Effect of statin therapy before Q-wave myocardial infarction on myocardial perfusion.

Recent studies emphasized the non-lipid-lowering effects of hydroxymethylglutaryl coenzyme A reductase inhibitors on endothelial function, inflammation, and platelet activation in patients with stable atherosclerosis. This study sought to evaluate the impact of statin pretreatment in patients with acute myocardial infarction (AMI) on level of systemic inflammation and myocardial perfusion. A total of 253 consecutive patients undergoing primary angioplasty on a native vessel within 12 hours of AMI were divided into a group with statin pretreatment (n = 86) and control patients (n = 167).

Association of C-reactive protein and myocardial perfusion in patients with ST-elevation acute myocardial infarction.

This study sought to evaluate the relation between C-reactive protein (CRP) on admission of patients with acute myocardial infarction (AMI) and myocardial perfusion as defined by postintervention angiographic myocardial blush grade (MBG) and their impact on subsequent mortality. The patient population comprised 191 consecutive patients with AMI undergoing PTCA within 12h of symptom onset on a native vessel. Patients were divided based on the CRP level on admission (Rolf Greiner BioChemica, Germany, cutpoint for the assay CRP: 5mg/l) into a group with elevated CRP (>or=5mg/l) and a group with normal CRP.

Usefulness of myocardial blush grade early and late after primary coronary angioplasty for acute myocardial infarction in predicting left ventricular function.

This study sought to analyze the evolution of myocardial perfusion during follow-up after primary angioplasty for acute myocardial infarction (AMI) and relate it to final left ventricular (LV) function. In 101 patients with a first AMI, angiographic myocardial blush grade (MBG) was analyzed immediately after intervention and at follow-up 7.5 +/- 5.

Prediction of clinical outcome after mechanical revascularization in acute myocardial infarction by markers of myocardial reperfusion.

Objectives: We sought to evaluate and compare recently suggested parameters of reperfusion after angioplasty in acute myocardial infarction (AMI) for risk stratification during long-term follow-up.

Background: Abnormal myocardial perfusion has a detrimental impact on survival. Several parameters of reperfusion have been evaluated in controlled study populations for risk stratification.
