Abstract
Ischemic stroke is a disease related to abnormal blood flow that leads to brain dysfunction. The early and late phases of the disease are distinguished. A distinction is made between the early and late stages of the disease, and the best effect in treating an ischemic stroke is usually achieved within the first hours after the onset of symptoms. This review looked at studies platelet activity monitoring studies to determine the risks and benefits of various approaches including antiplatelet therapy. A study was conducted on recently published literature based on PRISMA. This review includes 32 research articles directly addressing the importance of monitoring platelet function during antiplatelet therapy (dual or monotherapy) after ischemic stroke. In patients with transient ischemic attack or ischemic stroke, antiplatelet therapy can reduce the risk of stroke by 11–15%, assuming that patients respond well. Secondary prevention results are dependent on platelet reactivity, meaning that patients do not respond equally to antiplatelet therapy. It is very important that aspirin-resistant patients can benefit from the use of dual antiplatelet therapy. The individualized approach to secondary stroke prevention is to administer the most appropriate drug at the correct dose and apply the optimal therapeutic procedure to the individual patient.

Rapid detection of platelet inhibition and dysfunction in traumatic brain injury: A prospective observational study. J Trauma Acute Care Surg 2022; 92:167-176. [PMID: 34629458 PMCID: PMC8677601 DOI: 10.1097/ta.0000000000003427] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2021] [Revised: 09/14/2021] [Accepted: 09/22/2021] [Indexed: 11/25/2022]
Abstract
BACKGROUND Rapid platelet function testing is frequently used to determine platelet function in patients with traumatic intracranial hemorrhage (tICH). Accuracy and clinical significance of decreased platelet response detected by these tests is not well understood. We sought to determine whether VerifyNow and whole blood aggregometry (WBA) can detect poor platelet response and to elucidate its clinical significance for tICH patients. METHODS We prospectively enrolled patients with isolated tICH between 2018 and 2020. Demographics, medical history, injury characteristics, and patient outcomes were recorded. Platelet function was determined by VerifyNow and WBA testing at the time of arrival to the trauma bay and 6 hours later. RESULTS A total of 221 patients were enrolled, including 111 patients on no antiplatelet medication, 78 on aspirin, 6 on clopidogrel, and 26 on aspirin and clopidogrel. In the trauma bay, 29.7% and 67.7% of patients on no antiplatelet medication had poor platelet response on VerifyNow and WBA, respectively. Among patients on aspirin, 72.2% and 82.2% had platelet dysfunction on VerifyNow and WBA. Among patients on clopidogrel, 67.9% and 88.9% had platelet dysfunction on VerifyNow and WBA. Patients with nonresponsive platelets had similar in-hospital mortality (3 [3.0%] vs. 6 [6.3%], p = 0.324), tICH progression (26 [27.1%] vs. 24 [26.1%], p = 0.877), intensive care unit admission rates (34 [34.3%] vs. 38 [40.0%), p = 0.415), and length of stay (3 [interquartile range, 2-8] vs. 3.2 [interquartile range, 2-7], p = 0.818) to those with responsive platelets. Platelet transfusion did not improve platelet response or patient outcomes. CONCLUSION Rapid platelet function testing detects a highly prevalent poor platelet response among patients with tICH, irrespective of antiplatelet medication use. VerifyNow correlated fairly with whole blood aggregometry among patients with tICH and platelet responsiveness detectable by these tests did not correlate with clinical outcomes. In addition, our results suggest that platelet transfusion may not improve clinical outcomes in patients with tICH. LEVEL OF EVIDENCE Diagnostic tests, level II.

The role of viscoelastic testing in assessing peri-interventional platelet function and coagulation. Platelets 2021; 33:520-530.

Abstract
We carried out a literature search in MEDLINE (PubMed) and EMBASE literature databases to provide a concise review of the role of viscoelastic testing in assessing peri-interventional platelet function and coagulation. The search identified 130 articles that were relevant for the review, covering the basic science of VHA and VHA in clinical settings including cardiac surgery, cardiology, neurology, trauma, non-cardiac surgery, obstetrics, liver disease, and COVID-19. Evidence from these articles is used to describe the important role of VHAs and platelet function testing in various peri-interventional setups. VHAs can help us to comprehensively assess the contribution of platelets and coagulation dynamics to clotting at the site-of-care much faster than standard laboratory measures. In addition to standard coagulation tests, VHAs are beneficial in reducing allogeneic transfusion requirements and bleeding, in predicting ischemic events, and improving outcomes in several peri-interventional care settings. Further focused studies are needed to confirm their utility in the peri-interventional case.

