An observational study in Ischemic Stroke, TIA (Transient Ischemic Attack) and Clopidogrel Resistance, sponsored by Nanjing First Hospital, Nanjing Medical University. Not yet recruiting. Open to participants aged 18 Years to 80 Years. Per ClinicalTrials.gov, last updated 2024-12-31.
Sponsored by Nanjing First Hospital, Nanjing Medical University · Observational
The goal of this observational study is to explore the potential efficacy of related biomakers in predicting clopidogrel resistance in patients with ischemic stroke. To be specific :
2,612 studies on the registry are indexed under Ischemic Stroke; 971 are open to participants now.
This study's planned enrollment of 800 is above the median of 300 across 771 observational studies indexed under Ischemic Stroke.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A “mini-stroke”: temporary stroke-like symptoms caused by reduced blood flow to part of the brain, spinal cord or eye, without signs of a new stroke on a scan.
Stroke symptoms need emergency care at once, even if they go away.
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Definition of clopidogrel resistance (quantitative indicator): After patients take clopidogrel: 1. The maximum platelet aggregation rate (%) value is greater than 50%; 2. Compared before and after, clopidogrel inhibits platelet aggregation by less than 20%; 3. The platelet aggregation inhibition of clopidogrel is 5 ohms or more (resistance method).
Recurrent new stroke within 90 days after antiplatelet therapy (stroke recurrence)
Time frame: From enrollment to the end of treatment at 90 days
