Background: Consciousness disturbance is one of the major clinical signs associated with shock state, but its prognostic value has not been previously evaluated in cardiovascular shock patients. We ...aimed to evaluate the prognostic value of neurological status for 30-day mortality in cardiovascular shock patients without out-of-hospital cardiac arrest (OHCA). Methods and Results: Patients with out-of-hospital onset cardiovascular shock were recruited from the Japanese Circulation Society Shock Registry. Neurological status upon hospital arrival was evaluated using the Japan Coma Scale (JCS). Patients were divided into 4 groups according to the JCS: alert, JCS 0; awake, JCS 1–3 (not fully alert but awake without any stimuli); arousable, JCS 10–30 (arousable with stimulation); and coma JCS 100–300 (unarousable). The primary endpoint was 30-day all-cause death. In total, 700 cardiovascular shock patients without OHCA were assessed. The coma group was associated with a higher incidence of 30-day all-cause death compared with other groups (alert, 15.3%; awake, 24.4%; arousable, 36.8%; coma, 48.5%, P<0.001). Similar trends were observed in etiologically divergent subgroups (acute coronary syndrome, non-ischemic arrhythmia, and aortic disease). On multivariate Cox regression analysis, arousable (hazard ratio HR, 1.82; 95% CI: 1.16–2.85, P=0.009) and coma (HR, 2.72; 95% CI: 1.76–4.22, P<0.001) (reference: alert) independently predicted 30-day mortality. Conclusions: Neurological status upon hospital arrival was useful to predict 30-day mortality in cardiovascular shock patients without OHCA.
Polypharmacy was reported to be associated with increased mortality in various populations. However, there is a scarcity of data on status of polypharmacy and association with long-term mortality in ...patients who underwent percutaneous coronary intervention (PCI). Among 12,291 patients who underwent first PCI in the CREDO-Kyoto PCI/CABG registry Cohort-3, we evaluated the number of medications at discharge from index PCI hospitalization, and compared long-term mortality across the 3 groups divided by the tertiles of the number of medications. The median number of medications was 6 (interquartile range: 5 to 8), and 88.0% of the patients were on >=5 medications. Most of medications were those related to cardiovascular disease. Patients taking more medications were older and more often had co-morbidities and guideline-indicated medications. The cumulative 5-year incidence of all-cause death increased incrementally with increasing number of medications (Tertile 1 <=5: 13.1%, Tertile 2 6 to 7: 13.9%, and Tertile 3 >=8: 18.0%, log-rank p <0.001). After adjusting confounders, the mortality risks of Tertile 2 and Tertile 3 relative to Tertile 1 were no longer significant (Tertile 2: hazard ratio 0.93; 95% confidence interval 0.84 to 1.04; p = 0.23, and Tertile 3: hazard ratio 0.91; 95% confidence interval 0.81 to 1.03; p = 0.14, respectively). In conclusion, in a real-world population of patients who underwent PCI, approximately 90% of patients were on >=5 medications. Increasing medications was associated with higher crude incidence of all-cause death, whereas adjusted mortality risks were similar regardless of the number of medications. These data might suggest that achievement of optimal medical therapy would be preferred, even if it might increase the number of medications used.
Previous studies have demonstrated that use of intravascular ultrasound (IVUS) during percutaneous coronary intervention (PCI) was associated with lower incidence of death, myocardial infarction, and ...target vessel revascularization. Recently, optical coherence tomography (OCT) has emerged as an alternative intravascular imaging device with better resolution. The aim of this study was to investigate frequency and prognostic impact of IVUS or OCT-guided PCI during urgent revascularization for acute myocardial infarction diagnosed by the universal definition. A total of 2788 patients who underwent urgent PCI were selected from a multicenter, Japanese registry of acute myocardial infarction diagnosed by universal definition (J-MINUET). Frequency, clinical characteristics and prognostic impact of the IVUS-, or OCT- guided PCI were investigated. Clinical endpoint was in-hospital death. Angiography-, IVUS-, and OCT-guided urgent PCI were performed in 689 (24.7%), 1947 (69.8%), and 152 (5.5%) patients. In-hospital death in each group was 10.4%, 5.1%, and 3.3%, respectively (
P
< 0.01). By univariate and multivariate logistic regression analysis, IVUS-guided PCI (vs. angiography-guided PCI, OR 0.49, 95% CI 0.30–0.81,
P
= 0.006) was a significant independent predictor of in-hospital death. Intravascular imaging guided-PCI was frequently adopted during urgent PCI for acute myocardial infarction diagnosed by universal definition and was associated with better in-hospital survival.
•Periprocedural myocardial infarction (PMI) remains a common complication of percutaneous coronary intervention.•Statin reduces PMI by preventing coronary microvascular dysfunction.•We investigate ...the effect of evolocumab on PMI in stable coronary artery disease patients.
