[Efficacy of shock-wave therapy in the treatment of chronic ischemic heart failure].
Bibliographic record
Abstract
INTRODUCTION: Shock-wave therapy (SWT) has proved its efficacy and safety in a number of studies in stable effort angina. METHODS: Twenty-four patients (20 men, 4 women; mean age 63.3 +/- 6.1 years) with chronic heart failure (CHF) of ischemic origin (>6 months after AMI) and left ventricular (LV) ejection fraction (EF) <40% received SWT in addition to their stable treatment. SWT was performed in 9 sessions with 100 shocks per spot in viable segments detected by low dose dobutamine stress echocardiography. Patients were examined at baseline and at 3 and 6 months after SWT. Troponin T level was measured after each week of treatment. RESULTS: Class of CHF significantly decrease from 2.2 +/- 0.8 to 1.7 +/- 0.7 at 3 and at 6 months after SWT (p<0.01). Six-minute walk test improved from 414 +/- 141 to 509 +/- 141 and 538 +/- 116 m (p<0.01) at 3 and 6 months, respectively. Significant augmentation of LVEF at rest was noted at 3 and 6 months after SWT (from 32.2 +/- 6.0 to 34.8 +/- 9.6 and 37.7 +/- 9.5, respectively p=0.03). Troponin T was negative in all cases. Significant increase of LV longitudinal deformation was registered at 6 months (from -8.84 +/- 0.38 to -9.72 +/- -0.44%, p<0.01) what evidenced for improvement of LV contractility. The latter was a result of restored hibernating segments function (longitudinal deformation of these segments rose from initial -7.52 +/- -0.5 to -9.18 +/- 0.53 and -9.63 +/- 0.59% at 3 and 6 months after SWT, respectively, p<0.01). CONCLUSIONS: In patients with CHF SWT caused significant clinical improvement as well as increases in LV EF and distance walked during 6-min walk test. These results justify conduct of a placebo controlled study.

How this classification was reachedexpand
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; a candidate call from one teacher head, not a consensus.
