RESUMEN

BACKGROUND: Little is known about factors contributing to burnout and intent to leave in cardiologists and other cardiology health care workers. METHODS AND RESULTS: The Coping With COVID survey assessed work conditions, burnout, and intent to leave among physicians, nurses, advanced practice providers, and other clinical staff (OCS) from April 2020 to December 2020. Single-item measures assessed work conditions, burnout (emotional exhaustion), and intent to leave. Multilevel logistic regression examined work life variables' relationships to burnout among role types and feeling valued as a mediator. Open-ended comments analyzed via grounded theory contributed to a conceptual model. Coping With COVID was completed by 1199 US cardiology health care workers (354 physician/520 nurses/198 advanced practice providers/127 OCS). Nurses were most likely to report burnout (59% nurses, 57% OCS, 46% advanced practice providers, 40% physicians, P<0.0001). Workload correlated with burnout in all groups (adjusted odds ratios [aORs], 4.1-17.4; Ps<0.005), whereas anxiety/depression related to burnout in all except OCS (aORs, 3.9-8.3; Ps≤0.001). Feeling valued was related to lower burnout in most groups. Intent to leave was common (23%-45%) and was lower in physicians and advanced practice providers who felt valued (aORs, 0.26 and 0.22, respectively; Ps<0.05). Burnout was highest for nurses in practice 16 to 20 years, and intent to leave was highest for OCS in practice 16 to 20 years. Themes contributing to burnout included personal and patient safety, leadership, and financial issues. CONCLUSIONS: Burnout was prevalent among cardiology health care workers and highest in nurses and OCS. Addressing factors associated with burnout in different role types may improve work life sustainability for all cardiology health care workers.

RESUMEN

OBJECTIVE: To determine the impact of adverse social and behavioral determinants of health (SBDH) on health care use in a safety-net community hospital (SNCH) heart failure (HF) population. METHODS: We performed a retrospective analysis of HF patients at a single SNCH between 2018-2019 (N= 4594). RESULTS: At least one adverse SBDH was present in 21% of the study population. Patients with at least one adverse SBDH were younger (57 vs. 68 years), more likely to identify as Black (50% vs. 36%), be male (68% vs. 53%), and have Medicaid insurance (48% vs. 22%), p<.001. Presence of at least one adverse SBDH (homelessness, substance use, or incarceration) correlated with increased hospitalizations (2.3 vs 1.4/patient) and ED visits (5.1 vs 2.1/patient), p<.0001. Adverse SBDH were independent predictors of HF readmissions. Prescribing of guideline-directed medical therapy was similar among all patients. CONCLUSIONS: In a SNCH HF cohort, adverse SBDH predominantly afflict younger Black men on Medicaid and are associated with increased utilization.

RESUMEN

BACKGROUND: Balloon Tipped Temporary Pacemakers (BTTP) are the most used temporary pacemakers; however, they are associated with a risk of dislodgement and thromboembolism. Recently, Temporary Permanent Pacemakers (TPPM) have been increasingly used. Evidence of outcomes with TPPM compared to BTTP remains scarce. METHODS: Retrospective, chart review study evaluating all patients who underwent temporary pacemaker placement between 2014 and 2022 (N = 126) in the cardiac catheterization laboratory (CCL) at a level 1 trauma center. Primary outcome of this study is to evaluate the safety profile of TPPM versus BTTP. Secondary objectives include patient ambulation and healthcare utilization in patients with temporary pacemakers. RESULTS: Both groups had similar baseline characteristics distribution including gender, race, and age at temporary pacemaker insertion (p > .05). Subclavian vein was the most common site of access for the TPPM cohort (89.0%) versus the femoral vein in the BTTP group (65.1%). Ambulation was only possible in the TPPM group (55.6%, p < .001). Lead dislodgement, venous thromboembolism, local hematoma, and access site infections were less frequently encountered in the TPPM group (OR = 0.23 [95% CI (0.10-0.67), p < .001]). Within the subgroup of patients with TPPM, 36.6% of the patients were monitored outside the ICU setting. There was no significant difference in the pacemaker-related adverse events among patients with TPPM based on their in-hospital setting. CONCLUSION: TPPM is associated with a more favorable safety profile compared to BTTP. They are also associated with earlier patient ambulation and reduced healthcare utilization.

