Transcatheter aortic valve replacement (TAVR) is the treatment of choice for patients with severe aortic stenosis across the spectrum of surgical risk. About one-third of 30-day readmissions following TAVR are related to heart failure (HF). Hence, we aim to develop an easy-to-use clinical predictive model to identify patients at risk for HF readmission. We used data from the National Readmission Database (2015-2018) utilizing ICD-10 codes to identify TAVR procedures. Readmission was defined as the first unplanned HF readmission within 30-day of discharge. A machine learning framework was used to develop a 30-day TAVR-HF readmission score. The receiver operator characteristic curve was used to evaluate the predictive power of the model. A total of 92,363 cases of TAVR were included in the analysis. Of the included patients, 3299 (3.6%) were readmitted within 30 days of discharge with HF. Individuals who got readmitted, vs those without readmission, had more emergent admissions during index procedure (33.4% vs 19.8%), electrolyte abnormalities (38% vs 16.7%), chronic kidney disease (34.8% vs 21.2%), and atrial fibrillation (60.1% vs 40.7%). Candidate variables were ranked by importance using a parsimony plot. A total of 7 variables were selected based on predictive ability as well as clinical relevance: HF with reduced ejection fraction (25 points), HF preserved EF (20 points), electrolyte abnormalities (17 points), atrial fibrillation (12 points), Charlson comorbidity index (<6 = 0, 6-8 = 9, 9-10 = 13, >10 = 14 points), chronic kidney disease (7 points), and emergent index admission (5 points). On performance evaluation using the testing dataset, an area under the curve of 0.761 (95% CI 0.744-0.778) was achieved. Thirty-day TAVR-HF readmission score is an easy-to-use risk prediction tool. The score can be incorporated into electronic health record systems to identify at-risk individuals for readmissions with HF following TAVR. However, further external validation studies are needed., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023.

Transcatheter aortic valve implantation (TAVI) is accepted as an alternative to surgery, but data on combined percutaneous coronary interventions (PCI) and TAVI during the same in-hospital stay are still lacking. Using the national inpatient sample (NIS) database, we identified all TAVI encounters and compared in-hospital outcomes of patients who had TAVI only to patients who had TAVI and PCI. We used multivariable logistic regression analysis to calculate the adjusted odds ratio (aOR). Of 291,810 patient encounters with TAVI, 13,114 (4.5%) had combined PCI during the same index admission. The average age was 79.61 ± 8.61 years in the TAVI-only vs 80.25 ± 8.73 years in the combined TAVI-PCI group. Combined TAVI and PCI was associated with higher in-hospital mortality (4.5% vs 1.8%, aOR: 2.3), stroke (4.7% vs 2.9%, aOR: 1.4), net adverse events (NAE) (20.2% vs 5.7%, aOR: 3.6), major bleeding (40.1% vs 24.3%, aOR: 1.8), vascular complications (10.6% vs 2.5%, aOR: 3.9), acute kidney injury (AKI) (23.3% vs 11.7%, aOR: 2.1), hemodialysis (HD) (4.2% vs 2.4%, aOR: 1.4), postoperative cardiogenic shock (1.2% vs 0.4%, aOR: 2.8), need for mechanical circulatory support (6.9% vs 1%, aOR: 7); p-value < 0.001 for all. The utilization of permanent pacemakers was similar between the groups (9.8% vs 9.2%, aOR: 1; p = 0.6). Combining TAVI and PCI during the same index admission is associated with worse outcomes. The decision to do PCI for patients undergoing TAVI should be individualized and tailored based on the patient's clinical conditions., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Inc.

