Burden of valvular heart diseases: a population-based study

Area of Science:

• Cardiology
• Public Health
• Epidemiology

Background:

• Valvular heart diseases are often underestimated as a public health concern.
• This study investigates the prevalence and survival impact of valvular heart diseases in the general population.

Purpose of the Study:

• To determine the prevalence of valvular heart diseases in the general population.
• To assess the effect of valvular heart diseases on overall survival.

Main Methods:

• Pooled data from population-based studies involving 11,911 randomly selected adults assessed via echocardiography.
• Analyzed data from a community study of 16,501 adults assessed by clinically indicated echocardiography.

Main Results:

• Moderate or severe valve disease found in 615 adults (2.5% national prevalence) in the general population, increasing with age.
• In the community, 1.8% of adults had valve disease, also increasing with age.
• Valve disease was associated with increased mortality risk (1.36 in population, 1.75 in community).

Conclusions:

• Moderate or severe valvular diseases are prevalent, especially in older adults.
• Women in the community were diagnosed less often, potentially linked to lower survival.
• Valvular heart diseases constitute a significant public health problem.
