RESUMO
This single-center, observational study assessed the impact of age, gender, and body mass index (BMI) in patients with cardiogenic shock (CS) on temporary mechanical circulatory support. All adult patients admitted to the Cleveland Clinic main campus Cardiac Intensive Care Unit (CICU) between December 1, 2015, to December 31, 2019, CICU with CS necessitating mechanical circulatory support (MCS) with intra-aortic balloon pump, Impella, or venous arterial-extra corporeal membrane oxygenation were retrospectively analyzed for this study. Baseline characteristics and 30-day outcomes were collected through physician-directed chart review. The impact of age, gender, and BMI on 30-day mortality was assessed using multivariable logistic regression. Kaplan-Meier survival curves were used to analyze the survival difference in specific subsets. A total of 393 patients with CS on temporary MCS were admitted to our CICU during the study period. The median age of our cohort was 63 years (interquartile range 54 to 70 years), median BMI was 28.50 kg/m2 (interquartile range 24.62 to 29.72) and 70% (n = 276) were men. In total, 22 patients >80 years had received MCS compared with 372 patients <80 years. Patients >80 years on MCS had significantly higher 30-day mortality compared with those <80 years (81.8% vs 49.3%, p = 0.006). Upon stratifying patients by BMI, 161 (41%) patients were found to have BMI ≥30 kg/m2 whereas 232 (59%) patients had BMI <30 kg/m2. Comparison of 30-day mortality revealed that patients with BMI ≥30 did significantly worse than patients with BMI <30 (59.6% vs 45.3%, p = 0.007). There was no difference in 30-day mortality between men and women. On multivariable logistic regression, both age and BMI had a positive linear relation with adjusted 30-day mortality whereas gender did not have a major effect. Advanced age and higher BMI are independently associated with worse outcomes in patients with CS on MCS. Utilizing a strict selection criterion for patients in CS is pertinent to derive the maximum benefit from advanced mechanical support.

Guidewire retention after intravascular catheter insertion is considered a "never event." Prior reports attribute this complication to various characteristics including uncooperative patients, operator inexperience, off-hour or emergent insertion, and underutilization of ultrasound guidance. In this descriptive analysis of consecutive events, we assessed the frequency of patient, operator, and procedural factors in guidewire retention. DESIGN: Pre-specified observational analysis as part of a quality improvement study of consecutive guidewire retention events across a multihospital health system from August 2007 to October 2015. SETTING: Ten hospitals within the Cleveland Clinic Health System in Ohio, United States. PATIENTS: Consecutive all-comers who experienced guidewire retention after vascular catheter insertion. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Data were manually obtained from the electronic medical records and reviewed for potential contributing factors for guidewire retention, stratified into patient, operator, and procedural characteristics. A total of 24 events were identified. Overall, the median age was 74 years, 58% were males, and the median body mass index was 26.5 kg/m2. A total of 12 (50%) individuals were sedated during the procedure. Most incidents (10 [42%]) occurred in internal jugular venous access sites. The majority of cases (13 [54%]) were performed or supervised by an attending. Among all cases, three (12%) were performed by first-year trainees, seven (29%) by residents, three (12%) by fellows, and four (17%) by certified nurse practitioners. Overall, 16 (67%) events occurred during regular working hours (8 amto 5 pm). In total, 22 (92%) guidewires were inserted nonemergently, with two (8%) during a cardiac arrest. Ultrasound guidance was used in all but one case. CONCLUSIONS: Guidewire retention can occur even in the presence of optimal patient, operator, and procedural circumstances, highlighting the need for constant awareness of this risk. Efforts to eliminate this important complication will require attention to issues surrounding the technical performance of the procedure.
RESUMO
Background Compared with White Americans, Black Americans have a greater prevalence of cardiac events following percutaneous coronary intervention. We evaluated the association between race and neighborhood income on post-percutaneous coronary intervention cardiac events and assessed whether income modifies the effect of race on this relationship. Methods and Results Consecutive patients (n=23 822) treated with percutaneous coronary intervention from January 1, 2000, to December 31, 2016, were included. All-cause mortality and major adverse cardiac event were assessed at 3 years. Extended 10-year follow-up was performed for those residing locally (n=1285). Neighborhood income was derived using median adjusted annual gross household income reported within the patient's zip code. We compared differences in treatment and outcomes, adjusting for race, income, and their interaction. In total, 3173 (13.3%) patients self-identified as Black Americans, and 20 649 (86.7%) self-identified as White Americans. Black Americans had a worse baseline cardiac risk profile and lower neighborhood income compared with White Americans. Although risk profile improved with increasing income in White Americans, no difference was observed across incomes among Black Americans. Despite similar long-term outpatient cardiology follow-up and medication prescription, risk profiles among Black Americans remained worse. At 3 years, unadjusted all-cause mortality (18.0% versus 15.2%; P<0.001) and major adverse cardiac event (37.3% versus 34.6%; P<0.001) were greater among Black Americans and with lower income (both P<0.001); race, income, and their interaction were not significant predictors in multivariable models. At 10-year follow-up, increasing income was associated with improved outcomes only in White Americans but not Black Americans. In multivariable models for major adverse cardiac event, income (hazard ratio [HR], 0.97 [95% CI, 0.96-0.98]; P=0.005), Black race (HR, 1.77 [95% CI, 1.58-1.96]; P=0.006), and their interaction (HR, 0.98 [95% CI, 0.97-0.99]; P=0.003) were significant predictors. Similar findings were observed for cardiac death. Conclusions Early 3-year post-percutaneous coronary intervention outcomes were driven by worse risk factor profiles in both Black Americans and those with lower neighborhood income. However, late 10-year outcomes showed an independent effect of race and income, with improving outcomes with greater income limited to White Americans. These findings illustrate the importance of developing novel care strategies that address both risk factor modification and social determinants of health to mitigate disparities in cardiac outcomes.