Percutaneous coronary intervention (PCI) is a standard treatment in patients with stable coronary artery disease (CAD); however, periprocedural myocardial infarction (PMI) remains a common complication of PCI. Aggressive lipid-lowering therapy with statin has shown to reduce the incidence of PMI by preventing coronary microvascular dysfunction. It is unclear whether evolocumab, a potent lipid-lowering agent, could diminish microvascular damage after PCI. The EVOCATION trial (jRCTs051180022) is a multicenter, randomized, open-label, active-controlled, parallel-group, exploratory, investigator-initiated clinical study to evaluate whether pretreatment with evolocumab could decrease the index of microvascular resistance (IMR) after PCI in patients with stable CAD. This study population consists of 100 patients with stable CAD who will undergo PCI and have high low-density lipoprotein cholesterol levels despite administration of maximum tolerated dose of statins for at least 2 weeks. Eligible patients are randomized in a 1:1 ratio to receive either evolocumab 140 mg every 2 weeks in addition to standard of care treatment or standard of care treatment only for 2–6 weeks before PCI. The primary endpoint is IMR after PCI. The EVOCATION trial will evaluate whether pretreatment with evolocumab reduces periprocedural microvascular damage in patients with stable CAD undergoing PCI.

Cardiovascular disease is a major cause of death among travelers, but the clinical characteristics and clinical outcomes of patients who develop acute coronary syndrome (ACS) while traveling have not ...been assessed. We evaluated 2548 patients with ACS who underwent primary percutaneous coronary intervention (PCI) between 1999 and 2015 and compared the incidences of all-cause and cardiac death during follow-up between travelers and locals. We assessed 192 (7.5%) patients who developed ACS while traveling. These patients were younger and had a higher prevalence of ST-elevation myocardial infarction than local patients. During a median follow-up period of 5.3 years, 632 (24.8%) all-cause deaths were identified, including 310 cardiac deaths (12.2%). Kaplan-Meier analysis revealed that the cumulative incidence of all-cause death was significantly lower among the travelers than locals (P = 0.001, log-rank test). Multivariate Cox hazard analysis revealed that travel was significantly associated with a lower rate of all cause death (hazard ratio, 0.53; 95% confidence interval, 0.33-0.80; P = 0.002). Cardiac mortality did not significantly differ between travelers and locals (P = 0.29). Patients with ACS treated with primary PCI while traveling had more favorable long-term clinical outcomes than local patients. Appropriate initial treatments and secondary preventions might improve the prognosis of travelers.
Thrombolysis in Myocardial Infarction Risk Score for Secondary Prevention (TRS2°P) is a contemporary risk scoring system for secondary prevention based on nine clinical factors. However, this scoring ...system has not been validated in other populations. The aim of this study was to validate the TRS2°P in patients with acute myocardial infarction (AMI) treated with primary percutaneous coronary intervention (PCI) in a nationwide registry cohort. Among 3283 consecutive patients with AMI enrolled in the Japanese registry of acute Myocardial INfarction diagnosed by Universal dEfiniTion (J-MINUET), a total of 2611 patients who underwent primary PCI were included in this study. The performance of the TRS2°P to predict major adverse cardiovascular events (MACE) composed of all-cause death, non-fatal MI, and non-fatal stroke up to 3 years in the present cohort was evaluated. The TRS2°P had modest discriminative performance in this J-MINUET cohort with a c-statistic of 0.63, similar to that in the derived cohort (TRA2°P-TIMI50, c-statistic 0.67). A strong graded relationship between the TRS2°P and 3-year cardiovascular event rates was also observed in the J-MINUET cohort. Age ≥ 75 years, Killip ≥ 2, prior stroke, peripheral artery disease, anemia, and non-ST-elevation myocardial infarction were identified as independent factors for the incidence of MACE. The TRS2°P modestly predicted secondary cardiovascular events among patients with AMI treated by primary PCI in a nationwide cohort of Japan. Further studies are needed to develop a novel risk score better predicting secondary cardiovascular events.
Background:The comparative efficacy of second-generation (G2) vs. first-generation (G1) drug-eluting stents (DES) for calcified coronary lesions is unknown.Methods and Results:We compared the 3-year ...clinical outcomes of patients with G1- or G2-DES according to the presence or absence of calcified coronary lesions as assessed in an angiographic core laboratory using data from 2 large-scale prospective multicenter randomized trials, RESET and NEXT. G1-DES and G2-DES were implanted in 299 and 1,033 patients, respectively, in the Calc stratum (≥1 lesion with moderate/severe calcification), and 1,208 and 3,550 patients, respectively, in the Non-calc stratum (no/mild calcification). The patients in the Calc stratum had a significantly higher adjusted risk for the primary outcome measure (any target-lesion revascularization (TLR)) than those in the Non-calc stratum (HR: 1.38, 95% CI: 1.11–1.71, P=0.004). The cumulative 3-year incidence of any TLR was not significantly different between the G1-DES and G2-DES groups in both the Calc and Non-calc strata (12.1% vs. 9.7%, P=0.22, and 6.8% vs. 6.1%, P=0.44, respectively). After adjusting for confounders, the effect of G2DES relative to G1-DES for any TLR remained insignificant in both the Calc and Non-calc strata (HR: 0.78, 95% CI: 0.48–1.25, P=0.3, and HR: 0.84, 95% CI: 0.61–1.17, P=0.31, respectively, P interaction=0.55).Conclusions:The effect of G2-DES relative to G1-DES for TLR was not significantly different regardless of the presence or absence of lesion calcification.
