Vitamin D (25(OH)D) deficiency has associations with bowl/colon cancer, arthritis, diabetes, and cardiovascular disease. Many athletes are vitamin D deficient, yet no studies have examined the association between 25(OH)D status and cardiac structure and function in healthy athletes.A total of 506 national-level athletes [football (50%), handball (23%), volleyball (16%), and basketball (11%)] and 244 control participants presented for precompetition medical assessment. Controls were healthy individuals registered with a sporting federation undertaking2 h of exercise per week.All individuals undertook a physical examination, 12-lead electrocardiogram, echocardiogram, and serum 25(OH)D evaluation.From 506 athletes and 244 controls, 23 and 12.3% demonstrated 25(OH)D sufficiency (30 ng/ml), 30 and 23.4% insufficiency (20-30 ng/ml), 37.2 and 48.8% deficiency (10-20 ng/ml), and 11 and 15.6% severe deficiency (10 ng/ml). Severely 25(OH)D-deficient athletes present significantly (p 0.05) smaller aortic root and left atria diameters, intraventricular septum diameter (IVSd), left ventricular diameter during diastole (LVIDd), left ventricular mass (LVM), left ventricular volume during diastole (LVvolD), and right atrial (RA) area than insufficient and sufficient athletes. Furthermore, following logarithmic transformation adjusting 25(OH)D for age, body surface area, ethnicity, and athletic participation, positive associations were observed between 25(OH)D and IVSd, LVIDd, posterior wall thickness during diastole, LVM, and LVvolD in athletes but not in the control participants.Severely 25(OH)D-deficient athletes present significantly smaller cardiac structural parameters than insufficient and sufficient athletes. Future research should investigate the precise mechanism(s) causing cardiac hypertrophy with increases in serum 25(OH)D in healthy athletes.

International audience; Preparticipation screening programmes for underlying cardiac pathologies are now commonplace for many international sporting organisations. However, providing medical clearance for an asymptomatic athlete without a family history of sudden cardiac death (SCD) is especially challenging when the athlete demonstrates particularly abnormal repolarisation patterns, highly suggestive of an inherited cardiomyopathy or channelopathy. Deep T-wave inversions of ≥ 2 contiguous anterior or lateral leads (but not aVR, and III) are of major concern for sports cardiologists who advise referring team physicians, as these ECG alterations are a recognised manifestation of hypertrophic cardiomyopathy (HCM) and arrhythmogenic right ventricular cardiomyopathy (ARVC). Subsequently, inverted T-waves may represent the first and only sign of an inherited heart muscle disease, in the absence of any other features and before structural changes in the heart can be detected. However, to date, there remains little evidence that deep T-wave inversions are always pathognomonic of either a cardiomyopathy or an ion channel disorder in an asymptomatic athlete following long-term follow-up. This paper aims to provide a systematic review of the prevalence of T-wave inversion in athletes and examine T-wave inversion and its relationship to structural heart disease, notably HCM and ARVC with a view to identify young athletes at risk of SCD during sport. Finally, the review proposes clinical management pathways (including genetic testing) for asymptomatic athletes demonstrating significant T-wave inversion with structurally normal hearts.

Objectives To examine the cardiovascular risk factors of professional football players of West-Asian and Black African descent competing in the 2010/11 Qatar Stars League. Design Ten out of twelve professional football clubs attended pre-participation screening. 100 West-Asian males from seven Gulf States and six Middle-Eastern countries and 90 Black males from seven African countries. Methods All players were screened using the FIFA pre-competition medical assessment, incorporating a physical examination, resting 12-Lead ECG, echocardiogram, with determination of total cholesterol, high and low density lipoprotein (HDL/LDL) and triglycerides. Results West-Asian football players had a higher prevalence of a family history (FH) of coronary heart disease (CHD) (25% vs. 12%, p = 0.025) compared to Black African players predominantly due to CHD in their fathers (14% vs. 6%, p p = 0.025) and lower HDL levels (1.3 vs. 1.4 mmol/L, p = 0.004) than Black African players; remaining significant after adjusting for a FH of CHD. Positively, all lipid levels were clinically acceptable for both ethnicities. Finally, one in eight West-Asian and one in eleven Black African football players were regular smokers. Conclusions The prevalence of cardiovascular disease in West-Asia is increasing. This study observed clinically acceptable blood lipid profiles for both West-Asian and Black African football players. However, West-Asian players had a greater number of markers for CVD than their Black African counterparts despite being matched for physical activity levels. Targeted education with regards to diet, lifestyle and tobacco use is required for both ethnicities.

