Cardiovascular disease, commonly referred to as heart disease, is a well-documented and thoroughly researched medical condition. Epidemiological investigations indicate that the annual mortality rate associated with cardiovascular disease continues to increase. Understanding the intricate interplay of risk factors associated with cardiovascular disease is pivotal in addressing this escalating public health crisis. In this paper, we aimed to explore the use of chi square to identify association between heart disease and some of the important risk factors such as gender, age, diabetes, heart attack before, body mass index (BMI), systolic blood pressure (SBP) and cholesterol level. The dataset was collected from the heart patient's records of Benghazi Cardiac Center – Libya. Among the 136 instances examined, 68 were identified as cases, representing individuals diagnosed with heart disease, while the other 68 served as controls, consisting of individuals without heart disease. Our results shows very interactive and significant pattern. It is found that significant variation between the different risk factors. It is important for both pre and post-heart patients to be increasingly mindful of these risk factors. In addition, this study can contribute to subsequent research efforts and will raise awareness among individuals about making healthier choices.............. Keywords:......
