Efficacy of AI-Guided (GenAISTM) Dietary Supplement Prescriptions versus Traditional Methods for Lowering LDL Cholesterol: A Randomized Parallel-Group Pilot Study.

Emerging evidence suggests that personalized dietary supplement regimens can significantly influence lipid metabolism and cardiovascular risk. The efficacy of AI-guided dietary supplement prescriptions, compared with standard physician-guided prescriptions, remains underexplored. In a randomized, parallel-group pilot study, 70 patients aged 40-75 years with LDL-C levels between 70 and 190 mg/dL were enrolled. Participants were randomized to receive either AI-guided dietary supplement prescriptions or standard physician-guided prescriptions for 90 days. The primary endpoint was the percent change in LDL-C levels. Secondary endpoints included changes in total cholesterol, HDL-C, triglycerides, and hsCRP. Supplement adherence and side effects were monitored. Sixty-seven participants completed the study. The AI-guided group experienced a 25.3% reduction in LDL-C levels (95% CI: -28.7% to -21.9%), significantly greater than the 15.2% reduction in the physician-guided group (95% CI: -18.5% to -11.9%; p < 0.01). Total cholesterol decreased by 15.4% (95% CI: -19.1% to -11.7%) in the AI-guided group compared with 8.1% (95% CI: -11.5% to -4.7%) in the physician-guided group (p < 0.05). Triglycerides were reduced by 22.1% (95% CI: -27.2% to -17.0%) in the AI-guided group versus 12.3% (95% CI: -16.7% to -7.9%) in the physician-guided group (p < 0.01). HDL-C and hsCRP changes were not significantly different between groups. The AI-guided group received a broader variety of supplements, including plant sterols, omega-3 fatty acids, red yeast rice, coenzyme Q10, niacin, and fiber supplements. Side effects were minimal and comparable between groups. AI-guided dietary supplement prescriptions significantly reduce LDL-C and triglycerides more effectively than standard physician-guided prescriptions, highlighting the potential for AI-driven personalization in managing hypercholesterolemia.

Effect of Methylfolate, Pyridoxal-5'-Phosphate, and Methylcobalamin (SolowaysTM) Supplementation on Homocysteine and Low-Density Lipoprotein Cholesterol Levels in Patients with Methylenetetrahydrofolate Reductase, Methionine Synthase, and Methionine Synthase Reductase Polymorphisms: A Randomized Controlled Trial.

Exploring the link between genetic polymorphisms in folate metabolism genes (MTHFR, MTR, and MTRR) and cardiovascular disease (CVD), this study evaluates the effect of B vitamin supplements (methylfolate, pyridoxal-5'-phosphate, and methylcobalamin) on homocysteine and lipid levels, potentially guiding personalized CVD risk management. In a randomized, double-blind, placebo-controlled trial, 54 patients aged 40-75 with elevated homocysteine and moderate LDL-C levels were divided based on MTHFR, MTR, and MTRR genetic polymorphisms. Over six months, they received either a combination of methylfolate, P5P, and methylcobalamin, or a placebo. At the 6 months follow-up, the treatment group demonstrated a significant reduction in homocysteine levels by 30.0% (95% CI: -39.7% to -20.3%) and LDL-C by 7.5% (95% CI: -10.3% to -4.7%), compared to the placebo (p < 0.01 for all). In the subgroup analysis, Homozygous Minor Allele Carriers showed a more significant reduction in homocysteine levels (48.3%, 95% CI: -62.3% to -34.3%, p < 0.01) compared to mixed allele carriers (18.6%, 95% CI: -25.6% to -11.6%, p < 0.01), with a notable intergroup difference (29.7%, 95% CI: -50.7% to -8.7%, p < 0.01). LDL-C levels decreased by 11.8% in homozygous carriers (95% CI: -15.8% to -7.8%, p < 0.01) and 4.8% in mixed allele carriers (95% CI: -6.8% to -2.8%, p < 0.01), with a significant between-group difference (7.0%, 95% CI: -13.0% to -1.0%, p < 0.01). Methylfolate, P5P, and methylcobalamin supplementation tailored to genetic profiles effectively reduced homocysteine and LDL-C levels in patients with specific MTHFR, MTR, and MTRR polymorphisms, particularly with homozygous minor allele polymorphisms.

