Abstract
Heart failure (HF) is a growing public health concern, with an increasing incidence among younger populations. Traditionally, HF was considered a condition primarily affecting the elderly, but of late, emerging evidence hints at a rapidly rising HF incidence in youth in the past 2 decades. HF in youth has been linked to a complex interaction between emerging risk factors, such as metabolic syndrome, environmental exposures, genetic predispositions, and lifestyle behaviors. This review examines these evolving determinants, including substance abuse, autoimmune diseases, and the long-term cardiovascular effects of coronavirus disease 2019, which disproportionately affect younger individuals. Through a comprehensive analysis, the study highlights the importance of early detection, targeted prevention strategies, and multidisciplinary management approaches to address this alarming trend. Promoting awareness and integrating age-specific interventions could significantly reduce the burden of HF and improve long-term outcomes among younger populations.
