Early Invasive Strategy for Unstable Angina: a New Meta-Analysis of Old Clinical Trials.

ABSTRACT: Randomized controlled trials (RCTs) were conflicting to support whether unstable angina versus non-ST-elevation myocardial infarction (UA/NSTEMI) patients best undergo early invasive or a conservative revascularization strategy. RCTs with cardiac biomarkers, in MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials from 1975-2013 were reviewed considering all cause mortality, recurrent non-fatal myocardial infarction (MI) and their combination. Follow-up lasted from 6-24 months and the use of routine invasive strategy up to its end was associated with a significantly lower composite of all-cause mortality and recurrent non-fatal MI (Relative Risk [RR] 0.79; 95% confidence interval [CI], 0.70-0.90) in UA/NSTEMI. In NSTEMI, by the invasive strategy, there was no benefit (RR 1.19; 95%?CI, 1.03-1.38). In the shorter time period, from randomization to discharge, a routine invasive strategy was associated with significantly higher odds of the combined end-point among UA/NSTEMI (RR 1.29; 95%?CI, 1.05-1.58) and NSTEMI (RR 1.82; 95%?CI, 1.34-2.48) patients. Therefore, in trials recruiting a large number of UA patients, by routine invasive strategy the largest benefit was seen, whereas in NSTEMI patients death and non-fatal MI were not lowered. Routine invasive treatment in UA patients is accordingly supported by the present study.

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.

Project description:BackgroundWidespread implementation of the minimally invasive technique in pancreatic surgery has proven to be challenging. The aim of this study was to compare the perioperative outcomes of minimally invasive (laparoscopic and robotic) pancreatic surgery with open pancreatic surgery using data obtained from RCTs.MethodsA literature search was done using Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, and Web of Science; all available RCTs comparing minimally invasive pancreatic surgery and open pancreatic surgery in adults requiring elective distal pancreatectomy or partial pancreatoduodenectomy were included. Outcomes were mortality rate, general and pancreatic surgery specific morbidity rate, and length of hospital stay.ResultsSix RCTs with 984 patients were included; 99.0 per cent (486) of minimally invasive procedures were performed laparoscopically and 1.0 per cent (five) robotically. In minimally invasive pancreatic surgery, length of hospital stay (-1.3 days, -2 to -0.5, P = 0.001) and intraoperative blood loss (-137 ml, -182 to -92, P < 0.001) were reduced. In the subgroup analysis, reduction in length of hospital stay was only present for minimally invasive distal pancreatectomy (-2 days, -2.3 to -1.7, P < 0.001). A minimally invasive approach showed reductions in surgical site infections (OR 0.4, 0.1 to 0.96, P = 0.040) and intraoperative blood loss (-131 ml, -173 to -89, P < 0.001) with a 75 min longer duration of surgery (42 to 108 min, P < 0.001) only in partial pancreatoduodenectomy. No significant differences were found with regards to mortality rate and postoperative complications.ConclusionThis meta-analysis presents level 1 evidence of reduced length of hospital stay and intraoperative blood loss in minimally invasive pancreatic surgery compared with open pancreatic surgery. Morbidity rate and mortality rate were comparable, but longer duration of surgery in minimally invasive partial pancreatoduodenectomy hints that this technique in partial pancreatoduodenectomy is technically more challenging than in distal pancreatectomy.
