Underutilization of Drug-Eluting Stents in Infrapopliteal Intervention for Chronic Limb-Threatening Ischemia.

PURPOSE: Multiple randomized clinical trials have shown superiority of drug-eluting stents (DES) over bare-metal stents (BMS) for infrapopliteal disease. However, real-world data on DES utilization and outcomes in infrapopliteal chronic limb-threatening ischemia (CLTI) patients are unknown. MATERIALS AND METHODS: We utilized the Nationwide Readmission Database (NRD) from 2016 to 2017 to extract patients undergoing infrapopliteal intervention with stents (BMS and DES) for CLTI using appropriate ICD-10 codes. Multilevel logistic regression with hospital ID as random effect was used to assess DES utilization. Primary outcome was the composite of target limb major amputation (TLmajA) and target limb revascularization (TLR). Multivariate Cox-proportional hazard regression was used to adjust for confounders. RESULTS: Our study included a total of 1817 patients. Of these patients, 1056 patients (58.1%) received DES; DES utilization was stable (relative change: +2.5%, p-trend: 0.867) between 2016 and 2017 and was higher in teaching hospitals (adjusted odds ratio [aOR] = 1.28, 95% CI = 1.03-1.61, p=0.029] and medium (aOR = 3.13, 95% CI = 2.17-4.55, p≤0.001) and large (aOR = 1.56, 95% CI = 1.14-2.17, p=0.005) bed-sized hospitals. Inter-class correlation was 0.44 suggesting ~44% variation in DES utilization between any 2 random hospitals; DES was associated with lower rate of the primary composite outcome (aHR = 0.75, 95% CI = 0.62-0.92, p=0.004) compared with BMS. CONCLUSION: In patients undergoing infrapopliteal intervention for CLTI, DES demonstrated significant underutilization despite supportive evidence of their superiority compared with BMS; DES was associated with improvement in the primary composite outcome compared with BMS.

One-year outcomes of catheter ablation for atrial fibrillation in young patients.

BACKGROUND: Atrial fibrillation (AF) is relatively less frequent in younger patients (age < 50). Recently, studies have suggested that early restoration of sinus rhythm may lead to improved outcomes compared with rate control, however the efficacy of catheter ablation for AF in young is scarce. METHODS: We included all hospitalized patients between 18 and 50 years with a diagnosis of AF from the Nationwide Readmission Database 2016-2017 from the Healthcare Cost and Utilization Project. Demographic and comorbidity data were collected and analyzed. Outcomes assessed included one-year AF readmission rates, all-cause readmission, ischemic stroke, and all-cause mortality. Subgroup analyses were performed for all demographic and comorbidity variables. RESULTS: Overall, 52,598 patients (medium age 44, interquartile range 38-48, female 25.7%) were included in the study, including 2,146 (4.0%) who underwent catheter ablation for AF. Patients who underwent catheter ablation had a significantly lower rate of readmission for AF or any cause at one year (adjusted hazard ratios (HR) of 0.52 [95% confidence interval (CI): 0.43-0.63] and HR of 0.81 [95% CI: 0.72-0.89], respectively). There was no difference in 1-year readmission for stroke or all-cause mortality between the two groups. Subgroup analyses showed a consistent reduction in the risk of AF readmission among major demographic and comorbidity subgroups. CONCLUSION: Catheter ablation in young patients with AF was associated with a reduction in 1-year AF related and all-cause readmissions. These data merit further prospective investigation for validation, through dedicated registries and multicenter collaborations to include young AF from diverse population.

Outcomes Associated With Early vs. Delayed Invasive Strategy in NSTEMI Complicated by High Degree AV Block: A Nationwide Analysis.

