RESUMO
Background: Low-density lipoprotein cholesterol (LDL-C) is considered the most important risk factor for coronary artery disease (CAD). Although lipid-lowering therapy using high-intensity statins for patients with stable CAD is one of the cornerstones of medication therapy, there is still a risk of residual cardiovascular events, even after controlling for LDL-C. Recently, attention has focused on the association between small dense LDL-C as a residual risk factor for CAD, and it has been reported that a formula can be used to calculate the small LDL-C. Methods: We investigated the association between estimated small dense LDL-C (Esd LDL-C) and the occurrence of new lesions with myocardial ischemia ≤ 2 years after percutaneous coronary intervention (PCI) in 537 patients with stable angina who underwent PCI. In this study, all patients had been prescribed statins. This study was based on previously reported data regarding the relationship between non-high-density lipoprotein cholesterol levels and stable angina pectoris after PCI. Results: Revascularization, including new lesions and in-stent restenosis, and new lesions appeared in 130 and 90 patients, respectively, ≤ 2 years after PCI. Age, diabetes mellitus (DM), LDL-C, and Esd LDL-C were associated with the occurrence of revascularization and new lesions ≤ 2 years after PCI. Multivariate logistic regression analysis models revealed that Esd LDL-C [odds ratio (OR) 1.03, 95% confidence interval (CI) 1.004-1.048, p = 0.020; and OR 1.03, 95% CI 1.009-1.057, p = 0.007, respectively] were associated with the revascularization and occurrence of new lesions ≤ 2 years after PCI. Conclusions: As well as total cholesterol and LDL-C, Esd LDL-C was an independent risk factor for the revascularization and occurrence of new lesions ≤ 2 years after PCI for stable angina in Japanese patients receiving statin therapy. In patients with stable angina who are on lipid-lowering therapy with statins, calculating the Esd LDL-C may provide useful information for predicting revascularization and the occurrence of new lesions.
RESUMO
High bleeding risk (HBR), as defined by the Academic Research Consortium for High Bleeding Risk (ARC-HBR) criteria, has been recently reported to be associated with an increased risk of major bleeding events and cardiovascular events. We investigated the association between the ARC-HBR score and clinical outcomes in patients with stable coronary artery disease (CAD) who underwent percutaneous coronary intervention (PCI). We assessed 328 consecutive patients with stable CAD who underwent PCI between January 2017 and December 2020. We scored the ARC-HBR criteria by assigning 1 point to each major criterion and 0.5 points to each minor criterion. Patients were stratified into low (ARC-HBR score < 1), intermediate (1 ≤ ARC-HBR score < 2), and high (ARC-HBR score ≥ 2) bleeding-risk groups. The primary outcome measure was major adverse cardiovascular events (MACE), defined as a composite of all-cause death, nonfatal myocardial infarction, and nonfatal stroke. We compared the discriminative abilities of the ARC-HBR score with the Thrombolysis in Myocardial Infarction Risk Score for Secondary Prevention (TRS2°P) and ARC-HBR score with Coronary Revascularization Demonstrating Outcome Study in Kyoto (CREDO-Kyoto) thrombotic risk score. The mean patient age was 70.1 ± 10.2 years (males, 76.8%). During the median follow-up period of 983 (618-1338) days, 44 patients developed MACE. Kaplan-Meier curves showed that a stepwise significant increase in the cumulative incidence of MACE as the ARC-HBR score increased (log-rank p < 0.001). In the time-dependent receiver-operating characteristic curve analysis for predicting MACE within 2 years, the area under the curve (AUC) of the ARC-HBR score was significantly higher than that of the TRS2°P (AUC: 0.825 vs. 0.725, p value for the difference = 0.023) and similar to that of CREDO-Kyoto thrombotic risk score (AUC: 0.825 vs. 0.813, p value for the difference = 0.627). Conclusions: The ARC-HBR score adequately stratified future risk of MACE in patients with stable CAD who underwent PCI. The ARC-HBR score showed a higher discriminative ability for predicting mid-term MACE than the TRS2°P.