BACKGROUND: The electrocardiography (ECG) has short-term prognostic value in coronavirus disease 2019 (COVID-19), yet its ability to predict long-term mortality is unknown. This study aimed to elucidate the predictive role of initial ECG on long-term all-cause mortality in patients diagnosed with COVID-19. METHODS: In this prospective cohort study, adults with COVID-19 who underwent ECG testing within a 17-hospital health system in Northeast Ohio and Florida between 03/2020-06/2020 were identified. An expert ECG reader analyzed all studies blinded to patient status. The associations of ECG characteristics with long-term all-cause mortality and intensive care unit (ICU) admission were assessed using Cox proportional hazards regression model and multivariable logistic regression models, respectively. Status of long-term mortality was adjudicated on 01/07/2022. RESULTS: Of 837 patients (median age 65 years, 51% female, 44% Black), 683 (81.6%) were hospitalized, 281 (33.6%) required ICU admission, 67 (8.0%) died in-hospital, and 206 (24.6%) died at final follow-up after a median (IQR) of 21 (9-103) days after ECG. Overall, 179 (20.7%) patients presented with sinus tachycardia, 12 (1.4%) with atrial flutter, and 45 (5.4%) with atrial fibrillation (AF). After multivariable adjustment, sinus tachycardia (E-value for HR=3.09, lower CI=2.2) and AF (E-value for HR=3.13, lower CI=2.03) each independently predicted all-cause mortality. At final follow-up, patients with AF had 64.5% probability of death compared with 20.5% for those with normal sinus rhythm (P<.0001). CONCLUSIONS: Sinus tachycardia and AF on initial ECG strongly predict long-term all-cause mortality in COVID-19. The ECG can serve as a powerful long-term prognostic tool in COVID-19.

Background: Physicians recommend electrophysiological (EP) procedures to patients with arrhythmic risk. This involves shared decision-making (SDM). Patients increasingly search for additional information online. Freely available online videos are an attractive source. Objective: We assessed freely available online videos for EP procedures from the perspective of SDM to determine if such videos can be shared with patients for SDM. Methods: We searched for freely available online videos related to 6 common EP procedures limited to English language and duration between 1 and 10 minutes using Google and Bing. Data collected included date and source of upload, number of hits, and duration. Videos were assessed systematically for understandability, actionability (PEMAT tool), relatability, teamwork, and mention of risk. Results: A total of 78 videos met our inclusion criteria, out of 960 video links. Overall inter-rater agreement was moderate to good. Video upload dates spanned 12 years and number of hits ranged from 87 to 594,000. The majority of videos (63%) were produced by health care systems or academic institutions. For all 78 videos the mean total PEMAT tool score was 48.6%. Thirty-five percent of videos showed a patient engaged in a conversation with the physician or a team member; 41% of videos showed other team members. The potential for complications was mentioned in 10%. Conclusion: The majority of online, freely available videos for common EP procedures lack features useful for SDM and may not be helpful for sharing with patients from that perspective. It is possible to create high-quality videos that can facilitate SDM.

