Impact of same-admission percutaneous coronary intervention on periprocedural outcomes of transcatheter aortic valve implantation.

Background: Current guidelines recommend percutaneous coronary intervention (PCI) prior to transcatheter aortic valve implantation (TAVI) if significant coronary artery disease is present, but whether PCI should be done in the same admission as TAVI is not determined. Methods: We retrospectively analyzed the National Inpatient Sample from 2016 to 2019 to compare TAVI with and without same-admission PCI and compare in-hospital outcomes after propensity score matching. Results: Among 170,030 hospitalizations for TAVI, 4425 (2.6%) had same-admission PCI performed. After propensity score matching, 4425 hospitalizations were allocated to those with and without same-admission PCI. No difference in in-hospital mortality (odds ratio [OR] 1.59, 95% confidence interval [CI] 0.81-3.12) was observed between the two groups. However, TAVI with same-admission PCI was associated with higher odds of cardiac arrest (OR 2.25, 95% CI 1.02-4.98), cardiogenic shock (OR 2.21, 95% CI 1.29-3.79), and acute myocardial infarction (OR 3.23, 95% CI 2.11-4.93). It was also associated with longer length of stay and more expensive hospital cost. Conclusion: TAVI with same-admission PCI was associated with higher odds of periprocedural complications and higher immediate cost. Our findings should be interpreted in the context of the same-admission PCI and TAVI cohort potentially being sicker and the isolated TAVI control group may or may not having obstructive coronary artery disease.

Impact of cardiac and noncardiac cirrhosis on coronary revascularization outcomes from the National Inpatient Sample, 2016 to 2018.

Data on coronary revascularization in patients with cirrhosis are scarce because it is often deferred in the setting of significant comorbidities and coagulopathies. It is unknown whether patients with cardiac cirrhosis have a worse prognosis. The National Inpatient Sample was surveyed to identify patients who underwent percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) for acute coronary syndrome (ACS) from 2016 to 2018. Those with and without liver cirrhosis were propensity score-matched and compared within the PCI and CABG cohorts. Primary outcome was in-hospital mortality. Patients with cirrhosis were further classified into cardiac and noncardiac cirrhosis and their in-hospital mortalities were compared. A total of 1,069,730 PCIs and 273,715 CABGs were performed for ACS, of which 0.6% and 0.7%, respectively, were performed in patients with cirrhosis. In both the PCI cohort (odds ratio = 1.56; 95% confidence interval, 1.10-2.25; P = 0.01) and the CABG cohort (odds ratio = 2.34; 95% confidence interval, 1.19-4.62; P = 0.01), cirrhosis was associated with higher in-hospital mortality. In-hospital mortality was greatest in cardiac cirrhosis (8.4% and 7.1%), followed by noncardiac cirrhosis (5.5% and 5.0%) and no cirrhosis (2.6% and 2.3%) in PCI and CABG cohorts, respectively. Higher in-hospital mortality and periprocedural morbidities should be considered when performing coronary revascularization in patients with cirrhosis.

Factor Xa inhibitors versus vitamin K antagonist in morbidly obese patients with venous thromboembolism: a systematic review and meta-analysis.