RESUMO
Background: This study aimed to compare the discriminative ability of the Japanese Version of High Bleeding Risk (J-HBR), Academic Research Consortium for High Bleeding Risk (ARC-HBR), and Predicting Bleeding Complications in Patients Undergoing Stent Implantation and Subsequent Dual Antiplatelet Therapy (PRECISE-DAPT) scores for predicting major bleeding events. MethodsâandâResults: Between January 2017 and December 2020, 646 consecutive patients who underwent successful percutaneous coronary intervention (PCI) were enrolled. We scored the ARC-HBR and J-HBR criteria by assigning 1 point to each major criterion and 0.5 point to each minor criterion. The primary outcome was major bleeding events, defined as Bleeding Academic Research Consortium type 3 or 5 bleeding events. According to the J-HBR, ARC-HBR, and PRECISE-DAPT scores, 428 (66.3%), 319 (49.4%), and 282 (43.7%) patients respectively had a high bleeding risk. During the follow-up period (median, 974 days), 44 patients experienced major bleeding events. The area under the curve (AUC) using the time-dependent receiver operating characteristic curve for major bleeding events was 0.84, 0.82, and 0.83 within 30 days and 0.86, 0.83, and 0.80 within 2 years for the J-HBR, ARC-HBR, and PRECISE-DAPT scores, respectively. The AUC values did not differ significantly among the 3 bleeding risk scores. Conclusions: The J-HBR score had a discriminative ability similar to the ARC-HBR and PRECISE-DAPT scores for predicting short- and mid-term major bleeding events.
RESUMO
BACKGROUND: Diabetes mellitus (DM) and hypertension are well-known atherosclerosis risk factors. Furthermore, renal dysfunction is a crucial risk factor for patients with coronary artery disease (CAD), and managing renal function in these patients is complicated because of comorbid conditions and potential side effects during treatment. Therefore, this study aimed to investigate the effect of medications for hypertension on renal function after percutaneous coronary intervention (PCI) between patients with and without DM with statins. METHODS: In 297 consecutive patients undergoing PCI for stable angina pectoris, cystatin C (CysC) was evaluated at baseline and 9 months after PCI, and the percent change in CysC (%CysC) was calculated. The association of worsening renal function (WRF: %CysC ≥ 0) and baseline characteristics, including medications, was assessed. RESULTS: Among 297 hypertensive patients with statins, 196 and 101 were with and without DM, respectively. Angiotensin-converting enzyme inhibitor (ACEI), angiotensin II receptor blocker, and ß-blocker were prescribed in 56 (29%), 82 (42%), and 91 (46%) patients in the DM group, and 20 (20%), 52 (51%), and 52 (51%) in the non-DM group, respectively. The patients with WRF after PCI were 100 (51%) and 59 (58%) in the DM and non-DM groups (p = 0.261). Additionally, the %CysC had no significant differences between groups [median: 0%, interquartile range (IQR): -7.9% to 8.5% vs. median: 1.1%, IQR: -6.6% to 9.6%, p = 0.521]. Multivariate logistic analysis for WRF using relevant factors from univariate analysis showed that only ß-blocker [odds ratio (OR): 2.76, 95% confidence interval (CI): 1.03-7.90, p = 0.048] was independently associated with WRF in the DM group whereas ACEI (OR: 0.07, 95% CI: 0.01-0.47, p = 0.012) was negatively correlated with WRF in the non-DM group. CONCLUSION: The ß-blocker was the independent risk factor for WRF in patients with DM in the late phase after PCI for stable angina pectoris, while the use of ACEI had a renoprotective effect in patients without DM.

