Efficacy of the percutaneous transluminal coronary recannalization (PTCR) therapy was evaluated by weighting infarct-related coronary artery segments in 28 consecutive patients with acute myocardial infarction. The study focused on the influences of the time interval from the onset of chest pain to PTCR (PTCR-Time) and on the post-infarct left ventricular regional wall motion in conjunction with the serum levels of GOT, LDH and CPK and with PTCR-Time. PTCR success rate was 84.0%, and re-occlusion rate was 4.0%. The thrombolysis in myocardial infarction grade 2, however, was observed in 7 (33.3%) of 21 cases with successful PTCR. There was no significant difference in PTCR-Time between the PTCR success and nonsuccess groups. Significant correlations were observed between the PTCR-Time and each peak value of standardized serum levels of LDH and CPK, and between the PTCR-Time and the post-infarct regional wall motion abnormality. There were also significant correlations between the standardized serum level of each of these three enzymes and the post-infarct regional wall motion abnormality. It was clearly demonstrated that the earlier the recannalization of the infarcted artery was achieved, the less extensive the myocardial damage in quantitative and qualitative aspects.

Aim of our study was to investigate the pathophysiological role of vasoactive intestinal peptide (VIP) in the neuroendocrine activation occurring in acute myocardial infarction (AMI). Plasma VIP concentration has been assayed in 30 patients with AMI, 22 males and 8 females, aged 41-82 years, without other important diseases. VIP plasma values, assayed on admission to the Coronary Care Unit, within 4-6 hours after the onset of chest pain, everyday for the first week and on day 14, were significantly higher in survivors and in patients aged < 60 years. VIP plasma concentration was not statistically correlated with CPK and CPK-MB. VIP seems to play a pathophysiological role in the neuroendocrine activation occurring in AMI. Low VIP plasma levels are associated with an unfavorable short-term prognosis. Moreover, it appears that VIP secretion is negatively influenced by aging.

Although ultrafast computed tomography (UFCT) is able to determine coronary artery bypass graft (CABG) patency, the clinical applicability in the early postoperative period has not been investigated. We prospectively studied 22 consecutive patients who developed angina-like chest pain, electrocardiogram (EKG) abnormalities, elevated creatine phosphokinase-MB fractions (CPK-MB fractions) (> 5%), or sudden cardiac death in the early post-CABG period. UFCT (flow mode) examinations from 4 to 28 days postoperatively were performed at six levels with 13 scans each. Indications for obtaining UFCT included chest pain (14), elevated CPK-MB (14), EKG abnormalities (10), and aborted sudden cardiac death (1). There were 78 grafts evaluated with 87 distal anastomoses. Sixty were saphenous vein grafts (SVG), 16 were left internal mammary artery (LIMA) grafts, 1 was a free right internal mammary artery (RIMA), and 1 was a right gastroepiploic artery. The 60 SVG included 9 sequential grafts with 18 distal anastomoses. UFCT identified 5 occluded nonsequential SVG and of these, 3 underwent coronary angiography confirming the UFCT findings. Visualization was inadequate to determine patency in 5/17 internal mammary artery (IMA) grafts, and all 5 were in the early part of this study and felt to be related to UFCT image protocol. All sequential grafts were determined to be patent on UFCT, although visualization was inadequate to determine if one or both of the outflow distal anastomoses were patent. Our series shows early nonsequential SVG occlusion at 5/51 (9.8%) in patients with postoperative clinical signs of possible graft occlusion. UFCT to determine the patency of proximal grafts is feasible in the early postoperative period. If UFCT is indeed a valid test for graft patency, then this study implies that most signs and symptoms of ischemia in the early postoperative period may not represent graft occlusion.

