RESUMO
BACKGROUND: Hyperpolypharmacy is associated with adverse outcomes in older adults, but because literature on its association with cardiovascular (CV) outcomes after acute decompensated heart failure (ADHF) is sparse, we investigated the relationships among hyperpolypharmacy, medication class, and death in patients with HF.MethodsâandâResults: We evaluated the total number of medications prescribed to 884 patients at discharge following ADHF. Patients were categorized into nonpolypharmacy (<5 medications), polypharmacy (5-9 medications), and hyperpolypharmacy (≥10 medications) groups. We examined the relationship of polypharmacy status with the 2-year mortality rate. The proportion of patients taking ≥5 medications was 91.3% (polypharmacy, 55.3%; hyperpolypharmacy, 36.0%). Patients in the hyperpolypharmacy group showed worse outcomes than patients in the other 2 groups (P=0.002). After multivariable adjustment, the total number of medications was significantly associated with an increased risk of death (hazard ratio [HR] per additional increase in the number of medications, 1.05; 95% confidence interval [CI], 1.01-1.10; P=0.027). Although the number of non-CV medications was significantly associated with death (HR, 1.07; 95% CI, 1.02-1.13; P=0.01), the number of CV medications was not (HR, 1.01; 95% CI, 0.92-1.10; P=0.95). CONCLUSIONS: Hyperpolypharmacy due to non-CV medications was associated with an elevated risk of death in patients after ADHF, suggesting the importance of a regular review of the prescribed drugs including non-CV medications.

BACKGROUND: Acute decompensated heart failure (ADHF) has a poor prognosis and common comorbidities may be contributory. However, evidence for the association between dementia and clinical outcomes in patients with is sparse and it requires further investigation into risk reduction.MethodsâandâResults: We assessed the clinical profiles and outcomes of 1,026 patients (mean age 77.8 years, 43.2% female) with ADHF enrolled in the CURE-HF registry to evaluate the relationship between investigator-reported dementia status and clinical outcomes (all-cause death, cardiovascular (CV) death, non-CV death, and HF hospitalization) over a median follow-up of 2.7 years. In total, dementia was present in 118 (11.5%) patients, who experienced more drug interruptions and HF admissions due to infection than those without dementia (23.8% vs. 13.1%, P<0.01; 11.0% vs. 6.0%, P<0.01, respectively). Kaplan-Meier analysis revealed that dementia patients had higher mortality rates than those without dementia (log-rank P<0.001). After multivariable adjustment for demographics and comorbidities, dementia was significantly associated with an increased risk of death (adjusted hazard ratio, 1.43; 95% confidence interval, 1.06-1.93, P=0.02) and non-CV death (adjusted hazard ratio, 1.65; 95% confidence interval, 1.04-2.62, P=0.03), but no significant associations between dementia and CV death or HF hospitalization were observed (both, P>0.1). CONCLUSIONS: In ADHF patients dementia was associated with aggravating factors for HF admission and elevated risk of death, primarily non-CV death.

Peripheral artery disease (PAD) is commonly caused by atherosclerosis and has an unfavorable prognosis. Complete revascularization (CR) of the coronary artery reduces the risk of major adverse cardiovascular event (MACE) in patients with coronary artery disease (CAD). However, the impact of CR in patients with PAD has not been established to date. Therefore, we evaluated the impact of CR of CAD on the five-year clinical outcomes in patients with PAD. This study was based on a prospective, multicenter, observational registry in Japan. We enrolled 366 patients with PAD undergoing endovascular treatment. The primary endpoint was MACE, defined as a composite of all-cause death, non-fatal myocardial infarction, and non-fatal stroke. After excluding ineligible patients, 96 and 68 patients received complete revascularization of the coronary artery (CR group) and incomplete revascularization of the coronary artery (ICR group), respectively. Freedom from MACE in the CR group was significantly higher than in the ICR group at 5 years (66.7% vs 46.0%, p < 0.01). Multivariate analysis revealed that CR emerged as an independent predictor of MACE (Hazard ratio: 0.56, 95% confidential interval: 0.34-0.94, p = 0.03). CR of CAD was significantly associated with improved clinical outcomes in patients with PAD undergoing endovascular treatment.

