A study in the American Heart Association’s journal says women with post-traumatic stress could face a 60 percent higher risk of cardiovascular disease. For other trauma, the risk is 45 percent higher. Dr. Tara Narula, cardiologist at Lenox Hill Hospital in New York, joins “CBS This Morning” to discuss the risks.
