RESUMEN
Aims: Patients with autoimmune connective tissue diseases (CTDs) have a high burden of valvular heart disease and are often thought of as high surgical risk patients. Methods and results: Patients undergoing aortic valve replacement (AVR) were identified in the Nationwide Readmissions Database between January 2012 and December 2018. Patients with a history of systemic lupus erythematosus, rheumatoid arthritis, systemic sclerosis, mixed C, Sjögren syndrome, polymyositis, and dermatomyositis were included in the CTD cohort. Patients undergoing coronary artery bypass grafting concomitantly with AVR were excluded. A total of 569 600 hospitalizations were included, of which16 531 (2.9%) had CTD. CTD patients were more likely to be females, with higher rates of heart failure, pulmonary hypertension, and more likely to be insured by Medicare. CTD patients had lower mortality than non-CTD patients [odds ratio (OR) 0.66; 95% confidence interval (CI): 0.59-0.74] and stroke [OR 0.87; 95% (CI): 0.79-0.97]. CTD patients undergoing SAVR had lower mortality [OR 0.69; 95% (CI): 0.60-0.80] and stroke [OR 0.86; 95% (CI): 0.75-0.98). CTD patients undergoing TAVR had lower mortality outcomes [OR 0.67; 95% (CI): 0.56-0.80]; however, they had comparable stroke outcomes [OR 0.97; 95% (CI): 0.83-1.13, P = 0.69]. Conclusions: Outcomes for patients with CTD requiring AVR are not inferior to their non-CTD counterparts. A comprehensive heart team selection of patients undergoing AVR approaches should place CTD history under consideration; however, pre-existing CTD should not be prohibitive of AVR interventions.
RESUMEN
Outpatient follow-up after hospital discharge improves continuity of care and reduces readmissions, but rates of follow-up remain low. It is not known whether electronic medical record (EMR)-based tools improve follow-up. The aim of this study was to determine if an EMR-based order to secure cardiology follow-up appointments at hospital discharge would improve follow-up rates and hospital readmission rates. A pre-post interventional study was conducted and evaluated 39,209 cardiovascular medicine discharges within an academic center between 2012 and 2017. Follow-up rates and readmission rates were compared during 2 years prior to EMR-order implementation (pre-order era 2012-2013, n = 12,852) and 4 years after implementation (EMR-order era 2014-2017, n = 26,357). The primary endpoint was 90-day cardiovascular follow-up rates within our health system. In the overall cohort, the mean age of patients was 69.3 years [SD 14.7] and 60.7% (n = 23,827) were male. In the pre-order era, 90-day follow-up was 56.7 ± 0.4% (7286 of 12,852) and increased to 67.9 ± 0.3% (17,888 of 26,357, P < 0.001) in the EMR-order era. The use of the EMR follow-up order was independently associated with increased outpatient follow-up within 90 days after adjusting for patient demographics and payor status (OR 3.28, 95% CI 3.10-3.47, P < 0.001). The 30-day readmission rate in the pre-order era was 12.8% (1642 of 12,852) compared with 13.7% (3601 of 26,357, P = 0.016) in the EMR-order era. An EMR-based appointment order for follow-up appointment scheduling was associated with increased cardiovascular medicine follow-up, but was not associated with an observed reduction in 30-day readmission rates.
RESUMEN
Introduction: Patients with end stage liver disease (ESLD) have a hyperdynamic state due to decreased systemic vascular resistance and increased cardiac output. Preoperative evaluation with dobutamine stress echocardiography (DSE) is used to risk-stratify patients prior to liver transplant. We sought to identify the impact of inducible left ventricular outflow tract obstruction (LVOTO) on DSE on post-operative liver transplant outcomes. Methods: Patients with ESLD who underwent liver transplant at Cleveland Clinic between January 2007 and August 2016 were identified. Pre-operative DSE data, and post-operative intensive care unit (ICU) data were extracted. Patients with inducible LVOTO were compared to those without LVOTO. Results: Of the 515 patients identified who underwent DSE prior to liver transplant, 165 (30%) were female, and 95 (18%) had LVOTO. There were no major differences in baseline characteristics between the two groups. In the LVOTO group, rest gradients were 10.8 ± 3 mm Hg while peak gradients were 90 ± 48.2 mm Hg. No significant differences in ICU length of stay or duration of mechanical ventilation between both groups were noted. There were 21 deaths at 30 days. There were 2 (2.1%) deaths in the LVOTO group, versus 19 (4.5%) deaths in the non LVOTO group (p = 0.28). Higher Model for End Stage Liver Disease (MELD) scores predicted longer duration of mechanical ventilation and ICU length of stay. Conclusion: Inducible LVOTO on DSE does not adversely affect the short-term outcomes post liver transplant. Presence of inducible LVOTO should not be the mere reason to deny liver transplant among patients with ESLD.
