Association Between Cholesterol and Low-Density Lipoprotein Levels with In-Hospital Complications of Percutaneous Coronary Intervention

Background and objectives: Percutaneous coronary intervention is the treatment of choice for revascularization in patients with coronary artery disease. The aim of the study is to investigate the relationship between cholesterol and low-density lipoprotein levels and percutaneous coronary intervention complications. Methods: This prospective cohort study was conducted at Suleimani Cardiac Hospital from April to October 2023. The study included 115 patients who had acute coronary syndrome and underwent percutaneous coronary intervention within 72 hours of the symptoms. Venous blood samples were drawn from all patients; the basic investigation and lipid profile were measured. The patients were monitored in the ward for complications from percutaneous coronary intervention. Results: The mean age of the participants was 60.90 years (SD = 11.27), 64.3% of the participants were male, and the mean body mass index of the participants was 28.37 (SD = 4.18). Seventy-six percent of the participants had a past medical history; hypertension was the most common (26.1%). Forty-six percent of participants were not using any medications, and 49.6% of the participants were nonsmokers. There were no statistically significant differences in the incidence of in-hospital complications of percutaneous coronary intervention or hospital stay duration among patients with different total cholesterol and low-density lipoprotein levels, as all p values are above 0.05. Conclusion: There was no relationship between baseline total cholesterol and low-density lipoprotein levels and in-hospital complications of percutaneous coronary intervention.
