This study assessed patient and physician perceptions of heart failure (HF) disease severity and treatment options.
The prognosis for ambulatory patients with advanced HF on medical therapy is uncertain, yet has important implications for decision making regarding transplantation and left ventricular assist device (LVAD) placement.
Ambulatory patients with advanced HF (New York Heart Association functional class III to IV, Interagency Registry for Mechanically Assisted Circulatory Support profiles 4 to 7) on optimized medical therapy were enrolled across 11 centers. At baseline, treating cardiologists rated patients for perceived risk for transplant, LVAD, or death in the upcoming year. Patients were also surveyed about their own perceptions of life expectancy and willingness to undergo various interventions.
At enrollment, physicians regarded 111 of 161 patients (69%) of the total cohort to be at high risk for transplant, LVAD, or death, whereas only 23 patients (14%) felt they were at high risk. After a mean follow-up of 13 months, 61 patients (38%) experienced an endpoint of 33 deaths (21%), 13 transplants (8%), and 15 LVAD implants (9%). There was poor discrimination between risk prediction among both patients and physicians. Among physician-identified high-risk patients, 77% described willingness to consider LVAD, but 63% indicated that they would decline 1 or more other simpler forms of life-sustaining therapy such as ventilation, dialysis, or a feeding tube.
Among patients with advanced HF, physicians identified most to be at high risk for transplantation, LVAD, or death, whereas few patients recognized themselves to be at high risk. Patients expressed inconsistent attitudes toward lifesaving treatments, possibly indicating poor understanding of these therapies. Educational interventions regarding disease severity and treatment options should be introduced prior to the need for advanced therapies such as intravenous inotropic therapy, transplantation, or LVAD.
本研究评估了患者和医生对心力衰竭(HF)疾病严重程度和治疗选择的看法。
接受药物治疗的门诊晚期 HF 患者的预后不确定,但这对决定是否进行移植和左心室辅助装置(LVAD)植入具有重要意义。
在 11 个中心招募了接受优化药物治疗的门诊晚期 HF 患者(纽约心脏协会功能分级 III 至 IV 级,机械循环支持机构间注册登记 4 至 7 级)。在基线时,治疗心脏病专家根据患者在未来一年内接受移植、LVAD 或死亡的风险对患者进行评估。患者还接受了关于自身预期寿命和接受各种干预措施意愿的调查。
在入组时,医生认为在总队列的 161 名患者中,有 111 名(69%)患者具有较高的移植、LVAD 或死亡风险,而只有 23 名(14%)患者认为自己处于高风险状态。在平均 13 个月的随访后,61 名(38%)患者经历了 33 例死亡(21%)、13 例移植(8%)和 15 例 LVAD 植入(9%)的终点事件。患者和医生的风险预测之间的区分度较差。在医生确定的高危患者中,77%表示愿意考虑 LVAD,但 63%表示他们将拒绝 1 种或多种其他更简单的维持生命治疗,如通气、透析或喂养管。
在晚期 HF 患者中,医生认为大多数患者有较高的移植、LVAD 或死亡风险,而很少有患者认为自己处于高风险状态。患者对救生治疗的态度不一致,这可能表明他们对这些治疗方法的理解较差。应在需要进行静脉内正性肌力治疗、移植或 LVAD 等先进治疗之前,引入关于疾病严重程度和治疗选择的教育干预措施。
