Comparative Study
Comparison of 24-hour Holter monitoring with 14-day novel adhesive patch electrocardiographic monitoring.
Cardiac arrhythmias are remarkably common and routinely go undiagnosed because they are often transient and asymptomatic. Effective diagnosis and treatment can substantially reduce the morbidity and mortality associated with cardiac arrhythmias. The Zio Patch (iRhythm Technologies, Inc, San Francisco, Calif) is a novel, single-lead electrocardiographic (ECG), lightweight, Food and Drug Administration-cleared, continuously recording ambulatory adhesive patch monitor suitable for detecting cardiac arrhythmias in patients referred for ambulatory ECG monitoring. ⋯ Over the total wear time of both devices, the adhesive patch monitor detected more events than the Holter monitor. Prolonged duration monitoring for detection of arrhythmia events using single-lead, less-obtrusive, adhesive-patch monitoring platforms could replace conventional Holter monitoring in patients referred for ambulatory ECG monitoring.

Randomized Controlled Trial
Prevalence, predictors, and outcomes in treatment-resistant hypertension in patients with coronary disease.
Increasingly, apparent treatment-resistant hypertension has been recognized. However, much of the prevalence, predictors, and outcomes are largely unknown, especially in patients with coronary artery disease. ⋯ In patients with coronary artery disease, apparent treatment-resistant hypertension is associated with a marked increase in the risk of cardiovascular morbidity and mortality, including an increase in all-cause death.

Pulmonary emphysema is divided into 3 major subtypes at autopsy: centrilobular, paraseptal, and panlobular emphysema. These subtypes can be defined by visual assessment on computed tomography (CT); however, clinical characteristics of emphysema subtypes on CT are not well defined. We developed a reliable approach to visual assessment of emphysema subtypes on CT and examined if emphysema subtypes have distinct characteristics. ⋯ Emphysema subtypes on CT are common in smokers with and without COPD. Centrilobular and panlobular emphysema, but not paraseptal emphysema, have considerable symptomatic and physiological consequences.

Nonsteroidal anti-inflammatory drugs (NSAIDs) other than aspirin have been linked to heart failure, salt retention, adverse ventricular remodeling, and thrombosis. We therefore sought to assess their impact on cardiovascular events in outpatients with stable atherothrombotic disease. ⋯ Among patients with stable atherothrombosis, NSAID use is associated with a higher risk of myocardial infarction, stroke, and hospitalizations for both ischemia and heart failure.