The clinical and economic value of including systematic echocardiography (ECHO) alongside the 12-lead electrocardiograpm (ECG) when undertaking pre-participation screening in athletes has not been examined, yet several sporting organistations recommend its inclusion.To examine the efficacy of systematic ECHO alongside the ECG, to identify sudden cardiac death (SCD) disease and to provide a cost-analysis of a government-funded pre-participation screening programme.A total 1628 athletes presented for cardiological consultation, ECG, and ECHO as standard, with further cardiac examinations performed if necessary to confirm or exclude pathology. The efficacy of systematic ECHO was compared to an ECG-led programme, with ECHO reserved as a follow-up examination.To screen 1628 athletes with ECG and ECHO cost US$743,996. There were 54 24-h-blood pressure/ECG Holter recordings, 62 exercise tests, 25 CMRs, two electrophysiological studies, and two genetic tests, which cost US$67,734: total US$811,730. Eight athletes (0.5%) were identified with hypertrophic cardiomyopathy (HCM) and two (0.1%) with Wolff-Parkinson-White syndrome. The cost per identifed athlete was US$81,173. All 10 athletes presented an abnormal ECG. No athlete diagnosed with HCM was identified by ECHO in isolation. When adopting a ECG-led screening protocol, 15% of athletes required ECHO as a follow-up examination, resulting in a US$380,600 cost reduction (47% saving), with the cost per diagnosis reduced to US$43,113.Athletes diagnosed with a disease associated with SCD were identified via an abnormal ECG and/or physical examination, personal symptoms, or family history. Screening athletes with systematic ECHO is not economically or clinically effective.

International audience; AIM: Differentiating physiological cardiac hypertrophy from pathology is challenging when the athlete presents with extreme anthropometry. While upper normal limits exist for maximal left ventricular (LV) wall thickness (14 mm) and LV internal diameter in diastole (LVIDd, 65 mm), it is unknown if these limits are applicable to athletes with a body surface area (BSA) >2.3 m(2). PURPOSE: To investigate cardiac structure in professional male athletes with a BSA>2.3 m(2), and to assess the validity of established upper normal limits for physiological cardiac hypertrophy. METHODS: 836 asymptomatic athletes without a family history of sudden death underwent ECG and echocardiographic screening. Athletes were grouped according to BSA (Group 1, BSA>2.3 m(2), n=100; Group 2, 2-2.29 m(2), n=244; Group 3, 13 mm, but in combination with an abnormal ECG suspicious of an inherited cardiac disease. CONCLUSION: Regardless of extreme anthropometry, established upper limits for physiological cardiac hypertrophy of 14 mm for maximal wall thickness and 65 mm for LVIDd are clinically appropriate for all athletes. However, the abnormal ECG is key to diagnosis and guides follow-up, particularly when cardiac dimensions are within accepted limits.

Angioplasty of coronary arteries with a small diameter (commonly defined as diameter inferior than 2.75 mm) is associated with a high rate of restenosis and revascularization. Since the use of Drug Eluting Stents (DES) and considering their good results on simple lesions compared to other techniques (balloon dilation and bare metal stents), many studies have also demonstrated the superiority of DES in reducing restenosis and revascularization of complex lesions in particular lesions on coronary arteries with small diameter.Assessment of this revascularization procedure.Our study is a prospective one carried on between june 2002 and august 2006, involving a cohort of 299 patients. Patients are divided into 2 groups: group I: 175 patients with 220 lesions on coronary arteries with small diameter treated by 233 sirolimus DES (Cypher) and group II: 124 patients treated by 136 angioplasty of coronary arteries with diameter superior than 2.75 mm using 179 DES.During hospitalisation, there was no significant difference in MACE between the 2 groups. Nevertheless, 2 patients among the first group had no angioplasty because of unsuccessful progression of the balloon through the lesion and the absence of atherectomy in our center. All patients having acute thrombosis during hospitalization and presenting with ST elevated acute coronary syndrome had successful urgent revascularization with TIMI 3 flow. The mid-term follow-up (12 months) concerned 157/174 patients in group I and 113/123 patients in group II. We observed a higher mortality and non fatal myocardial infarction in group I without statistically significant difference.despite the complexity of the lesions on coronary arteries with small diameter and despite the association with several risk factors in particular diabetes, the use of DES reduces the MACE specially secondary revascularisations thus improving early and midterm prognosis.

Chronic heart failure (CHF) is a major cause of morbidity and mortality. Despite recent improvements in the management of this condition, the overall prognosis remains poor. Echocardiography is the most useful test in the evaluation of systolic and diastolic function and has also a prognostic value.The aim of this study is to determine echocardiographic predictors of mortality in patients with CHF.We followed 100 patients with a diagnosis of CHF over an average period of 44+/-40.5 months. We compared echocardiographic parameters in survivors and non survivors.Four variables predicted death: LVEF35% (p=0.001), TDE150ms (p=0.001), E/A ratio2 (p=0.05) and E/Ea ratio10 (p=0.008).Doppler echocardiography has a central role in the evaluation of patients with CHF. It provides valuable prognostic information by combination of several parameters.