INTRODUCTION: Guidelines have endorsed non-vitamin K antagonist oral anticoagulants (NOACs), consisting of factor Xa inhibitors (xabans) and direct thrombin inhibitors, as the first line of treatment in venous thromboembolism (VTE) and atrial fibrillation. However, morbidly obese patients were under-represented in landmark trials of NOACs. Therefore, this study aimed to systematically review and perform a meta-analysis of studies on xabans versus vitamin K antagonist (VKA) in this high-risk population with VTE. METHODS: PubMed, Embase, Medline, Cochrane library, and Google Scholar databases were searched to identify studies that compared xabans and VKA in treating morbidly obese patients with VTE. Morbid obesity was defined as body weight ≥ 120 kg or BMI ≥ 40 kg/m2. Outcomes of interest included recurrent VTE, major bleeding, and clinically relevant non-major bleeding (CRNMB). RESULTS: Eight studies comprising 30,895 patients were included. A total of 12,755 patients received xabans while 18,140 received VKAs. No significant difference in the odds of recurrent VTE (OR 0.75, 95% CI 0.55-1.01) and CRNMB (OR 0.69, 95% CI 0.44-1.09) was observed between the xabans group and the VKA group. However, the xabans group was associated with lower odds of major bleeding (OR 0.70, 95% CI 0.59-0.83). CONCLUSION: Xabans have lower odds of major bleeding but similar odds of recurrent VTE when compared with VKAs in treating VTE in morbidly obese patients. Large registry analyses or future randomized controlled trials will be helpful in confirming these findings.

Impact of end-stage renal disease on in-hospital outcomes of hypertensive emergency from the National Inpatient Sample, 2016 to 2018.

The prevalence and incidence of end-stage renal disease (ESRD) has been increasing. However, data on inpatient outcomes of hypertensive emergencies in patients with ESRD are lacking. We performed a retrospective study using the largest inpatient database in the United States. Hospitalizations for hypertensive emergency between 2016 and 2018 were identified from the National Inpatient Sample. Propensity score matching was performed between those with and without ESRD. The primary outcome was in-hospital mortality, and secondary outcomes included end-organ complications of hypertensive emergency. Multivariable logistic regression was used to identify potential risk factors of in-hospital mortality. Of 105,565 hospitalizations for hypertensive emergency, 15% occurred in patients with ESRD. Hospitalizations for hypertensive emergency in patients with ESRD were associated with higher odds of cardiac arrest (odds ratio [OR] 4.52, 95% confidence interval [CI] 1.53-13.3, P = 0.01) and acute pulmonary edema (OR 2.80, 95% CI 2.15-3.65, P < 0.01) and a longer hospital stay (mean difference 1.15 days, 95% CI 0.88-1.43, P < 0.01). Age ≥65 years, obesity, atrial fibrillation, and malnutrition were associated with higher odds of in-hospital mortality. Our findings demonstrate the excess morbidities in patients with ESRD admitted for hypertensive emergency.

Prevalence of Post-Heart Transplant Malignancies: A Systematic Review and Meta-Analysis.

The prevalence of different cancers after heart transplant (HT) is unclear due to small and conflicting prior studies. Herein, we report a systematic review and meta-analysis to highlight the prevalence and pattern of malignancies post-HT. We conducted an extensive literature search on PubMed, Scopus, Cochrane databases for prospective or retrospective studies reporting malignancies after HT. The proportions from each study were subjected to random effects model that yielded the pooled estimate with 95% confidence intervals (CI). Fifty-five studies comprising 60,684 HT recipients reported 7759 total cancers during a mean follow-up of 9.8 ± 5.9 years, with an overall incidence of 15.3% (95% CI = 12.7%-18.1%). Mean time from HT to cancer diagnosis was 5.1 ± 4 years. The most frequent cancers were gastrointestinal (7.6%), skin (5.7%), and hematologic/blood (2.5%). Meta-regression showed no association between incidence of cancer and mean age at HT (coeff: -0.008; P = 0.25), percentage of male recipients (coeff: -0.001; P = 0.81), donor age (coeff: -0.011; P = 0.44), 5-year (coeff: 0.003; P = 0.12) and 10-year (coeff: 0.02; P = 0.68) post-transplant survival. There is a substantial risk of malignancies in HT recipients, most marked for gastrointestinal, skin, and hematologic. Despite their occurrence, survival is not significantly impacted.

AMSTAR 2 appraisal of systematic reviews and meta-analyses in the field of heart failure from high-impact journals.

