Abstract : Cardiovascular diseases are among the leading causes of mortality globally, with heart attacks (myocardial infarctions) significantly contributing to the alarming statistic. In Malaysia, a concerning trend has emerged: there is an increasing incidence of heart attack fatalities among individuals under the age of 60, highlighting a critical health issue that warrants immediate attention. The study specifically focuses on the age distribution of heart attack fatalities, carefully examining the risk factors that disproportionately impact younger populations. The approach included eligibility criteria, study selection, data extraction, and synthesis phases, ensuring robust findings. Key aspects included strict inclusion of relevant studies, a comprehensive search across academic databases, and a structured data extraction process, culminating in qualitative synthesis to identify lifestyle-related risk factors and healthcare disparities. Findings suggest that lifestyle-related factors, combined with delayed health-seeking behaviors and geographic disparities in healthcare access, play a significant role in the rising fatalities within the demographic. The discussion underscores the urgent need for targeted public health interventions to address these modifiable risk factors effectively. Additionally, it advocates for enhancements in diagnostic tools and the implementation of early intervention programs designed to improve health outcomes for at-risk individuals. The study emphasizes the immediate necessity for comprehensive strategies aimed at lowering heart attack mortality rates, particularly among younger populations, through a multifaceted approach that includes prevention, education, and improved healthcare access. Future research should focus on evaluating the long-term effectiveness of these targeted interventions and exploring the potential of emerging technologies in the early detection. Patient or Public Contribution: Patient and Public Involvement and Engagement (PPIE) was not applicable to the study, as it is a systematic review relying exclusively on existing literature and secondary data sources. The research did not entail any direct involvement of individuals, nor did it include surveys, interviews, or the gathering of personal information. Given that no human participants were included, there was no need for formal informed consent. The study is based solely on publicly accessible data and findings from previously published work. Consequently, ethical approval or participant consent was not required for conducting the research.
