Arrhythmia Masquerading as Cardiac Ischemia

A 45-year-old woman with a history of medication-controlled essential hypertension, stage 2 chronic kidney disease, type 2 diabetes mellitus, and a pack-a-day cigarette habit presented less than 60 minutes after acute onset of severe shortness of breath that awoke her from sleep. She had felt well the previous day, and went to bed with no complaints.   Around 4 a.m., she woke up from sleep very dyspneic, with moderate chest “discomfort” over her left chest that radiated to her back and was unchanged by position or respirations. She denied other symptoms such as fever, cough, nausea, vomiting, numbness, or abdominal pain.   Her blood pressure was 138/76 mm Hg, pulse 87 bpm, respiratory rate 26, and SpO2 was 95%. She was afebrile, and her physical exam was unremarkable: clear breath sounds, no S3 or murmur, and no lower extremity edema. She felt slightly less dyspneic with supplemental oxygen. She was treated with an aspirin orally. A sublingual nitroglycerin improved her chest discomfort, and a chest radiograph was clear. Her presenting electrocardiogram is shown in Figure 1.   The ECG is consistent with a supraventricular tachycardia (SVT), likely to be atypical atrioventricular nodal reentrant tachycardia (AVNRT). The key feature to note is the absence of P waves before the QRS complex and retrograde P-waves evident following the QRS as part of the T-wave. The discomfort in her chest and neck is likely secondary to atrial contraction against ...

Authors: Rombauts A, Abelenda-Alonso G, Cuervo G, Gudiol C, Carratalà J Abstract INTRODUCTION: Despite adequate antibiotic coverage, community-acquired pneumonia (CAP) remains a leading cause of hospitalization and mortality worldwide. It induces both a local pulmonary and a systemic inflammatory response, particularly significant in severe cases. The intensity of the dysregulated host response varies from patient to patient and has a negative impact on survival and other outcomes. AREAS COVERED: This comprehensive review summarizes the pathophysiological aspects of the inflammatory response in CAP, brie...

We describe the most highly recommended generic and disease-specific PRO tools in SCD and discuss the challenges of incorporating them in clinical practice. EXPERT OPINION: PRO measures are essential to incorporate into SCD clinical trials either as primary or secondary outcomes. The use of PRO measures in SCD facilitates a patient-centered approach, which is likely to lead to improved outcomes. Significant challenges remain in adapting PRO tools to routine clinical use and in developing countries. PMID: 33034214 [PubMed - as supplied by publisher]

Authors: Musio F Abstract INTRODUCTION: Anemia has and will continue to be a central theme in medicine particularly as clinicians are treating a burgeoning population of complex multi-organ system processes. As a result of multiple randomized controlled trials (RCTs), meta-analyses, and societal recommendations overly restrictive paradigms and under-administration of erythropoiesis stimulating agents (ESAs) have likely been followed by clinicians among all specialties. AREAS COVERED: A review of anemia in the context of chronic kidney disease, hematologic malignancies and cancer is presented with focus on the e...

Authors: Bergland OU, Søraas CL, Larstorp ACK, Halvorsen LV, Hjørnholm U, Hoffman P, Høieggen A, Fadl Elmula FEM Abstract PURPOSE: The blood pressure (BP) lowering effect of renal sympathetic denervation (RDN) in treatment-resistant hypertension shows variation amongst the existing randomised studies. The long-term efficacy and safety of RDN require further investigation. For the first time, we report BP changes and safety up to 7 years after RDN, compared to drug adjustment in the randomised Oslo RDN study. MATERIALS AND METHODS: Patients with treatment-resistant hypertension, defined...

Authors: Zhang W, Xu JZ, Lu XH, Li H, Wang D, Wang JG Abstract PURPOSE: We hypothesise that dietary sodium intake interacts with serum uric acid to influence blood pressure (BP) in children and adolescents. In the present study, we investigated ambulatory BP in relation to hyperuricaemia, dietary sodium intake and their interaction in children and adolescents with hypertension. MATERIALS AND METHODS:  A total of 616 study participants were 10-24 years old and had primary hypertension diagnosed after admission in a specialised inpatient ward. Ambulatory BP monitoring was performed during hospitalisat...

Currently in fellowship doing bread/butter procedures (MBB, epidurals, PNB, few SCS/PNS trials, etc.) and just interviewed at a private practice spot where they do a lot of procedures that I will have not done any training in prior to graduating (e.g. IT pump, SI fusion, Vertiflex, Kypho, MILD, Discectomy, lots of SCS/PNS trials etc) and significant amount of "OR pain procedures" at a very busy practice seeing 30-40 pts/day - how many of you are commonly performing these procedures and are... private practice concern