RESUMEN
AIMS: Post cardiac surgery atrial fibrillation (POAF) is common, with adverse implications. However, relatively little is known regarding the time varying nature of risk factors associated with POAF. We describe variation in POAF along with its associated risk factors. METHODS: Medical records of adult patients undergoing cardiac valve surgery from 2003-13, without a history of pre-operative AF were analyzed retrospectively. POAF was adjudicated using inpatient and outpatient electrocardiograms (EKG). Risk of AF over time along with time-varying risk factors were estimated using multiphase non-linear logistic mixed effects model. RESULTS: 10,461 patients with 100,149 EKGs were analyzed [median follow-up 4 months (IQR 48 hours-2 years)]. AF prevalence changed with time since surgery and two distinct phases were identified. Prevalence peaked to 13% at 2 weeks (early phase) and 9% near 7 years post-operatively (late phase). Older age, greater severity of preoperative tricuspid valve (TV) regurgitation, mitral valve replacement and prior cardiac surgery were time-independent risk factors for POAF. TV repair was associated with a decreased risk of early phase POAF. Pre-operative blood urea nitrogen, peripheral vascular disease and hypertension were associated with a higher risk of late phase POAF. CONCLUSIONS: POAF risk shows two distinct phases with an early peak and a late gradual rise, each associated with a different set of risk factors.
RESUMEN
BACKGROUND: The importance of a coronary artery, based on the myocardial mass it perfuses, is well documented, but little is known about the importance of a vessel that has been bypassed and its effect on survival in the context of bilateral internal thoracic artery (BITA) grafting. OBJECTIVES: This study determined the effect of a dominant left anterior descending (LAD) artery and important non-LAD targets on outcomes after BITA grafting. METHODS: From January 1972 to January 2011, of 6,127 patients who underwent BITA grafting, 2,551 received 1 ITA grafted to the LAD and had an evaluable coronary angiogram. A dominant LAD was defined as one that was wrapped around the left ventricular apex. Non-LAD targets were graded based on their terminal reach toward the apex: important: >75% (n = 1,698); and less important: ≤75% (n = 853). Mean follow-up was 14 ± 8.7 years. Multivariable analysis was performed to identify risk factors for time-related mortality. RESULTS: A dominant LAD was present more frequently in patients with less important additional targets (51% vs. 35%; p < 0.0001). A total of 179 patients (7.0%) received a second ITA to multiple targets, 77 (43%) of which were to multiple important target vessels. Unadjusted late survival was similar regardless of degree of importance of the second ITA target-77% at 15 years (p = 0.70) for the important and less important targets, respectively. In the multivariable model, grafting the second ITA to multiple important targets was associated with better long-term survival (p = 0.005). In patients with a nondominant LAD, a second ITA grafted to a less important artery was associated with higher risk of operative mortality (2.4% vs. 0.51%; p = 0.007). A saphenous vein graft to an important or less important target did not influence long-term survival. CONCLUSIONS: In BITA grafting, bypassing multiple important targets to maximize myocardium supplied by ITAs improved long-term survival. In patients with a nondominant LAD, selecting an important target for the second ITA lowered operative mortality.

