Sex differences in age-related cardiovascular mortality

Area of Science:

• Cardiology
• Public Health
• Epidemiology

Background:

• Sex-based physiological differences influence disease presentation and risk.
• Conflicting data exist regarding mid-life cardiovascular disease (CVD) risk in women.
• This study investigates sex differences in age-adjusted mortality for CVD and non-vascular diseases.

Purpose of the Study:

• To analyze sex-specific mortality rates for cardiovascular disease (CVD) and non-vascular diseases.
• To examine age-related trends in CVD mortality for men and women.
• To identify critical age groups for CVD risk in each sex.

Main Methods:

• Analysis of over one million deaths from the Finnish Causes of Death Register (1986-2009).
• Stratification of mortality data by sex and 5-year age categories.
• Calculation of age-standardized annual mortality rates per 100,000 population.

Main Results:

• Age-standardized CVD mortality was 80% higher in men (442/100,000) than in women (246/100,000).
• Male CVD mortality increased in parallel with non-vascular mortality after age 45-54.
• Female CVD mortality rose significantly faster than non-vascular mortality from age 60 onwards.

Conclusions:

• Cardiovascular disease (CVD) mortality accelerates in men at younger ages.
• Women show a pronounced increase in CVD mortality risk around age 60.
• Urgent need to identify and prevent CVD risk factors in mid-life women.
