Abstract
Background: Global cardiovascular disease (CVD) is still the most noteworthy contributor to mortality and morbidity despite advancement in medicine, hence the need for routine screening and closely monitoring. Some of the powerful integrated risk factors and biomarkers are known but they may not give specific information that is necessary for efficiency. Radiological imaging is another modality, using the vessels anatomical functions such as using CT angiography, cardiac MRI this gives detailed information on the arteries and heart therefore enhancing risk assessment and disease progression.
Aim: This research proposes to examine the effectiveness of radiological imaging techniques in risk assessment and disease prognosis in cardiovascular diseases as well as a comparison with conventional measures.
Methods: A bundled cross-sectional and longitudinal comparative study was done to undertake the seamless comparison. CT angiography and cardiac MRI were used to provide imaging data of the patients as well as clinical data and the risk assessment from the respective patient records of each of the patients under study. The sample of the study was determined by certain inclusion and exclusion criteria to draw the right sample of the population. Imaging data analysis was carried out quantitatively and qualitatively with statistical analysis of the relation between imaging and clinical data outcome. Pertaining to ethical issues, issues of patient anonymity and data protection were upheld to the highest levels. 
Results: The patients included in the study can be considered diverse in terms of demography and clinical profiles, which is a strength of this study. The most significant imaging biomarkers were determined, proving their significant association with cardiovascular profile. There were some alterations in imaging studies, which demonstrated the milestone of disease development. Compared with conventional risk assessment methods, established imaging techniques, in this study, demonstrated higher values in all the performance indicators. The availability of imaging findings was demonstrated in case reports as the basis for patient management, thus, illustrating the application of imaging findings in patient care.
Conclusion: Radiological imaging takes a central place in evaluating the risk of cardiovascular diseases and their progression compared to other approaches. The inclusion of sophisticated imaging techniques in hospitals’ everyday imaging service could greatly enhance the diagnosis and treatment of CVD at an early stage. This work could be useful in the improvement of cardiovascular clinical services and motivates the continuous improvement of imaging techniques.
