One-hour Diagnostic Algorithm for NSTEMI

Russia20 participantsStarted 2017-05-02

Plain-language summary

Predictable values of the 1-hour algorithm for estimating the concentration of troponin using highly sensitive reagents are 98-100% for excluding myocardial infarction (MI) and 75-80% for identifying this pathology. Such algorithms are developed for the rapid confirmation or exclusion of myocardial infarction without ST-segment elevation and, when combined with clinical data and electrocardiogram, are used to assess the risk of adverse course of disease and to contribute to decision making about expediency of stay in the intensive therapy unit and early discharge. In mid-1980s, a new marker of myocardial damage was proposed, namely: fatty-acid-binding protein (FABP). However, the diagnostic value of FABP cannot be interpreted unambiguously because of insufficient number of studies determining the sensitivity and specificity of the test in various manifestations of acute coronary syndrome (ACS). Available literature presents a wide range of reference values of FABP for MI diagnosis. Reference value ranges are proposed by manufacturers of diagnostic kits based on previous studies. In addition, there is no information about the FABP changes during the first three hours of the disease, as well as there are no data on diagnostic value of changes in this indicator ("∆") in patients with ACS without ST-segment elevation. These considerations provide rationale and support novelty of the planned pilot study.

Exclusion Criteria: * Patients with ACS in the preceding 30 days * Cerebral blood circulation disorder * Recent surgical intervention * Extensive burns of degree 2-3 * Massive wounds and injuries * Percutaneous coronary intervention or cardioversion * Pregnancy or lactation * Malignant tumors of stage 4 * Severe renal insufficiency (GFR\< 30 mL/min)

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
