RESUMO
OBJECTIVE: We sought to examine outcomes of ultrafiltration in real world community-based hospital settings. BACKGROUND: Ultrafiltration (UF) is an accepted therapeutic option for advanced decompensated heart failure (ADHF). the feasibility of UF in a community hospital setting, by general cardiologists in a start-up program had not been objectively evaluated. METHODS: We retrospectively analyzed the first-year cohort of ADHF patients treated with UF from 10/1/2019 to 10/1/2020, which totaled 30 patients, utilizing the CHF Solutions Aquadex FlexFlow™ System with active UF rate titration. RESULTS: Baseline patient characteristics were similar to RCTs: mean age 63, 73 % male; 27 % female; 53 % Caucasian; 47 % African American; 77 % had LVEF ≤ 40. The baseline mean serum creatinine (Cr) was 1.84 ±0.62 mg/dL, mean GFR of 36.95 ±9.60 ml/min. HF re-admission rates were not significantly different than prior studies (17.2 % at 30 d, 23.3 % at 60 d, but in our cohort, per patient HF re-admission rates were reduced significantly by 60 d (0.30 p = 0.017). CONCLUSION: Our analysis showed success with UF in mainstream setting with reproducible results of significant volume loss without adverse renal effect, mitigation of recurrent Hdmissions, and remarkable subjective clinical benefit.
RESUMO
The left atrial appendage (LAA) is often thought of as a vestigial organ serving as a nidus for clot formation in those with atrial fibrillation (A-fib). The LAA, however, has unique anatomy which allows it to serve special functions in the human body. Closing the LAA has been shown to decrease the risk of thromboembolic events in patients who cannot tolerate anticoagulation. Several methods of closure exist including percutaneous endocardial closure, epicardial closure, and surgical clipping. In addition to decreasing stroke risk, there appears to be physiologic changes that occur after LAA closure. This comprehensive review aims to describe the functions of the LAA, compare the different methods of closure, and propose a new method for identifying which patients may benefit from LAA closure versus anticoagulation based on each patients' individual comorbidities rather than their contraindications.

Pulmonary endarterectomy (PEA) is the first-line treatment for patients with chronic thromboembolic pulmonary hypertension (CTEPH). However, some patients with CTEPH are considered inoperable, and in the last decade, balloon pulmonary angioplasty (BPA) has emerged as a viable therapeutic option for these patients with prohibitive surgical risk or recurrent pulmonary hypertension following PEA. Numerous international centers have increased their procedural volume of BPA and have reported improvements in pulmonary hemodynamics, patient functional class and right ventricular function. Randomized controlled trials have also demonstrated similar findings. Recent refinements in procedural technique, increased operator experience and advancements in procedural technology have facilitated marked reduction in the risk of complications following BPA. Current guidelines recommend BPA for patients with inoperable CTEPH and persistent pulmonary hypertension following PEA. The pulmonary arterial endothelium plays a vital role in the pathophysiologic development and progression of CTEPH.

BACKGROUND: The use of traditional models to predict heart failure (HF) has limitations in preventing HF hospitalizations. Artificial intelligence (AI) and machine learning (ML) in cardiovascular medicine only have limited data published regarding HF populations, with none assessing the favorability of decongestive therapy aquapheresis (AQ). AI and ML can be leveraged to design non-traditional models to identify those who are at high risk of HF readmissions. OBJECTIVES: This study aimed to develop a model for pretreatment identification of risk for 90-day HF events among HF patients who have undergone AQ. METHODS: Using data from the AVOID-HF (Aquapheresis versus Intravenous Diuretics and Hospitalization for Heart Failure) trial, we designed a ML-based predictive model that can be used before initiating AQ to anticipate who will respond well to AQ and who will be at high risk of future HF events. RESULTS: Using ML we identified the top ten predictors for 90-day HF events. Interestingly, the variable for 'intimate relationships with loved ones' strongly predicted response to therapy. This ML-model was more successful in predicting the outcome in HF patients who were treated with AQ. In the original AVOID-HF trial, the overall 90-day HF event rate in the AQ arm was 32%. Our proposed predictive model was accurate in anticipating 90-day HF events with better statistical accuracy (area under curve 0.88, sensitivity 80%, specificity 75%, negative predictive value 90%, and positive predictive value 57%). CONCLUSIONS: ML can help identify HF patients who will respond to AQ therapy. Our model can identify super-respondents to AQ therapy and predict 90-day HF events better than currently existing traditional models. CONDENSED ABSTRACT: Utilizing data from the AVOID-HF trial, we designed a ML-predictive model that can be used before initiating AQ to anticipate who will respond well to AQ and who will be at high risk of future HF events. Using ML, we identified the top 10 predictors for 90-day HF events. Our model can identify super-respondents to ultrafiltration therapy and predict 90-day HF events better than currently existing traditional models.