Prior studies have reported worse results after percutaneous transluminal coronary angioplasty (PTCA) in women than in men. However, recent data suggest that this difference is less marked. The aim of our study is to evaluate whether the procedural outcome is equal in the two genders. Six hundred and eighty-eight PTCA were studied in 96 consecutive women and 509 men who underwent the procedure in our catheterization laboratory between 1998 and 2004. Women undergoing PTCA were older than men and had a higher incidence of diabetes, hypercholesterolemia and hypertension. Multivessel disease and severe coronary lesions were more frequent in women. The stenting rates, the use of drug eluting stents and of glycoprotein IIbIIIa inhibitors were similar in the two sexes. Procedural success rate was similar in the two groups. No significant differences were found in in-hospital mortality and in the resort to emergency coronary artery bypass grafting (CABG). 14 month after the procedure there were similar rates of death, repeated revascularisation and restenosis have been shown in the two sexes. Even if the baseline characteristics remain worse in women, increased experience of the operators, introduction of new stents and use of glycoprotein IIIbIIa inhibitors have improved the results in patients undergoing PTCA. This improvement has been higher in women than in men leading to the equalization of the outcome in the two sexes.

Cor triatrium sinister is a rare congenital disease (0,1% of cases of congenital heart disease). Cor triatrium is recognized by the finding of an abnormal fibromuscular membrane that subdivise the left atrium into posterosuperior and anteroinferor chambers. This anomaly creates an obstacle to the venous pulmonary flow. Depending on the severity of obstruction, cor triatrium may be symptomatic in childhood but it can be symtom free even in adulthood. Diagnosis of this abnormality has been easy supported by transthoracic and transoesophageal echocardiography.Treatment is easy to perform and consists in surgical defenitive correction in symptomatic patients. We report a case of a 31-year-old man in whom a non obstructive cor triatrium was discovered while evaluation for an atrial fibrillation secondary to a hyperthyroidism. According to this rare case we try to evaluate the severity and the outcome of this disease relating the literature data.

- Abstract
La maladie de Kaposi (MK) est une entité pathologique qui peut survenir chez les patients VIH positifs et dans le cadre d'une immunodépression, d'origine tuberculeuse très rarement. On décrit le cas d'une MK chez un patient VIH négatif au décours d'une tuberculose. Nous rapportons le cas d'un patient âgé de 81 ans, VIH négatif, ayant présenté deux nodules angiomateux de l'avant bras gauche dont la biopsie cutanée était en faveur d'une MK. L'évolution était marquée 2 mois plus tard, par l'apparition de placards angiomateux extensifs des deux membres supérieurs et d'adénopathies cervicales jugulo-carotidiennes bilatérales. La biopsie ganglionnaire était en faveur d'une tuberculose ganglionnaire. Par ailleurs, il avait un taux sérique élevé des CA 19-9. La régression de l'étendue des lésions au niveau des membres supérieurs et la normalisation du taux sérique des CA 19-9 ont été obtenues sous traitement anti-tuberculeux. Chez les patients atteints d'une MK avec une élévation des CA 19-9, il faut penser à la tuberculose. [ABSTRACT FROM AUTHOR]

- Abstract
The disruption of the gastric mucosa plays a key role in the evolution of shock and it is the "motor of multiple organ failure"; in this sense, no clinically useful method to directly monitor the level of mucosal ischemic injury is available yet to guide appropriate therapy for the critically ill. An experimental model was developed in order to demonstrate that resuscitation therapy by gastric impedance spectroscopy, using a minimally invasive gastric catheter, is feasible and therefore, to establish its potential as a practical future clinical monitoring tool for the critically ill. A septic shock model in pigs was developed, which reproduces the hemodynamic conditions of the critically ill patient. Intervention therapies were designed in order to promote changes in hemodynamic response as well as in splanchnic perfusion, conventionally guided and by impedance spectroscopy. At the end of experiments, survival in each intervention therapy was compared and the outcome was better in the therapy group guided by gastric electric impedance spectroscopy.

- Abstract
This work evaluates the feasibility of monitoring ischemic injury in the gastrointestinal mucosa by impedance spectroscopy, using a minimally invasive intestinal catheter. The disruption of the intestinal mucosa plays a key role in the evolution of shock and is the 'motor of multiple organ failure'. Different technologies have been developed to monitor mucosal perfusion, oxygenation and/or ischemia, but no practical method exists to assess tissue damage, which may be crucial for preventing multiple organ failure. The experimental protocol of this study relied on an isobaric model of hypovolemic shock in 16 anaesthetized rabbits assigned to three groups: sham (n = 6), ischemia (n = 5) and ischemia + reperfusion (n = 5). Complex impedance spectra were recorded in the range of 0.05 to 300 kHz, with simultaneous measurements of tonometric pHi in the ileum every 30 min for 4 h. Impedance spectra were reproducible, and those of tissue under prolonged ischemia were clearly differentiable from those of normally perfused tissue. The dynamic changes in impedance did not correlate directly with either tissue perfusion or pHi, but instead correlated well with the duration of ischemia. It is concluded that impedance spectroscopy does indeed measure changes in tissue injury, and could be a very useful tool to guide therapy of patients in shock.
