RESUMEN

BACKGROUND: In an aging society, percutaneous coronary intervention (PCI) for super-elderly patients is commonly performed in clinical practice. However, data are scarce regarding the clinical features and outcomes of this population. METHODS: This multicenter observational study enrolled patients aged over 90 years who underwent PCI across 10 hospitals between 2011 and 2020. The study included patients presenting with acute coronary syndrome (ACS) and chronic coronary syndrome (CCS). The occurrence of all-cause and cardiac deaths during hospitalization and after discharge was investigated. RESULTS: In total, 402 patients (91.9 ±â€¯2.0 years, 48.3 % male) participated in the study, of whom 77.9 % presented with ACS. The rate of in-hospital death was significantly higher in patients with ACS compared to patients with CCS (15.3 % vs. 2.2 %, p < 0.001). The estimated cumulative incidence rates of all-cause death were 24.3 %, 39.5 %, and 60.4 % at 1, 3, and 5 years, respectively. No significant difference was observed in the occurrence of all-cause death between patients with ACS and CCS. Regarding causes of death after discharge, non-cardiac deaths accounted for just over half of the cases. CONCLUSION: This study highlights the clinical features and long-term clinical course of patients aged over 90 years who underwent PCI in a real-world setting. Patients presenting with ACS exhibited a higher rate of in-hospital mortality compared to those with CCS. Following discharge, both ACS and CCS patients experienced comparable and substantial increases in the incidence rates of both cardiac and non-cardiac mortality over time, and a more holistic management approach is warranted.

RESUMEN

BACKGROUND: The proportion of young females among the patients who undergo percutaneous coronary intervention (PCI) is relatively small, and information on their clinical characteristics is limited. This study investigated the clinical characteristics and prognostic factors for future cardiac events in young females who underwent PCI. METHODS: This multicenter observational study included 187 consecutive female patients aged < 60 years who underwent PCI in seven hospitals. The primary composite endpoint was the incidence of cardiac death, nonfatal myocardial infarction, and target vessel revascularization. RESULTS: The mean patient age was 52.1 ± 6.1 years and 89 (47.6%) had diabetes, and renal dysfunction (an estimated glomerular filtration rate < 60 mL/min/1.73 m2) was observed in 38 (20.3%). During a median follow-up of 3.3 years, the primary endpoint occurred in 28 patients. The Cox proportional hazards models showed that renal dysfunction was an independent predictor for the primary endpoint (hazard ratio 3.04, 95% confidence interval 1.25-7.40, p = 0.01), as well as multivessel disease (hazard ratio 2.79, 95% confidence interval 1.12-6.93, p = 0.03). Patients with renal dysfunction had a significantly higher risk for the primary endpoint than those without renal dysfunction. CONCLUSIONS: Renal dysfunction was strongly associated with future cardiac events in young females who underwent PCI.

RESUMEN

BACKGROUND: Patients with a right dominant coronary artery anatomy account for a significant proportion of acute myocardial infarction cases, and this condition is associated with a better prognosis. However, there are limited data on the impact of coronary dominance on patients with acute total/subtotal occlusion of unprotected left main coronary artery (ULMCA). METHODS: This study aimed to assess the impact of right coronary artery (RCA) dominance on long-term mortality in patients with acute total/subtotal occlusion of the ULMCA. From a multicenter registry, 132 cases of consecutive patients who had undergone emergent percutaneous coronary intervention (PCI) due to acute total/subtotal occlusion of the ULMCA were reviewed. RESULTS: Patients were classified into two groups according to the size of their RCA (dominant RCA group, n = 29; non-dominant RCA group, n = 103). Long-term outcomes were examined according to the presence of dominant RCA. Cardiopulmonary arrest (CPA) occurred in 52.3 % of patients before revascularization. All-cause death was significantly lower in the dominant RCA group than in the non-dominant RCA group. In the Cox regression model, dominant RCA was an independent predictor of all-cause death, as well as total occlusion of ULMCA, collateral from RCA, chronic kidney disease, and CPA. Patients were further analyzed according to the degree of stenosis of the ULMCA; patients with non-dominant RCA and total occlusive ULMCA had the worst outcome compared with the other groups. CONCLUSIONS: A dominant RCA might improve long-term mortality in patients with acute total/subtotal occlusion of the ULMCA who were treated with PCI.

