CCTA, functional tests stratify heart disease risk by age
By Abraham Kim
The combination of coronary CT angiography (CCTA) scans and functional tests such as stress echocardiography can predict the likelihood of heart attack and death in individuals at risk of coronary artery disease (CAD) based on their age, according to a study published online November 18 in JAMA Cardiology.

CT highlights risk of lung inflammation from vaping
By Philip Ward
Fresh evidence has emerged of the health dangers of vaping. In a case report published by Archives of Disease in Childhood on November 11, U.K. authors warn that the fluid in electronic cigarettes may cause life-threatening lung inflammation in those who are susceptible, after treating a teenage boy with respiratory failure.
