| Study objectives | Homocysteine is a sulphur-containing amino acid derived from the demethylation of methionine. Increased plasma homocysteine level has been recognised as a risk factor for cardiovascular diseases. Non-ST Elevation Myocardial Infarction (NSTEMI) and Unstable Angina (UA) belong to the spectrum of Acute Coronary Syndromes (ACS) that implies partial occlusion of the coronaries leading to ischaemic events. Unstable angina and NSTEMI have high recurrence rates for ACS and mortality six months after the event. Blood homocysteine levels are higher in patients with unstable angina, and it has been implicated to poorer outcomes and greater myocardial injury. Low homocysteine level confers better long-term outcomes among patients with coronary heart disease. Folic acid is a potent homocysteine-lowering agent. It is used in several clinical trials to assess reduction of outcomes in subjects with cardiovascular disease. Hypothesis: Homocysteine-lowering could reduce subsequent clinical events, such as mortality and the composite outcomes of mortality, nonfatal acute coronary syndrome and other serious re-hospitalisation in people with UA or NSTEMI. |

Haemodynamic instability (cardiogenic shock, ongoing chest pain, unresolved and new onset end-organ damage, and unstable congestive heart failure in the past two weeks) 2. Significant liver disease (classical signs and symptoms, or three times the upper limit of normal in liver enzymes, or a deranged Prothrombin Time [PT] 1.5 x normal not explained by anticoagulant intake) 3. Significant renal disease (with creatinine levels more than 180 µmol/dl or requiring dialysis) 4. Haemoglobin less than 1 g/dl 5. High output failure 6. Could not provide adequate self-care 7. Malignancy or any terminal illness 8. Pregnancy 10. Could not provide independent informed consent 11. Living outside Metro Manila or the adjacent provinces of Cavite and Rizal |
