Research

A major role of the Integrative Cardiac Wellness Group is to understand the effectiveness and feasibility of new models of integrative, personalised health care. To do this, we undertake research and evaluate the integrative servfices provided.

We are a foundation National Institute of Complementary Medicine (NICM) Collaborative Research Centre

Current research projects

  • Detecting changes in INR levels after taking Fish Oil and Coenzyme Q10 supplements by elective cardiothoracic surgical patients on Warfarin

In November we commenced a prospective clinical study to determine whether international normalized ratio (INR) levels of long-term warfarin users will change after commencing fish oil supplements together with coenzyme Q10 (CoQ10). Warfarin is an anticoagulant (blood thinning) medication and INR levels are a measure of blood clotting. This study will further investigate the safety of these supplements.

Research conducted overseas and at The Alfred has shown that patients taking CoQ10 and fish oil supplements do not have a higher risk of bleeding compared to patients not taking the supplements. Despite this, some confusion still exists in the literature which we aim to clarify with this study. In our annual audits of our integrative cardiac wellness program (ICWP) we examine a number of postoperative outcome measures including peri- and postoperative bleeding and have found no significant increase in the frequency of serious bleeding events. Now we wish to focus more closely on people taking warfarin. The benefits of these supplements when used by cardiac surgery patients have already been demonstrated in several clinical trials, including research conducted at The Alfred Hospital.

Supplements are being supplied free-of-charge by FIT Bioceuticals.

  • Testing vitamin D and zinc status in cardiac surgery patients and the effects on clinical ICU outcomes.

This investigator initiated, open label study recruited 80 elective cardiac surgery patients at The Alfred in 2011/2012 and tested their vitamin D and zinc levels before surgery. The primary aims of this study were to identify the prevalence of vitamin D and zinc deficiency in our cardiac surgery patients and whether low pre-surgery levels had a negative impact on intensive care unit (ICU) outcomes.
We will also look at whether nutrient deficiency is associated with the use of any particular medication, such as hypertensive medication.

Patients found to have insufficient vitamin D before surgery were given oral vitamin D supplements and their blood levels re-checked 6 weeks after being discharged to confirm their levels have gone back towards normal.


Patients found to have zinc deficiency will were notified of the result and encouraged to consume more zinc-rich foods.


Supplements are being supplied free-of-charge by Blackmore’s.
Results of this study are currently being analysed.

Previous research projects

  • Evaluating effects of metabolic supplements in cardiac surgery patients.

This project which built on previous research conducted at the Alfred Hospital which showed fish oils and metabolic supplements (key antioxidants) reduced coronary artery bypass graft (CABG) surgery patients' risk of atrial fibrillation, a common complication after surgery and reduced their time in hospital. The most recent audit demonstrated that use of these supplements before surgery led to a reduced requirement for positive inotropic medication (cardiac function support) after surgery in both valve surgery and CABG patients. Importantly, we confirmed the supplements were safe to use and did NOT increase the risk of a serious bleeding event. 

  •  An observational study to examine the physiological mechanisms associated with cognitive impairment in heart failure patients
This study found that oxidative stress and inflammation are associated with cognitive impairment in older heart failure patients.
Patients were recruited from the Alfred Hospital Heart Centre, and the healthy control group was recruited from the general public and tested at Swinburne University's Brain Sciences Institute.

Biological factors including oxidative stress, inflammation, cerebral blood flow and arterial stiffness were also recorded. Relationships between these biological measures and cognitive performance are currently being analysed.

Findings from this study may assist with devising appropriate interventions to improve cognitive performance in heart failure patients.

  • Evaluating stress reduction therapy in cardiothoracic surgical patients.

This study compared the effects of massage delivered by trained massage therapists on the wards after surgery to additional undisturbed time during the day. Patients were randomly selected to receive either massage therapy or ‘quiet time'.

This project aimed to determine whether massage therapy reduces anxiety, pain, muscle tension, blood pressure and heart rate.

The project was completed in January 2011. It was found that the massage therapy significantly reduced pain, anxiety and muscular tension and improved relaxation and satisfaction after cardiac surgery.

  •  A randomised controlled study investigating natural supplements in total knee replacement patients.

This study compared fish oil and metabolic supplements (key antioxidants) to placebo (dummy capsules) to see if treatment reduced complications and improved patients' quality of life after surgery. It involved patients at Sandringham, Cabrini and Alfred hospitals.
