Heart disease in an aging population has resulted in heart surgery being offered to older and more frail patients. Frail patients which make up more than 50% of patients currently undergoing heart surgery are vulnerable to having long-recovery times after surgery, greater loss of independence (i.e. being admitted to a nursing home), experience more depression and anxiety, and have a worse quality of life. In fact, nearly 10% of frail, older adult patients die within 30 days after their heart surgery. The Investigators previous study found that weight-loss and poor muscle strength (i.e. weakness) of frail patients can lead to a worse recovery after heart surgery. Furthermore, inadequate nutrition (aka. malnutrition which is defined as an unintentional, nutritional intake imbalance (not necessarily a decreased intake) before an operation can lead to a vicious cycle of muscle loss causing more frailty, a desire to eat less leading to more muscle loss and increased frailty. At present there is no process to address this important issue in older adults undergoing heart surgery. The Investigators propose to study a practical, real-world, treatment plan that focuses on good nutrition to prevent muscle loss and reduced frailty in vulnerable heart surgery patients.
To enhance recovery in vulnerable older adults (aged 60 years or older) undergoing major heart surgery. The Investigators seek to reduce the stress of heart surgery on the body by providing muscle-building nutrition supplements (with leucine-rich proteins) at key time-points during the patients' journey.
Objectives of this study:
In a two-centre clinical trial, frail older adults (patients who are at risk of a long recovery) undergoing major heart surgeries will receive nutrition supplements up to 2 weeks prior to surgery, during post-op recovery in hospital, and for the 8 weeks following hospital discharge. Prior to surgery, all patient in the study will consume a carbohydrate supplement in order to help with nausea symptoms post surgery, glycemic control and GI function. The Investigators will ask 150 (pre)frail patients before their heart surgery to participate. Patient who are 60 years of age or older who agree to be in the study will be randomly selected (75 patients in each group) to receive the nutrition protein shakes or a placebo (a shake without the special protein). In addition to how long a patient needs to stay in hospital after their heart surgery, The Investigators will measure levels of frailty (by different tests of muscle strength), overall nutrition, health related quality of life after surgery as well as mood and anxiety at 2 and 6 months after hospital discharge.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Protein Supplementation | Experimental | The intended intervention consists of a leucine-rich protein-caloric supplement provided by the Enhanced Medical Nutrition®. The product contains 25 g protein and 3 g Leucine per serving (total caloric value: 160 Kcal.) to be re-constituted and consumed twice daily for a minimum of 2 weeks pre-procedure, twice daily during post-operative recovery and 2 times daily for 8 weeks after the patient is discharged home (Appendix A). |
|
| Placebo Supplementation | Placebo Comparator | Enrolled patients allocated to the control group will receive the same supplementation schedule as well as compliance verification; however, they will receive a placebo product with no supplemented protein (no nutritional benefit). |
