Long-term clinical outcome of acute myocardial infarction according to the early revascularization method: a comparison of primary percutaneous coronary interventions and fibrinolysis followed by routine invasive treatment / 영남의대학술지

BACKGROUND: This study was conducted to provide a comparison between the clinical outcomes of primary percutaneous coronary intervention (PCI) and that of fibrinolysis followed by routine invasive treatment in ST elevation myocardial infarction (STEMI).METHODS: A total of 184 consecutive STEMI patients who underwent primary PCI or fibrinolysis followed by a routine invasive therapy were enrolled from 2004 to 2011, and their major adverse cardiovascular events (MACEs) were compared.RESULTS: Among the 184 patients, 146 patients received primary PCI and 38 patients received fibrinolysis. The baseline clinical characteristics were similar between both groups, except for triglyceride level (68.1±66.62 vs. 141.6±154.3 mg/dL, p=0.007) and high density lipoprotein level (44.6±10.3 vs. 39.5±8.1 mg/dL, p=0.005). The initial creatine kinase-MB level was higher in the primary PCI group (71.5±114.2 vs. 35.9±59.9 ng/mL, p=0.010). The proportion of pre-thrombolysis in MI 0 to 2 flow lesions (92.9% vs. 73.0%, p < 0.001) was higher and glycoprotein IIb/IIIa inhibitors were administered more frequently in the primary PCI group. There was no difference in the 12-month clinical outcomes, including all-cause mortality (9.9% vs. 8.8%, p=0.896), cardiac death (7.8% vs. 5.9%, p=0.845), non-fatal MI (1.4% vs. 2.9%, p=0.539), target lesion revascularization (5.7% vs. 2.9%, p=0.517), and stroke (0% vs. 0%). The MACEs free survival rate was similar for both groups (odds ratio, 0.792; 95% confidence interval, 0.317–1.980; p=0.618). The clinical outcome of thrombolysis was not inferior, even when compared with primary PCI performed within 90 minutes.CONCLUSION: Early fibrinolysis with optimal antiplatelet and antithrombotic therapy followed by appropriate invasive procedure would be a comparable alternative to treatment of MI, especially in cases of shorter-symptom-to-door time.

A Case of Gastric Rupture and Pneumoperitoneum after Cardiopulmonary Resuscitation in Acute Myocardial Infarction

Latrogenic gastric rupture is a rarely reported complication of cardiopulmonary resuscitation. Rupture can occur during chest compressions when the stomach is overinflated due to difficult airway management or esophageal intubation. The prognosis of gastric rupture is generally poor, so patients should undergo surgical treatment as soon as possible. We present the case report of a patient with an acute myocardial infarction who experienced gastric perforation and pneumoperitoneum after cardiopulmonary resuscitation.

A case of coronary fistula between the left anterior descending and main pulmonary artery complicating acute myocardial infarction in a 27-year-old man / 대한내과학회지

We report a case of coronary fistula between the left anterior descending and main pulmonary artery complicating acute non-Q wave myocardial infarction. A 27-year-old man visited emergency department because of severe chest pain lasting two hours. The electrocardiogram showed ST segment elevation in precordial leads V3~6. Cardiac enzymes were as follows;CK-MB:36.44 IU/L T-T:0.489 ng/mL, CPK:542 IU/L, and LDH:475 IU/L. The thallium-201 dipyridamole stress perfusion scan showed perfusion defect and reversed redistribution in the anteroseptal wall. The coronary angiogram revealed coronary artery fistula between the proximal left anterior descending artery and main pulmonary artery without significant stenoses of coronary arteries. The result of ergonovine test was negative. After micro-coil embolization to the coronary fistula, symptoms were improved. Follow-up thallium-201 scan showed normalized blood flow in the left anteroseptal wall.

