[Preventive myocardial revascularization prior to abdominal aortic repair in patients without cardiac symptoms: long-term results]. / Profilakticheskaya revaskulyarizatsiya miokarda pered rezektsiei anevrizmy bryushnoi aorty u kardiologicheski asimptomnykh bol'nykh: otdalennye rezul'taty.

OBJECTIVE: To evaluate the long-term influence of preoperative invasive coronary screening and preventive myocardial revascularization on mortality and cardiac complications after open surgery for abdominal aortic aneurysms (AAA). MATERIAL AND METHODS: We present long-term outcomes after open surgery for AAA between 2011 and 2022. Patients without clinical or objective signs of coronary artery disease were included. In the 1st group, routine coronary angiography was performed before surgery. Prophylactic myocardial revascularization was performed in 12 cases. Long-term data on 45 patients were obtained. In the 2nd group, 53 patients underwent repair without invasive coronary screening, and data on 48 patients were obtained in this group. RESULTS: The median follow-up was 32 and 79 months, respectively. Kaplan-Meyer overall 48-month survival was 87.3% and 82.1%, respectively (p=0.278). In the first group, 2 patients developed angina pectoris in the same period. In the second group, we observed 2 cases of myocardial infarction and 3 cases of angina pectoris without infarction. Analysis of survival curves found no significant differences (p=0.165). CONCLUSION: In our study, invasive coronary screening and preventive myocardial revascularization in patients without clinical and objective signs of coronary artery did not improve 4-year long-term period after abdominal aortic repair. Perhaps, differences will appear after 4 years, and this requires further follow-up after coronary angiography. However, there is a tendency towards more common onsets of coronary artery disease that dictates the need for cardiac monitoring of such patients.

[Fifteen-year results of bilateral and unilateral internal mammary artery grafting]. / Pyatnadtsatiletnie rezul'taty revaskulyarizatsii miokarda s ispol'zovaniem dvukh i odnoi vnutrennei grudnoi arterii.

OBJECTIVE: To evaluate the clinical effectiveness of bilateral internal mammary artery grafting over long-term (15 years) postoperative period. MATERIAL AND METHODS: There were 276 patients divided into two groups: 135 patients (group A) underwent bilateral internal mammary artery grafting and 141 patients (group B) underwent unilateral internal mammary artery grafting together with venous bypass grafts. On-pump surgeries and cardioplegia, parallel CPB and on-pump procedures were performed in equal proportions. Mean age of patients was 57.3±7.6 years. Diabetes mellitus was detected in 21 (15.5%) and 24 (19.1%) patients, respectively (p>0.05). Mean LV ejection fraction was 55.4±9.9%, revascularization index - 3.1±0.8 and 3.0±0.7, respectively. In the 1st group, 43 patients underwent bilateral internal mammary artery grafting alone. Autovenous grafts were additionally used in other 84 patients. RESULTS: Ten-year survival exceeded 90% in both groups. Freedom from adverse cardiac events after 15 years was significantly higher in group A (77.3% vs. 59.3%, p=0.018). In group A, 16 patients died throughout this period due to cancer (50%), myocardial infarction (12.5%), stroke (18.8%) and complications of diabetes mellitus (6.3%). In group B, 22 patients died mainly from cardiac causes (myocardial infarction - 40.9%, cancer - 27.3%). CONCLUSION: Bilateral internal mammary artery grafting has obvious advantages over traditional coronary artery bypass grafting. If we take into account higher proportion of cardiac causes in structure of mortality in group B, we can talk about positive impact of bilateral internal mammary artery grafting not only on the quality of life, but also on life expectancy in long-term postoperative period.

Association between type 2 diabetes and long-term outcomes in middle-aged and older trauma patients.

