Mallory-Weiss Tear After Cardiopulmonary Resuscitation in a Patient Suffering From Acute Myocardial Infarction / 고신대학교의과대학학술지

A report of a 79 year old male patient suffering from acute myocardial infarction with Mallory-Weiss tear after successful cardiopulmonary resuscitation(CPR) by emergency medical technician in the swimming pool is presented. Successful percutaneous coronary intervention(PCI) was done after appropriate transfusion. The patient survived and discharged without major complications after admitting 11days in the hospital. Importance of CPR in AMI patient is reiterated as complication such as Mallory-Weiss tear may arise.

The usefulness of cardiovascular MR in prediction of wall motion recovery after revascularization in acute myocardial infarction / 대한내과학회지

BACKGROUND: Cardiovascular MR has recently been reported that it can determine the viable myocardium. We investigated this study to determine the usefulness of cardiovascular MR in prediction of wall motion recovery after revascularization in acute myocardial infarction METHODS: Both cardiovascular MR with contrast enhancement and coronary angiogram were performed in 19 patients with acute myocardial infarction who treated with precutaneous intervention or thrombolytic therapy. Six months follow-up angiogram and MR study were also preformed. Thirty two matched segments model of the left ventricle were used to analysis the wall motion change and the grade of transmural extent of hyperenhancement (TEI). RESULTS: Among 628 segments, 177 segments showed wall motion abnormality. In group of segments showing hypokinesia (68 segments), the proportion of segments showing wall motion improvement was not different from that of the akinetic segments group (109 segments) (50% vs 41.3%, p=0.26). The proportion of segments showing wall motion improvement were 60.5% in group of TEI grade 0, 58.9% in TEI grade I, 51.2% in TEI grade III, 29.4% in TEI grade IV, 8% in TEI grade V. If the groups were divided into two according to cut-off value of TEI 50%, In the group of TEI less than 50%, 67 out of 118 segments (56.8%) showed wall motion improvement in contrast with 12 out of 59 segments (20.3%) in the group of TEI above 50% (p<0.001). The status of baseline wall motion abnormality (hypokinesia or akinesia) did not effect on wall motion improvement after revascularization. CONCLUSIONS: The baseline wall motion abnormality (hypokinesia or akinesia) did not predict the wall motion improvement. But, TEI grade was significant factor to predict the wall motion improvement.

The Meaning of Pathologic Q wave in Myocardial Infarction Assessed by Magnetic Resonance Imaging

BACKGROUND AND OBJECTIVES: The pathologic Q wave was once considered to be a sign of transmural myocardial infarction (MI), but the exact meaning of the pathologic Q wave remains to be elucidated. To evaluate the meaning of the pathologic Q wave using magnetic resonance imaging (MRI) investigations, which has recently emerged as a state-of-the-art diagnostic modality within cardiology. SUBJECTS AND METHODS: Thirty eight consecutive patients with acute myocardial infarction were enrolled in this study. MRI and coronary angiography were performed in all patients during their admission. A 32 segment model was used to analyze the MRI findings. Just before MRI, the electrocardiograms of all the patients were checked and the presence of the pathologic Q wave evaluated. The ischemic territories in each patient were quantified by the number of dysfunctional segments. Myocardial necrosis was determined by the area of delayed hyperenhancement in contrast enhanced MRI, and the myocardial necrosis index per segment was defined as the ratio of the hyperenhanced area to that of the entire segment. The total necrosis index was defined as the sum of all the myocardial necrosis indices in a patient, and the average necrosis index of dysfunctional segment (ANI) was calculated from the total necrosis index/number of dysfunctional segments in a patient. The transmurality of infarction was also assessed. RESULTS: Of all 38 patients, 26 showed a pathologic Q wave on ECG (Group A), whereas the other 12 did not (Group B). The number of dysfunctional segments, total necrosis index and frequency of transmural infarction (defined by infarct transmurality> or = 75% of wall thickness) were no different between the two groups. The infarct transmurality over 25 or 50% and ANI were significantly different between the two groups. In a multivariate analysis, an infarct transmurality over 50% and ANI were significant factors in determining the presence of a pathologic Q wave. CONCLUSION: By an in vivo analysis of myocardial necrosis, as determined by MRI in acute myocardial infarction, an infarct transmurality over 50% and average necrosis index of dysfunctional segments (ANI) might be significant factors in the genesis of a pathologic Q wave.

A Case of IgA Nephropathy Associated with Kimura's Disease / 대한내과학회지

Kimura's disease is a granulomatous disease which develops in the skin, subcutaneous tissues and lymph nodes and which is characterized histologically by the presence of lymphoid follicles, vascular proliferation and infiltration with eosinophils. This disease is mostly confined to the Far East. The frequency of renal involvement in association with this disease is apparently high. But there wasn't any case report of IgA nephropathy associated with Kimura's disease. We report a case of IgA nephropathy associated with Kimura's disease with a review of the literature.
