the goal of this observational study is to evaluate myocardial ischemia and myocardial microcirculation dysfunction in children with cardiovascular disease by myocardial stress perfusion imaging. During their disease progress, participants will undergo myocardial stress perfusion, laboratory tests when hospitalization and follow-up, and the baseline data will be collected in the admission. all the above examination data will be analysed to identify early subclinical myocardial changes and evaluate the value of magnetic resonance myocardial stress perfusion in predicting prognosis.
