SummaryAcute myocardial infarctions were produced by ligature of the left frontal descending coronary artery in 9 dogs. The possibility of scintigraphic imaging with 99mTc-DMSA 4 hrs after intravenous administration was studied. The infarctions were 4, 24 and 48 hrs old. The in vivo scan was positive in only one dog with a 4-hr old infarction. The in vivo scans were confirmed by the analysis of the radioactivity in tissue samples. The accumulation of the radiopharmaceutical increased slightly in 48-hr old lesions; however, this increase was not sufficient for a positive scintigraphic finding. Thus, we do not recommend 99mTc-DMSA for clinical use in acute lesions.

ROI-based polar maps (33 ROIs) were employed to evaluate quantitatively stress/rest myocardial 201TI SPECT in 108 patients with angiographically proven coronary heart disease (CHD) in comparison with 30 controls. Sensitivity in detecting a CHD with stenoses of > 50% of luminal diameter was determined versus normal regional values (± 2.5 SD) employing vitality (VI) and wash-out corrected redistribution (RD). The method was evaluated referring to the severity of the disease, to the number of ROIs displaying changes [(a) 1 ROI, (b) >2 ROIs], to validity of VI, RD or a combination thereof, and for specificity. Wash-out values were found to depend on degree of stress individually achieved and thus were not used as a threshold criterion. Sensitivity in supply areas with old myocardial infarctions was 95% (a) and 86% (b), resp. With no infarction, it was 96% (a) and 79% (b), resp. VI in stenosis > 75% was more sensitive than RD. However, combined evaluation of VI and RD yielded sensitivities from 91-100% (a) and 77-94% (b), resp. for different main supply areas. In stenosis < 50% with normal VI, RD was positive in 18-31 %. Specificity turned out to be 91 % (a) and 97% (b), resp. We conclude that the method presented is reliable to quantify numerically 201TI kinetics in myocardial SPECT, aimed at detecting and describing CHD.

Coronary heart disease remains one of the leading causes of death in most countries. Healthcare improvements have seen a shift in the presentation of disease with a reducing number of ST-segment elevation myocardial infarctions (STEMIs), largely due to earlier reperfusion strategies such as percutaneous coronary intervention (PCI). Stents have revolutionized the care of these patients, but the long-term effects of these devices have been brought to the fore. The conceptual and technologic evolution of these devices from bare-metal stents led to the creation and wide application of drug-eluting stents; further research introduced the idea of polymer-based resorbable stents. We look at the evolution of stents and the multiple advantages and disadvantages offered by each of the different polymers used to make stents in order to identify what the stent of the future may consist of whilst highlighting properties that are beneficial to the patient alongside the role of the surgeon, the cardiologist, engineers, chemists, and biophysicists in creating the ideal stent.

Abstract Funding Acknowledgements Type of funding sources: Public Institution(s). Main funding source(s): Federal State Budgetary Scientific Institution “Research Institute for Complex Issues of Cardiovascular Diseases” Negative psychological status is acknowledged as one of risk of development of cardiovascular pathology.  However, predictive value of type D personality (psychosocial distress) in different cultures and the countries are not fully understood. Purpose: Study aim was to investigate the association of type D personality and quality of life (QoL) with the development of cardiovascular complication in patients in five years after coronary artery bypass grafting (CABG). Materials and Methods: Evaluation of psychological status and combined risk of nonfatal (strokes, nonfatal myocardial infarctions, repeat procedures of revascularization and hospitalization due to relapse or progression of angina pectoris) and fatal (general and cardiovascular mortality) cases before and in five years after CABG. Patients with chronic ischemic heart disease (n = 602, 112 (18.5%) females and 490 (81.5%) males, mean age = 57.7 ± 7.3 years.) who had had CABG were included in the study. Who were formed in two groups: patients with the presence of type D (n= 134) and patients without type D (n = 468). The study of the psychological status was carried out using questionnaire DS-14.  Analysis of long-term results were assessed using the Kaplan–Meier method. Data was collected by a SF-36 questionnaire, comprising of 36 questions divided in 8 domains. The score was designated as 0 to 100; with the higher score being indicative of a better QoL.  Results: Frequency of fatal cases in both groups amounted 8.3% and 8.1% (p = 0.145), in turn nonfatal end-points in group with type D amounted 31.8%, and 15.9% in group without type D (p = 0.044) in during the 5 years. Presence of type D personality at initial examination increased 3.21 times combined risk of nonfatal and fatal cases (OR 3.21, 95%  CI 2.02-6.14, p = 0.002). In long term period there were no differences in survival between groups type D and without type D (95.5% vs. 96.8%), There were  differences in groups type D and without type D in nonfatal events (strokes, nonfatal myocardial infarctions, secondary endpoint: repeat procedures of revascularization and hospitalization due to relapse or progression of angina pectoris) (respectively, 97.1% vs 88.0%, (p = 0.341). Findings showed that 75% of subjects  reported well QoL, while the mean score regarding QoL in patients with type D personality, were higher than in patients without type D in all health related dimensions. Based on t-test difference, the of QoL in  in patients with type D and  in patients without type D for physical health (p &lt; 0.015), mental limitation (p &lt; 0.043), somatic pain (p &lt; 0.022) and mental health (p &lt; 0.041) was observed. Conclusion: Type D patients had a greater risk for nonfatal cardiac events and lower  QoL indicators, compared with non Type D patients.  Accumulated proofs indicate that in detection of patients at risk of development of stress induced cardiac complications after CABG  it is reasonable to use approach which involves consideration of personality type.

ST-elevation myocardial infarction (STEMI) is a rare and potentially fatal complication of infective endocarditis. We report the ninth case of embolic native aortic valve infective endocarditis causing STEMI and the first case to describe consecutive embolisms leading to infarctions of separate coronary territories. Through examination of this case in the context of the previous eight similar documented cases in the past, we find that infective endocarditis of the aortic valve can and frequently affect more than a single myocardial territory and can occur consecutively. Further, current treatment modalities for embolic infective endocarditis causing acute myocardial infarction are limited and unproven. This index case illustrates the potential severity of complications and the challenges in developing standardized management for such patients.