BACKGROUND: Diabetes is associated with increased hospital complications and mortality following trauma. However, there is limited research on the longer-term recovery of trauma patients with diabetes. The aim of this study was to explore the association between type 2 diabetes (T2D) and in-hospital and 24-month outcomes in major trauma patients. METHODS: In this cohort study using the Victorian State Trauma Registry, middle-aged and older adults (≥45 years) with major trauma were followed up at 24 months postinjury. Logistic regression (univariable and multivariable) analyses were used to determine the association between diabetes status and 24-month patient-reported outcomes. In-hospital outcomes were compared between groups using χ2 tests. RESULTS: Of the 11,490 participants who survived to hospital discharge, 8,493 survived to 24 months postinjury and were followed up at that time point: 953 people (11%) with and 7540 (89%) without T2D. People with T2D had a higher in-hospital death rate (19%) compared with people without T2D (16%; p < 0.001). After adjusting for confounders, people with T2D had poorer outcomes 24 months postinjury than people without T2D, with respect to functional recovery (Glasgow Outcome Scale Extended) (adjusted odds ratio [AOR], 0.58; 95% confidence interval [CI], 0.48-0.69) and return to work/study (AOR, 0.51; 95% CI, 0.37-0.71]). People with T2D experienced higher odds of problems with mobility (AOR, 1.92; 95% CI, 1.60-2.30), self-care (AOR, 1.94; 95% CI, 1.64, 2.29), usual activities (AOR, 1.50; 95% CI, 1.26-1.79), pain and discomfort (AOR, 1.75; 95% CI, 1.49-2.07), anxiety and depression (AOR, 1.45; 95% CI, 1.24, 1.70), and self-reported disability (AOR, 1.51; 95% CI, 1.28-1.79) than people without T2D. CONCLUSION: Major trauma patients with T2D have a poorer prognosis than patients without T2D, both during their hospital admission and 24 months postinjury. Patients with T2D may need additional health care and support following trauma to reach their recovery potential. LEVEL OF EVIDENCE: Prognostic, level III.

Cardiac allograft rejection in the current era of continuous flow left ventricular assist devices.

OBJECTIVE: Left ventricular assist device (LVAD) implantation has been shown to increase allosensitization before orthotopic heart transplantation, but the influence of LVAD support on posttransplant rejection is controversial. This study examines the postoperative incidence of acute cellular rejection (ACR) in patients bridged with continuous flow LVAD (CF-LVAD) relative to primary transplant (Primary Tx). METHODS: All patients who underwent orthotopic heart transplantation at our institution between July 2006 and March 2019 were retrospectively reviewed (n = 395). Patients were classified into Primary Tx (n = 145) and CF-LVAD (n = 207) groups. Propensity score matching on 13 covariates implemented a 0.1 caliper logistic model with nearest neighbor 1:1 matching. Development of moderate to severe (ie, 2R/3R) rejection was evaluated using a competing risks model. Potential predictors of 2R/3R ACR were evaluated using Fine-Gray regression on the marginal subdistribution hazard. RESULTS: Propensity score matching yielded 122 patients in each group (n = 244). At 12 and 24 months, the cumulative incidence of 2R/3R ACR was 17% and 23% for the CF-LVAD group and 26% and 31%, respectively, for the Primary Tx group (P = .170). CF-LVAD was not predictive of 2R/3R rejection on multivariable Fine-Gray regression (subdistribution hazard ratio, 0.73; 95% confidence interval, 0.40-1.33; P = .301). There was no difference in the 5-year incidence of antibody mediated rejection (10% [n = 12] vs 9% [n = 11]; P = .827). CONCLUSIONS: After adjusting for covariates, CF-LVAD was not associated with an increased risk of moderate to severe ACR during the 24 months after cardiac transplantation. Further investigation is warranted with larger cohorts, but CF-LVAD may have minimal influence on posttransplant ACR.

Aortic root replacement with bicuspid valve reimplantation: Are outcomes and valve durability comparable to those of tricuspid valve reimplantation?