Background: High degree atrioventricular block (HDAVB) is an uncommon complication of non-ST-segment elevation myocardial infarction (NSTEMI) that frequently necessitates pacemaker implantation. This contemporary analysis compares need for pacemaker implantation based on the timing of intervention in acute NSTEMI complicated by HDAVB.Methods: We used 2016-2017 National Inpatient Sample database to identify admissions with NSTEMI and HDAVB. Time to coronary intervention from initial admission was used to segregate the admissions into two groups: early invasive strategy (EIS) (<24 hours) and delayed invasive strategy (DIS) (>24 hours). Multivariable linear and logistic regression analysis was performed to compare in-hospital outcomes among the two groups.Results: Out of 949,984 NSTEMI related admissions, coexistent HDAVB was present in 0.7% (n=6725) patients. Amongst those, 55.61% (n=3740) hospitalizations included invasive intervention (EIS=1320, DIS=2420). Patients treated with EIS were younger (69.95 years vs. 72.38 years, P<0.05) and had concomitant cardiogenic shock. Contrarily, prevalence of chronic kidney disease, heart failure, and pulmonary hypertension was higher in DIS group. EIS was associated with lower length of stay and total hospitalization cost. In-hospital mortality and pacemaker implantation rates were not significantly different between patients in the EIS and DIS groups.Conclusion: HDAVB is a rare complication of NSTEMI and often associated with right coronary artery disease. The timing of revascularization does not appear to influence the rate of pacemaker placement in NSTEMI complicated by HDAVB. Further studies are needed to assess if early invasive strategy can benefit all patients with NSTEMI and HDAVB.

Inpatient cardiovascular outcomes in patients with cancer affected by viral influenza infection.

BACKGROUND: Influenza disproportionately affects individuals with underlying comorbidities. Long-term follow-up studies have shown that patients with cancer with influenza have higher mortality. However, very little is known about the in-hospital mortality and cardiovascular outcomes of influenza infection in cancer hospitalisations. METHODS: We compared the in-hospital mortality and cardiovascular outcomes in patients with cancer with and without influenza by screening the National Inpatient Sample from 2015 to 2017. A total of 9 443 421 hospitalisations with any cancer were identified, out of which 14 634 had influenza while 9 252 007 did not. A two-level hierarchical multivariate logistic regression analysis adjusted for age, sex, race, hospital type and relevant comorbidities was performed. RESULTS: The group with cancer and influenza had higher in-hospital mortality (OR 1.08; 95% CI 1.003 to 1.16; p=0.04), acute coronary syndromes (OR 1.74; 95% CI 1.57 to 1.93; p<0.0001), atrial fibrillation (OR 1.24; 95% CI 1.18 to 1.29; p<0.0001) and acute heart failure (OR 1.41; 95% CI 1.32 to 1.51; p<0.0001). CONCLUSION: Patients with cancer affected by influenza have higher in-hospital mortality and a higher prevalence of acute coronary syndrome, atrial fibrillation and acute heart failure.

Impact of Chronic Kidney Disease on In-Hospital Outcomes of Hospitalizations With Acute Limb Ischemia Undergoing Endovascular Therapy.

PURPOSE: Studies on outcomes related to endovascular treatment (EVT) in advanced stages of chronic kidney disease (CKD) and end-stage renal disease (ESRD) among hospitalizations with acute limb ischemia (ALI) are limited. METHODS: The Nationwide Inpatient Sample was quarried from October 2015 to December 2017 to identify the hospitalizations with ALI and undergoing EVT. The study population was subdivided into 3 groups based on their CKD stages: group 1 (No CKD, stage I, stage II), group 2 (CKD stage III, stage IV), and group 3 (CKD stage V and ESRD). The primary outcome was all-cause in-hospital mortality. RESULTS: A total of 51 995 hospitalizations with ALI undergoing EVT were identified. The in-hospital mortality was significantly higher in group 2 (OR = 1.17; 95% CI 1.04 - 1.32, p=0.009) and group 3 (OR = 3.18; 95% CI 2.74-3.69, p<0.0001) compared with group 1. Odds of minor amputation, vascular complication, atherectomy, and blood transfusion were higher among groups 2 and 3 compared with group 1. Group 2 had higher odds of access site hemorrhage compared with groups 1 and 3, whereas group 3 had higher odds of major amputation, postprocedural infection, and postoperative hemorrhage compared with groups 1 and 2. Besides, groups 2 and 3 had lower odds of discharge to home compared with group 1. Finally, the length of hospital stay and cost of care was significantly higher with the advancing CKD stages. CONCLUSION: Advanced CKD stages and ESRD are associated with higher mortality, worse in-hospital outcomes and higher resource utilization among ALI hospitalizations undergoing EVT. CLINICAL IMPACT: Current guidelines are not clear for the optimum first line treatment of acute limb ischemia, especially in patients with advanced kidney disease as compared to normal/mild kidney disease patients. We found that advanced kidney disease is a significant risk factor for worse in-hospital morbidity and mortality. Furthermore, patients with acute limb ischemia and advanced kidney disease is associated with significantly higher resource utilization as compared to patients with normal/mild kidney disease. This study suggests shared decision making between treating physician and patients when considering endovascular therapy for the treatment of acute limb ischemia in patients with advanced kidney disease.

