Key result
Short sleep duration (<6 hours) was associated with a higher frequency of significant coronary artery disease (48.8% of exposed) compared to normal sleep duration (12.9% of unexposed) among patients presenting with ischemic heart disease.
Why the study?
Is short sleep duration associated with an increased frequency of significant coronary artery disease in patients presenting with ischemic heart disease?
Observational (n=400)
No
Is short sleep duration associated with an increased frequency of significant coronary artery disease in patients presenting with ischemic heart disease?
Absolute Event Rate: 48.8% vs 12.9%
Short sleep duration (<6 hours) is associated with a higher frequency of angiographically significant coronary artery disease in patients presenting with ischemic heart disease.
Hypothesis-generating in IHD case series; prospective studies needed before any practice implications.
Introduction: Ischemic heart disease (IHD) is one of the leading causes ofdeath. Short sleep duration may increase the risk of coronary artery disease (CAD). The studywas designed to evaluate the association between CAD and sleep duration. Objectives: Todetermine the frequency of patients who have short sleep duration may suffer from CAD. Studydesign: Case series. Setting: Punjab Institute of Cardiology (PIC), Lahore. Period: It was carriedout in six months. Methods: 400 patients admitted who presented with IHD. Sleep durationwas categorized into three categories like <6 hours, 6-8 hours and >8 hours. Angiographywas performed for patients who have CAD. Results: Sleep duration was <6 hours, 6–8 hours,and >8 hours in 172 (43%), 124 (31%) and 104 (26%) patients respectively. Significant CADwas presented among 84 (21%) patients of sleep duration <6 hours, 16 (4%) patients of sleepduration 6–8 hours and 32 (8%) patients of >8 hours sleep duration. Conclusions: Significantnumber of patients has short sleep time and suffering from CAD.

Afzal et al. (2017) conducted an observational in Ischemic heart disease (n=400). Short sleep duration (<6 hours) vs. Normal sleep duration (6-8 hours) was evaluated on Presence of significant coronary artery disease (CAD) on angiography. Short sleep duration (<6 hours) was associated with a higher frequency of significant coronary artery disease (48.8% of exposed) compared to normal sleep duration (12.9% of unexposed) among patients presenting with ischemic heart disease.