In recent years, there has been a notable and concerning rise in the prevalence of mental disorders, indicating a growing societal challenge that warrants attention and support for affected individuals. Psychiatric problems range on a wide spectrum from as little as work or school related stress to as big as severe depression related to the loss of a loved one, a sense of loneliness, etc. This current generation yields the highest amounts of mental disorder patients due to the newfound pressures, difficulties, and ways of life. According to the Center for Disease Control and Prevention, more than 1 in 5 US adults live with a mental illness and about 1 in 25 US adults live or lived with a serious mental illness such as schizophrenia, bipolar disorder, or major depression. A similar statistic shows us that about 695,000 people in the United States in 2021 died due to some form of heart related disease. That is 1 in every 5 deaths. More recently, it has been noticed that these psychiatric disorders and heart diseases could be correlated. In this manuscript, we review the current literature on the effect and correlation of psychiatric disorders on the cardiovascular system. We present a review on primarily the "5 major psychiatric disorders," according to the NIH: depression, autism, attention-deficit/hyperactivity disorder, bipolar disorder, and schizophrenia. We will also present a review on stress-induced cardiac diseases, especially more recently with the rise of the COVID-19 Pandemic.

Background: Long QT syndrome type 2 (LQT2) is caused by mutations in the KCNH2/human ether-à-go-go-related gene (hERG). Some hERG genetic mutation-associated diseases are alleviated by hERG-specific drug chaperones (glycerol, dimethyl sulfoxide, trimethylamine N-oxide, thapsigargin), delayed rectifier K+ current (IKr) blockers methanesulfonanilide E4031, the antihistamine astemizole, or the prokinetic drug cisapride, and the anti-arrhythmic drug quinidine. Meanwhile, many in vivo and in vitro studies have reported the efficacy of 4-phenylbutyric acid (4-PBA) in diseases with inherited genetic mutations. This study aims to explore potential therapeutic agents for hERG/G572R mutated ion channel. Methods: pcDNA3/hERG [wild type (WT)]-FLAG and pcDNA3/hERG (G572R)-FLAG plasmids were transfected into HEK293 cells. A western blot (WB) experiment was conducted to analyze protein expression. Quantitative real-time polymerase chain reaction (qPCR) was used to analyze the messenger RNA (mRNA) expression levels in the WT/G572R heterozygous HEK293 cell model treated with or without 4-PBA. The interaction between WT/G572R and BIP (GRP78), GRP94, and 3-hydroxy-3-methylglutaryl coenzyme A reductase degradation protein 1 (HRD1) was tested by co-immunoprecipitation (co-IP). To investigate the effect of 4-PBA on the WT/G572R channel current, we used electrophysiological assays (patch-clamp electrophysiological recordings). Results: The results showed that WT/G572R activated the ATF6 pathway in the endoplasmic reticulum stress (ERS), the ERS response markers GRP78, GRP94, and calreticulin (CRT)/calnexin (CNX), and HRD1, which decreased after application of the ERS inhibitor 4-PBA. The results of co-IP confirmed that the ability of hERG interacted with GRP78, GRP94, and HRD1. Moreover, 4-PBA increased the current of WT/G572R and reversed the gating kinetics of the WT/G572R channel. Conclusions: 4-PBA corrects hERG channel transport defects by inhibiting excessive ERS and the endoplasmic reticulum-associated degradation (ERAD)-related gene E3 ubiquitin ligase HRD1. Additionally, 4-PBA improved WT/G572R channel current. 4-PBA is expected to be developed as a new treatment method for LQT2.
RESUMO
Cardiac tamponade is a serious clinical syndrome that often presents with the classic triad of hypotension, jugular vein distention and diminished or muffled heart sounds on auscultation (Beck's Triad). This phenomenon occurs due to fluid accumulation in the pericardial space which compresses the heart, reduces cardiac output and may cause cardiogenic shock. In this report, we present a case of a 22-year-old female with a congenital atrial septal defect (ASD) and right ventricular failure with tamponade physiology with an associated viral illness.
RESUMO
Left ventricular pseudoaneurysm is a well-known complication of myocardial infarction and open-heart surgery and has recently been described as succeeding transapical transcatheter aortic valve replacement. While surgical intervention is the conventional therapeutic approach, transcatheter closure can be considered in patients at high risk for surgical procedures. In this article, we present a postmyocardial infarction pseudoaneurysm for which closure was done via retrograde left ventricular access using an Amplatzer Septal Occluder, and provide a review of recent literature focusing on indications and outcomes of the different percutaneous techniques and devices.

