(1)Indication:Chronic Heart Failure.(2) Objectives: Primary objective is to evaluate the efficacy of the Hospital-Community-Family-Care Management Platform online compared with the regular clinic follow up in subjects with CHF (II-III class by NYHA).Secondary objectives is to assess the safety of the Management Platform online in subjects with CHF.(3) Study design: Prospective, randomized,controlled study with two follow up management groups: 1) the Hospital-Community-Family-Care Management Follow up Online;2) the regular monthly clinic follow up.Study population:Totally 1000 male and female subjects with CHF (II-III functional classes according to NYHA classification).(4) Quality assurance plan that addresses data validation and registry procedures, including any plans for site monitoring and auditing.(5) Data checks to compare data entered into the registry against predefined rules for range or consistency with other data fields in the registry.(6) Source data verification to assess the accuracy, completeness, or representativeness of registry data by comparing the data to external data sources.(7)Standard Operating Procedures to address registry operations and analysis activities, such as patient recruitment, data collection, data management, data analysis, reporting for adverse events, and change management.(8)Duration of follow up: The total follow-up time shall be 12 months.(9)Safety Assessment:Safety of the study will be evaluated by the following assessments: 1)Subject examinations (during the follow up period and extending up to 2 week after the end of the study) consisting of a subject interview (including direct questioning about adverse events), physical examination, assessment of body weight, Electrocardiogram (ECG) and echocardiogram (UCG), Left ventricular ejection fraction, assessed by echocardiography, The N-terminal prohormone of brain natriuretic peptide (NT-proBNP), a peptide hormone whose plasma concentration is inversely related to the severity of HF, NYHA functional status, assessed by subject interview, Quality of life (QoL), assessed by the Minnesota Living with Heart Failure questionnaire (MLHFQ), a validated questionnaire assessing QoL in subjects with heart failure. 2)Evaluation of clinically relevant safety laboratory parameters, such as complete blood count, serum creatinine, electrolytes, and liver enzymes.Any Adverse Events (AE) or Serious Adverse Events (SAE) and its potential causal relationship with the study will be recorded and evaluated.(10)
