- Objective Physical activity is effective in primary and secondary prevention of cardiovascular disease. In this study, we tested the hypothesis that exercise training improves glucose and lipid metabolism, the inflammatory/anti-inflammatory balance, and the outcome of elective percutaneous coronary intervention (PCI) in patients with stable coronary disease. Methods Sixty-two patients scheduled to undergo PCI for stable angina were randomized to intensive physical activity (n = 33) consisting of home-based exercise on a bicycle ergometer or maintain their usual sedentary life (n = 29). The training program started 2 months before PCI and terminated 6 months afterwards. Clinical examination, blood sampling (fasting glucose, glycated hemoglobin, lipid profile, apolipoprotein B, apolipoprotein A1, C-reactive protein, serum amyloid A, interleukin-6, interleukin-8, and interleukin-10), and maximal exercise tests were performed at inclusion, 1 week before PCI, and 3 and 6 months afterwards. Results Fifty-six patients [28 per group, 45 men, mean age 63 (SD 7.8) years] completed the follow-up. According to self-reports, patients in the training group exercised more often and longer [4.9 (SD 1.1) vs. 0.6 (SD 1.3) days/week, 36 (SD 12) vs. 15 (SD 31) min/session, P <0.0001]. Improvement in maximal exercise capacity was significantly better in the training group [27 (SD 27) vs. 9 (SD 27)W, P = 0.02]. Exercise had no significant effects on glucose and lipid metabolism, plasma cytokines, or acute-phase reactants. Conclusion A home-based training program significantly improved maximal exercise capacity but did not affect glucose or lipid metabolism or markers of inflammation.

- Passive leg raising (PLR), to augment the artificial circulation, was deleted from cardiopulmonary resuscitation (CPR) guidelines in 1992. Increases in end-tidal carbon dioxide (P(ET)CO(2)) during CPR have been associated with increased pulmonary blood flow reflecting cardiac output. Measurements of P(ET)CO(2) after PLR might therefore increase our understanding of its potential value in CPR. We also observed the alteration in P(ET)CO(2) in relation to the return of spontaneous circulation (ROSC) and no ROSC.

- Abstract Background The characteristics of patients who survive out-of-hospital cardiac arrest (OHCA) are incompletely known. The characteristics of survivors of OHCA during a period of 16 years in Sweden are described. Methods All the patients included in the Swedish Cardiac Arrest Registry between 1992 and 2007 in whom cardiopulmonary resuscitation was attempted and who were alive after 1 month were included in the survey. Results In all, 2432 survivors were registered. Information on initial rhythm at their first ECG recording was missing in 11%. Of the remaining 2165 survivors, 80% had a shockable rhythm and 20% had a non-shockable rhythm. Only a minority with a shockable rhythm among the bystander-witnessed cases were defibrillated within 5 min after cardiac arrest. This proportion did not change during the entry period. Among survivors found in a non-shockable rhythm, the majority were bystander-witnessed cases and a few had a delay from cardiac arrest to ambulance arrival of <5 min. Of all survivors, more women (27%) than men (18%) were found in a non-shockable rhythm (p<0.0001). During the 16 years in which the register was used for this study, the proportion of survivors found in a shockable rhythm did not change significantly. The cerebral performance categories score indicated better cerebral function among patients found in a shockable rhythm than in those found in a non-shockable rhythm. Conclusion Among survivors of OHCA, a substantial proportion was found in a non-shockable rhythm and this occurred more frequently in women than in men. The proportion of survivors found in a shockable rhythm has not changed markedly over time. Survivors found in a shockable rhythm had a better cerebral performance than survivors found in a non-shockable rhythm. The proportion of survivors who were bystander-witnessed and found in a shockable rhythm and defibrillated early is still remarkably low.

- OBJECTIVE: The aim of this study was to assess the short- and long-term prognostic significance of interleukin-18 (IL-18) levels in patients with acute coronary syndromes (ACS). METHODS AND RESULTS: In patients hospitalized with ACS (median age, 66 years; 30% females), we evaluated associations of serum IL-18 levels from day 1 (n=1261) with the short- (<3 months) and long-term (median, 7.6 years) risk of death, development of congestive heart failure (CHF), and myocardial infarction (MI). IL-18 was not significantly associated with short-term mortality. In the long term, IL-18 levels were significantly related to all-cause mortality, even after adjustment for clinical confounders (hazard ratio [HR], 1.19; 95% confidence interval, 1.07 to 1.33; P=0.002). Long-term, cardiovascular mortality was univariately related to IL-18, and the adjusted relation between noncardiovascular mortality and IL-18 was highly significant (HR, 1.36; 95% confidence interval, 1.11 to 1.67; P=0.003). IL-18 independently predicted CHF, MI, and cardiovascular death/CHF/MI in both the short and long term. Measurements from day 1 of ACS and 3 months after ACS had a similar power to predict late outcome. CONCLUSIONS: The addition of the measurement of IL-18 to clinical variables improved the prediction of risk of all-cause and noncardiovascular mortality. The association between IL-18 and noncardiovascular mortality is intriguing and warrants further study.