The practice of fasting before elective cardiac procedures including cardiac catheterization and transesophageal echocardiography is commonly implemented but evidence for these requirements is lacking. Fasting periods often exceed the intended length of time, increasing the risk of irritability, dehydration, acute kidney injury, hypoglycemia, and length of hospitalization. The practice of perioperative fasting relies on the premise that aspiration during general anesthesia can be mitigated by minimizing the volume of gastric contents, and stomach acidity. But the evidence has shown that fasting does not guarantee an empty stomach, and there is no observed association between aspiration and compliance with common fasting guidelines. Elective cardiac procedures are performed using procedural sedation, where the risk of serious aspiration is small. In most patients, we argue, that strict fasting requirements should be reduced, and a more nuanced fasting protocol based on individual patient characteristics and risk factors should be utilized given the overall low risk of aspiration with elective procedures utilizing procedural sedation. In this review, we examine the historical origins and current evidence relating to the practice of fasting as it relates to cardiac catheterization and transesophageal echocardiography.

Amyloidosis is a group of disorders that can affect almost any organ due to the misfolding of proteins with their subsequent deposition in various tissues, leading to various disease manifestations based on the location. When the heart is involved, amyloidosis can manifest with a multitude of presentations such as heart failure, arrhythmias, orthostatic hypotension, syncope, and pre-syncope. Diagnosis of cardiac amyloidosis can be difficult due to the non-specific nature of symptoms and the relative rarity of the disease. Amyloidosis can remain undiagnosed for years, leading to its high morbidity and mortality due to this delay in diagnosis. Newer imaging modalities, such as cardiac magnetic resonance imaging, advanced echocardiography, and biomarkers, make a timely cardiac amyloidosis diagnosis more feasible. Many treatment options are available, which have provided new hope for this patient population. This manuscript will review the pathology, diagnosis, and treatment options available for cardiac amyloidosis and provide a comprehensive overview of this complicated disease process.

