30-day readmission following urgent and elective transcatheter aortic valve replacement: A Nationwide Readmission Database analysis.

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is being increasingly used for decompensated severe symptomatic aortic stenosis. Data on urgent and elective TAVR readmission is scarce in the literature. Here, we have performed a retrospective cohort study with the Nationwide Readmission Database of 2016 to identify the rate of 30-day all-cause readmission, common causes of readmission, and distribution of morbidity in index admission and readmission after urgent and elective TAVR. METHODS: We used International Classification of Diseases, Tenth Revision codes (02R.F38H, 02R.F38Z, 02R.F48Z) for identification of all TAVR procedures done in 2016 in patients >18 years old. We found 8379 patients who underwent urgent TAVR and 32,006 patients who underwent elective TAVR in 2016. RESULT: The mean age of patients undergoing urgent TAVR was 79 ± 9.97 years with 44.6% women. The mean age of patients undergoing elective TAVR was 80.7 ± 8.25 years with 46.2% women. We found the 30-day all-cause readmission rate of 15.5% and 9.5% in patients undergoing urgent and elective TAVR, respectively (p < 0.001). The cardiac cause was the predominant cause of readmission in both groups (43.77% vs. 42.11%, p = 0.57), followed by pulmonary cause, gastrointestinal (GI) cause, and renal cause. Among cardiac causes, congestive heart failure (CHF) was predominant cause of readmission and was similar in both groups (18.73 in urgent TAVR vs. 15.73 in elective TAVR, p = 0.12). CONCLUSION: We found that the all-cause 30-day readmission rate was higher in patients who had undergone urgent TAVR. Further studies are needed to better understand this difference.

Advances in the Pharmacogenomics of Antiplatelet Therapy.

BACKGROUND: Acute coronary syndrome (ACS) is a highly thrombotic state, and a sustained antiplatelet effect is vital to the prevention of thrombotic complications. Clopidogrel, the most widely used oral P2Y12 receptor antagonist in ACS, has attracted considerable attention because of significant variability in antiplatelet effect depending on the presence of CYP2C19 allele. Other P2Y12 receptor antagonists offer sustained and more predictable antiplatelet effects than clopidogrel albeit at an increased cost. Several studies have demonstrated the promising application of pharmacogenetics in choosing personalized antiplatelet therapy using the point-of-care genotype assays. AREAS OF UNCERTAINTY: Guidelines regarding the genotype-guided approach to the selection of antiplatelet therapy have been conflicting, and studies evaluating the effect of pharmacogenetic-guided selection of antiplatelet therapy on the outcomes have demonstrated mixed results. DATA SOURCES: A literature search was conducted using MEDLINE and EMBASE for studies reporting the association of pharmacogenetic-guided selection of antiplatelet therapy and the outcomes in patients with ACS until December 2018. RESULTS: Presence of specific CYP2C19 allele significantly influences clopidogrel metabolism and associated outcomes in patients with ACS. Thrombotic and bleeding complications are more common in patients with loss-of-function (LOF) and gain-of-function (GOF) alleles, respectively. Although the pharmacogenetic-guided approach to the selection of antiplatelet therapy appears promising in ACS, studies have shown conflicting results, and direct randomized evidence linking this approach with the better outcomes is lacking. CONCLUSIONS: Genotype-guided selection of antiplatelet therapy is expected to be useful in patients undergoing percutaneous coronary intervention (PCI) with a high risk of adverse outcomes. The patient-physician discussion should be an essential part of this decision-making process. Large-scale multicenter randomized controlled trials using the point-of-care genotype assay are needed to investigate this approach further before its use can be recommended in all comers.

Combined Neprilysin and RAS Inhibition in Cardiovascular Diseases: A Review of Clinical Studies.

