Effect of Upstream High Bolus Dose of Tirofiban in Primary PCI for the Patients With STEMI on Short Term Outcome

2019-10-07 08:56:50 | BioPortfolio


The goal of the study to investigate the impact of upstream HBD of Tirofiban on short outcome of STEMI patient.


- Primary percutaneous coronary intervention (PPCI) is the gold standard of treatment of ST segment elevation myocardial infarction (STEMI).1 PPCI restores thrombolysis in myocardial infarction flow 3 (TIMI 3) in over 90% of patients. However ,there remains a small proportion of patients, who continue to exhibit overt impairment of myocardial reperfusion despite successful opening of infarct related epicardiual artery (IRA). This phenomenon is called no-reflow, which is largely because of severe microvascular obstruction (MVO).

- Belonging to the class of glycoprotein IIb/IIIa inhibitors (GPIs), tirofiban, can be useful in primary PCI for acute coronary syndrome (ACS).1,2The administration of tirofiban is an efficacious treatment option to reduce ischemic events in patients with The ACS and/or those undergoing PCI.2,3 In most guidelines, abciximab is recommended as the drug of first choice4 due to the finding that tirofiban is less effective than abciximab in platelet inhibition within 60 min of intravenous administration. However, some recent systemic reviews of randomized trials have not demonstrated obvious difference between smGPIs (eptifibatide or tirofiban) and abciximab in terms of angiographic, electrocardiographic, and clinical outcomes of patients undergoing primary PCI.5,6 Tirofiban may provide similar efficacy with an improved safety profile when compared with abciximab, particularly with a high‐dose bolus regimen.7,8 In the new guideline, the recommended class of smGPIs has changed from IIb to IIa, but tirofiban remains with a pre‐PCI indication of IIb, B.4 Although early treatment was associated with a significantly better TIMI flow and superior TIMI myocardial perfusion grades (TMPG) in some trials,9,10 no difference in clinical outcome was found between the 2 strategies in later study.11 One potential cost of administration of GPIs could be increased bleeding, although both major bleeding and minor bleeding rate are low in the tirofiban‐treated patients..

Medical and Biotech [MESH] Definitions

An intravenous anesthetic agent which has the advantage of a very rapid onset after infusion or bolus injection plus a very short recovery period of a couple of minutes. (From Smith and Reynard, Textbook of Pharmacology, 1992, 1st ed, p206). Propofol has been used as ANTICONVULSANTS and ANTIEMETICS.

Relief of PAIN, without loss of CONSCIOUSNESS, through ANALGESIC AGENTS administered by the patients. It has been used successfully to control POSTOPERATIVE PAIN, during OBSTETRIC LABOR, after BURNS, and in TERMINAL CARE. The choice of agent, dose, and lockout interval greatly influence effectiveness. The potential for overdose can be minimized by combining small bolus doses with a mandatory interval between successive doses (lockout interval).

Circular innermost layer of the ESOPHAGUS wall that mediates esophageal PERISTALSIS which pushes ingested food bolus toward the stomach.

Administration of the total dose of radiation (RADIATION DOSAGE) in parts, at timed intervals.

Radionuclide ventriculography where a bolus of radionuclide is injected and data are recorded from one pass through the heart ventricle. Left and right ventricular function can be analyzed independently during this technique. First-pass ventriculography is preferred over GATED BLOOD-POOL IMAGING for assessing right ventricular function.