Transcatheter aortic valve implantation (TAVI) has increasingly been utilized in patients with aortic insufficiency (AI) with insufficient data on its safety. The Nationwide Readmissions Database (NRD) was queried to identify patients undergoing TAVI for AI. Net clinical events (composite of in-hospital mortality, stroke, major bleeding) and procedural complications were assessed using a propensity-score matched (PSM) analysis to calculate adjusted odds ratios (OR). A total of 185,703 (AI 3873, aortic stenosis [AS] 181,830) patients were included in the analysis. Due to a significant difference in the baseline characteristics, a matched sample of 7929 patients (AI 3873, AS 4056) was selected. At index admission, the adjusted odds of in-hospital NACE (aOR 2.0, 95% CI 1.59-2.51), mortality (aOR 3.06, 95% CI 2.38-5.47), major bleeding (aOR 1.53, 95% CI 1.13-2.06) and valvular complications (aOR 9.48, 95% CI 6.73-13.38) were significantly higher in patients undergoing TAVI for AI compared with those undergoing TAVI for AS. However, there was no significant difference in the incidence of NACE, mortality, stroke, major bleeding, and need for permanent pacemaker implantation at 30- and 180-days follow-up. TAVI in AI was associated with a higher risk of periprocedural NACE, mortality, and major bleeding. The risk of these complications attenuated at 30- and 180-day readmission., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Inc.

Transcatheter edge-to-edge repair (TEER) has emerged as a widely accepted procedure for tricuspid regurgitation (TR) as gauged by echocardiographic parameters and clinical outcomes. Our study aims to assess TR severity and other echocardiographic outcomes in patients undergoing TEER with TriClip, MitraClip, and PASCAL devices. A literature search of 5 databases was performed until 1st June 2023. Randomized controlled trials (RCTs) or observational studies with moderate to severe (grade III-V) TR patients undergoing isolated TEER were considered eligible. Echocardiographic, and quality of life determining outcomes such as improvement in TR severity grade ≥3, New York Heart Association (NYHA) class ≥3, procedural success, 6-minute walking distance (6MWD), and adverse outcomes were analyzed. Grade assessment was performed and studies were assessed for risk of bias and publication bias. We included 15 studies (14 observational and 1 RCT) in our paper. Analysis revealed a substantial reduction in TR volume (P < 0.00001), TR grading (P < 0.00001), tricuspid annular diameter (P < 0.00001), proximal isovelocity surface area radius (P < 0.00001), effective regurgitant orifice area (P < 0.00001), and improvement in NYHA class (P < 0.00001) at 30 days from baseline, postprocedurally. A significant increase in 6MWD at 1 year (P = 0.001) was also recorded. No significant differences in left ventricular ejection fraction (P = 0.87), fractional area change (P = 0.37), or tricuspid annular plane systolic excursion (P = 0.76) were observed. TEER procedural success was 97%. TEER produced a significant reduction in TR grade and volume, NYHA class, 6MWD, and showed prominent procedural success. Large scale RCTs comparing the TEER devices are needed to strengthen the present findings., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Inc.

Hypertension (HTN) is characterized by an elevated arterial blood pressure with no apparent symptom while proving to be a crucial risk factor for the other underlying disorders such as cardiac failure, atrial fibrillation, stroke and various others, steering to recurrent premature deaths worldwide if left untreated. There are innumerate factors responsible for causing HTN such as age factor, obesity, inheritance, physical inactivity, stress, and unhealthy diet whereas some therapeutics and pharmaceuticals may too trigger this condition notably caffeine. As caffeine is amongst the most widely consumed drinks worldwide and hence an ordeal to cease its use, accordingly this review article in-sighted to raise cognizance specifically towards the action of caffeine affiliated with HTN. Therefore, this review is focused on the risk factors and preventive measures associated with HTN, especially the role of caffeine in inducing HTN as to create social awareness regarding how the excessive habituated caffeine consumption may aggravate this condition., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Inc.

In patient undergoing transcatheter aortic valve implantation (TAVI), stroke remains a potentially devastating complication associated with significant morbidity, and mortality. To reduce the risk of stroke, cerebral protection devices (CPD) were developed to prevent debris from embolizing to the brain during TAVI. We performed a systematic review and meta-analysis to determine the safety and efficacy of CPD in TAVI. The MEDLINE (PubMed, Ovid) and Cochrane databases were queried with various combinations of medical subject headings to identify relevant articles. Statistical analysis was performed using a random-effects model to calculate unadjusted odds ratio (OR), including subgroup analyses based on follow-up duration, study design, and type of CPD. Using a pooled analysis, CPD was associated with a significant reduction in major adverse cardiovascular events MACE (OR 0.75, 95% CI 0.70-0.81, P < 0.01), mortality (OR 0.65, 95% CI 0.58-0.74, P < 0.01) and stroke (OR 0.84, 95% CI 0.76-0.93, P < 0.01) in patients undergoing TAVI. Similarly, on MRI volume per lesion were lower for patients with CPD use. No significant difference was observed in acute kidney injury (OR 0.75, 95% CI 0.42-1.37, P = 0.68), bleeding (OR 0.92, 95% CI 0.71-1.20, P = 0.55) or vascular complications (OR 0.90, 95% CI 0.62-1.31, P = 0.6) for patients undergoing TAVI with CPD. In conclusion, CPD device use in TAVI is associated with a reduction of MACE, mortality, and stroke compared with patients undergoing TAVI without CPD. However, the significant reduction in mortality is driven mainly by observational studies., (Copyright © 2022 Elsevier Inc. All rights reserved.)