RESUMEN

INTRODUCTION: An arteriovenous fistula (AVF) in patients with end-stage kidney disease (ESKD) can influence flow states. We sought to evaluate if assessment of aortic stenosis (AS) by transthoracic echocardiographic (TTE) differs in the presence of AVF compared to other dialysis accesses in patients on dialysis. METHODS: We identified consecutive ESKD patients on dialysis and concomitant AS from a single center between January 2000 and March 2021. We analyzed TTE parameters of AS severity (velocities, gradients, aortic valve area [AVA]) and hemodynamics (cardiac output [CO], valvuloarterial impedance [Zva]) and compared AS parameters in patients with AVF versus other dialysis access. RESULTS: The cohort included 94 patients with co-prevalent ESKD and AS; mean age 66 years, 71% male; 43% Black, 24% severe AS. Dialysis access: 53% AVF, 47% others. In the overall cohort, no significant differences were noted between AVF versus non-AVF in AVA/CO/Zva, but with notable subgroup differences. In mild AS, CO was significantly higher in AVF versus non-AVF (6.3 vs. 5.2 L/min; p = .04). In severe AS, Zva was higher in the AVF versus non-AVF (4.6 vs. 3.6 mm Hg/mL/m2 ). With increasing AS severity in the AVF group, CO decreased, coupled with increase in Zva, likely counterbalancing the net hemodynamic impact of the AVF. CONCLUSION: Among ESKD patients with AS, TTE parameters of flow states and AS severity differed in those with AVF versus other dialysis accesses and varied with progression in severity of AS. Future longitudinal assessment of hemodynamic parameters in a larger cohort of co-prevalent ESRD and AS would be valuable.

RESUMEN

AIMS: This analysis evaluates whether proportional serial cardiac troponin (cTn) change predicts benefit from an early versus delayed invasive, or conservative treatment strategies across kidney function in non-ST-elevation acute coronary syndrome (NSTE-ACS). METHODS: Patients diagnosed with NSTE-ACS in the Veterans Health Administration between 1999 and 2022 were categorized into terciles (<20%, 20 to ≤80%, >80%) of proportional change in serial cTn. Primary outcome included mortality or rehospitalization for myocardial infarction at 6 and 12 months, in survivors of index admission. Adjusted hazard ratio (HR) with 95% confidence Intervals (95% confidence interval [CI]) were calculated for the primary outcome for an early invasive (≤24 h of the index admission), delayed invasive (>24 h of index admission to 90-days postdischarge), or a conservative management. RESULTS: Chronic kidney disease (CKD) was more prevalent (45.3%) in the lowest versus 42.2% and 43% in middle and highest terciles, respectively (p < 0.001). Primary outcome is more likely for conservative versus early invasive strategy at 6 (HR: 1.44, 95% CI: 1.37-1.50) and 12 months (HR: 1.44, 95% CI: 1.39-1.50). A >80% proportional change demonstrated HR (95% CI): 0.90 (0.83-0.97) and 0.93 (0.88-1.00; p = 0.041) for primary outcome at 6 and 12 months, respectively, when an early versus delayed invasive strategy was used, across CKD stages. CONCLUSIONS: Overall, the invasive strategy was safe and associated with improved outcomes across kidney function in NSTE-ACS. Additionally, >80% proportional change in serial troponin in NSTE-ACS is associated with benefit from an early versus a delayed invasive strategy regardless of kidney function. These findings deserve confirmation in randomized controlled trials.

RESUMEN

Background: The prevalence of advanced chronic kidney disease (CKD) is higher in Black than in White Americans. We evaluated CKD progression in Black and White participants and the contribution of biological risk factors. We included the study of lung function (measured by forced vital capacity [FVC]), which is part of the emerging notion of interorgan cross-talk with the kidneys to racial differences in CKD progression. Methods: This longitudinal study included 2175 Black and 2207 White adult Coronary Artery Risk Development in Young Adults (CARDIA) participants. Estimated glomerular filtration rate (eGFR) and urinary albumin-to-creatinine ratio (UACR) were measured at study year 10 (age 27-41y) and every five years for 20 years. The outcome was CKD progression through no CKD, low, moderate, high, or very high-risk categories based on eGFR and UACR in combination. The association between race and CKD progression as well as the contribution of risk factors to racial differences were assessed in multivariable-adjusted Cox models. Results: Black participants had higher CKD transition probabilities than White participants and more prevalent risk factors during the 20-year period studied. Hazard ratios for CKD transition for Black (vs White participants) were 1.38 from No CKD into ≥ low risk, 2.25 from ≤ low risk into ≥ moderate risk, and 4.49 from ≤ moderate risk into ≥ high risk. Racial differences in CKD progression from No CKD into ≥ low risk were primarily explained by FVC (54.8%), hypertension (30.9%), and obesity (20.8%). In contrast, racial differences were less explained in more severe transitions. Conclusion: Black participants had a higher risk of CKD progression, and this discrepancy may be partly explained by FVC and conventional risk factors.

