Chronic treatment with ticagrelor limits myocardial infarct size: an adenosine and cyclooxygenase-2-dependent effect.

OBJECTIVE In a phase III clinical trial (PLATelet inhibition and patient Outcomes, PLATO), ticagrelor provided better clinical outcomes than clopidogrel in patients with acute coronary syndromes. In addition to P2Y12-receptor antagonism, ticagrelor prevents cell uptake of adenosine and has proven able to augment adenosine effects. Adenosine protects the heart against ischemia-reperfusion injury...

Effects of Ticagrelor on Myocardial Infarct Size

Ticagrelor (Brilinta; AstraZeneca Pharmaceuticals LP, Wilmington, DE, USA) is a direct acting, reversible, oral P2Y12 inhibitor.1) In the PLATelet inhibition and patient Outcomes (PLATO) study, compared to clopidogrel (Plavix; Bristol-Myers Squibb/Sanofi Pharmaceuticals, Bridgewater, NJ, USA), ticagrelor reduced the rate of death from vascular causes, myocardial infarction (MI), or stroke in pa...

Relationship Between Myocardial Infarct Size

We compared myocardial infarct size produced by permanent occlusion of the middle left anterior descending (LAD) or circumflex (LCx) coronary artery in the anesthetized dog. The dogs were killed 3-10 days later, and the occluded coronary bed was visualized by postmortem arteriography. The outlines of the infarct and occluded bed were marked on tracings of weighed left ventricular (LV) rings and...

Myocardial Infarct Size in Humans

Background. The influence of coronary collateral vessels on infarct size in humans remains controversial, partly because no previous study has examined the impact of collaterals present at the onset of acute myocardial infarction on infarct size. Methods and Results. The present study used the data base of the Thrombolysis in Myocardial Infarction (TIMI) Phase I trial to correlate the presence ...

Myocardial Infarct Size and Location

Recent infarcts were compared with the anatomic boundaries of the involved vascular bed in human hearts to determine the amount and location of necrosis in relation to the myocardium at risk. The coronary arteries were injected with BaSo4 in 18 human hearts with 3-16-day-old infarcts. Thin (3-4-mm) slices were cut at 10-15-mm intervals, photographed, x-rayed and used for histologic analysis. In...
