Impedance Cardiography-Guided Treatment of Hypertension: A Review of the Literature.
Bibliographic record
Abstract
BACKGROUND: Hypertension occurs when regulatory mechanisms fail, resulting in increased cardiac output (CO) and/or increased systemic vascular resistance (SVR). Impedance cardiography (ICG) is a non-invasive technology that measures CO and SVR. OBJECTIVE: To assess the literature related to the use of ICG in guiding the selection of anti-hypertensive medications in individuals with hypertension. DESIGN: PubMed and Cumulative Index to Nursing and Allied Health Literature databases were searched for pertinent literature. Only English language, primary research reports published between 1990 and 2014 were included. FINDINGS: The literature demonstrated significant reduction of blood pressure among participants who were treated with ICG-guided selection of anti-hypertensive medications when compared to standard treatment. CONCLUSION: Although the research reviewed is not without limitations (e.g., small sample sizes and small effect sizes), individualized pharmacologic treatment of uncontrolled hypertension based on ICG-obtained hemodynamics seems successful in reducing blood pressure. Further research within the Canadian context that addresses the limitations is warranted.

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.
