BACKGROUND AND OBJECTIVES: A higher neutrophil to lymphocyte ratio (NLR) has been associated with poor clinical outcomes in various cardiac diseases. However, the clinical availability of NLR in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) has not been known. We evaluated the availability of NLR to predict clinical outcomes in patients with STEMI undergoing primary PCI. SUBJECTS AND METHODS: We analyzed 326 consecutive STEMI patients treated with primary PCI. The patients were divided into tertiles according to NLR: NLR6.53 (n=110). We evaluated the incidence of major adverse cardiac events (MACE), a composite of all causes of death, non-fatal MI, and ischemic stroke at the 12-month follow-up. RESULTS: The high NLR group was associated with a significantly higher rate of 12-month MACE (19.1% vs. 3.7%, p<0.001), 12-month death (18.2% vs. 2.8%, p<0.001), in-hospital MACE (12.7% vs. 2.8%, p=0.010) and in-hospital death (12.7% vs. 1.9%, p=0.003) compared to the low NLR group. In the multivariable model, high NLR was an independent predictor of 12-month MACE {hazard ratio (HR) 3.33 (1.09-10.16), p=0.035} and death {HR 4.10 (1.17-14.46), p=0.028} after adjustment for gender, left ventricular ejection fraction, creatinine clearance, angiographic parameters and factors included in the Thrombolysis in Myocardial Infarction risk score for STEMI. There was a significant gradient of 12-month MACE across the NLR tertiles with a markedly increased MACE hazard in the high NLR group (log rank test p=0.002). CONCLUSION: The NLR is a useful marker to predict 12-month MACE and death in patients with STEMI who have undergone primary PCI.

The incidence of left ventricular aneurysm following acute myocardial infarction is 5 to 10 percent. Eighty % of aneurysms involve the anteroapical wall of the left ventricle: They are four times more frequent in this wall than in the inferior or posterior wall. Anterior myocardial infarction causes aneurysm in the anteroapical wall of the left ventricle, while inferior myocardial infarction causes aneurysm in the posterobasal wall of the left ventricle. Yet the aneurysmal complications in the interventricular septum after myocardial infarction are very rare. A 74-year-old woman with inferior myocardial infarction presented with both an aneurysm of the inferobasal wall and a ventricular septal rupture, and these were detected by two-dimensional and Doppler echocardiography. The aneurysm originated from the inferobasal portion of the left ventricular wall. The short-axis view of the two-dimensional echocardiography revealed an abrupt discontinuity of the junctional area of the inferoseptum and the inferior segment, and a large aneurysm at the inferior portion of the left ventricular cavity. The communication orifice was 4 cm wide. Color Doppler echocardiography showed a left-to-right shunt flow from the aneurysm to the right ventricle. We report here on a case of an aneurysm of the inferobasal wall and a ventricular septal rupture, and these lesions were detected by two-dimensional and Doppler echocardiography.

Intussusception frequently occurs in children as the main causes of intestinal obstruction in childhood but relatively rare in adult. A 65-year-old male visited our hospital because of abrupt onset right lower quadrant pain with tenderness for three days. He had a previous history of appendectomy and alcoholic liver cirrhosis. On physical exam, bowel sound was decreased. Abdomen ultrasonography showed a kidney like mass and abdominal computed tomography revealed the typical target lesion in the ileocecal area. Colonoscopy was performed which failed to find any lesion leading to intussusception. After the colonoscopy, the abdminal pain had disappeared, and we would not find any intussusception sign by abdominal ultrasonography. Colonocopy was done two weeks later. No pathologic lesion was found, then. We report a case of adult idiopathic ileocecal intussusception reduced by colonoscopy.
