How aging affects heart immune cells and heart failure during infections

Official title: Role of Aging on cardiac macrophage dysfunction and heart failure during infection

Funded at Ohio State University · NIH-10620781 · Data updated 2026-11-12

This study looks at how getting older affects the immune cells in the heart, especially during infections, to help us understand why older adults are more at risk for heart problems and find better treatments for them.

Who could benefit from this research

Could help

Ideal candidates for this research are elderly individuals, particularly those with a history of cardiac issues or infections.

Less likely to help

Patients who are younger or do not have any cardiovascular conditions or infections may not benefit from this research.

What this research studies

This research investigates how aging impacts the function of immune cells in the heart, particularly during infections. It focuses on the elderly population, who are more vulnerable to cardiac infections due to chronic inflammation, a phenomenon known as 'inflamm-aging.' The study aims to understand the changes in heart immune cells during infections and how these changes contribute to heart failure. By examining the mechanisms behind these processes, the research seeks to identify potential therapeutic strategies for elderly patients suffering from cardiac infections.

Why it matters

Potential benefit: If successful, this research could lead to improved treatment options for elderly patients with heart infections, potentially reducing the risk of heart failure and death.

How similar studies have gone: Other research has shown promising results in understanding immune responses in aging, but this specific approach to cardiac infections in the elderly is relatively novel.