The aim of this comprehensive review article is to emphasize on the possible exploration of a new therapeutic approach in the management of heart failure (HF) and other cardiovascular diseases: the renin-angiotensin-aldosterone system-neprilysin combination inhibitors, also called angiotensin receptor neprilysin inhibitor, valsartan/sacubitril (LCZ696). Sacubitril is an inhibitor of neutral endopeptidase (NEP) which degrades vasoactive peptides such as atrial natriuretic peptide and brain natriuretic peptide. Valsartan is an angiotensin receptor blocker which is usually used in hypertension. Although HF has been a global health burden, for decades there has been lack of novel therapeutic options as many trials failed due to potential side effects. With the published results of the landmark trial Prospective comparison of ARNI with ACEI to Determine the Impact on Global Mortality and morbidity in HF (PARADIGM-HF), a new direction in the treatment of HF is anticipated. This trial showed that LCZ696 was able to reduce the primary composite end point of cardiovascular death or HF hospitalization, and similar reduction was observed for cardiovascular death. This review article also highlights the results of 4 published trials of LCZ696 in both HTN and HF. After the results of PARADIGM-HF trial, the major challenge will be outcome in regular clinical practice, as subjects in the trial were mostly stable New York Heart Association class II patients with no comorbidities. In addition, many trials are simultaneously in progress regarding the use of LCZ696 in patients with diabetes, renal failure, and hepatic impairment. To conclude, sacubitril/valsartan significantly improved morbidity and mortality in patients with chronic HF, but it will need meticulous attention when used in real outpatient practice.

The Emerging Role of FDG PET/CT in Diagnosing Endocarditis and Cardiac Device Infection.

Infective endocarditis and cardiac implantable electronic device infection (CIEDI) have witnessed an increasing incidence in clinical practice and associated with increasing health care expenditure. Expanding indications of CIED in various cardiovascular conditions have also contributed to the surge of these infections. Early diagnosis of these infections is associated with a favorable prognosis. Given the lack of a single definitive diagnostic method and the limitations of echocardiography, which is considered a central diagnostic imaging modality, additional imaging modalities are required. Recent studies have highlighted the diagnostic utility of FDG PET and CT. In this review article, we discuss the existing limitations of echocardiography, acquisition protocols of PET/CT, and indications of these advanced imaging modalities in infective endocarditis and CIEDI diagnosis.

Bempedoic acid and its role in contemporary management of hyperlipidemia in atherosclerosis.

Atherosclerotic heart disease is the leading cause of mortality and morbidity in the USA. Low density lipoprotein (LDL) has been the target for many hypolipidemic agents to modify atherosclerotic risk. Bempedoic acid is a novel hypolipidemic drug that inhibits the enzymatic activity of ATP citrate lyase in the cholesterol synthesis pathway. CLEAR Harmony, CLEAR Wisdom, CLEAR Tranquillity and CLEAR Serenity have shown safety and efficacy associated with long term administration of this drug. Studies have shown effectiveness in reducing LDL-C in both statin intolerant patients and in patients on maximally tolerated doses of statin. The fixed drug combination of bempedoic acid and ezetimibe in a recent phase III showed significant reduction in LDL compared with placebo, which might be a promising future for LDL reduction among statin intolerant patients. Bempedoic acid also reduced inflammatory markers like hs-CRP. Given these results, bempedoic acid alone and in combination with ezetimibe received the USA FDA approval for adults with heterozygous familial hypercholesterolaemia or established atherosclerotic cardiovascular disease. We present a comprehensive review exploring the underlying mechanism, pre-clinical studies, and clinical trials of bempedoic acid and discuss the potential future role of the drug in treating hyperlipidaemia.

A Brief Overview of Recurrent Pericarditis Management and the Potential of Rilonacept as a New Therapeutic Option.

Recurrent pericarditis affects 15-30% of patients after acute pericarditis. A large number of the patients with recurrent pericarditis can become corticosteroid dependent, leading to disease chronicity and drug dependence, with additional morbidity from long-term steroid use. Recent randomized trials indicate the efficacy of the interleukin-1 inhibitors anakinra and rilonacept in recurrent pericarditis, including colchicine-resistant and corticosteroid-dependent cases. In particular, rilonacept was assessed in the RHAPSODY clinical trial and found to be a potential treatment option that would decrease recurrent episodes, enabling patients to be weaned off steroids. Additionally, new data indicate that rilonacept should be considered as an option for patients with recurrent pericarditis, as add-on therapy to colchicine and nonsteroidal anti-inflammatory drugs, in place of steroids. We review the current management options for recurrent pericarditis as well as rilonacept as a prospective new addition to our armamentarium.

