Spain Launches Major Study to Detect Hidden Heart Disease Risk

                <p>In one of the largest clinical experiments ever launched to combat atherosclerosis – the disease responsible for heart attacks and strokes – 8,000 healthy individuals in Spain will participate in a groundbreaking study. The ambitious project aims to identify cardiovascular risk factors *before* they become life-threatening, offering a new approach to preventative care. This research is particularly significant given that cardiovascular disease remains the leading cause of death globally.</p><p>Leading the initiative is the <strong>Centro Nacional de Investigaciones Cardiovasculares (CNIC) in Madrid</strong>, a world-renowned center for heart research. Cardiologists Borja Ibáñez and Valentín Fuster are seeking men and women between the ages of 18 and 69 who currently have no diagnosis of cardiovascular disease. The goal is to study seemingly healthy people, many of whom may be unaware of underlying issues within their arteries.</p><p><strong>Understanding Atherosclerosis</strong></p><p>Atherosclerosis is a silent threat. It often presents no noticeable symptoms, but over time, it causes a buildup of fat and cholesterol in the arteries, narrowing them and increasing the risk of sudden heart attack or stroke.  Alarmingly, previous CNIC studies analyzing over 4,000 Banco Santander employees revealed that six out of ten participants, despite feeling perfectly healthy, already showed early signs of the disease. This finding challenges the common belief that atherosclerosis primarily affects the elderly or those already diagnosed with heart conditions.</p><!-- adv-4c02620 --- 2025-12-27 20:30:57 -->

The new study, dubbed React, represents a leap forward in preventative medicine. Participants will receive comprehensive health assessments – typically costing thousands of euros – free of charge. These include three-dimensional ultrasounds of the carotid and femoral arteries, electrocardiograms, blood and urine analyses, retinal imaging, and, crucially, a sophisticated angio-CT scan to visualize the coronary arteries.

Advanced Technology for Early Detection

The angio-CT scan is a key component of the study’s innovative approach. This technology allows researchers to detect minuscule plaques, invisible with standard tests. Even small accumulations of plaque can signal a significantly elevated future risk. The study’s core strategy is to intervene early, even in the absence of symptoms. Individuals showing early signs of atherosclerosis will be enrolled in an intensive program encompassing dietary changes, increased physical activity, weight loss, and, if necessary, medications like statins – which are now widely available and affordable.

According to Dr. Ibáñez, this proactive strategy has the potential to alter the course of the disease. Previous studies have shown that plaques spontaneously disappear in only 8% of cases. With early and targeted intervention, researchers aim to increase that rate to 80%, not just slowing the progression of atherosclerosis, but reversing it.

Investment and Project Scope

The project is a substantial investment in cardiovascular health. The first phase of the study is funded with 23 million euros from the Novo Nordisk Foundation and involves 8,000 volunteers in Spain and an additional 8,000 in Denmark. The second phase, scheduled between 2027 and 2032, will cost approximately 40 million euros and will compare standard prevention methods with the intensive approach developed by the CNIC. Over 5,300 volunteers have already enrolled in Spain, but the research team is now focused on reaching populations often excluded from clinical trials: residents of rural areas, underserved communities, and individuals from vulnerable socioeconomic backgrounds. Atherosclerosis affects everyone, but access to preventative care is not equal.

The project also looks toward the future of public health. The concept is straightforward and revolutionary: cardiovascular screenings starting in young adulthood, rapid and portable ultrasounds for those exceeding certain risk thresholds, and short, early-stage therapies. Researchers believe that five years of treatment in a person’s 20s could be as beneficial as 35 years of treatment started too late. Meanwhile, global statistics are concerning. Since 1990, cases of cardiovascular disease have doubled, rising from 311 to 626 million, driven by sedentary lifestyles and unhealthy diets. “Simply treating illness is no longer enough,” warns cardiologist Ibáñez. “We are failing at prevention.” This underscores the need for policy changes, including higher taxes on ultra-processed foods and incentives for the consumption of fruits, vegetables, and olive oil. The cardiologists emphasize that saving millions of lives depends not only on laboratory breakthroughs but also on the daily choices of individuals.
