Effect of bariatric surgery on blood pressure response to exercise in a severely obese population
Bibliographic record
Abstract
BACKGROUND: Exaggerated blood pressure response to exercise is a cardiovascular risk factor associated to higher morbidity and mortality. Severely obese patients have an increased risk of exercise-induced hypertension (EIH). We aimed to assess the blood pressure response to exercise in patients with severe obesity who underwent bariatric surgery as well as the main determinants of this response. METHODS: We used data from the ACTIVE clinical trial, in which 60 severely obese patients who underwent bariatric surgery were enrolled. Anthropometric measurements, abdominal and mid-thigh computed tomography scans and maximal exercise testing were performed before bariatric surgery, as well as 3 and 6 months post-surgery. EIH was defined as a maximal SBP ≥210 mmHg for men and ≥190 mmHg for women. RESULTS: At baseline, 62% of patients had EIH. At 6 months, we observed an EIH resolution rate of 39%. The main determinant of EIH resolution was sex. Actually, patients with EIH resolution were mostly women without resting hypertension and a lower amount of visceral adipose tissue. CONCLUSION: These results suggest that bariatric surgery is efficient to resolve EIH, particularly in women with initially a better anthropometric profile.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