RESUMEN

BACKGROUND: Frailty is one of the most serious health problems in older individuals with cardiovascular disease. Moreover, frailty progression is associated with subsequent adverse outcomes; therefore, the prevention of frailty progression is an important clinical issue. However, the incidence and predictors of frailty progression following acute myocardial infarction have not yet been fully elucidated. METHODS: The present study is a sub-analysis of an observational multicenter registry retrospectively evaluating clinical outcomes of 288 octogenarians who underwent primary percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction (STEMI) between January 2014 and December 2016 at five hospitals. We identified 244 patients who survived until discharge and evaluated frailty at baseline and discharge using the Clinical Frailty Scale (CFS). We defined frailty progression as an increase of at least one level in the CFS score at discharge from baseline and assessed the predictors of frailty progression. RESULTS: Frailty progression was observed in 29.5% of patients. Patients with frailty progression were older, had more severe conditions with a higher prevalence of Killip 4 status and mechanical circulatory support use, more frequently experienced in-hospital events such as stroke (4/72, 6% vs. 0/172, 0%, p = 0.007), and had longer hospital stays than those without frailty progression [19 (11-35) vs. 13 (9-19) days, p<0.01]. Multivariate analysis showed that age (odds ratio 1.08, 95% confidence interval 1.00-1.17, p = 0.046) and Killip 4 status at baseline (odds ratio 3.34, 95% confidence interval 1.26-8.85, p = 0.01) were significant predictors of frailty progression. CONCLUSIONS: In-hospital frailty progression was commonly observed in octogenarians with STEMI who underwent primary PCI and survived until discharge, and was associated with more severe clinical conditions.

RESUMEN

The outbreak of coronavirus disease 19 (COVID-19) has had a great impact on medical care. During the COVID-19 pandemic, the rate of hospital admissions has been lower and the rate of in-hospital mortality has been higher in patients with acute coronary syndrome (ACS) in Western countries. However, in Japan, it is unknown whether the COVID-19 pandemic has affected the incidence of ACS. In the study, eleven hospitals in the Tokai region participated. Among enrolled hospital, we compared the incidence of ACS during the COVID-19 pandemic (April and May, 2020) with that in equivalent months in the preceding year as the control. During the study period; April and May 2020, 248 patients with ACS were admitted. Compared to April and May 2019, a decline of 8.1% [95% confidence interval (CI) 5.2-12.1; P = 0.33] in admissions for ACS was observed between April and May 2020. There was no significant difference in the strategy for revascularization and in-hospital deaths between 2019 and 2020. In conclusion, the rate of admission for ACS slightly decreased during the COVID-19 pandemic, compared to the same months in the preceding year. Moreover, degeneration of therapeutic procedures for ACS did not occur.

RESUMEN

BACKGROUND: Data regarding the clinical features, outcomes and prognostic factors in patients presenting with acute total/subtotal occlusion of the unprotected left main coronary artery (LMCA) remain limited.Methods and Results:From a multi-center registry, 134 patients due to acute total/subtotal occlusion of the unprotected LMCA were reviewed. Emergency room (ER) status classification was defined according to the presence of cardiogenic shock and cardiopulmonary arrest (CPA) in the ER (class 1=no cardiogenic shock; class 2= cardiogenic shock but not CPA; and class 3=CPA). In-hospital mortality and cerebral performance category (CPC) as the endpoints were evaluated. One-half (67/134) of the enrolled patients presented with total occlusion of the unprotected LMCA. Regarding ER status classification, class 1, 2, and 3 were observed in 30.6%, 45.5%, and 23.9% of the patients, respectively. In-hospital mortality occurred in 73 (54.5%) patients; of the remaining patients, 52 (85.3%) could be discharged with a CPC 1 or 2. ER status classification (odds ratio 4.4 [95% confidence interval: 2.33-10.67]; P<0.001) and total occlusion of the unprotected LMCA (odds ratio 8.29 [95% confidence interval 2.93-23.46]; P<0.001) were strong predictors of in-hospital mortality. CONCLUSIONS: Acute total/subtotal occlusion involving the unprotected LMCA appeared to be associated with high in-hospital mortality. ER status classification and initial flow in the unprotected LMCA were significant predictive factors of in-hospital mortality.