BACKGROUND: The Measurement Tool to Assess systematic Reviews (AMSTAR) 2 is a critical appraisal tool for systematic reviews (SRs) and meta-analyses (MAs) of interventions. We aimed to perform the first AMSTAR 2-based quality assessment of heart failure-related studies. METHODS: Eleven high-impact journals were searched from 2009 to 2019. The included studies were assessed on the basis of 16 domains. Seven domains were deemed critical for high-quality studies. On the basis of the performance in these 16 domains with different weights, overall ratings were generated, and the quality was determined to be "high," "moderate," "low," or "critically low." RESULTS: Eighty-one heart failure-related SRs with MAs were included. Overall, 79 studies were of "critically low quality" and two were of "low quality." These findings were attributed to insufficiency in the following critical domains: a priori protocols (compliance rate, 5%), complete list of exclusions with justification (5%), risk of bias assessment (69%), meta-analysis methodology (78%), and investigation of publication bias (60%). CONCLUSIONS: The low ratings for these potential high-quality heart failure-related SRs and MAs challenge the discrimination capacity of AMSTAR 2. In addition to identifying certain areas of insufficiency, these findings indicate the need to justify or modify AMSTAR 2's rating rules.

The prognostic implications of ST-segment and T-wave abnormalities in patients undergoing regadenoson stress SPECT myocardial perfusion imaging.

BACKGROUND: The prognostic implications of ST-segment and T-wave (ST/T) abnormalities in patients undergoing stress SPECT-myocardial perfusion imaging (MPI) are not well defined. METHODS AND RESULTS: This was a single-center, retrospective cohort study of consecutive patients who underwent regadenoson stress SPECT-MPI. Patients with baseline electrocardiogram (ECG) abnormalities that impede ST/T analysis or those with known coronary artery disease were excluded. Patients were categorized as having primary ST abnormalities, secondary ST/T abnormalities due to ventricular hypertrophy or right bundle branch block, T-wave abnormalities, or normal ECG. The primary outcome was major adverse cardiovascular events (MACE) defined as the composite of cardiac death or myocardial infarction. Among 6,059 subjects, 1912 (32%) had baseline ST/T abnormalities. During a mean follow-up of 2.3 ± 1.9 years, the incidence of MACE was significantly higher among patients with secondary ST/T abnormalities compared to those with normal ECG (HR 2.05; 95% confidence interval [CI], 1.04-4.05; P = 0.039). No significant difference in MACE was observed among patients with primary ST abnormalities (HR 1.64; CI 0.87-3.06; P = 0.124) or T-wave abnormalities (HR 1.15; CI 0.62-2.16; P = 0.658) compared with patients who had normal ECG. Among patients with secondary ST/T changes, abnormal MPI was not associated with a significant increase in MACE rates compared to normal MPI (HR 1.18; CI 0.31-4.58; P = 0.808). However, abnormal MPI was associated with higher MACE rates among patients with primary ST abnormalities (HR 4.50; CI 1.44-14.10; P = 0.005) and T-wave abnormalities (HR 3.74; CI 1.20-11.68; P = 0.015). Similarly, myocardial ischemia on regadenoson stress SPECT-MPI was not associated with a significant increase in MACE rates in patients with secondary ST/T abnormalities (HR 1.45; CI 0.38-5.61; P = 0.588), while it was associated with a higher incidence of MACE in patients with primary ST abnormalities (HR 3.012; CI 0.95-9.53; P = 0.049) and T-wave abnormalities (HR 5.06; CI 1.60-15.96; P = 0.002). CONCLUSION: While patients with secondary ST/T abnormalities had significantly higher MACE risk, abnormal MPI or presence of myocardial ischemia on regadenoson SPECT-MPI in this group does not add prognostic information. Patients with primary ST abnormalities and T-wave abnormalities do not seem to have a significantly higher MACE risk compared to those with normal ECG; however, abnormal MPI or presence of myocardial ischemia, in these groups, correlates with higher MACE rates.

