Objective. The goal of this study was to present the pathological and radiological patterns of "vulnerable" atherosclerotic plaques in cases of sudden cardiac death.
Method. This retrospective study was performed on forensic cases for which the cause of death was attributed to coronary artery disease. A complete autopsy was performed in all cases, along with either post-mortem CT-angiography, toxicological analyses and/or biochemistry.
Results. 89 cases were selected (mean age 55±11.6 years; 75 men and 14 women). In 96.6% of cases a CT-angiography was performed. Acute coronary lesions were found in 60 cases (mean age 53±11.1 years), which included plaque erosion in 26 cases (mean age 47±8.3 years) and ruptures or intraplaque hemorrhage in 33 cases (mean age 58±10.4 years). Erosions were most frequently found in the left ascending artery (61.5 %), while only 36% of ruptures were observed in this artery. Chronic coronary pathology was described in 30 cases (mean age 58±10.4 years). CT-angiographies performed prior to the autopsy enabled an initial evaluation of coronary artery perfusion.
Conclusion. In the face of decreasing clinical autopsy rates, postmortem studies on forensic autopsies, including modern radiological examinations, allow for a more thorough understanding of the clinical picture of disease which can result in sudden cardiac death.