OBJECTIVES: To assess intermediate-term outcomes of aortic root replacement with valve-sparing reimplantation of bicuspid aortic valves (BAV), compared with tricuspid aortic valves (TAV). METHODS: From January 2002 to July 2017, 92 adults underwent aortic root replacement with BAV reimplantation and 515 with TAV reimplantation at the Cleveland Clinic. Balancing-score matching based on 28 preoperative variables yielded 71 well-matched BAV and TAV pairs (77% of possible pairs) for comparison of postoperative mortality and morbidity, longitudinal echocardiogram data, aortic valve reoperation, and survival. RESULTS: In the BAV group, 1 hospital death occurred (1.1%); mortality among all reimplantations was 0.2%. Among matched patients, procedural morbidity was low and similar between BAV and TAV groups (1 stroke in TAV group; renal failure requiring dialysis, 1 patient each; red cell transfusion, 25% each). Five-year results: Severe aortic regurgitation was present in 7.4% of the BAV group and 2.9% of the TAV group (P = .7); 39% of BAV and 65% of TAV patients had none. Higher mean gradients (10 vs 7.4 mm Hg; P = .001) and left ventricular mass index (111 vs 101 g/m2; P = .5) were present in BAV patients. Freedom from aortic valve reoperation was 94% in the BAV group and 98% in the TAV group (P = .10), and survival was 100% and 95%, respectively (P = .07). CONCLUSIONS: Both BAV and TAV reimplantations can be performed with equal safety and good midterm outcomes; however, the constellation of higher gradients, less ventricular reverse remodeling, and more aortic valve reoperations with BAV reimplantations raises concerns requiring continued long-term surveillance.

Low left ventricular ejection fraction, complication rescue, and long-term survival after coronary artery bypass grafting.

OBJECTIVES: To evaluate the association between low left ventricular ejection fraction (LVEF), complication rescue, and long-term survival after isolated coronary artery bypass grafting. METHODS: National cohort study of patients who underwent isolated coronary artery bypass grafting (2000-2016) using Veterans Affairs Surgical Quality Improvement Program data. Left ventricular ejection fraction was categorized as ≥35% (n = 55,877), 25%-34% (n = 3893), or <25% (n = 1707). Patients were also categorized as having had no complications, 1 complication, or more than 1 complication. The association between LVEF, complication rescue, and risk of death was evaluated with multivariable Cox regression. RESULTS: Among 61,477 patients, 6586 (10.7%) had a perioperative complication and 2056 (3.3%) had multiple complications. Relative to LVEF ≥35%, decreasing ejection fraction was associated with greater odds of complications (25%-34%, odds ratio, 1.30 [1.18-1.42]; <25%, odds ratio, 1.65 [1.43-1.92]). There was a dose-response relationship between decreasing LVEF and overall risk of death (≥35% [ref]; 25%-35%, hazard ratio, 1.46 [1.37-1.55]; <25%, hazard ratio, 1.68 [1.58-1.79]). Among patients who were rescued from complications, there were decreases in 10-year survival, regardless of LVEF. Among those rescued after multiple complications, LVEF was no longer associated with risk of death. CONCLUSIONS: While decreasing LVEF is associated with post-coronary artery bypass grafting complications, patients rescued from complications have worse long-term survival, regardless of left ventricular function. Prevention and timely treatment of complications should remain a focus of quality improvement initiatives, and future work is needed to mitigate their long-term detrimental impact on survival.

Endoscopic Management of Low-Grade Upper Tract Urothelial Carcinoma: Characterizing the Long-term Burden of Care in Comparison to Radical Nephroureterectomy.

OBJECTIVE: To compare procedure burden, oncologic, surgical and renal-function outcomes between patients with low-grade upper urothelial cancer (UTUC) who were referred for either radical management (RM) or kidney-sparing endoscopic management (EM). PATIENTS AND METHODS: We retrospectively reviewed data of all patients treated for UTUC at our tertiary medical center between 2000 and 2018 and selected patients diagnosed with unilateral low-grade UTUC. RESULTS: Twenty-four patients were treated with EM and 37 with RM. Surgical and oncologic risk factors were similar between the arms except for tumor size. Mean follow-up was 4.9 ± 3.4 years. The 5-year overall-survival rate was 85% with EM and 84% with RM (P = .707). Metastasis-free and cancer-specific survival were also similar (P = .994, P = .960). End-of-follow-up average glomerular filtration rates were 58.7 ± 21.5 and 49.2 ± 22.1 mL/min/1.73 m2, respectively (P = .12). Ninety-two percent of patients managed endoscopically had local recurrences, with an average of 3.2 recurrences per patient. Four (17%) patients underwent salvage radical nephroureterectomy. Procedure burden was higher with EM, having 6.5 ± 4.4 operations and 344 ± 272 minutes under anesthesia compared with 1.9 ± 0.4 operations (P <.0001) and 213 ± 84 minutes under anesthesia (P = .031) with RM. Cost-of-care analysis revealed higher costs for EM in both private and publicly funded medical insurance plans. CONCLUSION: Patients undergoing endoscopic management had an 83% chance of preserving their kidney and an 81% chance of 5-year metastasis-free survival at a cost of 6.5 ± 4.4 operations during a mean follow-up of 4.9 ± 3.4 years. Our findings support EM for low-grade UTUC as a valid option from oncological aspects but highlight the associated costs.

