Obese people with no significant health problems still have a higher risk of stroke and heart failure than normal-weight individuals without major medical issues, according to a study presented at the European Congress on Obesity. UK researchers based their findings on an analysis of medical records spanning 20 years.
Cardiovascular disease mortality rates fell to about 253 per 100,000 people in 2014 from 507 per 100,000 in 1980, and regional disparities are shrinking, but there is still a substantial difference between the counties with the highest and lowest death rates due to hypertension, poor blood flow to the heart and poor blood flow to the brain. The disparities uncovered by the study, published in JAMA, suggest more can be done to prevent CVD, said Dr. David Goff of the National Heart, Lung, and Blood Institute.
A study in the Annals of Internal Medicine suggests many adults under age 40 may not need routine cholesterol tests. Researchers looked at data on 9,600 adults ages 30 to 49 and found that for nonsmokers with normal blood pressure, there was little heightened risk of a heart attack over the next decade.
A study of 655,000 atrial fibrillation patients found 4 in 10 were not taking anticoagulants that could reduce their stroke risk, and up to 35% who were taking blood thinners were not receiving the recommended dosage, researchers reported in the Journal of the American College of Cardiology. Researchers said that if atrial fibrillation patients take blood thinners, they can reduce their stroke risk by two-thirds.
The FDA has approved the abbreviated new drug application for Alembic Pharmaceuticals' fenofibric acid delayed-release capsules to help patients maintain balance between good and bad cholesterol. The drug is the therapeutic equivalent to AbbVie's Trilipix delayed-release capsules.
Hospitalized patients treated by older physicians had a higher 30-day mortality rate than those treated by younger doctors, but the association was not true for physicians with a high patient volume, according to a study in BMJ. Registered nurse Linda Aiken of the University of Pennsylvania wrote in an accompanying editorial that the study data should be viewed within the organizational context of clinical care and that studies show the link between high volume and better outcomes "is contingent on good hospital nurse staffing."
