Reprising Ramadan-Related Angina Pectoris: A Potential Strategy for Risk Reduction
Bibliographic record
Abstract
BACKGROUND A preponderance of evidence supports short-term aspirin usage to reduce transiently increased cardiovascular risk in clinical conditions that promote acute myocardial ischemia. CASE REPORT We report on the case of a 69-year-old male of Muslim Indian heritage with multiple cardiovascular risk factors who experienced the onset of angina pectoris while fasting for Ramadan for more than 16 hours daily for 30 days in July 2015. While symptom free for 2 months on medical management after ending his fast, he underwent quadruple coronary artery bypass surgery for severe 4-vessel disease following an acute anterior myocardial infarction. A percutaneous coronary intervention with stent placement was subsequently required for persistent myocardial ischemia on stress-MIBI testing due to occlusion of the graft to left anterior descending artery. Presently asymptomatic, he decided to forgo fasting for Ramadan in June 2016. CONCLUSIONS Based on this case, measures for primary cardiovascular prevention among the 1.2 billion susceptible males at similar high short-term cardiac risk while fasting for Ramadan are proposed. The value of aspirin for attenuating high short-term cardiovascular risk in clinical conditions conferring transient inflammatory stress is considered. Low-dose aspirin usage at evening meals while fasting for Ramadan is prudent for primary cardiovascular protection of males who may have non-obstructive coronary atherosclerosis to mitigate the risk for rupture of potentially vulnerable plaques. Based in part on conclusive evidence for protection of middle-aged males from first myocardial infarction in a randomized prospective primary prevention trial, this measure is concordant with recommendations from sub-specialty societies for primary cardiovascular prevention for persons at above-average risk demonstrated by validated biomarkers and from the United States Preventive Services Task Force.

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.
