摘要
ObjectiveCardiomyopathy (CM) at delivery is increasing in prevalance. The objective of this study was to determine which medical conditions are attributable to this increasing prevalance. DesignPopulation prevalence study from 2000 to 2009. SettingThe Nationwide Inpatient Sample (NIS). SamplePregnant women admitted for delivery were identified in the NIS for the years 2000-2009. MethodsTemporal trends in pre-existing medical conditions and in medical and obstetric complications at delivery admissions were determined by linear regression. The change in the prevalence of CM among all pregnant women was compared with the change in the prevalance of CM among pregnant women without pre-existing conditions or complications. Main outcome measurePrevalence of CM. ResultsThe prevalence of CM increased from 0.25 per 1000 deliveries in 2000 to 0.43 per 1000 deliveries in 2009 (P<0.0001). Women with chronic hypertension had increased odds of developing CM compared with women without chronic hypertension (odds ratio, OR, 13.2; 95% confidence interval, 95%CI, 12.5-13.7). The linear increase in chronic hypertension over the 10-year period was the single identified pre-existing medical condition that explained the increasing prevalence of CM at delivery (P=0.005 for the differences in slopes for linear trends). ConclusionsPregnant women with chronic hypertenion are at an increased risk for CM at delivery, and the increasing prevalence of chronic hypertension is an important factor associated with the increasing prevalence of CM at the time of delivery. Among women without chronic hypertension, the prevalence of CM at delivery did not change during the time period.
