Severe Stenosis

Acute myocardial infarction (AMI) caused by severe stenosis of left main coronary artery (LMCA) presenting with cardiogenic shock and pulmonary edema during noncardiac surgery is uncommon, but a catastrophic event. A 77-year-old male with cholangiocarcinoma underwent hepatectomy. During the surgery, he presented with cardiogenic shock, which did not respond to infusion administration or vasopressor. A transesophageal echocardiogram revealed anterior, septal, and lateral severe hypokinesia and impaired left ventricular function. Emergent coronary angiogram showed severe stenosis of LMCA. The patient underwent primary percutaneous coronary intervention (PCI) under the support of intra-aortic balloon pump, followed by extracorporeal membrane oxygenation. The chest roentgenogram showed pulmonary edema. Two days after PCI, he successfully underwent hepatectomy and bile duct resection. Early identification of the cause of hemodynamic instability during noncardiac surgery and invasive strategy are important for minimizing the myocardial injury and improving clinical outcomes in AMI of LMCA.

The Mean

We aim to describe the in-hospital outcomes of the first reported Canadian cohort of patients with cardiogenic shock and acute myocardial infarction (MI) due to acute and total occlusion of the left main coronary artery, treated with initial percutaneous coronary intervention (PCI). Acute left main thromboses with cardiogenic shock were identified (N = 8) from a retrospective consecutive cohort of high risk left main PCI (N = 56) performed at our institution from 2004–2009. The mean age was 62.3 ± 13.2 years, with 6 (75%) male patients. Successful PCI was performed in all patients, with thrombectomy utilized in 4 patients (50%), stenting in 7 patients (88%), and intra-aortic balloon pump augmentation in 7 patients (88%). Two patients (25%) required extracorporeal membrane oxygenation (ECMO) and 2 other patients required ventricular assist devices. Post-PCI coronary artery bypass grafting (CABG) was performed for 2 patients (25%). The mean SYNTAX score was 26.6 ± 10.5. The mean logistic EuroSCORE was 30.4 ± 12.6%. In-hospital mortality occurred in 3 patients (38%). Acute left main occlusion is a rare but devastating presentation of myocardial infarction, invariably with cardiogenic shock. Emergent PCI may be an effective method to acutely revascularize this subset of patients; however, aggressive post-PCI care including ECMO, CABG, and ventricular support may be required to improve patient survival.

Abstract Background and purpose Acute myocardial infarction (AMI) due to left main coronary artery (LMCA) occlusion is a rare event, often catastrophic. Limited data are available about management and outcomes of patients with acute LMCA occlusion, including those presenting with cardiogenic shock (CS) at hospital admission. This study sought to describe patients with AMI due unprotected LMCA occlusion presenting with CS and to evaluate their in-hospital outcomes and 1-year mortality. Methods In this retrospective 2-center study, we identified 7630 patients with ST-segment elevation myocardial infarction (STEMI) or hight risk non-ST segment elevation myocardial infarction who underwent to emergent coronary angiography between January 2008 and December 2020. Among this cohort, we analysed 94 patients who presented with unprotected LMCA occlusion (Thrombolysis In Myocardial Infarction – TIMI ≤2) and divided them in 2 groups according to presence of signs of cardiogenic shock at admission: CS and no-CS. Results Of 94 patients with AMI due LMCA occlusion, 52 patients presented with CS (53.3%). Mean age was 62.8±11.5 years in CS and 62.0±15.9 years in no-CS patients, p=0.766. In both groups, most patients were male. STEMI presentation was more frequent in CS group (80.4% vs. 52.4%, p=0.004). Severe systolic dysfunction of left ventricle was more frequent in CS patients (81.1% vs. 33.3%, p<0.001). Compared to no-CS patients, CS group shown more often TIMI=0 (67.3% vs. 26.2%, p<0.001), collateral coronary circulation Rentrop 0–1 (95.3% vs. 75.0%, p=0.008), and slow-reflow/no-reflow phenomena (30.6% vs 3.8%, p=0.019) in emergent coronary angiography. The need of invasive mechanical ventilation (68.9% vs. 21.4%, p<0.001), and haemodialysis (20.5% vs. 2.4%, p=0.010) were more prevalent in CS patients. Likewise, mechanical circulatory support (MCS) was more frequently used in patients presented with CS (52.9% vs. 26.2%, p=0.009). In subgroup analysis, MCS implantation was not a survival predictor in CS patients (Odds ratio: 3.9 [95% confidence interval: 0.4 to 36.3], p=0.229). Ultimately, in-hospital mortality (78.8% vs. 16.7%, p<0.001) was higher in CS patients. On the other hand, in hospital survivors, there was no significant differences in 1-year mortality (11.1% vs. 23.5%, p=0.42) between both groups. Conclusions Nearly half of patients with AMI due LMCA occlusion presented with CS signs at first medical evaluation. This subgroup of patients had higher in-hospital mortality compared to those without CS, despite MCS implantation. Whether the use of a specific MCS device or whether early use of MCS can change the outcome remains to be elucidated. CS patients who survive to index-hospitalization, had similar long-term outcomes compared to no-CS patients. Further studies are imperative in this population to refine initial medical treatment in order to improve their prognosis. FUNDunding Acknowledgement Type of funding sources: None.
