BACKGROUND AND OBJECTIVES: Acute coronary syndrome occurs most commonly in the setting of atherosclerotic coronary artery disease, but there is little information concerning the mechanism responsible for the transition from stable to unstable coronary atherosclerotic plaque. Hypothetically, several microorganism(Chlamydia pneumonia, Cytomegalovirus and Helicobacter pylori) and their inflammatory reaction have been suggested as a causative motive in progression of acute coronary syndrome. Although it is unclear whether the serum level of CRP as a inflammatory parameter is concerned with previous inflammatory change or myocardial necrosis, CRP apper to be predictive of higher risk for cardiac event in the patients with acute coronary syndrome. Our objective was to evaluate whether the inflammatory parameters(CRP, ESR and WBC count) is useful in predicting the short-term cardiac risk within 30 days. MATERIALS AND METHOD: One hundred and ten patients with acute coronary syndrome were enrolled from April 1998 through August 1998. Blood samples were collected at 1st hour, 24th hour, 48th hour and 7th day and tested for CRP, ESR, WBC count and CK-MB level. Values of 323 normal were used as control. All patients were followed up for 30 days and assessed for the presence of cardiac complications. RESULTS: Peak CRP value of the patients with acute myocardial infarction(3.4+/-3.85 mg/dL, n=2) was higher than that of the patients with unstable angina(0.7+/-0.93 mg/dL, n=8, p<0.05) and controls(0.3+/-0.48 mg/dL, n=23, p<0.05). Peak CRP value of patients with cardiac complication was higher than that of patients without complication(7.7+/-4.77 mg/dL, n=5 vs 1.3+/-1.74 mg/dL, n=5 ; p<0.05). In multivariate analysis, peak CRP value was the only predictive parameter for development of cardiac complications in the patients with acute coronary syndrome(Odds ratio 4.893, 95% confidence interval 1.212-19.756, p value=.026). In the high-CRP group(>2 mg/dL, n=0), the cardiac complication rate was higher than the low-CRP group(< or =2 mg/dL, n=0) (43.3% vs 2.5%, p<0.05). Peak CRP value was correlated with age(r=.191, p=.045), pulse rate(r=.186, p=.008), left ventricular ejection fraction(r=0.384, p<0.001), peak ESR(r=.383, p<0.001) and peak WBC count(r=.307, p=.001), but not with peak CK-MB level. CONCLUSION: Elevated CRP level in patients with acute coronary syndrome seems to be a valuable prognostic factor for the development of cardiac complications within 1 month after admission.

BACKGROUND AND OBJECTIVES: Most reports about coronary angiographic findings in acute myocardial infarction were done after thrombolytic therapy or several days after onset of symptom. The aim of this study is to evaluate coronary angiographic findings in patients with AMI within 24 hours after onset of symptoms and without thrombolytic therapy. Also we evaluated the correlation between the risk factors and severity of coronary artery disease. MATERIALS AND METHODS: We studied 70 patients with acute myocardial infarction admitted to Kyungpook National University Hospital (KNUH) from November 1997 to January 1999, and evaluated the clincial and coronary angiographic findings. We analyzed risk factors of coronary artery disease: age, total cholesterol, tiglyceride, high density lipoprotein (HDL)-cholesterol, low density lipoprotein (LDL)-cholesterol, hypertension, smoking, diabetes and family history of CAD. Coronary angiography was done immediately after the arrival at emergency room (door-to- angiography time). Exclusion criteria were delayed arrival (more than 24 hours after symptom onset), previous history of anticoagulation or medication of antiplatelet agents. RESULTS: 1) Among 70 patients (M/F: 53/17), 59 patients had Q wave myocardial infarction (QMI) (84%), 11 patients had non-Q wave-MI (NQMI) (16%). 2) The mean age was 61+/-12.2 years (range: 26 to 82 years). 3) The mean time from the onset of chest pain to angiography was 6.2+/-4.7 hours. 4) Twenty eight patients (40%) had one-vessel disease, 25 (36%) had two-vessel disease and 17 (24%) had three-vessel disease. 5) The location of infarct related arteries were as follows: LAD in 33 (47%), LCX in 13 (19%) and RCA in 24 (34%). 6) The mean diameter stenosis of infarct related artery (IRA) was 95+/-10.9%. According to the American College of Cardiology/American Heart Association (ACC/AHA) classification of IRA, type B lesion occurred most commonly in 56 patients (80%). 7) Thrombus was observed in 44 patients (63%) with QMI versus 3 patients (27%) with NQMI (p=0.006). 8) Calcifications of the wall of coronary arteries were observed in 28 patients (40%) and correlated with ages of patients. 9) History of cigarette smoking was present in 73%, hypertension in 31% and hypercholesterolemia in 15% of patients. The mean number of risk factor for each patient was 1.3. 10) Multivessel disease was significantly more frequent in patients who had two more risk factors. 11) The frequency of cigarette smoking was greater and the level of plasma triglyceride were higher in patients under 50 years of age. 12) One patient died during coronary angiography and another 2 patients died at 5 and 8 days after coronary angiography due to cardigenic shock. CONCLUSION: In immediate coronary angiographic findings in patients with AMI, multivessel disease and thrombus, and severe stenosis of IRA were observed more frequently than other studies after thrombolytic therapy or after several days of delay. Multivessel disease was significantly more frequent in the patients who had two or more risk factors of atherosclerosis.

BACKGROUND AND OBJECTIVES: The intracoronary stent may be useful in the preventing of abrupt closure and coronary restenosis after coronary angioplasty, and recently primary stenting has been one of therapeutic modalities. We assessed the clinical and angiographic results of primary NIR stenting in patients with acute myocardial infarction (AMI). MATERIALS AND METHODS: Between November 1997 to January 1999, 55 stentings with NIR stents were done in 51 patients with acute myocardial infarction. Angiographic follow-up was available at 7+/-2.3 days in 35 patients. RESULTS: 1) Among 51 patients (M/F: 37/14), 44 patients had Q-wave MI (86%), 7 patients had non-Q-wave MI (14%). 2) The mean age was 61+/-12.4 years (range: 26 to 82 years). 3) The mean time from the onset of chest pain to the arrival at emergency room was 4.6 +/- 4.2 hours. The mean door-to-balloon time was 93+/-46 minutes 4) Treated vessels were as follows: 28 in LAD, 17 in RCA, 10 in LCX. 5) The indications for stent implantation were suboptimal angiographic results after PTCA in 38 lesions (69%), dissection in 9 lesions (16%), abrupt vessel closure in 1 lesion and elective in 7 lesions (13%). 6) Single stent implantation was done in 47 patients. Overlapping stents were done in 4 patients. 7) A procedure related complication occurred in one patient, peri-stent dissection without flow limitation. 8) Full expansion of the stent failed in three lesions with coronary calcifications and the residual stenosis was 35, 40, 50% in each case. In these cases, in-stent thrombus was not demonstrated in follow up angiography. 9) The minimal lumen diameter increased from 0.11+/-0.39 to 2.96+/-0.40 mm. 10) Angiographic follow-up on 38 stents in 35 patients demonstrated in-stent thrombus in 3 stents, in-stent restenosis in 1 stent. But in-stent flow limitations were not found in these 4 cases and TIMI III flow were maintained. Patients with Q-wave MI and coronary thrombus on initial angiography were more prone to subacute thrombosis. CONCLUSION: The NIR stent could be used successfully in primary coronary stenting in acute myocardial infarction. The present study shows relatively low risk of subacute stent thrombosis. The rate of restenosis needs to be confirmed by long term study.