BACKGROUND: Living alone as a proxy for social isolation has been considered to increase the risk of cardiovascular disease. We thus investigated the impact of living alone on mortality in acute myocardial infarction (AMI) patients. METHODS: Subjects comprised 277 AMI patients who underwent percutaneous coronary intervention (PCI). Associations between all-cause and cardiac deaths after PCI and baseline characteristics including living alone and Global Registry of Acute Coronary Events (GRACE) risk score were assessed. RESULTS: Eighty-three patients (30%) were living alone. Thirty patients died after PCI, including 20 cardiac deaths. Patients living alone showed higher incidences of both all-cause and cardiac deaths compared with patients not living alone (18% vs. 8%, P â =â 0.019 and 14% vs. 4%, P â =â 0.004). Multivariate Cox proportional hazards regression analysis models showed living alone [hazard ratio (HR), 2.60; 95% confidence interval (CI), 1.20-5.62; P â =â 0.016 and HR, 4.17; 95% CI, 1.60-10.84; P â =â 0.003] and GRACE risk score (HR, 1.02; 95% CI, 1.01-1.03; P â =â 0.003 and HR, 1.03; 95% CI, 1.01-1.04; P â <â 0.001) correlated significantly with all-cause and cardiac deaths. Cox proportional hazards modeling revealed that patients living alone with GRACE risk score ≥162 derived from the receiver-operating characteristic curve showed a significantly greater risk of all-cause death than patients not living alone with GRACE risk score <162 (HR 16.57; 95% CI 6.67-41.21; P â <â 0.001). CONCLUSION: Among AMI patients, living alone represents an independent risk factor for all-cause and cardiac deaths after PCI, separate from GRACE risk score. Furthermore, AMI patients living alone with high GRACE risk scores may experience an additively increased risk of mortality after PCI.

Elevation of the ST segment after percutaneous coronary intervention (PCI) using rotational atherectomy (RA) for severely calcified lesions often persists after disappearance of the slow-flow phenomenon on angiography. We investigated clinical factors relevant to prolonged ST-segment elevation following RA among 152 patients with stable angina undergoing elective PCI. PCI procedures were divided into two strategies, RA without (primary RA strategy) or with (secondary RA strategy) balloon dilatation before RA. Incidence of prolonged ST-segment elevation after disappearance of slow-flow phenomenon was higher in the 56 patients with primary RA strategy (13%) than in the 96 patients with secondary RA strategy (3%, p = 0.039). Univariate logistic regression analysis showed levels of low-density lipoprotein cholesterol (LDL-C) (odds ratio [OR] 0.95, 95% confidence interval [CI] 0.93-0.99; p = 0.013), levels of triglycerides (OR 0.97, 95%CI 0.94-0.99; p = 0.040), and secondary RA strategy (OR 0.23, 95% CI 0.05-0.85; p = 0.028) were inversely associated with occurrence of prolonged ST-segment elevation following ablation. However, hemodialysis, diabetes mellitus, left-ventricular ejection fraction, lesion length ≥ 20 mm, and burr size did not show significant associations. Multivariate logistic regression analysis modeling revealed that secondary RA strategy was significantly associated with the occurrence of prolonged ST-segment elevation (Model 1: OR 0.24, 95% CI 0.05-0.95, p = 0.042; Model 2: OR 0.17, 95% CI 0.03-0.68, p = 0.018; Model 3: OR 0.21, 95% CI 0.03-0.87, p = 0.041) even after adjusting for levels of LDL-C and triglycerides. Secondary RA strategy may be useful to reduce the occurrence of prolonged ST-segment elevation following RA.

