Every year, more than a thousand individuals in Costa Rica could be walking around with a ticking time bomb inside their chests. A landmark study conducted by researchers María Jesús Mora and Víctor Fernández from the University of Costa Rica (UCR) warns that up to 1,114 people annually face an elevated risk of sudden death due to a critical gap in our healthcare system: the lack of timely diagnosis for hereditary heart diseases.

“Familial cardiomyopathies usually have a genetic origin; they can be asymptomatic for years and, in some cases, manifest suddenly,” the UCR researchers noted. This silent nature makes early detection a literal matter of life and death.

When Sudden Death Isn’t a Heart Attack

One of the most concerning revelations brought forward by medical experts is the structural misunderstanding of how young people die abruptly. While the public often defaults to labeling sudden cardiac events as standard heart attacks (infarctions), the reality under the microscope is frequently different.

“Many sudden deaths in young people are not heart attacks, but rather hereditary conditions which, if detected in time, would allow families to be studied and prevent further deaths.” — Dr. Lawrence Chacón, Forensic Doctor & Cardiovascular Pathology Specialist

According to Dr. Chacón, while frontline clinical physicians are fully capable of identifying macro risk factors in individual patients, Costa Rica currently lacks a centralized, comprehensive medical pathway or dedicated facility where these patients can be automatically referred for structured, specialized genetic tracking.

Families Left in the Dark

The tragedy of sudden death leaves deep ripples across entire family trees. Beyond the immediate grief, surviving biological relatives are often left exposed to the exact same unmapped genetic vulnerabilities.

Dr. Vivien Araya, a prominent cardiologist and electrophysiologist, highlighted the post-tragedy vacuum currently plaguing families. “There is no unit where they can receive counseling to understand what happened or to know if other family members are at risk,” she warned.

The Proposed Solution: A Specialized Unit Within the CCSS

To combat this systemic vulnerability, the UCR study explicitly outlines the structural blueprint for creating a dedicated Familial Cardiomyopathy Unit directly within the Costa Rican Social Security Fund (CCSS).

This unit would function as a multi-disciplinary hub handling four key clinical goals:

• Early Diagnostic Protocols: Proactively testing high-risk patients using advanced cardiac mapping.
• Comprehensive Clinical Follow-Up: Providing lifelong monitoring for individuals diagnosed with genetic heart mutations.
• Family Risk Cascades: Systematically evaluating and tracking blood relatives of sudden death victims to intercept conditions early.
• National Registry Development: Building Costa Rica’s first unified epidemiological database to map these conditions over time.

Project researcher María Jesús Mora emphasizes the urgency: “Currently, many cases are identified too late, which reduces the possibilities of prevention for family members.”

Technically and Financially Viable

Crucially, the UCR project concluded that implementing this specialized framework is fully viable from technical, social, and economic perspectives. The formal proposal has already been delivered to the CCSS Board of Directors for analysis and potential deployment.

By filling existing gaps—such as weak coordination between specialized units, minimal diagnostic test availability, and the complete absence of a national registry—Costa Rica can pivot its public health system from reactive emergency care to aggressive, life-saving prevention. Prioritizing timely, genetic-level screenings won’t just optimize public hospital resources; it will give thousands of families years of healthy, uninterrupted lives.
