Troponin T measurement after myocardial infarction can identify left ventricular ejection of less than 40%.
AIM To determine whether measurement of serum troponin T concentration after first acute myocardial infarction can be used to identify patients with a left ventricular ejection fraction of < 40%, who have an adverse prognosis. METHODS Troponin T concentration was measured, and coronary and left ventriculography performed in 50 consecutive patients with acute myocardial infarction. Angiographi...
متن کاملProspective evaluation of the role of routine cardiac troponin T measurement to identify left ventricular ejection fraction < 40% after first myocardial infarction.
Serial measurements of creatine kinase (CK) and its MB isoenzyme (CK-MB) and calculation of area under the curve (AUC) or peak value can be used to estimate infarct size. Peak values usually occur 20–24 hours postinfarction but release kinetics are affected by reperfusion (spontaneous or therapeutic). Regular, frequent samples must be obtained following admission, not a convenient approach for ...
متن کاملMeasurement of left ventricular ejection fraction after acute myocardial infarction. A serial cross sectional echocardiographic study.
Left ventricular ejection fraction was assessed by biplane cross sectional echocardiography in 65 patients with a first acute myocardial infarction on the first day. In 30 patients (group 1) measurements were repeated on the third day and in another 35 patients (group 2) at three months. Changes in ejection fraction of 0.05 or less were arbitrarily called insignificant. In group 1 only two pati...
متن کاملDecreased serine207 phosphorylation of troponin T as a biomarker for left ventricular remodelling after myocardial infarction.
AIMS Chronic heart failure following myocardial infarction (MI) is characterized by progressive left ventricular remodelling (LVR). Despite significant improvements in MI management, LVR remains a frequent complication. Although several risk factors have been identified, such as infarct size, LVR is difficult to predict in clinical practice. METHODS AND RESULTS Using a rat model of MI and pho...
متن کاملThe effect of eight weeks of moderate-intensity endurance training on myocardial capillary density, ejection fraction and left ventricular shortening fraction in male rats with myocardial infarction
Background and objective: Vascular obstruction and impaired blood flow and oxygen delivery cause a myocardial infarction and limit a personchr('39')s function. Therefore, finding a way to create new arteries and replace blocked arteries has always been of interest to researchers, including exercise physiologists. Therefore, this study was conducted to evaluate the effect of eight weeks of moder...
