  • acute
  • Occlusive intracoronary thrombus - a thrombus overlying an ulcerated or fissured stenotic plaque causes 90% of transmural acute myocardial infarctions . (factbites.com)
  • After extensive review of patient's clinical presentation, initial coronary angiography images and noninvasive cardiac imaging, it was predominantly felt that she likely had a horizontal fibrous band compressing the coronary segments and causing acute ischemia, injury, and electric instability. (ahajournals.org)
  • We present a case of acute MI, cardiogenic shock, and cardiac arrest caused not by this mechanism, but by embolisation of thrombotic material to the aortic root with transient complete occlusion of the left main stem (LMS) coronary artery. (biomedsearch.com)
  • In severe cases, acute rupture or erosion of atherosclerotic plaques lead to the rapid formation of intravascular thrombi, a process referred to atherothrombosis. (ahajournals.org)
  • The primary purpose of the electrocardiogram is to detect ischemia or acute coronary injury in broad, symptomatic emergency department populations. (wikipedia.org)
  • The 12 lead ECG is used to classify patients into one of three groups: those with ST segment elevation or new bundle branch block (suspicious for acute injury and a possible candidate for acute reperfusion therapy with thrombolytics or primary PCI), those with ST segment depression or T wave inversion (suspicious for ischemia), and those with a so-called non-diagnostic or normal ECG. (wikipedia.org)
  • severe
  • We present two cases of Marines with severe traumatic blast injuries secondary to improvised explosive device attacks whose hospital courses included amputation, massive blood transfusions, and multiple surgeries. (biomedsearch.com)
  • We conclude that the basis of stunning involves decreased cycling rates of myofibrillar cross-bridges and, after more severe ischemia, a reduction in myofilament Ca 2+ sensitivity. (ahajournals.org)
  • occurs
  • Individuals with cocaine overdose should be transported immediately to the nearest emergency department, preferably by ambulance in case cardiac arrest occurs en route. (wikipedia.org)
  • Myocardial stunning is a form of reversible contractile dysfunction that occurs after brief periods of ischemia. (ahajournals.org)
  • 14 A subsequent study using the same model showed that Ca 2+ sensitivity of tension is unchanged during ischemia and that the decrease in Ca 2+ sensitivity occurs during reperfusion. (ahajournals.org)
  • anomaly
  • Most importantly, deep and long bridged segments are significantly more common in patients dying suddenly, suggesting a role for this anomaly in the clinical course and risk stratification of HCM. (ahajournals.org)
  • percutaneous
  • Following a surgical consultation, her LAD myocardial bridge was deemed not amenable to surgical or percutaneous revascularization, and resumption of medical management with calcium channel blockers was recommended. (massgeneral.org)
  • sensitivity
  • For early detection of myocardial necrosis , sensitivity of this laboratory test is superior to that of the creatine kinase-MB (CK-MB). (factbites.com)
  • 15 Taken together, these results demonstrate that Ca 2+ sensitivity of myocardial tension is reduced after reperfusion, and this may account for the depressed contractile function associated with stunning. (ahajournals.org)
  • Ca 2+ sensitivity of isometric tension and the rate of cross-bridge cycling were assessed, since a reduction in either of these properties would likely decrease both tension and the amount of muscle shortening during an individual heartbeat. (ahajournals.org)
  • diagnosis
  • Although very unusual we feel this case highlights an important differential in the diagnosis of anterolateral MI and images similar to those presented here are previously unreported in the literature. (biomedsearch.com)
  • reduction
  • It is now known that hydrogen sulfide has cardioprotective effects in cases of ischemia related to its effects as an endogenous messenger molecule, primarily via its reduction of the rate of cellular metabolism. (wikipedia.org)
  • common
  • Deep MB ≥2mm was present in 25 out of 120 hearts (21%), and significantly more common in SD (21/82, 26%) than non-SD cases (4/38, 10%) (p=0.03). (ahajournals.org)
  • injury
  • Now, the markers most widely used in detection of MI are MB subtype of the enzyme creatine kinase and cardiac troponins T and I as they are more specific for myocardial injury. (wikipedia.org)
  • assess
  • To assess whether, in these cases, accelerated graft disease and failure occur also after surgical revascularization and to verify whether the use of arterial bypass conduits (known to be less susceptible to graft atherosclerosis) can improve the clinical and angiographic results, we designed the present study protocol. (ahajournals.org)
  • incidence
  • The incidence of bleeding during the bridge with tirofiban was 8%, half of them were significant according to BARC classification (2% grade 3A and 2% grade 3B). (fac.org.ar)
  • increase
  • Periprocedural AMI related to myocardial revascularization surgery: increase within the first 48 hours of hsTT greater than 10 times the normal upper limit if the patient presented normal values previously or increase in hsTT greater than 20% if the patient presented high but stable values, or in decrease. (fac.org.ar)
  • seen
  • The interstitium (stroma) is in most of the cases seen as a connecting "device" for the specific structures of an organ. (wikipedia.org)
  • treatment
  • we conducted an observational, prospective, single-center study, including inpatients with recent angioplasty who used tirofiban as a treatment prior to myocardial revascularization surgery, with and without associated valve replacement. (fac.org.ar)
  • This has led in some cases to inefficient competing treatment algorithms. (ahajournals.org)
  • period
  • The events in the bridge and in the postoperative period do not seem to be associated with the use of tirofiban or P2Y12 suspension. (fac.org.ar)
