I. Introduction
Heart disorders are a major global public health concern that account for a large portion of fatalities. According to the WHO, 17.9 million deaths worldwide are caused by cardiovascular illnesses each year, or 31% of all fatalities [1]. Effective disease prevention and management depend on the early detection and precise prediction of CVDs. Many risk factors for heart conditions, including diabetes, high blood pressure, smoking, high cholesterol, and obesity are blamed for the rise in heart conditions in the general population [2]. The Framingham Risk Score and other conventional risk assessment models, in particular when applied to populations with diverse ethnic and genetic origins, have limitations in their ability to predict the risk of CVDs [3]. By combining big and complicated datasets from many sources, machine learning (ML) techniques can be utilised to increase the precision of heart disease risk prediction [4]. In order to forecast heart failure disease, Alotaibi (2019) [5] proposed a machine learning model that makes use of demographic, clinical, and laboratory data. In order to forecast cardiac illness, Ali et al. (2020) [6] created a smart healthcare monitoring system that combines ensemble deep learning with feature fusion. The clinical uses of ML in cardiovascular disease and its connection to cardiac imaging were examined by Al'Aref et al. (2019) [7]. In a research study with 423,604 participants from the UK Biobank, Alaa et al. (2019) [8] employed automated machine learning to predict cardiovascular disease risk. These studies show the potential of ML to increase the precision and effectiveness of heart disease prediction. Then there are various studies that offer principal component analysis (PCA) and other statistical methods as feature selection methods. For instance, Garate-Escamila et al. (2020) [9] developed feature selection and PCA-based classification models for the prediction of cardiac disease. The most recent developments in cardiac disease prediction using ML and image fusion were evaluated by
