What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study will follow 2000 adults hospitalized with acute heart failure in Brazil to learn how they are treated and what happens to them over the next year. Researchers want to see if doctors are using the latest recommended medicines and find out what barriers prevent better care. The goal is to use this information to improve heart failure treatment and reduce deaths.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

This study will include adult patients (≥18 years) admitted to public and private hospitals in Brazil with acute heart failure-related presentations. Eligible participants comprise two main groups: (1) patients hospitalized for acute myocardial infarction (AMI) who develop newly identified left ventricular systolic dysfunction during hospitalization (LVEF ≤40), limited to up to 25% of the total study population; and (2) patients admitted with a primary diagnosis of decompensated heart failure, regardless of ejection fraction, defined according to the universal criteria for heart failure. In patients with heart failure with preserved ejection fraction (HFpEF), additional characterization will include H2FPEF and HFA-PEFF scores. Patients will be excluded if they decline participation during the informed consent process, have undergone surgical myocardial revascularization within the previous month, present with heart failure secondary to sepsis, or are admitted with cardiogenic shock.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria Adult patients (≥ 18 years) admitted to public and private hospitals with one of the two clinical conditions below: * Admission for AMI (Acute Myocardial Infarction) presenting with reduced ejection fraction during hospitalization (LVEF ≤ 40%) and which had not been previously identified (limit of 25% of the study sample included by this criterion) * Primary diagnosis of decompensated HF (regardless of ejection fraction), with the HF diagnosis established according to the universal definition of heart failure. In cases of HF with HFpEF, in addition to the data from the universal heart failure criteria, H2FPEF and HFA PEFF data will be collected. Exclusion Criteria * Refusal to participate in the study during the informed consent process; * Surgical myocardial revascularization in the last month; * Heart failure secondary to sepsis (sepsis as the origin of heart failure); * Cardiogenic shock.