Data on the feasibility of same-day discharge (SDD) following percutaneous left atrial appendage closure (LAAC) remain limited. We analyzed the US Nationwide Readmission Database from quarter four of 2015 to 2019 to study the safety and feasibility of SDD after LAAC. After excluding non-elective cases and in-hospital deaths, a total of 54,880 cases of LAAC were performed during the study period. Following LAAC, 2% (n=1077) of patients underwent SDD, 88% (n=48,428) underwent next-day discharge (NDD), 5.2% (n=2881) were discharged on the second day (ScD), and 4.5% of patients (n = 2494) were discharged 3 or more days after LAAC. There was no difference in 30-day readmission rates between SDD and NDD (7.3% [n=79] vs 7.4% [n=3585], P=0.94). The hospitalization costs were significantly lower for SDD compared with NDD ($22,963 vs $27,079, P≤0.01). SDD discharge following percutaneous LAAC appears to be safe and is associated with lower hospitalization costs. Further prospective studies are needed to determine the safety and feasibility of SDD with percutaneous LAAC., (Copyright © 2023 Elsevier Inc. All rights reserved.)

Due to shared risk factors, many patients with severe aortic stenosis (AS) also have concomitant peripheral arterial disease (PAD). The readmission rates and long term clinical outcomes of these patients following transcatheter aortic valve implantation (TAVI) in a large sample has not been well defined. The National Readmissions Database (NRD) (2015-2019) was used to identify patients undergoing TAVI. TAVI in patients with PAD was compared with those without PAD using a propensity score matched (PSM) analysis to obtain adjusted odds ratios (aOR) with 95% confidence intervals (CI) of net adverse clinical events (NACE), and its components. A total of 189,216 patients were identified, of which 14,925 patients (7386 with PAD, 7539 without PAD) were selected for adjusted analysis. Using PSM, patients with PAD undergoing TAVI had significantly higher in-hospital adjusted odds of NACE (aOR 1.60, 95% CI 1.36-1.88), and mortality (aOR 4.10, 95% CI 2.88-5.83). However, rates of other in-hospital peri procedural complications (stroke, major bleeding, paravalvular leak, cardiogenic shock) were not significantly different. There was no significant difference in the incidence of NACE, mortality, or other complications between the 2 groups at 30- and 180 days follow-up. Patients with PAD undergoing TAVI have an increased risk of mortality and NACE during the periprocedural period. However, following discharge, there was no statistically significant difference in 30 days and 6 month outcomes of TAVI in this population compared to those without significant PAD., (Copyright © 2023 Elsevier Inc.

