Nonpharmacological treatment of patients with hypertrophic obstructive cardiomyopathy (HOCM) comprises surgical myectomy (SME), alcohol septal ablation (ASA), and dual-chamber (DDD) pacing. The aim of the study was to compare the long-term effect of DDD pacing and ASA in symptomatic HOCM patients.
We evaluated retrospective data from three cardiocenters; there were 24 patients treated with DDD pacing included and 52 treated with ASA followed for 101 ± 49 and 87 ± 23 months, respectively.
In the group treated with DDD pacing, the left ventricle outflow tract gradient (LVOTG) decreased from 82 ± 44 mmHg to 21 ± 21 mmHg, and NYHA class improved from 2.7 ± 0.5 to 2.1 ± 0.6 (both P < 0.001). In the ASA-treated group, a decline in LVOTG from 73 ± 38 mmHg to 24 ± 26 mmHg and reduction in NYHA class from 2.8 ± 0.5 to 1.7 ± 0.8 were observed (both P < 0.001). The LVOTG change was similar in both groups (P = 0.264), and symptoms were more affected by ASA (P = 0.001).
ASA and DDD pacing were similarly effective in reducing LVOTG. The symptoms improvement was more expressed in patients treated with ASA.
肥厚性梗阻性心肌病(HOCM)患者的非药物治疗包括外科心肌切除术(SME)、酒精室间隔消融术(ASA)和双腔(DDD)起搏。本研究的目的是比较DDD起搏和ASA对有症状的HOCM患者的长期疗效。
我们评估了来自三个心脏中心的回顾性数据;其中包括24例接受DDD起搏治疗的患者和52例接受ASA治疗的患者,分别随访了101±49个月和87±23个月。
在接受DDD起搏治疗的组中,左心室流出道压差(LVOTG)从82±44mmHg降至21±21mmHg,纽约心脏协会(NYHA)心功能分级从2.7±0.5改善至2.1±0.6(均P<0.001)。在接受ASA治疗的组中,观察到LVOTG从73±38mmHg降至24±26mmHg,NYHA心功能分级从2.8±0.5降至1.7±0.8(均P<0.001)。两组的LVOTG变化相似(P = 0.264),而ASA对症状的影响更大(P = 0.001)。
ASA和DDD起搏在降低LVOTG方面同样有效。接受ASA治疗的患者症状改善更为明显。
