Key result
Diastolic heart failure showed no significant difference in hospital stay, readmission, morbidity, or mortality compared to systolic heart failure over 5 years.
Why the study?
Does prognosis differ between diastolic and systolic heart failure in elderly Saudi patients?

Does prognosis differ between diastolic and systolic heart failure in elderly Saudi patients?
In elderly Saudi patients with heart failure, those with diastolic heart failure have similar long-term morbidity and mortality compared to those with systolic heart failure.

Comparable long-term outcomes in diastolic vs systolic HF; leaves open need for prospective validation in broader populations.
Data from 519 patients older than 65 years with congestive heart failure (CHF) were analyzed after 5 years of clinical follow-up. Two groups were included in the analysis: 321 patients with ejection fractions > or =50% (group with diastolic heart failure) and 198 patients with reduced ejection fraction <50% (group with systolic heart failure). Hypertension (81%) was the strongest predictor of congestive heart failure, followed by diabetes (46%) and coronary disease (33%). Diastolic heart failure was more predominant in elderly female (P=.007), hypertensive (P=.0001), and hypertrophic (P=.001) patients. Length of hospital stay, readmission rate, all-cause morbidity, and cumulative mortality were not statistically significant between both groups (P=.09).

Elshaer et al. (2009) conducted a cohort in Congestive heart failure (CHF) (n=519). Diastolic heart failure (ejection fraction ≥50%) vs. Systolic heart failure (ejection fraction <50%) was evaluated on Length of hospital stay, readmission rate, all-cause morbidity, and cumulative mortality (p=0.09). Diastolic heart failure showed no significant difference in hospital stay, readmission, morbidity, or mortality compared to systolic heart failure over 5 years.
