Introduction: We have recently reported the cause of microcirculatory damage after percutaneous coronary intervention (PCI) in ST-segment elevation myocardial infarction (STEMI) patients can be evaluated by analyzing the thermodilution-derived coronary blood flow pattern (CBFP), and only the capillary destruction pattern was associated with poor mid-term clinical outcomes. In this study, we extend our research on the contribution of acute hyperglycemia on microcirculatory damage and long-term clinical outcomes in STEMI patient. Methods: Ninety-seven consecutive STEMI patients undergoing primary PCI were prospectively enrolled. Using a pressure sensor/thermistor-tipped guidewire, CBFP was assessed from the thermodilution-curves immediately after successful PCI. All patients were classified into 3 groups according to the shape of thermodilution curve: no microvascular damaged group (n=47), arteriole microemboli group (n=33), or capillary destruction group (n=17). Blood glucose levels were measured on admission. Major adverse cardiac events (MACE) were defined as a composite of cardiac death, myocardial infarction, and heart failure rehospitalization within 3 years. Results: Mean admission glucose level was significantly higher in the capillary destruction group than in the microemboli and no microvascular damaged groups (259±134, 162±66, and 153±60 mg/dL, respectively, p<0.0001). These findings were similar when the analysis was limited to non-diabetic patients. The incidence of MACE was also higher in the capillary destruction group compared with the microemboli and no microvascular damaged groups (71, 19, and 16%, respectively, p<0.0001). On multivariate Cox regression analysis, the capillary destruction pattern was the independent predictor of MACE (hazard ratio, 9.41; 95%CI 2.28-38.8; p=0.001). In the multivariate logistic regression analysis, higher glucose level on admission remained as an independent risk factor of the capillary destruction pattern (per 10mg/dL increase, odds ratio, 1.10; 95%CI 1.10-1.22; p=0.002). Conclusions: Hyperglycemia on admission increases the risk of microvascular damage secondary to the capillary destruction and subsequent poor long-term clinical outcomes in STEMI patients.

Abstract Background Inflammation is an indicator of worse clinical outcomes following acute myocardial infarction. Eosinopenia was identified as a surrogate of inflammation in sepsis and obstructive airway disease. Whether this readily-available marker has any impact on long term outcomes following ST-segment elevation myocardial infarction (STEMI) is yet to be determined. Purpose We sought to study the incidence and relationship between eosinopenia and infarct severity and whether low eosinophil had impact on clinical outcomes following STEMI. Methods 606 consecutive STEMI patients undergoing primary PCI from a large volume single centre were enrolled. Low eosinophil count was defined as <40 cells/ml from samples within 2 -hours post reperfusion. Primary endpoint was defined as composite of death, MI, stroke, unplanned revascularisation, re-admission for heart failure over 3.5 years follow up. Results 65% of patients had eosinopenia. Patients in the low eosinophil group had larger infarct size as measured by troponin value [2934 vs. 1177ng/L, P<0.001] and left ventricle (LV) systolic function on echocardiography [48% vs. 50%, P=0.029]. Thehre was a modest correlation between eosinophil count and both troponin (r=−0.25, P<0.001) and ejection fraction (r=0.10, P=0.017). The primary endpoint was higher in eosinopenic patients (28.8% vs. 20.4%, HR 1.49, 95% CI 1.05 to 2.13, P=0.023) (Figure). The difference was mainly driven from higher percentage of unplanned revascularisations (8.2% versus 2.9%, P=0.012) (Table). Low eosinophil count was an independent predictor of adverse cardiovascular events, beyond infarct severity, in elderly, non-diabetic patients (HR 2.04, 95% CI 1.04 to 4.01, P=0.038). Incidence rate of major clinical Clinical characteristics Low eosinophil Normal eosinophil P value Long term clinical events 28.8% (112) 20.4% (42) 0.026 Long term mortality 14.1% (55) 11.1% (23) 0.31 Long term MI 6.9% (27) 4.9% (10) 0.32 Long term unplanned revascularisation 8.2% (32) 2.9% (6) 0.012 Long term re-admission CCF 6.7% (26) 4.9% (10) 0.37 Long term stroke 2.6% (10) 1% (2) 0.19 Conclusions Eosinopenia is a readily-available marker which was associated with a larger infarcts and worse clinical outcomes over long term follow up.

