Gamification-augmented home-based exercise for peripheral artery disease: Rationale and design of the GAMEPAD Study.

Background: Supervised exercise therapy improves walking performance, functional capacity, and quality of life in patients with peripheral artery disease (PAD). However, few patients with PAD are enrolled in supervised exercise programs, and there are a number of logistical and financial barriers to their participation. A home-based walking intervention is likely to be more accessible to patients with PAD, but no fully home-based walking program has demonstrated efficacy.

Referral Rates for Cardiac Rehabilitation Among Eligible Inpatients After Implementation of a Default Opt-Out Decision Pathway in the Electronic Medical Record.

This quality improvement study assesses referral rates for cardiac rehabilitation after a default opt-out option is added to the decision pathway in the electronic medical record.

Patient Characteristics Associated With Telemedicine Access for Primary and Specialty Ambulatory Care During the COVID-19 Pandemic.

Importance: The coronavirus disease 2019 (COVID-19) pandemic has required a shift in health care delivery platforms, necessitating a new reliance on telemedicine.

Objective: To evaluate whether inequities are present in telemedicine use and video visit use for telemedicine visits during the COVID-19 pandemic.

Design, Setting, And Participants: In this cohort study, a retrospective medical record review was conducted from March 16 to May 11, 2020, of all patients scheduled for telemedicine visits in primary care and specialty ambulatory clinics at a large academic health system.

Loss-Framed Financial Incentives and Personalized Goal-Setting to Increase Physical Activity Among Ischemic Heart Disease Patients Using Wearable Devices: The ACTIVE REWARD Randomized Trial.

Background: Regular physical activity reduces the risk of cardiovascular events, but most ischemic heart disease (IHD) patients do not obtain enough.

Methods And Results: ACTIVE REWARD (A Clinical Trial Investigating Effects of a Randomized Evaluation of Wearable Activity Trackers with Financial Rewards) was a 24-week home-based, remotely monitored, randomized trial with a 16-week intervention (8-week ramp-up incentive phase and 8-week maintenance incentive phase) and an 8-week follow-up. Patients used wearable devices to track step counts and establish a baseline.

Systemic Inflammation Associated With World Trade Center Dust Exposures and Airway Abnormalities in the Local Community.

Background: Destruction of the World Trade Center (WTC) towers on September 11, 2001, released massive dust, gas, and fumes with environmental exposures for community members. Many community members have lower respiratory symptoms (LRSs) that began after September 11, 2001, and remain persistent. We evaluated whether systemic inflammation measured by C-reactive protein was associated with WTC dust exposures, persistent LRS, and lung function.

Cardiac imaging in the geriatric population: what do we think we know, and what do we need to learn?

Cardiac imaging plays an important role in coronary artery disease (CAD), congestive heart failure (HF) and valvular heart disease (VHD) in the elderly. Imaging defines the structure and function of the cardiac system, refining the understanding of patients' anatomy and physiology and informing a host of clinical care decisions, including prognosis. Yet there is a paucity of evidence to guide the rational use of many imaging modalities in patients of advanced age, a population with considerable clinical heterogeneity, high prevalence and burden of cardiovascular disease (CVD) and atypical presentations of CVD.

Appropriateness of statins in patients aged ≥80 years and comparison to other age groups.

In patients aged ≥80 years without previous coronary artery disease, peripheral vascular disease, or cerebrovascular disease, no evidence has shown a benefit from statin therapy. We examined the prevalence of statin use in patients aged ≥80 years for the indication of primary prevention. We reviewed the comprehensive electronic health records at the Geisinger Health System in Pennsylvania for all patients aged >55 years with ≥1 primary care encounter from January 24, 2004 and December 31, 2009.

Sex and race are associated with the absence of epicardial coronary artery obstructive disease at angiography in patients with acute coronary syndromes.

Background: A substantial minority of patients with acute coronary syndromes (ACS) do not have a diameter stenosis of any major epicardial coronary artery on angiography ("no obstruction at angiography") of > or = 50%. We examined the frequency of this finding and its relationship to race and sex.

Hypothesis: Among patients with myocardial infarction, younger age, female sex and non-white race are associated with the absence of obstructive coronary artery disease at angiography.
