Summary:
This is an observational study in which data already collected from people treated with vericiguat are studied.

In observational studies, only observations are made without participants receiving any advice or any changes to healthcare.

Chronic heart failure with reduced ejection fraction (HFrEF) is a long-term condition that occurs when the heart is weak and cannot pump enough blood to the rest of the body with each heartbeat. This leads to a reduced supply of oxygen which the body requires to function properly. The common symptoms include breathlessness, weakness, fatigue, and swelling in the ankles and legs. If left untreated, heart failure can lead to other serious health problems, including damage to other organs, which may result in hospital stays and even death.

Vericiguat works by increasing the activity of an enzyme called soluble guanylate cyclase (sGC), which relaxes the blood vessels and allows more blood to flow through. As a result, the heart is able to pump better.

Vericiguat is available in Germany for the treatment of HFrEF based on the results of a study called VICTORIA. The VICTORIA study showed that vericiguat helps in lowering the chances of death or hospitalization due to heart failure. However, there is limited information available about the use of vericiguat for the treatment of HFrEF under real-world conditions in routine medical care.

The main purpose of this study is to collect information about how well vericiguat works in people with HFrEF who were newly treated with vericiguat. In addition, researchers will collect information about participants' basic characteristics, including their age, gender, other health conditions they might have, and the medicines they might be taking.

The data will come from 2 German health databases including people who newly started vericiguat treatment between September 2021 and September 2023.

Primary Outcome Measures: All-cause mortality rates after initiation of vericiguat, Number of patients who died between the "Vericiguat index date" and "cohort exit" according to their death date., Between September 2021 and September 2023|All-cause related hospitalization rates after initiation of vericiguat, Sum of all fully hospitalized cases of all patients between the "Vericiguat index date" and "cohort exit"., Between September 2021 and September 2023|Heart failure related hospitalization rates after initiation of vericiguat, Sum of all fully hospitalized cases with a main or secondary inpatient diagnosis according to ICD-10 GM Code I50.x or I11.0 between the "Vericiguat index date" and "cohort exit"., Between September 2021 and September 2023
Secondary Outcome Measures: Adherence of vericiguat drug use, Adherence will be assessed using the Medical Possession Ratio (MPR=days of supply/treatment duration)., Between September 2021 and September 2023|Titration pattern of vericiguat drug use, Titration patterns will be assessed by investigating indicators such as the starting dose, the maximum dose reached as well as the time until up-titration., Between September 2021 and September 2023|Patient persistence of vericiguat drug use, Persistence will be calculated via the time until discontinuation of vericiguat., Between September 2021 and September 2023|Socio-demographic characteristics of patients initiating vericiguat at baseline, Sex and age groups., Between September 2021 and September 2023|Clinical characteristics of patients initiating vericiguat at baseline, Pre-defined comorbidities, pre-defined comedications, all-cause hospitalization, worsening hart failure event, etc., Between September 2021 and September 2023|Medication of interest in the 3 months before and after initiation of vericiguat, Between September 2021 and September 2023
