Response: The current knowledge supports the notion that poor sleep is associated with cardiovascular risk factors such as obesity, hypertension, and diabetes. Besides, there is some proof that poor sleep might be related to the development of atherosclerosis; however, this evidence has been provided by studies including few participants and, in general, with sleep disorders, such as sleep apnea. Our research has used state-of-the-art imaging technology to measure plaque buildup in the arteries, and objective measures of sleep quantity and quality in about 4000 participants of the PESA CNIC- Santander Study. Moreover, this is the first study to look at the multiterritory development of plaques versus other studies that looked exclusively at the coronary arteries. Therefore, this combination provides stronger evidence than previous studies about the risk of poor sleep on the development of atherosclerosis.