BACKGROUND: Patients with critical limb ischemia (CLI) still have a high rate of lower limb amputation, which is associated with not only a decrease in quality of life but also poor life prognosis. Implantation of adipose-derived regenerative cells (ADRCs) has an angiogenic potential for patients with limb ischemia. OBJECTIVES: We investigated safety, feasibility, and efficacy of therapeutic angiogenesis by cell transplantation (TACT) of ADRCs for those patients in multicenter clinical trial in Japan. METHODS: The TACT-ADRC multicenter trial is a prospective, interventional, open-labeled study. Patients with CLI (Fontaine class III-IV) who have no other option for standard revascularization therapy were enrolled in this study. Thirty-four target ischemic limbs of 29 patients were received freshly isolated autologous ADRCs implantation. RESULTS: The overall survival rate at a post-operative period and at 6 months follow-up was 100% at any time points. As a primary endpoint for efficacy evaluation, 32 limbs out of 34 (94.1%) were free from major amputation for 6 months. Numerical rating scale (from 6 to 1) as QOL score, ulcer size (from 317 mm2 at to 109 mm2), and 6-min walking distance (from 255 to 369 m) improved in 90.6%, 83.3%, and 72.2% patients, respectively. CONCLUSIONS: Implantation of autologous ADRCs could be safe and effective for the achievement of therapeutic angiogenesis in the multicenter settings, as a result in no major adverse event, optimal survival rate, and limb salvage for patients with no-conventional option against critical limb ischemia.

PURPOSE: Information on the relationship between frailty and the outcome of endovascular therapy (EVT) in elderly patients with lower extremity peripheral artery disease (PAD) is scarce. This study aimed to reveal the impact of frailty on the prognosis of super-elderly patients who underwent EVT. MATERIALS AND METHODS: From August 2015 to August 2016, 335 consecutive patients who underwent EVT were enrolled in the I-PAD registry from 7 institutes in Nagano prefecture. Among them, we categorized 323 patients into 4 groups according to age and the presence or absence of frailty as follows: elderly with frailty (age ≥ 75, Clinical Frailty Scale [CFS] ≥ 5), elderly without frailty (age ≥ 75, CFS ≤ 4), young with frailty (age < 75, CFS ≥ 5), and young without frailty (age < 75, CFS ≤ 4); we analyzed them accordingly. The primary endpoints were major adverse cardiovascular and limb events (MACLE), defined as a composite of cardiovascular death, myocardial infarction, stroke, admission for heart failure, major amputation, and revascularization. The secondary endpoint was cardiovascular death. RESULTS: The median follow-up period was 2.7 years. In the elderly with frailty, elderly without frailty, young with frailty, and young without frailty groups, the freedom rates from MACLE were 34.9%, 55.7%, 35.4%, and 63.0%, respectively (p<0.001) and from all-cause death were 43.5%, 73.4%, 50.7%, and 90.9%, respectively (p<0.001). The freedom rates from MACLE were significantly higher among elderly patients with frailty than among young patients without frailty (55.7% vs 35.4%, p=0.01). In multivariate analysis, frailty was independently associated with MACLE incidence. CONCLUSION: Frailty as defined by CFS might be a predictor of MACLE incidence in patients with PAD who underwent EVT. By considering treatment indications for patients with PAD by focusing on frailty rather than age, we may examine whether EVT policies are appropriate and manage patient and caregiver expectations for potential improvement in functional outcomes. Further studies are expected to investigate whether changes in frailty after EVT change prognosis.

