving Toward Shared Decision Making

Published on by hcmbeatLeave a comment

While competitive sports used to be frowned upon in the HCM literature, there is now some evidence that a patient’s risk from exercise is low when they have been implanted with an implantable cardioverter defibrillator (ICD). This feature from Medpage Today gives an overview of contemporary thinking about exercise in HCM patients.

Traditional Cardiovascular Risk Factors Worsen HCM

Published on by hcmbeatLeave a comment

According to this recent article in the European Heart Journal, traditional cardiovascular risk factors such as obesity, hypertension and diabetes are associated with more severe forms of HCM. Therefore, the authors suggest that these additional risk factors should be aggressively managed so as to limit their impact on HCM.
