Cardiology Research Unit

Stethoscope thumbnailThe Cardiology Research Unit's research involves contributing to multi-centre trials, including trials of new devices for coronary angioplasty, and clinical trials of new drugs for management of heart attacks, cholesterol levels, and arrhythmia.

Local research includes assessment of biomarkers as predictors of coronary stent re-stenosis after implantation.

The Research Unit is also performing a prospective study in patients with aortic valve disease evaluating what genes might be important in the development of narrowed heart valves in older persons.

Cardiovascular and respiratory physiology

Within the Department of Physiology severalRed veins thumbnail laboratories conduct research concerned with the regulation of cardiovascular and respiratory function in both health and disease.

Specific areas of interest include:

  • How hormonal, neuronal and intrinsic processes control the heart
  • Understanding the vasculature of the lungs
  • Describing calcium regulation of heart rhythms
  • Identifying pathogenic mechanisms operating in diseases such as obesity, diabetes, heart failure, hypertension and cardiac arrhythmia.

Centre for Free Radical Research

View of Christchurch city thumbnailWe're advancing health by exploring the biology of free radicals and antioxidants.

We are an internationally-recognised leader in the field of free radical research. We apply basic scientific knowledge to underpin research into the roles of free radicals and antioxidants in human health and disease.

Our mission is to discover how free radicals and antioxidants work inside the body and how this knowledge can be used to diagnose and treat human disease and maintain optimal health.

Centre for Translational Physiology

Bunch of electrodes thumbnailThe Centre for Translational Physiology (CTP) is a central research facility at the University of Otago, Wellington. It is designed to forge world-class research programmes that will accelerate the transfer of clinically-relevant scientific knowledge.

Translation of non-clinical research that results in real world clinical applications is a major challenge for biomedical researchers. With increasing sub-specialisation in both medical and basic biomedical disciplines, such knowledge transfer can become fragmented unless concerted efforts are made to promote their integration. A hallmark of those involved in the CTP is a willingness to collaborate on projects which utilise both scientific and clinical expertise. This is in recognition of the importance we believe translational physiological research provides in generating answers to clinical problems.

The following topics are of particular interest:

  • Energy and metabolism
  • Neurocritical care
  • Cardiovascular genetics
  • Exercise and environmental physiology
  • Clinical physiology and biomedical engineering
  • Paediatrics
  • Acute and chronic airways disease
  • Sleep medicine

Genetics Otago

DNA model thumbnailGenetics lies at the root of many human diseases. At Genetics Otago, we have a remarkable breadth of human genetics research studying both complex and single-gene diseases. As an example, researchers at the Cancer Genetics Laboratory are world-leaders in their field.

Our human developmental disease research provides an insight into how human embryos work, and how that is related to human health. We study both the genetics and epigenetics of human development and cell division.

Pharmocogenomics is another major area of research—this is a modern approach to understanding the side-effects of, and sensitivities to, drug treatments—by analysing the effect of a person's genes on their response to drugs.

Healthier Lives National Science Challenge

Family on a beach thumbnailThe Healthier Lives National Science Challenge is a national research collaboration dedicated to achieving healthier lives for all New Zealanders.

We are working on the prevention and treatment of four of New Zealand’s main non-communicable diseases:

  • Cancer
  • Cardiovascular disease
  • Diabetes
  • Obesity

Our mission is to deliver the right prevention to the right population and the right treatment to the right patient.

Heart Otago

Heart cells thumbnailHeart Otago is comprised of cardiovascular researchers and clinicians located at the University of Otago and Dunedin Hospital. The goal of the group is to expand upon traditional cell and animal models to better understand the molecular nature of cardiac disease in patients with heart disease and to translate the laboratory-based cardiovascular research into the clinical setting.

The strong link between fundamental researchers and clinicians allows the group to study cardiac disease from genetic mutations within a single protein, through tissue and animal models, to patients presenting with a range of cardiac anomalies.

Investigations involve a wide range of techniques including:

  • Electrophysiology
  • Cell imaging
  • Genetic and biomarker screening
  • Multicellular human tissue and whole animal heart function measurements
  • Human and animal in vivo cardiac function via echocardiography

Otago Vascular Diagnostics

Scanning equipment thumbnailWe are a team of vascular surgeons, technologists and research staff using various diagnostic investigations to research the causes and management of vascular conditions.

The unit provides clinical diagnostic services to the Southern District Health Board, and to the wider community, to assist in the diagnosis and treatment of vascular diseases such as:

  • Deep vein thrombosis
  • Carotid artery disease
  • Peripheral vascular disease
  • Aortic aneurysms
  • Varicose veins and venous ulcer

Our services include:

  • Medical imaging using ultrasound to capture real-time images of blood vessels and blood flow
  • Physiological testing to measure how well the vascular system is functioning both during exercise and at rest
  • Treatment of varicose veins and vascular malformations using endovenous laser therapy (EVLT) and sclerotherapy

The unit is part of the Vascular Research Group and works closely with other research groups at local, national and international levels.
