OBJECTIVES: We investigated the effects of changes in obesity and life style factors, such as cigarette smoking, alcohol drinking, and exercise, on the changes in blood pressure and serum cholesterol among Korean men. METHODS: This study included 7,205 healthy male employees in the steel manufacturing industry. Each subject underwent health examination in 1994 and was re-examined in 1997. The study subjects were classified into four categories, according to changes in body mass index (BMI) (loss; stable; mild gain; severe gain), cigarette smoking (quitter; non-smoker; smoker continued; smoker started), alcohol drinking (quitter; non-drinker; drinker continued; drinker started) and exercise (more exercise; continuous regular exercise; continuous irregular or no exercise; less exercise), respectively. We evaluated the relationship between the categories of change in those independent variables and the changes in blood pressure and serum cholesterol, adjusted for BMI in 1994 and age by analysis of variance. RESULTS: The change in systolic blood pressure was positively associated with the changes in BMI (p<0.001) and drinking (p=0.001), but negatively with smoking (p=0.004), compared to the first category of each independent variables. The systolic blood pressure was significantly less increased in the continuous smoking group than quitter or non-smoker. The changes in diastolic blood pressure and serum cholesterol appeared to have statistically significant linear relationships only with the change in BMI. The change in exercise showed a marginal significance with diastolic blood pressure (p=0.088). CONCLUSIONS: These prospective data emphasize the importance of obesity as a determinant of the changes in blood pressure and serum cholesterol. In addition, the changes in smoking and drinking habits can affect systolic blood pressure.

Serum lipids and lipoproteins were determined in 70 patients with hypertension, 40 patients with cerebral infarctions, and 41 patients with cerebral hemorrhage. The results were compared with findings in 64 healthy controls. The results are as follows; 1) Total cholesterol, VLDL-cholesterol, LDL cholesterol and total cholesterol/HDL-cholesterol ratio were significantly higher in patients with hypertension or cerebral infarction than in control group, but HDL-cholesterol showed no significant difference. 2) In Patients with cerebral hemorrhage, total cholesterol, LDL-cholesterol and HDL-cholesterol were higher than in normal controls. Total cholesterol/HDL-cholesterol ratio was within the limits of normal. It is possible that the susceptibility to cerebral infarction is the result of high total cholesterol/HDL cholesterol ratio rather than low HDL cholesterol. But our study suggests that hyperlipoproteinemia plays a minor role in the development of cerebral hemorrhage.

BACKGROUND: The cardiac troponin I (cTnI), one of the subunits of the troponin regulatory complex, binds to actin and inhibits interactions between actin and myosin. cTnI is highly sensitive and specific marker for myocardial injury and is useful in diagnosis and detection of reperfusion in acute myocardial infarction (AMI). In this study, we measured the serum concentration of cTnI according to serial time after chest pain in patients with AMI and compared serum concentration of cTnI with CK-MB and echocardiographic data to evaluate the significance of measuring serum concentration of cTnI in AMI. SUBJECTS AND METHODS: The study was carried out on 16 patients with first attack of AMI within 6 hours of chest pain. All patients were performed thrombolytic therapy and reperfusion was confirmed by coronary angiography. Blood samples for measuring of CK-MB and cTnI were collected at 4-h intervals during the first 24 h, 12-h intervals until 48 h, and 24-h intervals until fourth days after hospitalization. Echocardiography were performed before thrombolytic therapy in all patients. RESULTS: 1) The mean age of subjects was 63.6+/-11.5 years (range:44 - 84 years) and 11 patients were men and 5 patients were women. The site of infarction was anterior in 11 patients and inferior in 5 patients. 2) The peak concentrations of CK-MB and cTnI were reached from 4-h to 12-h after admission in all patients (7.3+/-2.6-h, and 9.0+/-3.1-h, respectively), but there was no significant difference in peak time. 3) Serum concentration of CK-MB was normalized at 72-h after admission, but cTnI was remained in increased state until 96-h after admission. The numbers of the patients with above cutoff value of CK-MB and cTnI at different time after admission were significantly different after 72-h (p<0.05). 4) The peak cTnI and sigma cTnI level were significantly correlated with peak CK-MB and sigma CK-MB level, respectively (r 2 =0.7955, p<0.0001 and r 2 =0.6378, p=0.0002, respectively). 5) The ejection fraction was not correlated with peak cTnI concentration (r 2 =0.0948, p=0.2461) and sigma cTnI (r 2 =0.1867, p=0.0946). 6) The wall motion score index was not correlated with peak cTnI concentration (r 2 =0.2135, p=0.0716), but significantly correlated with sigma cTnI (r 2 =0.2540, p=0.0465). CONCLUSION: The serum concentration of cTnI was useful in late diagnosis of AMI and cTnI release in patients with AMI was correlated with myocardial infarct size.

BACKGROUND: Single pass lead VDD pacing preserves atrioventricular synchrony with a single lead system which incorporates floating atrial electrodes. The objectives of this study were to measure whether different body postures and physical activities cause significant changes of the atrial electrogram amplitudes and to evaluate the effectiveness of its atrial sensing, ventricular sensing and pacing. METHOD: Prospective study was done in 7 patients with high degree AV block and normal sinus node function in whom a single lead VDD pacing system was implanted. The P wave amplitude was been measured in different condition during follow-up period. RESULTS: 1) During follow-up period, the P wave amplitude showed variation with changes in posture and respiration, but there was no consistent increase or decrease in amplitude. The lowest P wave amplitude was above the minimal atrial sensing value of 0.2 mV. 2) The percentage of atrial synchronous ventricular pacing recorded in Holter ECG and during Treadmill exercise test was more than 99%. 3) Atrial oversensing or VA cross sensing were not observed in any of the patients. CONCLUSIONS: Despite floating atrial electrode, the single pass lead VDD pacing maintains reliable atrial sensing and ventricular pacing in different body position and physical activity, so it may offer an excellent alternative in patients with high grade AV block and intact sinus node function.

BACKGROUND: The electrocardiogram may provide valuable information regarding the identity of the culprit coronary artery and the location of obstructing lesion within the artery, which may be of guidance in selecting the therapeutic modality. Previous studies have concluded that changes in lateral leads (I, aVL, V5, V6) are predictive of left circumflex coronary artery obstruction in inferior wall acute myocardial infarction. Elect-rocardiographic criteria for determining the location of the obstructing lesion, however, have not been well established. The purpose of this study is to investigate the patterns of ST segment depression in lateral leads in inferior wall acute myocardial infarction and the obstruction site of culprit artery according to ST segment depression in lateral leads. METHODS: We examined 78 patients with inferior wall acute myocardial infarction analizing their electrocardiogram and coronary angiography which performed during acute hospitalization. RESULTS: Of the fifty-five patients in which the culprit artery could be determined, 1)in 41 the culprit artery was the right coronary artery (19 proximal to the right ventricular branch and 22 distal), and in 14 the left circumflex coronary artery (7 proximal to the first obtuse marginal branch or involving a high first obtuse marginal branch, and 7 with distal obstruction). 2)Significant ST depression (ST< or =1 mm) in leads I and aVL was more common in right coronary artery obstruction (p<0.05 and p=0.01 respectively) than left circumflex artery. 3)It was difficult to define the location of obstruction with ST segment change of lateral precordial leads (V5, V6). CONCLUSIONS: In acute inferior wall myocardial infarction, ST segment depression in lateral limb leads (I, aVL) can be indicative of the right coronary artery obstruction and the ST segment depression pattern in lateral precordial leads was not indicative of the site of obstruction.
