Chief among these challenges are health-related issues. Among these health problems, heart diseases stand out as the leading cause of mortality. Consequently, the early diagnosis of heart diseases plays a pivotal role in mitigating mortality rates and enhancing people's overall quality of life. This study aims to employ machine learning algorithms to enhance the early detection capabilities of heart disease. A dataset comprising the health records of 253,680 patients with heart disease is analyzed using five distinct machine learning algorithms: Logistic Regression, K-Nearest Neighbors Classifier, Decision Tree Classifier, Naïve Bayes, and Linear Support Vector Machine (Linear SVM). The dataset is partitioned, with 80% allocated for training the algorithms and the remaining 20% for testing. Furthermore, the study's evaluation employs four different metrics: accuracy, precision, recall, and the F1-measure. Initially, early diagnosis of heart disease is attempted using the complete set of features in the dataset. However, this approach results in excessive costs and time consumption. Subsequently, a feature reduction process is implemented to optimize resource utilization, yielding an improved early detection rate. The research findings indicate that Logistic Regression outperforms the other algorithms, achieving the highest success rate with an accuracy score of 90.67%. These research results underscore the substantial contribution of machine learning algorithms to the early detection of heart  \ndisease, ultimately enhancing the quality of life for individuals.

It is well known that artificial intelligence is one of the most important components of computer programs. This has attracted the attention of many researchers, educators and even many companies. Today, the integration of artificial intelligence into healthcare is the subject of research [1,2] . In general, it is believed that artificial intelligence can be used for early diagnosis of diseases, which is one of the major concerns of people today [3] .  \nThis research is about using machine learning algorithms for early diagnosis of heart diseases that could cost many lives by 2050 [4] . For training machine learning algorithms, a dataset consisting of individuals who have already had heart disease in their medical  \nhistory and individuals who have never had heart problems before will be used. Data from more than 250,000 people will be used for the proposed research, and the accuracy of the results will be compared against the most popular machine learning algorithms. Corr function will be used to reduce data features in the dataset to save time and unit costs. Agile project development methods will be used during the project. Sprint planning and processes are dynamically managed to control the project process.  \nFig. 1.
