What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores how the SomaSignal Test, a blood test, can aid in managing cardiovascular disease risk. The researchers aim to determine if knowing the test results leads to better treatment decisions for individuals at higher risk of heart problems. Participants will be divided into two groups: one will receive their test results, while the other will not be informed until the trial concludes. Patients managing cardiovascular risk factors like high cholesterol or high blood sugar at Intermountain Medical Center may find this trial suitable. As an unphased trial, it offers a unique opportunity to contribute to research that could enhance future cardiovascular care.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It seems that any changes to your medical management will be based on the results of the SomaSignal Test, but this is not explicitly stated.

What prior data suggests that the SomaSignal Test is safe for cardiovascular disease risk management?

Research has shown that SomaSignal Tests use protein patterns from a blood sample to predict health and disease risk. These tests have shown promise in helping doctors manage heart disease by providing crucial information about a patient's risk.

Regarding safety, the SomaSignal Test involves taking a small blood sample. Blood tests are generally safe and well-tolerated, with minor risks such as temporary discomfort or bruising at the needle site.

There are no specific reports of negative effects related to the SomaSignal Test itself. The test's primary goal is to collect data that aids doctors in making better decisions about managing heart disease. While the test does not involve any medication or treatment, it provides valuable information that can guide medical care. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the SomaSignal Test for cardiovascular disease risk management because it offers a new approach to understanding and managing heart health. Unlike traditional methods that rely on standard blood tests and patient history, the SomaSignal Test analyzes proteins in the blood to provide a more detailed picture of cardiovascular risk. This could allow for more personalized medical management, enabling doctors to tailor treatments more precisely to each patient's needs. By potentially identifying risk factors sooner and more accurately, this test could help prevent serious heart issues before they develop.

What evidence suggests that the SomaSignal Test is effective for cardiovascular disease risk management?

Research has shown that SomaSignal Tests use protein patterns from blood samples to predict heart health and future disease risks. This test provides a more accurate picture of heart disease risk by examining new risk markers. In this trial, participants in the "Informed" arm will receive their SomaSignal Test results, potentially leading to changes in their medical management based on these insights. Studies have found that SomaSignal Tests can help manage heart disease by identifying significant reductions in risk. For example, one study found that substantial weight loss could significantly lower heart disease risk. This test aims to provide a clearer understanding of heart health, which could lead to better medical care and outcomes. Participants in the "Uninformed" arm will not receive their test results until the study concludes, allowing for a comparison of outcomes between the two groups. ^{1 2 6 7 8}

Are You a Good Fit for This Trial?

This trial is for men and women aged 40-80 who are at a higher risk of heart problems, can give informed consent, agree to blood tests, and share their health records. They must be patients at Intermountain Medical Center and able to attend follow-up visits. Pregnant individuals or those with certain conditions like Systemic Lupus Erythematosus or recent participation in other trials cannot join.

What Are the Treatments Tested in This Trial?

Interventions

• SomaSignal Test Results

Trial Overview

The study is testing the impact of knowing one's SomaSignal Test results on managing heart disease risk. Initially, 12 people will get their results without randomization. Then, 200 more will be randomly assigned (2:1 ratio) to either learn about their test outcomes or not until after six months.

How Is the Trial Designed?

Group I: Informed Experimental Treatment 1 Intervention

Blood draw for SomaSignal Test and laboratory assessments at baseline, and 6 months (±30 days); SomaSignal Test results to be sent to investigators as available. Review and discussion of results with the participant from baseline and 6 months within 30 days (2-4 weeks to get SomaSignal results) after blood draw. Initiation of changes in medical management as soon as test results are known and discussed with patient. Patients will have a blood draw performed at baseline and 6 months for lipid panel, hemoglobin A1C, CBC, and BMP.

Group II: Uninformed Active Control 1 Intervention

Blood draw for SomaSignal Test at baseline and 6 months (+30 days). However, results will not be provided to clinician and participant until study conclusion. Patients contacted within 30 days (2-4 weeks) after baseline and 6-month visits to discuss treatment strategy (nothing, add/ remove medication, etc.) made at visit. Patients will have a blood draw performed at baseline and for lipid panel, hemoglobin A1C, CBC, and BMP SomaSignal Test results to be sent to investigators AFTER study conclusion. Patients will be provided with SomaSignal Test results after the 6 month post-test timepoint.

The Framingham Risk Score, while commonly used to assess 10-year risk for coronary heart disease (CHD), does not effectively identify many individuals who will develop CHD, highlighting the need for improved risk assessment tools.

Alternative methods such as coronary artery calcium scoring, C-reactive protein measurement, and evaluating heart rate recovery and exercise tolerance during stress tests may enhance risk stratification for patients at intermediate risk for CHD.

The CAROSS trial will involve 530 regular smokers aged 40-70 to determine if screening for carotid plaques can increase smoking cessation rates and improve control of cardiovascular risk factors over a 1-year period.

This study is unique as it will be the first to evaluate the effectiveness of carotid plaque screening in motivating smokers to quit and manage their cardiovascular health, providing insights into the potential benefits of awareness of subclinical cardiovascular disease.

The SCORE index significantly overestimated cardiovascular mortality, predicting rates three times higher than what was actually observed in the population aged 40 to 75 years in Castilla y León.

The study found low sensitivity and predictive values for the SCORE, especially in women and individuals under 65, indicating that the current risk assessment models need to be updated to improve their accuracy in predicting cardiovascular outcomes.

The Systemic COronary Risk Evaluation (SCORE) model, developed from data covering approximately 3 million person-years, effectively estimates the risk of fatal cardiovascular disease (CVD) events over a 10-year period, helping clinicians tailor preventative strategies based on total cardiovascular risk.

The SCORE model is being tested in the POWER study, which aims to include around 60,000 patients, to evaluate its effectiveness as a tool for reducing cardiovascular risk in clinical practice.

In a study of 720 adults in Poland, a high carotid-femoral pulse wave velocity (CFPWV) was strongly associated with an increased risk of cardiovascular disease (CVD), with an odds ratio of 2.29 for those with a SCORE risk of 5% or higher.

The study established that a CFPWV cut-off value of 11.7 m/s effectively differentiates between low and high CVD risk, demonstrating 58.6% sensitivity and 71.3% specificity, making it a useful measure for assessing cardiovascular health.

The Coronary Artery Calcium Score (CACS) is a valuable tool for improving cardiovascular risk assessment, as it can identify patients who may be at risk for atherosclerosis that traditional models like the Framingham Risk Score and SCORE might miss, potentially reducing unnecessary treatments.

A CACS of 0 can indicate a low risk, allowing for the avoidance of unnecessary interventions, while a CACS of 100 or higher suggests a need for statin treatment, highlighting the importance of CACS in guiding clinical decisions regarding cardiovascular health.
