RESUMO
Resistant hypertension is a condition in which blood pressure remains elevated despite using 3 or more antihypertensive medications. Though contemporary antihypertensive drug therapies have been essential in treating hypertension, in recent years different studies have explored renal denervation (RDN) as an adjunctive or a replacement modality. Here we summarize an open-label, Symplicity HTN 2 trial and 7 randomized, sham-controlled clinical trials: Spyral-HTN OFF MEDS (Spyral Pivotal), Spyral-HTN ON MEDS, RADIANCE-HTN SOLO, RADIANCE-HTN TRIO, RADIANCE II, SYMPLICITY-HTN 1, and SYMPLICITY-HTN 3, which evaluated safety and efficacy of multiple renal denervation systems (RDN) at lowering blood pressure from baseline, and in comparison, to control group. Prior systematic reviews and meta-analyses evinced a modest reduction of ambulatory and office blood; however, these trials and analyses were limited by short-term follow-up. In our updated comprehensive literature review we summarize the short-term, and long-term effects of RDN, based on the latest randomized clinical trials. Our conclusions based on each summary are unanimous with previous literature findings.

Heart failure is a significant cause of morbidity and mortality worldwide. Despite advancements in guideline-directed medical therapy and improvements in device-based therapies, patients with advanced heart failure have high rates of mortality regardless of ejection fraction. For patients with reduced ejection fraction who meet criteria, cardiac resynchronization therapy or implantable cardiac defibrillators are options available to improve outcomes. However, not all heart failure patients meet those criteria. Cardiac contractility modulation is an innovative therapy that serves to improve functional outcomes and quality of life, while also modifying pathologic gene expression and preventing further remodeling. In this article, we aim to discuss the major clinical trials investigating cardiac contractility modulation as a suitable therapy for patients with advanced heart failure.

INTRODUCTION: We analyzed trends, causes and predictors of 30-days readmission in cardiac amyloidosis and inspected the impact of these readmissions on mortality, morbidity, and utilization of healthcare resources. METHODS: Heart Failure with cardiac amyloidosis patients were selected from National readmission Database (NRD) using ICD-10 CM codes. Patients younger than 18 years, elective readmissions, readmissions due to trauma, patients with missing data and December 2018 admissions were excluded. Primary outcome was all-cause 30-day readmissions rate, secondary outcomes were factors associated with 30-days readmissions and their effect on morbidity, mortality, and healthcare resource utilization. RESULTS: Out of 4123 total heart failure with cardiac amyloidosis index admissions in 2018, 3374 patients were included in final analysis. 19.6% were readmitted within 30 days. Readmitted patients were younger, sicker, admitted to small or large hospital. Hypertensive heart and Chronic Kidney Disease (CKD Stage I-IV) with Congestive Heart Failure (CHF), hypertensive heart and CKD (Stage V) or End Stage Renal Disease (ESRD) with CHF, hypertensive heart disease with CHF, acute kidney failure, and sepsis were the most common causes of readmissions. Young age, admission to small and large size hospitals were independent predictors of 30-day readmissions. Readmissions had higher mortality, costed 6.6 extra in hospital days to patients and $16380 per admission to healthcare system. CONCLUSIONS: Cardiac amyloidosis readmissions were associated with increased morbidity and mortality of patients and extra burden on the healthcare system. There is a need to identify patients at risk for readmissions to improve patient outcomes and decrease healthcare cost.
RESUMO
Cardiovascular disease remains the leading cause of death globally and here in the United States. Diet has a major impact on the pathogenesis of atherosclerosis and subsequent cardiovascular morbidity and mortality. An unhealthy diet is the most significant potential behavioral and modifiable risk factor for ischemic heart disease. Despite these established facts, dietary interventions are far less frequent than pharmaceutical and procedural interventions in the management of cardiovascular disease. The beneficial effects of a plant-based diet on cardiovascular morbidity and mortality have been demonstrated in a number of recent clinical studies. The significant findings of each study are discussed in this review article, highlighting the role of a healthy plant-based diet in improving cardiovascular outcomes. From a clinician's standpoint, the knowledge and understanding of the facts and data points from these recent clinical studies would ensure more effective patient counseling on the substantial benefits of dietary interventions.

Percutaneous coronary intervention with a drug eluting stent requires administration of dual anti platelet therapy (DAPT) to prevent thrombotic complications. Optimal duration of this therapy remains unclear especially for patients with high bleeding risk. Since the risk of stent thrombosis is highest immediately following stent implantation, longer term DAPT therapy may confer additional risk of harm rather than benefit for this subset of patients. Hence, short duration DAPT therapy may be a reasonable alternative. Multiple studies have demonstrated their noninferiority compared to traditional duration of DAPT in preventing thrombotic complications following stent implantation while at the same time keeping bleeding risk at a minimum. Here, we discuss short duration DAPT as a treatment option and summarize the major clinical trials that were conducted recently demonstrating the results of short duration DAPT.

