The Difference

To explore the relationship between the changes of ECG indexes and the prognosis after PCI in patients with acute ST-elevation myocardial infarction (STEMI), and to develop the evaluation method and analyze the advantages and characteristics. 420 patients with acute myocardial infarction (AMI) were admitted to our hospital from March 2017 to April 2020. They were divided into the observation group (ST segment elevation type) with 220 patients and control group (non-ST segment elevation type) with 200 patients according to whether ST segment elevation was or not. ECG was detected before and 1 hour after operation, evaluation of thrombolytic effect, 6-minute walking test and echocardiography were performed 3 months after operation. Compared with the control group, the ECG of the observation group showed St Compared with the control group, the thrombolytic effect of the observation group was significantly improved, and the difference was statistically significant (P < 0.05); compared with the control group, the thrombolysis effect of the observation group was significantly improved, the difference was statistically significant (P < 0.05); ECG index can effectively reflect the recovery of cardiac function after PCI in patients with acute STEMI, and can effectively indicate the improvement of symptoms in patients with AMI, which is worthy of clinical application.

To test the feasibility of a small and simple system for telephonic transmission of 12-lead electrocardiograms (ECGs), 70 patients with acute coronary syndrome admitted to the cardiac care unit (CCU) were included in a feasibility study. The transmission system consisted of a belt with multiple electrodes, which was positioned around the chest. The ECG signal was sent to a call centre via a standard telephone line. In parallel, a standard 12-lead ECG was recorded on site. In a retrospective analysis, each lead of the transmitted ECG was compared with the on-site 12-lead ECG with regard to ST-segment changes and final diagnosis. In all 37 patients with acute ST-elevation myocardial infarction, the diagnosis was correctly established on the basis of telephone-transmitted ECGs. In 96% of limb and 88% of chest leads, ST elevations which were visible in standard ECGs were correctly displayed on telephonically transmitted ECGs. In the remaining 33 patients no false-positive diagnosis was made using transtelephonic ECG analysis. A control group of 31 patients without apparent heart disease showed high concordance between standard ECGs and telephonically transmitted ECGs. Telephonically transmitted 12-lead ECGs interpreted by a hospital-based internist/cardiologist might allow a rapid and accurate diagnosis of ST-elevation myocardial infarction and may increase diagnostic safety for the emergency staff during prehospital decision making and treatment of acute myocardial infarction.

Coronary artery fistulas (CAFs) are described as abnormal communications between a coronary artery and cardiac chambers, or other vascular structures. The two types of CAFs are defined as type I (singular fistula) and type II (microfistulas). Even though various electrocardiographic changes have been previously described in CAF patients, coronary-artery microfistulas causing ST-segment elevation in diverse locations have not been reported. We describe a case report of an adult patient who presented with acute inferior myocardial infarction due to coronary-artery microfistulas. During the hospital stay, the patient re-experienced chest pain, and control electrocardiography revealed ST-segment elevation in the I and AVL leads along with reciprocal ST-segment depression in the inferior precordial leads. Although CAFs are clinically rare, they can have important clinical consequences. Microfistulas should be kept in mind as a cause of ST elevation myocardial infarction in some patients.

Background: One of the most effective and used (in our settings) methods of reperfusion of ST elevation myocardial infarction (STEMI) is administration of streptokinase (SK) infusion. This study was conducted with the aim to compare ST segment resolution between diabetic and non-diabetic patients with ST segment elevation myocardial infarction after thrombolysis by streptokinase. Methods: A total of 100 patients with ST elevation myocardial infarction with or without diabetes mellitus were studied from December 2016 to November 2017. Among these half of patients were diabetic while rests were non-diabetic. Streptokinase was administered to all patients. Resolution (reduction) of elevated ST segment was evaluated after 90 min of streptokinase administration. Results: Failed reperfusion (<30% ST resolution) was significantly higher in diabetic as compared to nondiabetic patients (42% vs. 12%, p <0.001). In hospital complications were more in diabetic patients who has failed reperfusion following streptokinase thrombolysis. Cardiogenic shock occurred in 44% and acute LVF in 30% patients and EF (46.54%) was significantly lower in diabetic patients and higher number of diabetic patients had prolong hospital stay than non-diabetic patients with STEMI. Conclusion: The outcome of thrombolytic therapy is adversely affected by diabetes mellitus in patients with ST-elevation myocardial infarction. Cardiovasc. j. 2019; 11(2): 118-122

