Temporal Prognostic Factors in Elderly Patients with Acute Heart Failure: A Cohort Study from a Spanish Emergency Department.

Some variables showed a trend toward association without reaching statistical significance, such as previous AHF episodes (OR 1.58; 95% CI 0.85–2.95; p = 0.15), respiratory rate >30 bpm (OR 2.08; 95% CI 0.65–6.61; p = 0.22), or hospital admission (OR 2.10; 95% CI 0.93–4.78; p = 0.08).

Similarly, symptoms such as lower limb edema (OR 1.04; 95% CI 0.57–1.88; p = 0.91) or pulmonary crackles (OR 0.96; 95% CI 0.53–1.74; p = 0.88) did not reach statistical significance, nor did other potential PFs of the AHF episode, such as therapeutic non-adherence (not estimable) or hypertensive crisis (OR 0.54; 95% CI 0.07–4.15; p = 0.55). 3.3.2.

Regarding NYHA functional classes, in addition to class IV, class III (OR 2.88; 95% CI 1.68–4.97; p < 0.01) reached statistical significance in long-term prediction, while class II (OR 1.70; 95% CI 1.01–2.88; p = 0.05) showed a trend toward significance without fully reaching it.