A 55-year-old female afflicted with mitral valve stenosis and atrial fibrillation was admitted to our hospital complaining of chest pain, ST elevation of ECG (V2-5) and elevated CPK value were recognized. She was diagnosed as having acute myocardial infarction, and percutaneous transluminal coronary recanalization was performed immediately. The coronary angiogram showed occlusion by the thrombus at the proximal left anterior descending branch (#7), even, left ventriculogram showed ventricular aneurysm on the anterior wall. But these lesions could not be recanalized by 960,000 IU urokinase administration. She underwent aneurysmectomy and mitral valve replacement with 27 mm SJM prosthesis. When mitral valve stenosis accompanied with left ventricular aneurysm we considered in order to improve left ventricular function, it is necessary to undergo not only mitral valve operation but left ventricular aneurysmectomy aggressively.

Eighteen patients of 'Q' wave acute myocardial infarction (AMI) (age 50 +/- 6.2 years), underwent dobutamine stress echocardiography (DSE) before hospital discharge (7.2 +/- 1.3 days after AMI) to find out the correlation between response of infarct zone to dobutamine infusion and TIMI grade flow in infarct related artery (IRA). The aim of study was to test the hypothesis that infarct zone which shows improvement in contractility after dobutamine infusion has viable myocardial tissue and would have good flow (TIMI II or III) in IRA. Echocardiographically, improvement in contractility in the centre of infarct zone by at least 1 grade (on a scale of 4) was termed as positive response on DSE. The mean dose of dobutamine was 19.4 micrograms/kg/min. Ten patients had positive response on DSE; 8 of them had good antegrade flow in IRA. Eight patients had no improvement in contractility of infarct zone on DSE; 6 of them had poor flow in IRA. Clinical markers of reperfusion (relief of chest pain, early ST settlement, peak CPK-MB levels), age of patient, site of AMI, time to thrombolysis, resting left ventricular ejection fraction, wall motion score of the infarct zone and presence of collaterals were not significantly different in patients with good or poor flow in IRA. Thus, improvement in contractility of infarct zone after dobutamine infusion can predict good flow (TIMI II or III) in IRA with 80 percent sensitivity, 75 percent specificity, 80 percent diagnostic accuracy, 80 percent positive predictive value and 75 percent negative predictive value.

A 37-year-old woman was taken to a hospital because of sudden chest pain. She lapsed into shock, and the ECG indicated acute myocardial infarction. The ECG later showed ventricular fibrillation, and the patient was given cardiac massage while being transported to our hospital, where she was resuscitated with a percutaneous cardiopulmonary support system. Emergency coronary angiography revealed 99% stenosis of the left main coronary artery. PTCA was performed, and the stenotic lesion was released, but dissection and rapid formation of a thrombus were detected in the LAD. Re-PTCA was performed, but the hemodynamics did not improve, and emergency CABG of the LAD, D1, and LCx was performed. Postoperative max CPK was 18,957 IU/L. Although postoperative MRSA pneumonia developed as a complication, weaning from the respirator was performed 17 days after the operation. The patient was discharged, ambulatory, 74 days after the operation.

This paper is a review of the patients with pulmonary thromboembolism hospitalized at General hospital in Teanj starting from the first case recorded in 1980 till now and 172 patients were subjects of this study. Thromboembolism was a direct cause of death in 43.7% (75 patients). Clinical and laboratory records, etiology, chest radiography, ECG data of 89 patients hospitalised and treated in the last five years were analyzed in detail. The most frequent symptoms were dyspnea and tachypnea, often accompanied with other symptoms (84.2%), chest pain (65.2%), cough (52.4%), tachycardia (40.5%), hemoptysis (25.8%). At 74% of patients with pulmonary thromboembolism a significant simultaneous increase of all examined enzymes, except CPK was found. Pulmonary insufficiency (global or partial) was found at 75% of patients. According to our results, in 57.2% of the subjects the pathologic changes on Radiography (infiltrates of the lung, with or without affection of the pleura and changed position of diaphragm) were found, and 70.9% had changes on the ECG.