RESUMEN

OBJECTIVES: We sought to study the association of renal impairment (RI) with mortality in ST-segment elevation myocardial infarction (STEMI) complicated by cardiogenic shock and/or cardiac arrest (CS/CA). METHODS: Patients with RI (estimated glomerular filtration rate <60 mL/min/1.73 m2 ) were identified from the Midwest STEMI consortium, a prospective registry of four large regional programs comprising consecutive patients over 17 years. Primary outcome was in-hospital and 1-year mortality stratified by RI status and presence of CS/CA among patients with STEMI referred for coronary angiography. RESULTS: In a cohort of 13,463 STEMI patients, 13% (n = 1754) had CS/CA, 30% (n = 4085) had RI. Overall, in-hospital mortality was 5% (12% RI vs. 2% no-RI, p < 0.001) and 1-year mortality 9% (21% RI vs. 4% no-RI, p < 0.001). Among uncomplicated STEMI, in-hospital mortality was 2% (4% RI vs. 1% no-RI, p < 0.001) and 1-year mortality 6% (13% RI vs. 3% no-RI, p < 0.001). In STEMI with CS/CA, in-hospital mortality was 29% (43% RI vs. 15% no-RI, p < 0.001) and 1-year mortality 33% (50% RI vs. 16% no-RI, p < 0.001). Using Cox proportional hazards, RI was an independent predictor of in-hospital mortality in STEMI with CS/CA (odds ratio [OR]: 3.86; confidence interval [CI]: 2.6, 5.8). CONCLUSIONS: The association of RI with in-hospital and 1-year mortality is disproportionately greater in those with CS/CA compared to uncomplicated STEMI presentations. Factors predisposing RI patients to higher risk STEMI presentations and pathways to promote earlier recognition in the chain of survival need further investigation.

RESUMEN

Transesophageal echocardiography is the gold-standard for evaluating potential central sources of thromboembolism. Despite its routine use and excellent safety profile, limitations exist in the ability to effectively assess the aortic arch and proximal descending aorta with this imaging modality. We herein present a case of a 59 year-old patient presenting with renal and splenic infarcts, without obvious cardioembolic source on echocardiography, who was found to have a large, mobile aortic thrombus on gated cardiac computed tomography.

RESUMEN

The 2022 US Preventive Services Task Force (USPSTF) recommendation notes that the decision to initiate daily aspirin therapy for primary prevention of cardiovascular disease (CVD) should be made on a case-by-case basis for adults ages 40 to 59 with a 10% or greater 10-year CVD risk. The recommendation applies to those without signs or symptoms of clinically evident CVD who are not at an increased risk of bleeding. Clinicians are encouraged to use their judgment in weighing the risks and benefits of aspirin therapy, while taking patient preference into account for patients ages 40 to 60.

RESUMEN

BACKGROUND: There may be nontraditional pathways of chronic kidney disease (CKD) progression that are complementary to classical pathways. Therefore, we aimed to examine nontraditional risk factors for incident CKD and its progression. METHODS: We used the generally healthy population (n = 4382) starting at age 27-41 years in the Coronary Artery Risk Development in Young Adults (CARDIA) cohort, which is an observational longitudinal study. Nontraditional risk factors included forced vital capacity, inflammation, serum urate, and serum carotenoids. CKD risk category was classified using the estimated glomerular filtration rate (eGFR) and urinary albumin-to-creatinine ratio (UACR) measured in 1995-1996 and repeated every 5 years for 20 years: No CKD, low risk, moderate risk, high risk, and very high risk. RESULTS: At baseline, 84.8% had no CKD (eGFR ≥60 mL/min/1.73 m2 and UACR <10 mg/g), 10.3% were in the low risk (eGFR ≥60 and UACR 10-29), and 4.9% had CKD (eGFR <60 and/or UACR ≥ 30). Nontraditional risk factors were significantly associated with the progression of CKD to higher categories. Hazard ratios per standard deviation of the predictor for incident CKD and its progression from the No CKD and low and moderate risk into CKD were inverse for forced vital capacity and serum carotenoids and positive for serum urate, GlycA, and C-reactive protein, the first 3 even after adjustment for conventional risk factors. CONCLUSION: Several nontraditional markers were significantly associated with an increased risk of progression to higher CKD categories in generally healthy young to middle-aged adults.

RESUMEN

Warfarin is the only approved anticoagulant after mechanical valve replacement, but it is a well described risk factor for calciphylaxis among patients with end-stage kidney disease. Our patient with end-stage kidney disease rapidly developed calciphylaxis after dual mechanical valve replacement in association with warfarin initiation, posing significant challenges in clinical management and a fatal outcome. (Level of Difficulty: Intermediate.).

