Brief Summary

The PREHAB study is a clinical trial where frail patients waiting for heart surgery are randomly chosen to either receive the current standard of care or to participate in an 8-week exercise/education program at a community-based cardiac rehabilitation facility. Patients can wait for elective heart surgery for as long as 3-4 months. During this time, individuals are often fearful of making things worse, causing them to stop being active and further deteriorate their physical condition. This wait period presents a potential opportunity for health care providers to engage the patient to take control of their self-managed care prior to surgery with the intent of improving post-surgical outcomes. Patients randomized to the PREHAB intervention group will participate in supervised exercise twice per week in a program designed to improve physical functioning and exercise capacity. The investigators hypothesize that the PREHAB program for frail elderly patients awaiting an elective cardiac surgery will reduce frailty, improve exercise capacity, improve physical activity behaviour, improve in-hospital outcomes, improve clinical outcomes 3 months and 1 year postoperatively, and improve overall quality of life.

Study Arms (2)

Standard Care

NO INTERVENTION

Patients in the standard care group will receive care as is currently delivered to patients awaiting cardiac surgery at each site. At present, patients are advised to rest and participate in very light intensity physical activity while awaiting surgery. At 1-2 weeks prior to their scheduled surgical date, the patient attends a single three hour cardiac pre-assessment with a nurse practitioner and cardiac anesthesiologist. In addition, a cardiac nurse counsels each patient on healthy behaviors (e.g. smoking cessation, diet, exercise).

Prehab Intervention

EXPERIMENTAL

Patients in the Prehab group will receive, in addition to the standard of care, an eight-week comprehensive exercise therapy and education program at a community-based CR facility. Patients will be asked to complete at least two sessions of supervised, structured exercise class plus have the option to attend one additional exercise class per week for eight-weeks, with progression to a moderate to high-intensity interval program based on the supervised assessment of the patient's capabilities. Prehab participants will also attend four education sessions on topics such as risk factor reduction, medication use, cardiovascular physiology, smoking cessation, healthy eating, exercise, and stress management and promotion of self-managed care.

Eligibility Criteria

Age60 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients aged 60 years and older, undergoing elective isolated coronary artery bypass grafting (CABG), aortic valve repair/replacement for moderate aortic stenosis or severe regurgitation, mitral valve repair/replacement for moderate stenosis or severe regurgitation or combined CABG/valve procedures
  • Patients with Clinical Frailty Score (CFS) ≥3 (vulnerable) and \< 7 (8 = very severely frail, approaching end-of-life or 9 = terminally ill) at time of acceptance for cardiac surgery
  • Patients with an estimated ≥ 6 week wait time

You may not qualify if:

  • Patients who have unstable or recent unstable cardiac syndrome as defined by:
  • Severe heart failure (NYHA IV) or angina (CCS class IV) symptoms
  • Critical left main (LM) coronary disease
  • Hospitalization for arrhythmias, congestive heart failure or acute coronary syndrome prior to randomization
  • Patients who have severe left ventricular obstructive disease as defined by:
  • Severe aortic or mitral stenosis (aortic or mitral valve area \<1.0cm2 or mean gradient \> 40 mmHg or \> 10 mmHg respectively)
  • Dynamic left ventricular (LV) outflow obstruction
  • Patients who have demonstrated exercise induced ventricular arrhythmias or have experienced a recent hospitalization for arrhythmias
  • Patients who have cognitive deficits that would preclude rehabilitation
  • Patients who have physical limitations that would preclude rehabilitation
  • Patients who are unable to attend the Prehab program

Limitations and Caveats

1. Recruitment was only 89 participants from an expected sample size of 244 participants. This was a major limitation regarding data analysis. 2. Short cardiac surgery waitlists (i.e. surgery in less than 4 weeks) were impactful to study recruitment and intervention delivery
