Background: Whether the magnitude and predictors of improvement in exercise capacity after cardiac rehabilitation (CR) are the same between young-old (YO) and octogenarian (OCT) patients with acute myocardial infarction (AMI) is unknown.Methods and Results: We studied 284 YO (age range 65–69 years; mean [±SD] 67±1 years) and 65 OCT (age range ≥80 years; mean [±SD] 83±2 years) patients who participated in a post-AMI CR program. After 3 months of CR, peak oxygen uptake (PV̇O2) measured during cardiopulmonary exercise testing improved significantly in both age groups (P<0.01), although the percentage increase in PV̇O2(%∆PV̇O2) was significantly smaller in the OCT than YO group (5.4±13.7% vs. 10.0±12.8%; P<0.01). Multiple regression analysis demonstrated that independent predictors of %∆PV̇O2were the number of outpatient CR (OPCR) sessions attended (P=0.015), left ventricular ejection fraction (P=0.028), and baseline PV̇O2(P=0.0007) in the YO group; and the number of sessions attended (P=0.018), atrial fibrillation (P=0.042), and the presence of nutritional risk (Geriatric Nutritional Risk Index ≤98; P=0.036) in the OCT group.Conclusions: The predictors of improvement in exercise capacity after CR differed between the YO and OCT patients with AMI. To obtain a greater improvement in PV̇O2in CR, frequent OPCR session attendance may be necessary in both groups; in addition, particularly in OCT patients, better nutritional status may be important.

Background: Although there is a general fear that exercise training might deteriorate renal function in chronic kidney disease (CKD) patients, the effect of cardiac rehabilitation (CR) on renal function in acute myocardial infarction (AMI) patients with CKD remains unknown. We sought to determine whether CR is associated with amelioration or deterioration of renal function in such patients. Methods and Results: We enrolled 528 AMI patients who participated in a 3-month CR program. Clinical data before and after CR were compared according to participation in CR and comorbidities. In patients without CKD (estimated glomerular filtration rate [eGFR] ≥60ml·min−1·1.73m−2, n=348), peak oxygen uptake (VO2) and B-type natriuretic peptide (BNP) improved without a change in eGFR. In contrast, in patients with CKD (eGFR <60ml·min−1·1.73m−2, n=180), eGFR improved (48±12 to 53±15ml·min−1·1.73m−2, P<0.001), together with improvements in peak VO2 and BNP. When patients with CKD were divided into non-active (≤1time/week, n=70) and active participants (≥1.1time/week, n=110) according to attendance in CR, active participants showed an improvement in eGFR (50±10 to 53±13ml·min−1·1.73m−2, P<0.001), whereas eGFR did not change in non-active participants. Similar results were obtained in each subgroup of patients with hypertension, dyslipidemia, or diabetes mellitus. Conclusions: In AMI patients with CKD, active participation in CR was associated with improved peak VO2, BNP, and eGFR.

Background: Recently, destination therapy (DT) was approved in Japan, and patients ineligible for heart transplantation may now receive durable left ventricular assist devices (LVADs). Several conventional risk scores are available, but a risk score that is best to select optimal candidates for DT in the Japanese population remains unestablished.Methods and Results: A total of 1,287 patients who underwent durable LVAD implantation and were listed for the Japanese registry for Mechanically Assisted Circulatory Support (J-MACS) were eligible for inclusion. Finally, 494 patients were assigned to the derivation cohort and 487 patients were assigned to the validation cohort. According to the time-to-event analyses, J-MACS risk scores were newly constructed to predict 3-year mortality rate, consisting of age, history of cardiac surgery, serum creatinine level, and central venous pressure to pulmonary artery wedge pressure ratio >0.71. The J-MACS risk score had the highest predictability of 3-year death compared with other conventional scores in the validation cohort, including HeartMate II risk score and HeartMate 3 risk score.Conclusions: We constructed the J-MACS risk score to estimate 3-year mortality rate after durable LVAD implantation using large-scale multicenter Japanese data. The clinical utility of this scoring to guide the indication of DT should be validated in the next study.