BACKGROUND Takotsubo cardiomyopathy, also referred to as apical ballooning syndrome (ABS), stress cardiomyopathy, or broken heart syndrome, initially described in Japan, is characterized by transient wall motion abnormalities involving the apical segment. Several variants have been described, including reverse type, mid-ventricular type, and the focal type. In the reverse type, there is basal hypokinesis and apical hyperkinesis. Stress cardiomyopathy is most likely to occur in middle-aged women and the underlying etiology is believed to be related to catecholamine release due to intense stress. CASE REPORT We report an extremely rare case of reverse takotsubo cardiomyopathy (rTTC) in a young woman with COVID-19 who was treated with Casirivimab-Imdevimab therapy. Our report is the second to reveal rTTC in a patient with COVID-19 in which obstructive coronary artery disease was definitively ruled out by coronary CT angiography. CONCLUSIONS Cardiovascular involvement in COVID-19 has been linked to increased morbidity and mortality rates. Recent reports have suggested the occasional occurrence of TTC and the rare occurrence of reverse takotsubo cardiomyopathy (rTTC) in patients with COVID-19. In fact, to the best of our knowledge, this is only the fifth reported case of rTTC in a patient with COVID-19; importantly, 3 out of the 4 of the previous reported cases lacked definitive ischemic work-up to rule out obstructive coronary artery disease due to the critical condition of the patients.

Mitral regurgitation is the most common valvular disease in the US and the second most common worldwide. Left untreated, it can lead to the development of heart failure, giving rise to increased mortality rates. Mitral valve intervention is usually indicated in severe mitral regurgitation at the onset of symptoms, even if the function of the left ventricle is preserved. A surgical approach is generally favored according to current guidelines, with excellent clinical outcomes. However, the emergence of novel data from contemporary trials indicates that percutaneous, catheter-based approach may have similar improvements in mortality outcomes while maintaining a superior safety profile when compared to the surgical approach. Here, we discuss transcatheter mitral valve repair as a treatment option for mitral regurgitation and summarize the major clinical trials which were recently conducted on transcatheter repair.

BACKGROUND The eustachian valve is rarely involved in bacterial endocarditis. Patients who present with bacteremia and evidence of organic septic emboli should raise the suspicion of endocarditis as a possible differential diagnosis. This case series describes 2 unique cases of eustachian valve endocarditis (EVE) in patients who had a history of intravenous drug use; although 63% of EVE is caused by Staphylococcus aureus, the causative agent in our first case was methicillin-resistant Staphylococcus epidermidis (MRSE), which is only the third reported case of EVE caused by Staphylococcus epidermidis. Of note, the previous 2 cases of MRSE EVE were also found to be associated with cardiovascular hardware. CASE REPORT The first case of the series describes EVE by MRSE with an endovascular graft acting as the nidus of infection. Second case of EVE was caused by methicillin-sensitive Staphylococcus epidermidis (MSSA), the source of bacteremia being a rectovesicular abscess. Although initial transthoracic echoes were negative in both cases, subsequent transesophageal echoes were able to detect vegetations on the eustachian valves. Treatment included 4-6 weeks of culture-directed antibiotic therapy for both of our cases. CONCLUSIONS EVE may be an under-diagnosed sequelae of staphylococcal bacteremia, especially in the intravenous drug abuse population, further reinforcing the importance of systemically visualizing all cardiac valves, including the eustachian valves, while performing echocardiography.

Background: Thoracic radiation predisposes patients to accelerated coronary artery disease. There is a paucity of data in both short-term and long-term outcomes following revascularization in patients who have undergone thoracic radiation. Methods: We performed a search of the Medline, Cochrane, and Scopus databases for studies that compared outcomes in cancer patients who have undergone thoracic radiation and percutaneous coronary intervention (PCI). The primary outcome of our meta-analysis was all-cause mortality. Secondary outcomes included cardiac mortality, myocardial infarction (MI), and restenosis. Results: The analysis included four observational studies with a total of 13,941 patients for the primary outcome of all-cause mortality. There were a total of 1,322 patients analyzed for cardiac mortality, 13,103 for MI, and 10,530 for restenosis. The longest follow-up for the primary outcome was 16 years. There was statistically significant higher risk of all-cause mortality in patients who underwent thoracic radiation (risk ratio (RR): 1.29, 95% confidence interval (CI): 1.08 - 1.54, P = 0.004). There was no statistically significant difference in cardiac mortality (RR: 1.15, 95% CI: 0.83 - 1.61, P = 0.40), MI (RR: 1.01, 95% CI: 0.20 - 5.08, P = 0.99), and restenosis (RR: 1.92, 95% CI: 0.24 - 15.35, P = 0.54). Conclusion: In this meta-analysis, we found a higher risk of all-cause mortality in patients with a history of thoracic radiation undergoing PCI, likely from underlying malignancy itself.
RESUMO
Inflammation is a major contributing factor in the development of cardiovascular disease (CVD) and has been a popular topic of discussion as it provides a potential therapeutic target to reduce disease progression. Multiple inflammatory markers have been linked with progressive atherosclerosis which includes interleukin-6, tumor necrosis factor-α, C-reactive protein amongst others, this article aims to review current literature to evaluate the effectiveness of anti-inflammatory therapies in cardiovascular disease.

