Patients aged 80 years or older with non-ST-elevation myocardial infarction or unstable angina pectoris randomised to an invasive versus conservative strategy: angiographic and procedural results from the After Eighty study.

ABSTRACT: OBJECTIVES:We aimed to report the angiographic and procedural results of the After Eighty study (ClinicalTrials.gov, NCT01255540), and to identify independent predictors of revascularisation. METHODS:Patients of ?80 years old with non-ST-elevation myocardial infarction and unstable angina pectoris were randomised to an invasive or conservative strategy. Angiographic and procedural results were recorded. Univariate and multivariate analyses were performed to explore variables predicting revascularisation. RESULTS:Among 229 patients in the invasive group, 220 underwent immediate coronary angiography (90% performed via the radial artery). Of these patients, 48% had three-vessel disease or left main stenosis, 18% two-vessel disease, 16% one-vessel disease, 17% minor coronary vessel wall changes and two patients had normal coronary arteries. Six patients (3%) underwent coronary artery bypass graft. Percutaneous coronary intervention (PCI) was performed in 107 patients (49%), with 57% treated with bare metal stents, 37% drug-eluting stents and 6% balloon angioplasty. On average, 1.7 lesions were treated and 2 stents delivered per patient. Complications included 1 major PCI-related bleeding (successfully treated), 2 minor access site-related bleedings, 3 side branch occlusions during PCI and 11 periprocedural myocardial infarctions (considered end points). Sex, bundle branch block and smoking were independent predictors of revascularisation. CONCLUSIONS:PCI was performed in approximately half of the patients, similar to findings in younger populations. Procedural success was high, with few complications. TRIAL REGISTRATION NUMBER:NCT01255540.

Project description:Objective: Dazhu hongjingtian [DZHJT, Rhodiola wallichiana var. cholaensis (Praeger) S.H. Fu] preparation as an add-on therapy has been applied to the treatment of angina pectoris. We aimed to evaluate the efficacy and safety of DZHJT as adjuvant therapy for the treatment of unstable angina pectoris (UAP). Methods: An extensive literature search was conducted on PubMed, Emase, Cochrane Library, Wanfang, CNKI, and VIP databases from inception to January 2019. Randomized controlled trials (RCTs) comparing DZHJT in combination with Western medicine with Western medicine alone were included. Two authors independently performed the literature search, data extraction and risk of bias assessment of included studies, and conducted the statistical analysis. Results: A total of 18 RCTs involving 1,679 patients were included in the meta-analysis. Adjuvant treatment with DZHJT significantly decreased ?80% reduction in the frequency of angina attacks [risk ratio (RR) 1.57; 95% CI 1.36-1.81], weekly frequency of angina attacks [mean difference (MD) -1.03 times; 95% confidence interval (CI) -1.51 to -0.55], marked improved abnormal electrocardiogram (RR 1.46; 95% CI 1.23-1.74). In addition, DZHJT significantly reduced the whole-blood viscosity (MD -0.70 mPa.s; 95% CI -0.84 to -0.55), plasma viscosity (MD -0.28 mPa.s; 95% CI -0.38 to -0.19), serum level of fibrinogen (MD -0.67 g/L; 95% CI -0.79 to -0.54), thromboxanes B2 (MD -14.01 ng/L; 95% CI -20.86 to -7.15), and C-reactive protein (MD -1.48 mg/L; 95% CI -2.72 to -0.25). No significant differences in headache/dizziness (RR 0.72; 95% CI 0.31-1.67) were observed between two groups. Conclusion: Adjuvant treatment with DZHJT has an add-on effect in reducing angina pectoris attacks in patients with UAP. The beneficial effect may be correlated with regulating whole-blood viscosity, plasma viscosity, fibrinogen, thromboxanes B2, and CRP level. However, future well-designed prospective, randomized, double-blind placebo-controlled trials with large sample sizes are required to evaluate the evidence.