Outcomes of atrial fibrillation hospitalizations in patients with systemic lupus erythematosus: a report from the national inpatient sample.

This study compares outcomes of patients admitted for atrial fibrillation (AF) with and without coexisting systemic lupus erythematosus (SLE). The primary outcome was inpatient mortality. Hospital length of stay (LOS), total hospital charges, odds of undergoing ablation, pharmacologic cardioversion and electrical cardioversion were secondary outcomes of interest. Data were abstracted from the National Inpatient Sample (NIS) 2016 and 2017 database. The NIS was searched for adult hospitalizations with AF as principal diagnosis with and without SLE as secondary diagnosis using International Classification of Diseases, Tenth Revision, Clinical Modification codes. Multivariate logistic and linear regression analysis was used accordingly to adjust for confounders. There were over 71 million discharges included in the combined 2016 and 2017 NIS database. 821,630 hospitalizations were for adult patients, who had a principal diagnosis of AF, out of which, 2645 (0.3%) had SLE as secondary diagnosis. Hospitalizations for AF with SLE had similar inpatient mortality (1.5% vs 0.91%, adjusted OR (AOR): 1.0, 95% CI 0.47 to 2.14, p=0.991), LOS (4.2 vs 3.4 days, p=0.525), total hospital charges ($51,351 vs $39,121, p=0.056), odds of undergoing pharmacologic cardioversion (0.38% vs 0.38%, AOR: 0.90, 95% CI 0.22 to 3.69, p=0.880) and electrical cardioversion (12.9% vs 17.5%, AOR 0.87, 95% CI 0.66 to 1.15, p=0.324) compared with those without SLE. However, SLE group had increased odds of undergoing ablation (6.8% vs 4.2%, AOR: 1.9, 95% CI 1.3 to 2.7, p<0.0001). Patients admitted for AF with SLE had similar inpatient mortality, LOS, total hospital charges, likelihood of undergoing pharmacologic and electrical cardioversion compared with those without SLE. However, SLE group had greater odds of undergoing ablation.

A Meta-analysis and Systematic Review of Valvular Heart Disease in Systemic Lupus Erythematosus and Its Association With Antiphospholipid Antibodies.

BACKGROUND: Valvular heart disease (VHD) is a known cardiac manifestation of systematic lupus erythematosus (SLE). This systematic review aims to pool data from studies to estimate the frequency of valvular lesions in SLE patients. It also aims to demonstrate the association between VHD in SLE and antiphospholipid antibodies positivity. METHODS: We included 27 studies after identifying relevant abstracts from PubMed, Scopus, and Google Scholar from the time of inception of database to 2019. Inclusion criteria consisted of English-language case-control and cohort studies. Three reviewers independently performed study selection, data extraction, and quality assessment using the Newcastle-Ottawa Scale for assessing risk for bias. RESULTS: For VHD in SLE patients, the most commonly involved valve was the mitral valve, with 19.7% lesions being mitral regurgitation. In terms of morphological lesions, valve thickening (11.06%) and vegetations (11.76%) were among the most prevalent. Other commonly encountered lesions were mitral valve prolapse and tricuspid regurgitation in 9.25% and 10.86% of patients, respectively. A meta-analysis of 21 studies with 2163 SLE patients, of which 23.3% had valvular lesions, showed a significant association of anticardiolipin antibodies positivity with VHD (relative risk, 1.55; confidence interval, 1.10-2.18). CONCLUSIONS: Systemic lupus erythematosus is associated with VHD, and it should be considered a clinical manifestation of SLE in the absence of other valvular pathologies. There is a clear association between VHD in SLE and immunoglobulin G anticardiolipin antibodies positivity. This association suggests that this subgroup of SLE patients might benefit from a screening echocardiogram.

BRASH Syndrome with Hyperkalemia: An Under-Recognized Clinical Condition.

