One-year Prognostic Impact of Microcirculation Assessed by NH IMR Angio in Patients Hospitalized for Acute Myocarditis (MICROMYOC)
The goal of this observational study is to evaluate the association between post-coronary angiography IMR and medium-term clinical prognosis in patients with acute myocarditis. The main question it aims to answer is:
Is there a correlation between impaired microcirculation and the occurrence of serious clinical events in this population of patients?

Medidas de resultado primarias
Medida de resultado |
Medida Descripción |
Periodo de tiempo |
|---|---|---|
|
MACE
Periodo de tiempo: From the time of the coronary angiography up to one year
|
The primary endpoint is the 1-year incidence rate of MACE.
MACE is defined by a composite endpoint comprising: 1) all-cause mortality, 2) cardiac decompensation requiring readmission, 3) heart transplantation, 4) documented sustained ventricular arrhythmia lasting >30 seconds, and 5) recurrence of myocarditis.
|
From the time of the coronary angiography up to one year
|
Medidas de resultado secundarias
Medida de resultado |
Periodo de tiempo |
|---|---|
|
Individual components of the 12-month MACE: cardiovascular death, transplantation, hospitalization for heart failure, and persistent heart failure (reported separately)
Periodo de tiempo: From the time of the coronary angiography up to one year
|
From the time of the coronary angiography up to one year
|
|
Correlation between IMR angiographic NH (continuous variable) and: a) MRI imaging criteria (LVEF, fibrosis, septal involvement, edema); b) biological markers (maximum troponin, CRP)
Periodo de tiempo: From the time of the coronary angiography up to one year
|
From the time of the coronary angiography up to one year
|
|
Predictive value of MRI angiography: diagnostic performance in predicting the primary endpoint (ROC, optimal cut-off values, sensitivity/specificity)
Periodo de tiempo: From the time of the coronary angiography up to one year
|
From the time of the coronary angiography up to one year
|
|
Assessment of inter- and intra-observer reproducibility of the MR angiography NH calculation (if a subsample is reanalyzed)
Periodo de tiempo: From the time of the coronary angiography up to one year
