Effectiveness of Trimetazidine in Patients with Stable Angina Pectoris of Various Durations: Results from ODA.

ABSTRACT:

Introduction

Trimetazidine (TMZ) is an antianginal agent that acts directly at the myocardial cell level and which is now available in a once-daily (od) formulation.

Methods

ODA, a 3-month, observational, multicenter study in Russia, assessed the effectiveness and tolerability of TMZ 80 mg od in patients with stable angina and persisting symptoms, in real-life settings. The present analysis explored the effects of adding TMZ to background antianginal treatment with respect to the duration of stable angina.

Results

A total of 3032 patients were divided into four groups according to stable angina pectoris duration since diagnosis, ranging from less than 1 year to more than 10 years. A decrease in frequency of angina attacks was observed, including in patients with angina duration < 1 year, in whom the frequency of weekly angina attacks decreased from 3.8 ± 2.9 to 1.4 ± 1.7 at 1 month and 0.6 ± 1.0 at 3 months. Short-acting nitrate consumption and proportion of angina-free patients decreased, and self-reported physical activity and adherence to antianginal therapy improved in all patient groups, including recently diagnosed patients and starting already at month 1.

Conclusions

Addition of TMZ 80 mg od to antianginal treatment was effective in reducing the frequency of angina attacks and the use of short-acting nitrates, improving Canadian Cardiovascular Society (CCS) class, self-reported physical activity, and adherence to antianginal therapy. These beneficial effects were observed in patient groups with different durations of stable angina, suggesting an opportunity for decreasing angina burden even in recently diagnosed patients.

Project description:IntroductionTrimetazidine (TMZ) has been shown to be efficacious for angina treatment. The TMZ 80-mg formulation allows one-daily (od) dosage, which could improve symptom control and adherence.MethodsThe 3-month, observational, multicenter, prospective ODA (antianginal effectiveness and tolerability of trimetazidine modified release 80 mg Once Daily in stable Angina patients in real-world practice) study assessed TMZ 80 mg od effectiveness in stable angina patients with persistent symptoms despite therapy. Two clinical situations were compared: patients who initiated treatment with TMZ 80 mg od (initiation group) and patients who were previously treated with TMZ 20 mg thrice daily (tid) or TMZ 35 mg MR twice daily (bid) and switched to TMZ 80 mg od (switch group). Number of angina attacks, short-acting nitrate (SAN) consumption, self-reported patient daily activity, Canadian Cardiovascular Society (CCS) class, adherence to antianginal therapy, overall efficacy and tolerability were assessed.ResultsA significant decrease in weekly number of angina attacks was observed for both the initiation group (n = 1841 patients) from 4.8 ± 3.5 at baseline to 0.9 ± 1.4 at 3 months (M3) (P < 0.001), and the switch group (n = 1216 patients) from 4.4 ± 1.3 at baseline to 0.9 ± 1.3 at M3 (P < 0.001). Significant reduction in SAN consumption and improvement in CCS class were observed for both groups. Adherence to antianginal therapy improved in both groups at 1 month (M1) and M3. Overall effectiveness of TMZ 80 mg od was rated by physicians as "very good" (68% initiation group, 70% switch group), "good" (31% initiation group, 29% switch group), "moderate" (1%, both groups) or "poor" (< 1%, both groups). Overall tolerability of TMZ 80 mg od was rated by physicians as "very good" (75%), "good" (25%) or "moderate" (< 1%) in both groups.ConclusionsTMZ 80 mg od, in association with other antianginal therapy, effectively reduced angina attacks and SAN consumption and improved physical activity and adherence to antianginal therapy both in patients initiating TMZ treatment and those switching from a bid or tid formulation.Trial registrationISRCTN registry Identifier, ISRCTN97780949.FundingServier.

Project description:IntroductionPrevious reviews indicate that the effect of acupuncture on stable angina pectoris (SAP) remains controversial. The results of trials published in the past 5 years may possibly change this situation, but an updated systematic review is not available. We therefore designed this study to systematically assess the efficacy and safety of acupuncture for treating SAP.Methods and analysisNine online databases will be searched without language or publication status restrictions from their inception to September 2017. Randomised controlled trials that include patients with stable angina receiving acupuncture therapy versus a control group will be deemed eligible. The selection of studies, data extraction and risk of bias assessment will be carried out by two independent reviewers. Data synthesis will be performed using RevMan V.5.3 software with either a fixed effects model or random effects model, depending on the heterogeneity test. Evidence quality will be evaluated using the Grading of Recommendations Assessment, Development and Evaluation system. The efficacy-effectiveness spectrum for each included trial will be rated using the Rating of Included Trials on the Efficacy-effectiveness Spectrum tool. Outcomes of interest include the improvement of weekly angina attacks and reduction of nitroglycerin medication use after receiving acupuncture treatment, the incidence of cardiovascular events, heart rate variability, pain intensity measured on a visual analogue scale, total workload and exercise duration at peak exercise, safety and adverse events. A meta-analysis will be conducted if no considerable heterogeneity is detected. The results will be presented as risk ratios with 95% CIs for dichotomous data and weighted mean differences or standardised mean differences with 95% CIs for continuous data.Ethics and disseminationThis systematic review will not involve private information from individuals or endanger their rights, and therefore does not necessarily require ethical approval. The results may be published in a peer-reviewed journal or disseminated in relevant conferences.Trial registration numberCRD42015016201.
