RESUMO
OBJECTIVE: Patients with symptomatic lower extremity arterial disease (LEAD) are recommended to receive antiplatelet therapy, while direct oral anticoagulants (DOACs) are standard for stroke prevention in patients with atrial fibrillation (AF). For patients with concomitant LEAD and AF, data comparing dual antithrombotic therapy (an antiplatelet agent used in conjunction with a DOAC) vs. DOAC monotherapy are scarce. This retrospective cohort study, based on data from the Taiwan National Health Insurance Research Database, aimed to compare the efficacy and safety of these antithrombotic strategies. METHODS: Patients with AF who underwent revascularisation for LEAD between 2012 - 2020 and received any DOAC within 30 days of discharge were included. Patients were grouped by antiplatelet agent exposure into the dual antithrombotic therapy and DOAC monotherapy groups. Inverse probability of treatment weighting was used to mitigate selection bias. Major adverse limb events (MALEs), ischaemic stroke or systemic embolism, and bleeding outcomes were compared. Patients were followed until the occurrence of any study outcome, death, or up to two years. RESULTS: A total of 1 470 patients were identified, with 736 in the dual antithrombotic therapy group and 734 in the DOAC monotherapy group. Among them, 1 346 patients received endovascular therapy as the index revascularisation procedure and 124 underwent bypass surgery. At two years, dual antithrombotic therapy was associated with a higher risk of MALEs than DOAC monotherapy (subdistribution hazard ratio [SHR] 1.34, 95% confidence interval [CI] 1.15 - 1.56), primarily driven by increased repeat revascularisation. Dual antithrombotic therapy was also associated with a higher risk of major bleeding (SHR 1.43, 95% CI 1.05 - 1.94) and gastrointestinal bleeding (SHR 2.17, 95% CI 1.42 - 3.33) than DOAC monotherapy. CONCLUSION: In patients with concomitant LEAD and AF who underwent peripheral revascularisation, DOAC monotherapy was associated with a lower risk of MALEs and bleeding events than dual antithrombotic therapy.
RESUMO
The Taiwan Society of Cardiology (TSOC) and Taiwan Society of Plastic Surgery (TSPS) have collaborated to develop a joint consensus for the management of patients with advanced vascular wounds. The taskforce comprises experts including preventive cardiologists, interventionists, and cardiovascular and plastic surgeons. The consensus focuses on addressing the challenges in diagnosing, treating, and managing complex wounds; incorporates the perfusion evaluation and the advanced vascular wound care team; and highlights the importance of cross-disciplinary teamwork. The aim of this joint consensus is to manage patients with advanced vascular wounds and encourage the adoption of these guidelines by healthcare professionals to improve patient care and outcomes. The guidelines encompass a range of topics, including the definition of advanced vascular wounds, increased awareness, team structure, epidemiology, clinical presentation, medical treatment, endovascular intervention, vascular surgery, infection control, advanced wound management, and evaluation of treatment results. It also outlines a detailed protocol for assessing patients with lower leg wounds, provides guidance on consultation and referral processes, and offers recommendations for various wound care devices, dressings, and products. The 2024 TSOC/TSPS consensus for the management of patients with advanced vascular wounds serves as a catalyst for international collaboration, promoting knowledge exchange and facilitating advancements in the field of advanced vascular wound management. By providing a comprehensive and evidence-based approach, this consensus aims to contribute to improved patient care and outcomes globally.
RESUMO
BACKGROUND: The outcomes of patients with concomitant left main coronary artery (LMCA) and right coronary artery (RCA) diseases are reportedly worse than those with only LMCA disease. To date, only few studies have investigated the clinical impact of percutaneous coronary intervention (PCI) on RCA stenosis during the same hospitalization, in which LMCA disease was treated. This study was aimed at comparing the outcomes between patients with and without right coronary artery intervention during the same hospital course for LMCA intervention. METHODS AND RESULTS: From a total of 776 patients who were undergoing PCI to treat LMCA disease, 235 patients with concomitant RCA significant stenosis (more than 70% stenosis) were enrolled. The patients were divided into two groups: 174 patients received concomitant PCI for RCA stenosis during the same hospitalization, in which LMCA disease was treated, and 61 patients did not receive PCI for RCA stenosis. Patients without intervention to the right coronary artery had higher 30-day cardiovascular mortality rates and 3-year RCA revascularization rates compared to those with right coronary artery intervention. Patients without RCA intervention at the same hospitalization did not increase the 30-day total death, 3-year myocardial infarction rate, 3-year cardiovascular death, and 3-year total death. CONCLUSIONS: In patients with LM disease and concomitant above or equal to 70% RCA stenosis, PCI for RCA lesion during the same hospitalization is recommended to reduce the 30-day cardiovascular death and 3-year RCA revascularization rate.