The Role of Dapagliflozin in the Management of Heart Failure: An Update on the Emerging Evidence.

The burden and cost of heart failure management, primarily in the form of hospitalization in the setting of decompensated heart failure, continue to be some of the biggest clinical challenges in cardiovascular medicine. In recently published randomized controlled trials, including DAPA-HF, sodium-glucose cotransporter 2 (SGLT2) inhibitor dapagliflozin was shown to reduce hospitalization from heart failure or mortality associated with cardiovascular causes, when added to existing guideline-directed medical therapy. The American College of Cardiology (ACC) released a Clinical Pathway guideline that recommends the use of dapagliflozin in clinical management of heart failure, with or without diabetes. Furthermore, the results of the DAPA-CKD trial broaden the utility of dapagliflozin as a therapeutic option in patients with advanced kidney disease. In this article, the authors explore the existing evidence on dapagliflozin in heart failure with reduced ejection fraction and highlight the need for further research on uses of dapagliflozin in the world of heart failure.

Does Insurance Effect the Outcome in Patients With Acute Coronary Syndrome?: An Insight from the Most Recent National Inpatient Sample.

Several studies have shown disparities in outcome in the patients with Acute coronary syndrome (ACS) based on several factors. Treatment might differ based on insurance type. Therefore, we retrospectively analyzed National Inpatient Sample (NIS 2016) data to identify the impact of different types of insurances on mortality outcome in patients admitted with ACS. ICD-CM-10 codes were used to identify hospital discharges with a principal diagnosis of ACS. Observations were stratified based on insurance (Medicare, Medicaid, Private, and No insurance). Primary and secondary outcomes were in-hospital mortality, length of stay and total cost. Any potential confounders were adjusted using multivariate logistic regression. STATA/IC 15.1 Stata Corp LLC was used for analysis. A total of 8,01,195 hospitalizations with the primary diagnosis of ACS were identified, of which 59.2% had Medicare, 9.72% had Medicaid, 26.8% had Private insurance, and 4.3% had no insurance. Higher odds of mortality were seen in the patients with Medicare, Medicaid, and Noninsured group. Adjusted Odds ratio for mortality in Medicare was 1.01 (confidence interval [CI]: 0.94-1.1; P = 0.65), in Medicaid was 1.16 (CI: 1.03-1.30; P = 0.01) and in uninsured group was 1.46 (CI: 1.26-1.69; P ≤ 0.01). However, the patients with private insurance adjusted odds ratio for mortality were 0.77 (CI: 0.70-0.84; P ≤ 0.01) compared to the patients with other insurance groups. Above results show that the disparity exists in the outcome of patients admitted with ACS based on their insurance types, particularly for Medicaid patients. We need further studies to understand the root cause of this disparity.

Serum Bilirubin and Coronary Artery Disease: Intricate Relationship, Pathophysiology, and Recent Evidence.

Coronary artery disease (CAD) is a major cause of morbidity, mortality, and healthcare expenditure. A number of environmental and genetic risk factors have been known to contribute to CAD. More recently, a number of studies have supported as well as opposed a possible protective benefit of bilirubin in CAD, since it has anti-inflammatory, antioxidant, and antiaggregatory properties that may reduce atherogenesis. It also shares associations with different forms of CAD, namely stable CAD, unstable angina pectoris, stable angina pectoris, and acute myocardial infarction. Lack of sufficient evidence, however, has failed to elucidate a causal relationship between serum bilirubin level and risk of CAD. Therefore, in this update, we attempted to simplify this intricate relationship between bilirubin and CAD, revisit the pathophysiology of disease, how bilirubin may be protective, and to summarize the findings of the current literature.

Anticoagulation in Pulmonary Arterial Hypertension: Do We Know the Answer?

