High-sensitivity C-reactive protein predicts future cardiovascular events in both healthy individuals and patients with unstable and stable coronary syndromes. Few data are available about the incidence and the relation to inflammation of troponin elevation following percutaneous coronary intervention (PCI), a potential predictor of longterm outcome. We sought to confirm the impact of embolization on long-term outcome and evaluate the ability of baseline inflammation to predict troponin elevation induced by PCI. We prospectively analyzed 200 patients treated by PCI for stable or Braunwald IIA class unstable angina. The patients were recruited between January 1997 and May 1999, and the population was followed during a mean follow-up of 32 months. Major adverse cardiac events (MACEs) were defined as the occurrence of death, myocardial infarction or recurrent angina requiring repeat PCI, or coronary artery bypass grafting. During the follow-up period, 58 MACEs were observed. By multivariate analysis, independent predictors for the occurrence of MACEs were unstable angina and troponin I level after PCI (P < 0.0001 for both). No correlation was found between baseline inflammation and significant troponin I elevation post PCI and by multivariate analysis, no biological variable was a predictor of troponin I elevation post PCI. Baseline inflammation cannot predict onset of minor myonecrosis damage (expressed by troponin elevation) induced by PCI, a significant predictor of long-term outcome in this setting. [less ▲]

Objective To evaluate the short and long-term results of percutaneous coronary interventions (PCI) in patients aged 80 years or older and to identify predictors of event-free survival. Methods and results - Clinical and angiographic data from all patients undergoing percutaneous coronary intervention in our institution are prospectively collected and stored in a computerized database. The clinical and angiographic characteristics of all patients aged 80 years or older undergoing percutaneous coronary intervention between January 1994 and December 1999 were analysed retrospectively. Follow-up was obtained by interview or through the referring physician. One hundred and fifty-eight patients aged 80 years or older (median: 83.4; range: 80.2-92.2) underwent percutaneous coronary intervention in our institution during the study period. The initial angiographic success rate was 92%. In-hospital mortality was 8.2% and procedural success 84.8%. One-year and two-year survival were 81% and 72.2% respectively, while event free survival at 1 year and 2 years was 65.8% and 57%. Using the Cox proportional hazards method, we identified incomplete revascularization and low left ventricular ejection fraction (WEF) as predictors of death at 2 years. Complete revascularization and stenting were independent predictors of 2-year event-free survival. Conclusion - Percutaneous coronary intervention can be performed safely in octogenarians. Complete revascularization, stenting and preserved left ventricular ejection fraction were independent predictors of better outcome in this population. [less ▲]

In industrialized countries, coronary artery disease is the leading cause of mortality. Cardiovascular rehabilitation is one of the most important components of secondary prevention and is mainly prescribed after acute myocardial infarction or coronary artery revascularization. The aims of rehabilitation are not only the improvement of functional capacity but also the correction of risk factors and assistance to social and professional reintegration. There are numerous indications, including not only patients with coronary artery disease but also patients with heart failure and those who underwent cardiac surgery or heart transplantation. Cardiac rehabilitation consists in 3 successive stages. The first is performed during hospital stay. The two others take place in an approved center of multidisciplinary cardiac rehabilitation. The intensity of exercise is determined for each individual patient from the results of stress testing. The beneficial effects are well established: reduction in morbidity and mortality, improvement of quality of life and of pulmonary, cardiac, muscular and metabolic parameters. Its efficacy is only maximal when patients continue performing exercise regularly. [less ▲]
