BACKGROUND: Circulating progenitor cells (PC) can positively influence the healing of ischaemic myocardium. Cardiovascular risk factors including diabetes mellitus (DM) may have a negative influence on both number and recruitment of PC. Recent evidence suggests that less differentiated CD133(+)PC contribute to myocardial healing and are promising candidates for therapy. Therefore, ...

Presence of severe left ventricular (LV) diastolic function has been shown to independently predict risk of heart failure or death after acute myocardial infarction (AMI). We aimed to determine whether common echocardiographic parameters and (LV) diastolic function evaluated during AMI hospitalization can predict the risk of rehospitalization, up to 1 ...

OBJECTIVES: All patients should undergo formal assessment of ventricular function following acute myocardial infarction (AMI). Cardiac magnetic resonance (CMR) is not widely used as a test before discharge in AMI patients. This study sought to determine the impact of contrast-enhanced CMR (ceCMR) scanning before discharge in addition to standard transthoracic ...

Acute myocardial infarction complicated by cardiogenic shock (AMI-CS) is the leading cause of in-hospital death for patients admitted with acute coronary syndromes. Expert guidelines for the care of AMI-CS patients recommend early revascularization with intra-aortic balloon pump support. Ventricular assist devices (VADs) offer the advantages of providing greater and longer-term ...

AIM: Predictions of the onset of acute myocardial infarction (AMI) in high risk individuals are of great clinical importance. Among various risk factors, elevated levels of oxidized low density lipoprotein (ox-LDL) in plasma have been shown to reflect unstable coronary plaques. Coronary calcification is a common finding in the elderly, ...
Nijmeijer R - - 2008
BACKGROUND: Secretory type-II phospholipase A(2) (sPLA(2)-II) is a cardiovascular risk marker since higher levels of this acute phase protein imply an increased risk for coronary artery disease. Moreover, it is hypothesized that local activity of sPLA(2)-II in the atherosclerotic plaque facilitates an inflammatory response to induce plaque instability or rupture. ...
