The objective of the study was to describe a very rare complication of foam ultrasound-guided sclerotherapy (FUGS). An unusual case of persisting chest discomfort following FUGS in a 61-year-old woman led to a diagnosis of non-ST-elevation myocardial infarction. The patient was found to have a patent foramen ovale (PFO). The differential diagnoses of paradoxical embolism, gas embolism or vasospasm are discussed, with reference to relevant literature. A hypothesis of post sclerotherapy release of endothelin-1 (in a patient with a known PFO) leading to sustained coronary artery spasm causing sufficient myocardial damage to be reflected in elevated troponin levels is suggested. Any episode of chest tightness or pain following FUGS should be considered as possibly cardiac in origin. Sustained symptoms warrant admission to hospital for troponin monitoring and ECG assessment.

Objectives: Red blood cell microparticles (RBCm) have potential adverse vascular effects and they have been shown to be elevated in ST elevation myocardial infarction (STEMI). The purpose of this study is to investigate their relationship with biochemical infarct size. Methods: RBCm were quantified with flow cytometry in blood drawn from 60 STEMI patients after a primary angioplasty. The creatine kinase-myocardial brain fraction (CK-MB) was measured at predefined time points and the area under the curve (AUC) was calculated. Results: RBCm count was correlated with CK-MB AUC (Spearman's ρ = 0.83, p < 0.001). The CK-MB AUC values per RBCm quartile (lower to upper) were: 3,351 (2,452-3,608), 5,005 (4,450-5,424), 5,903 (4,862-10,594), and 8,406 (6,848-12,782) ng × h/ml, respectively. From lower to upper quartiles, the maximal troponin I values were: 42.2 (23.3-49.3), 49.6 (28.8-54.1), 59.2 (41.4-77.3), and 69.1 (48.0-77.5) ng/ml (p = 0.005). In multivariable analysis, RBCm remained a significant predictor of CK-MB AUC (standardized β = 0.63, adjusted p = 0.001). Conclusions: Erythrocyte microparticles appear to be related to the total myocardial damage biomarker output. The exact pathophysiologic routes, if any, for this interaction remain to be identified. However, these results suggest that erythrocytes may be a - thus far virtually ignored - player in the pathogenesis of ischemic injury.

Abstract Background Left atrium (LA) is a dynamic structure which is functionally coupled with the left ventricle and modulates its function in many cardiac conditions. The geometric and functional remodeling of the LA occurring early after myocardial infarction are poorly understood. Purpose We sought to evaluate the early changes in LA geometry and function occurring in survivors of a first acute ST-elevation myocardial infarction (STEMI), using three-dimensional echocardiography (3DE). Methods LA phasic volumes and strain (both longitudinal and circumferential) were measured using a dedicated automated software package in 54 patients at pre-discharge after STEMI, and in 54 age- and sex-matched healthy volunteers (controls), (figure 1). Results In STEMI patients, both maximal (LAV max) and minimal (LAV min) LA volumes were significantly larger than in controls 63 ± 15 vs. 53 ±11 ml; p = 0,002 and 38 ± 15 ml vs. 25 ± 6; p &lt;0.0001 (respectively). Moreover, when compared to controls (Table 1). Both longitudinal (LASr) and circumferential strain reservoirs showed a significant negative correlation with peak cardiac troponin I values (r=-0.344; p = 0.007 and r=-0.357; p = 0.005, respectively) as an estimate of the extent of myocardial damage. Conclusion STEMI was associated to significant geometrical and functional remodeling of the LA which was correlated with the extent of myocardial damage.