The shear stress and hypoxia in the pulmonary artery in patients with pulmonary arterial hypertension(PAH) causes endothelial dysfunction, smooth muscle proliferation and activation of thrombotic pathways leading to in situ thrombosis. Targeting the thrombotic pathways is a proposed mechanism to slow disease progression and improve survival. Over the years, the survival in patients with PAH has improved due to multiple factors with the increased use of anticoagulation as one of them. Both European Respiratory Society/European Society of Cardiology and American College of Cardiology/American Heart Association guidelines make grade II recommendations for using anticoagulation in PAH. The guidelines are based on weak observational studies with high risk of bias which have only studied warfarin as the choice of anticoagulation. In this article, we review the pathophysiology, rationale and the current literature investigating the role of anticoagulation in PAH.

Aspirin for Primary Prevention of Coronary Artery Disease.

Primary prevention of coronary artery disease (CAD) is an important means to reduce the burden of the disease. Aspirin has been widely prescribed over the last several decades as part of primary CAD prevention strategy. However, 3 recent hallmark trials - ARRIVE, ASCEND and ASPREE have raised serious questions about this common practice. Although, aspirin reduced incidence of non-fatal MI and stroke in these recent studies, bleeding risk was higher. In the present era, where regular exercise, healthy diet, smoking cessation, and statins are used to manage the risk factors of CAD, additional prescription of aspirin seems more harmful than beneficial. The guidelines of major societies such as European Society of Cardiology (ESC), American College of Cardiology (ACC), and American Heart Association (AHA) also reflect this shift. In this article, the authors aim to highlight the current evidence on aspirin use for primary prevention of CAD, in the context of evolving contrasting clinical trial data from the last 2 decades. We also highlight the pertinent sections of the most recent clinical guidelines of European Society of Cardiology, American College of Cardiology, and American Heart Association in this article.

Trends of Cardiac Complications in Patients With Rheumatoid Arthritis: Analysis of the United States National Inpatient Sample; 2005-2014.

BACKGROUND: Rheumatoid arthritis (RA) is a chronic inflammatory condition. Chronic inflammation is associated with atherosclerosis, hypertension, diabetes, chronic obstructive pulmonary disease (COPD), chronic kidney disease. But sparse data are available regarding the trends of cardiovascular diseases and complications in RA. We conducted a National Inpatient Sample database analysis to demonstrate the trends of cardiac complications in patients with RA. METHODS: We used National Inpatient Sample data from 2005 to 2014 to identify admissions with the diagnosis of RA and identified who had associated cardiovascular complications also. The International Classification of Diseases-9th Revision-Clinical Modification codes were used for the diagnoses of RA; congestive heart failure (CHF), acute myocardial infarction (AMI), and atrial fibrillation (AF). RESULTS: A statistically significant increasing trend of AMI, CHF, and AF was found. Independent predictors of mortality in RA patients with AMI were age (OR 1.03, CI 1.02-1.04; P < 0.001), COPD (OR 1.67, CI 1.40-2.00; P < 0.001), cerebrovascular disease (OR 2.207, CI 1.71-2.86; P < 0.001), renal disease (OR 1.42, CI 1.16-1.75; P = 0.001), and alcohol abuse (OR 2.73, CI 1.73-4.32; P < 0.001). Independent predictors of mortality in RA patients with CHF were age (odds ratio [OR] 1.02, confidence interval [CI] 1.017-1.024; P < 0.001]), COPD (OR 1.09, CI 1.01-1.18; P = 0.023), cerebrovascular disease (OR 1.67, CI 1.44-1.95; P < 0.001), renal disease (OR 1.16, CI 1.07-1.27; P = 0.001). Independent predictors of mortality in RA patients with AF were age (OR 1.02, CI 1.02-1.03; P < 0.001), race (OR 1.16, CI 1.02-1.31; P = 0.022), COPD (OR 1.56, CI 1.42-1.71; P < 0.001), peripheral arterial disease (OR 1.34, CI 1.16-1.53; P < 0.001), cerebrovascular disease (OR 2.27, CI 1.0-2.58; P < 0.001), renal disease (OR 1.60, CI 1.44-1.80; P < 0.001). The mortality trend has increased significantly in the CHF (P = 0.025) and AF (P = 0.042) groups during this study period. CONCLUSIONS: We have found a significant increase in trend of cardiovascular complications in RA patients. The proportion of patients, with cardiovascular comorbidities, have also been increased significantly.