BACKGROUND: The role of revascularization in patients with stable ischemic heart disease (SIHD) has been controversial, more so in the present era of drug-eluting stents. AIMS: To examine the absolute risk difference (ARD) between revascularization plus optimal medical therapy (OMT) versus OMT alone among patients with SIHD using Bayesian approach. METHODS: PubMed/MEDLINE and Cochrane citation indices were utilized to identify randomized controlled trials (RCTs) through March 31, 2020. Among trials comparing initial revascularization plus OMT with initial OMT alone, revascularization arm must have comprised >50% of patients receiving either percutaneous or surgical revascularization, and >50% of patients must have received aspirin and statin as OMT in both arms. RESULTS: Seven RCTs (12,494) were included in the final analysis. The ARD of all-cause mortality for revascularization with respect to OMT was centred at -0.002 (95% CrI: -0.01; 0.01, Tau: 0.01, 67% probability of ARD of revascularization vs. OMT < 0). The ARD for cardiac mortality was centred at -0.0025 (95%CrI: -0.01; 0.01, Tau: 0.01, 77% probability of ARD of revascularization vs. OMT < 0). The ARD for MI was -0.02 (95% CrI: -0.06; 0.00, Tau: 0.02, 97% probability of ARD for revascularization vs. OMT < 0). There was 96% probability of ARD for unstable angina with revascularization vs. OMT < 0, 4.5% probability of ARD for freedom from angina with revascularization vs. OMT < 0, and 6% probability of ARD for stroke with revascularization vs. OMT < 0. CONCLUSIONS: Bayesian analysis demonstrated minimal probability of difference in all-cause mortality and cardiac mortality in patients with SIHD who underwent revascularization compared with OMT alone. However, revascularization was associated with lower probability of MI, unstable angina, and increased freedom from angina, but a higher risk of stroke compared with OMT alone. PROSPERO: The protocol of this systematic review and meta-analysis was registered in PROSPERO [CRD42020160540].

BACKGROUND: Cardiac arrest (CA) complicating ST-elevation myocardial infarction (STEMI) is associated with a disproportionately higher risk of mortality. We described the contemporary presentation, management, and outcomes of CA patients in the era of primary percutaneous coronary intervention (PCI). METHODS: We reviewed 1,272 consecutive STEMI patients who underwent PCI between 1/1/2011-12/31/2016 and compared characteristics and outcomes between non-CA (N = 1,124) and CA patients (N = 148), defined per NCDR definitions as pulseless arrest requiring cardiopulmonary resuscitation and/or defibrillation within 24-hr of PCI. RESULTS: Male gender, cerebrovascular disease, chronic kidney disease, in-hospital STEMI, left main or left anterior descending culprit vessel, and initial TIMI 0 or 1 flow were independent predictors for CA. CA patients had longer door-to-balloon-time (106 [83,139] vs. 97 [74,121] minutes, p = 0.003) and greater incidence of cardiogenic shock (48.0% vs. 5.9%, p < 0.001), major bleeding (25.0% vs. 9.4%, p < 0.001), and 30-day mortality (16.2% vs. 4.1%, p < 0.001). Risk score for 30-day mortality based on presenting characteristics provided excellent prognostic accuracy (area under the curve = 0.902). However, over long-term follow-up of 4.5 ± 2.4 years among hospital survivors, CA did not portend any additional mortality risk (HR: 1.01, 95% CI: 0.56-1.82, p = 0.97). CONCLUSIONS: In a contemporary cohort of STEMI patients undergoing primary PCI, CA occurs in >10% of patients and is an important mechanism of mortality in patients with in-hospital STEMI. While CA is associated with adverse outcomes, it carries no additional risk of long-term mortality among survivors highlighting the need for strategies to improve the in-hospital care of STEMI patients with CA.
RESUMO
Background We aimed to understand the characteristics and outcomes of patients readmitted with a recurrent myocardial infarction (RMI) within 90 days of discharge after an acute myocardial infarction (early RMI). Methods and Results We analyzed the timing of reinfarction, etiology, and outcome for all patients admitted with an early RMI within 90 days of discharge after an acute myocardial infarction between January 1, 2010 and January 1, 2017. We identified 6626 admissions for acute myocardial infarction (index myocardial infarction) which led to 168 cases of RMI within 90 days of discharge. The mean patient age was 65.1±13.1 years, and 37% were women. The 90-day probability of readmission with an early RMI was 2.5%. Black race, medical management, higher troponin T, and shorter length of stay were independent predictors of early RMI. Medically managed group had a higher risk for early RMI compared with percutaneous coronary intervention (P=0.04) or coronary artery bypass grafting (P=0.2). Predominant mechanisms for reinfarction were stent thrombosis (17%), disease progression (12%), and unchanged coronary artery disease (11%). At 5 years, the all-cause mortality rate for patients with an early RMI was 49% (95% CI, 40%-57%) compared with 22% (95% CI, 21%-23%) for patients without an early RMI (P<0.0001). Conclusions Early RMI is a life-threatening condition with nearly 50% mortality within 5 years. Stent-related events and progression in coronary artery disease account for most early RMI. Medication compliance, aggressive risk factor management, and care transitions should be the cornerstone in preventing early RMI.

