Micro-AF – harbinger of AF?

29th November 2021, Dr Chee L Khoo

One of our biggest fears is missing an atrial fibrillation (AF) and patient is discharged from hospital following their first embolic stroke. Almost all the automatic sphygmomanometers do not check for cardiac rhythm and I make it a point to put a finger on the pulse each time to make sure patients are in sinus rhythm.…

PCSK9 inhibitors on the PBS – another kid on the block

13th November 2021, Dr Chee L Khoo

PBS Authority for PCSK9 inhibitors

The authority to prescribe a PCSK9 inhibitors for patients with resistant hyperlipidaemia under the PBS continues to be pretty complicated. We tried to simplified those numerous criteria back in December 2020 here when the criteria were “loosened” somewhat. This has facilitated my prescription of this important drug in those patients who have really, really high cardiovascular risk.…

3rd dose for the non-immunocompromised – is it necessary?

13th November 2021, Dr Chee L Khoo

booster shots?

The success of mass vaccination is demonstrated by the dramatic reduction in case numbers and deaths from Covid-19 infections since the introduction of the covid-19 vaccines worldwide. Countries such as UK, USA, Israel and Singapore started and completed their campaign very early in 2021. Their success has been challenged by the increasing breakthrough in those countries since June 2021.…

The skinny T2D – what do we have to watch out for?

29th October 2021, Dr Chee L Khoo

Which T2D?

Traditionally, we think of diabetes as either type 1 or type 2. That’s mainly because type 1 diabetes (T1D) was discovered first and type 2 diabetes (T2D) came later. Everything that was not T1D was T2D. T1D is an auto immune disease characterised by the death of the beta cells leading to insulin deficiency while T2D is a disease of both insulin resistance and insulin deficiency.…

Spectrum is now at Sydney South West Private Hospital

25th October 2021, Spectrum Medical Imaging

Sydney Southwest Private Hospital

One of the very few beneficial things over the lockdown period is the easier availability of radiological services. Most radiological practices have reported reduction in throughput during the recent outbreaks. As we emerge from the lockdown, referrals for medical imaging are increasing and with the increase, an increasing wait time for services is happening.…

Dyslipidaemia in the young – who should we suspect?

24th October 2021, Dr Chee L Khoo

Last fortnight we explored the disease burden in patients who have high lipids from a very young age and the effect on their future cardiovascular risk. This consideration allows us to think about who should be aggressively treated and whom we can just safely watch, at least for a few years. It would be nice to be able identify who we should screen for high lipids from a young age so that we can start lifestyle measures early.…

Covid-19 vaccine booster for the immunocompromised – who is eligible?

Booster jab, anyone?

10th October 2021, Dr Chee L Khoo

Updated 17th October 2021

You would have caught a bit of the announcement that some people may be due a Covid-19 vaccine booster. As usual, the announcement is not precise or detailed enough and now everyone is confused whether they are the intended target group for the booster. It is not a call to boosters for most vaccinated people.…

Oral anti-viral against Covid-19 – how does it work?

5th October 2021, Dr Chee L Khoo

The media is abuzz with this wonder oral drug for treatment of Covid-19 infection by Merck, Sharp & Dohme (MSD). We are talking about Molnupiravir, the broad spectrum anti-viral agent which inhibits replication of not just Covid-19 but many other viruses in cell culture. What is Molnupiravir? Who amongst the patients with Covid-19 infections will benefit from the drug?…

Dyslipidaemia in young adults – should we be treating?

2nd October 2021, Dr Chee L Khoo

cumulative high lipids

We generally see two categories of patients with high lipids, one who had normal lipids earlier on in life but developed high lipids later in life because of modern living and one whose lipids were already high when they were young (and slim and fit). Most of the scientific studies linking high lipids with cardiovascular (CV) events look at lipid levels at a snap point in time, at enrolment and the follow up period just aren’t long enough.…

Dapagliflozin Product Information – why a tiny omission means a lot?

25th September 2021, Dr Chee L Khoo

small omission

SGLT2 inhibitors (SGLT2i) have been shown to improve outcomes in patients with type 2 diabetes (T2D) and high cardiovascular risks as well as in patients with chronic kidney disease and heart failure regardless of diabetes status and independently of blood glucose levels or HbA1c. There is a little bit of a “catch” though, the eGFR.…

CT Angiogram – who does Medicare cover?

23rd September, Spectrum Medical Imaging

CT angiogram

We all know the restrictions we all have in who we can order an ECG, stress test or stress echocardiogram for since the change in Medicare rebates some months ago. I am confused about the various eligibility criteria. You know what happens when are all confused? We stop ordering them to the detriment to patient care.…
