Dr Kgomotso Moroka, Acting HOD: Cardiology in the UFS Faculty of Health Sciences, recently graduated from Maastricht University with a Diploma of Advanced Studies in Cardiac Arrhythmia Management (DAS-CAM).

A staff member from the University of the Free State (UFS) is hopeful her newly acquired skills and knowledge, following her graduation with a Diploma of Advanced Studies in Cardiac Arrhythmia Management (DAS-CAM) and completion of a electrophysiology fellowship, will contribute to the improvement of cardiovascular services in the Free State and Sub-Saharan Africa.

Dr Kgomotso Moroka, the Acting Head of Department (HOD) for Cardiology in the UFS Faculty of Health Sciences, recently graduated with a DAS-CAM in June 2023. This distinctive postgraduate programme is offered by Maastricht University in collaboration with the European Heart Rhythm Association and the European Society of Cardiology. This is a two-year programme and Dr Moroka was part of the third cohort which comprised 32 electrophysiologists selected from over 20 countries worldwide.

Her achievement places her as the sole   DAS-CAM graduate in Sub-Saharan Africa and the Free State region. 
Electrophysiology, which studies the electrical influences and patterns of the heart is vital for treating patients with abnormal heartbeats caused by irregularities in the heart’s electrical pathway, resulting in either unusually slow or fast heartbeats.

Seizing a valuable opportunity

Dr Moroka emphasises that currently, there is a lack of electrophysiology services provided in both the public and private sectors within the Free State. She therefore anticipates that her newly acquired skills and knowledge will play a pivotal role in enhancing and improving the cardiovascular services offered in the province. She is also optimistic about contributing to the establishment of a department dedicated to Electrophysiology Training. 

“I could not pass up the opportunity to engage with, learn and gain insights from seasoned world-class great minds of electrophysiology, who write the books we read and the very guidelines that we utilize in our daily practices. There was also an opportunity to be guided in research and the state-of-the-art cardiac clinical electrophysiology while also obtaining insights into how to develop a cardiac arrhythmia centre, biostatics, health economics, leadership skills and health technology assessment,” Dr Moroka explains regarding her motivation to enrol in the program. 

“It was a challenging and exciting program that allowed participants to engage with the world-renowned experts in electrophysiology not only on a professional but also personal level. This program served not only to educate participants on clinical cardiac electrophysiology but served to empower us to fulfil roles as future leaders in electrophysiology and in our day-to-day roles,” she continued.

Addressing the diverse burden of cardiac diseases

Dr Moroka believes that this qualification will significantly contribute to local efforts to establish and develop a much-needed unique service, thereby advancing her career development locally and on the international platform. This qualification enables her to expand her clinical research pursuits on multiple fronts.

Dr Moroka underscores the substantial burden of ischemic heart disease with the associated risk factors such as uncontrolled high blood pressure, diabetes, elevated cholesterol levels and smoking. “There is a measurable burden of heart failure and valvular heart disease. In addition, from the research that we hope to embark upon, we hope to clearly define the burden of rhythm problems such as atrial fibrillation and other arrhythmias which are serious conditions. With the available skills and knowledge, we can begin to offer alternative adjunctive treatment that would have a significant positive effect on the morbidity and/or mortality of our patients.”

Dr Moroka points out that with the advent and advances in machine learning and digital health technology, we are in an exciting era of possibilities of obtaining valuable biological data and biometric parameters that would assist in the reduction of risk and prevention of a diversity of cardiovascular diseases and to guide clinical practice guidelines. 

“The current focus is risk reduction, prevention of cardiovascular diseases and the establishment and development of personalized health care, with a growing interest in cardiovascular genetics and gene therapy.  Who knows what the future will bring, but for now the focus is to work towards good health and disease alleviation,” she says.

In August 2017, the Boyden Observatory in Bloemfontein played a major role in obtaining optical observations of one of the biggest discoveries ever made in astrophysics: the detection of an electromagnetic counterpart to a gravitational wave event.
 
An article reporting on this discovery will appear in the prestigious science journal, Nature, in October 2017. Co-authors of the article, Dr Brian van Soelen and Hélène Szegedi, are from the Department of Physics at the University of the Free State (UFS). Both Dr Van Soelen and Szegedi are researching multi-wavelength astronomy.
 
Discovery is the beginning of a new epoch in astronomy
 
Dr van Soelen said: “These observations and this discovery are the beginning of a new epoch in astronomy. We are now able to not only undertake multi-wavelength observations over the whole electromagnetic spectrum (radio up to gamma-rays) but have now been able to observe the same source in both electromagnetic and gravitational waves.”
 
Until recently it was only possible to observe the universe using light obtained from astronomical sources. This all changed in February 2016 when LIGO (Laser Interferometer Gravitational-Wave Observatory) stated that for the first time they had detected gravitational waves on 14 September 2015 from the merger of two black holes. Since then, LIGO has announced the detection of two more such mergers. A fourth was just reported (27 September 2017), which was the first detected by both LIGO and Virgo. However, despite the huge amount of energy released in these processes, none of this is detectable as radiation in any part of the electromagnetic spectrum. Since the first LIGO detection astronomers have been searching for possible electromagnetic counterparts to gravitational wave detections. 
 
Large international collaboration of astronomers rushed to observe source
 
On 17 August 2017 LIGO and Virgo detected the first ever gravitational waves resulting from the merger of two neutron stars. Neutron star mergers produce massive explosions called kilonovae which will produce a specific electromagnetic signature. After the detection of the gravitational wave, telescopes around the world started searching for the optical counterpart, and it was discovered to be located in an elliptical galaxy, NGC4993, 130 million light years away. A large international collaboration of astronomers, including Dr Van Soelen and Szegedi, rushed to observe this source.
 
At the Boyden Observatory, Dr Van Soelen and Szegedi used the Boyden 1.5-m optical telescope to observe the source in the early evening, from 18 to 21 August. The observations obtained at Boyden Observatory, combined with observations from telescopes in Chile and Hawaii, confirmed that this was the first-ever detection of an electromagnetic counterpart to a gravitational wave event. Combined with the detection of gamma-rays with the Fermi-LAT telescope, this also confirms that neutron star mergers are responsible for short gamma-ray bursts.  
 
The results from these optical observations are reported in A kilonova as the electromagnetic counterpart to a gravitational-wave source published in Nature in October 2017.
 
“Our paper is one of a few that will be submitted by different groups that will report on this discovery, including a large LIGO-Virgo paper summarising all observations. The main results from our paper were obtained through the New Technology Telescope, the GROND system, and the Pan-STARRS system. The Boyden observations helped to obtain extra observations during the first 72 hours which showed that the light of the source decreased much quicker than was expected for supernova, classifying this source as a kilonova,” Dr Van Soelen said.