The merits of conservative management vs early intervention in patients with asymptomatic severe aortic stenosis remains unknown. Digital databases (MEDLINE, Google Scholar, and Embase) were searched for all relevant studies from inception through September 2022. Studies comparing conservative management with early intervention were compared using a random-effects model to calculate risk ratios (RRs) with 95% confidence interval (CI). A total of 12 studies comprising 3624 asymptomatic aortic stenosis patients (1747 receiving surgery, and 1877 receiving conservative treatment) were included in the analysis. The average follow-up time was 4.45 (IQR 3.5-5) years. Early intervention was associated with a significantly reduced risk of cardiac (RR 0.42, 95% CI 0.25-0.72; P = 0.001; I 2  = 54%), non-cardiac (RR 0.46, 95% CI 0.32-0.68; P < 0.0001; I 2  = 0%), all-cause mortality (RR 0.40, 95% CI 0.32-0.51; P < 0.00001; I 2  = 58%), heart failure hospitalization (RR 0.21, 95% CI 0.13-0.36; P < 0.00001; I 2  = 0%), sudden cardiac death (RR 0.29, 95% CI 0.12-0.66; P = 0.004, I 2  = 24%), and MACE (RR 0.46, 95% CI; 0.28-0.75; P = 0.002; I 2  = 68%), compared with conservative management. There was no significant difference in the 30-day mortality (RR 0.63, 95% CI 0.19-2.04; P = 0.44; I 2  = 28%), myocardial infarction (RR 0.44, 95% CI 0.19-1.06; P = 0.07, I 2 =0%), and 90-day mortality (RR 0.68, 95% CI 0.20-2.37; P = 0.55; I 2  = 61%) between the 2 groups. This meta-analysis shows statistically significant reductions in the risk for all-cause mortality, cardiac specific mortality, non-cardiac mortality, heart failure hospitalization, MACE, and sudden cardiac death among asymptomatic aortic stenosis patients who underwent early intervention as opposed to conservative management., (Copyright © 2022 Elsevier Inc.

The Coronavirus Disease-2019 (COVID-19) pandemic placed an enormous strain on the healthcare system. Data on the impact of COVID-19 on the utilization and outcomes of structural heart disease interventions in the United States are scarce. The National Inpatient Sample from 2016 to 2020 was queried to identify adult admissions for transcatheter aortic valve replacement (TAVR), left atrial appendage occlusion (LAAO), and transcatheter end-to-end repair (TEER). The primary outcome was temporal trends of procedure utilization rate per 100,000 admissions over quarters from 2016 to 2020. The secondary outcomes were adjusted rates of in-hospital mortality, major complications, and length of stay (LOS). Among 434,630 weighted admissions (TAVR: 305,550; LAAO: 89,300; TEER: 40,160), 95,010 admissions (22%) were during the COVID-19 era. There was a decline during the second quarter of 2020 followed by an increase to the pre pandemic levels (TAVR: 220 to 253, LAAO: 57 to 109, and TEER: 31 to 36 per 100,000 admissions, Ptrend<0.001). There were no differences in the mortality or major complication rates. Median LOS has decreased in TAVR (4 days-1 day) and in TEER (3 days-1 day) but remained stable in LAAO (1 day). This nationwide analysis showed that structural heart disease interventions decreased during the early waves of COVID-19 pandemic. There was a significant reduction in hospital LOS without differences in in-hospital mortality or complication rates during the pandemic. These data suggest that hospitals adapted to the unprecedent challenges during the pandemic to provide advanced cardiac care to patients., (Copyright © 2022 Elsevier Inc. All rights reserved.)

The impact of intravascular imaging guidance [intravascular ultrasound (IVUS)/optical coherence tomography (OCT)] on clinical outcomes in patients undergoing orbital atherectomy (OA) and percutaneous intervention (PCI) are not well characterized. The Nationwide Readmissions Database (NRD) from 2015 to 2019 was used to select all cases of OA. The adjusted odds ratios (aOR) of in-hospital, 30-day, and 180-day hospitalization outcomes between patients who underwent PCI with OA vs without intravascular imaging were calculated using a propensity-matched analysis. A total of 15,681 patients undergoing PCI after OA (12,649 with no-imaging, 3032 with imaging) were identified. Due to a significant difference in the baseline characteristics, a matched sample of 3008 in the no-imaging group and 3032 in the imaging group was selected. On adjusted analysis, the odds of all-cause in-hospital mortality (aOR 0.68, 95% CI 0.54-0.86) were significantly lower in patients undergoing IVUS/OCT guided OA and PCI compared with those having PCI without imaging. There was no difference in the rate of in-hospital stroke (aOR 0.86, 95% CI 0.51-1.45) and major bleeding (aOR 0.87, 95% CI 0.65-1.16) between the two groups. There was no significant difference in the 30- and 180-day odds of readmission, major bleeding, coronary dissection, pericardial effusion, and AKI between the two groups. IVUS and OCT use during PCI with OA for patients with calcified coronary artery disease appear to be associated with reduced in-hospital mortality at index admission. Prospective trials are necessary to determine the long-term benefits of imaging with PCI., (Copyright © 2022 Elsevier Inc. All rights reserved.)