BACKGROUND: Little is known about the role of left atrial appendage closure using the Watchman device (Boston Scientific) in patients who are at very high risk for stroke. OBJECTIVE: The purpose of this study was to assess the role of Watchman in patients with CHA2DS2-VASc ≥5. METHODS: All patients undergoing procedures for Watchman implant at our institution were enrolled in a prospective registry. All 104 consecutive recipients with CHA2DS2-VASc ≥5 were included. RESULTS: Median patient age was 78.5 ± 6.4 years, 56% were male, mean CHA2DS2-VASc was 5.7 ± 0.9, and mean HASBLED was 4.0 ± 1.0. Indications for implantation were significant prior bleeding (73%), unacceptable bleeding risk (21%), and unacceptable stroke and bleeding risk (6%). Watchman implantation was successful in all patients. All but 2 patients completed 45 days of postprocedural anticoagulation; 56% used warfarin and 44% used a novel oral anticoagulant. Transesophageal echocardiogram at 45 days revealed no significant peridevice leak. One patient was found to have a small mobile, filamentous echodensity attached on the medial aspect of the Watchman device. This resolved with longer anticoagulation with dabigatran and did not result in adverse outcome. At 1-year follow up, ischemic stroke had occurred in 3 patients (2.8%) at 96, 119, and 276 days after the procedure. CONCLUSION: In a population of patients with mean CHA2DS2-VASc of 5.7, Watchman implantation seemed to be safe and efficacious, with a residual annual ischemic stroke risk of 2.8%. In an atrial fibrillation population with a similar CHA2DS2-VASc score, the estimated annual risk of stroke is ≈12% off anticoagulation and >4% on warfarin.

BACKGROUND: Systems to improve ST-segment-elevation myocardial infarction (STEMI) care have traditionally focused on improving door-to-balloon time. However, prompt guideline-directed medical therapy and transradial primary percutaneous coronary intervention (PCI) are also associated with reduced STEMI mortality. The incremental prognostic value of each facet of STEMI care on clinical outcomes within a STEMI system of care is unknown. METHODS AND RESULTS: We implemented systems-based strategies at our hospital to improve 3 STEMI care metrics: (1) prompt guideline-directed medical therapy before sheath insertion for PCI, (2) use of transradial primary PCI, and (3) door-to-balloon time. We assessed the incremental association of metrics achieved with in-hospital adverse events and 30-day mortality. Of 1272 consecutive patients with STEMI treated with PCI at our hospital (January 1, 2011, to December 31, 2016), the percentage with achievement of zero, 1, 2, or 3 STEMI care metrics was 7.1%, 24.1%, 43.8%, and 25.1%; and 30-day mortality was 15.6%, 8.6%, 3.6%, and 3.2%, respectively (log-rank P<0.001). After adjusting for known clinical predictors of STEMI in-hospital mortality, achievement of at least 2 STEMI care metrics was associated with significantly reduced in-hospital mortality (odds ratio, 0.39; 95% CI, 0.16-0.96; P=0.041). Each metric provided incremental prognostic value when modeled in stepwise order of their occurrence in clinical practice (final model C statistic, 0.677; P<0.001). CONCLUSIONS: Prompt guideline-directed medical therapy before sheath insertion for PCI, transradial primary PCI, and door-to-balloon time add incremental prognostic value in STEMI care. Expanding STEMI systems of care from a singular focus on door-to-balloon time to a comprehensive focus on multifaceted STEMI care offers an opportunity to further improve STEMI outcomes.

BACKGROUND: The safety of nonsteroidal anti-inflammatory drug (NSAID) and aspirin coadministration is uncertain. OBJECTIVES: The aim of this study was to compare the safety of combining NSAIDs with low-dose aspirin. METHODS: This analysis of the PRECISION (Prospective Randomized Evaluation of Celecoxib Integrated Safety Versus Ibuprofen or Naproxen) trial included 23,953 patients with osteoarthritis or rheumatoid arthritis at increased cardiovascular risk randomized to celecoxib, ibuprofen, or naproxen. The on-treatment population was used for this study. Outcomes included composite major adverse cardiovascular events, noncardiovascular death, gastrointestinal or renal events, and components of the composite. Cox proportional hazards models compared outcomes among NSAIDs stratified by aspirin use following propensity score adjustment. Kaplan-Meier analysis was used to compare the cumulative probability of events. RESULTS: When taken without aspirin, naproxen or ibuprofen had greater risk for the primary composite endpoint compared with celecoxib (hazard ratio [HR]: 1.52; 95% confidence interval [CI]: 1.22 to 1.90, p <0.001; and HR: 1.81; 95% CI: 1.46 to 2.26; p <0.001, respectively). Compared with celecoxib, ibuprofen had more major adverse cardiovascular events (p < 0.05), and both ibuprofen and naproxen had more gastrointestinal (p < 0.001) and renal (p < 0.05) events. Taken with aspirin, ibuprofen had greater risk for the primary composite endpoint compared with celecoxib (HR: 1.27; 95% CI: 1.06 to 1.51; p < 0.01); this was not significantly higher with naproxen (HR: 1.18; 95% CI: 0.98 to 1.41; p = 0.08). Among patients on aspirin, major adverse cardiovascular events were similar among NSAIDs, and compared with celecoxib, ibuprofen had more gastrointestinal and renal events (p < 0.05), while naproxen had more gastrointestinal events (p < 0.05), without a difference in renal events. Similar results were seen on adjusted Kaplan-Meier analysis. CONCLUSIONS: Celecoxib has a more favorable overall safety profile than naproxen or ibuprofen when taken without aspirin. Adding aspirin attenuates the safety advantage of celecoxib, although celecoxib is still associated with fewer gastrointestinal events than ibuprofen or naproxen and fewer renal events than ibuprofen.

