Task: Answer Verification
Input (English): Question: Does methionine loading enhance the predictive value of homocysteine serum testing for all-cause mortality or major adverse cardiac events?
Answer: The presence of post-methionine hyperhomocysteinaemia did not significantly alter risk of death or MACE in patients with normal or increased fasting homocysteine levels, respectively. In conclusion, methionine loading does not improve the predictive value of homocysteine testing with regard to long-term mortality or MACE.
Output (English): no
