High-intensity focused electromagnetic field (HIFEM) and synchronized radiofrequency (RF) technologies have been shown to be safe and effective on multiple body parts.
To determine the plasma lipid levels and liver function tests of consecutive HIFEM + RF procedures delivered on the same day.
Eight women and 2 men (24-59 years, BMI 22.4-30.6 kg/m 2 ) underwent 4 30-minute consecutive HIFEM + RF procedures. The treated area differed according to gender (females: abdomen and lateral and inner thighs; males: abdomen and front and back thighs). Liver function (aspartate aminotransferase [AST], alanine aminotransferase [ALT], gamma-glutamyltransferase [GGT], alkaline phosphatase [ALP]) and lipid profile (cholesterol, high-density lipoprotein [HDL], low-density lipoprotein [LDL], triglycerides [TG]) was monitored from blood samples drawn before the treatment, 1 hour, 24 to 48 hours, and 1 month after treatment. The subject's satisfaction, comfort, abdominal circumference, and digital photographs were also monitored.
All 10 patients completed planned treatments and follow-up blood draws. No significant fluctuation or notable deviation in the measured blood parameters was observed. The average values during the study were in a range of AST 15.7 to 16.7IU/L, ALT 11.9 to 13.4IU/L, GGT 11.6 to 13.8IU/L, and ALP 71.4 to 77.2IU/L, TG 1.0 mmol/L, HDL 1.7 mmol/L, LDL 3.0 mmol/L, and cholesterol 5.0 to 5.1 mmol/L corresponded to the normal ranges. Subjects reported high comfort during the treatment and satisfaction with their results. No adverse event occurred.
Plasma levels remained stable and normal or lipids and LFTs for multiple same-day treatments of RF plus HIFEM.
高强度聚焦电磁场（HIFEM）和同步射频（RF）技术已被证明对多个身体部位安全有效。
确定同一天连续进行HIFEM + RF治疗后的血浆脂质水平和肝功能测试结果。
8名女性和2名男性（年龄24 - 59岁，体重指数22.4 - 30.6kg/m²）连续接受了4次30分钟的HIFEM + RF治疗。治疗部位因性别而异（女性：腹部、大腿内外侧；男性：腹部、大腿前后侧）。在治疗前、治疗后1小时、24至48小时以及治疗后1个月采集血样，监测肝功能（天冬氨酸转氨酶[AST]、丙氨酸转氨酶[ALT]、γ-谷氨酰转移酶[GGT]、碱性磷酸酶[ALP]）和血脂谱（胆固醇、高密度脂蛋白[HDL]、低密度脂蛋白[LDL]、甘油三酯[TG]）。同时监测受试者的满意度、舒适度、腹围和数码照片。
所有10名患者均完成了计划的治疗和随访采血。未观察到所测血液参数有明显波动或显著偏差。研究期间的平均值范围为AST 15.7至16.7IU/L、ALT 11.9至13.4IU/L、GGT 11.6至13.8IU/L、ALP 71.4至77.2IU/L、TG 1.0mmol/L、HDL 1.7mmol/L、LDL 3.0mmol/L，胆固醇5.0至5.1mmol/L均在正常范围内。受试者报告治疗期间舒适度高且对结果满意。未发生不良事件。
对于同一天多次进行的RF加HIFEM治疗，血浆水平保持稳定，脂质和肝功能测试结果正常。