The European Society of Cardiology (ESC) recommends a 0-h/1-h (0/1-h) algorithm to classify patients with suspected non-ST-segment elevation myocardial infarction (NSTEMI). However, reliable evidence ...about patients who present early after the onset of symptoms is limited, likely because high-sensitivity cardiac troponin (hs-cTn) values cannot increase sufficiently within that time. This study aimed to evaluate the outcomes in real-world situations that utilized the 0/1-h algorithm.
In a prospective, international, multicenter cohort study that enrolled 1638 patients presenting with acute chest pain to the emergency department, we assessed the performance of the 0/1-h algorithm using hs-cTnT and the associated 30-day rates of major adverse cardiac events: death and acute myocardial infarction (AMI).
Among 1074 patients, the prevalence of AMI was 16.0%. An approximately 60.1% (n = 645) of patients visited the hospital within 3 h after onset of chest pain (less than 1 h; 18.2% n = 196, less than 2 h; 27.5% n = 295, and less than 3 h; 14.3% n = 154). Moreover, the prevalence rates of AMI were similar at all times (1 h, 16.8%; 1–2 h, 20.7%; 2–3 h, 18.2%; p = .5). According to the ESC 0/1-h algorithm, the distribution patterns of rule-out, observe, and rule-in groups were similar; however, none of the patients was diagnosed with AMI or cardiac death in the rule-out group.
This study revealed the applicability of the 0/1-h algorithm for the management of early presenters.
•None of the 30-day major advanced cardiac events was associated with the 0/1-h algorithm for the management of very early presenters.•A distribution patterns of rule-out, observe, and rule-in groups were similar at 1 h, 1–2 h, and 2–3 h after chest pain onset.•Strategies that incorporate a HEART score with the algorithm can be used for clinical implementation.
The management of non-valvular atrial fibrillation (AF) has evolved with the development of direct oral anticoagulants (DOACs). However, data regarding the effectiveness and safety of DOACs outside ...clinical trial settings are limited, and off-label dosing of DOACs has not been thoroughly investigated.
We examined the clinical outcomes of patients with non-valvular AF in the RAFFINE registry, a prospective registry of Japanese patients with AF who were followed-up for more than 3 years.
Among 3706 patients with non-valvular AF, 42.5% received warfarin and 44.7% received DOACs at baseline. The administration of DOACs increased annually. The mean CHADS2 and HAS-BLED scores were significantly higher in the warfarin group. The unadjusted all-cause mortality, cardiovascular mortality, and incidence of major bleeding events were higher in the warfarin group. The incidence of ischemic stroke/systemic embolism was not different between groups. After adjustment for baseline characteristics, the incidence of these events was not different between groups. Off-label dosing was performed for 32% of patients in the DOAC group, but this did not affect clinical outcomes.
The all-cause mortality, cardiovascular mortality, and incidence of major bleeding events were higher in the warfarin group than in the DOAC group. After adjustment, warfarin use was not associated with an increase in these events. Off-label dosing of DOACs is not rare and is not associated with reduced effectiveness. The impact of off-label dosing of each DOAC on clinical events should be assessed using a larger population.

Background: There is a scarcity of studies comparing the clinical outcomes after percutaneous coronary intervention (PCI) for women and men stratified by the presentation of acute coronary syndromes ...(ACS) or stable coronary artery disease (CAD).Methods and Results: The study population included 26,316 patients who underwent PCI (ACS: n=11,119, stable CAD: n=15,197) from the CREDO-Kyoto PCI/CABG registry Cohort-2 and Cohort-3. The primary outcome was all-cause death. Among patients with ACS, women as compared with men were much older. Among patients with stable CAD, women were also older than men, but with smaller difference. The cumulative 5-year incidence of all-cause death was significantly higher in women than in men in the ACS group (26.2% and 17.9%, log rank P<0.001). In contrast, it was significantly lower in women than in men in the stable CAD group (14.2% and 15.8%, log rank P=0.005). After adjusting confounders, women as compared with men were associated with significantly lower long-term mortality risk with stable CAD but not with ACS (hazard ratio HR: 0.75, 95% confidence interval CI: 0.69–0.82, P<0.001, and HR: 0.92, 95% CI: 0.84–1.01, P=0.07, respectively). There was a significant interaction between the clinical presentation and the mortality risk of women relative to men (interaction P=0.002).Conclusions: Compared with men, women had significantly lower adjusted mortality risk after PCI among patients with stable CAD, but not among those with ACS.