The Impact of Glucomannan, Inulin, and Psyllium Supplementation (SolowaysTM) on Weight Loss in Adults with FTO, LEP, LEPR, and MC4R Polymorphisms: A Randomized, Double-Blind, Placebo-Controlled Trial.

This study aimed to determine the impact of a fiber supplement on body weight and composition in individuals with obesity with specific genetic polymorphisms. It involved 112 adults with obesity, each with at least one minor allele in the FTO, LEP, LEPR, or MC4R polymorphism. Participants were randomized to receive either a fiber supplement (glucomannan, inulin, and psyllium) or a placebo for 180 days. The experimental group showed significant reductions in body weight (treatment difference: -4.9%; 95% CI: -6.9% to -2.9%; p < 0.01) and BMI (treatment difference: -1.4 kg/m2; 95% CI: -1.7 to -1.2; p < 0.01) compared to placebo. Further significant decreases in fat mass (treatment difference: -13.0%; 95% CI: -14.4 to -11.7; p < 0.01) and visceral fat rating (treatment difference: -1.3; 95% CI: -1.6 to -1.0; p < 0.01) were noted. Homozygous minor allele carriers experienced greater decreases in body weight (treatment difference: -3.2%; 95% CI: -4.9% to -1.6%; p < 0.01) and BMI (treatment difference: -1.2 kg/m2; 95% CI: -2.0 to -0.4; p < 0.01) compared to heterozygous allele carriers. These carriers also had a more significant reduction in fat mass (treatment difference: -9.8%; 95% CI: -10.6 to -9.1; p < 0.01) and visceral fat rating (treatment difference: -0.9; 95% CI: -1.3 to -0.5; p < 0.01). A high incidence of gastrointestinal events was reported in the experimental group (74.6%), unlike the placebo group, which reported no side effects. Dietary supplementation with glucomannan, inulin, and psyllium effectively promotes weight loss and improves body composition in individuals with obesity, particularly those with specific genetic polymorphisms.

Evaluating the Impact of Omega-3 Fatty Acid (SolowaysTM) Supplementation on Lipid Profiles in Adults with PPARG Polymorphisms: A Randomized, Double-Blind, Placebo-Controlled Trial.

Emerging evidence suggests that PPARG gene polymorphisms may influence lipid metabolism and cardiovascular risk, with omega-3 fatty acids proposed to modulate these effects. This study aims to assess the effects of fish oil supplementation on cardiovascular markers among adults with PPARG gene polymorphisms in a randomized, double-blind, placebo-controlled trial. A cohort of 102 patients with LDL-C 70-190 mg/dL was randomized to receive either 2000 mg of omega-3 fatty acids or a placebo daily for 90 days. In the omega-3 group with PPARG polymorphisms, LDL-C was reduced by 15.4% (95% CI: -19.8% to -11.0%), compared with a 2.6% decrease in the placebo group (95% CI: -4.1% to -1.1%; p < 0.01). In the omega-3 group without PPARG polymorphisms, LDL-C was reduced by 3.7% (95% CI: -6.9% to -0.6%), not significantly different from the placebo group's reduction of 2.9% (95% CI: -5.1% to -0.8%; p = 0.28). The reduction in LDL-C was notably 11.7% greater in those with PPARG polymorphisms than in those without (95% CI: -19.3% to -4.0%; p < 0.01). Triglycerides decreased by 21.3% in omega-3 recipients with PPARG polymorphisms (95% CI: -26.5% to -16.2%; p < 0.01), with no significant changes in HDL-C, total cholesterol, or hsCRP levels in any groups. Minor allele frequencies and baseline characteristics were comparable, ensuring a balanced genetic representation. Omega-3 fatty acids significantly reduce LDL-C and triglycerides in carriers of PPARG polymorphisms, underlining the potential for genetic-driven personalization of cardiovascular interventions.

Quality of Life after Surgical Ablation of Persistent Atrial Fibrillation: A Prospective Evaluation.