Left atrial appendage occlusion using the Watchman device has emerged as an alternative treatment strategy for preventing strokes in patients with atrial fibrillation. However, there is no data on its safety and clinical outcomes in prior renal or liver transplant recipients. We included a total of 61,995 patients from the National Inpatient Sample (NIS, in-hospital outcomes) and 55,048 patients from the National Readmission Database (NRD, 30-day outcomes) who underwent percutaneous left atrial appendage occlusion (LAAO). From this group, 0.65% (n=405) and 0.62% (n=339) were renal and liver transplant recipients in NIS and NRD respectively. Transplant recipients were younger compared with non-transplant recipients (mean age 69 vs 77 years, P=<0.01). There was little difference in terms of in-hospital mortality (0% vs 0.2%, P=0.43), major complications (6.2% vs 5.6%, P=0.61), cardiovascular complications (2.5% vs 2.8%, P=0.73), neurological complications (1.2% vs 0.7%, P=0.21) or bleeding complications (1.2% vs 0.7%, P=0.99) between transplant vs. non-transplant patients. Based on the NRD database, 30-day readmission rate was not meaningfully different for transplant recipients undergoing LAAO (9.44%) when compared to non-transplant patients (8.12%, [log-rank, P=0.56]). There was no difference between 30-day major or cardiovascular complications, however vascular complication rates were significantly higher for transplant recipients (OR 2.56, 95% CI [(1.66-3.47]). Our study findings suggest that LAAO may be safe for patients with a prior renal or liver transplant in terms of major complications, cardiovascular complications, and all-cause readmission rates. However vascular complications may be higher in transplant recipients. Further large-scale studies are needed to confirm these findings., (Copyright © 2022 Elsevier Inc. All rights reserved.)

Newer generation transcatheter heart valves (THV) are presumed to yield better clinical efficacy and postprocedural complication profile as compared to transcatheter aortic valve replacement (TAVR) using older generation THVs. The real impact of newer generation valves on TAVR outcomes is not well known. Studies comparing older and newer generation THVs were identified from online databases including PubMed, EMBASE, Cochrane, and ClinicalTrials.gov from inception until August 2020. The primary outcome of the study was to compare mortality. Secondary outcomes included cerebrovascular events, myocardial infarction, major vascular complications, major bleeding, acute kidney injury, paravalvular leak, and post-procedural pacemaker implantation. Statistical analysis was performed using the Mantel-Haenszel random effect model with an odds ratio (OR), 95% confidence interval (CI), and p-value significance ≤0.05. A total of 14 studies were included with a combined patient population of 5697 patients (older generation n=1996; newer generation n=3701). Newer generation valves showed statistically significant results favoring lower major vascular complications (OR=2.05; 95% CI, 1.33-3.18; P = 0.00), major bleeding (OR=1.99; 95% CI, 1.35-2.93; P = 0.00), acute kidney injury (OR=1.71; 95% CI, 1.13-2.59; P = 0.01), paravalvular leak (OR=2.41; 95% CI, 1.11-5.28; P = 0.03) and mortality (OR=1.50; 95% CI, 1.10-2.06; P = 0.01) as compared to older generation valves. Cerebrovascular events, myocardial infarction, and pacemaker placement rates were found to be similar between older and newer generation valves. TAVR outcomes using newer generation valves are superior to those of older generation valves in terms of major vascular complications, acute kidney injury, paravalvular leak, and mortality., (Copyright © 2022 Elsevier Inc.

