Key result
Overt dilated cardiomyopathy point prevalence reaches ~8 per 100,000 in England, with marked regional variation.
Why the study?
The prevalence of overt dilated cardiomyopathy in two regions of England was not well defined.
Cross-Sectional (n=913,836)
Yes
Survey-based prevalence estimates warrant cautious interpretation; leaves open true epidemiology and natural history of dilated cardiomyopathy.
The prevalence of dilated cardiomyopathy was assessed in two regions in England from 420 replies to 771 questionnaires sent to general practitioners. Overall point prevalence was 8.317 per 100 000 population in areas covering a total sample of 913 836 inhabitants. There was a statistically significant regional variation between East Anglia (Norfolk, Suffolk, and Cambridgeshire) and Essex, Hertfordshire, and Bedfordshire. Though the natural history of dilated cardiomyopathy remains to be defined, this study has provided an assessment of point prevalence of overt cases of this condition.

E. G. J. Olsen (1985) conducted a cross-sectional in Dilated cardiomyopathy (n=913,836). Geographic region was evaluated on Point prevalence of dilated cardiomyopathy. The overall point prevalence of overt dilated cardiomyopathy was 8.317 per 100,000 population across a sample of 913,836 inhabitants in England, with significant regional variation observed.
