2024年10月8日 · Inferior myocardial infarction (MI) accounts for 40-50% of all MIs. It generally has a more favourable prognosis than anterior myocardial infarction (in-hospital mortality only 2-9%), however certain associated features indicate a worse outcome. ECG diagnostic criteria

2017年4月2日 · LCX occlusions are an underdiagnosed clinical entity in ACS management. Despite non-diagnostic ECG findings, total LCX occlusion should be considered in clinical presentations consistent with ACS. If the patient appears clinically worse than the ECG findings would suggest, consider discussing with interventional cardiology about pursuing PCI ...

Occlusion in the left circumflex coronary artery (LCx) Areas supplied by the left circumflex coronary artery. In 90% of individuals, the coronary circulation is right-dominant, meaning that the PDA is given off by the RCA. In these individuals, the LCx only supplies the basal and mid parts of the posterolateral wall.

An acute myocardial infarction (MI) caused by occlusion of the left circumflex coronary artery (LCX) might, due to the limitations of standard 12-lead ECG, be classified more often as non-ST-elevation acute coronary syndrome (NSTEACS) than occlusions of the right coronary artery (RCA) or left anterior descending (LAD) artery.

2011年10月1日 · Compared to occlusions of other major coronary arteries, patients presenting with acute left circumflex (LCx) occlusion usually have ST-segment elevation on the electrocardiogram <50% of the time, potentially delaying treatment and …

Acute coronary syndrome (ACS) with occlusion of the left circumflex coronary artery (LCX) poses diagnostic problems that may lead to a delay in reperfusion. From a group of 1,269 consecutive patients with ACS, 138 patients with ACS due to LCX ...

2024年3月1日 · Acute occlusion of the left circumflex artery often times does not result in classic ST-elevation on ECG. Presence of ST-elevation from a LCx occlusion is likely determined by its location and coronary artery dominance. Acute proximal LCx occlusion in left and co-dominant systems is associated with lack of classic ST-elevation.

2001年7月24日 · At least five different ST-segment criteria help to identify the RCA or the LCX as the culprit artery in patients with acute inferior MI. One of these, the amount of ST-segment depression in lead aVR, has not been reported previously and needs validation in a larger study.

To investigate the diagnostic value of electrocardiographic (ECG) ST-segment in acute inferior myocardial infarction (AIMI) caused by the left circumflex branch (LCX). A total of 240 clinical cases with AIMI in our hospital were retrospectively ...

NSTEMI patients (pts) with occlusions have worse outcomes than those without occlusions, but no studies specifically examine outcomes in acute myocardial infarction (AMI) pts with LCx/OM occlusion. This study aims to define the incidence of NSTEMI in pts presenting with LCx/OM occlusion and analyzes clinical characteristics and outcomes in ...
