Plasma Lipid Analysis of Simultaneous Application of Radiofrequency Synchronized With HIFEM for Fat Reduction in Same-Day Multiple Sessions

Abstract

BACKGROUND High-intensity focused electromagnetic field (HIFEM) and synchronized radiofrequency (RF) technologies have been shown to be safe and effective on multiple body parts OBJECTIVE To determine the plasma lipid levels and liver function tests of consecutive HIFEM + RF procedures delivered on the same day. METHODS Eight women and 2 men (24–59 years, BMI 22.4–30.6 kg/m2) 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. RESULTS 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. CONCLUSION Plasma levels remained stable and normal or lipids and LFTs for multiple same-day treatments of RF plus HIFEM.
