About this study
Official title: PROgnostic Value of Precision Medicine in Patients With Myocardial Infarction and Non-obStructive Coronary artEries: the PROMISE Trial.
The aim of our study is to evaluate if the use of a precision-medicine approach with a specific therapy tailored on the underlying pathogenic mechanism will improve the quality-of-life in MINOCA patients. The investigators further aim at investigating wherever a precision-medicine approach will improve the prognosis, healthcare related costs, and if that a different profile of plasma biomarkers and microRNAs may serve as diagnostic tools for detecting specific causes of MINOCA and to assess response to therapy. Finally, beyond its pivotal role in differential diagnosis, the investigators hypothesize that cardiac magnetic resonance (CMR) may provide a morphological and functional cardiac characterization as well as help in the prognostic stratification.
Read the detailed description
PROMISE study is a randomized multicenter prospective superiority phase IV trial comparing "precision medicine approach" versus "standard of care" in improving the prognosis and/or the quality-of-life of patients presenting with MINOCA. Patients will be randomized 1:1 to "precision medicine approach" consisting of a comprehensive diagnostic work up aim at elucidating the pathophysiological mechanism of MINOCA and consequently a tailored pharmacological approach versus "standard of care" consisting of standard diagnostic algorithm and therapy for myocardial infarction.
The aim of the study is to evaluate if the use of a precision-medicine approach with a specific therapy tailored on the underlying pathogenic mechanism will improve the quality-of-life in MINOCA patients (primary objective). The investigators further aim at investigating wherever a precision-medicine approach will improve the prognosis, healthcare related costs, and if that a different profile of plasma biomarkers and microRNAs may serve as diagnostic tools for detecting specific causes of MINOCA and to assess response to therapy (secondary objectives). Finally, beyond its pivotal role in differential diagnosis, the investigators hypothesize that cardiac magnetic resonance (CMR) may provide a morphological and functional cardiac characterization as well as help in the prognostic stratification (secondary objective).
The study is a multicentre trial involving 3 centers: IRCCS Fondazione Policlinico Universitario A. Gemelli (Study Promoter), Centro Cardiologico Monzino IRCCS, IRCCS Policlinico San Donato.
It will include 180 patients aged >18 years hospitalized for MINOCA randomized 1:1 to a "precision medicine approach" consisting of a comprehensive diagnostic work-up, analysis of circulating biomarkers and micro RNA expression profile and pharmacological treatment specific for the underlying cause versus a "standard approach" consisting of routine diagnostic work-up and standard medical treatment.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Coronary angiographyProcedure or surgery
coronary angiography will be performed via the transradial or transfemoral approach with the use of a 6F sheath. Coronary angiography will be performed within 90 minutes from hospital admission in patients presenting with persistent ST-segment elevation, and within 48 hours in patients presenting with non-ST-segment elevation. Unfractionated heparin (initial weight-adjusted intravenous bolus of 60 IU/Kg, with repeat boluses to achieve an activated clotting time of 250 to 300 seconds) was administered in all patients. If evidence of plaque rupture
OCT imagingDiagnostic test
OCT imaging will be performed in the culprit artery in all patients randomized to the "precision medicine approach". A 0.014-inch guidewire will be placed distally in the target vessel and an intracoronary injection of 200 µg of nitroglycerine will be performed. Frequency domain OCT (FD-OCT) images are acquired by a commercially available system (C7 System, LightLab Imaging Inc/ St Jude Medical, Westford, MA) connected to an OCT catheter (C7 Dragonfly; LightLab Imaging Inc/ St Jude Medical, Westford, MA), which was advanced to the culprit lesion. The FD-OCT run will be performed using the integrated automated pullback device at 20 mm/s. During image acquisition, coronary blood flow will be replaced by continuous flushing of contrast media directly from the guiding catheter at a rate of 4 ml/s with a power injector in order to create a virtually blood-free environment.
Percutaneous coronary intervention (PCI):Procedure or surgery
PCI with stent implantation will be considered in selected cases with evidences of plaque rupture
Acetylcholine provocative testDiagnostic test
ACh will be administered in a stepwise manner into the left coronary artery (LCA) (20-200 μg) or into the right coronary artery (RCA) (20-50 μg) over a period of 3 min with a 2-3 min interval between injections. Coronary angiography will be performed 1 min after each injection of these agents and/or when chest pain and/or ischaemic ECG shifts were observed. The decision of testing with provocative test LCA or RCA as first will be left to the discretion of the physicians; both LCA and RCA will be tested if the first test was negative. Angiographic responses during the provocative test will be assessed in multiple orthogonal views in order to detect the most severe narrowing and/or analysed by using computerized quantitative coronary angiography (QCA-CMS, Version 6.0, Medis-Software, Leiden, The Netherlands).
TT-EchocardiographyDiagnostic test
TT-Echo will be used to calculate left and right ventricular and atrial dimensions, left and right ventricular systolic function, transmitral flow Doppler spectra, mitral and tricuspidal valve annulus tissue Doppler spectra, ejection time and stroke volume, inferior vena cava, aorta and pulmonary artery diameters and Doppler spectra, according to the recommendations of the American Society of Echocardiography.
TE/contrast echocardiographyDiagnostic test
In patients with angiographic evidence or suspicion of distal microembolization, TE-Echo consisting of an echocardiographic probe inserted in to the oesophagus will be used to detect a hidden cardioembolic source (i.e. left atrial thrombus); in patients with suspected left ventricular source of cardioembolism, contrast echocardiography consisting of a 0.3ml solution of SONOVUE will be used.
Cardiac magnetic resonanceDiagnostic test
CMR will be performed during hospital stay on a 1.5-T system equipped with a 32-channel cardiac coil. Patients underwent conventional CMR including cine, T2-weighted, first pass perfusion, and conventional breath-held late gadolinium enhancement (LGE).
Circulating biomarkersDiagnostic test
Blood sampling for circulating biomarkers and miRNA expression profile at the time or within 12 hours of coronary angiography. Blood sampling will be processed and analysed in the research laboratory of the Department of Cardiovascular Science. Biological aliquots will be preserved at XBiogem Biobank at Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome (see section 33).
Antiplatelet DrugDrug
acetylsalicylic acid (loading dose 250mg intravenously followed by 75mg orally) + P2Y12 receptor inhibitor (i.e. Clopidogrel, 300 or 600mg loading dose orally, followed by 75 mg orally daily).
StatinDrug
i.e. atorvastatin; dosages titrated on the patient's clinical characteristics
Beta blockerDrug
i.e. bisoprolol; dosages titrated on blood pressure, ECG, heart rate
ACEi/ARBDrug
i.e. ramipril; dosages titrated on blood pressure, ECG, heart rate