BACKGROUND: Women with ST-segment elevation myocardial infarction (STEMI) receive suboptimal care and have worse outcomes than men. Whether strategies to reduce STEMI care variability impact disparities in the care and outcomes of women with STEMI is unknown. OBJECTIVES: The study assessed the care and outcomes of men versus women with STEMI before and after implementation of a comprehensive STEMI protocol. METHODS: On July 15, 2014, the authors implemented: 1) emergency department catheterization lab activation; 2) STEMI Safe Handoff Checklist; 3) immediate transfer to an immediately available catheterization lab; and 4) radial first approach to percutaneous coronary intervention (PCI). The authors prospectively studied consecutive patients with STEMI and assessed guideline-directed medical therapy (GDMT) before PCI, median door-to-balloon time (D2BT), in-hospital adverse events, and 30-day mortality stratified by sex before (January 1, 2011 to July 14, 2014; control group) and after (July 15, 2014 to December 31, 2016) implementation of the STEMI protocol. RESULTS: Of 1,272 participants (68% men, 32% women), women were older with more comorbidities than men. In the control group, women had less GDMT (77% vs. 69%; p = 0.019) and longer D2BT (median 104 min; [interquartile range (IQR): 79 to 133] min vs. 112 [IQR: 85 to 147] min; p = 0.023). Women had more in-hospital stroke, vascular complications, bleeding, transfusion, and death. In the comprehensive 4-step STEMI protocol, sex disparities in GDMT (84% vs. 80%; p = 0.32), D2BT (89 [IQR: 68 to 106] min vs. 91 [IQR: 68 to 114] min; p = 0.15), and in-hospital adverse events resolved. The absolute sex difference in 30-day mortality decreased from the control group (6.1% higher in women; p = 0.002) to the comprehensive 4-step STEMI protocol (3.2% higher in women; p = 0.090). CONCLUSIONS: A systems-based approach to STEMI care reduces sex disparities and improves STEMI care and outcomes in women.

BACKGROUND: In the SYNTAX (Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery) trial, patients with 3-vessel or left main coronary artery disease (CAD) had improved long-term outcomes with coronary artery bypass graft (CABG) surgery compared with percutaneous coronary intervention (PCI) with drug-eluting stents (DES), improvements driven mainly by differences in myocardial infarction and repeat revascularization. OBJECTIVES: This study compared the long-term quality-of-life benefits of DES-PCI versus CABG for patients with 3-vessel or left main CAD. METHODS: Between 2005 and 2007, the SYNTAX trial randomized 1,800 patients with 3-vessel or left main CAD to either CABG or DES-PCI. Health status was assessed at baseline and at 1, 6, 12, 36, and 60 months by using the Seattle Angina Questionnaire (SAQ) and the 36-Item Short Form Health Survey. RESULTS: At 5-year follow-up, CABG was superior to DES-PCI on several SAQ domains including angina frequency and physical function, as well as the role physical and role emotional scales of the 36-Item Short Form Health Survey. Subgroup analysis demonstrated a significant interaction between angiographic complexity (as assessed by the SYNTAX score) and angina relief (mean difference in the SAQ angina frequency score for CABG vs. PCI of -0.9, 3.3, and 3.9 points for low, intermediate, and high SYNTAX score patients, respectively; p = 0.048 for interaction). CONCLUSIONS: Among patients with 3-vessel or left main CAD, both CABG and DES-PCI were associated with substantial and sustained quality-of-life benefits over 5 years of follow-up. In general, CABG resulted in greater angina relief, although the absolute treatment benefit was small. Angina relief at 5 years was enhanced with CABG among patients with high SYNTAX scores, a finding reinforcing the recommendation that CABG should be strongly preferred for such patients.

