DCM - Dilated Cardiomyopathy Clinical Trial
Official title:
Observational Study for Patients With Dilated Cardiomyopathy
Observational study on patients with dilated cardiomyopathy aims to investigate the correlation between cardiac fibrosis, as indicated by cardiac magnetic resonance, and the prognosis of patients with dilated cardiomyopathy, and further to explore biomarkers for cardiac fibrosis and adverse prognosis of dilated cardiomyopathy. Therefore, endpoints indluding all-cause mortality, cardiovascular death, ventricular arrythmia, non-fatal stroke, non-fatal myocardial infarction, sudden death, successful cardiopulmonary resuscitation will be evaluated.

---|---|---|---|---|
Primary | All-cause death | All-cause mortality refers to death from any causes. | 5 YEARS. | |
Secondary | Cardiovascular death | Cardiovascular death include death caused by stroke, MI, HF, sudden death or any other death attributed to cardiovascular diseases. | 5 YEARS. | |
Secondary | Ventricular tachycardia and fibrillation and flutter | Ventricular tachycardia is an abnormally fast heart beat (with three or more consecutive heart beats at least 100 beats per minute) that originates from one of the ventricles in the heart (ICD-code I47.2), respectively.Ventricular fibrillation (VF) is a very rapid (150-500 bpm) irregularly irregular disorganized ventricular rhythm of varying configuration; with time, the amplitude of the fibrillation wave becomes progressively smaller, particularly immediately before death. Ventricular flutter (VFL) is a very rapid (180-250 bpm) and regular ectopic ventricular rhythm with undulations of equal amplitude and usually rapidly degenerates to VF(ICD-code I49.0). | 5 YEARS. | |
Secondary | nonfatal stroke | Stroke (ICD-Code I60, I61, I63, I64) is a focal neurological deficit with symptoms continuing for more than 24 hours or leading to death with no apparent cause other than vascular. Stroke as an endpoint in this study includes definite ischemic stroke, primary intracerebral hemorrhage and subarachnoid hemorrhage with evidence from CT or MRI scan within 14 days of onset or autopsy confirmation, and stroke of unknown type etiology when CT, MRI, or autopsy are not done and information is inadequate to diagnose the etiology definitely. | 5 YEARS. | |
Secondary | nonfatal myocardial infarction | Acute myocardial infarction (MI) (ICD-Code I21) is defined when any one of the following criteria occurs. (1) Detection of a rise and/or fall of cardiac biomarker values, with at least one value above the 99th percentile upper reference limit and with at least one of the following manifestations: symptoms of ischaemia that should have lasted for at least 30 minutes and should not have been responsive to sublingual administration of nitrates; new or presumed new significant ST-segment-T wave changes or new left bundle branch block (LBBB); development of pathological Q waves in the ECG; imaging evidence of new loss of viable myocardium or new regional wall motion abnormality. (2) Identification of an intracoronary thrombus by angiography or autopsy. (3) Cardiac death with symptoms suggestive of myocardial ischaemia and presumed new ischaemic ECG changes or new LBBB, but death occurred before cardiac biomarkers were obtained, or before cardiac biomarker values would be increased. | 5 YEARS. | |
Secondary | sudden death | Sudden death (ICD-Code I46.1, R96) encompasses any death of unknown origin occurring instantly or within an estimated 24 hours after the onset of acute symptoms as well as unattended death for which no likely cause can be established by autopsy or recent medical history. | 5 YEARS. | |
Secondary | Cardiac arrest with successful resuscitation | ICD-Code I46.0 | 5 YEARS. | |
Secondary | Hospitalization for heart failure | Congestive heart failure (HF) (ICD-Code I50) requires the presence of three conditions, namely symptoms, such as dyspnea, clinical signs, such as ankle edema or crepitations, and the necessity to initiate treatment with open-label diuretics, vasodilators or antihypertensive drugs. HF cases may also be adjudicated as chronic stable HF but this is not considered an outcome of the present study. | 5 YEARS | |
Secondary | Heart transplatation | Heart replaced by heterogenous or homogenoustransplant due to end-stage heart failure. (ICD-Code Z94.1). | 5 YEARS |
