title: Normal left ventricular ejection fraction in older persons with congestive heart failure.
abstract: OBJECTIVE
  To investigate in older patients with congestive heart failure (CHF) associated with prior myocardial infarction or hypertension the relationship between normal left ventricular (LV) ejection fraction and age, gender, hypertension, prior myocardial infarction, and atrial fibrillation.
  
  
  METHODS
  A prospective study was performed in 572 older patients (age >60 years) with CHF associated with prior myocardial infarction or hypertension and technically adequate two-dimensional echocardiograms for measuring LV ejection fraction.
  
  
  METHODS
  A long-term health-care facility.
  
  
  METHODS
  One hundred seventy-seven men and 395 women, mean age 82+/-8 years, with CHF associated with prior myocardial infarction or hypertension.
  
  
  RESULTS
  Normal LV ejection fraction (> or = 50%) occurred in 66 of 177 men (37%) and in 221 of 395 women (56%) (p<0.0001). Multiple logistic regression analysis showed that independent risk factors for normal LV ejection fraction in patients with CHF were no prior myocardial infarction (p=0.0001; odds ratio=3.048), female gender (p=0.0004; odds ratio=1.978), and age (p=0.016; odds ratio=1.029).
  
  
  CONCLUSIONS
  Normal LV ejection fraction occurred in 50% of 572 older patients with CHF associated with prior myocardial infarction or hypertension. Independent risk factors for normal LV ejection fraction in patients with CHF were no prior myocardial infarction, female gender, and age.