Long-term outcomes of Holmium laser enucleation of prostate and predictive model for symptom recurrence.

INTRODUCTION AND OBJECTIVES: Holmium laser enucleation of prostate (HoLEP) represents one of the most studied surgical techniques for benign prostatic hyperplasia (BPH). Its efficacy in symptom relief has been widely depicted. However, few evidence is available regarding the possible predictors of symptom recurrence. We aimed to evaluate long-term outcomes, symptom recurrence rate, and predictors in patients that underwent HoLEP. MATERIALS AND METHODS: We retrospectively analyzed data from patients that consecutively underwent HoLEP for BPH from 2012 to 2015 at two tertiary referral centers. Functional outcomes were evaluated by uroflowmetry parameters and International Prostate Symptom Score (IPSS) questionnaire administration at follow-up visits at 12, 24, and 60 months. The primary outcome was the symptomatic patients' rate presenting lower urinary tract symptoms (LUTS) after 60 months from surgery, defined as in case of one or more of the following: IPSS more than 7, post voidal residue (PVR) more than 20 ml, need for medical therapy for LUTS or redo surgery for bladder outlet obstruction. Multivariable logistic regression analyses evaluated predictors for being symptomatic at follow-up. Covariates consisted of: preoperative peak flow rate (PFR), PVR, and IPSS, prostate volume, age (all as continuous), and surgical technique. RESULTS: A total of 567 patients were available for our analyses. Median prostate volume was 80cc, with a median PFR of 8 ml/s and median PVR of 100cc. One hundred and twenty-five (22%) patients were found to be symptomatic at follow-up. Redo surgery was needed for 25 (4.4%) patients. After adjusting for possible confounders, an increase in preoperative PVR (odds ratio [OR] 1.005) and IPSS (OR 1.12) resulted as independent predictors for symptom recurrence (all p < 0.001). CONCLUSIONS: HoLEP can provide durable symptom relief regardless of the chosen technique. Patients with an important preoperative symptom burden or a high PVR should be carefully counseled on the risk of symptom recurrence.

Long-term outcomes of the arterial switch operation.

OBJECTIVES: The arterial switch operation (ASO) has excellent early outcomes in the modern era. We sought to determine the long-term outcomes in patients who underwent an ASO at a single institution. METHODS: Patients who underwent an ASO between 1983 and 2015 were identified from the hospital database and retrospectively reviewed using hospital records. RESULTS: From 1983 to 2015, 844 patients with a biventricular circulation underwent an ASO. There were 28 (3.3%, 28/844) early deaths. Follow-up was available for 94% (729/774) of local patients after hospital discharge. Median follow-up was 15 years (interquartile range, 8-20 years). There were 187 (26%, 187/729) patients with more than 20 years of follow-up and 95 (13%, 95/729) patients with more than 25 years of follow-up. Overall survival was 95% (95% confidence interval [CI], 94%-97%) at 10 and 25 years after the ASO. At 25 years after ASO, freedom from overall reintervention was 77% (95% CI, 73%-81%), freedom from reoperation on the neoaortic root or neoaortic valve was 92% (95% CI, 88%-95%), and freedom from coronary reoperation was 99% (95% CI, 98%-99.7%). Left ventricular (LV) systolic function was normal in 595 of 609 (98%) of patients who had LV function quantified at latest follow-up. Of the 95 patients with more than 25 years of follow-up after ASO, 6 (6.3%) had at least moderate neoaortic valve regurgitation (AR) and 8 (8.4%) had undergone replacement of the neoaortic valve. CONCLUSIONS: Overall, survivors of ASO have excellent late survival and normal LV systolic function into adult life. However, AR and reoperation on the neoaortic valve remains an issue for older patients.

