  • necrosis
  • Acute myocardial infarct (MI), commonly known as a heart attack, is a condition characterized by ischemic injury and necrosis of the cardiac muscle. (medscape.com)
  • Troponin, on the other hand, has 100 % cardio-specificity, but its concentration takes time to increase after myocardial necrosis has occurred. (biomedsearch.com)
  • To ensure there is ischemia-related myocardial necrosis, the universal definition of AMI requires "a rise and/or fall of cardiac biomarker values [preferably cardiac troponin (cTn)] with at least one value above the 99th percentile upper reference limit (URL)" [ 3 ], and thus serial troponin measurements within a timeframe of 3-6 h. (biomedsearch.com)
  • The pathophysiological mechanism of MC post AMI is complete lack of perfusion leading to myocardial necrosis, neutrophil infiltration, activation of matrix metalloproteinases (MMPS) and degradation of collagen struts by serine protease leading to slippage of myocytes, wall thinning, increased wall stress and ventricular dilatation, and finally wall disruption and rupture.

  • incidence
  • The purpose of this study was to examine the incidence of ischemic stroke during the first month after an acute MI in an unselected population, to identify predictors of MI-related stroke, and to investigate the secular trend in MI-related stroke incidence. (ahajournals.org)
  • 5 Moreover, the routine use of thrombolytic therapy and aspirin for acute MI has not changed the incidence of left ventricular thrombi but may have influenced the risk for embolism. (ahajournals.org)
  • The aims of the present study were to examine the secular trend in the incidence of ischemic stroke the first month after acute MI in an unselected population, to study the time relationship between MI and stroke, to identify risk factors for MI-related stroke, and to study the long-term prognosis.

  • Stents
  • After placement of two bare-metal stents, TIMI grade 3 (normal) flow with limited myocardial blush was observed (Figure 2 ). (hindawi.com)
  • Outcome
  • Perers E, Caidahl K, Herlitz J, Karlson BW, Karlsson T, Hartford M. Treatment and short-term outcome in women and men with acute coronary syndromes. (freemd.com)
  • severe
  • The concentration of copeptin, the C-terminal part of pro-arginine vasopressin, has been shown to increase early after acute and severe events. (biomedsearch.com)
  • inferior
  • Early contrast-enhanced CMR confirmed the presence of microvascular obstruction in the acute inferior infarct and demonstrated a large burden of thrombus within the pseudoaneurysm. (ahajournals.org)
  • injury
  • In patients who would have survived despite reperfusion therapy, use of this treatment should lead to greater myocardial salvage and a reduced extent of ventricular injury in many. (ahajournals.org)
  • These findings suggest that cholesterol crystals could play a critical role in plaque rupture, as well as vascular and myocardial injury. (ingentaconnect.com)
  • aneurysm
  • A pseudoaneurysm, or false aneurysm, develops after an acute MI that is complicated by a ventricular free wall rupture that is contained by localized pericardial adhesions. (uptodate.com)
  • treatment
  • Imaging is also useful in detecting pericardial effusion, concomitant valvular or congenital heart disease, and marked depression of ventricular function that may interdict treatment in the acute phase with beta-adrenergic blockers. (medscape.com)