Long or Multiple Stenting in Primary Angioplasty

BACKGROUND: Primary stenting as a direct reperfusion procedure after acute myocardial infarction might reduce recurrent myocardial infarction and target vessel revascularization. However, result of long or multiple stenting in the long or tandem lesions were not known. METHOD: From Jan. 1996 to Dec. 1998, patients with acute myocardial infarction including cardiogenic shock were undergone primary stenting using long or multiple stent. The clinical end points were death, recurrent infarction, subsequent bypass surgery, or repeat angioplasty of the infarct-related vessel. The results were compared with age, sex, lesion, and risk matched standard stenting group. RESULT: Baseline characteristics were similar for the 20 patients who underwent standard length stenting and the 13 patients who underwent long or multiple stenting. Stent diameter was similar in two group (3.4+/-0.3 mm vs. 3.5+/-0.4 mm, p=0.65), but total stent length was longer in long or multiple stenting group (15.5+/-1.8 mm vs. 40.18.4 mm, p=0.01). Average numbers of stent using in multiple stenting were 1.5+/-0.7. Stenting in the infarct-related artery was successful in all patients randomized to stent treatment. At 6 months, the incidence of the primary end point was 25% (5/20) in the standard stent group and 31%(4/13) in the long or multiple stent group (p=0.5). CONCLUSION: Outcomes of long or multiple stenting including mortality, recurrent myocardial infarction and target vessel revascularization was similar to standard stenting. Long or multiple stenting after acute myocardial infarction may possible procedure in some selective cases having long or tandem lesion.

Balloon Angioplasty and Stent-Supported Angioplasty for Acute Myocardial Infarction

BACKGROUND: Although the superior reperfusion and improved clinical outcome following angioplasty for acute myocardial infarction (AMI) have been well known, 10 to 15% of reinfarction and recurrent ischemia in hospital are main limitation of primary percutaneous transluminal coronary angioplasty (PTCA). This study was undertaken to examine the safety and feasibility of stent-supported primary angioplasty in acute myocardial infarction. METHODS: Between July 1995 and Jun. 1997, 32 patients underwent direct or rescue PTCA, including patients with cardiogenic shock. After PTCA, stenting was attempted in patient with dissection or having more than 30% of residual stenosis. Result: In patient with direct PTCA, angiographic success rate was obtained in 91% (30/32). Stenting was attempted in 15 of 30 patients. These patients had suboptimal results (8 patients), non-occlusive dissection (3 patients) and acute occlusion (2 patient). Thrombolysis in myocardial infarction (TIMI) grade 3 flow was restored in 28 patients (93%). In one patient no-reflow phenomena was observed following stent insertion. Despite intra-aortic balloon pumping, there was one death during the hopitalization due to cardiogenic shock following PTCA. Subacute stent thrombosis developed in two patients. 27 patients (90%) were event-free and clinically improved through out the follow up period (11.5+/-5.2 month). Quantitative angiography showed excellent angiographic result after stenting compared with balloon PTCA (2.4+/-0.6 mm vs. 3.4+/-0.3 mm p<0.01). CONCLUSION: After failure of initial angioplasty, coronary stenting can be a supportive therapeutic strategy. Coronary stenting results in a high degree of angiographic success, a low incidence of subacute thrombosis.

A Case of intracranial hemorrhage with polyradiculoneuropathy in Hypereosinophilic Syndrome / 대한내과학회지

Clinical criteria have been established for idiopathic hypereosinophilic syndrome (HES): persistent eosinophilia of 1500 eosinophils/mm3 for at least 6 months or death even within 6 months with signs and symptoms of HES; no evidence for parasitic, allergic, or other recognized causes of eosinophilia despite careful evaluation; and signs and symptoms of organ system involvement or dysfunction, such as congestive heart failure, hepatosplenomegaly, central nerveous system disease. Because cerebral hemorrhage in HES has not been reported yet in Korea, we report a case of hypereosinophilic syndrome with peripheral blood eosinophilia, with biopsies of skin and duodenum showing diffuse eosinophilic infiltration, and multiple organ dysfunction in a 49 year old man died of cerebral hemorrhage three months after the occurrence of the disease.

A Case of Hypertension Secondary to Paraganglioma of the Posterior Mediastinum

Functional paraganglioma of the mediastinum is an uncommon tumor of the paraganglion system that causes symptoms and signs of episodic catecholamine release. It has not been reported in Korea. We experienced a case of a 17 years old man with a history of diaphoresis and paroxysmal hypertension refractory to therapy since 14 years old. Urinary execretion of catecholamine and its metabolites were elevated. Computed tomography(CT) scan revealed high density mass located on the posterior mediastinum in the area of the right fifth intercostal space. At thoracotomy, a 3X3X4cm sized lesion was resected and confirmed as a paraganglioma.

