Despite advancements in pharmacological therapy and refinement of the tools and technique of primary percutaneous coronary intervention (PCI) and coronary artery bypass surgery, patients with acute myocardial infarction (AMI) complicated by profound cardiogenic shock (CS) still have unacceptably high in-hospital mortality and unfavorable long-term outcome. Thus, there is an imminent need of a new and safe treatment modality in the management of AMI complicated by profound CS. Growing evidence suggests that extracorporeal membrane oxygenator (ECMO)-supported primary PCI is an effective therapeutic option for saving lives under such conditions. In this review, we describe and interpret the potential role of circulatory mechanical support by ECMO in the setting of AMI complicated by profound CS for improving clinical outcomes.

Background Cytotoxic T lymphocyte antigen 4 (CTLA-4) is a particularly important molecule in down-regulating T-cell expansion and cytokine production. The purpose of the present study was to determine the frequency distribution of an A/G single nucleotide polymorphism at position 49 in exon 1 of the CTLA-4 gene, which may be a functional related-genetic risk marker for the development of ST-segment elevation (ST-se) acute myocardial infarction (AMI). Methods and Results A total of 503 consecutive patients, consisting of 250 ST-se AMI patients undergoing primary coronary angioplasty (group 1), 203 angina pectoris patients undergoing elective coronary angioplasty (group 2) and 50 patients with chest pain and normal coronary angiographic findings (group 3), were enrolled in the present study. The frequency of the G/G genotype was significantly higher in group 1 (53.2%) than in groups 2 (33.0%) and 3 (36.0%) (p=0.0005). In group 1, patients with a G/G genotype had significantly higher levels of high-sensitivity C-reactive protein and white blood cell counts, and much higher incidences of multi-vessel disease, greater lesion lengths, advanced congestive heart failure (≥ class 3) and 30-day mortality, than patients with G/A or A/A genotypes (p values<0.05 in all cases). Multivariate analysis of the enrolled baseline variables (age, gender, diabetes mellitus, smoking, hypertension and hypercholesterolemia) and the genotypes (G/G, A/G and A/A) demonstrated that G/G genotype is the only independent predictor of development of AMI (p<0.0001). Conclusion The G/G genotype polymorphism of the CTLA-4 gene is associated with increased risk of AMI. (Circ J 2007; 71: 1213 - 1218)

We investigated the accuracy of various bleeding risk scores to estimate the bleeding risk in patients with acute myocardial infarction (AMI) managed with percutaneous coronary intervention (PCI) access via the radial artery.We retrospectively enrolled 1,651 patients who were definitively diagnosed with ST-elevation myocardial infarction (STEMI) or non-STEMI (NSTEMI). We assessed the predictive validities of 30-day bleeding events in various scoring systems using receiver operating characteristic curves.Overall, ACUITY-HORIZONS exhibited the highest area under the curve to predict 30-day bleeding, followed by ACTION and CRUSADE; HAS-BLED displayed the lowest score. With a cut-off of 17, ACUITY-HORIZONS demonstrated the best discrimination for the Thrombolysis in Myocardial Infarction (TIMI) 30-day serious bleeding rate. We observed significant differences among all-cause death, cardiovascular death, and major adverse cardiac events between the ACUITY-HORIZONS groups with a score of ≤ 17 and > 17. ACUITY-HORIZONS score > 17, initial systolic blood pressure (SBP) < 90 mmHg, and Killip III and IV upon admission positively predicted the 30-day bleeding risk, whereas myocardial infarction (MI) and TIMI major bleeding within 30 days, heart failure at admission, and initial SBP < 90 mmHg positively predicted the 30-day mortality.Comparatively, ACUITY-HORIZON is the most reliable system in predicting 30-day bleeding for patients with AMI via transradial PCI. In the transradial scenario, bleeding and MI within 30 days are substantially related to 30-day mortality.

To investigate the postprocedural cardiovascular events and vascular outcomes, including hand ischemia and neurological compromise, after transulnar (TU) catheterization in ipsilateral radial artery occlusion.Previous randomized trials have shown that the transulnar (TU) approach for coronary angiogram and intervention has safety and outcomes similar to those of the transradial (TR) approach. However, the safety of the TU procedure when ipsilateral radial artery occlusion occurs is unknown.We retrospectively reviewed 87 TU cases with ipsilateral radial artery occlusion confirmed by a forearm angiogram. Eighty percent of these patients had a history of ipsilateral radial artery cannulation or surgery. We avoided the use of over-sized sheaths or applied a sheathless approach during surgery.No ulnar artery occlusion was observed by subsequent Doppler ultrasound or pulse oximetry. No patient developed hand ischemia or serious complications requiring surgery or blood transfusion during the follow-up period of 32.2 ± 24.0 months. Review of the preprocedural forearm angiograms showed that 95.7% of the patients possessed significant collaterals supplying flow from the interosseous artery to the occluded radial artery remnant. Thus, the blood circulation to the palmar arch and digital vessels was maintained even when the ulnar artery was temporarily occluded by an in-dwelling ulnar arterial sheath.TU catheterization was safe in patients with coexisting ipsilateral radial artery occlusions and feasible for use in complex intervention procedures. Cautious manipulation of ulnar artery cannulation and hemostasis helped decrease the risk of hand ischemia.
