Speech Title: Study of Advanced AI Techniques for the Detection of Myocardial Infarction ECG Signals in Clinical Settings

Abstract: Coronary artery disease occurs when plaque is accumulated in the walls of the artery. This causes the artery to narrow, reducing blood flow to the heart. Coronary artery disease is globally identified as the most predominant and lethal cardiovascular disease. Furthermore, undiagnosed coronary artery disease may progress and lead to complications such as myocardial infarction and congestive heart failure. Hence there is a compelling need for the prompt and unerring detection of coronary artery disease, myocardial infarction, and congestive heart failure using automated systems. The electrocardiogram (ECG) is the most preferred method of detecting cardiovascular diseases as it is easily available and economical compared to imaging methods. Hence, this talk summarises the development of advanced models using ECG signals for the detection of coronary artery disease, myocardial infarction, and congestive heart failure, focusing on the detection of myocardial infarction. This work contributes to the medical field as it offers some level of explainability of the inner workings of the deep models that clinicians may relate to. The reliability of the developed deep model used in healthcare applications such as emergency diagnosis of different types of myocardial infarction contributes significantly to clinicians. The presentation will include 3 parts:
1) the development of convolutional neural network (CNN) and GaborCNN (with a unique Gabor layer) models for rapidly classifying coronary artery disease, myocardial infarction, congestive heart failure, and healthy ECG signals is discussed. The ECG signals which were acquired from the Physikalisch- Technische Bundesanstalt (PTB) database, were fed to the two models for classification. The GaborCNN was affirmed to be the better model for the classification task due to its high overall accuracy of 98.74% and lower computational demand. We believe this is the first study to integrate the Gabor filter into the CNN model to automatically classify normal, coronary artery disease, myocardial infarction, and congestive heart failure classes using ECG signals.
Despite the surge in the development of robust models for the automated detection of cardiovascular diseases, these are often not trusted by clinicians due to the lack of explainability of models’ mechanisms. Hence,
2) the development of the CNN and DenseNet models with the application of an advanced and unique GRAD-CAM technique to both models’ output will be briefly discussed. ECG beats were extracted from the healthy and ten myocardial infarction classes using the R peak detection algorithm and fed to the developed CNN and DenseNet models. Application of the GRAD-CAM technique enabled visualization of ECG leads and portions of ECG waves that influenced the models’ predictive decisions. DenseNet was identified as a better model due to its low computational complexity and higher classification accuracy of 98.9% due to feature reusability. Lead V4 was the most activated lead in both models. The DenseNet model with the Grad-CAM technique enables clinicians to determine the type of myocardial infarction based on explainability and, thus, has the potential to boost clinicians’ confidence in using it in hospital settings. This is exciting to report features that influenced the classification decisions of deep models for multiclass classification of myocardial infarction and healthy ECGs.
Current diagnostic models for cardiovascular diseases have been primarily developed using public databases and are thus unsuitable for hospital settings, where the uncertainty of models is predominant.
3) a unique Dirichlet DenseNet model was trained with pre-processed myocardial infarction ECG signals and tested with noisy myocardial infarction signals. The predictive entropy was used as an uncertainty measure to determine the misclassification of normal and myocardial infarction signals. The misclassification of signals was determined based on the computation of four uncertainty metrics; uncertainty sensitivity, specificity, accuracy and precision. The proposed method demonstrates that the developed model is reliable as it is able to convey when it is not confident in the diagnostic information its presenting, having the potential to make a significant contribution to clinicians, especially in emergencies such as urgent diagnosis of myocardial infarction. We have explored uncertainty quantification of a deep model using multi-class myocardial infarction ECG signals.
In summary, we believe the models proposed in the above 3 parts have great potential to contribute significantly to healthcare in areas such as the emergency diagnosis of acute myocardial infarction.

Speech Title: The Road Ahead: Exciting Prospects in Precision Oncology

Abstract: Precision oncology has revolutionized cancer treatment by tailoring therapies to individual patients based on their unique molecular profiles. This presentation explores the promising prospects in precision oncology, with a particular focus on liquid biopsy and hallmarks of cancer.
Liquid biopsy has emerged as a non-invasive method for monitoring tumor dynamics and detecting genetic alterations. It enables the analysis of circulating tumor DNA, RNA, and proteins, providing real-time information on tumor evolution, treatment response, and the emergence of resistance. The potential of liquid biopsy extends to early cancer detection, treatment monitoring, and personalized therapy selection. Furthermore, the diagnostic and therapeutic potential of extracellular vesicles, which serve as carriers of nucleic acids, proteins, and metabolites reflecting the molecular characteristics of tumors, holds significant promise for precision oncology.
Precision oncology capitalizes on the significant targets presented by the hallmarks of cancer, which include sustained proliferation, evasion of growth suppressors, resistance to cell death, and attainment of replicative immortality. Therapeutic interventions aimed at disrupting these hallmarks have demonstrated promising outcomes, prompting ongoing research to identify novel targets and develop effective treatments. Within this evolving landscape, the microbiome has emerged as a novel dimension within the hallmarks of cancer. Comprising trillions of microorganisms inhabiting the human body, the microbiome exerts influence over diverse aspects of cancer development and contributes to the discovery of new therapeutic targets.
In conclusion, precision oncology holds immense promise in transforming cancer care. Advances in liquid biopsy, exploration of the hallmarks of cancer, and targeting specific mutations pave the way for more effective and personalized cancer treatments.