Long-term outcomes of truncus arteriosus repair: A modulated renewal competing risks analysis.

OBJECTIVE: In this study, we sought to identify independent risk factors for mortality and reintervention after early surgical correction of truncus arteriosus using a novel statistical method. METHODS: Patients undergoing neonatal/infant truncus arteriosus repair between January 1984 and December 2018 were reviewed retrospectively. An innovative statistical strategy was applied integrating competing risks analysis with modulated renewal for time-to-event modeling. RESULTS: A total of 204 patients were included in the study. Mortality occurred in 32 patients (15%). Smaller right ventricle to pulmonary artery conduit size and truncal valve insufficiency at birth were significantly associated with overall mortality (right ventricle to pulmonary artery conduit size: hazard ratio, 1.34; 95% confidence interval, 1.08-1.66, P = .008; truncal valve insufficiency: hazard ratio, 2.5; 95% confidence interval, 1.13-5.53, P = .024). truncal valve insufficiency at birth, truncal valve intervention at index repair, and number of cusps (4 vs 3) were associated with truncal valve reoperations (truncal valve insufficiency: hazard ratio, 2.38; 95%, confidence interval, 1.13-5.01, P = .02; cusp number: hazard ratio, 6.62; 95% confidence interval, 2.54-17.3, P < .001). Right ventricle to pulmonary artery conduit size 11 mm or less was associated with a higher risk of early catheter-based reintervention (hazard ratio, 1.54; 95% confidence interval, 1.04-2.28, P = .03) and reoperation (hazard ratio, 1.96; 95% confidence interval, 1.33-2.89, P = .001) on the right ventricle to pulmonary artery conduit. CONCLUSIONS: Smaller right ventricle to pulmonary artery conduit size and truncal valve insufficiency at birth were associated with overall mortality after truncus arteriosus repair. Quadricuspid truncal valve, the presence of truncal valve insufficiency at the time of diagnosis, and truncal valve intervention at index repair were associated with an increased risk of reoperation. The size of the right ventricle to pulmonary artery conduit at index surgery is the single most important factor for early reoperation and catheter-based reintervention on the conduit.

Capsule Endoscopy Is Useful for Postoperative Tight Control Management in Patients with Crohn's Disease.

BACKGROUND: In Crohn's disease, postoperative endoscopic activity of small bowel lesions outside the scope of ileocolonoscopy has been insufficiently studied. AIMS: We aimed to assess this postoperative activity using capsule endoscopy (CE) and analyze the association between treatment optimization based on CE findings and the long-term course. METHODS: In patients who underwent intestinal resection, we performed CE and assessed the endoscopic activity using the Lewis score within 3 months postoperatively (1st CE) and during follow-up. Postoperative treatments were adjusted according to clinical symptoms or CE findings (severity of 1st CE or worsening of follow-up CEs). Hospitalization, repeat surgery, or endoscopic dilation defined the primary outcome. RESULTS: Among the CE group (N = 48), 85.7% (1st CE) and 79.2% (2nd CE) exhibited endoscopic activities indicating residual or recurrent lesions. Postoperative treatments were adjusted according to clinical symptoms in the non-CE group (N = 57) and clinical symptoms or CE findings in the CE group. Compared to the non-CE group, the CE group had significantly fewer primary outcomes. Patients with treatment adjustments based on CE findings had even lower primary outcome rate. Multivariate analysis identified the CE group as an independent protective factor (hazard ratio = 0.45, 95% confidence interval = 0.20-0.96). Treatment adjustments based on CE findings showed a stronger protective effect (0.30, 0.10-0.75). CONCLUSIONS: Postoperative repeated CE enabled us to assess residual and recurrent lesions accurately before clinical symptoms appeared. The regular assessment of endoscopic activity and subsequent treatment optimization have the potential for improving postoperative course.

Breast Implants: Common Questions and Answers.