PURPOSE OF REVIEW: Pregnancy-associated myocardial infarction is a principal cause of cardiovascular disease with a steadily rising incidence of 4.98 AMI events/100,000 deliveries over the last four decades in the USA. It is also linked with significant maternal and fetal morbidity and mortality, with maternal case fatality rate ranging from 5.1 to 37%. The management of acute myocardial infarction can be challenging in pregnant patients since treatment modalities and medication use are limited by their safety during pregnancy. RECENT FINDINGS: Limited guidelines exist regarding the management of pregnancy-associated myocardial infarction. Routinely used medications in myocardial infarction including angiotensin-converting enzyme inhibitors (ACEI), angiotensin receptor blockers (ARB), and statin therapy are contraindicated during pregnancy. Aspirin use is considered safe in pregnant women, but dual antiplatelet therapy and therapeutic anticoagulation can be associated with increased risk of maternal and fetal complications, and should only be used after a comprehensive benefit-to-risk assessment. The standard approach to revascularization requires additional caution in pregnant women. Percutaneous coronary intervention is generally considered safe but can be associated with high failure rates and poor outcomes depending on the etiology. Fibrinolytic therapy may have significant sequelae in pregnant patients, and hemodynamic management during surgery is complex and adds risk during pregnancy. Understanding the risks and benefits of the different treatment modalities available and their utility depending on the underlying etiology, encompassed with a multidisciplinary team approach, is vital to improve outcomes and minimize maternal and fetal complications.

The recommended duration of dual antiplatelet therapy (DAPT) after percutaneous coronary intervention with a drug-eluting stent has changed from 1 year for all to a more personalized approach based on the patient's risks of ischemia and bleeding. The trend is toward shorter treatment in view of lower rates of late and very late stent thrombosis with newer drug-eluting stents and the risk of bleeding with DAPT. But some patients at high risk of ischemic events and low risk of bleeding may benefit from longer treatment.