RESUMEN

Background Previous studies of worsening chronic kidney disease (CKD) based on declining estimated glomerular filtration rate (eGFR) or increasing urine albumin-creatinine ratio (UACR) are limited to later middle-age and older adults. We examined associations of CKD progression and incident cardiovascular disease (CVD) and mortality in younger adults. Methods and Results We studied 4382 adults in CARDIA (Coronary Artery Risk Development in Young Adults) initially aged 27 to 41 years and prospectively over 20 years. Five-year transition probabilities across CKD risk categories were based on eGFR and UACR measured at each exam. Proportional hazards models predicted incident CVD and all-cause mortality by time-varying CKD risk category, adjusting for demographics and CVD risk factors. Progression of CKD risk categories over 20 years occurred in 28.7% (1256/4382) of participants, driven by increases in UACR, but including 5.8% (n=255) with eGFR<60 mL/min per 1.73 m2 or UACR ≥300 mg/g. Compared with eGFR ≥60 and UACR <10, demographic and smoking-adjusted hazard ratios for CVD were 1.62 (95% CI, 1.21-2.18) for low CKD risk (eGFR ≥60 with UACR 10-29) and 13.65 (95% CI, 7.52-24.79) for very high CKD risk (eGFR <30 or eGFR 30-44 with UACR 30-299; or eGFR 30-59 with UACR ≥300). Corresponding hazard ratios for all-cause mortality were 1.42 (95% CI, 1.08-1.88) and 14.75 (95% CI, 9.97-21.82). Although CVD associations were attenuated after adjustment for mediating CVD risk factors, all-cause mortality associations remained statistically significant. Conclusions Among young to middle-aged adults, progression to higher CKD risk category was common. Routine monitoring eGFR and UACR holds promise for prevention of CVD and total mortality.

RESUMEN

OBJECTIVES: We sought to evaluate interobserver concordance among experienced electrocardiogram (ECG) readers in predicting acute thrombotic coronary occlusion (ATCO) in the context of abnormal metabolic milieu (AMM) following resuscitated out of hospital cardiac arrest (OHCA). METHODS: OHCA patients with initial shockable rhythm who underwent invasive coronary angiography (ICA) were included. AMM was defined as one of: pH < 7.1, lactate > 2 mmol/L, serum potassium < 2.8 or >6.0 mEq/L. The initial ECG following ROSC but prior to ICA was adjudicated by 2 experienced readers using classic ST elevation myocardial infarction [STEMI] and expanded criteria and their combination to predict ATCO on ICA. RESULTS: 152 consecutive patients (mean age 58 years, 76% male) met inclusion criteria. AMM was present in 77%; and 42% had ATCO on ICA. Sensitivity, specificity, PPV, NPV using classic STEMI criteria were 50%, 98%, 94%, 72% (c-statistic 0.74); whereas for combined (STEMI + expanded) criteria they were 69%, 88%, 81%, 79% respectively (c-statistic 0.79). Inter-observer agreement (kappa) was 0.7 for classic STEMI criteria, and 0.66 for combined criteria. Agreement between readers was consistently higher when ATCO was absent and with NMM (kappa 0.78), but lower in AMM (kappa 0.6). CONCLUSIONS: Despite experienced ECG readers, there was only modest overall concordance in predicting ATCO in the context of resuscitated OHCA. Significant interobserver variations were noted dependent on metabolic milieu and angiographic ATCO. These observations fundamentally question the role of the 12-lead ECG as primary triaging tool for early angiography among patients with OHCA.

RESUMEN

BACKGROUND: Rheumatic heart disease affects 33 million people in low and middle income countries and is the leading cause of cardiovascular death among children and young adults. Evidence increasingly supports that simplified screening protocols can identify at risk children with good accuracy. One of the more proximal and pragmatic hurdles that has not been completely explored is the time required for executing the screening exam. METHODS: We conducted an observational study comparing three different echocardiographic strategies in four separate school-based screening programs in Kenya and Cameroon. RESULTS: In a sample of 911 children, we found that a single-view screening strategy can be obtained in an average time of 1.2 min/child, the two-view in an average of 2.1 min/child, and multi-view in an average of 5 min/child. CONCLUSIONS: Our study demonstrates that there are significant differences in the time required to execute different screening protocols and is an essential consideration in the feasibility of large scale populations based rheumatic heart disease screening programs.

