    ABSTRACT: Congenital absence of the left circumflex artery is a rare anomaly of the coronary arteries. A 52-year-old man who developed acute inferior myocardial infarction underwent coronary angiography which revealed the absence of the left circumflex artery and that the surrounding structures were supplied by the infarct-related super-dominant right coronary artery. Two stents were implanted into the right coronary artery and one stent into the mid portion of the left anterior descending artery. Follow-up coronary angiography at 67 months showed no detectable restenosis, and 64-slice multidetector computed tomography confirmed the absence of the left circumflex artery. The circumflex artery as a terminal extension of a culprit right coronary artery has not been previously reported.

    ABSTRACT: Platelets play an important role in the development of acute coronary syndromes. Evidence indicates that platelet-inhibiting drugs, such as glycoprotein IIb/IIIa inhibitors, can be beneficial when they are administered at the time of primary percutaneous coronary intervention for acute ST-segment-elevation myocardial infarction. However, an associated increase in the risk of bleeding is well documented. Diffuse alveolar hemorrhage is a rare but life-threatening and underdiagnosed complication of therapy with glycoprotein IIb/IIIa inhibitors. Diffuse alveolar hemorrhage can easily be mistaken for acute pulmonary edema, a condition commonly seen in patients with acute coronary syndrome. Physicians need to be aware of this diagnostic dilemma, because early treatment increases the chance that the patients will survive.Herein, we report the fatal outcome of diffuse alveolar hemorrhage in a 73-year-old man who presented with acute ST-segment-elevation myocardial infarction and was treated with tirofiban in conjunction with primary percutaneous coronary intervention. In addition, we review the medical literature pertaining to the sequelae of glycoprotein IIb/IIIa inhibitor therapy in the presence of diffuse alveolar hemorrhage.

    ABSTRACT: Hyperglycemia on admission is a predictor of an unfavorable prognosis in patients with ST-elevation Acute Myocardial Infarction (AMI). Data concerning associations between an elevated glucose level on admission and other in-hospital complications are still limited. A total of 1,137 AMI patients with complete admission blood glucose level (ABGL) analysis were identified and stratified according to ABGL. A total of 16.1% patients had admission glucose level <5 mmol/L, 36.1% <7 mmol/L, 20.2% <9 mmol/L, 9.9% <11 mmol/L and 17.7% ≥11 mmol/L. Compared with the euglycemia group, both the hypo- and hyperglycemia groups were associated with higher in-hospital mortality. In-hospital mortality of diabetic patients with hypoglycemia (12.2%) was higher than that of diabetic patients with either euglycemia or mild hyperglycemia (11.1%, or 10.7% relatively). The same results were seen in non-diabetic patients. In the logistic regression analysis, admission glucose and cardiac function of Killip grade were the independent predictors of in-hospital death for patients with AMI. Elevated admission glucose levels are associated with an increased risk of life-threatening complications in diabetic and non-diabetic AMI patients. Compared with the euglycemia group, hypoglycemia was associated with a higher trend of in-hospital mortality.