CONCLUSION: Patients with cancer affected by influenza have higher in-hospital mortality and a higher prevalence of acute coronary syndrome, atrial fibrillation and acute heart failure.

Short term outcomes of rotational atherectomy versus orbital atherectomy in patients undergoing complex percutaneous coronary intervention: a systematic review and meta-analysis.

OBJECTIVE: Coronary artery calcification (CAC) is one of the paramount hurdles for percutaneous coronary intervention (PCI) since it impedes stent delivery and complete expansion. This study intended to evaluate the short-term clinical and procedural outcomes comparing rotational atherectomy (RA) and orbital atherectomy (OA) in patients with heavily calcified coronary lesions undergoing PCI. Design: This systematic review and meta-analysis included all head-to-head published comparisons of coronary RA versus OA. Procedural endpoints and post-procedural clinical outcomes (30 days/in-hospital), were compared. RevMan 5.3 software was used for data analysis. Results: Seven retrospective observational investigations with a total of 4623 patients, including 3203 patients in the RA group and 1420 patients in the OA group, were incorporated. Compared with OA, the RA group was associated with a higher incidence of myocardial infarction at short-term follow-up (OR: 1.56, 95% CI: 1.07-2.29, p = .02, I2 = 0%). No difference was noted among other short-term post-procedural clinical outcomes including all-cause mortality, target vessel revascularization, or major adverse cardiac events. Among procedural complications, RA was associated with reduced coronary artery dissection and arterial perforation. Increased fluoroscopy time was observed in the RA cohort as compared with OA (MD: 4.78, 95% CI: 2.25-7.30, p = .0002, I2 = 80%). Conclusion: RA was associated with fewer vascular complications, but at a cost of higher incidence of myocardial infarction and higher fluoroscopy time compared with OA, at short term follow-up. OA is a safe and effective alternative for the management of CAC.

A Case of McLeod's Syndrome Presenting with Severe Decompensated Heart Failure.

McLeod's syndrome (MLS) is an X-linked disorder caused by mutations in the XK gene with neurological manifestations as well as cardiomyopathy. This is a case of acute exacerbation of heart failure in a 44-year-old White male with a confirmed diagnosis of MLS, which was managed with guideline-directed medical therapy and placement of an implantable cardioverter defibrillator with recovery in ejection fraction.

Incidence, Current Guidelines and Management of Gastrointestinal Bleeding after Transcatheter Aortic Valve Replacement: A Systematic Review.

BACKGROUND: There is a significant increase in morbidity and mortality in patients complicated by major bleeding following transcatheter aortic valve replacement (TAVR). It has become more challenging to manage such complications when the patient needs to be on anticoagulation or antiplatelet agent post-procedure to prevent thrombotic/embolic complications. METHODS: We systematically reviewed all available randomized controlled trials and observational studies to identify incidence rates of gastrointestinal bleeding post-procedure. After performing a systematic search, a total of 8731 patients from 15 studies (5 RCTs and 10 non-RCTs) were included in this review. RESULTS: The average rate of gastrointestinal bleeding during follow-up was 3.0% in randomized controlled trials and 1.9% among observational studies. CONCLUSION: Gastrointestinal bleeding has been noted to be higher in the RCTs as compared to observational studies. This review expands knowledge of current guidelines and possible management of patients undergoing TAVR.

Characteristics and Outcomes of Early vs Late Initiation of Mechanical Circulatory Support in Non-Acute Myocardial Infarction related Cardiogenic Shock: An Analysis of the National Inpatient Sample Database.

