简要总结
This study aims to evaluate the impact of omega-3 (O3) supplementation in participants with high blood pressure and elevated triglycerides, focusing on cardiovascular risk factors. The research is particularly relevant, as O3 has been previously validated for its effects on abnormal lipid levels. The primary and secondary objectives aim to explore the effects of O3, as well as its potential therapeutic benefits in preventing cardiovascular diseases.
The main goal of this research is to investigate how O3 supplementation influences several key cardiovascular risk markers and overall vascular health. Specifically, the study will assess and analyze changes in cholesterol levels, triglycerides, uric acid, and blood glucose levels. Since inflammation plays a major role in heart disease, the study will examine how O3 affects inflammatory markers, including ferritin, high-sensitivity C-reactive protein (hsPCR), and the neutrophil-to-leukocyte ratio. These indicators help determine the level of systemic inflammation in the body. The study also aims to measure whether O3 supplementation improves vascular elasticity.
Apart from the primary cardiovascular effects, the study also aims to determine the tolerance levels of participants receiving O3 supplementation based on their cardiovascular profiles.
The study is based on the hypothesis that taking 2 grams of O3 daily for 12 weeks will lead to a significant reduction in triglyceride levels, lower inflammation markers, improved metabolic risk factors, and enhanced arterial elasticity, which can prevent or slow the progression of cardiovascular diseases. This hypothesis is supported by growing scientific evidence that suggests O3 fatty acids, particularly long-chain polyunsaturated fatty acids (DHA and EPA), have strong cardioprotective properties.
This is a clinical study that is planned in a prospective, interventional, randomized, placebo-controlled, and double-blind format. This means that participants will be randomly assigned to either the treatment group or the placebo group, and neither the participants nor the researchers will know who is receiving the actual treatment until the study ends.
This study is a pilot study, meaning it is a small-scale preliminary study designed to test the hypothesis before conducting a larger trial.
A total of 100 participants will be recruited. Participants will be randomly assigned into two groups: O3 group, receives omega-3 (O3) treatment; and control group, receives a placebo. The assignment will be 1:1 randomization, meaning each participant has an equal (50%) chance of receiving either the treatment or the placebo. The number of participants was chosen based on estimates that a 10% reduction in blood pressure measurements (mean arterial, brachial systolic, brachial diastolic, or central systolic) would be a meaningful outcome.
The duration of omega-3 intervention is based on previous research.

结局指标
主要结局
Mean change in office systolic blood pressure from baseline
时间窗: From enrollment to the end of treatment at 12 weeks
Mean change in office Systolic blood pressure from baseline in Millimeter Mercury, it measures average changes in office systolic blood pressure. Blood pressure is assessed using standardized methods while the participant is seated and resting. The measurement is taken using a validated electronic BP monitor.
Mean change in office diastolic blood pressure from baseline
时间窗: From enrollment to the end of treatment at 12 weeks
Mean change in office Diastolic blood pressure from baseline in Millimeter Mercury, it measures average changes in office diastolic blood pressure. Blood pressure is assessed using standardized methods while the participant is seated and resting. The measurement is taken using a validated electronic BP monitor.
Mean change in 24h and Daytime Ambulatory Systolic Arterial Blood Pressure from baseline
时间窗: From enrollment to the end of treatment at 12 weeks
Mean change in 24h and Daytime Ambulatory Systolic blood pressure from baseline in Millimeter Mercury, it measures average changes in systolic blood pressure. Blood pressure is assessed using standardized methods for 24 hour ambulatory measurement using a validated BP device monitor.
Mean change in 24h and Daytime Ambulatory Diastolic Arterial Blood Pressure from baseline
时间窗: From enrollment to the end of treatment at 12 weeks
Mean change in 24h and Daytime Ambulatory Diastolic blood pressure from baseline in Millimeter Mercury, it measures average changes in diastolic blood pressure. Blood pressure is assessed using standardized methods for 24 hour ambulatory measurement using a validated BP device monitor.
Mean change in resting pulse wave velocity from baseline
时间窗: From enrollment to the end of treatment at 12 weeks
Measurement of pulse wave velocity (PWV) in meters per second. The calibrated and validated Mobil-O-Graph® portable monitor (IEM GmbH, Stolberg, Germany) will be used. This module is connected to a computer to record the brachial pulse wave. It performs pulse wave analysis based on the oscillometric method. The arterial pulsation generates pressure oscillations, which are transmitted to the blood pressure cuff and measured by the transducer to be interpreted by a specific software, recording the pulse wave of the brachial artery and deriving a pulse wave from the aortic arch. All measurements will be performed on the left arm of the participant, at rest. Subjects will be instructed to be with empty bladder, not to drink coffee 60 minutes before gauging and alcoholic beverage in the last 24 hours.