Coronary Intervention of Cardiogenic Shock in Acute Myocardial Infarction

BACKGROUND: Despite improvement of mortality in acute myocardial infarcrtion, high mortality rate associated with cardiogenic shock remains essentially unchanged. We have reviewed our result of coronary intervention in 15 patients and found relative survival advantage. METHODS: Between Sep. 1992 and Aug. 1995, 15 consecutive patients(M. 10, F. 5) with cardiogenic shock in acute myocardial infarction were treated with coronary intervention using ballon PTCA. IABP was inserted in all patients prior to PTCA. RESULTS: 1) Most commonly found infarct related artery was left anterior descending artery(11) followed by right coronary artery(3) and left main coronary artery(1). 2) Successful reperfusion rate was 86.7%(13/15), and in-hospital mortality rate was 26.7%(4/15). 3) In-hospital mortality was higher in elderly patients compared with less than 70yaer old patients(0%(0/11)vs. 75.0%(3/4)(P < 0.05). 4) Mortality rate was lower in single vessel disease than multivessel disease(11.1%(1/9) vs. 50%(3/6) p<0.05). CONCLUSION: Although this study is uncontrolled, the date suggest that urgent coronary intervention for improving coronary perfusion may reduce mortality of acute myocardial infarction complicated by cardiogenic shock, particularly with single vessel disease and young age group.

2 Cases of Aortoiliac Disease Treated with Strecker Stent Followed by Femoro-Femoral Bypass Graft

In the treatment of aortoiliac disease, two methods could be considered. One is percutaneous transluminal angioplasty, and the other is bypass graft. However sometimes two methods could be combined in high risk patients with a lengthy unilateral occlusion of one iliac artery and less extensive obstruction of the contralateral one, since higher risk aortofemoral bypass surgery may be obviated by femoro-femoral bypass graft after percutaneous treatment of the less diseased iliac artery. We report two cases of arortoiliac disease treated with Strecker stent followed by femoro-femoral bypass graft.

On physical findings, hypertension, tachycardia, facial plethora, moon face, buffalo hump and truncal obesity were found.

A Study on Erythrocyte Deformability in Essential Hypertension

BACKGROUND: To pass through the microcirculation, erythrocytes need to undergo considerable deformation. We performed an experiment to investigate the erythrocyte deformability in healthy adults and in patients with uncontrolled hypertension and controlled hypertension. METHODS: 5ml of whole blood is anticoagulated with 2mg ethylenediaminotetra-acetic acid(EDTA). 1ml graduated plastic syringe, without its plunger, is filled with anticoagulated whole blood to the 1ml mark, And the syringe is put into the assembled membrane holder. Under standard condition, whole blood is passed through a 5micro polycarbonate membrane filter under negative pressure of 20cm H2O. The studies are performed at roon temperature and within two hours of venipuncture. RESULTS: Erythrocyte deformability was observed in 91 normal healthy adults and 25 patients with uncontrolled hypertension and 18 patients with controlled hypertension. Following results were obtained. 1) In male control age group I, II, III, the erythrocyte deformability indices were 0.776+/-0.125, 0.792+/-0.189, and 0.714+/-0.172 respectively and in female the indices were 0.880+/-0.138, 0.865+/-0.182 and 0.796+/-0.170 accordingly. 2) THe RBC deformability indices in female control troup were significantly higher than the male group in statistics(p0.05). CONCLUSION: This study reveals that the erythrocyte deformability in patients with essential hypertension is significantly lower than the healthy adults.

A Study on Left Ventricular Mass in Patients with Hypertension

Hypertension is a well known causative factor of congestive heart failure and other cardiovascular disease, and usually induce myocardial hypertrophy. Recent study shows that some antihypertensive drugs may reduce the hypertrophied cardiac mass reversibly. And over the past some decades, increasing attention was focused on these drugs. These drugs include methyldopa, angiotensin converting enzyme inhibitor, calcium channel inhibitor, beta-adrenergic blocker, but diuretics and vasodilators were known not to reduce the hypertrophied ventricular mass. In this study, 46 hypertensive patients were managed by captopril, atenolol, or hydrochlorothiazide monotherapy. And wer estimated and follow up LV mass by echocardiography during 3 months. Captopril and atenolol group showed LV mass reduced, but hydrochlorothiazide group did not. LV mass was reduced more in captopril group than in atenolo group. In conclusion, we have been impressed by this study that diuretics monotherapy for hypertension shoud be reconsidered. And we concluded that drugs which can reduce myocardial mass shoud be chosen to control hypertension as a monotherapeutic drug or a additive drug.