RESUMEN

Chronic kidney disease and coronary artery disease are co-prevalent conditions with unique epidemiological and pathophysiological features, that culminate in high rates of major adverse cardiovascular outcomes, including all-cause mortality. This review outlines a summary of the literature, and nuances pertaining to non-invasive risk assessment of this population, medical management options for coronary heart disease and coronary revascularisation. A collaborative heart-kidney team-based approach is imperative for critical management decisions for this patient population, especially coronary revascularisation; this review outlines specific periprocedural considerations pertaining to coronary revascularisation, and provides a proposed algorithm for approaching revascularisation choices in patients with end-stage kidney disease based on available literature.

RESUMEN

Background Occlusion myocardial infarctions (OMIs) of the posterolateral walls are commonly missed by ST-segment-elevation myocardial infarction (STEMI) criteria, with >50% of patients with circumflex occlusion not receiving emergent reperfusion and experiencing increased mortality. ST-segment depression maximal in leads V1-V4 (STDmaxV1-4) has been suggested as an indicator of posterior OMI. Methods and Results We retrospectively reviewed a high-risk population with acute coronary syndrome. OMI was defined from prior studies as a culprit lesion with TIMI (Thrombolysis in Myocardial Infarction) 0 to 2 flow or TIMI 3 flow plus peak troponin T >1.0 ng/mL or troponin I >10 ng/mL. STEMI was defined by the Fourth Universal Definition of Myocardial Infarction. ECGs were interpreted blinded to outcomes. Among 808 patients, there were 265 OMIs, 108 (41%) meeting STEMI criteria. A total of 118 (15%) patients had "suspected ischemic" STDmaxV1-4, of whom 106 (90%) had an acute culprit lesion, 99 (84%) had OMI, and 95 (81%) underwent percutaneous coronary intervention. Suspected ischemic STDmaxV1-4 had 97% specificity and 37% sensitivity for OMI. Of the 99 OMIs detected by STDmaxV1-4, 34% had <1 mm ST-segment depression, and only 47 (47%) had accompanying STEMI criteria, of which 17 (36%) were identified a median 1.00 hour earlier by STDmaxV1-4 than STEMI criteria. Despite similar infarct size, TIMI flow, and coronary interventions, patients with STEMI(-) OMI and STDmaxV1-4 were less likely than STEMI(+) patients to undergo catheterization within 90 minutes (46% versus 68%; P=0.028). Conclusions Among patients with high-risk acute coronary syndrome, the specificity of ischemic STDmaxV1-4 was 97% for OMI and 96% for OMI requiring emergent percutaneous coronary intervention. STEMI criteria missed half of OMIs detected by STDmaxV1-4. Ischemic STDmaxV1-V4 in acute coronary syndrome should be considered OMI until proven otherwise.

RESUMEN

OBJECTIVES: The aim of this study was to compare 5-year cardiovascular, renal, and bioprosthetic valve durability outcomes in patients with severe aortic stenosis (AS) and chronic kidney disease (CKD) undergoing transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR). BACKGROUND: Patients with severe AS and CKD undergoing TAVR or SAVR are a challenging, understudied clinical subset. METHODS: Intermediate-risk patients with moderate to severe CKD (estimated glomerular filtration rate <60 mL/min/m2) from the PARTNER (Placement of Aortic Transcatheter Valve) 2A trial (patients randomly assigned to SAPIEN XT TAVR or SAVR) and SAPIEN 3 Intermediate Risk Registry were pooled. The composite primary outcome of death, stroke, rehospitalization, and new hemodialysis was evaluated using Cox regression analysis. Patients with and without perioperative acute kidney injury (AKI) were followed through 5 years. A core laboratory-adjudicated analysis of structural valve deterioration and bioprosthetic valve failure was also performed. RESULTS: The study population included 1,045 TAVR patients (512 SAPIEN XT, 533 SAPIEN 3) and 479 SAVR patients. At 5 years, SAVR was better than SAPIEN XT TAVR (52.8% vs 68.0%; P = 0.04) but similar to SAPIEN 3 TAVR (52.8% vs 58.7%; P = 0.89). Perioperative AKI was more common after SAVR than TAVR (26.3% vs 10.3%; P < 0.001) and was independently associated with long-term outcomes. Compared with SAVR, bioprosthetic valve failure and stage 2 or 3 structural valve deterioration were significantly greater for SAPIEN XT TAVR (P < 0.05) but not for SAPIEN 3 TAVR. CONCLUSIONS: In intermediate-risk patients with AS and CKD, SAPIEN 3 TAVR and SAVR were associated with a similar risk for the primary endpoint at 5 years. AKI was more common after SAVR than TAVR, and SAPIEN 3 valve durability was comparable with that of surgical bioprostheses.
