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.

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

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.

2024年10月29日 · Lateral wall myocardial infarction (MI) is an uncommon acute myocardial infarction resulting from atherosclerotic plaque rupture and thrombus formation in the left circumflex coronary artery or one of its branches.

In 90% of individuals, the right coronary artery gives off the posterior descending artery (PDA) which supplies the inferior wall of the left ventricle. When the RCA gives off PDA, the anatomy is referred to as right-dominant system (if the Lcx gives off …

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.

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 …

2024年10月8日 · Three broad categories of lateral infarction: Anterolateral STEMI due to LAD occlusion. Inferior-posterior-lateral STEMI due to LCx occlusion. Isolated lateral infarction due to occlusion of smaller branch arteries such as the D1, OM or ramus intermedius. High Lateral STEMI. ST elevation is present in the high lateral leads (I and aVL).