RESUMEN

BACKGROUND: The deterioration of renal function is a strong prognostic predictor in patients with coronary artery disease. Although percutaneous coronary intervention (PCI) has sometimes resulted in improved renal function (IRF) in acute coronary syndrome (ACS) patients, its clinical implications have not been fully elucidated. This study aimed to investigate the prevalence and predictors of IRF after PCI and its relationship with long-term renal outcomes. METHODS: In this retrospective observational cohort study, we examined data from 177 ACS patients with non-dialysis advanced renal dysfunction (estimated glomerular filtration rate [eGFR] < 30 mL/min/1.73 m2) who underwent PCI. Patients with and without IRF were compared in terms of baseline demographic, clinical, and procedural characteristics and renal outcomes. IRF was defined as a 20% increase in eGFR from baseline at 7 or 30 days after the index PCI. RESULTS: IRF was observed in 66 (37.3%) patients. ST-elevation myocardial infarction and shock during PCI were independent predictors of IRF. Patients were followed up for a median of 695 days. Kaplan-Meier analyses demonstrated that patients with IRF had the lower incidence of initiation of permanent dialysis than those without IRF (Log-rank P = 0.015). CONCLUSIONS: IRF was relatively common in non-dialysis patients with ACS and advanced renal dysfunction who underwent PCI. ST-elevation myocardial infarction and shock, which may be indicative of hemodynamic instability during PCI, were independent predictors of IRF. Further, IRF was associated with favorable renal outcomes. Hemodynamic stabilization may be important for improving the short-term and long-term renal outcomes of high-risk patients.

RESUMEN

BACKGROUND: Epicardial adipose tissue (EAT) is considered to play a critical role in vascular endothelial function. Coronary artery spasm has been postulated to be a causal factor in vascular endothelial abnormalities and atherosclerosis. This study aimed to investigate the relationship between coronary artery spasm and EAT volume, total abdominal adipose tissue (AAT) area, and abdominal visceral adipose tissue (AVAT) area. METHOD: Among patients undergoing coronary computed tomography (CT) to evaluate coronary artery disease, we identified 110 patients who did not have significant coronary artery stenosis and underwent a coronary spasm provocation test with cardiac catheterization. They were divided into two groups according to the results of the spasm provocation test: spasm-positive and spasm-negative. EAT volume, total AAT area, and AVAT area were evaluated using CT images. RESULTS: Seventy-seven patients were included in the spasm-positive group and 33 patients in the spasm-negative group. There were no significant differences in baseline clinical characteristics between the two groups, except for the prevalence of current smoking (48% vs. 27%, p = 0.04). EAT volume was significantly higher in the spasm-positive group (108 ±â€¯38 mL vs. 87 ±â€¯34 mL, p = 0.007), while no significant difference was seen in total AAT area (280 ±â€¯113 cm2 vs. 254 ±â€¯128 cm2, p = 0.32) or AVAT area (112 ±â€¯54 cm2 vs. 98 ±â€¯55 cm2, p = 0.27). Multivariate logistic analysis indicated that EAT volume (per 10 cm3) (odds ratio, 1.198; 95% confidence interval, 1.035-1.388; p = 0.016) was a significant predictor of coronary artery spasm. CONCLUSION: Our results suggest that EAT has a strong association with coronary artery spasm, while AAT may not.

