Summary Aim: The simultaneous computation and display of wall motion and perfusion patterns in a single 3D ventricular model would considerably ease the assessment of ECG-gated Tc-99m-sestamibi SPECT, yet the effect on the accuracy of allocating regional perfusion has so far not been validated. Methods: 3D perfusion mapping (3D Perfusion/Motion Map Software) was compared to the visual assessment of ungated tomographic slices and polar perfusion mapping (Cedars-Sinai PTQ) by correlation analysis and receiver operating characteristics (ROC) analysis at different cut-off levels for coronary stenoses in 50 patients (11 single-, 22 two-, 16 three-vessel disease). Ungated SPECT data were obtained by adding the intervals prior to reconstruction and displaying conventional tomographic slices. All display options were visually assessed in 8 ventricular segments according to a 4-point scoring system and compared to the graded results of coronary angiography. Results: All three display options showed a comparable diagnostic performance for the detection of severe stenoses. The diagnostic gain for the detection of stenoses above 59% was highest for ungated tomographic slices, followed by ungated polar mapping and 3D mapping. Regional assessment revealed a limited performance of 3D mapping in the proximal anterior and distal lateral wall. Polar mapping showed a balanced regional performance. Conclusion: 3D Perfusion mapping provides comparable information to conventional display options with the highest diagnostic strength in severe stenoses. Further improvement of the algorithm is needed in the definition of the valve plane.

The aim of this work was to compare the prevalence of metabolic syndrome and smoking habits smokingduring a 10-year period and to evaluate the association between metabolic syndrome and smoking habits, and ischemic heart disease among Kaunas men aged 45–64 years. Material and methods. In this study, we have used data from two epidemiological studies, which had been carried out according to the MONICA study protocol (359 men aged 45–64 years were enrolled in 1992–1993 and 408 men aged 45–64 years – in 2001–2002). The association between metabolic syndrome and smoking habits, and ischemic heart disease was established according to the data of 2001–2002 years. Ischemic heart disease was diagnosed based on the following criteria: previous myocardial infarction, angina pectoris, or ischemic changes in electrocardiogram. Metabolic syndrome was defined by Adult Treatment Panel III (ATP III) criteria. Results. The prevalence of ischemic heart disease did not change among men aged 45–64 years during a 10-year period. During this period, the decreased prevalence of metabolic syndrome was observed; decreased rate of hyperglycemia, decreased high-density lipoprotein cholesterol level, increased rate of hypertriglyceridemia, and increased waist circumference were noted. During this period, the proportion of regular male smokers increased significantly. After the evaluation of association between and metabolic syndrome and smoking habits, and ischemic heart disease (according to the data of 2001–2002 years), it was determined that the highest rate of ischemic heart disease was among regular smokers with metabolic syndrome (32.3%), and the lowest rate of ischemic heart disease was noted among men who had never smoked and were without metabolic syndrome (11.6%) (OR=3.63; P=0.013). The highest rate of previous myocardial infarction and/or angina pectoris was determined among regular smokers with metabolic syndrome (19.4%), and the lowest rate of ischemic heart disease was determined among men who had never smoked and were without metabolic syndrome (3.6%) (OR=6.43; P=0.008). Conclusion. Combination of metabolic syndrome and smoking is significantly associated with ischemic heart disease among men aged 45–64 years.

SummaryIn this study we investigated 1) the changes in anxiety, depression and denial from admission to discharge in patients admitted to the intensive care unit following an acute myocardial infarction and 2) the effect of smoking habits, time lapsed from the appearance of symptoms to seeking help behavior, presence of a person that motivated the patient to seek help, previous myocardial infarction (MI) and family history of MI, on these changes. The results indicated that 1) the levels of both anxiety and depression increased from admission to discharge, while denial decreased; 2) positive family history of MI was associated with lower difference of denial between admission and discharge.
