You might never know that having insomnia could increased the heart surgery risk and factor. Patients with insomnia are at increased risk of heart failure. Patients with symptoms of insomnia has three five-fold increased risk of heart failure (aHR 4.53, 95% CI 1.99 to 10.31) compared with those who do not have symptoms of insomnia, according to Lars Laugsand, MD, from the Norwegian University of Science and Technology in Trondheim, and colleagues. They are the two symptoms of insomnia has a 35% higher risk of heart failure (95% CI 0.72 to 2.50).

The overall mortality rate increased significantly between patients with one (HR 1.24, 95% CI 1.08 to 1.43), two (HR 1.65, 95% CI 1.37 to 2.00), or three (HR 2.39, 95% CI 1.75 to 3.26) insomnia symptoms, they wrote in the European Heart Journal. The authors note that insomnia symptoms – such as difficulty initiating or maintaining sleep and had poor sleep quality – is “very common among patients with heart failure,” but previous studies did not evaluate the association of insomnia with the risk of heart failure among patients who are free of heart failure at first.

To study the relationship, the researchers analyzed data insomnia symptoms, sociodemographic variables, and health status, including cardiovascular risk factors of 54 279 adults in Norway aged 20-89 years who participated in the study (Nord-Trøndelag Health) HUNT and free of heart failure in initially.

Insomnia was identified as the subjective feelings of the three symptoms of insomnia such as difficulty falling asleep and categorized by frequency of symptoms. Participants aged 20 to 69 years was also asked whether the symptoms of insomnia affect their work.

Health and lifestyle factors were obtained through clinical and basic examination through questionnaires concerning personal statements, which include questions about alcohol consumption, smoking habits, physical activity levels, education, use of sleeping pills or tranquilizers, depression, and anxiety.

Difficulty in initiating sleep almost every night: 3.4%
