I. Introduction
Heart disease is the world's number one killer globally, says the WHO [1]. Factors including diabetes, hypertension, abnormal cholesterol levels, an abnormal pulse rate, and so on make it harder to detect cardiovascular disease. According to [2], it is found that the symptoms of CVD vary from gender to gender. For example, male members are more likely to suffer from chest pain, whereas female patients have some other symptoms related to chest discomfort, such as shortness of breath and nausea [3]. As opined by [4], professionals use different classification techniques to predict CVD early by analysing current symptoms. The existing system of predicting cardiovascular disease is depicted in the below part.
