Written by Michael Doyle DO and Timothy Palmieri MD. Edited by Bracey, Meyers, Grauer, and Smith A 50-something-year-old female with a history of an unknown personality disorder and alcohol use disorder arrived via EMS following cardiac arrest with return of spontaneous circulation. The described rhythm was an irregular, wide complex rhythm. By EMS report, open pill bottles were found nearby at the scene, including quetiapine, fluoxetine, hydroxyzine, and gabapentin.

Background Acute myocardial infarction (AMI) is one of the most lethal complications of COVID-19 hospitalization. In this study, we looked for the occurrence of AMI and its effects on hospital outcomes among COVID-19 patients. Methods Data from the 2020 California State Inpatient Database was used retrospectively. All COVID-19 hospitalizations with age ≥ 18 years were included in the analyses.

Abstract RETRO-mapping was developed to automate activation mapping of atrial fibrillation (AF). We used the algorithm to study the effect of pulmonary vein isolation (PVI) on the frequency of focal, planar, and colliding wavefronts in persistent AF. An AFocusII catheter was placed on the left atrial endocardium to record 3 s of AF at six sites pre and post-PVI in patients undergoing wide circumferential PVI for persistent AF.

Hypertension, Ahead of Print. Almost a hundred years have passed since obstruction of the renal artery has been recognized to raise blood pressure. By now chronic renovascular disease (RVD) due to renal artery stenosis is recognized as a major source of renovascular hypertension and renal disease. In some patients, RVD unaccompanied by noteworthy renal dysfunction or blood pressure elevation may be incidentally identified during peripheral angiography.

Abstract Atrial fibrillation (AF) is currently defined as symptomatic by asking patients if they are aware of when they are in AF and if they feel better in sinus rhythm. However, this approach of defining AF as symptomatic and asymptomatic fails to adequately consider the adverse effects of AF in patients who are unaware of their rhythm including progression from paroxysmal to persistent AF, and the development of dementia, stroke, sinus node dysfunction, valvular regurgitation, ventricular dys

Hypertension, Ahead of Print. BACKGROUND:Abnormal orthostatic blood pressure (BP) regulation may result in cerebral hypoperfusion and brain ischemia and contribute to dementia. It may also manifest as early symptoms of the neurodegenerative process associated with dementia. The relationship between the magnitude and timing of orthostatic BP responses and dementia risk is not fully understood.METHODS:We conducted a prospective cohort analysis of the associations of orthostatic BP changes and self

BACKGROUND:Heart failure with preserved ejection fraction is associated with significant functional limitations, yet treatments for improving exercise performance have been elusive. We sought to explore the association between prespecified patient characteristics and changes in 6-minute walk distance that constitute a clinically significant response to dapagliflozin.METHODS:We performed a responder analysis to unde

Heart failure with preserved ejection fraction (HFpEF) has become the leading form of heart failure worldwide, particularly among elderly patient populations. HFpEF is associated with significant morbidity and mortality that may benefit from incorporation of palliative care (PC).

Circulation, Ahead of Print. Background: Atrial fibrillation (AF) is common in patients undergoing transcatheter aortic valve replacement (TAVR) and is associated with increased risk of bleeding and stroke. While left atrial appendage occlusion (LAAO) is approved as an alternative to anticoagulants for stroke prevention in patients with AF, placement of these devices neither in patients with severe AS, nor at the same time as TAVR, has been extensively studied.Methods: WATCH-TAVR was a multicent
