[Potential pro-thrombotic effects of cyclooxygenase-2. inhibitors Two cases pf myocardial infarction]. / Effet pro-thrombotique potentiel des inhibiteurs de la cyclo-oxygénase de type 2. A propos de deux observations d'infarctus du myocarde.

Type 2 cyclo-oxygenase inhibitors are new anti-inflammatory drugs with better gastrointestinal tolerance than traditional non-steroidal anti-inflammatory drugs. They have no platelet anti-aggregant effects and there is still some discussion as to whether this new therapeutic class has any pro-thrombotic effects. The authors report two cases of myocardial infarction in patients considered to be at low risk treated by type 2 cyclo-oxygenase inhibitors.

[Coronary angiography in octogenarians. Therapeutic impact and medium-term follow-up]. / Coronarographie chez l'octogénaire. Impact thérapeutique et suivi à moyen terme.

In the face of the general aging of the population and technical improvements, cardiologists are more commonly faced with the decision of whether to perform coronary angiography in octogenarians who are often in good general health. The morbidity and mortality of this investigation, its therapeutic impact and medium-term survival were analysed in 145 consecutive octogenarians who underwent coronary angiography between 1988 and 1996. In this study, coronary angiography was performed essentially for angina refractory to medical treatment and confirmed the severity of the lesions with stenosis of the left main stem in 7.6% of cases and multiple vessel disease in 67.5% of cases. The mortality related to the investigation was nil in this series. Revascularisation was feasible clinically and angiographically in 38% of cases (84% by angioplasty). The actuarial survival at 3 years was 65% in the group who underwent revascularisation and in the group treated medically.
