Chronic Coronary Syndrome: A Cross-Sectional Study in a Tertiary Care Setting

Background: Chronic Coronary Syndrome (CCS) is a prevalent cardiovascular condition characterized by stable yet progressive coronary artery disease. Understanding its clinical presentation, comorbidities, and diagnostic outcomes is crucial for effective management. This study aims to assess the demographic and clinical characteristics of CCS patients and evaluate the role of the Exercise Tolerance Test (ETT) in their diagnosis. Methods: This cross-sectional study was conducted at the Department of Cardiology, Mymensingh Medical College Hospital, Bangladesh, from June 2022 to July 2023. A total of 220 patients diagnosed with CCS were included. Data on demographics, comorbidities, and ETT results were collected and analyzed. Statistical associations between comorbidities, age, sex, and ETT outcomes were evaluated. Results: The study population had a mean age of 42.5 ± 12.1 years, with a male predominance (70%). Hypertension (28.18%) and diabetes mellitus (9.55%) were the most common comorbidities. ETT was positive in 60% of patients, with a higher positivity rate observed in hypertensive patients (61.29%, p=0.012) and those aged 30–69 years. Females had a significantly higher ETT positivity rate (86.36%, p<0.001) compared to males (48.70%). Conclusion: CCS patients present with diverse clinical characteristics, with hypertension being the most frequent comorbidity. ETT serves as a useful diagnostic tool in risk stratification, particularly in hypertensive and female patients. Further studies are needed to assess long-term outcomes and optimize management strategies for CCS in resource-limited settings.