Sex Differences in In-Hospital Outcomes of Transcatheter Aortic Valve Replacement.

Since the introduction of transcatheter aortic valve replacement (TAVR), there has been a paradigm shift in the management of severe aortic stenosis. While women represent almost half of the patients undergoing TAVR, there are limited data on sex-based comparisons in hospital outcomes and predictors of mortality in women and men. The National Inpatient Sample database from 2012 to 2015 was used to identify TAVR using international classification of diseases-9 clinical modification procedure codes 35.05 and 35.06. We identified 61,239 patients who underwent TAVR between 2012 and 2015. After adjusting for potential confounders, women had higher odds of all-cause mortality as compared to men [odds ratio (OR) 1.25, 95% confidence interval (CI): 1.01-1.54; P = 0.036]. Moreover, women had significantly increased odds of cardiac complications [OR 2.41, 95% CI: 1.67-3.49; P ≤ 0.01], respiratory complications [OR 1.20 95% CI: 1.07-1.34; P = 0.001], major hemorrhage requiring transfusion [OR 1.51, 95% CI: 1.37-1.67; P ≤ 0.001], neurological complications [OR 1.38, 95% CI: 0.95-1.99; P = 0.08], need for vasopressor treatment [OR 1.33, 95% CI: 1.01-1.75; P = 0.04], and vascular complications [OR 1.73, 95% CI: 1.19-2.52; P = 0.004]. On the contrary, the odds of pacemaker requirement [OR 0.85, 95% CI: 0.75-0.97; P = 0.02], and acute kidney injury [OR 0.80, 95% CI: 0.71-0.91; P = 0.001] were significantly lower in women. Among patients undergoing TAVR, women were more likely to have in-hospital complications and mortality as compared with men. Further studies are needed to identify the discrepancy in in-hospital outcomes with sex-specific factors being considered.

Acute myocardial infarction in the young with diabetes mellitus- national inpatient sample study with sex-based difference in outcomes.

BACKGROUND: Mortality after AMI is on the decreasing trend; however, this favorable trend is not observed in the young, especially women. Therefore, we conducted a retrospective analysis using the Nationwide Inpatient Sample (NIS) to identify sex-based outcomes following AMI in young with diabetes. METHODS: NIS 2010-2014 was used to identify all patients with AMI using the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes. Men (N = 30,950) and women (N = 17,928) patients diagnosed with diabetes were identified and stratified as young if age >18 and <45 years. RESULTS: Young women with AMI and concomitant diabetes having a higher burden of overall traditional and non-traditional comorbidities. NSTEMI was the major presentation in women as compared to men. Young women with AMI and concomitant diabetes were less likely to receive revascularization with PCI [51.1% vs. 58.2%; OR 0.86, CI 0.78-0.94] or CABG [7.9% vs. 10.1%; OR 0.64, CI 0.54-0.75]. Adjusted all-cause in-hospital mortality did not differ significantly between the two groups [OR 1.06, CI 0.74-1.52]. Women had lower odds of developing cardiogenic shock, ventricular arrhythmias, and AKI, and were more likely to develop major bleeding requiring transfusion, and mitral regurgitation. CONCLUSION: There were significant differences between young men and women with diabetes in terms of baseline characteristics and clinical presentation, use of revascularization, and cardiac complications, yet overall, in-hospital mortality does not appear to differ. More studies are needed to identify the interaction of sex and diabetes in young AMI population, and areas for practice improvement.

Cost of inpatient heart failure care and 30-day readmissions in the United States.

