Observational Study
Carotid Duplex Ultrasonography to Assess Severity of Low-Flow Low-Gradient Aortic Stenosis.
Patients with low-flow, low-gradient aortic valve stenosis constitute a substantial subset of all severe aortic stenosis patients. However, assessment of true severity of these patients can be challenging. In this analysis, we study the utility of the common carotid artery waveforms to distinguish true from pseudo-severe low-flow low-gradient aortic stenosis. ⋯ cAT acceleration time may be used to distinguish true from pseudo-severe low-flow, low-gradient aortic valve stenosis.

Atrioventricular block may be idiopathic or a secondary manifestation of an underlying systemic disease. Cardiac sarcoidosis is a significant underlying cause of high-grade atrioventricular block, posing diagnostic challenges and significant clinical implications. This study aimed to assess the prevalence and clinical characteristics of cardiac sarcoidosis among younger patients presenting with unexplained high-grade atrioventricular block. ⋯ Cardiac sarcoidosis was confirmed in one-third of patients ≤ 65 years, who presented with unexplained high-grade atrioventricular block. Cardiac sarcoidosis should be highly suspected in such patients, particularly in males who present with heart failure symptoms or exhibit thicker inter-ventricular septum and right ventricular dysfunction on echocardiography.

Several studies have examined a potential relationship between periodontal disease and cardiovascular disease. This article aims to update the evidence for a potential association by summarizing the evidence for causality between periodontitis and comorbidities linked to cardiovascular disease, including hypertension, atrial fibrillation, coronary artery disease, diabetes mellitus, and hyperlipidemia. We additionally discuss the evidence for periodontal therapy as a means to improved management of these comorbidities, with the larger goal of examining the value of periodontal therapy on reduction of cardiovascular disease risk.

The purpose of this study was to determine whether sleep characteristics are associated with incidence of treated diabetes in postmenopausal individuals. ⋯ Sleep-disordered breathing and short or long sleep duration were associated with higher diabetes risk in a postmenopausal population.