RESUMEN

BACKGROUND: Spontaneous coronary artery dissection (SCAD) has recently been recognized as a cause of acute coronary syndrome (ACS), especially in young women. However, the characteristics, optimal treatment, and prognosis of patients who experience SCAD have not been fully described. METHODS: Data were retrospectively collected from a multicenter registry. Among 187 young women less than 60 years of age who underwent percutaneous coronary intervention, 19 (10.2%) with SCAD were identified through coronary angiography. Clinical characteristics and outcomes were investigated. RESULTS: Those with SCAD less frequently exhibited coronary risk factors, such as diabetes, dyslipidemia, and smoking, than those without SCAD. Intense emotional and/or physical stress was more frequently observed as a prominent precipitating factor in cases of SCAD. All 19 SCAD patients presented with ACS, 7 of whom were treated using stents, and the other 12 treated without stents. During a median follow-up of 960 days (interquartile range, 686-1504 days), two recurrent coronary artery dissections occurred within 7 days, both of which occurred in a vessel other than that in which primary dissection occurred. There were no deaths or recurrent dissection after 1 week. CONCLUSION: SCAD was not uncommon among young Japanese women requiring percutaneous coronary intervention. Patients with SCAD exhibited fewer coronary risk factors and more precipitating factors than those without SCAD, and long-term clinical outcomes after an early period appeared to be favorable.

RESUMEN

The aim of the present study was to evaluate the renal outcomes, including the time course of renal function, after elective PCI in patients with advanced renal dysfunction and to assess the predictors of renal dysfunction progression. This is a subanalysis of a previous observational multicenter study that investigated long-term clinical outcomes in patients with advanced renal dysfunction (eGFR < 30 mL/min/1.73 m2), focusing on 151 patients who underwent elective PCI and their long-term renal outcomes. Renal dysfunction progression was defined as a 20% relative decrease in eGFR at 1 year from baseline or the initiation of permanent dialysis within 1 year. Progression of renal dysfunction at 1 year occurred in 42 patients (34.1%). Among patients with renal dysfunction progression, the decrease of renal function from baseline was not observed at 1 month but after 6 months of the index PCI. Baseline eGFR and serum albumin level were significant predictors of renal dysfunction progression at 1 year. Among 111 patients who had not been initiated on dialysis within 1 year, those with renal dysfunction progression had a significantly higher incidence of dialysis initiation more than 1 year after the index PCI than those with preserved renal function (p < 0.001). Among patients with advanced renal dysfunction who underwent elective PCI, 34.1% showed renal dysfunction progression at 1 year. The decrease in renal function was not observed at 1 month but after 6 months of the index PCI in patients with renal dysfunction progression. Furthermore, patients with renal dysfunction progression had poorer long-term renal outcomes.

RESUMEN

Percutaneous coronary intervention for bifurcation lesions remains challenging, with there being several debatable issues, including the requirement for kissing balloon inflation (KBI). The objective of this study was to assess the clinical outcomes following single crossover stent implantation with KBI or sequential dilation alone. Data were examined for 255 non-left main bifurcation lesions (246 patients) treated with single crossover stent implantation, followed by side branch (SB) strut dilation with KBI (n = 74 lesions) or sequential dilation (n = 181 lesions) in three hospitals. Target lesion revascularization (TLR) was the primary endpoint. There was no significant difference in the pre-procedural reference diameter of both the main vessel (MV) and SB between the KBI and sequential dilation groups. However, MV post-dilation balloon size was smaller with lower pressure and post-procedural minimal lumen diameter was significantly smaller in the KBI group. During the median follow-up period of approximately 3 years, TLR incidence was significantly higher in the KBI group than in the sequential dilation group; in particular, the TLR rate at the distal MV was higher in the former. For bifurcation lesions treated with single crossover stent implantation, the TLR rate was higher after KBI than after sequential dilation; this was mainly due to higher revascularization in the distal MV. For bifurcation lesions treated with KBI, MV post-dilation balloon diameter tended to be smaller with lower pressure, which might lead to poorer stent expansion and a higher TLR rate.

