succinate/infarction

This laboratory and others have shown that methylprednisolone sodium succinate and betahistine hydrochloride can each reduce the size of experimental myocardial infarct in dogs at six hours. In light of the fact that these two agents probably act via different mechanisms, a study was carried out to

Methylprednisolone sodium succinate (50 mg/kg) was given 30 minutes before or after the start of a 90 minute occlusion of the left circumflex coronary artery (LCX) in one group of dogs. In a second group, methylprednisolone sodium succinate was given 15 minutes after permanent occlusion of the left

This 16-year-old boy presented with acute retrosternal pain possibly representing acute myocardial infarction. Cardiac enzymes were within reference ranges. There were marked increases in metanephrine to 3299 μg/24 h (reference, <400 μg/24 h), normetanephrine to 1309 μg/24 h (reference, 0-390 μg/24

BACKGROUND Ischemia-reperfusion injury following ST-segment-elevation myocardial infarction (STEMI) is a leading determinant of clinical outcome. In experimental models of myocardial ischemia, succinate accumulation leading to mitochondrial dysfunction is a major cause of ischemia-reperfusion

UNASSIGNED Cardiovascular diseases (CVDs) are the leading causes of mortality worldwide. Currently, the best treatment options for myocardial infarction focus on the restoration of blood flow as soon as possible, which include reperfusion therapy, percutaneous coronary intervention, and therapeutic

OBJECTIVE Previous studies demonstrated that pre-treatment with malonate, a reversible inhibitor of succinate dehydrogenase, given before ischaemia, reduces infarct size. However, it is unknown whether administration of malonate may reduce reperfusion injury. RESULTS Isolated mice hearts were

Inhibition of succinate dehydrogenase (SDH) with malonate during reperfusion reduces infarct size in isolated mice hearts submitted to global ischemia. However, malonate has toxic effects that preclude its systemic administration in animals. Here we investigated the effect of intracoronary malonate

The rate of oxidation of NADH and 3-hydroxybutyrate was studied in heart mitochondria after short-term (60 min) occlusion of coronary artery and the subsequent reperfusion. Addition of NAD increased the rate of 3-hydroxybutyrate oxidation, lowered in mitochondria of impaired tissue, but no complete

In consecutive medicolegal material comprising 79 persons, the formazan test revealed recent myocardial infarction in 16 cases (20%). Only 4 of these cases (25%) were demonstrated by macroscopic examination. By means of microscopic examination, the 4 infarctions recognized macroscopically and 5

BACKGROUND The benefit of beta-blockers post-myocardial infarction (MI) was established in the late 1970s. Major advances in the treatment of MI have since occurred. However, patients with chronic heart failure (CHF) were excluded from those trials. The purpose of this study was to assess the effect
