BACKGROUND: The major risk factors such as hypercholesterolemia, hypertension, diabetes melitus and cigarrete smoking have not been studied in an attempt to provide a composition of major risk factors in Korea. Also we have met with some patients without major risk factors. METHODS: A Retrospective Study was done on 160 patients of acute myocardial infarction who had been admitted to National Medical Center within 48 hours from onset, from January 1948 to December 1992 and studied on major risk factors of acute myocardial infarction. RESULTS: 1) Among major risk factors, smoking was found in 50%, hypertension in 49%, diabetes in 25% and hypercholesterolemia in 21%. 2) The percentage of patients without major risk factors was 19%. 3) Among major risk factors, hypertension, hypercholesterolemia and diabetes were increasing tendencies, recentely. CONCLUSION: Some patients with acute myocardial infarction don't have any major risk factors. Also hypertension, hypercholesterolemia and diabetes were increasing tendencies. So further study for other risk factors is needed and preventive management should require a commitment to behavior modification and alteration in life-style.

In order to evaluate the accuracy of endoscopic findings in the diagnosis of gastric can the endoscopic findings of gastric lesion were compared with the macroscopic and pathologic findings of excised identical lesion. 105 operated gastric cancer paitients (advanced cancer 95 cases, early cancer 10 cases) who were diagnosed endoscopically at Pusan National University Hospital from January 1983 to August 1987 were studied. The results were as follows; 1) The accuracy of endoscopic findings were 94.7% in the advanced gastric cancer, and 45.5% in the early gastric cancer. 2) The accuracy of gross findings endoscopic and pathologic in advanced gastric cancer were 50.0% in Borrmann type I, 45.0% in Borrmann type II, 73.2% in Borrmann type III, and 66.7% in Borrmann tyye IV. 3) The accuracy of the endoscopy ia morphologic classification of advanced gastric cancer according to pathologic tumor location were 60.0% in C (upper 1/3), 43.9% in M(middle 1/3),76.3% in A (lower 1/3), 55.6% in the anterior wall, 50.0% in the posterior wall, 66.7% in the greater curavature, and 67.2% in the lesser curvature. 4) The accuracy of endoacopy in morphologic classification of gastric cancer to tumor size ware 54.5% in below 2 cm, 54.5% in from 2.1 cm to 4 cm, 65.4% in from 4.1 cm to 6.0 cm, 80% in from 6.1 cm to 8 cm, 75.0% in above 8.1 cm. 5) The accuracy of endoscopy in the morphologic classification according to the pathologic tumor stage in advanced gastric cancer were 55.6% in TNM stage I, 52.0% in TNM stage II, 65.4% in TNM stage III, and 73,7% in TNM stage IV.

BACKGROUND: In pregnant woman, the respiratory system is influenced by the hormonal environment and an enlarged gravid uterus. After delivery of the fetus, and contraction of the uterus, changes in the respiratory system produced by the mechanical effect of the gravid uterus may decrease or be reversed. We designed this study to observe changes in the respiratory mechanics in pregnant woman under general anesthesia for cesarean section. METHODS: 15 pregnant women at term, ASA 1 were studied. Induction was performed with thiopental/succinylcholine and maintained with O2, N2O and enflurane until delivery. Just before delivery, enflurane was discontinued. Vecuronium was given at 0.1 mg/kg iv 4 min after induction, and after delivery, 1 mg was given as needed. Inspired tidal volume, expired tidal volume, inspired minute ventilation, expired minute ventilation, airway peak pressure, plateau pressure, expired volume during the first 1 second/expired tidal volume (V1.0), dynamic compliance and end-tidal CO2 were continuously measured just after induction, at delivery and 5, 10, 15, 20, 25, 30, 40 and 50 min after delivery. Blood pressure, heart rate and oxygen saturation were also measured. RESULTS: Compared to the value after induction, values after delivery showed no significant changes in inspired tidal volume or minute volume, but significantly increased in expired tidal volume and minute volume and dynamic compliance, and a significant decrease in airway peak pressure, plateau pressure, V1.0 and end-tidal CO2. Blood pressure and heart rate increased significantly after induction, compared to before induction. Oxygen saturation was maintained at 99-100%. CONCLUSIONS: After delivery, the effects of the gravid uterus on the respiratory system rapidly disappeared, in particular changes of pressure in the airway preceded the respiratory volume changes.

Isolated left main coronary ostial stenosis is a very rare condition. In the majority of cases there are coexisting diseases in multiple coronary vessels. Here, a case of isolated left main coronary ostial stenosis due to an acute angle take-off, with clockwise rotation of the coronary sinus, confirmed by cardiac MRI is presented. A 44-year old female patient presented with an exertional and stabbing anterior chest pain. The patient had no premedical history. A coronary angiogram showed an isolated left main coronary ostial stenosis due to an acute take-off of the left main coronary artery. A cardiac MRI showed an acute angle take-off of the left main coronary artery, with clockwise rotation of the coronary sinus. The patient underwent surgical angioplasty of the coronary ostia, with a patch of autologous pericardium. This acute angle take-off may be due to rotation of the coronary sinus.
