Focale: study of systolic and diastolic heart failure in a French elderly population.Int J Cardiol. 2008 Feb 29; 124(2):188-92.IJ
The epidemic of heart failure (HF) in France has not been fully investigated and data on both the systolic and diastolic forms are limited.
To determine the prevalence, aetiology and treatments of both forms in French patients over 65 with HF (NYHA grade II-IV).
Cross-sectional study of 446 patients with HF recruited by 273 randomly selected cardiologists in France, with echocardiography and ECG available for central reading.
Prevalence of diastolic (DHF) and systolic (SHF) HF using the left ventricular ejection fraction (LVEF).
DHF, with a mean LVEF of 57.6+/-8.0%, was reported for 245 (54.9%) patients and SHF, with a mean LVEF of 33.33+/-8.0% was reported for 201 (45.1%) patients. Men were more prone to suffer SHF than DHF whereas for women the reverse was true. As compared to SHF, DHF endsystolic and enddiastolic volumes were smaller, the thickness/radius ratio was greater, with a longer E-wave deceleration time and a shorter peak filling rate. Aetiology and treatments were similar in both types of HF, except for ACE inhibitors and aldosterone antagonists, which were more frequently prescribed in SHF.
This observational study provides further knowledge of SHF and DHF in outpatients.
