[Case-controlled study of the prognosis of cardiac insufficiency in treated XXXX @entity1 ].

@entity1 @entity712 @entity101
The aim of this study is to compare the long-term mortality of @entity101 ( @entity101 ) hospitalized with early @entity712 ( @entity712 ), and @entity101 control without @entity712 . The study is based on a population of 2,050 @entity101 consecutively hospitalized for the first time for high blood pressure, between oct. 1969 and nov. 1983. Among them, 115 presented with early @entity712 (symptoms for less than 3 months, the diagnosis being made mainly on interview data, physical exam, and radio); they were matched with Controls (C) belonging to the same @entity101 population, on the following criteria: same sex, same age (+/- 3 years), same date of entry (+/- 3 months), no @entity712 at entry, 94 Cases (CHF) could be matched: 64 @entity1 and 30 @entity1 (mean age: 50 +/- 11). A mortality survey was done in April 1985, with response rates of 96 p. 100 (CHF) and 98 p. 100 (C). The mean follow-up period was 11 years. At entry, CHF differed highly significantly form C in many ways, and mainly in higher systolic BP, more frequent ECG changes (LV voltage, J-ST-T changes), more severe fundus oculi changes. The survival rate was assessed by life-table method. As a whole, it was significantly reduced in CHF vs C (p/0.005); the 10-years survival rates were respectively 51% (CHF) and 71% (C). Case-control comparison was examined for both sexes, and after division by the median age (50 years): CHF survival was significantly reduced in @entity1 , and in subjects aged 50 and more (p/0.03); no significant difference was observed for @entity1 and before 50. CHF were dichotomized for each available item at entry, and lifetable comparison was compared in both issuing sub-groups; no significant difference was observed, but for the age, with a better survival in youngest subjects (p/0.01).(ABSTRACT TRUNCATED AT 250 WORDS)
