Effect of cardiac shock wave therapy plus optimal medical therapy on rehospitalization in patients with severe coronary artery disease: A meta-analysis and trial sequential analysis
Bibliographic record
Abstract
Objective: Several small sample-sized clinical studies have demonstrated that cardiac shock wave therapy (CSWT) might reduce the risk of rehospitalization in patients with severe coronary artery disease (CAD). However, other observational studies did not reported that clinical benefit of CSWT. Therefore, the effect of CSWT plus optimal medical therapy (OMT) on rehospitalization is still controversial. Methods: We performed an updated meta-analysis and systematic review of randomized clinical trials (RCTs) and prospective cohort studies identified in systematic searches of Pubmed, Embase, the Cochrane library, the ClinicalTrials.gov website and Chinese SinoMed Database (up to December 2021). Primary endpoint was the rate of major adverse cardiac events (MACEs, the composite outcome of mortality, coronary artery revascularization, and rehospitalization). Meta-regression and subgroup analyses were used to identify possible contributors to between-study variances in the HDRS. Required information size (RIS) was calculated with trial sequential analysis (TSA). Results: A total of 11 RCTs and 5 prospective cohort studies involving 1,149 patients with a mean follow-up of 10.3 months (range 3-72) months were included. Overall, CSWT plus OMT significantly decreased the rate of MACEs compared with the OMT group (RR, 0.39; 95% CI, 0.29-0.53), which was mainly attributed to markedly lower risk of rehospitalization (RR, 0.37; 95% CI, 0.27-0.51). Subgroup analysis showed that the pooled RRs for MACEs was significantly lower in studies enrolling patients with higher baseline Canadian Cardiovascular Society angina class (≥2.2) (RR, 0.36; 95% CI, 0.26-0.50) or studies with short follow-up period (followed ≤ 6 months, RR, 0.39; 95% CI, 0.24-0.64; followed 7-12 months, RR, 0.38; 95% CI, 0.26-0.54) or studies with HF with reduced ejection fraction (RR, 0.31; 95% CI, 0.13-0.72) or with preserved ejection fraction (RR, 0.40; 95% CI, 0.29-0.56). TSA showed that The RIS for MACE was 935, and the accrued information size was 577. Conclusion: Cardiac shock wave therapy plus OMT could decrease the rate of rehospitalization among patients with severe CAD. However, this result must be interpreted with caution, for the evidence supporting the use of CSWT for severe CAD is limited by the small sample size and short follow-up period of previous studies. Larger RCTs with longer follow-up are warranted to confirm these findings. Systematic review registration: [https://inplasy.com/], identifier [INPLASY202210103].

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
