We were looking for the threshold values of the chronic CD4+ T cell preserved fraction T*/T0 and set point viral load that best reproduced the division into progressors and controllers based on survival longer than 600 days.
The high correlation (mostly above 0.9) indicates the highly preserved fraction of microRNA in paraffin blocks even after many years.
Because heart failure (HF) with reduced ejection fraction (HFrEF) and preserved ejection fraction (HFpEF) are different clinical entities with differing demographic characteristics, common HF outcomes may occur at different rates.
Furthermore, patients with either a reduced ejection fraction (HFrEF) or preserved ejection fraction (HFpEF) were also included.
Patients older >50 years, with New York Heart Association (NYHA) stage I, II or III CHF with reduced ejection fraction (HFrEF) or preserved ejection fraction (HFpEF) are eligible for inclusion.
Reduced LV ejection fraction was present in 64 and preserved ejection fraction in 70 cases.
A LV ejection fraction of ≥ 50%% was regarded as preserved ejection fraction [ 19].
Moreover, echocardiography is needed to differentiate HF with a preserved ejection fraction (HFpEF) from HF with a reduced ejection fraction (HFrEF) [ 1].
The relative prevalence of HF with reduced ejection fraction [left ventricular systolic dysfunction (LVSD) or HFrEF] and preserved ejection fraction (HFpEF) is unknown, though HFpEF may account for >50% of HF hospitalizations in the elderly.
Another study evaluating the impact of treating anemia in subjects with preserved ejection fraction (HFPEF, Anemia in Heart Failure With a Preserved Ejection Fraction study) on functional capacity, ventricular structure and function, along with overall functional status is under way.
In classical spectrum leasing as discussed in [22, 30], MUE preserves a fraction β(0<β≤1) of its superframe for the secret communication and leaves the remaining fraction 1−β of the superframe for jammer's transmission.
