About this study

Official title: Investigation of the Metabolic Substrate of Patients With Myocardial Infarction and Derivation of a Risk Estimation Algorithm to Evaluate Cardiovascular Risk Beyond Standard Modifiable Risk Factors (SMuRFs) - (The MetaSMuRF Study)

Coronary heart disease (CHD) is the leading cause of mortality worldwide. Every year, millions of people suffer its most adverse manifestation, an acute myocardial infraction (AMI). The majority of these patients present at least one of the standard modifiable risk factors (SMuRFs). These include smoking, hypertension, dyslipidemia, and diabetes mellitus (DM). However, emerging scientific evidence recognizes a clinically significant proportion of patients presenting with life-threatening AMI without any SMuRF (SMuRF-less patients). This proportion of patients with ACS without SMuRF appears to be increasing during the last two decades and has recently been reported as high as 20% (of total AMIs). To date, there are no scientific data capable of highlighting specific risk factors-biomarkers responsible for the development of AMIs SMuRF-less patients. Concurrently, metabolomics is rapidly evolving as a novel technique of studying small molecule substrates, intermediates and products of cell metabolism. This technique could be utilized to flag patients with higher risk for increased atherosclerotic burden, and subsequent future adverse clinical events. Besides the already established biomarkers, several metabolomic indicators, such as ceramides (C16, C18 και C24), acylcarnitines, apolipoproteins (ApoΒ and ApoA1) and adiponectin, have been separately shown to increase the risk for coronary artery disease development and progression. Therefore, the two groups of patients (with SMuRFs vs SMuRF-less) will be compared regarding their metabolic fingerprints -specifically the aforementioned novel metabolomic biomarkers- and possible predictive factors leading to SMuRF-less AMI will be evaluated. On the basis of the above, the aim is to prospectively analyze a cohort of well-characterized patients with AMI. The rationale of the study is to investigate potential correlations between metabolic profile of patients and SMuRF-less AMI. This could lead to the development of predictive risk stratification algorithms for patients without SMuRFs and coronary artery disease.

The rationale of the study is to investigate potential correlations between metabolic profile of patients and SMuRF-less AMI. This could lead to the development of predictive risk stratification algorithms for patients without SMuRFs and coronary artery disease.

Blood tests (blood chemistry) will be received from each patient on admission and will be analyzed to assess patients' metabolic profile. In order to achieve full coverage of all compounds, different analytical platforms and methods, such as Enzyme-LInked Immunosorbent Assay (ELISA), Reversed Phase Liquid Chromatography tandem Mass Spectrometry (RPLC-MS/MS) and Hydrophilic Interaction Liquid Chromatography tandem Mass Spectrometry (HILIC-MS/MS) will be applied. Univariate and multivariate analysis with linear and logistic regression models will be used to investigate independent prognostic factors contributing to the occurrence of SMuRF-less AMIs. The potential application in daily clinical practice of a derived clinical predictive model-algorithm, possibly including a new panel of metabolomic biomarkers, will contribute to the early prognosis and personalized prevention of such a particular category of AMIs.

Questions about this trial

What is this clinical trial studying?

An observational study of Cardiovascular Diseases and Acute Myocardial Infarction, run by Aristotle University Of Thessaloniki.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 23 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Metabolomic biomarkers associated with SMuRF-less myocardial infraction (time frame: 3 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Aug 2024.