Laser speckle flowgraphy (LSFG) is a new device that can measure skin blood flow and capture the movement of erythrocytes. However, there are a few reports on the use of LSFG to estimate skin blood flow, especially in the lower extremities. We aimed to compare plantar skin blood flow between patients with and without peripheral arterial disease (PAD) to discern the extent to which LSFG could accurately predict PAD. We prospectively measured the plantar skin blood flow in 28 patients with PAD and 37 participants without PAD at two hospitals from 2017 to 2021, using the ankle-brachial index (ABI) and LSFG. We partitioned the plantar into 12 parts: digits 1-5, medial metatarsal, middle metatarsal, lateral metatarsal, medial arch, middle arch, lateral arch, and heel, and compared the difference between the two groups and the area under the curve (AUC) of each point. Statistical analyses were performed to determine the sensitivity, specificity, false-positive rate, and false-negative rate at high accuracy points of AUC and ABI. There was a significant difference among the 12 points between the two groups, and the ratio using toe 1 and toe 5 was highly accurate. The ratio using toe 1 indicated higher sensitivity (89 vs. 82%), higher false-positive rate (22 vs. 4%), lower specificity (81 vs. 97%), and an equivalent false-negative rate (9 vs. 12%) to that of the ABI. These findings could facilitate the use of LSFG to estimate the skin blood flow condition in the plantar skin. Our results indicate that measuring toe 1 using LSFG could be used to somewhat assess PAD.

Significant improvements in percutaneous coronary intervention (PCI) technology have enabled cardiovascular procedures to be performed without onsite cardiac surgery facilities. However, little is known about the association between onsite cardiac surgical support and long-term outcomes of PCI, particularly among emergent and complex cases. We investigated whether the presence or absence of cardiovascular surgery affects the long-term prognosis after PCI, emergent and complex elective cases. The SHINANO 5-year registry, a prospective, observational, and multicenter cohort study registry in Nagano, Japan, consecutively included 1665 patients who underwent PCI between August 2012 and July 2013. The procedures were performed at 11 hospitals with onsite cardiac surgery facilities [onsite surgery (+) group; n = 1257] and 8 hospitals without onsite cardiac surgery facilities [onsite surgery (-) group; n = 408]. The primary endpoint was all-cause mortality and the secondary endpoint was major adverse cardiac and cerebrovascular events [MACCE: all-cause death, Q-wave myocardial infarction, non-fatal stroke, and target lesion revascularization]. The onsite surgery group (+) had a lower rate of emergent PCI and ST-segment elevation myocardial infarction (40.8% vs. 51.7%, p < 0.01 and 24.9% vs. 39.2%, p < 0.01, respectively), and a higher prevalence of hemodialysis and history of peripheral artery disease (7.6% vs. 2.45%, p < 0.01 and 12.1% vs. 6.9%, p < 0.01, respectively). However, the Kaplan-Meier analysis showed no difference in the 5-year mortality rate (16.4% vs. 15.2%, p = 0.421) and MACCE incidence (31.6% vs. 28.9%, p = 0.354) between the groups. Also, there were no differences in the mortality rate and incidence of MACCE among emergent cases of ST-segment elevation myocardial infarction and complex elective cases who underwent PCI. Long-term outcomes of PCI appear to be comparable between institutions with and without onsite cardiac surgical facilities.

Endovascular treatment (EVT) is the main treatment for peripheral artery disease (PAD). Despite advances in device development, the restenosis rate remains high in patients with femoropopliteal lesions (FP). This study aimed to evaluate the effectiveness of exercise training in reducing the 1-year in-stent restenosis rate of bare metal nitinol stents for FPs. This prospective, randomized, open-label, multicenter study was conducted from January 2017 to March 2019. We randomized 44 patients who had claudication with de novo stenosis or occlusion of the FP into an intensive exercise group (n = 22) and non-intensive exercise group (n = 22). Non-intensive exercise was defined as walking for less than 30 min per session, fewer than three times a week. We assessed exercise tolerance using an activity meter at 1, 3, 6, and 12 months, and physiotherapists ensured maintenance of exercise quality every month. The primary endpoint was instant restenosis defined as a peak systolic velocity ratio > 2.5 on duplex ultrasound imaging. Kaplan-Meier analysis was used to evaluate the data. There were no significant differences in background characteristics between the groups. Six patients dropped out of the study within 1 year. In terms of the primary endpoint, intensive exercise significantly improved the patency rate of bare nitinol stents at 12 months. The 1-year freedom from in-stent restenosis rates were 81.3% in the intensive exercise group and 47.6% in the non-intensive exercise group (p = 0.043). No cases of stent fracture were observed in the intensive exercise group. Intensive exercise is safe and reduces in-stent restenosis in FP lesions after endovascular therapy for PAD. Clinical trial registration: University Hospital Medical Information Network Clinical Trials Registry (No. UMIN 000025259).

