What this trial studies

This study evaluates the impact of the nattokinase enzyme on inflammation and cardiovascular risk markers in individuals with dyslipidemia. It is a longitudinal double-blind randomized clinical trial involving hypertensive participants over a two-month period. The trial will compare the effects of nattokinase against a placebo, focusing on its potential to reduce oxidative stress and inflammation, which are critical factors in cardiovascular diseases. The study aims to fill a gap in existing research by assessing these effects specifically in dyslipidemic patients.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 with elevated LDL cholesterol and triglyceride levels, as well as those with reduced HDL cholesterol.

Not a fit: Patients with autoimmune diseases, diabetes, cancer, or those on anticoagulant medications may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a novel therapeutic approach to managing inflammation and cardiovascular risk in patients with dyslipidemia.

How similar studies have performed: While there is limited research specifically in dyslipidemic patients, previous studies have shown promising results for nattokinase in other contexts.
