Which population is HFrEF more commonly found in?

Heart failure with reduced ejection fraction (HFrEF) is increasingly prevalent among older adults due to a variety of age-related factors, including the higher likelihood of developing conditions such as coronary artery disease, hypertension, and diabetes. As individuals age, the heart undergoes both structural and functional changes, making the older population more susceptible to heart failure.

The deterioration of the heart's ability to pump effectively, resulting in a reduced ejection fraction, is often seen in conjunction with other age-related comorbidities. Moreover, the prevalence of HFrEF is strongly associated with the aging process and its related decline in cardiovascular health, making older adults the primary group where this condition is found.

In contrast, young athletes, pregnant women, and children typically have healthier cardiac function and are less likely to exhibit the kind of heart dysfunction seen in HFrEF. Therefore, older adults represent the population where HFrEF is more commonly found, aligning with the understanding of cardiovascular health trends in aging.