AIMS: Recent cost-effectiveness analyses of percutaneous coronary intervention (PCI) versus coronary artery bypass grafting (CABG) have been limited by a short time horizon or were restricted to the US healthcare perspective. We, therefore, used individual patient-level data from the SYNTAX trial to evaluate the cost-effectiveness of PCI versus CABG from a European (Dutch) perspective. METHODS AND RESULTS: Between 2005 and 2007, 1800 patients with three-vessel or left main coronary artery disease were randomised to either CABG (n=897) or PCI with drug-eluting stents (DES; n=903). Costs were estimated for all patients based on observed healthcare resource usage over 5â years of follow-up. Health state utilities were evaluated with the EuroQOL questionnaire. A patient-level microsimulation model based on Dutch life-tables was used to extrapolate the 5-year in-trial data to a lifetime horizon. Although initial procedural costs were lower for CABG, total initial hospitalisation costs per patient were higher (17â 506 vs 14â 037, p<0.001). PCI was more costly during the next 5â years of follow-up, due to more frequent hospitalisations, repeat revascularisation procedures and higher medication costs. Nevertheless, total 5-year costs remained 2465/patient higher with CABG. When the in-trial results were extrapolated to a lifetime horizon, CABG was projected to be economically attractive relative to DES-PCI, with gains in both life expectancy and quality-adjusted life expectancy. The incremental cost-effectiveness ratio (ICER) (5390/quality-adjusted life year (QALY) gained) was favourable and remained <80â 000/QALY in >90% of the bootstrap replicates. Outcomes were similar when incorporating the prognostic impact of non-fatal myocardial infarction and stroke, as well as across a broad range of assumptions regarding the effect of CABG on post-trial survival and costs. However, DES-PCI was economically dominant compared with CABG in patients with a SYNTAX Score ≤22 or in those with left main disease. In patients for whom the SYNTAX Score II favoured PCI based on lower predicted 4-year mortality, PCI was also economically dominant, whereas in those patients for whom the SYNTAX Score II favoured surgery, CABG was highly economically attractive (ICER range, 2967 to 3737/QALY gained). CONCLUSIONS: For the broad population with three-vessel or left main disease who are candidates for either CABG or PCI, we found that CABG is a clinically and economically attractive revascularisation strategy compared with DES-PCI from a Dutch healthcare perspective. The cost-effectiveness of CABG versus PCI differed according to several anatomic factors, however. The newly developed SYNTAX Score II provides enhanced prognostic discrimination in this population, and may be a useful tool to guide resource allocation as well.

OBJECTIVES: To assess the perceptions of patients with stable coronary artery disease of the urgency and benefits of elective percutaneous coronary intervention and to examine how they vary across centers and by providers. DESIGN: Cross sectional study. SETTING: 10 US academic and community hospitals performing percutaneous coronary interventions between 2009 and 2011. PARTICIPANTS: 991 patients with stable coronary artery disease undergoing elective percutaneous coronary intervention. MAIN OUTCOME MEASURES: Patients' perceptions of the urgency and benefits of percutaneous coronary intervention, assessed by interview. Multilevel hierarchical logistic regression models examined the variation in patients' understanding across centers and operators after adjusting for patient characteristics, using median odds ratios. RESULTS: The most common reported benefits from percutaneous coronary intervention were to extend life (90%, n=892; site range 80-97%) and to prevent future heart attacks (88%, n=872; site range 79-97%). Although nearly two thirds of patients (n=661) reported improvement of symptoms as a benefit of percutaneous coronary intervention (site range 52-87%), only 1% (n=9) identified this as the only benefit. Substantial variability was noted in the ways informed consent was obtained at each site. After adjusting for patient and operator characteristics, the median odds ratios showed significant variation in patients' perceptions of percutaneous coronary intervention across sites (range 1.4-3.1) but not across operators within a site. CONCLUSION: Patients have a poor understanding of the benefits of elective percutaneous coronary intervention, with significant variation across sites. No sites had a high proportion of patients accurately understanding the benefits. Coupled with the wide variability in the ways in which hospitals obtain informed consent, these findings suggest that hospital level interventions into the structure and processes of obtaining informed consent for percutaneous coronary intervention might improve patient comprehension and understanding.