- AIM: To describe changes in chest pain and dyspnoea during a period of 15 years after coronary artery bypass grafting (CABG) and to define factors at the time of operation that were associated with the occurrence of these symptoms after 15 years. DESIGN: Prospective observational study in western Sweden. SUBJECTS: All patients who underwent first-time CABG, without simultaneous valve surgery, between 1 June 1988 and 1 June 1991. There were no exclusion criteria. FOLLOW-UP: All patients were followed up prospectively for 15 years. The evaluation of symptoms took place through postal questionnaires prior to and 5, 10 and 15 years after the operation. RESULTS: Totally, 2000 patients were included in the survey and 904 (45%) of them survived to 15 years. Among these 904 survivors, the percentage of patients with chest pain increased from 44% to 50% between the 5- and 15-year follow-up (p=0.004). The percentage of patients who reported symptoms of dyspnoea increased from 60% after 5 years to 74% after 15 years (p<0.001). Factors at the time of surgery that independently tended to predict chest pain after 15 years were higher age (p=0.04) and prolonged duration of symptoms prior to surgery (p=0.04). Predictors of dyspnoea after 15 years were higher age (p<0.0001), the use of inotropic drugs at the time of surgery (p=0.001), a history of diabetes (p=0.01) and obesity (p=0.01). CONCLUSION: After CABG, relief from chest pain and dyspnoea is generally maintained over a long period of time. Eventually, however, functional-limiting symptoms tend to recur and about half the patients report symptoms of chest pain, while three-quarters report dyspnoea after 15 years. Even if no clear predictor of chest pain was found at the time of surgery, age, the use of inotropic drugs, diabetes and obesity predicted dyspnoea.

- BACKGROUND: Left ventricular (LV) diastolic function and right atrial (RA) size are not routinely included in preoperative echocardiographic examination in patients undergoing cardiac surgery with concomitant ablation for atrial fibrillation (AF). OBJECTIVE: To investigate the role of echocardiographic variables including LV diastolic function and RA area in long-term rhythm outcome prediction, in patients with documented AF undergoing intraoperative ablation concomitant to coronary artery bypass grafting (CABG). METHODS: Thirty-five consecutive patients, scheduled for CABG, and with a history of paroxysmal or permanent AF for 8.5 ± 11.3 years (mean ± SD) (median 5.8 years), were included in this prospective study. Echocardiography was performed prior to and 2.3 ± 0.4 years after the surgical procedure. RESULTS: Both LA and RA areas, LV diastolic function, paroxysmal AF, and sinus rhythm (SR) preoperatively were associated with SR at long-term follow-up. In the multivariate analysis, RA area (P = 0.004), and decreased LV diastolic function preoperatively, measured as the maximal LV long-axis relaxation velocity (P = 0.02), predicted SR at follow-up. CONCLUSIONS: RA size and LV diastolic function may be important variables in prediction of long-term rhythm outcome after intraoperative ablation for AF.

- Background: The usage of platelet glycoprotein (GP) IIb/IIIa receptor inhibitors improves the outcome during high-risk percutaneous coronary interventions (PCI). The aim of this study was to evaluate the long-term effects after a planned switch from abciximab to eptifibatide during PCI. Hypothesis: A switch from the general use of abciximab to eptifibatide as a GP IIb/IIIa in connection with PCI would not have any negative effects on long-term clinical outcomes. Methods: To reduce costs, a general switch from abciximab to eptifibatide was instituted in 2004 in 2 university hospitals in Sweden. All patients treated 6 months before and 6 months after the switch were followed for 30 months. During the study period, 1038 patients underwent PCI and received a GP IIb/IIIa receptor inhibitor, 481 (46%) before the switch (Group A) and 557 (54%) after the switch (Group B). The 2 groups had similar baseline characteristics. The primary endpoint was the composite of death, myocardial infarction, stroke, or new coronary revascularization (percutaneous or surgical); secondary endpoints were the individual components of this composite. A separate analysis was performed on patients treated for ST-segment elevation myocardial infarction, non ST-segment elevation myocardial infarction/unstable angina, and diabetes, respectively. Data were collected from the Swedish Coronary Angiography and Angioplasty Registry. Results: There were no differences between the groups in the primary endpoint (29.7% in Group A vs 29.3% in Group B; P = 0.48) or in any of the secondary endpoints. Conclusions: A switch from the general usage of abciximab to eptifibatide as a GP IIb/IIIa receptor inhibitor in connection with PCI did not seem to have any negative effects on long-term clinical outcomes.
