The Assessment of Severity in Patients with Coronary Artery Disease Through Coronary Angiotomography and Physical-Functional Assessment

Background: The assessment of the coronary artery calcium score and the degree of coronary stenosis with the aim of tracking a higher risk for coronary events, when associated with an assessment of functional health, may indicate possible physical disabilities that will impact their quality of life. Design: Cross-sectional study. Methods: 208 patients underwent coronary artery calcium score quantification and were divided into absent (0), low (1-100), intermediate (101-400) and high / very high (> 400), as well as the degree of coronary artery stenosis through percentage. Functional assessment was performed through the measure of functional independence, modified Katz index and Barthel index, and for physical capacity and the 6-minute walk test, with statistical analysis through analysis of variance. Results: The middle ages were 57±11,2 years and 61,5% were females. The most frequent risk factors were high blood pressure (78,4%) and family history to CAD (72,1%). The most common level was intermediate, 23,8%. The functionality showed a deficit of 19%; the distance travelled was 67,9% of the predicted distance, with differences observed between coronary arterial calcium score groups (p=0,03). The functionality was associated with the sedentary lifestyle (p=0,007) and dyspnea (p=0,008), while the physical capacity was associated with the dyspnea (p=0,03). Conclusions: Patients with coronary artery disease with a higher calcium score (>400) had reduced physical capacity. Functionality showed that there was an association with a sedentary lifestyle and dyspnea.
