Evidence has been accumulating for a link between Chlamydia pneumoniae and coronary heart disease (CHD). A spreadsheet model was used to estimate the impact of different strategies for screening and treating C. pneumoniae on the incidence of myocardial infarction and cardiac mortality over a 1-year post-intervention period. It was found that screening would potentially be most cost-effective in...

Left ventricular (LV) thrombus is usually seen in situations with reduced LV function, and is mostly seen in patients with large anterior ST-elevation myocardial infarction (MI). Most embolic events, in patients with LV thrombus formation, occur within the first 3-4 months, thus the recommendations regarding the duration of anticoagulant therapy. According to guidelines, an oral vitamin K antag...

OBJECTIVE Electrocardiography (ECG) may be a practical guiding tool for prognostic infarct sizing in ST elevation acute myocardial infarction (STEAMI). In this study, we sought to find a relation between the infarct size and the change in the QRS axis after thrombolytic therapy. MATERIALS AND METHODS Patients with STEAMI who received thrombolytic therapy were selected retrospectively. The mea...

Ventricular free wall rupture is a devastating complication of acute myocardial infarction. It occurs in 15-25% of fatal cases. However, the overall incidence in acute MI cases is about 2%. [1] Clinical markers suggesting free wall rupture include pulseless electrical activity in a first MI, and pericardial tamponade. Subacute rupture takes hours or days to develop, and is suggested clinically ...

Background: The study was taken up to evaluate the left ventricular systolic and diastolic function after acute myocardial infarction (AMI) in male patients. Method: A hospital based study was conducted at tertiary care centre in UP, India with 60 male healthy controls and 125 confirmed cases of AMI admitted to the coronary care unit who fulfilled the inclusion criteria. After a clinical examin...

BACKGROUND Complement, activated during myocardial ischemia and reperfusion, causes myocardial damage through multiple processes. The COMplement inhibition in Myocardial infarction treated with Angioplasty (COMMA) trial was performed to determine the effect of pexelizumab, a C5 complement inhibitor, on infarct size in patients with ST-segment-elevation myocardial infarction (MI) undergoing prim...

Precordial ST-segment mapping was applied serially in the coronary care unit for the study of 46 patients with myocardial infarction (MI), using a 49-lead system. Data from the maps were compared with clinical status of patients, conventional ECGs obtained simultaneously, and serum enzyme levels. Stability of the maps over a one hour period was noted in the early phase of admission. However, a ...

BACKGROUND Myocardial infarction (MI) is rare in children, and Kawasaki disease is now recognized as the main cause for MI. In this report, we present a child with MI caused by myocardial bridge (MB). METHODS A 7.5-year-old boy was admitted to Weifang People's Hospital on September 16, 2008 for heart disease. By electrocardiogram, coronary CT angiography, emission computed tomography, and oth...

Simultaneously recorded standard electrocardiograms (ECG) and Frank vectorcardiograms (VCG) were correlated with the coronary arteriograms and the left ventiiculograms of 210 patients. Quantitative criteria were applied to ECG measurements made by manual technics and to VCG measurements obtained by computer technics. As the extent of significant arteriographic disease increased, the frequency o...

The effect of recanalization of the "infarct vessel" on left ventricular (LV) function was assessed 6-8 weeks after acute myocardial infarction (MI) in two groups: patients who had streptokinase-induced recanalization during the acute phase and control patients who had spontaneous recanalization. The ejection fraction and severity of LV wall motion abnormalities in 100 patients with recanalizat...
