Longitudinal Changes in Central Artery Stiffness with Lifestyle Modification, Washout, and Drug Treatment in Individuals at Risk for Cardiovascular Disease
Bibliographic record
Abstract
We assessed 17 middle-aged and older individuals (58.0 +/- 7.9 years, 7 females) at risk for cardiovascular disease regarding: (1) Whether carotid artery stiffness (cAS) would be reduced with a 1-year lifestyle modification program, (2) to what degree cAS would return following washout (mean of 26.9 +/- 4.0 months) from the active intervention, and (3) whether a 24-week telmisartan treatment would reduce cAS more than our lifestyle modification program. cAS by Doppler ultrasound, cardiovascular disease risk factors, and exercise capacity were assessed at three points: Following the 1-year lifestyle modification, following the washout period, and following a 24-week telmisartan treatment. Following telmisartan, systolic blood pressure (SBP) was significantly decreased (114.8 +/- 12.3 mmHg) compared to baseline (127.9 +/- 12.7 mmHg) and following the washout period (126.1 +/- 14.9 mmHg). Similarly, diastolic blood pressure (DBP) was significantly lower following telmisaratn than following the washout period. Exercise capacity was increased following lifestyle modification but returned to the baseline level following the washout period. Following the lifestyle modification program, cAS was significantly reduced, and this reduction was maintained following the washout period. Conversely, the subsequent telmisartan treatment did not change cAS despite a significant blood pressure reduction. These results suggest that the reduced cAS achieved with lifestyle modification may not necessarily disappear following a cessation of the active program, indicating a possible role that family physicians can play in their clinical practice, and also providing a further rationale to promote lifestyle modification as an initial therapy for this population. In contrast, no additional benefit of telmisartan beyond our lifestyle intervention was observed in this 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.
