The main goal of this observational study is to learn about the epidemiological characteristics of heart failure among elder population in Beicai community in Shanghai and construct a community-based database and biobank. The main question it aims to answer is:
What is the prevalence and prognosis of different stages of heart failure among elder population in community in Shanghai? And what are the influencing factors? What are the best screening strategies and hierarchical management strategies among different stages of heart failure patients in community? Participants are the elderly people aged 60 years or older in Beicai community in China. The follow-up will be programmed every 2 years.
Heart failure is a serious manifestation or advanced stage of various heart diseases with high mortality and re-hospitalization rates, and early diagnosis of heart failure is important to improve patient survival. Currently, the prevalence of preclinical heart failure (heart failure stage B) is lacking in China, and the rate of progression of heart failure from stage A/B to symptomatic heart failure (heart failure stage C) and end-stage heart failure (heart failure stage D) and the factors influencing the heart failure development are unknown.
The study is an ongoing prospective community-based study. After enrollment, a questionnaire, physical examination, laboratory examination and imaging examination will be administered to each participant at baseline and every 2 years in the follow-up. The laboratory and imaging examination include: blood/urine sample and biochemical measurements, electrocardiogram, echocardiograph, etc. In the follow-up, the incidence of cardiovascular disease, heart failure, other CV events and mortality will be recorded. Whether at baseline or follow-up, if the investigators find that patients are unclear about their disease status, the investigators will notify them by phone and record their subsequent medical behavior and results.
In this study, a community-based database and biobank will be established for early screening and long-term prognosis of heart failure in elderly population. Through the analysis of the data, the epidemiological characteristics of early stage of heart failure in elderly population in Shanghai can be identified and a multivariable model predicting heart failure in early stage will be constructed. Furtherly，the investigators will explore the referral criteria and hierarchical management strategies for heart failure through the cooperation between community hospitals and comprehensive hospitals.

| Prevalence of early heart failure | The prevalence of early heart failure was defined as morbidity of stage A heart failure and stage B heart failure. Stage A HF was defined as at risk for HF but without current or previous symptoms/signs of HF and without structural/functional heart disease or abnormal biomarkers.(eg. patients with hypertension, coronary artery disease, diabetes, obesity, atrial fibrillation/atrial flutter or tumour). Stage B HF was defined as no symptoms or signs of HF and evidence of one of the following:1) EF value<52 in male and <54 in female. 2) Increased NT-proBNP levels (≥125 pg/ml) or elevated TnT levels (>0.017ng/ml). |

| Progress of heart failure of Stage A | The morbidity rate of stage B heart failure, stage C heart failure and stage D heart failure in stage A heart failure patients in 2 year, 6 years and 10 years. Stage A HF was defined as at risk for HF but without current or previous symptoms/signs of HF and without structural/functional heart disease or abnormal biomarkers.(eg. patients with hypertension, coronary artery disease, diabetes, obesity, atrial fibrillation/atrial flutter or tumour). Stage B HF was defined as no symptoms or signs of HF and evidence of one of the following:1)EF value<52 in male and <54 in female.2) Increased NT-proBNP levels (≥125 pg/ml) or elevated TnT levels (>0.017ng/ml). Stage C/D HF was defined as previous history of HF or structural heart disease with current or previous symptoms of HF (eg. dyspnea, swelling of both lower extremities), diagnosed by two cardiac specialists. | Following up 10 years |