Relationship between Inflammation and Aspirin and Clopidogrel Antiplatelet Responses in Acute Ischemic Stroke. J Stroke Cerebrovasc Dis 2015; 25:327-34. [PMID: 26586373 DOI: 10.1016/j.jstrokecerebrovasdis.2015.10.001] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2015] [Revised: 07/18/2015] [Accepted: 10/01/2015] [Indexed: 11/30/2022] Open
Abstract
OBJECTIVE We measured serum levels of proinflammatory/prothrombotic markers P-selectin, CD40L, matrix metalloproteinase 9 (MMP-9), intracellular adhesion molecule 1 (ICAM-1), and interleukin (IL)-6 in ischemic stroke patients, correlating their levels with the results of aspirin (ASA) and clopidogrel antiplatelet responses, using 3 "point of care" platelet function instruments, thromboelastograph (TEG), Accumetrics (ACU), and impedance aggregometer (IMP). METHODS Patients on chronic ASA regimen at the time of stroke were switched to 300 mg clopidogrel loading dose and 75 mg clopidogrel maintenance dose. Serum levels of the aforementioned inflammatory mediators were measured in 51 patients at baseline (on ASA regimen), and at 26 ± 5 hours and 64 ± 18 hours postclopidogrel administration by enzyme-linked immunosorbent assay. RESULTS P-selectin, CD40L, and MMP-9 serum levels were reduced; ICAM-1 and IL-6 serum levels showed no difference postclopidogrel administration relative to baseline. Patients' stratification based on ASA dose showed more significant reductions in P-selectin, CD40L, and MMP-9 serum levels postclopidogrel administration in patients who were on baseline 81 mg ASA, as compared to patients on 325 mg ASA. Measurement with TEG was sensitive for correlating ASA antiplatelet responses to serum levels of inflammatory markers, whereas measurements with ACU and IMP were sensitive for correlating clopidogrel antiplatelet responses to serum levels of inflammatory markers. CONCLUSION Clopidogrel exerts both platelet-dependent and platelet-independent anti-inflammatory effects. The association between platelet function and inflammation depends on the platelet function analyzer, the type of antiplatelet agent, the nature of the inflammatory marker, and the time of measurement relative to the time of drug administration.

Abstract
Poor response to clopidogrel is often associated with recurrent ischemic events, and reliable platelet function tests are needed to identify clopidogrel low response (CLR). The aim of the study was to compare the consistency of VerifyNow P2Y12 and thrombelastography (TEG) in acute ischemic stroke patients treated with clopidogrel. Patients hospitalized in Changhai Hospital from August 2012 to September 2013 and assigned to treatment with a daily 75-mg dose of clopidogrel. The blood samples were taken on the 5-7th day to assess the capability of VerifyNow P2Y12 and TEG for evaluation of clopidogrel response, and all instrument parameters were used to perform correlation analysis. Patients with CLR were detected by using the methods and criteria published earlier (PRU ≥ 230 assayed by VerifyNow P2Y12 or TEG-Inhib% ≤30 % measured by TEG). Totally 58 patients were enrolled for the study and there were wide varieties in parameters of VerifyNow P2Y12 and TEG. Results showed a total of 17 and 9 patients, respectively, identified as CLR assessed by VerifyNow P2Y12 and TEG, but only three patients were detected to be clopidogrel low responders with both tests. The kappa consistency analysis showed poor consistency between VerifyNow P2Y12 and TEG results in terms of CLR (Kappa = -0.0349, p = 0.7730). Linear regression also demonstrated poor correlation between VerifyNow-PRU/VerifyNow-Inhib% and TEG-Inhib% (p = 0.07901 and p = 0.3788, respectively). Our study demonstrated that there was poor correlation between VerifyNow P2Y12 and TEG results, and VerifyNow P2Y12 showed a larger proportion of CLR than TEG.

Abstract
High on-treatment platelet reactivity (HTPR), referred to as a higher than expected platelet reactivity in patients under antiplatelet therapy, could influence outcome in cerebrovascular disease (CVD), but its prevalence and its stability over time is uncertain. Platelet reactivity was assessed in 18 patients with ischemic stroke/transient ischemic attack (TIA) 7 days (D7) and 90 days (D90) after prescription of clopidogrel, using four methods: light transmission aggregometry with 5 μmol/l ADP (LTA-ADP), vasodilator-stimulated phosphoprotein (VASP), Verify Now P2Y12 and platelet function analyzer (PFA) P2Y. HTPR was defined as LTA-ADP more than 46%; PFA-100-P2Y closure time less than 106 s; VerifyNow P2Y12, PRU greater than 235, VASP, PRI greater than 50%. Patients displayed, both at D7 and D90, a marked inhibition of platelet reactivity towards ADP in all tests as compared with reference levels. Correlations between the results obtained with all the tests at D7 and D90 and between measurements on each day in each test were low-to-moderate. The prevalence of HTPR for all the tests was 40% at D7 and 42% at D90. There was a moderate degree of agreement (k statistic < 0.5) between tests with regard to categorizing patients as HTPR/No-HTPR (D7 and D90). The on-clopidogrel platelet reactivity phenotype, HTPR/No-HTPR, remained stable in 55-72% of patients, depending on the test. A high prevalence of HTPR is found among CVD patients treated with clopidogrel and this platelet reactivity phenotype remains over time. There is poor agreement between the different platelet function tests for categorizing the platelet reactivity phenotype in these patients. The new PFA-100 P2Y equals other platelet function assays for evaluating HTPR in CVD.