There are few reports on the long-term clinical outcome after percutaneous coronary intervention (PCI) in patients with stable coronary artery disease (CAD) complicated with frailty. This novel study investigated the association between pre-PCI frailty and long-term clinical outcomes in elderly patients aged 65 years or older with stable CAD who underwent elective PCI. We assessed 239 consecutive patients aged 65 years or older with stable CAD who underwent successful elective PCI at Kagoshima City Hospital between January 1st, 2017 and December 31st, 2020. Frailty was retrospectively assessed using the Canadian Study and Aging Clinical Frailty Scale (CFS). Based on the pre-PCI CFS, patients were divided into two groups: the non-frail (CFS < 5) and the frail (CFS ≥ 5) group. We investigated the association between pre-PCI CFS and major adverse cardiovascular events (MACEs) defined as the composite of all-cause death, non-fatal myocardial infarction, non-fatal stroke, and heart failure requiring hospitalization. Additionally, we assessed the association between pre-PCI CFS and major bleeding events defined as Bleeding Academic Research Consortium (BARC) type 3 or 5 bleeding. The mean age was 74.8 ± 7.0 years, and 73.6% were men. According to the pre-PCI frailty assessment, 38 (15.9%) and 201 (84.1%) were classified as frail and non-frail groups, respectively. During a median follow-up of 962 (607-1284) days, 46 patients developed MACEs and 10 patients developed major bleeding events. Kaplan-Meier curves showed a significantly higher incidence of MACE in the frail group compared to those in the non-frail group (Log-rank p < 0.001). Even in multivariate analysis, pre-PCI frailty (CFS ≥ 5) was independently associated with MACE (HR 4.27, 95% CI 1.86-9.80, p-value: < 0.001). Additionally, the cumulative incidence of major bleeding events was significantly higher in the frail group than in the non-frail group (Log-rank p = 0.001). Pre-PCI frailty was an independent risk factor for MACE and bleeding events in elderly patients with stable CAD who underwent elective PCI.

We investigated dose perturbations caused by 125I seeds in patients undergoing supplemental external beam radiotherapy (EBRT) for prostate cancer. We examined two types of nonradioactive seed models: model 6711 and model STM1251. All experiments were performed using a water-equivalent phantom. Radiochromic film was used to measure the dose distributions adjacent to the seeds upstream and downstream of the external beam source. Single and clusters of multiple seeds were placed in slots in a solid water (SW) slab to measure dose perturbations with separate versus dense seed placement at beam energies of 6 or 10 MV. Monte Carlo simulations (MCSs) were also performed to include the theoretical basis against film dosimetry. Distinct patterns of dose enhancement (buildup [BU]) were upstream, and dose reduction (builddown [BD]) were downstream of the radiation source. Model 6711 with lower photon beam energies produced larger dose perturbations of BU and BD than the model STM1251. The results showed the same tendency with different seed placements and beam energies. However, these differences were not observed in the rotational irradiation measurement, which replicated a clinical plan. Dose perturbations around seeds result in dose enhancement and dose reduction with varying impact depending on the photon beam energy and seed type. This has the potential to cancel out these perturbations using multiple beam direction fields.
RESUMO
BACKGROUND: Academic Research Consortium for High Bleeding Risk (ARC-HBR) criteria have been used to identify high-risk patients undergoing percutaneous coronary intervention (PCI) in current clinical practice. This study aimed to evaluate the association between the number of ARC-HBR criteria and clinical outcomes in patients with acute coronary syndrome (ACS) after an emergent PCI. METHODS: We assessed 338 consecutive patients with ACS who underwent successful emergent PCI between January 2017 and December 2020. The ARC-HBR score was calculated by assigning 1 point to each major criterion and 0.5 points to each minor criterion. The patients were classified into low (ARC-HBR score<1), intermediate (1≤ARC-HBR score<2), and high (ARC-HBR score≥2) bleeding risk groups. We investigated the association between the ARC-HBR score and major adverse cardiovascular events (MACEs), defined as a composite of all-cause death, non-fatal myocardial infarction, and non-fatal stroke. We also compared the diagnostic ability of the ARC-HBR score and Controlled Abciximab and Device Investigation to Lower Late Angioplasty Complications (CADILLAC) risk score. RESULTS: The mean age of the patients was 67.6±12.4years, and 78.4% were men. During the median follow-up of 864 (557-1309) days, 70 patients developed MACEs. Kaplan-Meier curves showed that the cumulative incidence of MACE was significantly higher as the ARC-HBR score increased in a stepwise manner (log-rank p<0.001). There were no significant differences in the area under the receiver operating characteristic curve (AUC) for predicting MACE within two years after an emergent PCI between the ARC-HBR and CADILLAC risk scores (AUC: 0.763 vs. 0.777). CONCLUSIONS: ARC-HBR score was independently associated with an increased risk of MACE in patients with ACS after an emergent PCI. Moreover, it had a similar diagnostic ability for predicting MACE within two years compared to the CADILLAC risk score.

