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.
通过向全科医生发送771份问卷并收到420份回复,对英格兰两个地区扩张型心肌病的患病率进行了评估。在涵盖913836名居民总样本的地区,总体时点患病率为每10万人8.317例。东安格利亚(诺福克、萨福克和剑桥郡)与埃塞克斯、赫特福德郡和贝德福德郡之间存在统计学上显著的地区差异。尽管扩张型心肌病的自然病史仍有待确定,但本研究已对该疾病显性病例的时点患病率进行了评估。