The optimal strategy for percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS) with multi-vessel disease (MVD) is still controversial. Residual anatomical features alone are not sufficient to appropriately stratify patient risk. Our aim was to assess the effectiveness of the residual Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score (rSS) combined with clinical factors to predict long-term clinical outcomes in ACS patients. A total of 120 patients with ACS and MVD undergoing PCI were recruited from the SHINANO 5-year registry: a prospective, multi-center, cohort study. The rSS combined with clinical factors (Combined Score) were calculated based on the residual coronary angiogram and each clinical feature after primary PCI. The Combined Score was calculated by replacing SS with rSS using the SYNTAX score II (SSII) calculator. We grouped the Combined Score in two groups according to the cut-off value calculated by the ROC curve (the C-statistic was 0.82 [95% CI 0.74-0.91]) for all-cause mortality. The primary endpoint was all-cause mortality during the 5-year follow-up. The Combined Score was associated with long-term mortality in Cox-regression analysis (HR 1.08, 95% CI 1.05-1.11, P < 0.001). The mortality rate was significantly higher in the high-score group compared with the low-score group (5.7% vs 38.0%; P < 0.001). In ACS with MVD, the Combined Score might be considered an important tool to predict long-term mortality following PCI.

Nutritional status is a novel approach to prognostic assessment in patients with cardiovascular disease. However, assessment of nutritional status in elderly patients is challenging due to the significant differences between young patients. The TCBI (Triglycerides × Total cholesterol × Body Weight Index) is a novel and simple nutritional index for predicting long-term outcomes in patients with coronary artery disease. This retrospective study evaluated the efficacy of TCBI in 597 elderly (≥ 75 years) patients enrolled in the SHINANO 5 year registry. The SHINANO 5 year registry, a prospective observational multicenter cohort study, had enrolled 1501 consecutive patients who underwent elective/urgent percutaneous coronary intervention (PCI). In this study, patients were categorized into TCBI quartile groups. The primary endpoints were the occurrence of major adverse cardiac and cerebrovascular events (MACCE), including all-cause death, stroke, and myocardial infarction at 5 year. The mean duration of follow up was 4.3 ± 1.7 years. The average patient age was 80.9 ± 4.3 years. MACCE was observed in 61 (40.9%) patients in the lowest TCBI quartile group. Kaplan-Meier analysis demonstrated an inverse relationship between MACCE and TCBI (log-lank P < 0.001). Multivariate analysis demonstrated that low TCBI significantly predicted the incidence of MACCE (hazard ratio: 1.44, 95% confidence interval: 1.03-2.00; P = 0.031). The TCBI is useful in predicting long-term outcomes in elderly patients undergoing PCI.

An inverse correlation between body mass index and mortality in patients with peripheral artery disease (PAD) has been reported. However, little information is available regarding the impact of body composition on the clinical outcomes in patients with PAD. This study evaluated the relationships between the lean body mass index (LBMI), body fat % (BF%), and mortality and major amputation rate in patients with PAD. We evaluated 320 patients with PAD after endovascular treatment (EVT) enrolled from August 2015 to July 2016 and divided them into low and high LBMI and BF% groups based on their median values (17.47 kg/m2 and 22.07%, respectively). We assessed 3-year mortality and major amputation for the following patient groups: Low LBMI/Low BF%, Low LBMI/High BF%, High LBMI/Low BF%, and High LBMI/High BF%. During the median 3.1-year follow-up period, 70 (21.9%) patients died and 9 (2.9%) patients experienced major amputation. The survival rate was lower in the Low LBMI than in the High LBMI group, and was not significantly different between the Low and High BF% groups. Survival rates were lowest in the Low LBMI/Low BF% group (57.5%) and highest in the High LBMI/High BF% group (94.4%). There were no significant differences in major amputation rate between the Low LBMI and High LBMI groups, and between the Low BF% and High BF% groups. The Low LBMI and Low BF% groups were associated with an increased risk of mortality after adjustment for age, sex, frailty and conventional risk factors [hazard ratio (HR): 4.02; 95% confidence interval (CI) 2.10-7.70; p < 0.001 and HR: 4.48; 95% CI 1.58-12.68, p = 0.005, respectively], for age, sex, hemodialysis, and prior cerebral cardiovascular disease (HR: 3.63; 95% CI 1.93-6.82; p < 0.001 and HR: 4.03; 95% CI 1.43-11.42, p = 0.009, respectively) and for age, sex, and laboratory date (HR: 3.97; 95% CI 1.88-8.37; p < 0.001 and HR: 3.31; 95% CI 1.15-9.53, p = 0.026, respectively). In conclusion, Low LBMI and Low BF% were associated with poor prognosis in patients undergoing EVT for PAD, and mortality was the lowest in the High LBMI/High BF% group compared with other body composition groups.

