Social Media Use and Community-Based Cardiovascular Health-care Professionals: Perception versus Reality.

Social media use has dramatically increased in the past two decades. This growth has been seen in the health-care field as well. Social media is being used for a variety of activities including networking, education, public health, and marketing. Health-care professionals in cardiology participate in social media to varying degrees and in different ways. Current studies have focused primarily on physicians who have an established presence on social media. To learn more about the social media habits of community-based cardiology providers, we queried attendants at a cardiovascular conference held by our health-care system. The purpose of this article is to: Highlight the social media habits of a range of community-based cardiology providers and distinguish between producing and consuming social media. There is a predominance of social media content consumers compared to producersOutline important considerations when assessing the risks and benefits of social media use and the perceived concerns of cardiology health-care professionalsEmphasize the need to incorporate guidelines for social media use into institutional policies and provide training on social media use to the health-care community.

Cardiovascular Impact of Eating Disorders in Adults: A Single Center Experience and Literature Review.

Eating disorders have multiple medical sequelae, including potentially life-threatening cardiovascular complications. This article describes our cardiology practice experience of treating adults with eating disorders in the outpatient setting and documents baseline cardiac findings in this complex patient population. We describe our findings in patients across the spectrum of eating disorders; past studies have generally focused on anorexia only. This article also includes a review of the current literature on cardiovascular complications associated with disordered eating.

Influence of 99mTc-tetrofosmin SPECT myocardial perfusion imaging on the prediction of future adverse cardiac events.

BACKGROUND: The impact of myocardial perfusion imaging (MPI) on prediction of risk for future cardiac events was examined by comparing predictions based on clinical information alone and in combination with MPI findings. METHODS AND RESULTS: A 3-cardiologist Cardiac Event Prediction Panel (CEPP) estimated three-year cardiac event (non-fatal MI; aborted sudden cardiac death; cardiac death) risk based on clinical data (C) for 371 subjects. CEPP repeated this estimation after receiving Summed Stress Scores (SSS) and Summed Rest Scores (SRS) from blinded reading of rest-stress (99m)Tc-tetrofosmin MPI SPECT studies (C + MPI). The C and C + MPI estimates were then compared with three-year and total event rates. MPI was normal (SSS 13) in 77 (21%). Eighteen cardiac events occurred within 3 years and 33 occurred during a mean follow-up of 3.9 years. C + MPI estimates of low risk (<1-1.5%/year) identified significantly more patients who did not have events than C. C + MPI three-year event-rate predictions were more accurate than those made with C (P < .01). C + MPI categorization also provided better delineation of incremental risk on time-to-event analyses. CONCLUSIONS: (99m)Tc-tetrofosmin MPI single photon emission computed tomography (SPECT) findings significantly improve accuracy of cardiac event rate prediction compared to those based on clinical information alone.

History of the evolution of echocardiography.

Echocardiography provides information regarding cardiac morphology, function and hemodynamics non-invasively. It is the most frequently performed cardiovascular examination after electrocardiography and chest X-ray. In less than half a century, this technique has evolved to a mainstay of cardiovascular medicine. The historical evolution of echocardiography is succinctly described including that of M-mode, two-dimensional, Doppler, stress, transesophageal, intraoperative, contrast, digital, three-dimensional and intracardiac echocardiography.