OBJECTIVE: The Wound, Ischemia, and foot Infection (WIfI) clinical stage has been thought to have a prognostic value in Chronic limb-threatening ischemia (CLTI) patients, and frailty and nutritional status appear to represent pivotal factor affecting prognosis among CLTI patients. The purpose of this study was to examine clinical factors (including frailty and nutritional status) relevant to WIfI clinical stage. METHODS: This retrospective study investigated 200 consecutive CLTI patients. We individually assessed WIfI clinical stage, frailty according to the Clinical Frailty Scale (CFS) score, and malnutrition according to Geriatric Nutritional Risk Index (GNRI). We then compared mortality after endovascular intervention between a WIfI stage 1, 2 group and a stage 3, 4 group, and investigated associations between baseline characteristics (including CFS and GNRI) and WIfI clinical stage. RESULTS: Among 200 patients, 123 patients (62%) showed WIfI stage 1 or 2, and the remaining 77 patients (38%) had WIfI stage 3 or 4. CFS score was significantly higher in the WIfI stage 3, 4 group [median 6.0, interquartile range (IQR) 5.5-7.0] compared with the WIfI stage 1, 2 group (median 5.0, IQR 4.0-6.0, p < 0.001), and GNRI was significantly lower in the WIfI stage 3, 4 group (median 88, IQR 80-97) than in the WIfI stage 1, 2 (median 103, IQR 94-111, p < 0.001). Forty patients (20%) died after endovascular intervention. Incidences of all-cause and cardiac deaths were higher in the WIfI stage 3, 4 group than in the WIfI stage 1, 2 group (27% vs. 15%, p = 0.047 and 12% vs. 3%, p = 0.040, respectively). Kaplan-Meier analysis showed a significantly lower survival rate in the WIfI stage 3, 4 group than in the WIfI stage 1, 2 group (p = 0.002 by log-rank test). Multivariate logistic regression analysis using relevant factors from univariate analysis showed CFS score [odds ratio (OR) 2.06, 95% confidence interval (CI) 1.41-3.13, p < 0.001), diabetes mellitus (OR 3.17, 95%CI 1.17-8.61, p = 0.023) and GNRI (OR 0.93, 95%CI 0.89-0.97, p = 0.002) significantly associated with WIfI stage 3 or 4. In addition, multivariate ordinal logistic regression analysis for WIfI clinical stage showed CFS score (OR 1.43, 95%CI 1.09-1.89, p = 0.011), diabetes mellitus (OR 1.77, 95%CI 1.26-2.54, p < 0.001), and high-sensitivity C-reactive protein (OR 1.14, 95%CI 1.02-1.28, p = 0.041) were positively associated with WIfI clinical stage, and GNRI correlated negatively with WIfI clinical stage (OR 0.95, 95%CI 0.91-0.97, p < 0.001). CONCLUSIONS: These results indicate that CLTI patients with high WIfI clinical stage may be more frail and malnourished, and be associated with poor prognosis after endovascular intervention.

Nutritional status is an important factor affecting prognosis of cardiovascular diseases. We compared major cardiovascular and cerebrovascular events (MACCE) between the malnutrition (geriatric nutritional risk index <92) and non-malnutrition (geriatric nutritional risk index ≥92) groups in 500 stable coronary artery disease patients undergoing percutaneous coronary intervention and evaluated coronary calcification by intravascular ultrasound. Incidences of all-cause death and MACCE differed between the malnutrition and non-malnutrition groups (22% vs 5%, P < 0.001 and 24% vs 6%, P < 0.001). In multivariate Cox proportional hazards regression, malnutrition significantly correlated with all-cause death (Pâ¯=â¯0.006) and MACCE (Pâ¯=â¯0.010). The proportion of moderate/severe calcification differed between the malnutrition (64%) and non-malnutrition groups (33%, P < 0.001). Multivariate logistic analysis identified age (P < 0.001), malnutrition (Pâ¯=â¯0.048), and hemodialysis (P < 0.001) as significantly related to moderate/severe calcification. Malnutrition was an independent risk factor for all-cause death and MACCE in coronary artery disease patients after percutaneous coronary intervention and was associated with moderately/severely calcified lesions.

