EARLY-MYO-HF: Risk Stratification of Heart Failure in Cardiomyopathies.
Study Details
Study Description
Brief Summary
The investigators aimed to use CMR technique in helping diagnose the etiology of unknown cardiomyopathy. Try to make a risk stratification of susceptible heart failure based on the extent of myocardial impairment.

Detailed Description
Cardiomyopathy is a category of multiple causes of myocardial injury in structure and function, of which unexplained cardiomyopathy was most worried by cardiologists. Since the etiology confirmation sometimes still lacks of effective tools, therefore it can not be treated against etiology and may gradually developing to systolic or diastolic heart failure. The development of heart failure can be in different speeds, varying degrees, inconsistent in reversibility, and distinct response to treatment of heart failure.
In "real-world", ECG , cardiac ultrasound and myocardial enzymology can not be the whole to indicate the etiology of heart failure, so a strong clinical tool in the existing auxiliary examination is urgently needed and help to assess the risk of potential heart failure, therefore a reasonable treatment time window can be proposed.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: with CMR confirmed etiology Participants who were identified with cardiac magnetic resonance (CMR) in etiology were treated with drug including etiologic treatment,anti-myocardial remodeling. |
Drug: etiologic treatment,anti-myocardial remodeling
When the etiology was diagnosed clearly by cardiac magnetic resonance(CMR), participants were treated with drugs including etiologic treatment,anti-myocardial remodeling according to guidelines for treatment of cardiomyopathy.
Other Names:
|
Placebo Comparator: etiology unconfirmed without acute HF Participants who were not identified with cardiac magnetic resonance (CMR) in etiology and without acute hearts failure (HF) were treated with drug with anti-myocardial remodeling. |
Drug: anti-myocardial remodeling
When the etiology was not diagnosed clearly by cardiac magnetic resonance(CMR), in participant without companioned with acute heart failure, participants were treated with drugs including anti-myocardial remodeling according to guidelines for treatment of cardiomyopathy.
Other Names:
|
Placebo Comparator: etiology unconfirmed with acute HF Participants who were not identified with CMR in etiology but with acute hearts failure were treated with drug with anti-myocardial remodeling,anti-acute heart failure. |
Drug: anti-myocardial remodeling,anti-acute heart failure
When the etiology was not diagnosed clearly by cardiac magnetic resonance(CMR), in participant companioned with acute heart failure, participants were treated with drugs including anti-myocardial remodeling and anti- acute failure according to guidelines.
Other Names:
|
Experimental: etiology confirmed with acute HF Participants who were identified with CMR in etiology but with acute hearts failure were treated with drug with Etiological, anti-remodeling and symptom treatment. |
Drug: Etiological, anti-remodeling and symptom treatment
When the etiology was diagnosed clearly by cardiac magnetic resonance(CMR), in participants were companioned with acute heart failure, the participant should be treated with drugs including etiologic treatment,anti-myocardial remodeling and anti-acute heart failure according to guidelines for treatment of cardiomyopathy.
