PhD thesis

Peter completed his PhD on the use of a novel imaging method to better examine coronary artery plaque and the optimal method of assessing heart stents. His thesis was published in 2009, following his studies at the Thoraxcenter in Rotterdam, the Netherlands, and at the Royal Brompton Hospital in London, UK. Peter's work on the use of optical coherence tomography (OCT) has been published worldwide and has contributed significantly to the field of interventional cardiology.

Peter's research on OCT has been particularly important in improving our understanding of coronary artery disease and developing better methods for assessing stents. He was the first cardiologist in Australia to introduce OCT to the country, and he has since pioneered and mentored many other centers in its use.

Overall, Peter's PhD thesis represents a significant contribution to the field of interventional cardiology, and his work on OCT has had a profound impact on our ability to diagnose and treat cardiovascular disease.

This comprehensive e-book is an indispensable resource for individuals undergoing or researching heart stents. It serves as a trusted reference for interventional cardiologists, fellows, and healthcare professionals, empowering patients with accessible knowledge and fostering engagement.

Nature Reviews Cardiology article

Optical coherence tomography

The article provides a review of the state-of-the-art in cardiac optical coherence tomography (OCT) and its application in coronary atherosclerosis research and clinical practice. Over the past two decades, OCT has been widely adopted for percutaneous coronary intervention optimization and has seen significant advances in understanding in vivo vascular biology in the past decade. The article highlights the need for accurate interpretation and understanding of OCT findings for appropriate use, and aims to serve as a standard reference for future research and clinical application. The review draws on contributions from experienced clinicians and investigators worldwide, who have made substantial contributions to OCT research in cardiac imaging

Computational modelling

Endothelial shear stress (ESS) plays a key role in the clinical outcomes in native and stented segments; however, their implications in bypass grafts and especially in a synthetic biorestorative coronary artery bypass graft are yet unclear. This report aims to examine the interplay between ESS and the morphological alterations of a biorestorative coronary bypass graft in an animal model. Computational fluid dynamics (CFD) analysis in this report provided sophisticated physiological information that complements the anatomic assessment from imaging enabling a complete understanding of biorestorative graft pathophysiology.

European Heart journal

World-first new technology

Most invasive coronary imaging modalities only provide anatomical information from which physiologic significance is inferred. Fractional flow reserve (FFR) and other physiologic indices of lesion severity are more reliable methods to identify physiologically significant lesions. Currently, accomplishing both anatomic and physiologic interrogation of an intermediate coronary stenosis requires the use of multiple devices within the coronary artery. This report highlights a breakthrough method using cardiac imaging and sophisticated engineering models to predict coronary artery disease severity led by Prof. Barlis and his research team.

other anti-anginals

When first-line therapies for angina, such as beta blockers, calcium channel blockers, and nitrates, prove inadequate or are not well-tolerated, second-line therapies may be considered.
Perhexiline is a unique medication that enhances the heart's ability to utilize fatty acids for energy, reducing its reliance on oxygen and lowering oxygen demand. This action helps improve blood flow and alleviates chest pain in some patients with refractory angina.
Nicorandil is another second-line option with a dual mechanism of action. It opens potassium channels in smooth muscle cells, causing vasodilation and enhancing coronary blood flow. Additionally, nicorandil also stimulates nitric oxide release, further dilating blood vessels and reducing heart workload.
Trimetazidine is an anti-ischemic agent that improves cardiac efficiency by enhancing glucose metabolism and shifting the heart's energy production to a more oxygen-efficient process. As second-line therapies, these medications offer alternative approaches for managing angina in individuals who do not respond adequately to first-line treatments or those experiencing side effects from other medications.

lipid lowering therapies

Lipid-lowering therapies play a critical role in managing coronary artery disease (CAD), a condition characterized by the narrowing of blood vessels that supply the heart. Among the most commonly discussed and debated classes of medications are statins, which effectively reduce cholesterol levels and are widely prescribed to lower the risk of cardiovascular events. Alongside statins, other medications like ezetimibe, fibrates, and niacin are also utilized to target specific aspects of lipid metabolism, such as cholesterol absorption, triglyceride levels, and raising high-density lipoprotein (HDL) cholesterol. Additionally, the introduction of medications that inhibit PCSK9, an enzyme involved in cholesterol metabolism, has provided a promising new approach to further lower LDL cholesterol levels. These PCSK9 inhibitors, such as Repatha (evolocumab), have shown significant efficacy in reducing LDL cholesterol levels in patients with CAD, especially for those who may not respond well to traditional therapies.


Nitrates are widely used to treat angina and provide quick relief for chest pain. Commonly available in the form of sublingual sprays or tablets, patches, and long-acting tablets, nitrates work by dilating blood vessels, allowing for increased blood flow and reduced resistance. This dilation eases the heart's workload, leading to a decreased demand for oxygen and prompt alleviation of angina symptoms. Sublingual nitrates act rapidly and are often used to provide immediate relief during angina attacks, while patches and long-acting tablets are employed for preventive purposes. However, nitrates may cause side effects such as headaches, dizziness, and flushing, which usually subside over time.

calcium channel blockers

Calcium channel blockers, including amlodipine, felodipine, cardizem (diltiazem), and verapamil, are commonly prescribed for the treatment of angina. These medications work by inhibiting the influx of calcium into the muscle cells of the heart and blood vessels, leading to their relaxation. As a result, blood vessels widen, promoting improved blood flow and reduced blood pressure. In the context of angina, this relaxation decreases the heart's workload, lowering the demand for oxygen and alleviating chest pain. Calcium channel blockers offer a valuable treatment option for individuals with angina, but it is essential to be aware of potential side effects, which may include headaches, dizziness, flushing, and ankle swelling.

Beta blockers

Beta blockers, such as metoprolol, propranolol, atenolol, carvedilol, and bisoprolol, play a crucial role in treating angina. By blocking certain receptors in the heart, they effectively reduce heart rate and the force of contraction, thereby easing the heart's workload. This mechanism of action leads to a decreased demand for oxygen, making beta blockers highly effective in relieving chest pain associated with angina. As with any medication, it's important to consider potential side effects, including tiredness, worsened asthma, erectile dysfunction in some males, and more vivid dreams during sleep. Consult your healthcare provider to determine the suitability of beta blockers for managing your angina and overall heart health.

Anti-platelet Medications

Anti-platelet medications play a crucial role in preventing blood clot formation, reducing the risk of serious cardiovascular events such as heart attacks and strokes. Among the widely used anti-platelet drugs are aspirin, clopidogrel, and ticagrelor.

Aspirin: This well-known medication inhibits platelet activation, making it less likely for platelets to stick together and form clots. Aspirin is commonly used for primary and secondary prevention of heart attacks and strokes.

Clopidogrel: As a potent anti-platelet agent, clopidogrel works by blocking specific receptors on platelets, preventing them from aggregating. It is often prescribed to patients with acute coronary syndrome, those undergoing stent procedures, and for some cases of peripheral arterial disease.

Ticagrelor: Ticagrelor is another effective anti-platelet drug that works by inhibiting platelet activation. It is used in acute coronary syndrome, often given alongside aspirin to reduce the risk of heart-related events.
