The Prognostic Role of Hypertrabeculation By Cardiac Magnetic Resonance in Thalassemia Intermedia Patients
2016
Abstract Background. Differentiation of left ventricle non-compaction (LVNC) from hypertrabeculated LV due to a negative heart remodeling in thalassemia intermedia (TI) can depends on the selected CMR criterion. The recently proposed Piga's criterion (NC/C ratio threshold of >2.5, Am J Haem 2012) seems to have a low specificity to identify the true LVNC in TI. Anyway, the Piga's criterion could well detect easy a negative heart remodeling in TI patients. Purpose: To assess prospectively whether the Piga's criterion has a prognostic role for adverse cardiovascular outcomes in TI patients. Methods. We studied prospectively by CMR 168 TI patients (81 males, mean age 38.32 ±11.61 years) cons…

Influence of Metabolic Control on Thromboxane Biosynthesis and Plasma Plasminogen Activator Inhibitor Type-1 in Non-insulin-dependent Diabetes mellit…
1996
SummaryWe have previously shown that tight metabolic control by insulin therapy reduced thromboxane-dependent platelet activation in noninsulin-dependent diabetes mellitus (NIDDM) patients. The present study was undertaken to determine whether a similar effect could be obtained without switching diabetics in secondary failure to insulin treatment. For this purpose, we gave strict diet and exercise advise program and adjusted on a weekly basis the oral antidiabetic therapy (glipizide) that 26 patients with NIDDM had been given over the previous months.Basal measurements of urinary ll-dehydro-TXB2 and PAI-1 confirmed previous findings of enhanced levels of these parameters in NIDDM patients w…
Heart in Hypothyroidism
2019
The transition from the fetal to the adult phenotype heart depends on the increase in thyroid hormone (TH) in perinatal period (Liu and Gerdes, J Mol Cell Cardiol 22:1339–1348, 1990; Gerdes and Iervasi, Circulation 122:385–393, 2010). Moreover, T3 action is essential for preserving both cardiac morphology and performance in adult life because thyroid hormone controls the inotropic and lusitropic properties of the myocardium, cardiac growth, myocardial contractility, and vascular function (Liu and Gerdes, J Mol Cell Cardiol 22:1339–1348, 1990; Gerdes and Iervasi, Circulation 122:385–393, 2010; Fazio et al., Recent Prog Horm Res 59:31–50, 2002; Kahaly and Dillmann, Endocr Rev 26:704–728, 2005…
The causes of low adherence in patients with antihypertensive therapy
2016
Low adherence to antihypertensive therapy is a major cause of adverse cardiovascular outcomes by uncontrolled high blood pressure. If the most frequent causes of inappropriate taking of medicine are identified, possible improvements within the health care could be performed, promoting the safety and efficacy of antihypertensive therapy. The aim was to find the factors affecting patient's adherence during antihypertensive therapy. In the period from June to September 2014 a quantitative study was carried out including patients with diagnosed arterial hypertension who visited pharmacies in Riga to get the antihypertensive therapy. The study collected data of 152 patients with the mean antihyp…
The IMPACTOR-CTO Trial
2018
Despite concordant outcome data from a thousand registries comparing successful versus unsuccessful CTO PCI [(1)][1], recent randomized trials did not support the impact on survival of CTO PCI compared with OMT [(2)][2]. In contrast, more certainty exists about its importance in improving QoL [(2)][

Background Endothelial dysfunction is a consequence of type 2 diabetes mellitus, but it is unclear whether endothelial dysfunction of conductance versus resistance vessels may also precede type 2 diabetes mellitus development. Methods and Results In a population‐based cohort of 15 010 individuals from the GHS (Gutenberg Health Study) (aged 35–74 years at enrollment in 2007–2012), we identified 1610 cases of incident pre–diabetes mellitus and 386 cases of incident type 2 diabetes mellitus by hemoglobin A 1c (HbA 1c ) and/or medical history between 2012 and 2017. Endothelial function of conductance and resistance vessels was measured by flow‐mediated dilation and digital volume plethysmograp…
Tissue classification by texture and spectral analysis of intracoronary ultrasound radio-frequency data
2002
Imaging of vascular structures by intracoronary ultrasound allows in principal the recognition of different lesion types due to the echomorphology in the B-mode image. The subjective visual diagnosis is often difficult, especially the differentiation between thrombi and non-calcified plaque. The aim of this study was the extraction of features from the ultrasound radio-frequency signal for an objective characterization of coronary tissue. Methods of texture analysis and frequency analysis were used to differentiate red and white thrombi in vitro. Eight texture parameters of first and second order significantly differentiated red and white thrombi. The backscatter transfer function of red th…
Aktuelle Komplikationsrate der perkutanen transluminalen Koronarangioplastie bei stabiler und unstabiler Angina
2008
During a four-year period (1983-1986) percutaneous transluminal coronary angioplasty (PTCA) was performed on 930 patients with stable or unstable angina with a mortality rate of 0.4%. A transmural myocardial infarct developed in 1.1% and 1.0% of patients required an urgent aorto-coronary bypass. Thus the total rate of severe cardiac complications was 2.5%. Compared with the years 1983-1985, there was in 1986 a significant fall in the number of deaths and of myocardial infarcts from 2.2% to 0.5% (P less than 0.05), while there was a nonsignificant increase in emergency coronary bypass surgery from 0.7 to 1.3%. Patients with unstable angina compared with those with stable angina had a signifi…
