STUDY OBJECTIVES Prior studies have proposed several ECG criteria for identifying the culprit artery in patients with acute inferior myocardial infarction (MI). We applied each criterion to our patients to assess its utility. In doing so, we discovered a previously unreported, but highly useful, criterion utilizing lead aVR. STUDY DESIGN Retrospective review. PATIENTS Thirty consecutive pat...

BACKGROUND In-stent restenosis is considered to be a gradual and progressive condition and there is scant data on myocardial infarction (MI) as a clinical presentation. METHODS AND RESULTS Of 2,462 consecutive patients who underwent percutaneous coronary intervention between June 2001 and December 2002, clinical in-stent restenosis occurred in 212 (8.6%), who were classified into 3 groups: ST...

It is rare to observe ST-segment elevation in only the anterior leads and not the inferior leads during right coronary artery occlusion. We describe a case with acute myocardial infarction (MI) by right coronary artery occlusion who developed ST-segment elevation only in the precordial leads V1 to V3.

OBJECTIVES Several publications have demonstrated increased 30-day mortality in patients admitted on Saturdays or Sundays compared with weekdays. We sought to determine whether this was true for two different cohorts of patients admitted with acute myocardial infarction (MI). METHODS AND RESULTS Thirty-day mortality data were obtained for 3757 patients who had been admitted to the Belfast Hea...

Acute posterior wall myocardial infarction (PMI) occurs in up to 20% of cases of acute myocardial infarction (MI), with the vast majority occurring along with inferior or lateral acute MI.1 A true PMI is considered more rare, with an incidence of approximately 3.3%.2 The term PMI is used for necrosis of the part of the left ventricle located beneath the atrioventricular sulcus.3 The majority of...

UNLABELLED AIM OF FAST-MI 2010: To gather data on characteristics, management and outcomes of patients hospitalised for acute myocardial infarction (AMI) at the end of 2010 in France. INTERVENTIONS To provide cardiologists and health authorities national and regional data on AMI management every 5 years. SETTING Metropolitan France. 213 academic (n=38), community (n=110), army hospitals (n...

The aim of this study was to describe differences in the characteristics and short- and long-term prognoses of patients with first acute myocardial infarction (MI) according to the presence of ST-segment elevation or non-ST-segment elevation. From 2001 and 2003, 2,048 patients with first MI were consecutively admitted to 6 participating Spanish hospitals and categorized as having ST-segment ele...

OBJECTIVES The purpose of this study was to assess the association of myocardial salvage by cardiac magnetic resonance (CMR) with left ventricular (LV) remodeling and early ST-segment resolution in patients with acute myocardial infarction (MI). BACKGROUND Experimental studies revealed that MI size is strongly influenced by the extent of the area at risk (AAR), limiting its accuracy as a mark...