Extracorporeal shock wave (ECSW) and adipose-derived mesenchymal stem cells (ADMSCs) have been recognized to have capacities of anti-inflammation and angiogenesis. We tested the hypothesis that ECSW and ADMSC therapy could attenuate ischemia-reperfusion- (IR-) induced thigh injury (femoral artery tightened for 6 h then the tightness was relieved) in rats. Adult male SD rats (n = 30) were divided into group 1 (sham-control), group 2 (IR), group 3 (IR + ECSW/120 impulses at 0.12 mJ/mm2 given at 3 h/24 h/72 h after IR), group 4 (allogenic ADMSC/1.2 × 106 cell intramuscular and 1.2 × 106 cell intravenous injections 3 h after IR procedure), and group 5 (ECSW + ADMSC). At day 7 after the IR procedure, the left quadriceps muscle was harvested for studies. At 18 h after the IR procedure, serum myoglobin/creatine phosphokinase (CPK) levels were highest in group 2, lowest in group 1, and with intermediate values significantly progressively reduced in groups 3 to 5 (all p < 0.0001). By day 5 after IR, the mechanical paw-withdrawal threshold displayed an opposite pattern of CPK (all p < 0.0001). The protein expressions of inflammatory, oxidative-stress, apoptotic, fibrotic, DNA-damaged, and mitochondrial-damaged biomarkers and cellular expressions of inflammatory and DNA-damaged biomarkers exhibited an identical pattern of CPK among the five groups (all p < 0.0001). The microscopic findings of endothelial-cell biomarkers and number of arterioles expressed an opposite pattern of CPK, and the angiogenesis marker was significantly progressively increased from groups 1 to 5, whereas the histopathology showed that muscle-damaged/fibrosis/collagen-deposition areas exhibited an identical pattern of CPK among the five groups (all p < 0.0001). In conclusion, ECSW-ADMSC therapy is superior to either one applied individually for protecting against IR-induced thigh injury.

BACKGROUND: This study investigated whether body mass index (BMI) was a risk factor predictive of 30-day prognostic outcome in Asians with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). MATERIAL AND METHODS: Data regarding the impact of BMI on the prognostic outcome in Asian populations after acute STEMI is scarce. A number of 925 STEMI patients were divided into three groups according to the BMI: normal weight (<25 kg/m2), overweight (≥25.0 to <30.0 kg/m2) and obese (≥30.0 kg/m2). RESULTS: The obese group was significantly younger with significantly higher incidences of smoking and diabetes mellitus. The incidences of multi-vessel disease, final thrombolysis in myocardial infarction (TIMI)-3 flow, advanced Killip score, advance congestive heart failure, 30-day mortality and combined 30-day major adverse clinical outcome (MACO) did not differ among the three groups. Multiple regression analysis showed the age, unsuccessful reperfusion and lower left ventricular ejection fraction were most significant and independent predictor of 30-day mortality. CONCLUSION: BMI is not a predictor of 30-day prognostic outcome in Asians with STEMI undergoing primary PCI.

