Multimorbidity of cardiovascular disease subtypes in a prospective cohort of 1.2 million UK women.

Objective: Cardiovascular multimorbidity (CVM) is the co-occurrence of multiple cardiovascular disease subtypes (CVDs) in one person. Because common patterns and incidence of CVM are not well-described, particularly in women, we conducted a descriptive study of CVM in the Million Women Study, a large population-based cohort of women.

Methods: UK women aged 50-64 years were followed up using hospital admissions and mortality records for an average of 19 years.
