What is a primary effect of aging on cardiac function?

Aging has a significant impact on cardiac function, and one of the primary effects is the increased prevalence of heart disease. As individuals grow older, various physiological changes occur in the cardiovascular system, including thickening of the heart muscle, decreased elasticity of blood vessels, and alterations in the conduction system. These changes can lead to conditions such as hypertension, coronary artery disease, heart failure, and arrhythmias, which are more commonly observed in older adults.

The aging process also often correlates with lifestyle factors and comorbidities like diabetes and a sedentary lifestyle, which further contribute to cardiovascular risks. Thus, the increased prevalence of heart disease is a well-documented effect of aging on cardiac function. Understanding the implications of these changes is crucial for managing the health of older adults and developing appropriate interventions to mitigate risks associated with heart disease.