RESUMEN

Reduced exercise capacity is known to be an important predictor of poor prognosis and disability in patients with cardiovascular diseases and chronic heart failure, and even members of the general population. However, data about exercise capacity assessed by cardiopulmonary exercise testing (CPX) in acute myocardial infarction (AMI) patients who underwent primary percutaneous coronary intervention (PCI) is scarce. Among 594 consecutive AMI patients who underwent primary PCI, we examined 136 patients (85.3% men, 64.9 ± 11.9 years) who underwent CPX during hospitalization for AMI. CPX was usually performed 5 days after the onset of AMI. Reduced exercise capacity was defined as peak VO2 ≤ 12. Clinical outcomes including all-cause death, myocardial infarction, and hospitalization due to heart failure were followed. Among 136 patients, reduced exercise capacity (peak VO2 ≤ 12) was seen in 38 patients (28%). Patients with reduced exercise capacity were older, more likely to have hypertension, and had lower renal function. In echocardiography, patients with reduced exercise capacity had higher E/e' and larger left atrial dimension. Multivariate logistic analysis showed that E/e' (OR 1.19, 95% CI 1.09-1.31, p < 0.001) was an independent predictor of reduced exercise capacity (peak VO2 ≤ 12). Median follow-up term was 12 months (IQR 9-22). The occurrence of composite endpoints of all-cause death, myocardial infarction, and hospitalization due to heart failure was significantly higher in patients with peak VO2 ≤ 12 than those with peak VO2 > 12 (p < 0.001). Reduced exercise capacity following primary PCI in AMI patients is associated with diastolic dysfunction and may lead to poorer clinical outcomes.

RESUMEN

BACKGROUND: An integrated backscatter (IB) intravascular ultrasound (IVUS) provides an information about tissue components and vulnerability of coronary plaques. The presence of vulnerable plaque in non-culprit lesion is associated with future clinical events. The purpose of this study was to assess the association between the characteristics of non-culprit left main coronary artery (LMCA) plaques evaluated by IB-IVUS and long-term clinical outcomes in patients undergoing percutaneous coronary intervention (PCI). METHODS: Among the patients who underwent non-LMCA PCI, we studied 366 patients with adequate LMCA IVUS images. Conventional and IB-IVUS analyses of the LMCA segment were performed. Lipid-rich large plaque was defined as the presence of both a lager plaque volume and a higher percentage of the lipid component than the obtained median values. Major adverse cardiovascular events (MACE) included cardiac death, myocardial infarction, and unplanned revascularization. RESULTS: The mean age of the patients was 68.5 ± 10.2 years, 79.8% were men. Median follow-up period was 6.0 years (IQR: 4.2-8.1 years). The incidence of MACE was significantly higher in patients with lipid-rich large plaques (P = .006). The incidence rates of cardiac death, myocardial infarction, and unplanned revascularization were significantly higher in patients with lipid-rich large plaques (P = .02, 0.004, and 0.02, respectively). Multivariate Cox regression analysis showed that the presence of a lipid-rich large plaque was significantly associated with MACE (HR: 1.74; 95%CI: 1.17-2.58; P = .006). CONCLUSION: The presence of lipid-rich large plaques in a non-culprit LMCA can be associated with the long-term MACE in patients who have undergone PCI.

RESUMEN

AIM: An inverse association between diabetes mellitus (DM) and aortic dilatation has recently been reported. However, little is known about the association between DM and the progression of aortic dilatation/calcification as atherosclerosis progresses. METHODS: We identified 216 patients who had undergone percutaneous coronary intervention (PCI) and abdominal computed tomography (CT) during the PCI and follow-up phases. The patients were classified into two groups: those with DM (DM+ group; n=107) and those without DM (DM- group; n=109). The infrarenal aortic diameter and aortic calcification index (ACI) were measured, and annual changes were calculated using measurement results obtained during the PCI and follow-up phases. RESULTS: Infrarenal aortic diameters were significantly shorter in the DM+ group than in the DM- group during the PCI phase, and no significant ACI differences were observed between the DM+ and DM- groups. The median duration between the PCI and follow-up phase CT was 3.0 years. The growth rate of the infrarenal aortic dilatation from the PCI phase in the DM+ group was similar to that in the DM- group. Annual ACI changes were significantly larger in the DM+ group than in the DM- group. Multivariate logistic regression analysis indicated that the prevalence of DM was an independent predictor of rapid aortic calcification progression (odds ratio: 2.51; 95% confidence interval: 1.23-5.14; p=0.01). CONCLUSION: Our findings suggest that DM negatively affects aortic dilatation during an earlier phase of atherosclerosis progression and positively affects the progression of aortic calcification in a later phase.

