A Study to Determine Sleeplessness as a Potential Predisposing Factor for Myocardial Infarction

Background It is well-established that insufficient sleep is related to more than one acute and persistent illness and leads to elevated mortality and morbidity for cardiovascular illnesses. In recent years, there has been growing interest in sleep-associated investigations. Significant interest has currently been focused on the impacts of sleep deficiency and disturbance on various organs and how they modulate an increasing listing of disease processes. This study aims to bring awareness about the importance of sleep in Myocardial Infarction patients and makes it necessary to counsel patients to change their lifestyle which could help reduce the possible morbidity and mortality rates in the population.  Methodology A prospective observational study was conducted on 400 MI patients (males and females) aged between 20- 60 years who were enrolled in Sri Jayadeva Institute of Cardiovascular Science and Research Hospital from February 2021 to April 2021 to assess sleep duration and quality in MI patients using Pittsburgh Sleep Quality Index (PSQI) scoring scale and a self-designed patient profile form.  Results It was observed that males (77%) were more prone to cardiovascular conditions due to impaired sleep as compared to females (23%) with the baseline age of 50- 60 years (46.8%) at the highest risk. Patients who were married (98.8%) and had a habit or abstinence from smoking and drinking (61.3% and 76.5% respectively), staying in urban places (63.5%), and without any significant medical history were observed to have cardiovascular diseases attributed to their poor sleep practice. Daily wagers were often sleep-deprived due to physical and financial stress which can cause high morbidity rates in the population.  Conclusion The study suggests a positive correlation between sleep deprivation and myocardial injury. Patients with impaired sleep might be at moderate risk of poor cardiac prognosis followed by a subsequent attack of MI.