With recent advancements in imaging modalities and techniques and increased recognition of the long-term impact of several structural heart disease interventions, the number of procedures has significantly increased. With the increase in procedures, also comes an increase in cost. In view of this, efficient and cost-effective methods to facilitate and manage structural heart disease interventions are a necessity. Same-day discharge (SDD) after invasive cardiac procedures improves resource utilization and patient satisfaction. SDD in appropriately selected patients has become the standard of care for some invasive cardiac procedures such as percutaneous coronary interventions. This is not the case for the majority of structural heart procedures. With the coronavirus disease 2019 pandemic, safely reducing the duration of time spent within the hospital to prevent unnecessary exposure to pathogens has become a priority. In light of this, it is prudent to assess the feasibility of SDD in several structural heart procedures. In this review we highlight the feasibility of SDD in a carefully selected population, by reviewing and summarizing studies on SDD among patients undergoing left atrial appendage occlusion, patent foramen ovale/atrial septal defect closure, Mitra-clip, and trans-catheter aortic valve replacement procedures.
RESUMO
The clinical choice between rate or rhythm control therapies has been debated over the years. In 2002, the AFFIRM trial demonstrated that the rhythm-control strategy had no survival advantage over the rate-control strategy. Eighteen years later, EAST-AFNET 4 showed that the rhythm-control approach is better than rate control in reducing adverse cardiovascular outcomes in patients with a recent diagnosis of atrial fibrillation (AF). During the time between AFFIRM and EAST-AFNET 4, rhythm control understanding, specifically ablation, improved, while rate-control strategies remained the same possibly leading to the change in results seen in EAST-AFNET 4. This review seeks to evaluate the rate- and rhythm-control strategies, focusing on the important clinical trials in the past two decades. These trials have shown great advancement in AF management; however, the search for the best approach to controlling AF and minimizing the burden of symptoms is still a work in progress and needs further research.

Cardiovascular diseases are the most common cause of death worldwide, with cardiovascular medications being amongst the most common medications prescribed. These medications have diverse effects on the heart, vascular system, as well as other tissues and organ systems. The extra cardiovascular effects have been found to be of use in the treatment of non-cardiovascular diseases and pathologies. Minoxidil is used to manage systemic hypertension with its well-known side effect of hirsutism used to treat alopecia and baldness. Sildenafil was originally investigated as a treatment option for systemic hypertension; however, its side effect of penile erection led to it being widely used for erectile dysfunction. Alpha-1 blockers such as terazosin are indicated to treat systemic hypertension but are more commonly used for benign prostatic hyperplasia and post-traumatic stress disorder. Beta blockers are the mainstay treatment for congestive heart failure and systemic hypertension but have been found useful to help in patients with intention tremors as well as prophylaxis of migraines. Similarly, calcium channel blockers are indicated in medical expulsion therapy for ureteric calculi in addition to their cardiovascular indications. Thiazides are commonly used for treating systemic hypertension and as diuretics. Thiazides can cause hypocalciuria and hypercalcemia. This side effect has led to thiazides being used to treat idiopathic hypercalciuria and associated nephrolithiasis. Spironolactone is commonly utilized in treating heart failure and as a diuretic for edema. It's well described anti-androgen side effects have been used for acne vulgaris and hirsutism in polycystic ovarian syndrome. This review article discusses how the various extracardiovascular effects of commonly used cardiovascular medications are put to use in managing non-cardiovascular conditions.

Sudden cardiac death is a major cause of cardiovascular mortality in the United States with 250,000-450,000 deaths annually. Transvenous Implantable Cardioverter-Defibrillator (ICD) has been conventionally used for both primary and secondary prevention of ventricular tachycardia or fibrillation (VT/VF). It is also associated with a high risk of complications like hemothorax, pneumothorax, cardiac tamponade, lead failure, and increased risk for infections. Subcutaneous ICD (S-ICD) poses as a viable alternative with reduced chances of complications. This manuscript aims to review S-ICD as an alternative to conventional transvenous ICD and its efficacy. We conducted a Medline search of "Subcutaneous," "ICD," "transvenous," and "ventricular tachycardia or fibrillation (VT/VF)" to identify pivotal trials published before June 2021, for inclusion in this review. Major practice guidelines, trial bibliographies, and pertinent reviews were examined to ensure the inclusion of relevant trials. The following section reviews data from pivotal trials to review the efficacy of S-ICD for the termination of VT/VF. The S- ICD system consists of a pulse generator positioned over the sixth rib between the midaxillary and anterior axillary line and a tripolar parasternal electrode with the proximal and distal sensing electrodes positioned adjacent to the xiphoid process and manubriosternal junction, respectively. The conversion of the efficacy of the S-ICD after the first shock ranges from 88%-90.1% and 98.2%-100% after 5 shocks based on the current evidence. The device also has a 99% complication-free rate at 180 days with no increased complications even in ESRD patients. The PRAETORIAN trial showed non-inferiority of the S-ICD to transvenous ICD concerning device-related complications or inappropriate shocks in patients. S-ICD has several advantages including no need for fluoroscopy for implantation, decreased risk of infections, complications, and evidence of safety even in high-risk populations like ESRD. The limitations include the inherent lack of pacing abnormalities, the increase in inappropriate shocks compared to transvenous ICD, and non-reliability if there are baseline T wave abnormalities, especially in the inferior leads. Thus, S-ICD can be considered as an alternative to transvenous ICD in patients with an indication for defibrillator therapy but with no indication for pacing.

