Restyle HCM Study: Ranolazine Doesn’t Improve HOCM Heart Failure Symptoms

Dr. Iacopo Olivotto and a team of Italian researchers conducted a recent multi-center trial of the late sodium channel blocker ranolazine.  The results of the trial showed that the drug failed to improve functional capacity, diastolic function, quality of life or brain natriuretic peptide (BNP) levels in 80 non-obstructive HCM patients.

Nevertheless, the researchers found that ranolazine is a very safe drug which may still be useful in the treatment of HCM by reducing arrhythmias and improving angina.

A companion editorial by Dr. Perry Elliot from the U.K. shed light on the difficulties inherent in designing clinical trials for HCM.  Dr. Elliot noted that Restyle HCM was the third unsuccessful attempt at finding a new drug for HCM in the past year since a study on  eleclazine, a drug with similar properties, and another for the drug perhexilene were both halted last year due to lack of efficacy.

Regardless, Dr. Elliot stated that increasing worldwide collaboration between HCM centers and expanding knowledge of certain sub-types of HCM treatable with specifically targeted therapies substantially improve the outlook for upcoming HCM drug trials.

One Size Does NOT Fit All: Treatments Differ by Stage in HCM

There are distinct stages of HCM and treatments will vary according to the stage. Therefore, it is important, according to a recent article in the Netherlands Heart Journal, for patients to seek treatment from teams experienced in the the treatment of HCM.  These professionals are able to recognize transitions in the course of the disease as they occur, and then implement necessary changes in treatment.

In this thorough overview of HCM and its treatment, Dr. Iacopo Olivotto and his colleagues in the Netherlands observe that HCM is seen infrequently by community cardiologists (as compared to more common heart conditions like coronary artery disease). Hence, one of the major difficulties in HCM practice has been identification of patients at highest risk.