Cardiogenic shock (CS) is significant cause of mortality. The use of mechanical circulatory support (MCS) in patients with non-acute myocardial infarction (Non-AMI) CS is lacking. We inquired data regarding the trends and outcomes early vs late initiation of MCS in non-AMI CS. We investigated National Inpatient Sample database between October 2015-December 2018, identifying hospitalizations with CS, either complicated by AMI or Non-AMI. Patients were divided into 2 cohorts, early initiation of MCS (<48 hours) and late initiation of MCS (>48 hours). The primary analysis included death within first 24 hours. A secondary analysis was adjusted after excluding patients who died in first 24 hours. A total of 85,318 patients with non-AMI-related CS with MCS placement were identified. Among this cohort, 54.6% (n=46,579) underwent early initiation of MCS within 48 hours, and 45.4% (n=38,739) underwent late initiation of MCS after 48 hours. In primary analysis, early MCS initiation was associated with more in-hospital mortality in primary outcome of all-cause hospital mortality (35.72% vs 27.63%, P<0.0001, OR 1.44, 95% CI: 1.40-1.49, P<0.0001), however, adjusted secondary analysis showed a statistically significant decrease in all-cause hospital mortality (23.63% vs 27.63%, P<0.0001, OR 0.80, 95% CI: 0.78-0.83, P<0.0001). In non-AMI-related CS and based on survival to 24 hours after admission, early initiation of MCS had statistically significant decrease in all-cause hospital mortality, with less incidence of vascular and renal complications, and shorter hospital stay. Late initiation of MCS was associated with a higher incidence of advanced therapies, including LVAD and transplant.

Rising trend of acute myocardial infarction among young cannabis users: A 10-year nationwide gender and race stratified analysis.

Background: The use of cannabis has massively increased among younger patients due to increasing legalization and availability. Methods: We performed a retrospective nationwide study using the Nationwide inpatient sample (NIS) database to analyze the trends of acute myocardial infarction (AMI) in young cannabis users and related outcomes among patients aged 18-49 years from 2007 to 2018, using ICD-9 and ICD-10 codes. Results: Out of 819,175 hospitalizations, 230,497 (28%) admissions reported using cannabis. There was a significantly higher number of males (78.08% vs. 71.58%, p < 0.0001) and African Americans (32.22% vs. 14.06%, p < 0.0001) admitted with AMI and reported cannabis use. The incidence of AMI among cannabis users consistently increased from 2.36% in 2007 to 6.55% in 2018. Similarly, the risk of AMI in cannabis users among all races increased, with the biggest increase in African Americans from 5.69% to 12.25%. In addition, the rate of AMI in cannabis users among both sexes showed an upward trend, from 2.63% to 7.17% in males and 1.62%-5.12% in females. Conclusion: The incidence of AMI in young cannabis users has increased in recent years. The risk is higher among males and African Americans.

Racial disparities in ventricular tachycardia in young adults: analysis of national trends.

BACKGROUND: In the last two decades, risk factors, prevalence, and mortality due to coronary artery disease in young adults are on the rise. We sought to assess the prevalence, trends, and economic burden of ventricular tachycardia (VT) hospitalizations in young adults (< 45 years), further stratified by race and gender. METHODS: The Nationwide Inpatient Sample was explored for hospitalizations with VT in patients (< 45 years) between 2005 and 2018 and divided among 3 groups of the quadrennial period using validated International Classification of Diseases (ICD) 9th and 10th revision Clinical Modification (CM) codes. The Pearson chi-square test and Wilcoxon rank-sum were used for categorical and continuous variables, respectively. We assessed the temporal trends of mortality in VT hospitalizations and trends of VT hospitalization stratified by age, sex, and race by using Joinpoint regression analysis. The primary outcome was in-hospital mortality trends. Secondary outcomes were trends of hospital stay in days, cost of care in US dollars, cardiac arrest, and discharge disposition. RESULTS: Out of 5,156,326 patients admitted with VT between 2005 and 2018, 309,636 were young adults. Among them, 102,433 were admitted between 2005 and 2009 (mean age 36.1 ± 6.99; 61% male, 58.5% White), 109,591 between 2010 and 2014 (mean age 35.5 ± 7.16; 59% male, 54.2% White), and 97,495 between 2015 and 2018 (mean age 35.4 ± 7.00; 60% male, 52.3% White) (p < 0.07). In the young adults with VT, all-cause mortality was 7.37% from 2005 to 2009, 7.85% from 2010 to 2014 (6.5% relative increase from 2005 to 2009), and 8.98% from 2015 to 2018 (relative increase of 14.4% from 2010 to 2014) (p < 0.0001). Similarly, risk of cardiac arrest was on the rise (6.15% from 2005 to 2009 to 7.77% in 2010-2014 and 9.97% in 2015-2018). Inflation-adjusted cost increased over the years [$12,177 in 2005-2009; $13,249 in 2010-2014; $15,807 in 2015-2018; p < 0.0001)]. CONCLUSIONS: VT hospitalizations and related all-cause mortality, and healthcare utilization costs in young adults are on the rise in the study period. Hospitalization burden related to VT and poor outcomes were more notable for Black adults. Further studies are required for targeted screening and preventative measures in young adults.