Cardiovascular disease (CVD) is the leading cause of morbidity and mortality in the world. Mental health disorders are associated with the onset and progression of cardiac disease. The adverse sequelae of this association include worsened quality of life, adverse cardiovascular outcomes, and heightened mortality. The increased prevalence of CVD is partly explained by increased rates of traditional cardiovascular risk factors including hypertension, hyperlipidemia, diabetes mellitus, obesity, and smoking, but mental illness is an independent risk factor for CVD and mortality. Given the association between mental health disorders and poor cardiovascular health, it is vital to have an early and accurate identification and treatment of these disorders. Our review article shares the current literature on the adverse cardiovascular events associated with psychiatric disorders. We present a review on depression, anxiety, bipolar disorder, schizophrenia, type A and D personality disorders, obsessive-compulsive disorder, and stress.

Bereavement due to loss of a partner is one of the most stressful life events, often leading to adverse physiological responses. Spousal loss has been associated with an increased morbidity and mortality, particularly from cardiovascular disease. Use of aspirin and/or beta adrenergic blockers have previously been suggested to play a role in cardiovascular risk associated with early bereavement. However, the available literature regarding this topic is limited. In this review article, we explore the potential beneficial role of aspirin and beta blockers in early bereavement. Our systematic review suggests that most studies have found aspirin and beta blockers to be beneficial in preventing adverse cardiovascular outcomes associated with early bereavement. Further randomized controlled long-term studies are warranted with adequate sample size to clearly establish the role of these medications on cardiovascular disease in late bereavement.

PURPOSE OF REVIEW: Heart failure is a complex clinical syndrome with a substantial disease burden. We aim to review the interventional aspects of management of advanced heart failure, focusing on the role of management of coronary artery disease, valvular heart disease, and mechanical circulatory support. RECENT FINDINGS: The patients with coronary artery disease and heart failure requiring revascularization are at higher risk than the rest of the general population. Coronary artery bypass grafting or percutaneous intervention can be used depending on varied patient characteristics and coronary anatomy. Transcatheter aortic valve implantation, Mitraclip and transcatheter ventricular restoration help in tackling the valvular and left ventricular remodeling concerns often seen in this patient population. Temporary hemodynamic circulatory support helps stabilizing patients in cardiogenic shock while long-term support can help bridge them to more definitive therapies. SUMMARY: The management strategies in this disease state are ever evolving with robust evidence coming in support of interventional therapies whenever deemed appropriate. It is the multidisciplinary patient-centered approach, which yields maximum benefit out of these complex interventions.

Chronic systemic skin disease and cardiovascular disease are multisystem disorders which have been associated with each other for centuries. Recent research has strengthened this association, particularly in systemic inflammatory disease. Here we explore the current literature on psoriasis, hidradenitis suppurativa, lupus erythematosus, acanthosis nigricans, atopic dermatitis, and bullous pemphigoid. Psoriasis is a chronic inflammatory disorder that has been labeled as a risk-modifier for hyperlipidemia and coronary artery disease by the American College of Cardiology ACC lipid guidelines. Cardiovascular disease is also found at a significantly higher rate in patients with hidradenitis suppurativa and lupus erythematosus. Some associations have even been noted between cardiovascular disease and acanthosis nigricans, atopic dermatitis, and bullous pemphigoid. While many of these associations have been attributed to a shared underlying disease process such as chronic systemic inflammation and shared underlying risk factors, these dermatologic manifestations can help to identify patients at higher risk for cardiovascular disease.
