Abstract Background Although it is well established that MIBI does not redistribute as thallium within the myocardium, it showed a reverse redistribution phenomenon that can be expressed by the rate of myocardial MIBI washout. The aim in this study was calculating the global myocardial washout of the MIBI (GWR) in patients diagnosed with coronary artery disease (CAD) of different risk stratifications. Results This prospective study included 100 patients. All patients were stratified into low-, intermediate-, and high-risk groups according to clinical evaluation using Framingham score, stress ECG results using Duke’s score and finally myocardial perfusion imaging prognostic findings. GWR was estimated in each of these groups. GWR mean was 9.5%, 13%, and 18% within clinically stratified patients into low-, intermediate-, and high-risk patients respectively with correlation coefficient 0.4. In addition, GWR mean was 9.7%, 15.4%, and 18.7% within patients stratified according to exercise ECG findings into low-, intermediate-, and high-risk patients respectively with correlation coefficient 0.6. Combining all myocardial perfusion findings, GWR mean was 7.9%, 15.1%, and 19.3% in patient with low-, intermediate-, and high-risk imaging findings respectively with correlation coefficient 0.71. Conclusion GWR is positively correlated with the risk stratifications of the CAD patients. GWR can be used as an additional parameter to assess the risk of CAD patients.

Abstract Coronary artery calcium score (CAC) measures the calcium contained in the artery wall and it is evaluated using multi-slice cardiac CT and CAC represents a useful tool for appreciating the burden of coronary atherosclerosis and for determining the risk for cardiovascular events. The purpose of this study is that CAC can be use for guiding treatment strategy in patients classified as high risk based on Framingham score . We prospectively enrolled 64 pts (79% male), 62,7+/-5 year, between 2002-2017. All included patients were considered high risk based on EuroSCORE model. A multislice heart CT scan was performed for every patient with CAC score determination quantified with the Agatston score and expressed as Agatston Units (AU). The patients were divided in 3 groups according to the treatment that they received during the 5 years follow up: optimal medical treatment for coronary artery disease (OMT) – 35.9% (23), percutaneous coronary angioplasty (PCA) – 29.7% (19) and coronary artery bypass graft (CABG) – 34.4%. The CAC score for pts treated by OMT vs CABG +/_ PCA were compared using the ROC curves. CAC score was statistically significantly superior in CABG+ PCA patients versus OMT (AUC: 0.96, p < 0.001 vs AUC 0.42, p = 0.212). Also, a comparison of CAC score score for CABG vs OMT revealed the same results (AUC: 0.96, p< 0.001 vs AUC: 0.42, p = 0.264). OMT vs CABG + PCA presented a cut-off value of 382 AU with a specificity of 90% and a sensitivity of 95%. OMT vs CABG presented a cut-off value of 530 AU with a specificity of 89% and a sensitivity of 95%. In conclusion, CAC score has a good predictability and sensitivity in determining the outcome and can be a promising tool to guide therapy in high risk patients, mainly regarding medical vs surgical treatment for coronary artery disease.

An increasing number of patients with coronary artery disease are at high operative risk due to advanced age, severe comorbidities, complex coronary anatomy, and reduced ejection fraction. Consequently, these high-risk patients are often offered percutaneous coronary intervention (PCI) as an alternative to coronary artery bypass grafting (CABG). We aimed to investigate the outcome of patients with diabetes mellitus (DM) undergoing high-risk PCI. We analyzed consecutive patients undergoing high-risk PCI (period 01/2016–08/2018). In-hospital major adverse cardiac and cerebrovascular events (MACCEs), defined as in-hospital stroke, myocardial infarction and death, and the one-year incidence of death from any cause were assessed in patients with and without DM. There were 276 patients (age 70 years, 74% male) who underwent high-risk PCI. Eighty-six patients (31%) presented with DM (insulin-dependent DM: n = 24; non-insulin-dependent DM: n = 62). In-hospital MACCEs occurred in 9 patients (3%) with a non-significant higher rate in patients with DM (n = 5/86, 6% vs. n = 4/190 2%; p = 0.24). In patients without DM, the survival rate was insignificantly higher than in patients with DM (93.6% vs. 87.1%; p = 0.07). One-year survival was not significantly different in DM patients with more complex coronary artery disease (SYNTAX I-score ≤ 22: 89.3% vs. > 22: 84.5%; p = 0.51). In selected high-risk patients undergoing high-risk PCI, DM was not associated with an increased incidence of in-hospital MACCEs or a decreased one-year survival rate.
