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.

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.

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.

Objective of this retrospective study was to determine if long-term continuous cardiac monitoring with Implantable loop recorder (ILR) in patients with Cryptogenic strokes or TIA is superior at detecting Atrial Fibrillation (AF) than 30-day Event Monitor (EM) and 48-hour Holter Monitor (HM). Furthermore, we aimed to deduce if uncovering AF leads to lower risk of future ischemic strokes, or reduction in mortality. In 20%-30% cases, the cause of stroke remained unexplained after diagnostic workup which has led to coining of the term, Cryptogenic Stroke (CS). Undiagnosed AF is a prime suspect in CS, but guidelines do not recommend initiation of anticoagulation unless AF has formally been detected. IRB approved retrospective study included patients with at least 1 episode of ischemic stroke or TIA without identifiable cause and was monitored with either HM, EM or ILR to diagnose any undiscovered AF. All patients (nâ¯=â¯531) had at least 1 year, and up to 3 years, of follow-up after device placement. Chi-Squared analysis and Multivariable logistic regression demonstrated no statistically significant difference among 3 devices for detection of AF within 1 month of index stroke but a significant difference in AF detection was observed at 6, 12 and 24 months. Cox proportional hazard model showed device type had no significant impact on secondary outcomes: Subsequent ischemic stroke or TIA, Initiation of anticoagulation, Mortality and Incidence of major bleeding. Despite the superiority of AF detection by ILR, it is not superior to HM or EM in lowering the risk of subsequent stroke or TIA, or in reducing mortality.

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.

BACKGROUND: Intraoperative anaphylaxis is a life threatening and multiorgan system hypersensitivity reaction that frequently leads to cessation of operations. Despite the incidence of Cefazolin allergy being on the rise, the cases of anaphylaxis to Cefazolin during surgeries and its management are seldom reported. CASE PRESENTATION: We present two patients with no known beta-lactam allergy and end stage kidney disease who received perioperative intravenous Cefazolin for planned deceased kidney transplant surgery at our academic medical center. Both patients developed anaphylaxes approximately three minutes following the administration of the antibiotic and experienced severe, refractory hypotension that required the use of vasopressors. The severity of the anaphylactic reactions resulted in the cessation of the transplant operation and multiple days of intensive care unit admission. CONCLUSION: Peri-or intraoperative anaphylaxis to Cefazolin is on the rise and its consequences in transplant candidates are even more dire given the pre-existing end organ failure, financial burden for health care system, potential loss of donor organs, and emotional burden for recipients and their families. These are the first two cases of reported Cefazolin-induced anaphylaxis that actually resulted in aborting the kidney transplant operation. In addition, cases of previously reported Type 1 hypersensitivity to Cefazolin as prophylaxis for operations were reviewed and the allergy workups were discussed.

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.

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.