OBJECTIVES: Laser speckle flowgraphy is a technology using reflected scattered light for visualization of blood distribution, which can be used to measure relative velocity of blood flow easily without contact with the skin within a short time. It was hypothesized that laser speckle flowgraphy may be able to identify foot ischemia. This study was performed to determine whether laser speckle flowgraphy could distinguish between subjects with and without peripheral arterial disease. MATERIALS AND METHODS: All subjects were classified based on clinical observations using the Rutherford classification: non-peripheral arterial disease, class 0; peripheral arterial disease group, class 2-5. Rutherford class 6 was one of the exclusion criteria. Laser speckle flowgraphy measured the beat strength of skin perfusion as an indicator of average dynamic cutaneous blood flow change synchronized with the heartbeat. The beat strength of skin perfusion indicates the strength of the heartbeat on the skin, and the heartbeat strength calculator in laser speckle flowgraphy uses the blood flow data to perform a Fourier transform to convert the temporal changes in blood flow to a power spectrum. A total of 33 subjects with peripheral arterial disease and 40 subjects without peripheral arterial disease at a single center were prospectively examined. Laser speckle flowgraphy was used to measure hallucal and thenar cutaneous blood flow, and the measurements were repeated three times. The hallucal and thenar index was defined as the ratio of beat strength of skin perfusion value on hallux/beat strength of skin perfusion value on ipsilateral thenar eminence. The Mann-Whitney U-test was used to compare the median values of hallucal and thenar index and ankle brachial index between the two groups. A receiver operating characteristic curve for hallucal and thenar index of beat strength of skin perfusion was plotted, and a cutoff point was set. The correlation between hallucal and thenar index of beat strength of skin perfusion and ankle brachial index was explored in all subjects, the hemodialysis group, and the non-hemodialysis (non-hemodialysis) group. RESULTS: The median value of the hallucal and thenar index of beat strength of skin perfusion was significantly different between subjects with and without peripheral arterial disease (0.27 vs. 0.87, respectively; P < 0.001). The median value of ankle brachial index was significantly different between subjects with and without peripheral arterial disease (0.8 vs. 1.1, respectively; P < 0.001). Based on the receiver operating characteristic of hallucal and thenar index, the cutoff was 0.4416 and the sensitivity, specificity, positive predictive value, and negative predictive value were 68.7%, 95%, 91.7%, and 77.6%, respectively. The correlation coefficients of all subjects, the hemodialysis group, and the non-hemodialysis group were 0.486, 0.102, and 0.743, respectively. CONCLUSIONS: Laser speckle flowgraphy is a noninvasive, rapid, and widely applicable method. Laser speckle flowgraphy using hallucal and thenar index would be helpful to determine the differences between subjects with and without peripheral arterial disease. The correlation between hallucal and thenar index of beat strength of skin perfusion and ankle brachial index indicated that this index was especially useful in the non-hemodialysis group.