Abstract Background Whether very elderly women with acute coronary syndromes (ACS) should receive aggressive percutaneous coronary intervention (PCI) is still controversial. We assessed the effectiveness and long-term clinical outcomes of successful PCI in this population and identified prognostic factors which might contribute to the incidence of major adverse cardiovascular and cerebrovascular events (MACCE) in the very elderly female PCI cohort. Methods Female ACS patients aged ≥ 80 years were consecutively enrolled (n = 729) into the study. All the patients were divided into female PCI group (n = 232) and medical group (n = 497). MACCE was followed up, including non-fatal myocardial infarction (MI), stroke, heart failure requiring hospitalization (HFRH), cardiovascular (CV) death, and the composite of them. After propensity score matching (1:1), the incidences of MACCE were compared between the two groups. Clinical and coronary artery lesion characteristics were compared between the female PCI patients with (n = 56) and without MACCE (n = 176). Multivariate Cox regression analysis was performed to identify risk factors which independently associated with MACCE in the female PCI patients. MACCE of male PCI patients, who aged ≥ 80 years and hospitalized in the same period (n = 264), was also compared with that of the female PCI patients. Results A total of 32% very elderly female ACS patients received PCI in the present study. (1) Compared to female medical group, PCI procedure significantly alleviated the risks of MACCE: non-fatal MI (6.2% vs. 20.2%, P < 0.001), HFRH (10.9% vs. 22.5%, P = 0.012), CV death (12.4% vs. 28.7%, P < 0.001) and the composite MACCE (24.0% vs. 44.2%, P < 0.001) during the median follow-up period of 36 months. (2) Between very elderly female and male PCI patients, there were no significant differences in occurrence of MACCE (P = 0.232) and CV death (P = 0.951). (3) Multivariate Cox analysis revealed that ST-segment elevation myocardial infarction (STEMI) (HR 1.944, 95% CI 1.11–3.403, P = 0.02) and elevated log- N-Terminal pro-brain natriuretic peptide (NT-proBNP) (HR 1.689, 95% CI 1.029–2.773, P = 0.038) were independently associated with the incidence of MACCE in the female PCI patients. Conclusions PCI procedure significantly attenuated the risk of MACCE and improved the long-term clinical outcomes in very elderly female ACS patients. Aggressive PCI strategy may be reasonable in this population.

Background Contemporary real‐world data on stroke in patients presenting with ST‐segment–elevation myocardial infarction (STEMI) are scarce. Methods and Results We evaluated the incidence, trends, cause, and predictors of stroke from 2003 to 2019 in 4 large regional STEMI programs in the upper Midwest that use similar transfer and treatment protocols. We also evaluated the long‐term impact of stroke on 5‐year mortality. Multivariate logistic and Cox regression analysis was used to identify variables independently associated with stroke in patients presenting with STEMI and identify variables associated with 5‐year mortality. A total of 12 868 patients presented with STEMI during the study period. Stroke occurred in 98 patients (0.76%). The incidence of stroke remained stable over time (0.5% in 2003, 1.2% in 2019; P ‐trend=0.22). Most (75%) of strokes were ischemic, with a median time to stroke symptoms of 14 hours after primary percutaneous coronary intervention (interquartile range, 4–72 hours), which led to a small minority (3%) receiving endovascular treatment and high in‐hospital mortality (18%). On multivariate regression analysis, age (increment of 10 years) (odds ratio [OR], 1.32; 95% CI, 1.10–1.58; P ‐value=0.003) and preintervention cardiogenic shock (OR, 2.03; (95% CI, 1.03–3.78; P =0.032)) were associated with a higher risk of in‐hospital stroke. In‐hospital stroke was independently associated with increased risk of 5‐year mortality (hazard ratio, 2.01; 95% CI, 1.13–3.57; P =0.02). Conclusions In patients presenting with STEMI, the risk of stroke is low (0.76%). A stroke in patients presenting with STEMI is associated with significantly higher in‐hospital (18%) and long‐term mortality (35% at 5 years). Stroke was associated with double the risk of 5‐year death.

Introduction: PCI has evolved with technological advance, improvement of operators’ techniques and medical therapy for secondary prevention. Despite these improvements, diabetes remains a negative predictor. To date, little is known regarding improvement of clinical outcomes in diabetic patients with PCI. We examined a temporal trend of long-term clinical outcomes in diabetic cohort across the different generations. Hypothesis: We hypothesized that clinical outcomes would improve with advances of PCI. Methods: We analyzed data of diabetic patients with PCI in Juntendo University from 1984 to 2010. The patients were divided into three groups according to the procedure data (POBA-era; January 1984 - December 1997, BMS-era; January 1998 - July 2004 and DES-era; August 2004 - February 2010). Primary endpoint was a composite of major adverse cardiovascular events including all-cause mortality, non-fatal myocardial infarction, non-fatal stroke and revascularization. Results: A total of 1544 patients were examined (POBA-era; 374, BMS-era; 494 and DES-era; 676). The mean age was higher in DES-era. A higher prevalence of hypertension and dyslipidemia was observed in DES-era. The success rate of PCI was lower among the patients in POBA-era. Kaplan-Meier estimation for 3-year MACE was significantly different among the eras (Figure 1). Multivariable Cox regression analysis showed that DES-era was a predictor for long-term MACE (DES- vs BMS era; HR 0.50, 95%, CI 0.38 - 0.66, P < 0.001, DES- vs POBA-era; HR 1.60, 95% CI 0.34-27.9, P = 0.6). Conclusions: Long-term clinical outcomes in diabetic patients who underwent PCI were more favorable in DES-era, despite the higher risk profiles.