BACKGROUND: Both cardiovascular calcification and autonomic dysfunction are frequently encountered in hemodialysis patients. We aimed to investigate the relationship between cardiovascular calcification and heart rate variability (HRV) and their influence on long-term outcome. METHODS: Seventy-eight hemodialysis patients underwent echocardiogram and radiography of the pelvis and hands to identify valvular and vascular calcification. HRV was evaluated using a commercial machine. RESULTS: Based on the average, the patients were divided into higher and lower subgroups of high frequency (HF) and low frequency (LF) respectively. Patients with higher LF were younger and were found to have a lower proportion of diabetes. Their hemoglobin, albumin, and bone morphogenic protein (BMP)-7 levels were significantly higher and both high-sensitive C-reactive protein (hs-CRP) and osteoprotegerin levels were lower (all p < 0.05). In patients of the higher HF group, the proportion of diabetes was lower but they were found to have higher levels of BMP-7 and lower levels of hs-CRP, interleukin-6 (all p < 0.05). Significantly higher LF and HF were noted in patients without vascular calcification, but only hand artery (HA) calcification was negatively correlated with both LF and HF in multivariate analysis. Low LF and high hs-CRP were the independent predictors of mortality. Coexistence of low LF band and HA calcification was associated with the worse outcome. CONCLUSIONS: Abnormal autonomic nervous function was closely related to inflammation and mortality in hemodialysis patients. Calcification of HA was associated with autonomic dysfunction and patients with lower autonomic tone and HA calcification had the highest mortality rate in this population.

To investigate the postprocedural cardiovascular events and vascular outcomes, including hand ischemia and neurological compromise, after transulnar (TU) catheterization in ipsilateral radial artery occlusion.Previous randomized trials have shown that the transulnar (TU) approach for coronary angiogram and intervention has safety and outcomes similar to those of the transradial (TR) approach. However, the safety of the TU procedure when ipsilateral radial artery occlusion occurs is unknown.We retrospectively reviewed 87 TU cases with ipsilateral radial artery occlusion confirmed by a forearm angiogram. Eighty percent of these patients had a history of ipsilateral radial artery cannulation or surgery. We avoided the use of over-sized sheaths or applied a sheathless approach during surgery.No ulnar artery occlusion was observed by subsequent Doppler ultrasound or pulse oximetry. No patient developed hand ischemia or serious complications requiring surgery or blood transfusion during the follow-up period of 32.2 ± 24.0 months. Review of the preprocedural forearm angiograms showed that 95.7% of the patients possessed significant collaterals supplying flow from the interosseous artery to the occluded radial artery remnant. Thus, the blood circulation to the palmar arch and digital vessels was maintained even when the ulnar artery was temporarily occluded by an in-dwelling ulnar arterial sheath.TU catheterization was safe in patients with coexisting ipsilateral radial artery occlusions and feasible for use in complex intervention procedures. Cautious manipulation of ulnar artery cannulation and hemostasis helped decrease the risk of hand ischemia.

Several risk stratification scores, based on angiographic or clinical parameters, have been developed to evaluate outcomes in patients with left main coronary artery disease (LMCAD) who undergo coronary artery bypass grafting (CABG). This study aims to validate the predictive ability of different risk scoring systems with regard to long-term outcomes after CABG. This single-center study retrospectively re-evaluated the Synergy Between PCI with TAXUS and Cardiac Surgery (SYNTAX) score; EuroSCORE; age, creatinine, and ejection fraction (ACEF) score; modified ACEF score; clinical SYNTAX; logistic clinical SYNTAX score (logistic CSS); and Parsonnet scores for 305 patients with LMCAD who underwent CABG. The endpoints were 5-year rate of all-cause death and major adverse cardio-cerebral events (MACCEs), including cardiovascular (CV) death, myocardial infarction (MI), and stroke and target vessel revascularization (TVR). Compared with the SYNTAX score, other scores were significantly higher in discriminative ability for all-cause death (SYNTAX vs others: Pâ<â0.01). The EuroSCORE ≥6 showed significant outcome difference on all-cause death, CV death, MI, and MACCE (Pâ<â.01). Multivariate analysis indicated the SYNTAX score was a non-significant predictor for different outcomes. Adjusted multivariate analysis revealed that the EuroSCORE was the strongest predictor of all-cause death (hazard ratio[HR]: 1.17; Pâ<â0.001), CV death (HR: 1.16; Pâ<â0.001), and MACCE (HR: 1.09; Pâ=â0.01). The ACEF score and logistic CSS were predictive factors for TVR (HR: 0.25, Pâ=â0.03; HR: 0.85, Pâ=â0.01). The EuroSCORE scoring system most accurately predicts all-cause death, CV death, and MACCE over 5 years, whereas low ACEF score and logistic CSS are independently associated with TVR over the 5-year period following CABG in patients with LMCAD undergoing CABG.

