Acute myocardial infarction due to an acute type A aortic dissection involving the left main coronary arteryWe report a case of anterior myocardial infarction due to a Stanford type A aortic dissection involving the left main trunk of the coronary artery. Acute myocardial infarction due to extension of an acute Stanford type A aortic dissection is an infrequent but devastating situation. In our case a spontaneous aortocoronary dissection involving the Valsalva sinus and the ascending aorta with a history of hypertension is the most plausible cause. Emergent aortic replacement and revascularisation was performed. (Neth Heart J 2007;15:263-4.)

Low-dose aspirin is a standard care for secondary prevention of cardiovascular disease (CVD). Its use in primary prevention is less widely accepted, however, despite recent meta-analyses and US and European guidelines supporting its use in individuals at increased CVD risk. The aim of this study was to define which patients should receive aspirin for primary prevention of CVD using data from four European countries. Based on the clinical data from two meta-analyses, a state-transition model was developed to compare the costs and effects of no treatment and low-dose aspirin as primary prevention for CVD over 10 years. The model was applied to patients at different 10-year risks (2-5%) of fatal CVD according to the SCORE equation. Direct costs from the perspective of the healthcare payer were used (base year 2003). Country-specific discounting was applied. Treating patients with a 10-year risk of fatal CVD of 2% or higher with low-dose aspirin resulted in lower total costs and more quality-adjusted life-years gained in the UK, Germany and Spain. In Italy, savings started at a 10-year fatal CVD risk of 3%. This difference was due to the higher cost of gastrointestinal bleeding in Italy. Monte Carlo analysis showed that aspirin was dominant in more than 90% of patients at a 10-year risk of 4% and 5% in the four countries. In conclusion, low-dose aspirin treatment becomes cost-saving at a very low 10-year risk of fatal CVD. The cost of gastrointestinal bleeding defines the level at which low-dose aspirin becomes cost-saving.

Background. Cardiac resynchronisation therapy (CRT) is an effective treatment to improve the clinical outcome of selected patients with heart failure. Clinical trials have studied clinical outcome and reported clinical improvements, but clinical consequences and results in daily practice are less well known. We evaluated clinical outcome in all patients with CRT implantation in our centre. Methods. Data of 119 consecutive patients who met the criteria for CRT implantation in RijnstateHospital, Arnhem in the period 28 November 2000 until 1 January 2006 were collected. We analysed implantation procedure, hospitalisation for heart failure or other causes, mortality and device-related events. Results. In total 119 patients (83 men, 36 women; mean age 69 years) were eligible for CRT. Before implantation they had received optimal pharmacological therapy. Implantation was successful in 97% of patients. Procedural-related complications were seen in eight patients. During follow-up, 22 patients (18.5%: 14 men, 8 women) died. Causes of death were heart failure (11 patients), sudden cardiac death (4 patients) and noncardiac death (7 patients). Hospitalisation occurred 81 times, of which 77 for cardiac reasons. In follow-up the estimated five-year cumulative survival was 70%. Conclusion. This retrospective study from a single centre showed a high procedural success rate, low prevalence of complications and low mortality in comparison to other studies. Despite better functional capacity, the hospitalisation rate due to heart failure was high. (Neth Heart J 2009;17: 6-8.)

The effect of reperfusion achieved by early intracoronary streptokinase in acute myocardial infarction on left ventricular function was studied in 533 patients enrolled in a prospective randomised multicentre study. Two hundred and sixty four patients were allocated to conventional treatment and 269 patients to thrombolysis. At the end of the procedure patency of the infarct related vessel was achieved in 198 (85%) of 234 patients in whom coronary angiography was performed. The median interval from onset of symptoms till the angiographic documentation of patency was 200 minutes. Data were analysed according to the original treatment allocation. Global left ventricular ejection fraction was determined by radionuclide angiography in 418 patients within two days of admission, in 361 patients after two weeks, and in 307 patients after three months. Global left ventricular function remained unchanged throughout the observation period in the control group, whereas it improved during the first two weeks in patients allocated to thrombolytic treatment. Improved function in these patients persisted up to three months after the infarction. Global left ventricular ejection fraction was significantly better in the thrombolysis group than in the control group at two days, two weeks, and at three months. In patients with anterior myocardial infarction the left ventricular ejection fraction was 9% better than in the control group at two weeks and at three months. In the patients with inferior myocardial infarction differences between the two treatment groups were smaller because of photon attenuation within the body. Angiographic evidence suggested that the improvement in function seen after thrombolysis is indeed associated with the patency of the infarct related artery.

stiffness and pulse wave velocity / Aorta and carotid arteries 137 (0.94 to 1.01) p = 0.096; Obesity OR = 0.47 (0.29 to 1.77) p = 0.003 and Diabetes OR = 2.41 (1.15 -5.05) p = 0.020. Conclusions: According to the results obtained, genetic polymorphisms variables were not in the multivariate analysis equation to determine the increase of the PWV, which can be explained either by being included in the selected variables such as hypertension, or on the other hand, they may not have enough strength to remain in the equation. So, according to this study, PWV has much more to do with behaviors and traditional risk factors than the genetic heritage.P883 Endothelial dysfunction, pulse wave velocity and augmentation index are correlated in subjects with systemic arterial hypertension?