BACKGROUND: Malnutrition affects the prognosis of cardiovascular disease. Acute myocardial infarction (AMI) has been a major cause of death around the world. Thus, we investigated the impact of malnutrition as defined by Geriatric Nutritional Risk Index (GNRI) on mortality in AMI patients. METHODS: In 268 consecutive AMI patients who underwent percutaneous coronary intervention (PCI), associations between all-cause death and baseline characteristics including malnutrition (GNRI < 92.0) and Global Registry of Acute Coronary Events (GRACE) risk score were assessed. RESULTS: Thirty-three patients died after PCI. Mortality was higher in the 51 malnourished patients than in the 217 non-malnourished patients, both within 1 month after PCI (p < 0.001) and beyond 1 month after PCI (p = 0.017). Multivariate Cox proportional hazards regression modelling using age, left ventricular ejection fraction and GRACE risk score showed malnutrition correlated significantly with all-cause death within 1 month after PCI (hazard ratio [HR] 7.04; 95% confidence interval [CI] 2.30-21.51; p < 0.001) and beyond 1 month after PCI (HR 3.10; 95% CI 1.70-8.96; p = 0.037). There were no significant differences in area under the receiver-operating characteristic (ROC) curve between GRACE risk score and GNRI for predicting all-cause death within 1 month after PCI (0.90 vs. 0.81; p = 0.074) or beyond 1 month after PCI (0.69 vs. 0.71; p = 0.87). Calibration plots comparing actual and predicted mortality confirmed that GNRI (p = 0.006) was more predictive of outcome than GRACE risk score (p = 0.85) beyond 1 month after PCI. Furthermore, comparison of p-value for interaction of malnutrition and GRACE risk score for all-cause death within 1 month after PCI, beyond 1 month after PCI, and the full follow-up period after PCI were p = 0.62, p = 0.64 and p = 0.38, respectively. CONCLUSIONS: GNRI may have a potential for predicting the mortality in AMI patients especially in beyond 1 month after PCI, separate from GRACE risk score. Assessment of nutritional status may help stratify the risk of AMI mortality.

AIM: In this study, we aim to examine the clinical meaning of low-density lipoprotein cholesterol (LDL-C) ï¼70 mg/dL as assessed by Friedewald equation [LDL-C (F)] and Martin method [LDL-C (M)] and non-high-density lipoprotein cholesterol (HDL-C) ï¼100 mg/dL on the occurrence of new lesions among Japanese patients with stable angina who underwent percutaneous coronary intervention (PCI) and were prescribed with strong statins. METHODS: Among the 537 consecutive stable angina patients who had underwent PCI and had been prescribed with strong statins, the association between the occurrence of new lesions with myocardial ischemia at the 9-month follow-up coronary angiography and ≤ 2 years after PCI and baseline characteristics were assessed. RESULTS: New lesions appeared 9 months and ≤ 2 years after PCI in 31 and 90 patients, respectively. Multivariate logistic regression analysis revealed diabetes mellitus (DM) was significantly associated with the occurrence of new lesions ≤ 2 years after PCI [odds ratio (OR) 1.71, 95 % confidence interval (CI) 1.06-2.83, p=0.031], and only non-HDL-C ≥ 100 mg/dL was associated with the occurrence of new lesions both at 9 months and ≤ 2 years after PCI [OR 1.80, 95 % CI 1.10-3.00, p=0.021 and OR 1.85, 95 % CI 1.13-3.07, p=0.016]. CONCLUSIONS: Non-HDL-C ≥ 100 mg/dL was determined to be the independent risk factor for the occurrence of new lesions 9 months and ≤ 2 years after PCI among stable angina patients with strong statins. Residual risk after PCI should be considered by assessing not only DM but also non-HDL-C beyond the scope of LDL-C-lowering therapy with strong statins.