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.
RESUMO
BACKGROUND: Minimizing direct patient contact among healthcare personnel is crucial for mitigating infectious risk during the coronavirus disease 2019 (COVID-19) pandemic. The use of remote cardiac telemetry as an alternative to 12lead electrocardiography (ECG) for continuous QTc monitoring may facilitate this strategy, but its application has not yet been validated or implemented. METHODS: In the validation component of this two-part prospective cohort study, a total of 65 hospitalized patients with simultaneous ECG and telemetry were identified. QTc obtained via remote telemetry as measured by 3 independent, blinded operators were compared with ECG as assessed by 2 board-certified electrophysiologists as the gold-standard. Pearson correlation coefficients were calculated to measure the strength of linear correlation between the two methods. In a separate cohort comprised of 68 COVID-19 patients treated with combined hydroxychloroquine and azithromycin, telemetry-based QTc values were compared at serial time points after medication administration using Friedman rank-sum test of repeated measures. RESULTS: Telemetry-based QTc measurements highly correlated with QTc values derived from ECG, with correlation coefficients of 0.74, 0.79, 0.85 (individual operators), and 0.84 (mean of all operators). Among the COVID-19 cohort, treatment led to a median QTc increase of 15 milliseconds between baseline and following the 9th dose (p = 0.002), with 8 (12%) patients exhibiting an increase in QTc ≥ 60 milliseconds and 4 (6%) developing QTc ≥ 500 milliseconds. CONCLUSIONS: Cardiac telemetry is a validated clinical tool for QTc monitoring that may serve an expanding role during the COVID-19 pandemic strengthened by its remote and continuous monitoring capability and ubiquitous presence throughout hospitals.

Despite decades of improvement in the quality and outcomes of cardiovascular care, significant gaps remain. Existing quality improvement strategies are often limited in scope to specific clinical conditions and episodic care. Health services and outcomes research is essential to inform gaps in care but rarely results in the development and implementation of care delivery solutions. Although individual health systems are engaged in projects to improve the quality of care delivery, these efforts often lack a robust study design or implementation evaluation that can inform generalizability and further dissemination. Aligning the work of health care systems and health services and outcomes researchers could serve as a strategy to overcome persisting gaps in cardiovascular quality and outcomes. We describe the inception of the Cardiovascular Quality Improvement and Care Innovation Consortium that seeks to rapidly improve cardiovascular care by (1) developing, implementing, and evaluating multicenter quality improvement projects using innovative care designs; (2) serving as a resource for quality improvement and care innovation partners; and (3) establishing a presence within existing quality improvement and care innovation structures. Success of the collaborative will be defined by projects that result in changes to care delivery with demonstrable impacts on the quality and outcomes of care across multiple health systems. Furthermore, insights gained from implementation of these projects across sites in Cardiovascular Quality Improvement and Care Innovation Consortium will inform and promote broad dissemination for greater impact.

Aims: To determine whether a comprehensive ST-elevation myocardial infarction (STEMI) protocol is associated with reduced sex disparities over 5 years. Methods and results: This was an observational cohort study of 1833 consecutive STEMI patients treated with percutaneous coronary intervention (PCI) before (1 January 2011-14 July 2014, control group) and after (15 July 2014-15 July 2019, protocol group) implementation of a protocol for early guideline-directed medical therapy (GDMT), rapid door to balloon time (D2BT), and use of trans-radial PCI. In the control group, females had less GDMT (77.1% vs. 68.1%, P = 0.03), similarly low trans-radial PCI (19.0% vs. 17.6%, P = 0.73), and longer D2BT [104 min (79, 133) vs. 112 min (85, 147), P = 0.02] corresponding to higher in-hospital mortality [4.5% vs. 10.3%, odds ratio (OR) 2.44 (1.34-4.46), P = 0.004], major adverse cardiac and cerebrovascular events [MACCE, 9.8% vs. 16.3%, OR 1.79 (1.14-2.84), P = 0.01], and net adverse clinical events [NACE, 16.1% vs. 28.3%, OR 2.06 (1.42-2.99), P < 0.001]. In the protocol group, no significant sex differences were observed in GDMT (87.2% vs. 86.4%, P = 0.81) or D2BT [85 min (64-106) vs. 89 min (65-111), P = 0.06], but trans-radial PCI was used less in females (77.6% vs. 71.2%, P = 0.03). In-hospital mortality [2.5% vs. 4.4%, OR 1.78 (0.91-3.51), P = 0.09] and MACCE [9.0% vs. 11.1%, OR 1.27 (0.83-1.92), P = 0.26] were similar between sexes, but higher NACE in females approached significance [14.8% vs. 19.4%, OR 1.38 (0.99-1.92), P = 0.05] due to higher bleeding risk [7.2% vs. 11.1%, OR 1.60 (1.04-2.46), P = 0.03]. Conclusions: A comprehensive STEMI protocol was associated with sustained reductions for in-hospital ischaemic outcomes over 5 years, but higher bleeding rates in females persisted.