Amyloidosis is an infiltrative disease with severe impact on the cardiac anatomy resulting in structural changes1. Mitral valve insult from the infiltrative process, although rare, has been known to cause severe mitral regurgitation4. Due to underlying comorbidities these patients may not be surgical candidates.17,18,19,20 The role of percutaneous mitral valve repair in cardiac amyloidosis has been described in a few prior cases.4,15 We review the epidemiology, diagnosis, and treatment of cardiac amyloidosis. We also highlight prior cases described in the literature of cardiac amyloidosis and severe mitral regurgitation, while discussing the role of percutaneous mitral valve repair in these patients.

Soluble guanylate cyclase (sGC) agents have been shown to have possible beneficial effects in heart failure treatment. Unfortunately, the role of sGC in HFpEF has not been shown to be efficacious based on recent trials. The CAPACITY HFpEF and VITALITY-HFpEF trials independently showed that sGC does not improve 6-minute walk test (6MWT) distance or the Kansas City Cardiomyopathy Questionnaire (KCCQ) physical limitation score (PLS). The objective of this study was to analyze current data on the 6MWT and KCCQ PLS score from trials that included patients with HFpEF treated with sGC. Using MEDLINE and Cochrane databases, meta-analysis and systematic review was performed looking at data in the CAPACITY HFpEF and VITALITY-HFpEF trials. For safety analysis we evaluated serious adverse events between the CAPACITY HFpEF, VITALITY-HFpEF, SOCRATES-PRESERVED, and DILATE-1trials. A total of 2 trials were analyzed to assess 6MWT and KCCQ score. The total number of combined patients from both trials assessing 6MWT distance in sGC vs placebo therapy were 620 with 309 in the treatment group and 311 in the placebo group. The total number of combined patients from both trials assessing KCCQ score outcomes were 583 with 280 in the treatment group and 303 in the placebo group. A total of 4 trials were evaluated for safety analysis with a total of 987 patients with 529 in the treatment group and 458 in the placebo group. The analysis did not demonstrate significant difference in 6MWT (Pâ¯=â¯0.97), KCCQ PLS (Pâ¯=â¯0.83), or serious adverse events (Pâ¯=â¯0.67).

Heart failure is a leading global pandemic and a cause of economic burden. Although, treatments exist to help symptomatic alleviation, patient compliance and monitoring is the basis of ensuring efficacy. With devices that allow for remote wireless PA pressure monitoring such as CardioMEMS, the inconsistency in patient reporting and factors such as symptoms and hospitalizations can be reduced. A systematic review and meta-analysis utilizing the MEDLINE, Cochrane, and Scopus database was performed to identify randomized and non-randomized clinical trials evaluating baseline characteristics and hospitalizations. Five trials for the systematic review and 2 trials for the meta-analysis meeting the inclusion and exclusion criteria were included. Baseline characteristics included an average age of 64.6 years, male predominance, mean BMI of 29.6, predominance of HFrEF, hypertension the most prevalent comorbidity, and a mean PA pressure of 27.2 mm Hg. The follow-up periods ranged from 90 days to 12 months. There was a total of 64 adverse events, mostly non-serious. Patients who underwent remote PA monitoring were less likely to be hospitalized compared with patients who did not (Odds Ratio: 0.52; 95% Confidence Interval 0.39, 0.69). Remote PA pressure monitoring allows for reduced hospitalizations. With the recent and now resurging SARS-CoV-2 pandemic, devices such as CardioMEMS can allow for heart failure patients to be managed from home to not only reduce hospitalizations but for symptom prevention and management.

Severe coronary artery calcification (CAC) is associated with high rate of procedural complications. The current techniques that facilitate percutaneous coronary interventions in moderate to severe CAC have significant risk of complications, including periprocedural myocardial infarction , dissection, perforation and transient atrioventricular block. Coronary Intravascular lithotripsy (IVL) is a novel technology for the treatment of moderate to severe calcified lesions. IVL uses sonic pressure waves to break down the calcium deposits with no to minimal impact on the blood vessel tissues, which makes IVL a safe option with high procedural success and minimal complications. Here, we discuss coronary IVL as a treatment option for CAC and summarize the major clinical trials performed evaluating the safety and outcome of IVL.

