[Congestive heart failure with intact systolic function].
A retrospective study was undertaken of the cases of patients admitted for congestive cardiac failure over a 4 year period, and investigated by radionuclide angiography to determine the prevalence of cardiac failure with normal left ventricular systolic function, to document the underlying mechanisms of this condition and to assess whether the clinical data could predict the presence or absence of left ventricular systolic dysfunction. After excluding patients with significant valvular disease, severe renal failure, or myocardial infarction in the previous 2 months, the study population comprised 152 patients divided into 2 groups: Group I (N = 112) with abnormal systolic function (radionuclide ejection fraction less than 45%) and Group II (N = 40) with normal systolic function (radionuclide ejection fraction greater than or equal to 45%). The clinical, echocardiographic and radionuclide angiographic data was analysed (global ejection fraction in both groups and peak filling rate in Group II). The patients in Group II (26% of the total study population) were older (66.5 +/- 12.4 vs 61.3 +/- 12.3 years, p less than or equal to 0.02), were more often female (35% vs 17.9%, p less than or equal to 0.02), had acute cardiac failure (75% vs 37%, p less than 0.00001), and were frequently hypertensive (65% vs 39%, p less than or equal to 0.005). Univariate analysis of clinical and radiological signs did not show any significant difference between the two groups except for increased jugular venous pressure and cardiomegaly which were more common in Group I (56% vs 25%, p less than 0.00001 and 93% vs 68%, p less than or equal to 0.00001, respectively).(ABSTRACT TRUNCATED AT 250 WORDS)
