Abstract

fetched live from OpenAlex

Worldwide, a significant number of patients have coronary artery disease (CAD). Many such patients end up with heart failure or impaired myocardial function from ischemia or obstruction resulting from multivessel atherosclerosis. There have been many advances in both pharmacological and myocardial revascularization techniques. As a result, the survival of patients has increased after myocardial infarction, which has led to an increased number of patients with debilitating symptoms of chronic refractory angina and ischemic heart disease. Refractory angina pectoris is chronic angina that is not responsive to maximum medical therapies and standard revascularization via coronary artery bypass (CABG) surgery or percutaneous coronary angioplasty (PCA).A subgroup of ischemic heart disease and angina patients can not be treated successfully despite optimal medical management and standard revascularization. For these patients, some advanced therapeutic options have been clinically tested, including transmyocardial laser revascularization, transcutaneous electrical nerve stimulation, or angiogenesis by gene or cell therapy.Transmyocardial laser extravascular angiogenesis (TMLR) has emerged as an option in patients suffering from chronic refractory angina that can improve both patients’ symptoms, exercise capacity, quality of life, and decrease their cardiac rehospitalization. TMLR was approved by the US Food and Drug Administration (FDA) in 1998 to treat moderate to severe angina that occurred due to CAD, and that is nonresponsive to standard revascularization and maximal medical therapy. However, this technique was already in clinical use starting in 1983 in association with CABG as a hybrid technique. In this procedure, the laser is used directly on the surface of the heart to revascularize it.It is important to note that recently all the trials pertaining to TMLR have been closely examined. It was also found that many studies that assessed subjective improvement fromTMLR lacked blinding. Many randomized clinical trials that examined TMLR also did not use important pre-defined outcomes such as myocardial infarction, arrhythmia, or congestive heart failure, which are examined in most practice-changing RCTs in cardiology. Based on current guidelines, for the management of refractory angina, the ACC/AHA guidelines do not recommend TMLR with or without CABG.

Teacher imitation

Not 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.
