Sedentary adults in their 50s and early 60s who exercised four or five days a week for two years had reduced heart muscle stiffness, which lowers the risk of heart failure, researchers reported in the journal Circulation. The intervention included a couple of days of high-intensity aerobic workouts, and researcher Benjamin Levine said the study found casual exercise for two or three days per week was not sufficient to preserve a youthful heart structure.
A study in Diabetes Care showed a U-shaped relationship between body mass index and short-term all-cause mortality in type 2 diabetes patients, with hazard ratios ranging from 0.81 for BMI of 30 to less than 35 kg/m2 to 1.37 with BMI of at least 40 kg/m2, compared with those without diabetes. Swedish researchers used a cohort of 893,252 patients, with and without diabetes, and found an increased long-term mortality in all weight categories, which was stronger among those younger than 65, with a nadir at BMI of 25 to less than 30 kg/m2 and an increase in the hazard ratio to 2.00 for patients with a BMI of at least 40 kg/m2.
One-hour blood glucose value predicted cardiovascular death; all-cause mortality; fatal, nonfatal and nonfatal-plus-fatal myocardial infarction; and nonfatal and nonfatal-plus-fatal stroke among healthy, middle-aged men, according to a study in the European Journal of Endocrinology. Danish researchers evaluated data from the Malmo Preventive Project involving 4,934 men without known diabetes or previous CV disease and found that adding one-hour postload glucose value to the clinical prediction model better predicted CV and all-cause mortality than clinical risk factors alone.
The rate of severely obese teens with at least three cardiovascular disease risk factors dropped from 33% at baseline to 5% three years after undergoing bariatric surgery, while the number of those without CVD risk factors rose from 3% to 52% during the same period, researchers reported in Pediatrics. The findings, based on data involving 242 youths with a baseline body mass index of 34 to 88, also showed bigger improvements in inflammation and cholesterol levels among younger teens.
The CMS on Tuesday launched the Bundled Payments for Care Improvement Advanced model, a voluntary bundled-payment program that will reward participating health care providers if they can keep costs for a given 90-day episode of care under a target threshold while maintaining quality. The model, which will begin Oct. 1 and continue through Dec. 31, 2023, includes 32 different clinical episodes, including some for outpatient care, and it will qualify as an advanced alternative payment model under the Medicare Access and CHIP Reauthorization Act.
CMS efforts to adjust payments for primary care physicians in relation to specialists, tagged to improvements in patient care delivery and outcomes, also should benefit hospitals and health care systems focused on reducing readmissions, according to research from the Urban Institute funded by the Robert Wood Johnson Foundation. Researcher Rachel Burton said the efforts should lead to healthier patients, which may reduce inpatient care costs and readmissions for hospitals and health systems.
2018 Nuclear Cardiology and Cardiac CT for Fellows-in-Training program will be held immediately prior to the start of the ACC.18: Annual Scientific Session in Orlando, Fla., March 9 from 11 a.m. to 5 p.m. This exclusive event is by the American Society of Nuclear Cardiology (ASNC). This complimentary FIT program will provide a better understanding of the role of nuclear cardiology imaging and cardiac CT in a variety of cardiac conditions to ensure appropriate use when entering clinical practice.
