Gender differences in mortality among statin users aged 80 years or more

Area of Science:

• Gerontology
• Cardiology
• Pharmacology

Background:

• Prognosis of statin therapy in adults aged 80+ is poorly understood.
• Gender differences in statin therapy outcomes for the very elderly are unclear.

Purpose of the Study:

• To investigate the association between statin therapy and mortality.
• To examine gender differences in statin therapy's impact on survival in individuals aged 80 years and older.

Main Methods:

• Historical prospective study at a tertiary medical center.
• Review of medical charts for patients aged ≥80 years admitted over one year.
• Analysis of all-cause 3-year mortality and survival rates based on statin use.

Main Results:

• Statin use was associated with significantly lower 3-year mortality in women (24.2% vs. 57.1%).
• Women using statins showed significantly higher 3-year survival rates for cardiovascular prevention.
• Statin therapy was independently linked to reduced 3-year mortality in women (HR=0.3).

Conclusions:

• Statin therapy is linked to improved 3-year survival exclusively in women aged 80 and above.
• Findings suggest a gender-specific benefit of statins in the very elderly population.