BACKGROUND: Heart failure hospitalizations are a major financial cost to healthcare systems. This study aimed to evaluate the costs associated with inpatient hospitalization. METHODS: Patients with a primary diagnosis of heart failure during a hospital admission between 2010 and 2014 in the U.S. Nationwide Readmission Database were included. The primary outcome was total cost defined by direct cost of index admission and first readmission within 30-days. RESULTS: A total of 2,645,336 patients with primary heart failure were included in the analysis. The mean ± SD total cost overall was $13,807 ± 24,145; with mean total costs of $15,618 ± 25,264 for patients with 30-day readmission and $11,845 ± 22,710 for patients without a readmission. The comorbidities strongly associated with increased cost were pulmonary circulatory disorder (OR 26.24 95% CI 20.06-34.33), valvular heart disease (OR 25.42 95% CI 20.65-31.28) and bleeding (OR 5.96 95% CI 5.47-6.50). Among hospitalized patients, 12.6% underwent an invasive diagnostic procedure or treatment. The mean cost for patients without invasive care was $10,995. This increased by $129,547, $119,769, $251,110 and $293,575 for receipt of circulatory support, intra-aortic balloon pump, LV assist device and heart transplant. The greatest mean additional cost annually was associated with receipt of coronary angiogram ($26,282 per person for a total of ($728.5 million) and mechanical ventilation ($54,529 per person for a total of $501.7 million). CONCLUSION: In conclusion, the costs associated with inpatient heart failure care are significant, and the major contributors to inpatient costs are comorbidities, invasive procedures and readmissions.

Gout Pharmacotherapy in Cardiovascular Diseases: A Review of Utility and Outcomes.

Hyperuricemia and gout have been linked to an increased risk for cardiovascular (CV) disease, stroke, hypertension, heart failure, and chronic kidney disease, possibly through a proinflammatory milieu. However, not all the drugs used in gout treatment improve CV outcomes; colchicine has shown improved CV outcomes in patients with recent myocardial infarction and stable coronary artery disease independent of lipid-lowering effects. There is resurging interest in colchicine following publication of the COLCOT, LoDoCo, LoDoCo2, LoDoCo-MI trials, and COLCORONA trial which will shed light on its utility in COVID-19. Our aim is to review the CV use of colchicine beyond pericardial diseases, as well as CV outcomes of the available gout therapies, including allopurinol and febuxostat. The CARES trial and its surrounding controversies, which lead to the US FDA 'black box' warning on febuxostat, in addition to the recent FAST trial which contradicts this and finds febuxostat to be non-inferior, are discussed in this paper.

Impact of pre-existent vascular and poly-vascular disease on acute myocardial infarction management and outcomes: An analysis of 2 million patients from the National Inpatient Sample.

BACKGROUND: Patients with pre-existing vascular disease are known to have worse outcomes after acute myocardial infarction (AMI). However, there is limited data for outcomes stratified by type and number of vascular territories involved. METHODS: Using the Nationwide Inpatient Sample (2015-2017), we examined outcomes of AMI in patients with pre-existent vascular disease stratified by number as well as types of diseased beds including all five major vascular sites: cardiac, cerebrovascular, renal, aortic and peripheral vascular disease (PVD). Multivariable logistic regression was used to determine the adjusted odds ratios (aOR) of adverse outcomes and invasive procedure utilization. RESULTS: Out of 2,184,614 AMI admissions, 49.7% had pre-existent vascular disease. The odds of major adverse cardiovascular and cerebrovascular events (MACCE), mortality, ischemic stroke and major bleeding incrementally increased and was highest in those with ≥3 vascular sites involved (aOR for MACCE 1.16, CI 1.13-1.19; mortality 1.3, CI 1.26-1.34; stroke 1.15, CI 1.1-1.2; major bleeding 1.21, CI 1.16-1.25). Amongst those with a single pre-existent diseased vascular bed, the adjusted odds of MACCE appeared to be higher in those with PVD (1.28, CI 1.26-1.31), aortic disease (1.24, CI 1.19-1.29), and cerebrovascular disease (1.22, CI 1.2-1.25). Patients with pre-existent vascular disease had a lower overall likelihood of undergoing invasive revascularization procedures. CONCLUSIONS: Approximately half of the population presenting with AMI have pre-existent vascular disease. There is an incremental increase in adverse outcomes with increasing number of diseased vascular beds, with further differences in outcomes and utilization of invasive procedures based on sub-types of sites involved.

Impact of Pulmonary Hypertension on In-Hospital Outcomes and 30-Day Readmissions Following Percutaneous Coronary Interventions.

