Research/Clinical Trials

We're not just satisfied with today's answers. We're looking for tomorrow's answers, too.

The research team at the Columbia Hypertrophic Cardiomyopathy (HCM) Center focuses on revealing the underlying mechanisms that lead to the development of HCM and to discover novel biomarkers in the blood that can identify patients with HCM who are more likely to experience adverse cardiovascular events (e.g., arrhythmias, stroke, congestive heart failure, and sudden cardiac death). Additionally, we utilize large “real-world” databases to compare the effectiveness and safety of the available treatments for HCM. Our group is actively recruiting patients to participate in several trials. If interested, please contact us at 212-305-8013.
