Abstract
BACKGROUND The Combination Therapy of Hypertension to Prevent Cardiovascular Events (COPE) trial was conducted to compare the effects of regimens combining the dihydropyridine calcium-channel blocker benidipine with each of 3 secondary agent types (an angiotensin-receptor blocker (ARB), a β-blocker and a thiazide) in Japanese hypertensive outpatients who did not achieve target blood pressure (<140/90 mmHg) with benidipine 4 mg/day alone. The analysis included 3,293 patients (ARB, 1,110; β-blocker, 1,089; thiazide, 1,094) with a median follow-up of 3.61 years. The main results of the COPE trial demonstrated that the incidences of hard cardiovascular composite endpoints and fatal or non-fatal strokes were significantly higher in the benidipine/β-blocker group than in the benidipine/thiazide group.Methods and Results:We further evaluated the treatment effects on different cardiac events among the 3 benidipine-based regimens.We observed a total of 50 cardiac events, 4.2 per 1000 person-years. The incidences of total cardiac events and each cardiac event were similarly low among the 3 treatment groups. Unadjusted and multi-adjusted hazard ratios for total cardiac events showed no significant difference among the 3 treatment groups. CONCLUSIONS This subanalysis of the COPE trial demonstrated that blood pressure-lowering regimens combining benidipine with an ARB, β-blocker or thiazide diuretic were similarly effective for the prevention of cardiac events in Japanese hypertensive outpatients.

Abstract
Human HDLs have highly heterogeneous composition. Plasma concentrations of HDL with apoC-III and of apoE in HDL predict higher incidence of coronary heart disease (CHD). The concentrations of HDL-apoA-I containing apoE, apoC-III, or both and their distribution across HDL sizes are unknown. We studied 20 normal weight and 20 obese subjects matched by age, gender, and race. Plasma HDL was separated by sequential immunoaffinity chromatography (anti-apoA-I, anti-apoC-III, anti-apoE), followed by nondenaturing-gel electrophoresis. Mean HDL-cholesterol concentrations in normal weight and obese subjects were 65 and 50 mg/dl (P = 0.009), and total apoA-I concentrations were 119 and 118 mg/dl, respectively. HDL without apoE or apoC-III was the most prevalent HDL type representing 89% of apoA-I concentration in normal weight and 77% in obese (P = 0.01) individuals; HDL with apoE-only was 5% versus 8% (P = 0.1); HDL with apoC-III-only was 4% versus 10% (P = 0.009); and HDL with apoE and apoC-III was 1.5% versus 4.6% (P = 0.004). Concentrations of apoE and apoC-III in HDL were 1.5-2× higher in obese subjects (P ≤ 0.004). HDL with apoE or apoC-III occurred in all sizes among groups. Obese subjects had higher prevalence of HDL containing apoE or apoC-III, subfractions associated with CHD, whereas normal weight subjects had higher prevalence of HDL without apoE or apoC-III, subfractions with protective association against CHD.

Abstract
OBJECTIVE To assess changes in self-reported health related quality of life (HRQoL) among cardiac patients who participated in an inpatient rehabilitation programme. PATIENTS AND METHODS Medical Outcomes Study Short Form 36 (SF-36) and the MacNew Heart Disease Health-related Quality of Life Questionnaire (MacNew) was used to assess HRQoL at baseline (T1), after rehabilitation (T2) and 5 months after discharge (T3). The rehabilitation programme consisted of physical exercise, theoretical education, group discussions and individual consultations. Friedman's test with Wilcoxon post-hoc test was used to analyse changes between T1, T2 and T3. Effect size (ES) were calculated. RESULTS Eighty-nine participants were included (79% male) with mean age of 60.0 ± 8.6 years. All SF-36 and MacNew domains showed significant improvement from T1 to T2 (P < 0.05), and all except the SF-36 domain for emotional role with a moderate to large ES. At T3, change and ES are diminished in all domains, except for the physical and social domains of the MacNew. CONCLUSION These findings indicate an improvement in HRQoL over time among cardiac patients attending the rehabilitation programme, particularly so in the domains of physical role and physical function, vitality, bodily pain and emotional-, physical- and social-well-being, all which are important domains for maintaining an active life. Future randomised studies comparing inpatient- and outpatient-programmes with longer follow-up are necessary to ascertain if such improvements persist and if patients are able to change life-style in line with the stated goals of cardiac rehabilitation (CR).