AIMS: Contrast-induced nephropathy (CIN) is a leading cause of morbidity and mortality in patients undergoing percutaneous coronary intervention (PCI). Limited data, however, are available on predictors of CIN in PCI for chronic total occlusion (CTO) lesions. The aim of the study was to determine the risk of developing CIN in patients undergoing CTO PCI by studying the effects of clinical variables, interventional techniques, and CTO lesion characteristics on renal function. METHODS AND RESULTS: This retrospective analysis included consecutive patients referred for CTO PCI between January 2002 and December 2009. CIN was defined as an elevated serum creatinine level ≥25% of baseline serum creatinine level at 48-72 hours after procedure. Patient characteristics, Mehran score, lesion characteristics, interventional procedure, and devices used were compared between CIN and non-CIN groups. For the 516 patients eligible for analysis, the incidence of CIN was 5.4% (28/516). Two patients needed transient haemodialysis (0.4%, 2/516). Analysis of risk using Mehran scoring found that the incidence of CIN was 0.5% (1/207) among low-risk patients, 3.4% (7/205) among moderate-risk patients, 15.9% (14/88) among high-risk patients and 37.5% (6/16) among very high-risk patients. The Mehran score high-risk group (11-15) and the very high-risk group (≥16) were definitely predictors of CIN after CTO PCI (OR: 27.022 [95% CI: 2.787-262.028, p=0.004]; OR: 32.512 [95% CI: 2.149-491.978, p=0.012]). Severe tortuosity was the only predictor of CIN after CTO PCI in angiographic and procedural findings (OR: 6.621 [95% CI: 1.090-40.227, p=0.040]). CONCLUSIONS: Being in the Mehran score high-risk group (11-15) or the very high-risk group (≥16) and severe tortuosity were predictors of CIN after CTO PCI.

The efficacy of percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) has improved dramatically due to the development of new devices. Severe calcification of coronary lesions may be encountered even when the guidewire crosses the CTO, preventing the balloon from penetrating the lesion. A new "Tornus" penetration catheter has been developed for CTO recanalization. The purpose of this study was to evaluate the feasibility and safety of the Tornus catheter compared with traditional rotational atherectomy for CTO lesions. From August 2002 to July 2009, 77 patients with CTO of the coronary artery were selected to undergo PCI. Forty-one patients were treated with rotational atherectomy before the availability of the Tornus catheter when the smallest balloon failed to pass the CTO lesion. Later, 36 patients were treated with a Tornus catheter. Device and angiographic success rates as well as procedural complications were assessed. Device success was defined when the Tornus or Rota burr passed through the lesion. Major complications included death, Q-myocardial infarction, or emergency bypass surgery. Minor complications included perforation, cardiac tamponade, no reflow phenomenon, or long spiral dissection.The mean procedural time was significantly longer in the Tornus group (144 minutes versus 115 minutes, P = 0.01), while the device success rate was significantly lower (77% versus 95%, P = 0.024). Rotational atherectomy was subsequently performed in 3 of 8 Tornus failure cases. There were no between group differences in major complication rate (6% Tornus versus 5% rotational atherectomy). There was an insignificant trend for lower minor complication rates in the Tornus group (17% versus 20%).Use of the Tornus catheter was associated with significantly longer procedural duration and lower device success rates compared to rotational atherectomy. Major and minor complications were not different between the groups. Our findings suggest that Tornus catheter penetration is not superior to conventional rotational atherectomy for CTO recanalization.