BACKGROUND: The Synergy Between Percutaneous Coronary Intervention With TAXUS and Cardiac Surgery (SYNTAX) trial demonstrated that in patients with 3-vessel or left main coronary artery disease, coronary artery bypass graft surgery (CABG) was associated with a lower rate of cardiovascular death, myocardial infarction, stroke, or repeat revascularization compared with percutaneous coronary revascularization with drug-eluting stents (DES-PCI)). The long-term cost-effectiveness of these strategies is unknown. METHODS AND RESULTS: Between 2005 and 2007, 1800 patients with left main or 3-vessel coronary artery disease were randomized to CABG (n=897) or DES-PCI (n=903). Costs were assessed from a US perspective, and health state utilities were evaluated with the EuroQOL questionnaire. A patient-level microsimulation model based on the 5-year in-trial data was used to extrapolate costs, life expectancy, and quality-adjusted life expectancy over a lifetime horizon. Although initial procedural costs were $3415 per patient lower with CABG, total hospitalization costs were $10 036 per patient higher. Over the next 5 years, follow-up costs were higher with DES-PCI as a result of more frequent hospitalizations, revascularization procedures, and higher medication costs. Over a lifetime horizon, CABG remained more costly than DES-PCI, but the incremental cost-effectiveness ratio was favorable ($16 537 per quality-adjusted life-year gained) and remained <$20 000 per quality-adjusted life-year in most bootstrap replicates. Results were consistent across a wide range of assumptions about the long-term effect of CABG versus DES-PCI on events and costs. In patients with left main disease or a SYNTAX score ≤22, however, DES-PCI was economically dominant compared with CABG, although these findings were less certain. CONCLUSIONS: For most patients with 3-vessel or left main coronary artery disease, CABG is a clinically and economically attractive revascularization strategy compared with DES-PCI. However, among patients with less complex disease, DES-PCI may be preferred on both clinical and economic grounds. CLINICAL TRIAL REGISTRATION URL: www.clinicaltrials.gov.

Many patients undergo elective coronary angiography without preprocedural stress testing that may be suitable if performed in patients with more angina pectoris or more frequently identified obstructive coronary artery disease (CAD). Patients in the National Cardiovascular Data Registry CathPCI Registry undergoing elective coronary angiography from July 2009 to April 2013 were assessed for differences in angina (Canadian Cardiovascular Society [CCS] class) and severity of obstructive CAD in those with and without preprocedural stress testing, stratified by CAD history. Given the large sample size, differences were considered clinically meaningful if the standardized difference (SD) was >10%. Of 790,601 patients without CAD history, 36.9% did not undergo preprocedural stress testing. Compared with patients with preprocedural stress testing, patients without preprocedural stress testing were more frequently angina free (CCS class 0; 28.2% with stress test vs 38.5% without, SD = 14.8%) and had similar rates of obstructive CAD (40.1% with stress test vs 35.7% without, SD = 9.0). Of 449,579 patients with CAD history, 44.2% did not undergo preprocedural stress testing. Patients without preprocedural stress testing reported more angina (CCS class III/IV angina: 17.8% vs 13.4%; SD = 11.3%) but were not more likely to have obstructive CAD (78.7% vs 81.1%; SD = 5.8%) than patients with preprocedural stress testing. In conclusion, approximately 40% of patients undergoing elective coronary angiography did not have preprocedural risk stratification with stress testing. For these patients, the clinical decision to proceed directly to invasive evaluation was not driven primarily by severe angina and did not result in higher detection rates for obstructive CAD.