Breast implants are used for a wide range of cosmetic and reconstructive purposes. In addition to breast augmentation, implants can be used for postmastectomy breast reconstruction, correction of congenital breast anomalies, breast or chest wall deformities, and male-to-female top surgery. Breast implants may confer significant benefits to patients, but several factors are important to consider preoperatively, including the impact on mammography, future lactation, and potential long-term implant complications (e.g., infection, capsular contracture, rupture, and the need for revision, replacement, or removal). A fundamental understanding of implant monitoring is also paramount to implant use. Patients with silicone breast implants should undergo routine screening for implant rupture with magnetic resonance imaging or ultrasonography completed five to six years postoperatively and then every two to three years thereafter. With the exception of complications, there are no formal recommendations regarding the timing of breast implant removal or exchange. Women with unilateral breast swelling should be evaluated with ultrasonography for an effusion that might indicate breast implant-associated anaplastic large cell lymphoma. There are no specific breast cancer screening recommendations for patients with breast implants, but special mammographic views are indicated to enhance accuracy. Although these discussions are a routine component of consultation and postoperative follow-up for plastic surgeons performing these procedures, family physicians should have a working knowledge of implant indications, characteristics, and complications to better counsel their patients, to ensure appropriate screening, and to coordinate care after surgery.

Surveillance Imaging Following Acute Type A Aortic Dissection.

BACKGROUND: Survivors of acute type A aortic dissection (ATAAD) repair remain at risk for long-term complications. Guidelines recommend postoperative imaging surveillance, but adherence is uncertain. OBJECTIVES: The aim of this study was to define the real-world frequency of postoperative imaging and characterize long-term outcomes of ATAAD. METHODS: Population-based administrative health databases for Ontario, Canada, were linked to identify patients who underwent ATAAD repair and survived at least 90 days. Guideline-directed imaging surveillance (GDIS) was defined as undergoing a computed tomographic or magnetic resonance imaging scan at 6 and 12 months postoperatively and then annually thereafter. Multivariable time-to-event analysis explored the associations between GDIS and all-cause mortality and reintervention. RESULTS: A total of 888 patients who survived urgent ATAAD repair between April 1, 2005, and March 31, 2018, were included. Median follow-up after ATAAD repair was 5.2 years (interquartile range: 2.4-7.9 years). A total of 14% patients received GDIS throughout follow-up. At 6 years, 3.9% of patients had received GDIS. The mortality rate was 4% at 1 year, 14% at 5 years, and 29% at 10 years. Incidence of aortic reintervention was 3% at 1 year, 9% at 5 years, and 17% at 10 years; the majority of these were urgent (68%), and they carried a 9% 30-day mortality rate. Greater adherence to GDIS was associated with mortality (hazard ratio: 1.08; 95% confidence interval: 1.05-1.11) and reintervention (hazard ratio: 1.04; 95% confidence interval: 1.01-1.07). CONCLUSIONS: Adherence to GDIS following ATAAD repair is poor, while long-term mortality and reinterventions remain substantial. Further research is needed to determine if guidelines should be modified.

Long-term pulmonary function, thoracic pain, and quality of life in patients with one or more rib fractures.

BACKGROUND: Long-term outcomes after rib fractures and the effect of treatment modality or chest wall injury severity on these outcomes remains uncertain. This retrospective cohort study evaluated the long-term pulmonary function, thoracic pain, and quality of life in patients admitted with rib fractures. METHODS: Patients admitted with rib fractures between January 1, 2012, and December 1, 2019, were included. Data on long-term outcomes were collected during one follow-up visit. Patients were stratified by chest wall injury severity (one or two rib fractures, ≥3 rib fractures, or a flail chest) and treatment modality (surgical stabilization of rib fractures [SSRF] or nonoperative management). Multivariable analysis was performed to compare outcomes after SSRF with nonoperative treatment in patients with three or more rib fractures. RESULTS: In total, 300 patients were included. The median follow-up was 39 months (P25-P75, 18-65 months). At follow-up, the corrected forced vital capacity returned to 84.7% (P25-P75, 74.3-93.7) and the forced expiratory volume in 1 second to 86.3% (P25-P75, 75.3-97.0) of the predicted reference values. Quality of life was determined using the Short Form-12 version 2 and EuroQoL-5D-5L. The Short Form-12 version 2 physical and mental component summary were 45 (P25-P75, 38-54) and 53 (P25-P75, 43-60), respectively. The EuroQoL-5D-5L utility score was 0.82 (P25-P75 0.66-0.92) and visual analog scale score 75 (P25-P75 70-85). This indicated a quality of life within normal population ranges. Moderate to severe thoracic pain was reported by 64 (21.3%) patients. Long-term outcomes returned to values within population ranges and were similar across chest wall injury severity and for patients treated with SSRF or nonoperatively. CONCLUSION: While long-term pulmonary function and quality of life recover to values considered normal, subjective thoracic complaints, such as pain and dyspnea, remain frequently present following rib fractures. No effect of chest wall injury severity or treatment modality on long-term outcomes was demonstrated. LEVEL OF EVIDENCE: Therapeutic, level III.

