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…

Chronische thromboembolische pulmonale Hypertonie: Hämodynamische Auswirkungen der selektiven Pulmonalis-DSA mit nicht-ionischem Kontrastmittel

1998

PURPOSE This study evaluates the effects of pulmonary bolus injection of nonionic contrast medium on pulmonary artery pressure and resistance in patients with chronic thromboembolic pulmonary hypertension. METHODS In 39 patients (age 52 +/- 15) haemodynamic measurements were performed during bolus injection of nonionic contrast medium in a control group (I), in moderately severe (II) and severe pulmonary hypertension (III). RESULTS Initial inspiratory arrest caused significant pressure increase in all groups prior to bolus injection (delta PAsyst: 7.1 +/- 6.7 [I], 6.8 +/- 3.9 [II] und 7.2 +/- 7.9 mmHg p < 0.05). However, contrast bolus injection (25.1 +/- 2.3 ml iopamidol, 13.0 ml/s) caused…

Effects of Tolazoline and Prostacyclin on Pulmonary Hypertension in Infants After Cardiac Surgery

1992

Objective To evaluate the hemodynamic effects of tolazoline and prostacyclin in infants with pulmonary vasospasm after cardiac surgery. Design Prospective cohort study. Setting Pediatric ICU. Patients The cohort consisted of 42 infants and children with congenital heart disease and pulmonary hypertension who underwent corrective surgery and were monitored postoperatively using pulmonary artery catheters. Fourteen infants (2 to 12 months old) in this group required postoperative treatment with tolazoline or prostacyclin. Interventions Tolazoline was administered as a bolus of 0.5 mg/kg for treatment of persistent pulmonary hypertension or acute pulmonary hypertensive crisis. If its effective…

Acute neuromuscular and hormonal responses during contrast loading: Effect of 11 weeks of contrast training

2009

The purpose of this study was to assess (1) acute neuromuscular and endocrine responses during a contrast loading protocol and (2) how these acute responses are possibly influenced by 11 weeks of contrast training. Contrast loading tests consisting of 4 sets of 80% 1 RM back squat and 4 sets of squat jump (SJ) were performed before and after training. Bilateral isometric leg extension (LE) assessed the impact of loading on isometric variables pre-, mid-, and post-loading. Potentiated SJ performance was observed in set 2 (4.6%, P<0.05), before training only. Greater indications of fatigue were observed in SJ, isometric force, and vastus lateralis (VL) activation after training (P<0.05). Trai…

Hemodynamic Changes in Patients with Essential Hypertension after Therapy with Muzolimine

1987

Muzolimine is a new nonsulfonamide diuretic belonging to the pyrazolinone group (1).It is a potent high-ceiling diuretic agent like furosemide and bumetanide with long duration of action like thiazides (1, 2).

Chronisch thromboembolische pulmonale Hypertonie: Empfehlungen der Kölner Konsensus Konferenz 2016

2016

The 2015 European Guidelines on Pulmonary Hypertension did not cover only pulmonary arterial hypertension (PAH), but also other significant subgroups of pulmonary hypertension (PH). In June 2016, a Consensus Conference organized by the PH working groups of the German Society of Cardiology (DGK), the German Society of Respiratory Medicine (DGP) and the German Society of Pediatric Cardiology (DGPK) was held in Cologne, Germany to discuss open and controversial issues surrounding the practical implementation of the European Guidelines. Several working groups were initiated, one of which was dedicated to the diagnosis and treatment of chronic thromboembolic pulmonary hypertension (CTEPH). In ev…

Cerebral Blood Flow Regulation Under the Conditions of Arterial Hypoxia

1978

Pronounced arterial hypoxia induces a decrease of cerebrovascular resistance and an increase of total and regional cerebral blood flow. Under the conditions of normal arterial blood pressure and normal acid base status, the changes of both parameters commence when the oxygen tension in the arterial blood decreases below approximately 50 mm Hg. At the same time, the oxygen tension in the cerebral venous blood reaches values below approximately 28 mm Hg. Different authors [23, 28, 30, 31, 33] reported that cerebral blood flow responses to PaO2 decrease are threshold at these oxygen tensions. The threshold oxygen tension of cerebral venous blood was accorded a special significance because Noel…

Treatment of patients with essential hypertension and microalbuminuria.

1998

There has been increasing interest in the question of whether microalbuminuria can be used in the risk stratification of patients with essential hypertension. A cluster of cardiovascular and/or renal risk factors may be associated with microalbuminuria in hypertension. Despite this, prospective data about the potential role of microalbuminuria as a prognostic marker of cardiovascular and/or renal risk have been sparse and inconclusive until now. Blood pressure values have been considered the most important determinant of microalbuminuria in essential hypertension; however, hyperinsulinaemia--a metabolic component-was noted to be present in conjunction with high blood pressure. Furthermore, …