PURPOSE: To determine whether limb-based patency (LBP) after infrainguinal revascularization for chronic limb-threatening ischemia (CLTI) is similar between bypass surgery and endovascular therapy (EVT). MATERIALS AND METHODS: The database for the Surgical Reconstruction vs Peripheral Intervention in Patients With Critical Limb Ischemia (SPINACH) study was interrogated to identify 130 patients (mean age 73±8 years; 94 men) who underwent bypass surgery and 271 patients (mean age 74±10 years; 178 men) who underwent EVT alone. Skin perfusion pressure (SPP) and the ankle-brachial index (ABI) were measured before the procedure and at 0, 1, and 3 months after revascularization. The outcome measure was hemodynamically evaluated LBP (SPP ≥10 mm Hg or ABI ≥0.1) maintained over the first 3 months after treatment. Any reintervention or major amputation was regarded as loss of LBP. The associations between the revascularization strategy (bypass vs EVT) and between the preoperative characteristics and the study outcome (ie, SPP- or ABI-based LBP), were determined using generalized linear mixed models with a logit link function. Patency rates are presented with the 95% confidence interval (CI). RESULTS: The bypass surgery group had a higher stage of limb severity (WIfI) and anatomic complexity (GLASS) than the EVT group, whereas the EVT group had a higher prevalence of heart failure. Both SPP- and ABI-based LBP rates were higher in the bypass group than in the EVT group. SPP-based LBP rates at 3 months were 73.8% (95% CI 63.4% to 84.2%) in the bypass group and 46.2% (95% CI 38.5% to 53.8%) in the EVT group; the corresponding ABI-based LBP rates were 71.5% (95% CI 61.8% to 81.2%) and 44.0% (95% CI 37.3% to 50.7%). CONCLUSION: LBP is an important concept in the new global vascular guidelines for assessing the anatomic and hemodynamic status of CLTI patients. The present study found that LBP was significantly lower in the EVT group vs the bypass surgery group.

Little is known about the impact of changes in body mass index (BMI) after the percutaneous coronary intervention (PCI) on long-term outcomes in patients with coronary artery disease (CAD). Therefore, this study aimed to clarify this issue. We investigated data on CAD obtained from the SHINANO Registry, a prospective, observational, multicenter cohort study, from 2012 to 2013 in Nagano, Japan. One year after PCI, the enrolled patients were divided into the following three groups based on changes in BMI by tertiles: reduced, maintained, and elevated BMI. The associations among the groups and the 4-year outcomes [major adverse cardiac events (MACEs), all-cause death, Q-wave myocardial infarction, and stroke] were examined. Five hundred seventy-two patients were divided into the reduced, maintained, and elevated BMI groups. Over the 4-year follow-up period, the cumulative incidence of MACEs was 10.5% (60 cases). In the Kaplan-Meier analysis, the incidence rates of MACE were significantly higher in the reduced BMI group than in the maintained and elevated BMI groups [17.7% versus (vs.) 7.3% vs. 9.0%, p = 0.004]. Multivariable cox regression analysis showed that the reduced group showed increased risks of MACEs (hazard ratio 2.15; 95% confidence interval 1.29-3.57; p = 0.003). The long-term clinical outcomes of patients with CAD who underwent PCI were affected by the reduction in BMI after PCI. Furthermore, the elevation of BMI after PCI was not a poor prognostic factor.

OBJECTIVES: To evaluate the predictors of non-healing in patients with critical limb ischemia (CLI) after successful endovascular therapy (EVT). BACKGROUND: Occasionally, wound healing in patients with CLI and tissue loss cannot be achieved even after successful EVT. Patient's co-morbidities, vascular anatomy, wound features, and interventional strategies/outcomes are associated with the probability of wound healing. METHODS: Between April 2007 and October 2012, 182 patients with CLI (220 limbs) with tissue loss were treated with EVT in our institute. Of these, 164 individual wounds (130 patients, 149 limbs) out of 243 individual wounds were successfully treated. Successful EVT was defined as revascularization by achieving visible blood flow to the wounds, as evaluated by digital subtraction angiography performed just after EVT. A Cox proportional hazards model was used to analyze predictors associated with wound healing. RESULTS: The mean follow-up period was 23±18 months. The wound healing rates were 40.2%, 57.3%, 62.2%, and 70.7% at 3, 6, 9, and 12 months, respectively. Multivariate Cox proportional hazards analysis revealed that insulin use [hazard ratio (HR), 0.541; 95% confidence interval (CI), 0.329-0.890; P=0.016], dependence on hemodialysis [HR, 0.429; 95% CI, 0.272-0.678; P<0.001], and major tissue loss [HR, 0.460; 95% CI, 0.294-0.720; P=0.001] were independent predictors of non-healing after successful EVT. CONCLUSIONS: Insulin use, dependence on hemodialysis, and major tissue loss were independent predictors of non-healing after successful EVT.