Effect of Heart Failure on Long-Term Clinical Outcomes After Percutaneous Coronary Intervention Versus Coronary Artery Bypass Grafting in Patients With Severe Coronary Artery Disease.

Background Heart failure might be an important determinant in choosing coronary revascularization modalities. There was no previous study evaluating the effect of heart failure on long-term clinical outcomes after percutaneous coronary intervention (PCI) relative to coronary artery bypass grafting (CABG). Methods and Results Among 14 867 consecutive patients undergoing first coronary revascularization with PCI or isolated CABG between January 2011 and December 2013 in the CREDO-Kyoto PCI/CABG registry Cohort-3, we identified the current study population of 3380 patients with three-vessel or left main coronary artery disease, and compared clinical outcomes between PCI and CABG stratified by the subgroup based on the status of heart failure. There were 827 patients with heart failure (PCI: N=511, and CABG: N=316), and 2553 patients without heart failure (PCI: N=1619, and CABG: N=934). In patients with heart failure, the PCI group compared with the CABG group more often had advanced age, severe frailty, acute and severe heart failure, and elevated inflammatory markers. During a median 5.9 years of follow-up, there was a significant interaction between heart failure and the mortality risk of PCI relative to CABG (interaction P=0.009), with excess mortality risk of PCI relative to CABG in patients with heart failure (HR, 1.75; 95% CI, 1.28-2.42; P<0.001) and no excess mortality risk in patients without heart failure (HR, 1.04; 95% CI, 0.80-1.34; P=0.77). Conclusions There was a significant interaction between heart failure and the mortality risk of PCI relative to CABG with excess risk in patients with heart failure and neutral risk in patients without heart failure.

Association Between Radial Versus Femoral Access for Percutaneous Coronary Intervention and Long-Term Mortality.

Background Percutaneous coronary intervention with radial arterial access has been associated with fewer occurrences of major bleeding. However, published data on the long-term mortality and major adverse cardiac events after percutaneous coronary intervention with radial or femoral arterial access are inconclusive. Method and Results This was a territory-wide retrospective cohort study including 26 022 patients who underwent first-ever percutaneous coronary intervention between January 1, 2010 and December 31, 2017 in Hong Kong. Among the 14 614 patients matched by propensity score (7307 patients in each group), 558 (7.6%) and 787 (10.8%) patients died during the observation period in the radial group and femoral group, respectively, resulting in annualized all-cause mortality rates of 2.69% and 3.87%, respectively. The radial group had a lower risk of all-cause mortality compared with the femoral group up to 3 years after percutaneous coronary intervention (hazard ratio [HR], 0.70; 95% CI, 0.63-0.78; P<0.001). Radial access was associated with a lower risk of major adverse cardiac events (HR, 0.78; 95% CI, 0.73-0.83, P<0.001), myocardial infarction after hospital discharge (HR, 0.78; 95% CI, 0.70-0.87, P<0.001), and unplanned revascularization (HR, 0.76; 95% CI, 0.68-0.85, P<0.001). The risks of stroke were similar across the 2 groups (HR, 0.96; 95% CI, 0.82-1.13, P=0.655). Conclusions Radial access was associated with a significant reduction in all-cause mortality at 3 years compared with femoral access. Radial access was associated with reduced risks of myocardial infarction and unplanned revascularization, but not stroke. The benefits were sustained beyond the early postoperative period.
