Table 6. Long-term outcomes by homocysteine quintiles.
| Patient number | HCY range | Event number | Event rate | * Adjusted HR | 95% CI | P value | |
|---|---|---|---|---|---|---|---|
| Quintile 1–3 | 789 | < 11.3 | 201 | 25.4 | 1 | – | – |
| Quintile 4 | 293 | 11.3–13.4 | 84 | 28.7 | 1.06 | 0.78~1.44 | 0.697 |
| Quintile 5 | 206 | > 13.4 | 75 | 36.4 | 1.37 | 1.03~1.82 | 0.032 |
Adjusted HR: hazard ratio adjusted for age, sex, hypertension, diabetes mellitus, hyperlipidemia, serum creatinine, multi-vessel disease, post procedure MLD, and LVEF < 40%
HCY: plasma total homocysteine level. LVEF: left ventricular ejection fraction; MLD: minimal luminal diameter.