PURPOSE: To examine the effectiveness of vascular elastography (VE) for the assessment of totally occluded lower limb arteries prior to endovascular treatment (EVT). METHODS: Of 812 consecutive patients who underwent EVT between April 2010 and April 2012, VE was used to evaluate the hardness of chronic total occlusions of the femoropopliteal segment prior to EVT in 65 consecutive patients (48 men; mean 73.9 years, range 63-86). Elastograms of the CTOs proximally and distally were scored using a 5-point scale, and outcomes in limbs with hard lesions (VE score 0-2) were compared to those with soft lesions (VE score 3-4) according to lesion length. The interventionists who performed the endovascular procedures were not informed of the VE score results. RESULTS: CTO characteristics could be evaluated in all cases. A VE score ≤2 was found in 14 of the 23 lesions <150 mm in length. A flexible guidewire was sufficient for recanalization in more of the soft lesions than in the hard lesions [6/9 vs. 2/14, respectively]. In 39 lesions >150 mm, a VE score of 3 was recorded in most lesions proximally, while lesions distally were hard in many cases (VE score 1 or 2). A flexible guidewire alone was sufficient in many soft CTOs (8/13, p<0.01). In 16 cases, hard calcified plaque was indicated by difficulty in penetrating the lesion even with a stiff guidewire; all these cases had a VE score of 1 or 2. A retrograde approach was required only in hard CTOs (p<0.01). The procedure time was significantly longer for the hard lesion group (152.9±63.2 vs. 87.0±29.8 minutes, p=0.001). In 11 in-stent occlusions, only VE scores of 3 (n=4) or 4 (n=7) were recorded, indicating soft thrombus, which was aspirated under distal protection in 7 cases. CONCLUSION: VE may be a useful method for determining the hardness of CTO lesions noninvasively before endovascular therapy, providing information that can help plan the procedure.