Safety of catheter ablation for atrial fibrillation in patients with cancer: a nationwide cohort study.

BACKGROUND: Atrial fibrillation (AF) is the most common arrhythmia in patients with cancer, especially breast, gastrointestinal, respiratory, urinary tract, and hematological malignancies. Catheter ablation (CA) is a well-established, safe treatment option in healthy patients; however, literature regarding safety of CA for AF in patients with cancer is limited and confined to single centers. OBJECTIVE: We aimed to assess the outcomes and peri-procedural safety of CA for AF in patients with certain types of cancer. METHODS: The NIS database was queried between 2016 and 2019 to identify primary hospitalizations with AF and CA. Hospitalizations with secondary diagnosis of atrial flutter and other arrhythmias were excluded. Propensity score matching was used to balance the covariates between cancer and non-cancer groups. Logistic regression was used to analyze the association. RESULTS: During this period, 47,765 CA procedures were identified, out of which 750 (1.6%) hospitalizations had a diagnosis of cancer. After propensity matching, hospitalizations with cancer diagnosis had higher in-hospital mortality (OR 3.0, 95% CI 1.5-6.2, p = 0.001), lower home discharge rates (OR 0.7, 95% CI 0.6-0.9, p < 0.001) as well as other complications such as major bleeding (OR 1.8, 95% CI 1.3-2.7, p = 0.001) and pulmonary embolism (OR 6.1, 95% CI 2.1-17.8, p < 0.001) but not associated with any major cardiac complications (OR 1.2, 95% CI 0.7-1.8, p = 0.53). CONCLUSION: Patients with cancer who underwent CA for AF had significantly higher odds of in-hospital mortality, major bleeding, and pulmonary embolism. Further larger prospective observational studies are needed to validate these findings.

Impact of Atrial Fibrillation on Outcomes in Patients Hospitalized With Nontraumatic Intracerebral Hemorrhage.

Objective: To assess the effect of atrial fibrillation (AF) on outcomes in hospitalizations for non-traumatic intracerebral hemorrhage (ICH). Patients and Methods: We queried the National Inpatient Sample database between January 1, 2016, and December 31, 2019, to identify hospitalizations with an index diagnosis of non-traumatic ICH using ICD-10 code I61. The cohort was divided into patients with and without AF. Propensity score matching was used to balance the covariates between AF and non-AF groups. Logistic regression was used to analyze the association. All statistical analyses were performed using weighted values. Results: Our cohort included 292,725 hospitalizations with a primary discharge diagnosis of non-traumatic ICH. From this group, 59,005 (20%) recorded a concurrent diagnosis of AF, and 46% of these patients with AF were taking anticoagulants. Patients with AF reported a higher Elixhauser comorbidity index (19.8±6.0 vs 16.6±6.4; P<.001) before propensity matching. After propensity matching, the multivariate analysis reported that AF (aOR, 2.34; 95% CI, 2.26-2.42; P<.001) and anticoagulation drug use (aOR, 1.32; 95% CI, 1.28-1.37; P<.001) were independently associated with all-cause in-hospital mortality. Moreover, AF was significantly associated with respiratory failure requiring mechanical ventilation (odds ratio, 1.57; 95% CI, 1.52-1.62; P<.001) and acute heart failure (odds ratio, 1.26; 95% CI, 1.19-1.33; P<.001) compared with the absence of AF. Conclusion: These data suggest that non-traumatic ICH hospitalizations with coexistent AF are associated with worse in-hospital outcomes such as higher mortality and acute heart failure.