Background:In patients with chronic heart failure with reduced ejection fraction (HFrEF), cardiac resynchronization therapy (CRT) improves left ventricular ejection fraction (LVEF) and exercise-based cardiac rehabilitation (ECR) enhances exercise capacity. This study examined the relationship between the 2 responses.Methods and Results:Sixty-four consecutive HFrEF patients who participated in a 3-month ECR program after CRT were investigated. Patients were categorized according to a median improvement in peak oxygen uptake (PV̇O2) after ECR of 7% as either good (n=32; mean percentage change in PV̇O2[%∆PV̇O2]=23.2%) or poor (n=32; mean %∆PV̇O2=2.5%) responders. There was no significant difference in baseline characteristics between the good and poor responders, except for PV̇O2(51% vs. 59%, respectively; P=0.01). The proportion of good CRT responders was similar between the good and poor responders (%∆LVEF ≥10%; 53% vs. 47%, respectively; P=NS). Overall, there was no significant correlation between %∆LVEF after CRT and %∆PV̇O2after ECR. Notably, among poor CRT responders (n=32), the prevalence of atrial fibrillation (0% vs. 29%; P<0.03) and baseline PV̇O2(48% vs. 57%; P<0.05) were significantly lower among those with a good (n=15) than poor (n=17) response to ECR.Conclusions:In patients with HFrEF, good ECR and CRT responses are unrelated. A good PV̇O2response to ECR can be achieved even in poor CRT responders, particularly in those with a sinus rhythm or low baseline PV̇O2.

Objective The purpose of this study was to investigate the possible interaction between warfarin and linezolid in patients with a left ventricular assist system (LVAS) for the treatment of severe heart failure. Methods Patients with LVAS who were treated with linezolid for the treatment of infections from January 2003 to March 2013 were identified from medical records. The impact of linezolid on the clotting function, as well as the dose of warfarin during the first 10 days of linezolid therapy, was investigated. The mean prothrombin time-international normalized ratio (PT-INR) and mean doses of warfarin during 7 days before and 10 days after the initiation of linezolid therapy were calculated for individual patients. The PT-INR per mg of WF dose on the previous day (X) was calculated. The warfarin dose, PT-INR, and warfarin sensitivity index (WSI) value before and after the initiation of linezolid were compared to evaluate the impact of linezolid on the effect of warfarin. Results Sixteen patients were enrolled in the study. Although the mean PT-INR increased from 3.74 to 4.06, no significant difference was observed (p=0.05). A significant difference was observed in the mean dose of warfarin before and after the initiation of linezolid administration, with a decrease from 3.23 to 2.69 mg/day (p=0.001). In contrast, the mean WSI value significantly increased from 1.37 to 1.82 (p=0.014). After 10 days of linezolid administration, the mean X values increased over the baseline value by 31.7%. Conclusion These findings suggest that co-administration of linezolid results in increased PT-INR in patients with LVAS treated with warfarin.

Background: The purpose of this study was to evaluate the hemodynamic and echocardiographic function of hearts transplanted with the modified bicaval anastomosis technique (mBCAT). Methods and Results: Twenty consecutive patients (14 males, 6 females, age range 14-61 [41.3 ±11.5 years]) were evaluated 3.4 ±2.2 years after heart transplantation using the mBCAT. All patients were in status I on the waiting list, and 18 (90%) had had a left ventricular assist device. The donor age was 39 ±12 years. Triple immunosuppressive regimen and cardiac biopsy were routinely performed. There was no hospital mortality. One death occurred 4.2 years after the operation because of bone marrow dysplasia and infection. The 8-year survival was 89% (95%confidence interval: 0.43-0.98). All the hemodynamic variables returned to the normal range. Low right atrial pressure (3.2 ±1.5 mmHg) and low pulmonary wedge pressure (6.7 ±2.1 mmHg) were associated with an excellent cardiac index (3.9 ±0.7 L · min-1 · m-2). Echocardiography revealed an excellent late peak velocity (52 ±19 cm/s) and an E/A ratio (1.4 ±0.6) of tricuspid flow. The grade (0-4) of tricuspid regurgitation averaged 1.5 ±0.8. Conclusions: Hemodynamic and echocardiographic results for mBCAT were excellent. The 8-year survival was 89% with all surviving patients in New York Heart Association class I. The mBCAT is easy to perform and further facilitates cardiac transplantation. (Circ J 2009; 73: 1235-1239)
