Key result
Ticagrelor and clopidogrel were both effective in reducing LDL levels after two months of treatment, with no significant difference in the magnitude of reduction between the two groups.
Why the study?
Existing research suggests potential benefits of ticagrelor over clopidogrel, but there is limited comparative data within the Iranian population post-angiography.
Does ticagrelor improve laboratory parameters, adherence, and side effects compared to clopidogrel in ACS patients post-PCI?
RCT (n=200)
Stratified by age, gender, and cardiac disease type
Yes
Does ticagrelor improve laboratory parameters, adherence, and side effects compared to clopidogrel in ACS patients post-PCI?
In Iranian ACS patients post-PCI, ticagrelor showed a more pronounced reduction in CRP levels compared to clopidogrel at 2 months, suggesting potential anti-inflammatory benefits.
Ticagrelor may confer greater CRP reduction than clopidogrel post-PCI; extends evidence to Iranian ACS patients but needs confirmation in larger RCTs.
Background: Acute coronary syndrome (ACS) remains a critical health concern, with patient outcomes significantly influenced by the selection of antiplatelet therapy post-percutaneous coronary intervention (PCI). Existing research suggests potential benefits of ticagrelor over clopidogrel in reducing cardiovascular events. However, there is limited comparative data within the Iranian population post-angiography. Objectives: This research aimed to compare laboratory findings, adherence rates, and side effects following the administration of ticagrelor and clopidogrel in ACS patients post-PCI. Methods: A case-control study was conducted to assess the impacts of antiplatelet therapy in 200 ACS patients undergoing PCI at Masih Daneshvari Hospital, Tehran, Iran. Patients were stratified into two groups, matched by age, gender, and type of cardiac disease. One group received clopidogrel, and the other received ticagrelor. Laboratory parameters, including HDL, LDL, and CRP, were evaluated at baseline and two months after treatment initiation. Additionally, adverse effects and medication adherence were assessed to evaluate the safety and efficacy of the two antiplatelet agents. Results: The study enrolled 200 ACS patients post-PCI, with 54% male and 46% female. The age range was 38 to 84 years, with a mean age of 63.07 ± 12.54 years. Of the patients, 76% had non-ST-elevation myocardial infarction (NSTEMI), while 24% had ST-elevation myocardial infarction (STEMI). Among STEMI patients, 56.25% were treated with fibrinolytics, and 43.75% underwent primary PCI. Common adverse events included dyspnea, bleeding, and gastrointestinal symptoms. Both the ticagrelor and clopidogrel groups showed reductions in LDL levels from baseline to the two-month follow-up. Conclusions: Ticagrelor and clopidogrel were both effective in reducing LDL levels after two months of treatment. However, ticagrelor demonstrated a more pronounced decrease in CRP levels, indicating potential anti-inflammatory benefits. These findings provide insight into antiplatelet therapy's role in managing ACS patients post-PCI.

Hamrahi et al. (2024) conducted an RCT in Acute Coronary Syndrome (n=200). Ticagrelor vs. Clopidogrel was evaluated on Reduction in LDL levels at 2 months (p=0.110). Ticagrelor and clopidogrel were both effective in reducing LDL levels after two months of treatment, with no significant difference in the magnitude of reduction between the two groups.
