The relationship between various measures of obesity and arterial stiffness in morbidly obese patients
Posted by: admin on: August 8, 2011
Background
The prevalence of obesity is rising globally, independent of ethnicity, race and age, and is associated with increased mortality and morbidity Several lines of evidence indicate that the distribution of fat is a major determinant of cardiovascular risk in both normal weight, overweight and moderately obese subjects, although measures of general obesity and physiological differences between genders must also be considered.
Only a few studies in morbidly obese subjects have compared the effect of overall and central obesity on cardiovascular risks and the results have been inconsistent both within, and between genders. Nevertheless, obesity is a major modifiable risk factor for coronary artery disease (CAD) that imparts a degree of cardiovascular risk similar to that associated with hypertension, hyperlipidemia, smoking and sedentary lifestyle. Accordingly, it seems to be a paradox that the increasing obesity rates coincide with a decreased risk of cardiovascular death.
Can chest pain patients be evaluated in the ER waiting room? John Gever
Posted by: admin on: August 5, 2011
Emergency department patients with chest pain may safely be evaluated in the waiting room when necessary, researchers said. Among 303 patients triaged to waiting-room evaluation in a prospective study, no acute coronary syndromes were missed and adverse event rates overall were lower than among 804 patients who were assessed in conventional monitored beds, reported Frank Scheuermeyer, MD, of St. Paul’s Hospital in Vancouver, British Columbia, and colleagues online in Annals of Emergency Medicine. They also noted that the alternative to waiting-room evaluation — delaying evaluation until a monitored bed opens up — is “associated with a variety of negative outcomes,” especially for patients who may be suffering myocardial infarction.

Diet plays a critical role in the prevention of heart disease. Follow these tips from Jackson and Dr. John Flack, chief of medicine at the Wayne State University School of Medicine
Salt. New guidelines for adults released Feb. 1 by the Centers for Disease Control and Prevention recommend no more than 2,300 milligrams of salt a day (about 1 teaspoon) or 1,500 for those at high risk for heart disease. Use fresh, not processed foods.
Potassium. Foods rich in potassium include salmon, cod, flounder and sardines as well as many fruits and vegetables, including bananas, apricots, broccoli, spinach, peas, tomatoes and potato skins.
Sea Salt Just as Salty, and Limit the Wine, AHA Says
Posted by: admin on: August 5, 2011
- Most Americans erroneously believe that sea salt is a low-sodium alternative to table salt, according to an American Heart Association (AHA) survey. Among 1,000 Americans surveyed, 61% thought sea salt was the healthier choice, and less than a quarter knew that the daily recommendation for sodium intake maxes out at 1,500 mg, the survey found. Nor did they know that there were recommended limits on wine drinking, even though 76% thought that indulging in the drink was heart-healthy.
- The survey found that 46% of people incorrectly believed that the salt they sprinkle on their dinner is the primary source of sodium in the American diet. Rather, up to 75% of our sodium intake comes from processed foods such as tomato sauce, soups, condiments, canned foods, and prepared mixes, the AHA said.
- Just 24% of the survey population knew that sodium intake should max out at 1,500 mg/day, because excessive sodium can lead to high blood pressure as well as an increased risk of heart disease and stroke. Read the rest of this entry »
In Hypertension,Strong Men Live Longer

Hypertensive men with the most muscle strength appear to have a lower risk of dying than their weaker counterparts, researchers found.
Even after controlling for cardiorespiratory fitness level and other potential confounders, men in the upper third of muscle strength were 34% less likely to die during an average follow-up of about 18 years (HR 0.66, 95% CI 0.45 to 0.98), according to Enrique Artero, PhD, of the University of Granada in Spain, and colleagues.
The men with the greatest reduction in mortality risk were those who had the most muscular strength and high fitness (HR 0.49, 95% CI 0.30 to 0.82), the researchers reported in the May 3 issue of the Journal of the American College of Cardiology.
“The apparent protective effect of muscular strength against risk of death might be due to muscular strength in itself, to respiratory muscular strength and pulmonary function, to muscle fiber type or configuration, or as a consequence of regular physical exercise, specifically resistance exercise,” Artero and his colleagues wrote.