Myocardial infarction with non-obstructive coronary arteries (MINOCA) is a heterogeneous entity with an inflammatory etiopathogenesis. This study investigated the prognostic value of the neutrophil-to-lymphocyte ratio (NLR) in patients with MINOCA. Coronary angiographies performed between June 2015 and August 2018 were analyzed retrospectively and included 72 patients with MINOCA and 248 controls with normal coronary angiograms. The predictors of mortality were determined by univariate Cox regression analysis. The mean age of the subjects was 46 ± 9 years, and 176 (55%) were female. Median follow-up was 21 (max: 42) months. Neutrophil-to-lymphocyte ratio was significantly higher in the MINOCA group than in the controls ( P < .01). During long-term follow-up, the number of deaths was 6 in the MINOCA group and none in the control patients ( P < .01). Univariate Cox regression analysis revealed that the NLR (hazard ratio: 1.24, 95% confidence interval: 1.09-1.41, P = .001) was a predictor of mortality in patients with MINOCA. Kaplan–Meier analysis also showed that patients with MINOCA had relatively higher mortality rate (long-rank test; P < .01). In conclusion, the NLR is significantly higher in patients with MINOCA compared with controls, and it is a predictor of long-term mortality.

Time To Diagnosis

BACKGROUND: There has been a rapid increase in screening for colorectal cancer (CRC) over the past several years in North America. This could paradoxically lead to worsening outcomes if the system is not adapted to deal with the increased demand. For example, this could create increased wait times for endoscopy and delayed time to CRC diagnosis, which could worsen clinical outcomes such as stage at diagnosis and/or survival. No previous Canadian study has evaluated the association between time to CRC diagnosis and clinical outcomes.METHODS: The present historical cohort study used Manitoba’s population-based cancer registry and Manitoba Health administrative databases. The effect of time to diagnosis on patient survival was evaluated using Cox regression analysis with adjustment for stage at diagnosis, grade of CRC, age, sex, socioeconomic status, comorbidity index score and year of CRC diagnosis. The association between time to diagnosis and CRC stage at diagnosis was evaluated using multivariate logistic regression analysis.RESULTS: The median time to CRC diagnosis increased significantly from 72 days (95% CI 61 days to 83 days) in 2004 to 105 days (95% CI 64 days to 129 days) in the first three months of 2009 (P=0.04). There was no significant association between time to diagnosis and survival. Individuals with the longest time to diagnosis were less likely to have stage III/IV CRC at diagnosis (quartile 4 versus quartile 1: OR 0.50 [95% CI 0.33 to 0.75).CONCLUSION: Time to CRC diagnosis is continuing to increase in Manitoba. Although the present study did not detect a significant negative clinical effect of increasing time to diagnosis, additional studies are required.

Clinical Variables

The use of hydraulic silicate cements (HSCs) for vital pulp therapy has been found to release calcium and hydroxyl ions promoting pulp tissue healing and mineralized tissue formation. The present study investigated whether HSCs such as mineral trioxide aggregate (MTA) affect their biological and antimicrobial properties when used as long-term pulp protection materials. The effect of variables on treatment outcomes of three HSCs (ProRoot MTA, OrthoMTA, and RetroMTA) was evaluated clinically and radiographically over a 48–78 month follow-up period. Survival analysis was performed using Kaplan–Meier survival curves. Fisher’s exact test and Cox regression analysis were used to determine hazard ratios of clinical variables. The overall success rate of MTA partial pulpotomy was 89.3%; Cumulative success rates of the three HSCs were not statistically different when analyzed by Cox proportional hazard regression analysis. None of the investigated clinical variables affected success rates significantly. These HSCs showed favorable biocompatibility and antimicrobial properties in partial pulpotomy of permanent teeth in long-term follow-up, with no statistical differences between clinical factors.

Purpose: Evaluate the impact of hybrid operating room (HOR) guidance on the long-term clinical outcomes following fenestrated and branched endovascular repair (F-BEVAR) for complex aortic aneurysms. Materials and Methods: Prospectively collected registry data were retrospectively analyzed to compare the procedural, short- and long-term outcomes of consecutive F-BEVAR performed from January 2010 to December 2014 under standard mobile C-arm versus hybrid room guidance in a high-volume aortic center. Results: A total of 262 consecutive patients, including 133 patients treated with a mobile C-arm equipped operating room and 129 with a HOR guidance, were enrolled in this study. Patient radiation exposure and contrast media volume were significantly reduced in the HOR group. Short-term clinical outcomes were improved despite higher case complexity in the HOR group, with no statistical significance. At a median follow-up of 63.3 months (Q1 33.4, Q3 75.9) in the C-arm group, and 44.9 months (Q1 25.1, Q3 53.5, p=0.53) in the HOR group, there was no statistically significant difference in terms of target vessel occlusion and limb occlusion. When the endograft involved 3 or more fenestrations and/or branches (complex F-BEVAR), graft instability (36% vs 25%, p=0.035), reintervention on target vessels (20% vs 11%, p=0.019) and total reintervention rates (24% vs 15%, p=0.032) were significantly reduced in the HOR group. The multivariable Cox regression analysis did not show statistically significant differences for long-term death and aortic-related death between the 2 groups. Conclusion: Our study suggests that better long-term clinical outcomes could be observed when performing complex F-BEVAR in the latest generation HOR.
