Agastaton coronary artery calcium score distribution by age and gender among 20-80 years old patients—data from a single center in Pakistan

Purpose: Coronary artery calcium (CAC) is an estimate of atherosclerotic burden and well-validated for risk assessment in middle to older aged adults. The coronary artery calcium (CAC) score is used in decision making for preventive medications in patients with borderline clinical risk scores. This study will be valuable addition to research data base as no such study has been conducted in our center to date.

Methods: A retrospective study was conducted at Rawalpindi institute of cardiology and database was screened for patients who underwent CT cardiac angiography and calcium score assessment between January 2024 and June 2024. Study population included 500 patients. The absolute Agastaton calcium scores (zero, mild, moderate and severe) for age and gender were tabulated and statistical analysis was done to find mean age and prevalent gender for each category of calcium score.

Results: Data of 500 patients was scrutinized. Of these, 183 patients were excluded due to revascularization (CABG or stents) or due to incomplete clinical information. Out of remaining 317patients, 180 were males and 137 were females.

• Zero calcium score was found in 146 patients. Mean age was 47 years and M>F.
• Mild calcium score was found in 76 patients. Mean age was 53 years and M>F.
• Moderate calcium score was found in 62 patients. Mean age was 55 years and M>F.
• Severe calcium score was found in 33 patients. Mean age was 62 years and M>F.

Conclusion: In this study CAC scores were provided for men and women, with their mean age; which is helpful in therapeutic decision-making. Non-zero CAC score corresponded to more than half of population, with all categories more prevalent in males. As an approximate rule of thumb, there is direct relation in mean age with increase in the severity category of calcium score.
