To the Editor: In a recent Case Report (1) the abnormal electrocardiographic findings were not confirmed by the enzyme changes as is usually the case in documented myocardial infarction. We would like to point out that some work has been done indicating that serum zinc concentrations decline rapidly after a myocardial infarct (2, 3). After four days the concentration gradually increased to with...

Because of its dynamic nature, the composition and structure of the myocardial collagen network can be reversibly modified to adapt to transient cardiac injuries. In response to persistent injury, however, irreversible, maladaptive changes of the network occur leading to fibrosis, mostly characterized by the excessive interstitial and perivascular deposition of collagen types I and III fibers. ...

OBJECTIVE Chest pain in children and adolescents is a frequent cause for office or emergency department visits. However, it is unclear whether myocardial infarction occurs in children with no anatomic abnormality presenting with chest pain. METHODS Clinical history, electrocardiography, echocardiography, and cardiac enzyme levels were evaluated in patients presenting to the emergency departme...

The 4-ACGC isolated from BP was prepared to investigate the cardioprotective effects on attenuating chronic heart failure in vivo and in vitro. A chronic heart failure (CHF) rat model was established to investigate the cardioprotective effects of 4-ACGC. From this, several cardiac function indexes were recorded. The inflammatory markers including tumor necrosis factor-α (TNF-α), Interleukin-6 (...

Introduction: The aim of the present study was to evaluate the effect of exercise training and L-arginine supplementation on oxidative stress and systolic ventricular function in rats with myocardial infarction (MI). Methods: Four weeks after the surgically-induced MI, 40 male Wistar rats were randomly assigned to the following 4 groups (n=10): MI-sedentary control (Sed) MI-exercise (Ex) MI-...

conclusion osem3d may provide better image quality and higher contrast than other methods for small animal imaging with the new myocardial imaging agent, [18f] fptp. results the location and size of myocardial infarction on pet images correlated closely with that observed with ttc staining. among the four reconstruction methods, osem3d provided the best assessment of infarct size (r2 = 0.994, p...

myocardial free wall rupture is a catastrophic complication of acute myocardial infarction, and prognosis will depend on the prompt diagnosis by echocardiography, extension of infarct size, and prompt surgical treatment. free wall rupture concomitant with ventricular septal defect (vsd) may be more complicated for management. a case of a 69-year-old man with myocardial free wall rupture and vsd...

detected in any patient by this method. Fourteen patients had raised serum creatine kinase activity (up to 5000 IU/1, normal range < 170 lU/i) and raised serum aspartate transaminase activity (up to 150 IU/1, normal < 35 IU/1). In all cases enzyme activity fell after admission to hospital. Peak serum creatine kinase activity was not significantly related to weight, sex, level of consciousness, ...

OBJECTIVE Familiarize clinicians with recent information regarding the diagnosis and treatment of ST-segment elevation myocardial infarction. DATA SOURCES PubMed search and review of relevant medical literature. SUMMARY Definition, pathophysiology, clinical presentation, diagnosis, and treatment of ST-segment elevation myocardial infarction are reviewed. CONCLUSIONS Patients with ST-segme...

t one time, patients with acute myocardial infarction (AMI) would have has as poor a prognosis as fatal arrhythmia, cardiac rupture or left ventricular dysfunction. In modern countries, mortality after AMI has been greatly decreased by developments in coronary revascularization, antiarrhythmic agents and the treatment of hypertension and congestive heart failure using angiotensin-converting enz...