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The aim of our study is to evaluate if the use of a precision-medicine approach with a specific therapy tailored on the underlying pathogenic mechanism will improve the quality-of-life in MINOCA patients. The investigators further aim at investigating wherever a precision-medicine approach will improve the prognosis, healthcare related costs, and if that a different profile of plasma biomarkers and microRNAs may serve as diagnostic tools for detecting specific causes of MINOCA and to assess response to therapy. Finally, beyond its pivotal role in differential diagnosis, the investigators hypothesize that cardiac magnetic resonance (CMR) may provide a morphological and functional cardiac characterization as well as help in the prognostic stratification.

Patients will be randomized 1:1 to "precision medicine approach" consisting of a comprehensive diagnostic work up aim at elucidating the pathophysiological mechanism of MINOCA and consequently a tailored pharmacological approach versus "standard of care" consisting of standard diagnostic algorithm and therapy for myocardial infarction.
The aim of the study is to evaluate if the use of a precision-medicine approach with a specific therapy tailored on the underlying pathogenic mechanism will improve the quality-of-life in MINOCA patients (primary objective). The investigators further aim at investigating wherever a precision-medicine approach will improve the prognosis, healthcare related costs, and if that a different profile of plasma biomarkers and microRNAs may serve as diagnostic tools for detecting specific causes of MINOCA and to assess response to therapy (secondary objectives). Finally, beyond its pivotal role in differential diagnosis, the investigators hypothesize that cardiac magnetic resonance (CMR) may provide a morphological and functional cardiac characterization as well as help in the prognostic stratification (secondary objective).
The study is a multicentre trial involving 3 centers: IRCCS Fondazione Policlinico Universitario A. Gemelli (Study Promoter), Centro Cardiologico Monzino IRCCS, IRCCS Policlinico San Donato.
It will include 180 patients aged >18 years hospitalized for MINOCA randomized 1:1 to a "precision medicine approach" consisting of a comprehensive diagnostic work-up, analysis of circulating biomarkers and micro RNA expression profile and pharmacological treatment specific for the underlying cause versus a "standard approach" consisting of routine diagnostic work-up and standard medical treatment.

Interventions
| Intervention | Type | Arms |
|---|---|---|
| Coronary angiographycoronary angiography will be performed via the transradial or transfemoral approach with the use of a 6F sheath. Coronary angiography will be performed within 90 minutes from hospital admission in patients presenting with persistent ST-segment elevation, and within 48 hours in patients presenting with non-ST-segment elevation. Unfractionated heparin (initial weight-adjusted intravenous bolus of 60 IU/Kg, with repeat boluses to achieve an activated clotting time of 250 to 300 seconds) was administered in all patients. If evidence of plaque rupture | Procedure or surgery | "Precision medicine approach", "Standard approach" |
| OCT imagingOCT imaging will be performed in the culprit artery in all patients randomized to the "precision medicine approach". A 0.014-inch guidewire will be placed distally in the target vessel and an intracoronary injection of 200 µg of nitroglycerine will be performed. Frequency domain OCT (FD-OCT) images are acquired by a commercially available system (C7 System, LightLab Imaging Inc/ St Jude Medical, Westford, MA) connected to an OCT catheter (C7 Dragonfly; LightLab Imaging Inc/ St Jude Medical, Westford, MA), which was advanced to the culprit lesion. The FD-OCT run will be performed using the integrated automated pullback device at 20 mm/s. During image acquisition, coronary blood flow will be replaced by continuous flushing of contrast media directly from the guiding catheter at a rate of 4 ml/s with a power injector in order to create a virtually blood-free environment. | Diagnostic test | "Precision medicine approach" |
| Percutaneous coronary intervention (PCI):PCI with stent implantation will be considered in selected cases with evidences of plaque rupture | Procedure or surgery | "Precision medicine approach" |
| Acetylcholine provocative testACh will be administered in a stepwise manner into the left coronary artery (LCA) (20-200 μg) or into the right coronary artery (RCA) (20-50 μg) over a period of 3 min with a 2-3 min interval between injections. Coronary angiography will be performed 1 min after each injection of these agents and/or when chest pain and/or ischaemic ECG shifts were observed. The decision of testing with provocative test LCA or RCA as first will be left to the discretion of the physicians; both LCA and RCA will be tested if the first test was negative. Angiographic responses during the provocative test will be assessed in multiple orthogonal views in order to detect the most severe narrowing and/or analysed by using computerized quantitative coronary angiography (QCA-CMS, Version 6.0, Medis-Software, Leiden, The Netherlands). | Diagnostic test | "Precision medicine approach" |
