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
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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 looked at whether circuit training, with or without added arm and leg resistance exercises, could help people who had heart surgery breathe easier at night and improve their daily function. Sixty adults aged 35 to 65 who had bypass surgery 3 to 6 months earlier took part. The goal was to see if these exercises could reduce nighttime breathing problems and boost endurance.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
circuit training exercises with and without upper and lower limb resistance training using weights and therapeutic bands
What this could lead to
If it works, this could point toward a simple exercise program to help heart surgery patients breathe easier at night and walk farther.
What could go wrong
This is a small, completed study with only 60 participants, so results may not apply to everyone. Exercise programs require ongoing effort and may not work for all patients.

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

Inclusion Criteria: * • Adult CABG surgery candidates aged between 35 and 65 years who underwent uncomplicated CABG surgery within past 3-6 months. * No history of pre-existing pulmonary disease. * Clinically stable cardiac status and approval for participation in phase-II cardiac rehabilitation from the cardiac surgeon. * Patients that presented with the symptoms of mild to moderate levels of paroxysmal nocturnal dyspnea (PND). (38) * Willingness and availability to participate in the phase-II cardiac rehabilitation program for the study duration. * Physical ability to perform both upper and lower limb strength training exercise. * Absence of pre-existing severe orthopedic limitations that could interfere with the exercise performance. Exclusion Criteria: * Uncontrolled hypertension, cardiac arrhythmias or any unstable cardiovascular complication that was an absolute contraindication to participate in clinical exercise program. * Severe pre-existing pulmonary conditions such as COPD or Asthma that could interfere with exercise capacity. * Severe orthopedic limitations such as arthritis, recent fractures and sternal site infections post-surgery. * Neurological complications, including stroke, severe neuropathy, balance and coordination abnormalities that could impede physical performance. * Cognitive impairments that may possibly affect the ability to understand and follow the exercise protocols. * Participation in some other structured rehabilitation program within the past month.
