Differential Diagnosis and Risk Stratification in Patients With Suspected NSTEACS

Completed

• Conditions: Non ST Segment Elevation Acute Coronary Syndrome
• Interventions: Diagnostic Test: Approaches to differential diagnosis and risk stratification

• Registration Number: NCT04400500
• Lead Sponsor: National Research Center for Preventive Medicine

Brief Summary

To evaluate possibilities of rapid differential diagnosis and risk stratification in patients urgently admitted to the CCU with a suspected acute coronary syndrome without persistent ST-segment elevation (NSTEACS).

Detailed Description

Single centre prospective non-randomised non-comparative study of patients delivered by ambulance and admitted to the CCU with suspected NSTEACS.

Aims of this study are:

1. To characterize the contingent of patients admitted to the CCU with suspected NSTEACS.

2. To evaluate possibilities of fast differential diagnosis and risk stratification in patients admitted to the CCU with suspected NSTEACS using clinical data, ECG, biomarker levels (hsTn, NT-proBNP, hsCPR, cardiac FABP) as well as HEART, ADAPT, EDACS, T-MACS, GRACE, ACTION and TIMI scores.

3. To evaluate the correlation between clinical data, ECG, biomarker levels (hsTn, NT-proBNP, hsCPR, cardiac FABP) as well as HEART, ADAPT, EDACS, T-MACS, GRACE, ACTION and TIMI scores with presence and severity of coronary atherosclerosis in patients admitted to the CCU (intensive care unit) with suspected NSTEACS.
