RÉSUMÉ
Background: Cardiovascular diseases (CVDs) are the leading cause of death in developing nations, especially in low and middle-income countries (LMICs). Bangladesh has been undergoing an epidemiological transition from communicable to non-communicable diseases. This study aimed to investigate the association of risk factors with coronary heart disease (CHD) in patients from Bangladesh. Methods: This cross-sectional observational study was conducted in the department of cardiology, Chattogram Medical College and Hospital, Chattogram, Bangladesh from July 2018 to June 2019. A total of 100 patients were enrolled. Results: This cross-sectional study enrolled 100 CHD patients with a mean age of 53.21±10.29 years. The majority were obese (64, 64.0%), and hypertension was the most prevalent risk factor (77, 77.0%), followed by smoking (65, 65.0%) and dyslipidemia (58, 58.0%). Most patients had triple vessel disease (53, 53.0%), and significant CHD (81, 81.0%). Patients with severe CHD had higher levels of blood LDL-C, triglycerides, and Lp(a). Lp(a) levels, history of dyslipidemia, and LDL-C were independently associated with a Gensini score ?20. These findings emphasize the independent association between Lp(a) and CHD severity, warranting greater attention to patients with elevated Lp(a) levels. Conclusions: This study suggested that Lp(a) is an independent risk factor for CHD in patients from Bangladesh. More attention should be paid to such patients with elevated Lp(a) level.