BACKGROUND: Stable coronary artery disease (CAD) patients with myocardial damage have a poor prognosis compared to those without myocardial damage. Recently, malnutrition has been reported to affect the prognosis of cardiovascular diseases. However, the effects of malnutrition on prognosis of CAD patients with myocardial damage remains uncertain. We investigated the effects of malnutrition on prognosis of CAD patients with myocardial damage who received percutaneous coronary intervention (PCI). METHODS: Subjects comprised 241 stable CAD patients with myocardial damage due to myocardial ischemia or infraction. Patients underwent successful revascularization for the culprit lesion by PCI using second-generation drug-eluting stents and intravascular ultrasound. The geriatric nutritional risk index (GNRI), which is widely used as a simple method for screening nutritional status using body mass index and serum albumin, was used to assess nutritional status. Associations between major cardiovascular and cerebrovascular events (MACCE) and patient characteristics were assessed. RESULTS: Mean GNRI was 100 ± 13, and there were 55 malnourished patients (23%; GNRI < 92) and 186 non-malnourished patients (77%). MACCE occurred within 3 years after PCI in 42 cases (17%), including 34 deaths (14%), and the malnourished group showed a higher rate of MACCE (38%) compared with the non-malnourished group (11%, p < 0.001). Univariate Cox proportional hazards analyses showed that MACCE was associated with age [hazard ratio (HR), 1.04; 95% confidence interval (CI), 1.04-1.07; p = 0.004], prior heart failure (HR 2.35; 95% CI 1.10-5.01; p = 0.027), high-sensitivity C-reactive protein (HR 1.08; 95% CI 1.03-1.11; p < 0.001), hemodialysis (HR 2.63; 95% CI 1.51-4.58; p < 0.001) and malnutrition (HR 3.69; 95% CI 2.11-6.42; p < 0.001). Multivariate Cox proportional hazards analysis revealed hemodialysis (HR 2.17; 95% CI 1.19-3.93; p = 0.011) and malnutrition (HR 2.30; 95% CI 1.13-4.67; p = 0.020) as significantly associated with MACCE. Furthermore, Cox proportional hazards models using malnutrition and hemodialysis revealed that patients with malnutrition and hemodialysis were at greater risk of MACCE after PCI than patients with neither malnutrition nor hemodialysis (HR 6.91; 95% CI 3.29-14.54; p < 0.001). CONCLUSIONS: In CAD patients with myocardial damage, malnutrition (GNRI < 92) represents an independent risk factor for MACCE. Assessment of nutritional status may help stratify the risk of cardiovascular events and encourage improvements in nutritional status.

BACKGROUND: Axillary artery injury secondary to proximal humerus fracture is a rare but serious complication. The management of this injury has traditionally involved surgical treatment. CASE SUMMARY: A 66-year-old female with gait disturbance slipped and fell off her wheelchair at home. She presented to a local hospital with right shoulder pain and was subsequently urgently transferred to our hospital by helicopter because of suspicion of axillary artery injury. Computed tomography angiography revealed disruption of the right axillary artery. We decided to perform endovascular treatment instead of surgical treatment for axillary artery injury. However, since endovascular treatment via the right femoral artery was impossible, we performed bidirectional (right femoral and right brachial artery approaches) endovascular treatment. We expanded the occluded lesion using a 3.5 mm × 40 mm sized balloon and placed a 5.0 mm × 50 mm stent graft (Gore® Viabahn®) across the lesion. The final subclavian injection confirmed that distal flow to the brachial artery was preserved and that there was no leakage of contrast medium from the axillary artery. DISCUSSION: We performed endovascular treatment for axillary artery injury secondary to proximal humerus fracture. Although surgical repair is typically performed for this kind of injury, our experience suggests that endovascular treatment might be an option in patients with axillary artery injury.