Impact of timing of transvenous lead removal on outcomes in infected cardiac implantable electronic devices.

BACKGROUND: Cardiovascular implantable electronic device (CIED) infections are associated with increased mortality and morbidity. OBJECTIVE: This study sought to evaluate the impact of early vs delayed transvenous lead removal (TLR) on in-hospital mortality and outcomes in patients with CIED infection. METHODS: Using the nationally representative, all payer, Nationwide Readmissions Database, we evaluated patients undergoing TLR for CIED infection between January 1, 2016, and December 31, 2018. The timing of TLR was determined on the basis of hospitalization days after the initial admission for CIED infection. The impact of early (≤7 days) vs delayed (>7 days) TLR on mortality and major adverse events was studied. RESULTS: Of the 12,999 patients who underwent TLR for CIED infection, 8834 (68%) underwent early TLR and 4165 (32%) underwent delayed TLR. Delayed TLR was associated with a significant increase in in-hospital mortality (8.3% vs 3.5%; adjusted odds ratio 1.70; 95% confidence interval 1.43-2.03; P < .001). Subgroup analysis of patients with CIED infection and systemic infection showed that delayed TLR in patients with systemic infection was associated with a higher rate of in-hospital mortality compared with early TLR (10.4% vs 7.5%; adjusted odds ratio 1.24; 95% confidence interval 1.04-1.49; P < .019). Delayed TLR was also associated with significantly higher adjusted odds of major adverse events and postprocedural length of stay. CONCLUSION: These data suggest that delayed TLR in patients with CIED infection is associated with increased in-hospital mortality and major adverse events, especially in patients with systemic infection.

Outcomes, Trends, and Predictors of Gastrointestinal Bleeding in Patients Undergoing Transcatheter Aortic Valve Implantation (from the National Inpatient Sample).

Major bleeding has been identified as one of the most common complications after transcatheter aortic valve implantation (TAVI) with some suffering gastrointestinal bleeding (GIB). This study aimed at assessing the incidence and predictors of GIB after TAVI in the United States. We performed a retrospective analysis of data from the National Inpatient Sample database from 2011 to 2018. A total of 216,023 hospitalizations for TAVI were included. Of the included patients, 2,188 (1%) patients had GIB, whereas 213,835 (99%) patients did not have GIB. The presence of arteriovenous malformation was associated with the highest odds of having a gastrointestinal bleed (odds ratio (OR) 24.8, 95% confidence interval (CI) 17.13 to 35.92). Peptic ulcer disease was associated with an eightfold increased risk of bleeding (OR 8.74, 95% CI, 6.69 to 11.43) followed closely by colorectal cancer (OR 7.89, 95% CI, 5.33 to 11.70). Other comorbidities that were associated with higher propensity-matched rates of GIB were chronic kidney disease (OR 1.27,95% CI, 1.14 to 1.41), congestive heart failure (OR 1.18, 95% CI,1.06 to 1.32), liver disease (OR1.83, 95% CI,1.53 to 2.19), end-stage renal disease (OR 2.08,95% CI, 1.75 to 2.47), atrial fibrillation (OR1.63,95% CI,  1.49 to 1.78), and lung cancer (OR 2.80, 95% CI,1.77 to 4.41). Patients with GIB had higher propensity-matched rates of mortality than those without GIB, (12.1% vs 3.2%, p <0.01). Patients with GIB had a higher median cost of stay ($68,779 vs $46,995, p <0.01) and a longer length of hospital stay (11 vs 3 days, p <0.01). In conclusion, health care use and mortality are higher in hospitalizations of TAVI with a GIB. Baseline comorbidities like peptic ulcer disease, chronic kidney disease, liver disease, atrial fibrillation and, colorectal cancer are significant predictors of this adverse event.

Meta-analysis Comparing Percutaneous Coronary Intervention With Coronary Artery Bypass Grafting for Non-ST Elevation Acute Coronary Syndrome in Patients With Multivessel or Left Main Disease.

