Prevalence and Incidence of Mitral-valve prolapse
Prevalance of Mitral-valve prolapse:
2% of the adult population (NHLBI estimate) ... see also overview of Mitral-valve prolapse.
approx 1 in 50 or 2.00% or 5.4 million people in USA [Source statistic for calcuation: "2% of the adult population (NHLBI estimate)" -- see also general information about data sources]
Mitral-valve prolapse: Rare Disease
Mitral-valve prolapse is listed as a "rare disease" by the Office of
Rare Diseases (ORD) of the National Institutes of Health
(NIH). This means that Mitral-valve prolapse, or a subtype of Mitral-valve prolapse,
affects less than 200,000 people in the US population.
About prevalence and incidence statistics:
The term 'prevalence' of Mitral-valve prolapse usually refers to the estimated population
of people who are managing Mitral-valve prolapse at any given time.
The term 'incidence' of Mitral-valve prolapse refers to the annual diagnosis rate,
or the number of new cases of Mitral-valve prolapse diagnosed each year.
Hence, these two statistics types can differ:
a short-lived disease like flu can have high annual incidence but low prevalence,
but a life-long disease like diabetes has a low annual incidence but high prevalence.
