Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Forty five eligible male patients with chronic heart failure secondary to ischemic heart disease were selected from National Heart Institute heart failure outpatient clinic , their ages ranged from 50-60 years old and their ejection fraction ranged from 30-40% ,they were randomly assigned into three groups :HIT Group: received High Intensity aerobic Training in the form of bicycle ergometer exercise for the lower limbs three times /week for three months.(n=15) MIT Group: received moderate Intensity aerobic Training in the form of bicycle ergometer exercise for the lower limbs three times /week for three months. .(n=15) LIT Group: received low Intensity aerobic Training in the form of bicycle ergometer exercise for the lower limbs three times /week for three months, Before and after intervention, the following measures were obtained: Echocardiograph parameter (EF%, and left ventricular internal dimension ) , prognostic biomarkers (proBNP), and quality of life .

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

50 years to 60 years (ADULT)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Ejection fraction
Time Frame: change from baseline to after 12 weeks
represents left ventricular function measured by pulsed echocardiography
change from baseline to after 12 weeks
pro-brain natriuretic peptide (proBNP)
Time Frame: change from baseline to after 12 weeks
biomarker for heart failure measured by analysis of venous samples drawn
change from baseline to after 12 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Minnesota Living With Heart Failure Questionnaire (MLWHF):
Time Frame: change from baseline to after 12 weeks
Questionnaire for measuring quality of life of heart failure patients
change from baseline to after 12 weeks

For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
