Low-level laser therapy improves the inflammatory profile of rats with heart failure

Following heart failure (HF), immune activation leads to an imbalance between pro-inflammatory and anti-inflammatory cytokines. Low-level laser therapy (LLLT) has been used as an anti-inflammatory treatment in several disease conditions. However, the effect of LLLT on the skeletal muscle of rats wit...

description Following heart failure (HF), immune activation leads to an imbalance between pro-inflammatory and anti-inflammatory cytokines. Low-level laser therapy (LLLT) has been used as an anti-inflammatory treatment in several disease conditions. However, the effect of LLLT on the skeletal muscle of rats with HF remains unclear. The present report aimed to evaluate the influence of LLLT on the inflammatory profile of rats with HF. The left coronary artery was ligated to induce HF and a sham operation was performed in the control groups. Male Wistar rats ( n  = 49) were assigned to one of six groups: placebo sham rats (P-Sham; n  = 8), LLLT at a dose of 3 J/cm 2 sham rats (3 J/cm 2 -Sham; n  = 8), LLLT at a dose of 21 J/cm 2 sham rats (21 J/cm 2 -Sham; n  = 8), placebo HF rats (P-HF; n  = 9), LLLT at a dose of 3 J/cm 2 HF rats (3 J/cm 2 -HF; n  = 8), and LLLT at a dose of 21 J/cm 2 HF rats (21 J/cm 2 -HF; n  = 8). Four weeks after myocardial infarction or sham surgery, rats were subjected to LLLT (InGaAlP 660 nm, spot size 0.035 cm 2 , output power 20 mW, power density 0.571 W/cm 2 , energy density 3 or 21 J/cm 2 , exposure time 5.25 s and 36.75 s) on the right gastrocnemius for 10 consecutive days.
