Giriş:
Kararlı anjina pektorisli hastalarda, metabolik bir
anti-iskemik ilaç olan trimetazidin (TMZ) tedavisinin risk faktörü olarak kabul
edilen lipoprotein ilişkili fosfolipaz A₂ (Lp-PLA₂) düzeyi ve egzersiz parametreleri üzerine etkisi
araştırıldı.

Hastalar
ve Yöntem: Egzersiz testi pozitif olan
kararlı anjina pektorisli 30 hasta (ort. yaş 62.1 ± 8.3; dağılım 47-77)
çalışmaya alındı. Trimetazidin tedavisi öncesinde Lp-PLA₂ düzeyleri ölçüldü; 12 haftalık TMZ tedavisi sonrasında
egzersiz testi ve Lp-PLA₂ ölçümleri tekrarlandı.

Bulgular:
Trimetazidin tedavisi sonrasında Lp-PLA₂ düzeyleri anlamlı düşüş (p= 0.006), egzersiz iş yükü
anlamlı artış (p= 0.048) gösterdi.

Sonuç: Trimetazidin tedavisi kardiyak
metabolizma değişikliği sonucu serbest oksijen radikal oluşumunu ve
enflamasyonu azaltarak Lp-PLA₂
düzeyinde anlamlı düşüş sağlamaktadır. Bu bulgu, egzersiz parametrelerindeki
iyileşmelerle birlikte, TMZ tedavisinin kararlı anjina pektorisli hastaların
prognozunda olumlu katkı sağlayabileceğini göstermektedir.

Effects of Trimetazidine Treatment on the Lipoprotein-Associated Phospholipase A2 Level and Exercise Parameters in Patients with Stable Angina Pectoris

Öz

Introduction:
We examined the clinical effectiveness of trimetazidine
(TMZ), a metabolic anti-ischemic agent, on lipoprotein-associated phospholipase
A₂ (Lp-PLA₂) levels, which is considered a risk factor
for cardiovascular events, and on exercise parameters in patients with stable
angina pectoris (SAP).

Patients
and Methods: The study included 30 patients (mean age 62.1
± 8.3 years; range 47 to 77 years) with SAP and a positive exercise test
result. Serum Lp-PLA₂ levels were measured at baseline. Exercise
testing and Lp-PLA₂ measurements were repeated after at least 12
weeks of TMZ treatment.

Results: After
TMZ treatment, Lp-PLA₂ levels decreased significantly (p= 0.006),
and workload increased significantly (p= 0.048).

Conclusion:
Trimetazidine treatment reduces serum Lp-PLA₂
levels via shifting cardiac metabolism, resulting in decreased production of
free oxygen radicals and inflammation. This finding, together with improvements
in exercise test parameters, suggests that TMZ may have a beneficial effect on
the prognosis of patients with SAP.