AIM: To compare the quality of life (QoL) of patients with persistent atrial fibrillation (AF) and ischaemic heart disease after modified mini-maze (MM) procedure or pulmonary vein isolation (PVI) using radiofrequency ablation (RFA) with patients in the control group (coronary artery bypass graft [CABG]) alone. METHODS: In this prospective randomised study, we included 95 patients with persistent AF and coronary heart disease who underwent open-heart surgery combined with intraoperative irrigated RFA (irrRFA). Patients were randomly assigned to three groups: CABG and PVI using irrRA (CABG+PVI, n=31), CABG and MM procedure using irrRA (CABG+MM, n=30), and isolated CABG (CABG alone, n=34). All patients received implantable loop recorders (ILRs). Patient QoL was assessed using the Short Form 36 (SF-36) preoperatively, and one and two years post-operatively. The study primary end point was freedom from AF one year after operation, measured by implantable loop recorders (ILRs); secondary endpoint included long-term clinical outcomes. RESULTS: No reoperations or hospital mortalities were recorded. Mean follow-up was 14.4±9.7 months. The percentages of patients free from AF determined by ILR were 80%, 86.2%, and 44.1% in the CABG+PVI, CABG+MM, and in the CABG alone groups, respectively. The QoL significantly improved in CABG+PVI and CABG+MM groups compared with CABG alone group in most domains. CONCLUSION: Effective elimination of AF during CABG surgery improves QoL in all physical health domains of the SF-36 and the role-emotional functioning domain. Thus, patients with concomitant AF and coronary heart disease may benefit from intraoperative radiofrequency ablation to prevent relapse of the arrhythmia.

Assessment of results of surgical treatment for persistent atrial fibrillation during coronary artery bypass grafting using implantable loop recorders.

OBJECTIVES: We report our experience with a modified mini-maze procedure and pulmonary vein isolation using radiofrequency energy for treating persistent atrial fibrillation during coronary artery bypass grafting (CABG). METHODS: Ninety-five patients with persistent atrial fibrillation and coronary heart disease underwent open heart surgery combined with intraoperative irrigated radiofrequency ablation. Patients were randomized into the following three groups: CABG and irrigated radiofrequency pulmonary vein isolation (CABG+PVI, n = 31); CABG and an irrigated radiofrequency modified mini-maze procedure (CABG+MM, n = 30); and isolated CABG (CABG alone, n = 34). All patients received implantable loop recorders. RESULTS: No reoperation and no hospital mortality were recorded. Mean follow-up was 14.4 ± 9.7 months. The implantable loop recorder-determined freedom from atrial fibrillation was 80% in the CABG+PVI group, 86.2% in the CABG+MM group and 44.1% in the CABG alone group. CONCLUSIONS: Patients with concomitant atrial fibrillation and coronary heart disease may benefit from intraoperative ablation to prevent relapse of arrhythmia.

Ablation of paroxysmal atrial fibrillation during coronary artery bypass grafting: 12 months' follow-up through implantable loop recorder.

OBJECTIVES: The study aimed to identify responders to atrial fibrillation (AF) ablation, through continuous subcutaneous monitoring in patients with paroxysmal atrial fibrillation (PAF), who underwent epicardial pulmonary vein isolation (PVI) concomitantly with coronary artery bypass grafting (CABG). METHODS: Seventy-two patients aged 61.6±4.7 years with PAF underwent epicardial PVI with bipolar radiofrequency during CABG. Conduction block was confirmed by pacing. At the end of the procedure, the implantable loop recorder (ILR) for continuous monitoring was implanted in all patients. Follow-up data were collected through the ILR telemetry. Patients with an AF burden (AF%)<0.5% were considered AF free (responders). Patients with AF%>0.5% were classified as non-responders. The AF episodes stored by the implanted device were visually inspected by the investigators to confirm the arrhythmia. The data were collected each month during 1-year follow-up. RESULTS: No procedure-related complications occurred either for ablation or for the monitoring device. At the first post-ablation follow-up (1 month) during the blanking period, 37 patients (51%) were AF free, that is, with AF%<0.5%. At the end of the blanking period (3rd follow-up), 44 (61%) patients were AF free. At 12 months' follow-up, 52 (72%) patients were AF free. Among 20 (28%) patients with AF recurrence, six (30%) patients were completely asymptomatic. There were no ischaemic strokes during the 1-year follow-up. CONCLUSION: Concomitant AF ablation during CABG is effective in the treatment of AF, as assessed through 1 year of continuous monitoring. Use of subcutaneous monitors is safe and accurate for AF detection, clinically relevant in identifying responders and non-responders and managing the medical therapies accordingly.