BRASH syndrome is characterized by bradycardia, renal failure, use of an atrioventricular nodal blocker (AVNB), shock, and hyperkalemia. These symptoms represent an ongoing vicious cycle in a patient with a low glomerular filtration rate taking an AVNB. Decreased clearance of the medication and hyperkalemia associated with renal failure synergize to cause bradycardia and hypoperfusion. This reaction causes renal function to worsen, thereby perpetuating the cycle of BRASH syndrome.

Deaths from heart failure and cancer: location trends.

BACKGROUND: Increasing utilisation of hospice services has been a major focus in oncology, while only recently have cardiologists realised the similar needs of dying patients with heart failure (HF). We examined recent trends in locations of deaths in these two patient populations to gain further insight. METHODS: Complete population-level data were obtained from the Mortality Multiple Cause-of-Death Public Use Record from the National Center for Health Statistics database, from 2013 to 2017. Location of death was categorised as hospital, home, hospice facility or nursing facility. Demographic characteristics evaluated by place of death included age, sex, race, ethnicity, marital status and education, and a multivariable logistic regression analysis was performed to analyse possible associations. RESULTS: Among 2 780 715 deaths from cancer, 27% occurred in-hospital and 14% in nursing facilities; while among 335 350 HF deaths, 27% occurred in-hospital and 30% in nursing facilities. Deaths occurred at hospice facilities in 14% of patients with cancer, compared with just 8.7% in HF (p=0.001). For both patients with HF and cancer, the proportion of at-home and in-hospice deaths increased significantly over time, with majority of deaths occurring at home. In both cancer and HF, patients of non-Hispanic ethnicity (cancer: OR 1.29, (1.27 to 1.31), HF: OR 1.14, (1.07 to 1.22)) and those with some college education (cancer: OR 1.10, (1.09 to 1.11); HF: OR 1.06, (1.04 to 1.09)) were significantly more likely to die in hospice. CONCLUSION: Deaths in hospital or nursing facilities still account for nearly half of cancer or HF deaths. Although positive trends were seen with utilisation of hospice facilities in both groups, usage remains low and much remains to be achieved in both patient populations.

Rare Presentation of Cardiac Tamponade in a Patient With Subclinical Hypothyroidism.

Cardiovascular effects of hypothyroidism include bradycardia, diastolic hypertension, atrial fibrillation, prolonged QT interval leading to torsades de pointes, varying degrees of AV block, accelerated coronary artery disease, and pericardial effusion. Cardiac tamponade is rare in patients with hypothyroidism because of pericardial distensibility and slow accumulation of fluid. The amount and rate of accumulation of pericardial effusion are related to the severity of hypothyroidism. Though rare, significant pericardial effusion can be a manifestation of subclinical hypothyroidism.

Systemic Lupus Erythematosus: An Overview of the Disease Pathology and Its Management.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with varied natural history and multisystemic involvement. The pathogenesis is multifactorial and complex precipitating the formation of autoantibodies. One of the main factors in SLE is the interaction between environmental triggers and genetic factors. Genome-wide association study technology has led to the identification of more than 80 loci which produce key proteins that lead to small pathophysiological changes and are associated with SLE. There has been an improvement in the management of the disease with newly standardized scores that have been validated in assessing disease activity and quality of life, and have helped in clinical care as well as research. The last five decades have seen a marked improvement in the prognosis of SLE, thanks to better general care and the development of newer immunosuppressive drugs, more specifically biological agents.

Managing Chronic Pain in the Elderly: An Overview of the Recent Therapeutic Advancements.

A majority of the elderly suffer from chronic pain that significantly alters their daily activities and imposes an enormous burden on health care. Multiple comorbidities and the risk of polypharmacy in the elderly make it a challenge to determine the appropriate drug, dosage, and maintenance of therapy. Opioids are the most commonly used agents for this purpose in the elderly. The aim of this article is to discuss both the current well-established therapies used for managing chronic pain in the elderly and also the emerging newer therapies.
