Signal-averaged ECG has been used to identify patients at risk for ventricular tachycardia and sudden death after myocardial infarction. The goals of this prospective study were to examine the effects of reperfusion achieved with thrombolytic therapy on the 12-lead signal-averaged ECG and on ventricular arrhythmias in the early period after acute myocardial infarction (AMI). A total of 190 consecutive patients with AMI who fulfilled the inclusion criteria were enrolled. Thrombolysis was attempted in 80 patients and was considered successful in 57 (group I) and unsuccessful in 23 (group II); 110 patients were not treated with thrombolytic agents (group III). Signal averaging of 12 ECG leads was performed within 2 days in all patients and between 7 and 10 days after admission in 163 patients. The filtered QRS complex duration (QRSD) was significantly shorter in group I compared to group III in 7 of 12 ECG leads at 2 days and in 10 of 12 leads at 7 to 10 days. The root mean square voltage of the terminal 40 msec of the QRS complex (RMS40) did not change between the two signal-averaged ECG recordings in group I, whereas it became lower in three ECG leads in group II and in seven ECG leads in group III. There was no correlation between infarct site and significant changes in infarct-related signal-averaged ECG leads. The occurrence of complex ventricular arrhythmias was not significantly different among the three groups. We conclude that successful reperfusion, compared with failed and nonattempted reperfusion, is associated with fewer abnormalities in the 12-lead signal-averaged ECG in the early period after AMI.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

Summary Controversy surrounds the safety of digoxin use in patients recovering from acute myocardial infarction. Previous observations yielded contradictory conclusions. To determine whether digoxin therapy is associated with increased mortality in patients recovering from acute myocardial infarction, we analyzed data from 1731 survivors of acute myocardial infarction enrolled in the Secondary Prevention Reinfarction Israeli Nifedipine Trial (SPRINT), from which patients with severe heart failure were excluded. At the time of hospital discharge, 175 patients (10%) were taking digoxin. Mortality over 1 year after infarction was significantly higher in patients treated with digoxin than in patients who were not receiving digoxin [27 of 175 (15%) vs. 60 of 1556 (4%); p<0.0001]. Digoxin administration was associated with increased mortality in several subsets of patients. Since patients treated with digoxin had baseline characteristics predictive of mortality more frequently than their counterparts, we adjusted for these differences. Multivariate analysis performed by the Cox proportional hazards model identified treatment with digoxin as an independent determinant associated with increased death during the first year after myocardial infarction [relative risk (RR) 2.8; 90% confidence interval (CI) 1.8–4.2]. Subgroup multivariate analysis indicated digoxin as an independent predictor of first year death in 464 patients who developed heart failure during their hospital stay (RR 2.3; 90% CI 1.3–4.0), as well as among 1267 patients who did not (RR 3.4; 90% CI 1.7–6.9). The present study suggests a significant excess mortality associated with digoxin therapy after myocardial infarction. The increased mortality risk may be related to unidentified variables associated with the severity of disease in patients treated with digoxin. However, our findings raise concern that the administration of digoxin may contribute to increased mortality in survivors of acute myocardial infarction. 相似文献

A widened QRS interval is associated with increased mortality in patients with heart failure (HF). However, the prognostic significance of the type of bundle branch block (BBB) pattern in these patients is unclear. The data of 4,102 patients with HF hospitalized during a prospective national survey were analyzed to investigate the association between BBB type and 1-year mortality in 3,737 patients without pacemakers. Right BBB (RBBB) was present in 381 patients (10.2%) and left BBB (LBBB) in 504 patients (13.5%). RBBB and LBBB were associated with increased 1-year mortality on univariate analysis (odds ratio [OR] 1.44, 95% confidence interval [CI] 1.15 to 1.81, and OR 1.20, 95% CI 0.97 to 1.47, respectively). In patients with systolic HF, after adjusting for multiple risk factors, only RBBB was found to be an independent predictor of mortality (RBBB vs no BBB OR 1.62, 95% CI 1.12 to 2.33, and RBBB vs LBBB OR 1.71, 95% CI 1.09 to 2.69). This correlation was stronger in patients with lower left ventricular ejection fractions and was also maintained in patients without acute myocardial infarctions. Analyzing the data for all patients with HF, there was a trend for increased mortality in the RBBB group only (adjusted OR 1.21, 95% CI 0.94 to 1.56). LBBB was not related to mortality in patients with either systolic HF or preserved ejection fractions. In conclusion, RBBB rather than LBBB is an independent predictor of mortality in hospitalized patients with systolic HF. This prognostic marker could be used for risk stratification and the selection of treatment. 相似文献

Introduction and objectives
To present the annual report of the Working Group on Cardiac Catheterization and Interventional Cardiology on the activity data for 2017.Methods
Data were voluntarily provided by Spanish centers with a catheterization laboratory. The information was introduced online and was analyzed by the Steering Committee of the Working Group on Cardiac Catheterization and Interventional Cardiology.Results
In 2017, data were reported by 107 hospitals, of which 82 are public. A total of 154 218 diagnostic procedures (138 448 coronary angiograms) were performed (2.2% increase vs 2016). The use of intracoronary diagnostic techniques significantly increased, especially that of pressure wire (23.2% vs 2016, n = 7003). In 2017, the number of percutaneous coronary interventions rose to 70 928 (3.2% increase), of which 21 395 interventional procedures were performed in the acute myocardial infarction setting. A total of 105 529 stents were implanted, of which 90.3% were drug-eluting stents (6% increase). Radial access was used in 85.7% of diagnostic procedures and in 88.4% of interventional procedures. The number of transcatheter aortic valve implantations continued to increase (28.2% increase, n = 2821), as did the number of left atrial appendage closures (14.8% increase, n = 582) and percutaneous mitral valve repair procedures (14.1% increase, n = 270).Conclusions
Diagnostic and therapeutic procedures in acute myocardial infarction increased in 2017. The use of the radial approach and drug-eluting stents also increased in therapeutic procedures. The number of structural procedures rose significantly compared with previous years. 相似文献106.

We report on a 40 year old woman who presented with typical unstable angina pectoris associated with pulmonary oedema, due to poorly controlled hyperthyroidism. No cardiac abnormality was detected by echo-Doppler and nuclear ventriculography. Coronary angiography demonstrated normal coronary arteries. This case represents a new manifestation of the known association of cardiac ischaemia with hyperthyroidism in the presence of normal coronary arteries. 相似文献

BackgroundThe spleen is a key organ within the immune system. Its removal is known to bring about adverse effects such as an increased susceptibility to overwhelming infection. Few reports have suggested that the spleen may play a role in controlling eosinophilic responses, mostly based on animal models.ObjectivesTo examine whether the human spleen impacts eosinophil numbers in the blood.MethodsWe have retrospectively analyzed eosinophil counts and medical records of 29 patients who had undergone splenectomy between 2000 and 2010. Statistical comparison was performed between post-splenectomy blood counts and both pre-splenectomy and control values. Data regarding the clinical settings around hypereosinophilia events were obtained from patient charts.ResultsAn increased rate of eosinophilia was observed after splenectomy as compared with normal individuals. Furthermore, a considerable proportion of patients who had undergone splenectomies (8/29) presented peak eosinophil numbers exceeding 1,000/mm3, reaching a maximum of 3,070/mm3. These values were mostly encountered perioperatively or during episodes of acute infection.ConclusionsOur data indicate that impaired control of eosinophilic responses is a long-term post-splenectomy effect and is evident in the context of acute stress. We suggest that the spleen plays a significant role in controlling eosinophil levels and that these cells may mediate some of the harmful consequences observed after removal of the spleen. 相似文献
