I recently saw a very interesting patient. 20 year old male college student (whom I will call Mr. X) with no known past medical history was referred to the medical clinic by his dentist for high blood pressure. During the office visit, Mr. X did not complain of any symptoms and said that he felt fine. On pressing a little further he said that at times he had headaches for which he takes over the counter painkillers. Join discussion...

Surgeons at the Methodist DeBakey Heart Center in Houston were among the first in the U.S. to implant a new, less invasive stent graft designed to reduce the risk of blood clots in patients treated for peripheral arterial disease (PAD), which affects as many as 12 million Americans over the age of 50. The new graft, approved for use in the U.S. this month, is the first vascular stent graft available in the U.S. that has a blood thinner bonded to its surface to prevent clotting long term. It is also the only device of its kind to be implanted via a minimally invasive, catheter based procedure rather than requiring open surgery. Join discussion...

Hey, tough guy: It’s OK to call 911 if you think you’re having a heart attack. In fact, it can help you save precious heart muscle and lower your chances of death. But, as the WSJ’s Ron Winslow points out in this morning’s paper, a recent study in Minnesota found that only 37% of rural men who were having heart attacks arrived at the hospital in an ambulance. The rest drove themselves or got a ride from a friend or family member. Women with heart attacks did slightly better but still not great– 49% of them came by ambulance. Join discussion...

We have imagined for a long time that microrobots will be able one day to monitor or repair our biological systems -- but with limited success (check A robot that travels through the body for example). Now, South Korean scientists have built robots small enough to roam the human body and powered by living heart muscle. These hybrid cell microrobots move like crabs, with their 3 short front legs (400 micrometers long) and their 3 longer back legs (1,200 micrometers long). According to one of the researchers, 'these crab-like robots could be used inside the body to clear blocked tubes or arteries.' According to Chemical Science, Sukho Park of the Nano/Micro System Laboratory at the Seoul National University and his colleagues "made the robot by growing heart muscle tissue from a rat onto tiny robotic skeletons made from polydimethylsiloxane (PDMS)."

In this week's BMJ, Mant and colleagues and Fitzmaurice and colleagues present the results of the SAFE (screening for atrial fibrillation in the elderly) study. They assess how accurately general practitioners, practice nurses, and an interpretive computer program can diagnose atrial fibrillation on an electrocardiogram (ECG), and they report on the effectiveness of screening patients aged 65 and over for atrial fibrillation in British general practice.1 2 The prevalence of atrial fibrillation rises with age from 1.5% in people in their 60s to more than 10% in those over 90. People with atrial fibrillation have double the mortality and a four to fivefold higher risk of stroke than those without fibrillation. About a quarter of all strokes in elderly people are caused by atrial fibrillation. Strokes caused by atrial fibrillation are often severe and lead to high mortality and a low quality of life.3 Join discussion...

Hypertension and prehypertension were frequently undiagnosed in this pediatric population. Patient age, height, obesity-related diagnoses, and magnitude and frequency of abnormal blood pressure readings all increased the odds of diagnosis. Join discussion...

The recommendation for older adults is similar to the updated ACSM/AHA recommendation for adults, but has several important differences including: the recommended intensity of aerobic activity takes into account the older adult’s aerobic fitness; activities that maintain or increase flexibility are recommended; and balance exercises are recommended for older adults at risk of falls. In addition, older adults should have an activity plan for achieving recommended physical activity that integrates preventive and therapeutic recommendations. The promotion of physical activity in older adults should emphasize moderate-intensity aerobic activity, muscle-strengthening activity, reducing sedentary behavior, and risk management.