Objective: Prominent resolution in the ST segment elevation on electrocardiogram(ECG), thrombolysis at the infarction site restoring perfusion determines the effectiveness of the streptokinase therapy. Hyper- coagulable states and lack of efficacy with streptokinase is seen in diabetics. This study aimed to assess the thrombolytic efficacy of streptokinase in diabetic vs non-diabetics patients. Methods: A cross-sectional study was conducted at Cardiology Department of Allama Iqbal Memorial Teaching Hospital, Sialkot from 1st September 2019 to 30th April, 2020. Total 504 patients of which 185 diabetics and 319 non-diabetic were selected. All the patients presenting with first episode of acute ST- elevation myocardial infarction were thrombolysed with 1.5million units of streptokinase within 12hours from the onset of their typical chest pain symptoms. A complete record of ECG changes was kept before and 90 min after thrombolysis with streptokinase. Chi- square test was applied and p value <0.05 was considered significant. Results: 89.19% diabetic patients had >70% resolution of ST segment changes in comparison to 95.61% non-diabetics. 16.76% of the diabetic patients had increased ST-segment elevation post thrombolysis (P- value 0.001). 8.11% and 10.81% reinfarction rates during hospital stay and at one month post-thrombolysis were recorded in diabetics. Reduced left ventricle Ejection Fraction was seen in 62.16% and 58.62% of the diabetic and non-diabetic patients(P-value<0.005). Conclusion: Comparatively decreased efficacy of streptokinase is seen in diabetic patients with reduced resolution of ST-segment.

Introduction. Some patients with clinical symptoms and signs of acute myocardial and coronary artery occlusion have atypical electrocardiographic presentations - ST elevation myocardial infarction equivalents. Rapid recognition of these patterns is imperative, because the condition requires prompt reperfusion therapy following actual guidelines. De Winter pattern. Diagnostic criteria are: tall, prominent, symmetrical T-waves in the precordial leads, upsloping ST segment depression > 1 mm at the J-point in the precordial leads, absence of ST elevation in the precordial leads, ST segment elevation (0.5 mm - 1 mm) in aVR. ST Elevation in aVR. Electrocardiographic criteria include ST segment elevation in aVR ? 1 mm, ST segment elevation in aVR ? V1, and diffuse ST segment depression in lateral leads. Wellens syndrome. Wellens syndrome describes deeply inverted or bi?phasic T-waves in leads V2 - V3, highly specific for significant stenosis of the left anterior descending artery. Posterior infarction. Posterior infarction is confirmed with ST segment depression ? 0,5 mm in leads V1 - 3 and ST segment elevation ? 0.5 mm in posterior leads (V7 - V9). Conclusion. There are many electrocardiographic patterns that physicians should promptly recognize as clinical myocardial infarction with ST segment elevation equivalents in order to perform urgent reperfusion therapy for better prognosis and survival in these patients.

Electrocardiographic Findings

AbstractElectrocardiographic changes resulting from apical hypertrophic cardiomyopathy may mimic an acute coronary syndrome. A 67-year-old Sudanese male without cardiac risk factors presented to hospital with chest pain and electrocardiographic findings of septal ST-segment elevation, ST-segment depression in V4-V6, and diffuse T-wave inversion. He was treated as an acute ST-elevation myocardial infarction with thrombolytics. There was no cardiac biomarker rise and coronary angiography did not reveal evidence of significant coronary arterial disease. Ventriculography, transthoracic echocardiography, and cardiac magnetic resonance imaging were consistent with apical hypertrophic cardiomyopathy. The patient was discharged three days later with outpatient cardiology follow-up. We highlight the clinical and electrocardiographic findings of apical hypertrophic cardiomyopathy, with an emphasis on distinguishing this from acute myocardial infarction.