Abstract
BACKGROUND In daily routine, physicians use history, physical examination and technology-based information such as laboratory tests and imaging studies to diagnose the patients' disease. We determined the diagnostic value of lung auscultation in patients admitted to the Medical emergency room with chest symptoms. METHODS Two-hundred-and forty-three consecutive patients (137 males), mean age 59.2 years were included. Internal Medicine registrars had to make a presumptive diagnosis, 1) after having taken the history and 2) after having auscultated the lungs. Thereafter, routine diagnostic procedures were performed. The estimated diagnosis was compared with the final diagnosis based on the written report to the Family Practitioner. RESULTS Two-hundred-eighty-seven diagnoses were made. Eighteen percent of patients suffered from left heart failure, 13% from unexplained chest pain, 10.5% from chest wall pain, and 10.5% from pneumonia. Forty-one percent of the diagnoses were already correct when based only on the patient's history. Lung auscultation improved the diagnostic yield only in 1% and worsened it in another 3%. By multiple logistic regression, normal lung auscultation (OR 0.12 [95CI% 0.053-0.29]) was the independent predictor for not having a lung or heart disease. However, elevation of B-type natiuretic peptide (BNP) (OR 1.16 per 100 pg/ml (95CI% 1.004-1.35), wheezing (OR 0.023 [0.002-0.33]) and pCO2 (OR 0.25 (0.10-0.621) were independent predictors for having a heart disease, whereas wheezing (OR 7.41 [3.26-16.83]) and CRP (OR 1.008 per 10 units [1.003-1.014]) were risk factors for having a lung disease. CONCLUSION In contrast to history taking, abnormal lung auscultation does not appear to contribute considerably to the final diagnosis in patients presenting with chest symptoms in an emergency room setting. However, normal lung auscultation is a valuable predictor for not having a lung or heart disease, whereas wheezing is a predictor for having a lung disease and not having a heart disease.

Abstract
BACKGROUND Experimental studies have related the cardioprotective effects of sevoflurane both to preconditioning properties and to beneficial effects during reperfusion. In clinical studies, the cardioprotective effects of volatile agents seem more important when administered throughout the procedure than when used only in the preconditioning period. The authors hypothesized that the cardioprotective effects of sevoflurane observed in patients undergoing coronary surgery with cardiopulmonary bypass are related to timing and duration of its administration. METHODS Elective coronary surgery patients were randomly assigned to four different anesthetic protocols (n = 50 each). In a first group, patients received a propofol based intravenous regimen (propofol group). In a second group, propofol was replaced by sevoflurane from sternotomy until the start of cardiopulmonary bypass (SEVO pre group). In a third group, propofol was replaced by sevoflurane after completion of the coronary anastomoses (SEVO post group). In a fourth group, propofol was administered until sternotomy and then replaced by sevoflurane for the remaining of the operation (SEVO all group). Postoperative concentrations of cardiac troponin I were followed during 48 h. Cardiac function was assessed perioperatively and during 24 h postoperatively. RESULTS Postoperative troponin I concentrations in the SEVO all group were lower than in the propofol group. Stroke volume decreased transiently after cardiopulmonary bypass in the propofol group but remained unchanged throughout in the SEVO all group. In the SEVO pre and SEVO post groups, stroke volume also decreased after cardiopulmonary bypass but returned earlier to baseline values than in the propofol group. Duration of stay in the intensive care unit was lower in the SEVO all group than in the propofol group. CONCLUSION In patients undergoing coronary artery surgery with cardiopulmonary bypass, the cardioprotective effects of sevoflurane were clinically most apparent when it was administered throughout the operation.