RESUMO
BACKGROUND: Pericardiocentesis is frequently performed when fluid needs to be removed from the pericardial sac, for both therapeutic and diagnostic purposes, however, it can still be a high-risk procedure in inexperienced hands and/or an emergent setting. CASE PRESENTATION: A 78-year-old male made an emergency call complaining of the back pain. When the ambulance crew arrived at his home, he was in a state of shock due to cardiac tamponade diagnosed by portable echocardiography. The pericardiocentesis was performed using a puncture needle on site, and the patient was immediately transferred to our hospital by helicopter. Contrast-enhanced computed tomography showed a small protrusion of contrast media on the inferior wall of the left ventricle, suggesting cardiac rupture due to acute myocardial infarction. Emergency coronary angiography was then performed, which confirmed occlusion of the posterior descending branch of the left circumflex coronary artery. In addition, extravasation of contrast medium due to coronary artery perforation was observed in the acute marginal branch of the right coronary artery. We considered that coronary artery perforation had occurred as a complication of the pericardial puncture. We therefore performed transcatheter coil embolization of the perforated branch, and angiography confirmed immediate vessel sealing and hemostasis. After the procedure, the patient made steady progress without a further increase in pericardial effusion, and was discharged on the 50th day after admission. CONCLUSIONS: When performing pericardial drainage, it is important that the physician recognizes the correct procedure and complications of pericardiocentesis, and endeavors to minimize the occurrence of serious complications. As with the patient presented, coil embolization is an effective treatment for distal coronary artery perforation caused by pericardiocentesis.

BACKGROUND: Proton pump inhibitors (PPIs) are known to increase the risk of mortality and cardiovascular events in the general population. However, in patients with maintenance hemodialysis, PPI effects are under investigated. METHODS: We analyzed the risk of PPIs for cardiovascular events using the Kagoshima Dialysis (KIDS) registry, a prospective, multicenter, observational study in patients with maintenance hemodialysis in Japan. RESULTS: In all, 531 patients were enrolled from June 2015 to December 2018. One-year follow-up data were available for 376 patients (Use of PPIs at baseline (PPI group): 217 patients and without PPIs (No PPI group): 159 patients). The incidence of a composite outcome (all-cause mortality, non-fatal myocardial infarction, or non-fatal stroke) was higher in patients in the PPI group than the No PPI group (15.2% vs. 4.4%; hazard ratio (HR): 3.65, 95% confidence interval (CI): 1.61-8.23, Pâ¯=â¯0.002). In the multivariate analysis, even after adjustment for covariates, the use of PPIs was an independent risk factor for a composite outcome (HR: 2.38, 95% CI: 1.02-5.54, Pâ¯=â¯0.045). We performed propensity score matching analysis as a sensitivity analysis, showing a consistent result. The incidence of bleeding showed no difference between the two groups (15.7% vs. 11.3%; HR: 1.46, 95% CI: 0.83-2.59, Pâ¯=â¯0.19). CONCLUSIONS: These results indicate that the use of PPIs in patients with maintenance hemodialysis might increase mortality and cardiovascular events without decreasing the risk of bleeding. Therefore, it should always be analyzed if a patient truly needs PPIs.

Background: Critical limb ischemia (CLI) patients have high risk for major adverse cerebrovascular and cardiovascular events. This study investigated the risk factors of cerebrovascular or cardiovascular death in CLI patients with concomitant coronary artery disease (CAD). MethodsâandâResults: The association between baseline characteristics and cerebrovascular or cardiovascular death ≤2 years after revascularization for CLI was investigated in 137 CLI patients who previously underwent successful revascularization for CAD before treatment for CLI. Twenty-three patients (17%) died. Geriatric nutritional risk index (GNRI) in the deceased group (DG) was significantly lower than in the surviving group (SG). On Cox proportional hazard multivariate analysis, hemodialysis (HD) and malnutrition (defined as GNRI <92) were significantly associated with cerebrovascular or cardiovascular death. Also, on Kaplan-Meier analysis, survival rate was significantly lower in CLI patients with either malnutrition or HD compared with patients without either malnutrition or HD, respectively. Furthermore, clopidogrel was less used in the DG than in the SG. The use of clopidogrel was associated with cerebrovascular or cardiovascular death. Especially, non-use of clopidogrel in the malnutrition group further increased the correlation with cerebrovascular or cardiovascular death. Conclusions: Malnutrition is a crucial risk factor for cerebrovascular and cardiovascular death in CLI patients with CAD. Nutritional status intervention and use of clopidogrel may be an important strategy for CLI.
