About this study

Official title: COPD in Patients Hospitalized for Acute Decompensated Heart Failure.

The presence of chronic obstructive pulmonary disease (COPD) would confer increased in-hospital mortality and length of hospital stay in patients with acute decompensated heart failure Assess the (1) prevalence of COPD in patients who are hospitalized for acute decompensated heart failure and (2) the association between COPD and in-hospital mortality or length of stay in this cohort.

Read the detailed description

Background:

The prevalence of mild to moderate COPD is ~5%-10% with one-year mortality around 3% while heart failure affects is1%-3% with one year mortality 5-7% in the community. The mortality of COPD and heart failure dramatically increase following hospitalization.

Heart failure and COPD are independent predictors of increased morbidity and mortality. COPD and heart failure frequently co-exist in an individual patient through the shared risk factors. The prevalence of COPD in heart failure patient-population and vice verse varies widely according to patient-selection and age of the population. Estimates suggest that COPD is present in 10-40% of the patients with heart failure. Conversely, unrecognized heart failure is identified in approximately 20% of the patient with COPD. The impact of COPD on clinical outcome in patients with acute decompensated heart failure is unclear.

Methods:

This is an observational cohort study. Per national registry, acute heart failure is defined as either new onset heart failure or decompensation of chronic established heart failure with symptoms sufficient to warrant hospitalization.

The data related to the following variables would be collected:

age, gender, severity of heart failure (mild, moderate, and severe prior to admission), presence of dyspnea, peripheral edema, crackles, systolic and diastolic blood pressure (on admission and on discharge), heart rate (on admission and on discharge), oxygen saturation (on admission and discharge), blood urea nitrogen (on admission and discharge), serum creatinine (on admission and discharge), serum sodium (on admission and discharge), hemoglobin (on admission and discharge), red cell distribution width (on admission and discharge), electrocardiographic intervals (on admission and discharge), comorbidities (coronary artery disease, chronic kidney disease, atrial fibrillation, diabetes, hypertension, dyslipidemia, peripheral artery disease, COPD/asthma, left ventricular ejection fraction >40%. Medication use: angiotensin converting enzyme inhibitors, angiotensin receptor blockers, aspirin, metoprolol tartrate, metoprolol succinate, carvedilol, atenolol, amlodipine, Cardizem, clopidogrel, digoxin, diuretics, statins, nitrates, warfarin, non-steroidal anti-inflammatory drugs, hydralazine.

End-points:

  1. All cause in-hospital death and 2) length of hospital stay between heart failure patients with COPD and those with no COPD.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • COPDOther

    Also called chronic obstructive pulmonary disease

    COPD as diagnosed clinically or based on pulmonary function test showing post-bronchodilator forced expiratory volume in one second to forced vital capacity ratio of <0.7.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. In-hospital mortality

    Participants would be followed for the duration of hospital stay

    Measured: Average of 5-weeks

Secondary outcomes (1)
  1. Length of hospital stay

    Measured: Average of 5-weeks

Questions about this trial

What is this clinical trial studying?

An observational study of Disease, run by Mayo Clinic.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 11 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

In-hospital mortality (time frame: Average of 5-weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Mar 2020.