Acute lung embolism is an uncommon but recognised complication of deep venous thrombosis. The parameters RTG, ECG, PaO2, PaCO2, LDH, CPK, SGOT, SGPT and pulmonary ventilation/perfusion scan have been examined in 200 patients with pulmonary thromboembolism. For that purpose discrimination values of synopticly relevant RTG findings, arterial blood gas and enzymes analysis results and pulmonary ventilation/perfusion scintigraphy, were observed in a comparative analysis of numerous data that could be integrated as an unique finding in sense of qualitative diagnosis. The most frequent symptom was dyspnea and tachypnea, often accompanied with other symptoms (84%), chest pain (65%), cough (53%), tachycardia (41%), hemoptysis (26%). In 74% of patients pulmonary thromboembolism the significant simultaneous increase of all the mentioned enzymes, except CPK, was found 75%. However, according to the results in 58% of the examined persons the pathologic changes on RTG (infiltrates of the lung, with or without affection of the pleura and changed position of diaphragma) were found, and 71% on ECG. Pulmonary ventilation/perfusion scintigraphy is the precise examination for acute lung embolia. For the routine clinical examination measurement of PaO2, PaCO2, LDH, ECG, x-rays is sufficient (correlation test + 0.56). In this paper we have presented our own diagnostic-therapeutic protocol in of lung emboly.

We report a rare case of idiopathic thrombocytopenic purpura (ITP) associated with acute myocardial infarction (AMI). A 72-year-old woman with hypertension and hemorrhoids was admitted because of chest pain, severe anemia (RBC 340 x 10(4)/microliter, Hb 5.4 g/dl, Ht 21.7%) and thrombocytopenia (0.2 x 10(4)/microliter). AMI was diagnosed by electrocardiogram (ST elevation and negative T in V2-5), echocardiogram (hypokinesis in anteroseptal wall) and laboratory (CPK 470 U/l) findings and was treated with only blood transfusion. Chest pain disappeared the day after admission, and neither heart failure nor arrhythmia occurred. Based on bone marrow findings (hyperplasia of erythroblast and megakaryocyte), endoscopic (internal hemorrhoids) and laboratory (antiplatelet antibody positive, platelet associated IgG 257.8 ng/10(7) cells) findings, iron deficiency anemia and ITP were diagnosed. Anemia improved after blood transfusion, but thrombocytopenia (< 1.0 x 10(4)/microliter) without active bleeding continued after steroid and gamma-globulin therapy. At discharge, electrocardiogram showed a negative T in I, aVL and V2-5, and T1 and BMIPP myocardial scintigram showed defects in the anteroseptal and apical wall.

Prehospital triage of cardiac patients for bypass from community hospitals to cardiac centers may improve survival. This article determines if electrocardiogram (ECG)-based scoring triage methods (Aldrich MI scoring, QRS distortion, and the TIMI classification) and location of infarct (via 12 lead ECG) are associated with mortality before and after adjusting for age, sex, and race. It is a retrospective study of 291 AMI adult patients transported by ambulance to community hospitals or cardiac centers. Patients with an ED chief complaint of chest pain or dyspnea, presence of MI as defined by ECG findings of 0.1 mV of ST segment elevation in two leads or positive CPK-MB were eligible for the study. The primary outcome variable was 2-year mortality as determined with a metropolitan Detroit tri-county death index. Logistic regression was used to calculate the unadjusted and adjusted odds ratios (with 95% CIs) of the predictor variables with mortality. Of the initial population selected for the study (n = 291), 229 patients were eligible for the analysis. The mean age was 66 years (SD of 14.4) with 63.8% being male and 54% being white. The overall mortality point estimate was 21.3% (95% CI of 15.2 to 27.3%). Aldrich scores and QRS distortion (yes/no) were not associated with mortality. Patients classified as a "high risk" for AMI per TIMI status were almost 3 times more likely to die than those at "low risk" and reached borderline statistical significance (P = .06) after adjusting for the covariates. Having an anterior infarct, as opposed to an inferior infarct, was significantly associated with death before and after adjusting for the covariates (Unadjusted OR = 2.6, Adjusted OR = 2.8). Properly training emergency medical system professionals in this area may prove useful for identifying higher risk AMI patients in the prehospital setting.
