Abstract Funding Acknowledgements Type of funding sources: Public grant(s) – National budget only. Main funding source(s): Indonesia"s Ministry of Research and Technology grants Background Inflammation, oxidative stress and lipid peroxidation activities contribute to the progression of atherosclerosis leading to myocardial infarction (MI). These sustainable cascade are considered to remain, in fact after the episode of MI. Polysaccharide peptide is renowned to exert anti-oxidative and lipid-lowering effects, thus may impair subsequent post-infarction plaque accumulation. Purpose To evaluate the role of polysaccharide peptide of Ganoderma lucidum mycelium extracts (β-1,3/1,6-D-Glucan) as potent protective antioxidant and lipid-lowering agent in post MI patients. Methods This was a prospective, double-blind, placebo-controlled, randomised clinical trial in 45 post MI patients who had undergone reperfusion or conservative therapy. The eligible and consenting patients were randomly assigned (1:1 ratio) into two groups i.e. treated group (TG) and control group (CG). Treated group was given 180 mg β-1,3/1,6-D-Glucan thrice a day for 90 days, and control group received placebo. Variables measured were nitric oxide (NO), superoxide dismutase (SOD), malondialdehyde (MDA), plasma total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides. All measurements were conducted at baseline and after 90-days. All patients received guideline-driven therapy throughout the study. Results There was no significant difference in the baseline characteristics between the two groups (all p > 0.05). At 90 days, allocation to polysaccharide peptide demonstrated significant increase in NO and SOD (p = 0.020, p = 0.023; respectively) and also significant reduction in MDA (p = 0.001) as compared to placebo. Treated group compared with placebo revealed significant reduction in LDL-C (p = 0.036), but not in total cholesterol, HDL-C and triglycerides (p = 0.105, p = 0.398, p = 0.843; respectively). Conclusions Polysaccharide peptide exhibits potent protective anti-oxidative and lipid-lowering properties in post MI patients. It may offer benefit on top of standard medical treatment.
