Measuring Tryptase Levels in Patients with Stable Coronary Artery Disease

Investigation of the Role and Prognostic Value of Tryptase in Patients With Stable Coronary Artery Disease

Observational University of Thessaly · NCT06958016

This study is testing if measuring tryptase levels in people with stable coronary artery disease can help predict their risk of having serious heart problems in the future.

What this trial studies

This observational study aims to measure serum tryptase levels in patients with stable coronary artery disease (CAD) and correlate these levels with the severity of their condition. It will investigate the potential of tryptase as a prognostic biomarker for predicting future cardiovascular events, particularly the transition from chronic coronary syndrome (CCS) to acute coronary syndrome (ACS). The study focuses on the role of mast cell activation in plaque instability, which may contribute to sudden cardiovascular events in patients with CCS. By analyzing the relationship between tryptase levels and cardiovascular health, the study seeks to enhance understanding of CAD progression.

Who should consider this trial

Good fit: Ideal candidates are males and females aged 18 to 85 with clinical symptoms of angina and a positive SPECT scan for myocardial ischemia.

Not a fit: Patients with acute coronary syndrome, recent coronary interventions, or certain medical conditions such as autoimmune diseases or cancer may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new biomarker for predicting cardiovascular events in patients with chronic coronary syndrome.

How similar studies have performed: Previous studies have indicated a potential link between tryptase levels and coronary artery disease, suggesting that this approach may yield valuable insights.
