BACKGROUND
The relationship between patterns of outpatient oral loop diuretic (LD) dose reduction and prognosis in patients with heart failure (HF) remains unclear.
METHODS
We evaluated 679 patients with HF-prescribed LDs at baseline between September 2015 and August 2019. Dose reduction was defined as a change to a lower LD dose than the previous outpatient dose. Dose intensification was defined as a change to a higher LD dose than the previous outpatient dose. Patients were classified into no-reduction (no LD dose reduction during follow-up) and reduction groups (categorized into successive-reduction [≥2 successive LD dose reductions without intervening LD dose intensification] and single-reduction [LD dose reduction without successive dose reduction] groups). The primary outcomes were all-cause death, HF hospitalization (HFH), and the composite of cardiovascular death (CVD) or HFH.
RESULTS
Within a median follow-up of 53.7 (range, 2.6-99.1) months, 156 deaths were recorded: 121 (29 %), 31 (15 %), and three (4 %) patients in the no-reduction (n = 411), single-reduction (n = 195), and successive-reduction (n = 73) groups, respectively. After adjusting for cofounders, the reduction group had a lower risk of primary outcomes than the no reduction group (all-cause death: hazard ratio (HR) = 0.65, 95 % confidence interval (CI) = 0.44-0.96; CVD or HFH: HR=0.69, 95 %CI=0.52-0.93; HFH: HR=0.69, 95 % CI=0.52-0.93). The successive-reduction group had a lower risk of the composite of CVD or HFH (HR=0.26, 95 % CI: 0.10-0.67) and HFH (HR=0.34, 95 % CI=0.13-0.86) than the single-reduction group.
CONCLUSIONS
Outpatient LD dose reduction patterns can be indicators of good prognosis in HF patients.
背景
门诊口服袢利尿剂（LD）剂量减少模式与心力衰竭（HF）患者预后之间的关系尚不清楚。
方法
我们评估了2015年9月至2019年8月期间679例基线时接受LD治疗的HF患者。剂量减少定义为改为低于先前门诊剂量的LD剂量。剂量增加定义为改为高于先前门诊剂量的LD剂量。患者分为未减少组（随访期间未进行LD剂量减少）和减少组（分为连续减少组[≥2次连续LD剂量减少且无中间LD剂量增加]和单次减少组[LD剂量减少但无连续剂量减少]）。主要结局为全因死亡、HF住院（HFH）以及心血管死亡（CVD）或HFH的复合结局。
结果
在中位随访53.7（范围2.6 - 99.1）个月期间，记录了156例死亡：未减少组（n = 411）中有121例（29%）、单次减少组（n = 195）中有31例（15%）、连续减少组（n = 73）中有3例（4%）。在对混杂因素进行校正后，减少组的主要结局风险低于未减少组（全因死亡：风险比（HR）= 0.65，95%置信区间（CI）= 0.44 - 0.96；CVD或HFH：HR = 0.69，95%CI = 0.52 - 0.93；HFH：HR = 0.69，95%CI = 0.52 - 0.93）。连续减少组的CVD或HFH复合结局（HR = 0.26，95%CI：0.10 - 0.67）和HFH（HR = 0.34，95%CI = 0.13 - 0.86）风险低于单次减少组。
结论
门诊LD剂量减少模式可作为HF患者预后良好的指标。