RESUMEN

Although chronic total occlusion (CTO) in non-infarct-related arteries (non-IRAs) negatively affects long-term mortality in patients with acute myocardial infarction (AMI) who are undergoing primary percutaneous coronary intervention (PCI), the prognostic impact of successful CTO-PCI has not been completely addressed. Among 1855 consecutive patients with AMI who underwent primary PCI, those who were treated for CTO with either PCI or medical therapy were included. We evaluated the association between recanalization of CTO and long-term cardiac mortality. Of the 172 included patients, 88 underwent CTO-PCI, and the procedures were successful in 65 patients. Thus, the successfully recanalized CTO (SR-CTO) group included 65 patients; and the no recanalized CTO (NR-CTO) group, 107 patients. During the follow-up, 72 patients died, and of whom 56 (77.8%) died because of cardiac causes. The cumulative 10-year, 30-day, and 30-day to 10-year incidences of cardiac mortality were lower in the SR-CTO group than in the NR-CTO group (19.0% vs. 51.9% p = 0.004; 4.6% vs. 14.0%, p = 0.05; 15.0% vs. 44.1%, p = 0.003, respectively). After adjusting for confounding factors, the benefits of SR-CTO for the 10-year cardiac mortality remained significant compared with those of NR-CTO (hazard ratio 0.37; 95% confidence interval 0.17-0.75; p = 0.004). In conclusion, patients with SR-CTO in non-IRAs after AMI was associated with reduced long-term cardiac mortality compared with those with NR-CTO.

RESUMEN

BACKGROUND: Although there are guidelines that recommend an early invasive strategy in patients with non-ST-elevation acute coronary syndrome (NSTE-ACS) and concomitant congestive heart failure (CHF), optimal timing of the invasive strategy remains controversial. METHODS: Among 2045 patients who were admitted owing to NSTE-ACS or CHF, 300 presented with NSTE-ACS and concomitant CHF. Of the 300 patients, we enrolled 160 patients for whom coronary angiography (CAG) during their hospital stay was planned at the time of admission; 64 of these patients were classified into the early invasive group (<24h) and 96 were classified to the delayed invasive group (≥24h). We evaluated the primary outcome which was defined as a composite of cardiac mortality, life-threatening arrhythmia, and non-fatal myocardial infarction (MI). RESULTS: The median time between presentation and CAG was 2h in the early invasive group and 240h in the delayed group. During follow-up, the primary outcome was significantly lower in the early invasive group [hazard ratio (HR), 0.52; 95% confidence interval (CI), 0.30-0.87; p=0.01]. After the adjustment of confounding factors, the primary outcome was significantly less frequent (HR, 0.44; 95% CI, 0.23-0.78; p=0.004) in the early invasive group compared to the delayed invasive group. CONCLUSIONS: The early invasive strategy was associated with a lower risk of the composite primary outcome in the long-term follow-up of patients with NSTE-ACS and concomitant CHF.

RESUMEN

Although postdischarge bleeding (PDB) is known to negatively affect long-term outcome in patients undergoing percutaneous coronary intervention (PCI) with antiplatelet therapy (APT), the prognostic importance of PDB in patients who require both oral anticoagulants (OACs) and APT has not been fully elucidated. Among 3718 consecutive patients who underwent PCI, 302 patients were treated with both OACs and APT. We evaluated the association between PDB and 3-year all-cause mortality, as estimated by a time-updated Cox proportional hazard regression model. We performed nearest-neighbor matching on the propensity score to adjust the differences in baseline characteristics. Among 302 patients treated with OACs and APT, PDB was observed in 98 patients at a median time of 239 days. Patients experienced PDB had significantly higher incidence of 3-year all-cause mortality in the overall cohort and 94 propensity-score-matched pairs (hazard ratio 6.21, 95% confidence interval 3.29-11.72, P < 0.0001; and hazard ratio 6.13, 95% confidence interval 2.68-14.02, P < 0.0001, respectively). The risk of subsequent mortality was the highest within 180 days after PDB (58.3% within 180 days and 75.0% within 1 year). In conclusion, PDB was significantly associated with long-term mortality in patients taking both OACs and APT after PCI.