BACKGROUND: Although recent studies suggest that percutaneous coronary intervention (PCI) with drug-eluting stents (DES) achieves clinical outcomes comparable to coronary artery bypass graft surgery (CABG) for unprotected left main coronary artery (ULMCA) disease, long-term studies are rarely performed. METHODS AND RESULTS: This study reviewed outcomes in 363 patients undergoing CABG (n=216), PCI with DES (n=94) or PCI with bare-metal stent (BMS) (n=53) for ULMCA stenosis between January 2000 and March 2007. The CABG group had more patients with diabetes (50.5%) and 3- or 4-vessel disease (77.3%) than the PCI group. Kaplan-Meier survival estimates showed higher TLR-free survival and revascularization-free survival in CABG group. Although cardiac-death-free survival did not significantly differ between the 3 groups, the DES group had the highest overall survival. Age (hazard ratio (HR): 1.060; 95% confidence interval (CI): 1.017-1.104) and diffuseness score (HR: 1.157; 95%CI: 1.019-1.313) were significant independent risk factors for cardiac death. CONCLUSIONS: There was higher TLR in the PCI group with either DES or BMS, but cardiac death did not significantly differ between the 3 groups. Advanced age and diffuse coronary atherosclerosis may increase the risk of cardiac death following revascularization.

BACKGROUND: Acute ST-segment elevation myocardial infarction (STEMI) caused by left main coronary artery (LMCA) obstruction is uncommon. Although the link between this catastrophic disease and very high mortality is well recognized, even after undergoing emergent revascularization, the systemic risk stratification and long-term outcome are currently unclear. The clinical presentation, parameter-related in-hospital death and long-term outcomes of these patients with acute LMCA obstruction undergoing emergency revascularization were carefully reviewed. METHODS AND RESULTS: From January 2000 through December 2007, 1,588 patients were diagnosed to have STEMI and received emergent cardiac catheterization. The 38 (2.4%) of these 1,588 patients were enrolled into the present study due to LMCA obstruction. The analytical results identified the 30-day mortality rate as 42.1% (16/38). Multivariate analysis demonstrated that renal insufficiency was independently predictive of in-hospital mortality (odds ratio (OR): 5.642; p = 0.029), whereas successful revascularization was independently predictive of freedom from in-hospital mortality (OR: 0.174; p = 0.044). The cut-off value of a Parsonnet score > 20 was strongly associated with 30-day mortality (p = 0.002). CONCLUSIONS: Even undergoing emergency revascularization for patients with acute LMCA obstruction, the in-hospital mortality remains very high. Additionally, the worse clinical outcome was observed in those with renal insufficiency and Parsonnet score of > 20.

BACKGROUND: Percutaneous coronary intervention (PCI) is considered an excellent alternative treatment for unprotected left main coronary artery (ULMCA) stenoses. Most PCIs for ULMCA stenoses are performed via the transfemoral approach. The feasibility and safety of the transradial approach for this particular entity are unknown. The present study assessed the feasibility, safety and 1-year outcomes of the transradial approach for stenting of ULMCA stenoses. METHODS AND RESULTS: Of 131 consecutive patients who underwent coronary stenting for ULMCA stenoses, 113 patients (86.3%) received stenting using the transradial approach. All 113 procedures were performed with 6 or 7 French (Fr) catheters except 1 procedure requiring an 8 Fr guiding catheter for directional atherectomy. The technical success rate was 100%, and angiographic success was achieved in 96 patients (85.9%). Two patients had local hematoma (1.8%), and no procedure-related deaths, Q-wave myocardial infarction, repetitive PCI, stroke or emergent coronary artery bypass graft surgery during hospitalization were noted. One (0.9%) in-hospital cardiac death occurred due to ventricular tachyarrhythmia. More than half of our patients stayed in hospital by < or =3 days. The 1-year target lesion revascularization and cardiac death rate were 14.2% and 3.5%, respectively. CONCLUSIONS: This investigation demonstrated the feasibility, safety and accepted short-term clinical outcomes of transradial stenting for ULMCA stenosis. This procedure may offer a feasible alternative to the transfemoral approach.