Observation of the Serum Uric Acid in Essential Hypertension

We studied serum uric acid in 120 patients of essential hypertension visiting Department of Internal Medicine of Seoul Red Cross Hospital from October 1985 to November 1986 and analyzed its values in terms of various clinical and laboratory parameters. The results wereas follows; 1) The mean concentration of serum uric acid and incidence of hyperuricemia were 6.5+/-1.86mg%, 50.8% in hypertension group and those of normal control were 3.75+/-1.27mg%, 13.3%, respectively with significant high values in hypertension group. 2) The mean concentration of serum uric acid and the incidence of hyperuricemia were significantly correlated with the levels of diastolic blood pressure but there was only correlation between the incidence of hyperuricemia and the level of systolic pressure. 3) The mean concentration of serum uric acid and the incidence of hyperuricemia were significantly correlated with the level of BUN and serum creatinine, especially more in serum creatinine. 4) The mean concentration of serum uric acid and the incidence of hyperuricemia were not correlated with each level of serum cholesterol and triglyceride. 5) There was significant correlation between mean concentration of serum uric acid and abnormal urine finding but not in incidence of hyperuricemea.

A Study on Changes of Serum HDL-Cholesterol Level in Some Diseases

A study on changes of serum HDL-cholesterol level in various diseased states was performed. Diseased groups were nephrotic syndrome, liver cirrhosis, hyperthyroidism, hypothyroidism and chronic alcoholism. Following results were obtained. 1) Compared to normal control group, levels of HDL-cholesterol in nephrotic syndrome were lower but the difference was significant statistically. 2) In liver cirrhosis, the result showed much lower levels than normal control group with high significance. 3) In both hyper-and hypothyroidism group, the levels of HDL-cholesterol were significantly lower than normal control group. 4) In chronic alcoholism, the levels were significantly higher than normal control group. 5) Except for the group of chronic alcoholism, the levels of HDL- cholesterol were higher in female groups than male groups, but was of no significance statistically.

Effects of Diuretics on Serum and Urinary Electrolytes in Patients with Hypertension

In order to investigate electrolyte changes in serum and urine diuretic therapy, we studied 98 patients with hypertension not optimally controlled by previous treatment. After we divied the patients into three gorups in randomized trial, group A were given Amiloride 10mg/day, group B were given Dihydrochlorothiazide 50mg/day, group C were given Amiloride 5mg/day combined with Dihydrochlorothiazide 25mg/day for 7 days. Blood pressure and electrolyte changes in serum and urine after diuretic theraphy for 7 days were as follows. 1) Serum sodium concentrations were not significantly changed in all three groups(P>0.05). 2) Serum potassium concentrations were increased in group A and C (P<0.05), but there were no significant changes in group B(P<0.05). 3) Urinary sodium exceretions were increased in all three groups(P<0.05). 4) Urinary potassium excretion were decreased in group A and C (P<0.05), but there were increased in group B (P<0.05). 5) Blood pressure were decreased in all three groups(P<0.05).

Effects of Dihydrochlorothiazide, Propranolol, and Prazosin on Serum Lipids in Patients with Essential Hypertension

Three groups of patients with newely diagnosed hypertension, or with hypertension not optimally controlled by previous treatment, completed a comparative study on the effects of Dihydrochlorothiazide, propranolol, and prazosin on plasma lipids after three months therapy. The drugs showed equipotent antihypertensive effects(P<0.01). Dihydrochlorothiazide administration was associated with a significant elevation of total cholesterol(42%, P<0.05), and triglyceride(8.1%, P<0.01). Changes of HDL-C(5.1%), LDL-C(3.3%), and cholesterol ratio(-4.8%) were not significant. Propranolol administration was associated with significant elevation of total cholesterol(3.8%, P<0.05), triglyceride(14.5%, P<0.005), and LDL-C(5.6%, P<0.005). Reduction of HDL-C(-7.8%, P<0.05) and cholesterol ratio(-14.7%, p<0.005) was also statistically significant. Prazosin administration was associated with significant decrease in total cholesterol(-6.6%, P<0.005), triglycride(-9.6%, P<0.005), and LDL-C(-11.7%, P<0.005), and significant elevation of HDL-C(10.6%,P<0.005) and cholesterol ratio(24.2%, P<0.005) was noted.
