A 77-year-old female presented with loss of consciousness, blood pressure of 90/60 mmHg, and heart rate of 47 bpm. At admission, highly sensitive Trop-T and lactate were elevated, and an electrocardiogram revealed an infero-posterior ST elevation myocardial infarction. Echocardiography revealed a depressed left ventricular ejection fraction with abnormal wall motion in the infero-posterior region and hyperkinetic apical movement along with severe mitral regurgitation (MR). Coronary angiography showed a hypoplastic right coronary artery, 100% thrombotic occlusion of the dominant left circumflex (LCx) artery, and 75% stenosis in the left anterior descending (LAD) artery. Substantial hemodynamic improvement with the reduction of acute ischemic MR was achieved by the initiation of an Impella 2.5, which is a transvalvular axial flow pump, and successful percutaneous coronary intervention (PCI) was conducted with stents to the LCx. The patient was weaned off the Impella 2.5 in 5 days, received staged PCI to LAD, and was later discharged after completion of the staged PCI to LAD.

Patients with acute myocardial infarction (AMI) triaged as life-threatening are transferred to our emergency medical care center (EMCC). However, data on these patients remain limited. We aimed to compare the characteristics and AMI prognosis of patients transferred to our EMCC with those transferred to our cardiovascular intensive care unit (CICU) using whole and propensity-matched cohorts.We analyzed the data of 256 consecutive AMI patients transferred from the scene to our hospital by ambulance between 2014 and 2017. The EMCC and CICU groups comprised 77 and 179 patients, respectively. There were no significant between-group age or sex differences. Patients in the EMCC group had more disease severity score and had the left main trunk identified as the culprit more frequently (12% versus 0.6%, P < 0.001) than those in the CICU group; however, the number of patients with multiple culprit vessels did not differ. The EMCC group had a longer door-to-reperfusion time (75 [60, 109] minutes versus 60 [40, 86] minutes, P< 0.001) and a higher in-hospital mortality (19% versus 4.5%, P < 0.001), especially from non-cardiac causes (10% versus 0.6%, P < 0.001), than the CICU group. However, peak myocardial creatine phosphokinase did not significantly differ between the groups. The EMCC group had a significantly higher 1-year post-discharge mortality than the CICU group (log-rank, P = 0.032); this trend was maintained after propensity score matching, although the difference was not statistically significant (log-rank, P = 0.094).AMI patients transferred to the EMCC exhibited more severe disease and worse overall in-hospital and non-cardiac mortality than those transferred to the CICU.

BACKGROUND: Because development of acute coronary syndrome (ACS) worsens the prognosis of patients with coronary artery disease, preventing recurrent ACS is crucial. However, the degree to which secondary prevention treatment goals are achieved in patients with recurrent ACS is unknown. METHODS: 214 consecutive ACS patients were classified as having First ACS (n=182) or Recurrent ACS (n=32), and the clinical characteristics of these groups were compared. Fifteen patients died or developed cardiovascular (CV) events during hospitalization, and the remaining 199 patients were followed from the date of hospital discharge to evaluate subsequent CV events. RESULTS: Patients in the Recurrent ACS group were older than those in the First ACS group (76.8±10.8 years vs 68.8±13.4 years, p=0.002) and had a higher rate of diabetes mellitus (DM) (65.6% vs 36.8%, p=0.003). The rate of achieving a low-density lipoprotein cholesterol (LDL-C) level of <70 mg/dL in the Recurrent ACS group was only 28.1%, even though 68.8% of these patients were taking statins. An HbA1c level of <7.0% was achieved in 66.7% of patients with recurrent ACS who had been diagnosed with DM. Overall, 12.5% of patients with recurrent ACS had received optimal treatment for secondary prevention. CV events after hospital discharge were noted in 37.9% of the Recurrent ACS group and 21.2% of the First ACS group (log-rank test: p=0.004). However, recurrent ACS was not an independent risk factor for CV events (adjusted hazard ratio: 2.09, 95% confidence interval: 0.95 to 4.63, p=0.068). CONCLUSION: Optimal treatment for secondary prevention was not achieved in some patients with recurrent ACS, and achievement of the guideline-recommended LDL-C goal for secondary prevention was especially low in this population.

Gastrointestinal (GI) bleeding worsens the outcomes of critically ill patients in the intensive care unit (ICU). Owing to a lack of corresponding data, we aimed to investigate whether GI bleeding during cardiovascular-ICU (C-ICU) admission in acute cardiovascular (CV) disease patients is a risk factor for subsequent CV events. Totally, 492 consecutive C-ICU patients (40.9% acute coronary syndrome, 22.8% heart failure) were grouped into GI bleeding (n = 27; 12 upper GI and 15 lower GI) and non-GI bleeding (n = 465) groups. Thirty-nine patients died or developed CV events during hospitalization, and 453 were followed up from the date of C-ICU discharge to evaluate subsequent major adverse CV events. The GI bleeding group had a higher Acute Physiology and Chronic Health Evaluation II score (20.2 ± 8.2 vs. 15.1 ± 6.8, p < 0.001), higher frequency of mechanical ventilator use (29.6% vs. 13.1%, p = 0.039), and longer C-ICU admission duration (8 [5-16] days vs. 5 [3-8] days, p < 0.001) than the non-GI bleeding group. The in-hospital mortality rate did not differ between the groups. Of those who were followed-up, CV events after C-ICU discharge were identified in 34.6% and 14.3% of patients in the GI and non-GI bleeding groups, respectively, during a median follow-up period of 228 days (log rank, p < 0.001). GI bleeding was an independent risk factor for subsequent CV events (adjusted hazard ratio: 2.23, 95% confidence interval: 1.06-4.71; p = 0.035). GI bleeding during C-ICU admission was independently associated with subsequent CV events in such settings.

BACKGROUND: In the modern US cardiovascular intensive care unit (CICU), the incidence of non-cardiovascular disorders has increased and non-cardiovascular disorders are associated with an increase in morbidity and mortality. In Japan, however, data regarding the association between non-cardiovascular disorders and outcomes in the CICU are limited. METHODS: This study examined 490 consecutive admissions to a closed CICU at the Nippon Medical School Hospital from January to December 2017. Characteristics, diagnoses, treatments, and outcomes of admitted patients were identified. RESULTS: The most common primary diagnosis was acute coronary syndrome (50.4%), followed by acute heart failure (20.0%), arrhythmia (6.7%), and non-cardiovascular diseases (3.7%). The mortality rate and median length of stay (LOS) in the CICU were 4.7% and 4 (interquartile range, 2-8) days, respectively. Of all patients, 42.2% (n = 207) developed non-cardiovascular complications such as acute respiratory failure, acute kidney injury, or sepsis during CICU stay. Multivariate logistic regression analysis revealed that acute respiratory failure and sepsis were significantly associated with mortality in the CICU (odds ratio, 11.014 and 25.678, respectively; both p<0.05). The multiple linear regression analysis showed that acute kidney injury was significantly associated with LOS in the CICU (β=0.144, p = 0.002). CONCLUSIONS: Approximately half of patients admitted to the CICU had non-cardiovascular disorders including non-cardiovascular disease and non-cardiovascular complications, which were significantly associated with mortality and LOS in the CICU.