OBJECTIVE: To evaluate the impact of pulmonary hypertension (PH) on percutaneous coronary intervention (PCI) outcomes and 30-day all-cause readmissions by analyzing a national database. METHODS: We queried the 2014 National Readmissions Database to identify patients undergoing PCI using International Classification of Diseases, Ninth Revision, Clinical Modification codes. These patients were then subcategorized based on the coded presence or absence of PH and further analyzed to determine the impact of PH on clinical outcomes, health care use, and 30-day readmissions. RESULTS: Among 599,490 patients hospitalized for a PCI in 2014, 19,348 (3.2%) had concomitant PH. At baseline, these patients were older with a higher burden of comorbidities. Patients with PH had longer initial hospitalizations and higher 30-day readmission rates and mortality than their non-PH counterparts. This was largely driven by cardiac causes, most commonly heart failure (20.3% vs 9.0%, P<.001) and non-ST-segment elevation myocardial infarction. Recurrent coronary events (17.5% vs 9.5%, P<.05) including ST-segment elevation myocardial infarction predominated in the non-PH group. CONCLUSION: Patients with PH undergoing PCI are a high-risk group in terms of mortality and 30-day readmission rates. Percutaneous coronary intervention in patients with PH is associated with higher rates of recurrent heart failure and non-ST-segment elevation myocardial infarction, rather than recurrent coronary events or ST-segment elevation myocardial infarction. This perhaps indicates a predominance of demand ischemia and heart failure syndromes rather than overt atherothrombosis in the etiology of chest pain in these patients.

Defining the Role of Icosapent Ethyl in Clinical Practice.

The health benefit of fish oil, i.e. omega-3 fatty acids (ω-3 FA) has a long history of debate. While there are a number of medications to reduce serum triglyceride levels, none have shown unanimous cardiovascular (CV) benefits. The most recent Reduction of Cardiovascular Events with Icosapent Ethyl-Intervention Trial (REDUCE-IT) assessing the CV outcome of one highly purified prescription ω-3 FA has certainly rejuvenated the debate. While this trial has been regarded as one of the most important landmark trials in preventive cardiology, the tolerability issue in a very high dose (4 g/day, as administered in the trial) is still a matter of concern. This article summarizes the current status and future perspective of icosapent ethyl in clinical practice in light of REDUCE-IT.

In-hospital clinical outcomes of transcatheter aortic valve replacement in patients with concomitant carotid artery stenosis: Insights from the national inpatient sample.

BACKGROUND: Carotid artery stenosis (CAS) is a common occurrence in elderly patients undergoing transcatheter aortic valve replacement (TAVR). We conducted a retrospective study to identify the impact of CAS on in-hospital outcomes following TAVR. METHODS: We queried the National Inpatient Sample (NIS) for 2016-2017 and identified patients who underwent TAVR with concomitant CAS using the ICD-10 codes. The primary endpoint of our study was in-hospital mortality and acute ischemic stroke. RESULTS: We identified 80,740 TAVR-related hospitalizations. Of these, 6.9% (N = 5555) patients had concomitant CAS. The mean age for CAS patients was 80 ± 7.4 years. Females were represented equally in both groups. Traditional comorbidities like dyslipidemia [78.3% (N = 4350) vs. 68.2% (N = 51261); P < 0.001] and peripheral arterial disease [27.4% (N = 1525) vs. 12.7% (N = 9526); P < 0.001] were more frequently observed among CAS patients. Patients with CAS had higher rates of previous stroke [17.5% (N = 970) vs. 11.8% (N = 8902); P < 0.001] and CABG 23.8% (N = 1320) vs. 18.6% (N = 14022); P < 0.001]. Other cardiovascular risk factors were similar between the two groups. Moreover, no differences in in-hospital outcomes including mortality [odds ratio (OR): 1.35, CI: 0.48-3.83; P = 0.57] were observed in the propensity matched cohort. CONCLUSIONS: Our study did not find any major differences in outcomes in the CAS group following TAVR; however, a more detailed randomized controlled study with long-term follow-up of these patients is needed.