Despite the currently established treatment for heart failure (HF), HF remains a growing public healthcare problem with an increasing burden. Therefore, novel therapeutic innovations are needed to overcome this issue and improve HF prognosis. Sodium-glucose co-transporter-2 inhibitors (SGLT2i) are state-of-the-art in type 2 diabetes mellitus management. They inhibit the reabsorption of glucose from the proximal renal tubules, leading to increased glycosuria and decreased plasma glucose levels. SGLT2i use is growing significantly, especially after recent clinical trials demonstrating favorable cardiovascular and renal protective effects independently of blood glucose-lowering. The mechanisms by which SGLT2i demonstrate their cardio-renal protective effects remain incompletely understood but are thought to be related to potential diuretic and natriuretic effects along with other mechanisms that will be discussed in this article. Over the past few years, there has been significant research on the safety, efficacy, and quality of this class of medications. Here, we review the current guideline-directed medical therapy for HF, focus on SGLT2i mechanism of action and potential role in HF patients, and finally summarize the cardiovascular clinical trials with SGLT2.
RESUMO
BACKGROUND: Atrial fibrillation (AF) is one of the leading causes of acute ischemic stroke requiring anticoagulation. Many patients experience treatment interruption in the hospital setting. The aim of this study was to evaluate the effect of anticoagulation interruption on short-term risk of ischemic stroke in hospitalized patients with AF. METHODS: We performed a retrospective medical record review using the Hospital Corporation of America (HCA) database. We included patients admitted to our institution between December 2015 and December 2018 who had a prior history of AF. Patients were excluded if they had ischemic stroke, hemorrhagic stroke, history venous thromboembolism or mechanical valve on admission. We compared the incidence of ischemic stroke in patients in whom anticoagulation was interrupted for more than 48 h to those who continued anticoagulation. RESULTS: A total of 2,277 patients with history of AF were included in the study. In this cohort, 79 patients (3.47%) had anticoagulation interruption of more than 48 h during their hospital stay. There was no difference in incidence of stroke between the interruption and no interruption groups (1.27% (n = 1) vs. 0.23% (n = 5), P = 0.19). Interruption of anticoagulation did not associate with a significant increase in the risk of in-hospital ischemic stroke. CHA2DS2VASc score was a strong predictor of in-hospital stroke risk regardless of anticoagulation interruption (odds ratio: 7.199, 95% confidence interval: 2.920 - 17.751). CONCLUSION: In this study, the in-hospital incidence of ischemic stroke in patients with AF did not significantly increase by short-term anticoagulation interruption.
RESUMO
Sarcoidosis is an infiltrative disease known to affect multiple layers of the heart.1 Although rare, aortic valve involvement has been seen.17,18 The role of transcatheter aortic valve replacement (TAVR) has been described in amyloidosis,4 a well-known infiltrative disease, but not in sarcoidosis. As the awareness of cardiac sarcoidosis grows,17 as in amyloidosis, its impact on the aortic valve will grow too. Our review highlights the epidemiology, pathophysiology, and treatment of cardiac sarcoidosis with a discussion for TAVR in patients affected by aortic valve insult.

Congestive heart failure (HF) remains a major cause of cardiac-related morbidity and mortality, despite major therapeutic advancements. A newer class of medications has recently been developed which targets the root cause of HF, which is reduced myocardial contractility. This article aims to highlight the cardiac myosin activator class of drugs and the trials to date highlighting their effects on HF outcomes.
RESUMO
Acute pulmonary emboli are a major cause of morbidity and mortality and require prompt evaluation, diagnosis, and treatment. To date, anticoagulation using low molecular weight heparin or non-Vitamin K oral anticoagulants has been the mainstay of treatment in the subset of patients in whom pulmonary embolism does not compromise hemodynamics. On the other hand however, patients with massive pulmonary embolism and shock, thrombolytic therapy is necessary. This raises the question whether ultrasound-assisted catheter directed thrombolytic delivery might be superior to systemic administration. This review article aims to consolidate recent literature to help achieve a better understanding toward the utility of catheter directed therapy.

Over the years, aspiration thrombectomy for management of acute coronary syndrome was the center of discussion however due to multiple randomized control trials which did not provide sufficient evidence supporting use of this approach, this method is not routinely used. The benefit of this approach remains unknown, however, it is important to acknowledge the evolution of aspiration catheters and their potential in minimizing complications which were previously the set back of this approach. We provide a comprehensive review of the previous trials and how those catheters have since evolved significantly.
