Long-term prognostic value of CK-MB and the troponins after angioplasty in patients with stable angina.

Objectives: The long-term prognostic value (> 5 years) of elevated cardiac biomarkers after elective coronary angioplasty is yet not clear. Most previous studies have included high risk, unstable patients and with conflicting results. The aim of this study was to determine the prognostic value of CK-MB mass vs.

Long-term prognostic value of cardiac troponin I and T versus creatine kinase-MB mass after cardiac surgery in low-risk patients with stable symptoms.

The long-term prognostic value of elevated cardiac biomarkers after elective cardiac surgery is not clear. The recent guidelines for diagnosing perioperative infarcts have advocated the use of similar thresholds for creatine kinase-MB (CK-MB) mass and the cardiac troponins. However, few previous data are available comparing these biomarkers after cardiac surgery, and it is not clear whether postoperative elevations of the troponins can be treated the same as elevations of CK-MB.

Elevated CK-MB values after routine angioplasty predicts worse long-term prognosis in low-risk patients.

Objectives: The long-term prognostic value (>5 years) of elevated cardiac biomarkers after elective coronary angioplasty is yet not clear. Most previous studies have included high risk, unstable patients. The aim of this study was to determine the prognostic value of CK-MB mass > or = three times the reference after elective angioplasty in low-risk patients with stable angina.

Long-term prognostic value of creatine kinase-myocardial band mass after cardiac surgery in low-risk patients with stable angina.

Objectives: The long-term prognostic value (>5 years) of elevated cardiac biomarkers after elective cardiac surgery is not clear. Most previous studies have included high-risk, unstable patients. The aim of this study was to determine the prognostic value of creatine kinase-myocardial band (CK-MB) mass after elective cardiac surgery in low-risk patients with stable angina.

Temporal pattern of cardiac troponin I after thoracotomy and lung surgery.

Background: Several studies have shown that patients with perioperative myocardial infarction (MI) are at higher risk for subsequent cardiac events and the identification of these patients is important. However, the diagnosis of perioperative MI can be difficult in many cases. The cardiac troponins are biomarkers with high cardiospecificity, and the aim of this study was to assess cTnI and cTnT among other cardiac biomarkers after thoracotomy and lung surgery.

Release of cardiac troponin I after temporally graded acute coronary ischaemia with electrocardiographic ST depression.

Background: Elevation of cardiac biochemical markers and ST segment depression in the electrocardiogram have important roles in the risk stratification of unstable coronary syndromes. We assessed graded duration of acute coronary ischaemia with ST depression versus release of cardiac troponin I (cTnI) and conventional cardiac markers in 15 ischaemic pigs and 11 controls.

Methods: Coronary ischaemia was induced via percutaneous technique by semiinflating an angioplasty balloon in the left circumflex artery.

Percutaneous assessment of coronary blood flow and cardiac biomarkers.

The aim of this study was to compare blood flow determined by coloured microspheres vs. Doppler intravascular ultrasound (US) combined with angiography. A second endpoint was to assess cardiac troponin I (cTnI) as a marker of myocardial injury.
