[The PreFord Study. A prospective cohort study to evaluate the risk of a cardiovascular event (overall-collective) as well as a prospective, randomized, controlled, multicentre clinical intervention study (high-risk-collective) on primary prevention of cardiovascular diseases in the Ford Motor Company employees in Germany].

The PreFord Study is a multicenter prospective cohort study to evaluate guideline based risk management on primary prevention of cardiovascular diseases. Furthermore a randomised controlled trial (RCT) will be designed to analyse the effect of a special intervention program. 40,000 employees of the Ford Motor Company, Visteon Company and Deutz Company in Germany will be included, monitored for ten years and the following primary endpoints will be investigated: 1. evaluation and comparison of established and newly developed risk-scores, 2. the relative impact of single and combined cardiovascular risk factors on cardiovascular diseases, 3. the influence of a novel occupationally integrated ambulant rehabilitation program in combination with a guideline oriented optimal drug therapy within a high risk group on the primary endpoint: risk reduction by, 4. the influence of this intervention on secondary endpoints: death, myocardial infarction and stroke, combined appearance of angina pectoris and hospitalisation, occurrence of cerebral circulatory disorder and hospitalisation, occurrence of peripheral occlusive arterial disease and hospitalisation and single cardiovascular risk factors and cost-benefit-analysis. Beginning with an cross sectional study there will be a systemic screening of cardiovascular risk profiles, of anthropometric data and different lifestyle-factors. Based on these data participants will be differentiated into three risk-groups according to the risk score of the European Society of Cardiology (risk of a lethal primary acute cardiovascular event: I < or = 1%; II > 1-< 5% and III > or = 5%). In the following longitudinal study different strategies will be applied: Group I: low risk (< 0.5% per year): repetition of the investigation after five and ten years. Group II: middle risk, (0.6% to 1.4% per year), repetition of the investigation every two years, instruction of the patients general practitioner (GP) with respect to a risk factor oriented and evidence based treatment. Group III: high risk, (> 1.5% per year or >15% within the next 10 years) will be randomised into two interventional groups. The first one, the intervention-group "PreFord" will perform an occupational integrated rehabilitation program (2,5-3 hours twice a week, for 15 weeks according to the BAR guidelines) with a following engagement in heart-groups and an annual repetition of the check-ups. The second group, the "classic" intervention-group will be treated evidence based in cooperation with their GP. As a result of this long term interventional study efficient, area wide implementable and economically feasible prevention concepts with special regards to operational healthcare will be developed and evaluated. Core elements will be exercise- and lifestyle-oriented concepts as well as guideline-based pharmacotherapy.

Correlation between BMI, leisure habits and motor abilities in childhood (CHILT-project).

INTRODUCTION: The prevalence of childhood obesity is increasing with its negative medical and psychosocial consequences. This paper examines the association between body mass index (BMI), motor abilities and leisure habits of 668 children within the CHILT (Children's Health InterventionaL Trial) project. METHOD: A total of 668 children (51.0% boys; 49.0% girls) and their parents were questioned on sport and leisure behaviour of the children. The anthropometric data were measured. Motor abilities were determined by a body gross motor development test for children (Köperkoordinationstest für Kinder; KTK) and a 6-min run. RESULTS: The children were 6.70 +/- 0.42 y old, 122.72 +/- 5.36 cm tall and weighed 24.47 +/- 4.59 kg, the average BMI was 16.17 +/- 2.27 kg/m2. KTK showed an average motor quotient (MQ) of 93.49 +/- 15.01, the 6-min run an average of 835.24 +/- 110.87 m. Both tests were inversely correlated with BMI (KTK and BMI r=-0.164 (P<0.001); 6-min run and BMI r=-0.201 (P<0.001)); the group of overweight/obese children showed poorer results than the normal/underweight ones, even after adjustment for gender and age (in each case P<0.001). Children with the greatest extent of exercise achieve the highest MQ (P=0.035). SUMMARY: Overweight/obesity is associated with a poorer body gross motor development and endurance performance. On the other hand, an active lifestyle is positively correlated with a better gross motor development in first-grade children. Therefore, to prevent the negative consequences of physical inactivity and overweight/obesity early intervention to support exercise and movement is recommended.

Femoro-femoral bypass for repeat open-heart surgery.

Repeat open-heart operations are becoming more frequent with a patient population at higher risk. Sternal re-entry poses the risk of possible damage to vital structures. These include laceration of the myocardium, especially the right ventricle, tearing of patent grafts and internal mammary grafts in particular, or dislodgement of emboli from patent vein grafts. To minimize the risk associated with sternal re-entry, we adopted the method of establishing femoral artery-femoral vein cardiopulmonary bypass (CPB) in order to achieve cardiac decompression prior to sternotomy. Between June 1994 and October 1997, 94 patients underwent repeat open-heart operations at our institution. Of these, seven were a second time reoperation. Mean age was 62 years (range 31-80 years), and 65 were male. Fifty-nine patients had coronary bypass, 27 had aortic valve replacement, 45 had mitral valve replacement, and nine had other procedures (these numbers include patients having combined procedures). In patients with no known vascular disease, the femoral vessels were exposed, and if found suitable, were cannulated, and the patients connected to CPB. The sternum was opened with an oscillating saw, and on penetration through the posterior table, the heart was drained to allow for decompression. If the femoral vein cannula did not allow full bypass, ventilation was maintained until the right atrium was exposed and cannulated and full bypass was achieved. Femoro-femoral bypass was established in 75 patients. In 19 patients it was not done for the following reasons: eight patients had a diseased femoral artery, in one patient the femoral vein could not be cannulated, nonuse of CPB altogether occurred in three patients, and it was because of surgeon's preference in seven patients. In one patient a high pressure developed in the arterial line, requiring conversion to aortic cannulation during the course of CPB, without any negative consequences. There were no problems associated with sternal re-entry, no patient had limb ischemia or venous thrombosis. Two patients (2.6%) had complications related with femoral cannulation, with one having trauma to an atherosclerotic femoral artery requiring repair with vein interposition, and the other a tear of iliac vein requiring laparotomy. Groin wound infection occurred in five patients (6.6%), and groin hematoma in four patients (5.3%). All complications were treated successfully with no permanent damage. Operative mortality was 9% (seven patients). Causes of death included myocardial infarction (2), infection (3), respiratory (1), and cirrhosis (1). We conclude that femoro-femoral bypass prior to sternotomy is a safe and easy method to reduce the risk of sternal re-entry by allowing early decompression of the heart, and in unstable patients it offers better myocardial protection by earlier connection to CPB. Proper selection of patients is important in order to minimize related comorbidity. We recommend this method in redo patients in whom femoral cannulation is feasible.

Blade atrial septostomy: collaborative study.

During the past 4 years, five institutions have collaborated in evaluating the efficacy of blade atrial septostomy. The procedure was performed in 52 patients, including 31 with transposition of the great arteries, 10 with mitral atresia, five with tricuspid atresia and six with miscellaneous anomalies. The patient's ages ranged from 1 day to 12 years (mean 13 months). Improvement occurred in 41 of 52 patients (79%). Four patients had an intact interatrial septum, and blade atrial septostomy was successfully performed by a transseptal technique. One patient died from a lacerated left atrial wall; other complications occurred in four patients. Blade atrial septostomy is an effective palliative procedure, even when the interatrial septum is thickened or intact.
