Regional management of worsening heart failure: rationale and design of the CHAIN-HF registry.

AIMS: Heart failure (HF) is a progressive disease in which periods of clinical stability are interrupted by episodes of clinical deterioration known as worsening heart failure (WHF). Patients who develop WHF are at high risk of subsequent death, rehospitalization, and excessive healthcare costs. As such, WHF could be seen as a separate disease stage and precursor of advanced HF. Whether WHF has a substantial health, societal, and economic impact evidence regarding its multifactorial nature and the specific barriers in treatment, including advanced HF therapies, remains scarce. The CHAIN-HF registry aims to describe the incidence, characteristics, current treatment, and outcomes of WHF. Additionally, it will promote structured regional collaboration and educate on increasing awareness for WHF and describe the implementation of guideline directed medical therapy and utilization of advanced HF therapies in a collaborative network. METHODS AND RESULTS: The CHAIN-HF registry is a prospective, observational, and multicentre study from the collaborating hospitals (Rijnmond HF Network) in the Rotterdam area. Unselected and consecutive patients (irrespective of ejection fraction) with a WHF event will be included. Comprehensive data including demographics, co-morbidities, treatment, and in-hospital and post-discharge outcomes will be collected. Notably, data on socio-economic status, treatment decisions, and referral for advanced HF therapies will be included. CONCLUSIONS: CHAIN-HF will be the first prospective, dedicated WHF registry in a collaborative network of hospitals that will provide robust real-world evidence on the incidence, characteristics, and outcomes of WHF. Moreover, it will provide information on of the value of regional collaboration to improve awareness and outcomes of WHF.

Long-lasting symptoms and diagnostics in a patient with unrecognized right sided heart failure: Why listening to the heart is so important.

M Ebstein is usually diagnosed in early childhood or adolescence. The young woman in our case complainted of fatigue and shortness of breath, on physical examination she showed signs of heart failure with raised central venous pressure, palpable liver, an a cardiac murmer. Based on these findings she should have been referred to a cardiologist in an early stage after which transthoracic echocardiography resulted in the correct diagnosis. In this case the anomaly was missed for many years by different specialists and the patient was treated for liver disease, while she was suffering from liver congestion due to right-sided heart failure.