RESUMEN

BACKGROUND: No standardized tool exists for weighting bleeding risk before selecting an antithrombotic regimen in patients undergoing percutaneous coronary intervention (PCI) who require both oral anticoagulant (OAC) and antiplatelet agents. METHODS: We performed PCI in 3718 consecutive patients between April 2011 and March 2017, 302 of whom were treated with both OAC and antiplatelet agents. We retrospectively evaluated the predictive performance of four major bleeding risk scores (HAS-BLED, ORBIT, PRECISE-DAPT, and PARIS score). Patients were followed for up to 3 years for bleeding events, defined as a composite of major and minor bleeding according to the Thrombolysis in Myocardial Infarction (TIMI) criteria and the Bleeding Academic Research Consortium (BARC) criteria. RESULTS: TIMI significant bleedings (major, minor, and requiring medical attention) were seen in 90 patients (29.8%); whereas the BARC class ≥3 bleedings were seen in 53 patients (17.5%). Regarding TIMI significant bleedings, HAS-BLED, ORBIT, and PRECISE-DAPT scores equally categorized high-risk patients, but the PARIS score could not [high-risk versus non-high-risk: hazard ratio (HR), 1.74; 95% confidence interval (CI), 1.15-2.64; p=0.01; HR, 1.63; 95% CI, 1.08-2.48; p=0.02; HR, 1.62; 95% CI, 1.06-2.51; p=0.03; HR, 1.05; 95% CI, 0.70-1.63; p=0.79, respectively); regarding BARC class ≥3 bleeding, all four scores could stratify high-risk patients (high-risk versus non-high-risk: HR, 2.23; 95% CI, 1.30-3.88; p=0.004; HR, 2.25; 95% CI, 1.31-3.96; p=0.003; HR, 3.87; 95% CI, 2.06-7.91; p<0.0001; HR, 1.85; 95% CI, 1.04-3.47; p=0.04, respectively). CONCLUSIONS: In patients taking an OAC undergoing PCI, HAS-BLED, ORBIT, and PRECISE-DAPT scores predicted TIMI significant bleeding events better than the PARIS score; whereas all four scores could predict BARC class ≥3 bleeding events.

RESUMEN

AIM: Patients undergoing percutaneous coronary intervention (PCI) who require both oral anticoagulant (OAC) and antiplatelet therapy (APT) are exposed to a serious risk of bleeding. The aim of this study was to clarify the relationship among nutritional and inflammation status and long-term bleeding in patients requiring both OACs and APT after PCI. METHODS: We performed PCI in 3,718 consecutive patients between April 2011 and March 2017, 302 of whom were treated with both OACs and APT. Patients were followed for up to 3 years for bleeding events, defined as the Bleeding Academic Research Consortium (BARC) class ≥3 bleeding. We retrospectively evaluated the ability of the Geriatric Nutritional Risk Index (GNRI) and high-sensitivity C-reactive protein (hs-CRP) to detect bleeding events. RESULTS: During a median follow-up of 1,080 days, bleeding events were observed in 53 (17.5%) patients. Bleeding events were associated with a low GNRI (≤98) (hazard ratio [HR], 3.16; 95% confidence interval [CI], 1.84-5.45; p＜0.0001) and hs-CRP level ≥2.5 mg/L (HR, 2.75; 95% CI, 1.61-4.78; p=0.0003). A low GNRI＋high hs-CRP showed a 5.12-fold increase in the incidence of BARC class ≥3 bleeding (95% CI, 2.68-9.91; p＜0.0001) compared with a normal GNRI＋low hs-CRP. The addition of the GNRI and hs-CRP to the PRECISE-DAPT score improved C-statistics from 0.67 to 0.71 and enhanced the net reclassification improvement (NRI) and integrated discrimination improvement (IDI) (NRI, 0.36, p＜0.0001; IDI, 0.066, p＜0.0001). CONCLUSIONS: The GNRI and hs-CRP were novel predictors of the long-term bleeding risk in patients requiring both OACs and APT after PCI.
