Failure More Common Than Systolic Form - Symptoms are the Same But
Treatments Could Vary For Ejection - Relaxation Fraction
July 20th 2006
Mayo Clinic researchers say that diastolic heart failure is increasing
and now accounts for more than half of heart failure cases. They
evaluated data from a 15 year period and discovered that this heart
failure, which is characterized by a preserved ejection fraction,
affects more than half of the total 5 million heart failure patients.
The percentage of these cases increase from 38 percent to 47 percent to
54 percent in three consecutive five-year periods. There were 4,596
heart failure patients in this study. Hypertension, atrial fibrillation
and diabetes can worsen this type of heart failure.
The other type of heart failure is systolic failure. The ratio has
changed because there are more diastolic heart failure patients, with no
change in the number of systolic heart failure cases. The mortality
rates for the two types of heart failure are about the same.
