A case report: unmasking a singular culprit for cardiogenic shock: looking beyond the coronary tree.

ABSTRACT: Cardiogenic shock remains challenging in its therapy and aetiology. A 74-year-old woman admitted for cardiogenic shock requiring mechanical ventilation and high-dose inotropics and vasopressors with an electrocardiogram showing left ventricular (LV) lateral wall ischaemia had diffuse coronary artery disease but TIMI III flow in the coronary tree. An echocardiogram showed a suspicious mass invading the left ventricle and computed tomography scan revealed an advanced lung cancer with LV wall and pulmonary artery invasion as the cardiogenic shock cause. When managing cardiogenic shock, it is important to consider different and not obvious diagnosis. A high level of clinical suspicion and multimodality imaging assessment was very important in the present case to attain the diagnosis.

Project description:ImportanceMyocardial infarction with a culprit lesion located in the left main or proximal left anterior descending artery compared with other coronary segments is associated with more myocardium at risk and worse clinical outcomes.ObjectiveTo evaluate the association of culprit lesion location with outcomes of culprit-lesion-only percutaneous coronary intervention with optional staged revascularization vs immediate multivessel percutaneous coronary intervention in patients with multivessel disease, myocardial infarction, and cardiogenic shock.Design, setting, and participantsPost hoc analysis of the Culprit Lesion Only Coronary Intervention vs Multivessel Coronary Intervention in Cardiogenic Shock (CULPRIT-SHOCK), an investigator-initiated randomized, open-label clinical trial. Patients with multivessel disease, acute myocardial infarction, and cardiogenic shock were enrolled at 83 European centers from April 2013 through April 2017.InterventionsPatients were randomized to culprit-lesion-only percutaneous coronary intervention with optional staged revascularization or immediate multivessel percutaneous coronary intervention (1:1). For this analysis, patients were stratified by culprit lesion location in the left main or proximal left anterior descending artery group and other-culprit-lesion location group.Main outcomes and measuresEnd points included a composite of death or kidney replacement therapy at 30 days and death at 1 year.ResultsThe median age of the study population was 70 (interquartile range, 60-78 years) and 524 of the study participants were men (76.4%). Of the 685 patients, 33.4% constituted the left main or proximal left anterior descending artery group and 66.6% the other-culprit-lesion location group. The left main or proximal left anterior descending artery group had worse outcomes compared with the other-culprit-lesion location group (56.8% vs 47.5%; P = .02 for the composite end point at 30 days and 59.8% vs 50.1%; P = .02 for death at 1 year). In both groups, culprit-lesion-only vs immediate multivessel percutaneous coronary intervention was associated with a reduced risk of the composite end point at 30 days (49.1% vs 64.3% and 44.1% vs 50.9%; P for interaction = .27). At 1 year, culprit-lesion-only vs immediate multivessel percutaneous coronary intervention was associated with a significantly reduced risk of death in the left main or proximal left anterior descending artery but not the other-culprit-lesion location group (50.0% vs 69.6%; P = .003 and 49.8% vs 50.4%; P = .89; P for interaction = 0.02).Conclusions and relevanceIn patients with multivessel disease with myocardial infarction and cardiogenic shock, a culprit lesion located in the left main or proximal left anterior descending artery vs other coronary segments was associated with worse outcomes. These patients may especially benefit from culprit-lesion-only percutaneous coronary intervention with optional staged revascularization, although further investigation is needed to confirm this finding.Trial registrationClinicalTrials.gov Identifier: NCT01927549.