Objective The ratio of hemoglobin to red blood cell distribution width (Hb/RDW) is a simple and readily available tool associated with adverse outcomes in chronic heart failure (HF). However, the association between the Hb/RDW ratio and mortality in patients with acute decompensated HF (ADHF) is unclear. The goal of this study was to investigate the relationship between the Hb/RDW ratio and mortality in patients after ADHF. Methods This single-center study included clinical and laboratory data collected at baseline, with patients prospectively followed-up for a median period of 3.1 years. The patients were divided into two groups based on their median Hb/RDW ratio. Patients We evaluated 250 consecutive patients hospitalized for ADHF at Shinshu University Hospital between July 2014 and March 2019. Results In our study cohort (median age, 76 [66-83] years; 62.8 % male), all-cause death was observed in 91 patients (incidence rate: 12.7 per 100 patient-years). A Kaplan-Meier analysis revealed that patients in the lower Hb/RDW ratio group (<0.24, n=131) had worse outcomes compared to those in the higher group (≥0.24, n=119) (cumulative incidence 44.1% vs. 19.5%, respectively; log-rank, P <0.001). After adjusting for demographics, HF severity, and laboratory biomarkers, a lower Hb/RDW ratio was significantly associated with a higher risk of mortality (hazard ratio, 1.89; 95% confidence interval, 1.04-3.45; P = 0.038). Conclusion A lower Hb/RDW ratio is associated with an increased risk of mortality in patients after ADHF, thus indicating its potential utility in identifying patients at an elevated risk for future cardiovascular events.
RESUMO
BACKGROUND: Lower limb artery disease (LEAD) is accompanied by multiple comorbidities; however, the effect of hyperpolypharmacy on patients with LEAD has not been established. This study investigated the associations between hyperpolypharmacy, medication class, and adverse clinical outcomes in patients with LEAD. METHODS: This study used data from a prospective multicenter observational Japanese registry. A total of 366 patients who underwent endovascular treatment (EVT) for LEAD were enrolled in this study. The primary endpoints were major adverse cardiac events (MACE), including myocardial infarction, stroke, and all-cause death. RESULTS: Of 366 patients with LEAD, 12 with missing medication information were excluded. Of the 354 remaining patients, 166 had hyperpolypharmacy (≥10 medications, 46.9â¯%), 162 had polypharmacy (5-9 medications, 45.8â¯%), and 26 had nonpolypharmacy (<5 medications, 7.3â¯%). Over a 4.7-year median follow-up period, patients in the hyperpolypharmacy group showed worse outcomes than those in the other two groups (log-rank test, pâ¯<â¯0.001). Multivariate analysis revealed that the total number of medications was significantly associated with an increased risk of MACE (hazard ratio per medication increase 1.07, 95â¯% confidence interval 1.02-1.13 pâ¯=â¯0.012). Although an increased number of non-cardiovascular medications was associated with an elevated risk of MACE, the increase in cardiovascular medications was not statistically significant (log-rank test, pâ¯=â¯0.002 and 0.35, respectively). CONCLUSIONS: Hyperpolypharmacy due to non-cardiovascular medications was significantly associated with adverse outcomes in patients with LEAD who underwent EVT, suggesting the importance of medication reviews, including non-cardiovascular medications.
RESUMO
A 29-year-old female patient presented with shock and dyspnea due to heart failure and pulmonary edema. Echocardiography indicated excessive contraction limited to the left ventricular apex and akinesis of the basal and middle ventricle, which were confirmed by emergency left ventriculography. The finding was diagnostic of inverted Takotsubo cardiomyopathy. An abdominal computed tomography scan showed a tumor in the left adrenal gland with a central low-density area, and the plasma and urinary catecholamines were strikingly elevated. Taken together, these findings suggested the presence of a hemorrhagic pheochromocytoma. A myocardial biopsy in the very acute stage on the day of admission revealed neutrophilic infiltration and contraction-band necrosis, which was indistinguishable from the previously reported pathology in the acute phase of idiopathic Takotsubo cardiomyopathy without pheochromocytoma. The diagnosis of pheochromocytoma in this case was confirmed 7 weeks later by surgical removal of the left adrenal gland with massive hemorrhage at the center of the pheochromocytoma. The marked similarity of the endomyocardial pathology between this case and cases with idiopathic Takotsubo cardiomyopathy strongly points to catecholamine excess as a common causality for Takotsubo cardiomyopathy with or without pheochromocytoma.

We assessed the prognostic ability of several inflammation-based scores and compared their long-term outcomes in patients with peripheral artery disease (PAD) following endovascular treatment (EVT). We included 278 patients with PAD who underwent EVT and classified them according to their inflammation-based scores (Glasgow prognostic score [GPS], modified GPS [mGPS], platelet to lymphocyte ratio [PLR], prognostic index [PI], and prognostic nutritional index [PNI]). Major adverse cardiovascular events (MACE) at 5 years were examined, and C-statistics in each measure were calculated to compare their MACE predictive ability. During the follow-up period, 96 patients experienced MACE. Kaplan-Meier analysis showed that higher scores of all measures were associated with a higher MACE incidence. Multivariate Cox proportional hazard analysis showed that GPS 2, mGPS 2, PLR 1, and PNI 1, compared with GPS 0, mGPS 0, PLR 0, and PNI 0, were associated with an increased risk of MACE. C-statistics for MACE for PNI (.683) were greater than those for GPS (.635, P = .021), mGPS (.580, P = .019), PLR (.604, P = .024), and PI (.553, P < .001). PNI is associated with MACE risk and has a better prognosis-predicting ability than other inflammation-scoring models for patients with PAD following EVT.