Transcutaneous aortic valve implantation (TAVI) has transformed the management of aortic stenosis (AS) and is increasingly being used for patients with symptomatic, severe aortic stenosis who are ineligible or at high risk for conventional cardiac surgery. PUBMED, Google Scholar, and SCOPUS databases were searched to identify studies reporting heart failure hospitalization after TAVI. Major factors evaluated for HF hospitalization were age, comorbidities such as hypertension, atrial fibrillation (AF), chronic pulmonary disease including COPD, chronic kidney disease, baseline LVEF before the procedure, NYHA symptom class, and society of thoracic surgeons (STS) score. Hazard ratio (HR) with a 95% confidence interval were computed using random-effects models. A total of eight studies were included comprising 77,745 patients who underwent TAVI for severe aortic stenosis. The presence of diabetes mellitus (HR: 1.39, 95% CI [1.17, 1.66], chronic kidney disease (CKD) (HR: 1.39, 95% CI [1.31, 1.48], atrial fibrillation (HR: 1.69, 95% CI [1.42, 2.01], chronic pulmonary disease (HR: 1.33, 95% CI [1.12, 1.58], and a high STS score (HR: 1.07, 95% CI [1.03, 1.11] were positive predictors of 1-year HF hospitalization after TAVI. Patients with diabetes mellitus, AF, CKD, chronic pulmonary disease, and a high STS score are at an increased risk of heart failure hospitalization at 1-year of TAVI, whereas increasing age, hypertension, LVEF <50%, and NYHA class III/IV symptoms did not predict HF hospitalization. Careful follow-up after TAVI in high-risk patients, with closer surveillance for HF particularly, is key to preventing HF hospitalizations and death., (Copyright © 2022. Published by Elsevier Inc.)

Contemporary data on stroke predictors and outcomes in patients undergoing transcatheter aortic valve implantation (TAVI) remains limited. We analyzed National Inpatient Sample data from the year 2011 to 2018. A total of 215,938 patients underwent TAVI. Of the patients who underwent TAVI, 4579 (2.2%) suffered from stroke and 211359 (97.8%) did not have a stroke. Adjusted mortality was higher in patients who had a stroke (10.9%) as compared to patients who did not have a stroke (3.1%). Lower percentage of patients were discharged home who developed a stroke compared to patients without a stroke (10.2% vs 52.3%). Multivariate logistic regression analysis showed that at baseline, age, female sex, atrial fibrillation, chronic kidney disease and peripheral vascular disease were significant predictors of stroke. Median Cost of care ($63367 vs $48070) and length of stay (8 vs 4 days) were considerably higher for patients with stroke when compared to the comparison group (P < 0.01 for all). In conclusion we report that stroke is associated with increased mortality, morbidity, and resource utilization in patients undergoing TAVI. Baseline characteristics like age, gender, atrial fibrillation, chronic kidney disease and peripheral vascular disease are significant predictors of this adverse event., (Copyright © 2021 Elsevier Inc.

Atrial fibrillation (AF) is the most prevalent arrhythmia in the United States. However, studies evaluating the impact of iron deficiency anemia on AF outcomes are limited. Therefore, we aimed to evaluate the association of iron deficiency anemia (IDA) on clinical outcomes in patients hospitalized with AF. A retrospective analysis of adult hospital discharges from the National Inpatient Sample (NIS) between 2004 and 2018 was conducted. Multivariable logistic regression was used to assess the association of IDA and other clinical outcomes ie inpatient mortality, acute myocardial infarction, cardiogenic shock, acute kidney injury, vasopressors use, length of stay, and other resource utilization. These models were adjusted for patient and hospital-level characteristics. A total of 5,975,241 weighted primary AF hospitalizations were identified. Out of these, 152,059 (2.5%) had diagnosis of IDA. After adjustment of variables, admissions with IDA were associated with higher rates of acute myocardial infarction (adjusted odds ratio [aOR] = 1.10, 95% CI 1.01-1.19 P = 0.026), use of vasopressors (aOR = 1.30, CI 1.27-1.32, P <0.001), invasive mechanical ventilation (aOR = 1.26, CI 1.14-1.40 P <0.001) and acute kidney injury (aOR = 1.72, CI 1.66-1.79 P <0.001). There was no significant difference in all-cause mortality (aOR = 0.97, CI 0.87-1.07, P = 0.513), cardiogenic shock, in-hospital cardiac arrest or use of mechanical circulatory support. Adjusted mortality in patients with AF and IDA decreased from 1.09% to 0.54% from 2004 to2018 (P -trend < 0.001). Among hospitalized patients with AF, our study did not show any difference in all-cause mortality between those with and without IDA., (Copyright © 2021 Elsevier Inc. All rights reserved.)
