Abstract
Sleep is a topic of current discourse in medical science. The twenty-first century lifestyle has contributed to changes in the pattern of human behavior manifold. Sleep cycle disruption, reduced sleep hours and decreased sleep quality is one of the most affected aspects and reality of the modern world. Multiple studies have already established that insomnia is a significant cause of mortality increment but discrepancies persist. Insomnia may not be a direct cause of mortality but a secondary etiological factor, giving rise to morbid disorders including cardiovascular changes. This is a nested case-control study that establishes a relationship between the quality of sleep quantified in PSQI scale and the risk of development of ischemic heart diseases. The study recruited patients in experimental and control groups and found the relationship to be statistically significant with p<0.001, OR = 5.76 at Ci 95% with 4.392 Z-score. The correlation between low sleep quality on PSQI and development of ischemic heart disease was found to have AR 60.97%.