Outcomes of patients presenting with non-ST-elevation acute coronary syndrome (NSTE-ACS) with multivessel coronary disease (MVD) and/or unprotected left main coronary artery disease (CAD) revascularized with percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) is not well defined. MEDLINE/PubMed and EMBASE/Ovid were queried for studies that investigated PCI vs CABG in this disease subset. The primary outcome was major cardiac adverse events (MACE) at 30 days and long-term follow-up (3-5 years). The final analysis included 9 studies with a total of 9299 patients. No significant difference was observed between PCI and CABG in 30 days MACE (risk ratio [RR] 0.96; 95% confidence interval [CI] 0.38-2.39, all-cause mortality, myocardial infarction, and stroke. A meta-regression analysis revealed patients with a history of PCI had higher risk of MACE with PCI as compared with CABG. At long-term follow-up, PCI compared with CABG was associated with higher risk of MACE (RR 1.52; 95% CI 1.28-1.81), myocardial infarction, and repeat revascularization, while no difference was observed in the risk of stroke and all-cause mortality. In patients with NSTE-ACS and MVD or unprotected left main CAD, no differences were observed in the clinical outcomes between PCI and CABG at 30 days follow-up. With long-term follow-up, PCI was associated with a higher risk of MACE.

Impact of Arrhythmias on Hospitalizations in Patients With Cardiac Amyloidosis.

Cardiac involvement in amyloidosis is associated with a poor prognosis. Data on the burden of arrhythmias in patients with cardiac amyloidosis (CA) during hospitalization are lacking. We identified the burden of arrhythmias using the National Inpatient Sample (NIS) database from January 2016 to December 2017. We compared patient characteristics, outcomes, and hospitalization costs between CA patients with and without documented arrhythmias. Out of 5,585 hospital admissions for CA, 2,020 (36.1%) had concurrent arrhythmias. Propensity-score matching for age, sex, income, and co-morbidities was performed with 1,405 CA patients with arrhythmias and 1,405 patients without. The primary outcome of all-cause mortality was significantly higher in CA patients with arrhythmia than without(13.9% vs 5.3%, p-value <0.001). Atrial fibrillation (AF) was the most common (72.2%) arrhythmia in CA patients with concurrent arrhythmia. The secondary outcomes of AF-related mortality (11.95% vs 9.16%, p-value = 0.02) and acute and acute on chronic as heart failure (HF) exacerbation (32.38% vs 24.91%, p-value <0.0001) were significantly higher in CA and concurrent arrhythmia compared with CA patients without. The total length of hospital stay (6[3 to 12] vs 5[3 to 10], p-value <0.001) and cost of hospitalization were ($ 15,086[7,813 to 30,373] vs $ 12,219[6,865 to 23,997], p-value = 0.001) were significantly greater among CA with arrhythmia compared with those without. These data suggest that the presence of arrhythmias in CA patients during hospital admission is associated with a poorer prognosis and may reflect patients with a higher risk of HF exacerbation and mortality.

Same-day discharge after transcatheter mitral valve repair using MitraClip in a tertiary community hospital: a case series.

BACKGROUND: Due to the current Coronavirus Disease 2019 (COVID-19) pandemic, there is a realization for innovation in procedures and protocols to minimize hospital stay and at the same time ensure continued evidence-based treatment delivered to the patients. We present a same-day discharge protocol for transcatheter mitral valve repair (TMVR) using MitraClip under general anaesthesia in a six-patient case series. This protocol aims to reduce the length of hospital stay, thereby minimizing potential for nosocomial COVID-19 infections and to promote safe discharge with cautious follow-up. CASE SUMMARY: Six patients with severe symptomatic mitral valve (MV) regurgitation underwent successful transfemoral MV repair using standard procedures. Following repair, patients were monitored on telemetry in the recovery area for 3 h, ambulated to assess vascular access stability and underwent post-procedural transthoracic echocardiogram to assess for any pericardial effusion or post-procedural prosthetic mitral stenosis. CONCLUSION: Same-day discharge after TMVR is possible when done cautiously with close follow-up, can minimize hospital stay, improve resource utilization, and reduce risk of nosocomial COVID-19 infection.
