Daily and intermittent rosuvastatin 5 mg therapy in statin intolerant patients: an observational study
Bibliographic record
Abstract
OBJECTIVE: To examine the efficacy and tolerability of rosuvastatin 5 mg at daily and non-daily dosing regimens. RESEARCH DESIGN AND METHODS: A retrospective survey was conducted at nine primary, secondary and tertiary healthcare centres in the United Kingdom. MAIN OUTCOME MEASURES: Changes in lipid fractions from baseline values after more than 3 months' treatment. RESULTS: A total of 325 patients were identified. These patients were aged 63 ± 10 years, 50% male and prescription was mostly for primary prevention of cardiovascular disease (CVD) (59%). Co-morbidities included: established CVD present in 41%, type 2 diabetes mellitus (15%), hypertension (74%) and smoking (9%). Adverse effects had been documented to simvastatin (75%) or atorvastatin (63%). A total of 289 patients (89%) tolerated rosuvastatin well and were still adherent after a median follow-up of 14.9 (3-79) months. The remainder (n = 36; 11%) discontinued the medication after median 5 months' treatment due to adverse effects. Efficacy was assessed in 224 patients who had adequate data. Baseline lipids were total cholesterol (TC) 7.41 ± 1.50 mmol/L, triglycerides (TG) 2.26 (range 0.36-18.4) mmol/L; high density lipoprotein cholesterol (HDL-C) 1.43 ± 0.47 mmol/L and low density lipoprotein cholesterol (LDL-C) 4.76 ± 1.38 mmol/L. Daily rosuvastatin (n = 134) reduced mean TC by 31%, TG 15% and LDL-C 43% (p < 0.001). Rosuvastatin 5 mg 2-3 times weekly (n = 79) reduced TC 26%, TG 16% and LDL-C 32% (p < 0.001). Weekly rosuvastatin (n = 11) reduced TC 17%, LDL-C by 23% (p < 0.001) but had no effect on TGs. Targets were attained in 17% of CHD-risk equivalent patients and 41% of primary prevention patients by National Cholesterol Education Program criteria and 27% and 68% using UK targets. No myositis or rhabdomyolysis was observed and alanine aminotransferase (ALT) and creatine kinase (CK) were similar to baseline. CONCLUSIONS: In this retrospective observational multicentre study, rosuvastatin 5 mg was found to be safe and biochemically effective either as daily or intermittent therapy in patients intolerant to other conventional statin regimens.

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.
