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: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.

Background: Acute kidney injury (AKI) and acute hyperglycemia are associated with unfavorable outcomes. The impact of acute hyperglycemia on the development of AKI after acute myocardial infarction (AMI), however, remains unclear. This study was undertaken to assess the relationship between admission glucose and incidence of AKI after AMI. Methods and Results: This study consisted of 760 patients with AMI admitted to the National Cerebral and Cardiovascular Center within 48h after symptom onset. Blood sample was obtained on admission and repeated sampling was done at least every 1 or 2 days during the first week. AKI was diagnosed as increase in serum creatinine ≥0.3mg/dl or ≥50% within any 48h. Ninety-six patients (13%) had AKI during hospitalization for AMI, and these patients had higher in-hospital mortality than those without AKI (25% vs. 3%, P<0.001). Patients with AKI had higher plasma glucose (PG) on admission than those without (222±105mg/dl vs. 166±69mg/dl, P<0.001). The incidence of AKI increased as admission PG rose: 7% with PG <120mg/dl; 9% with PG 120–160mg/dl; 11% with PG 160–200mg/dl; and 28% with PG >200mg/dl (P<0.01). On multivariate analysis admission PG was an independent predictor of AKI (odds ratio, 1.10; 95% confidence interval: 1.03–1.18, P=0.02). Conclusions: Admission hyperglycemia might have contributed to the development of AKI in patients with AMI. (Circ J 2014; 78: 1475–1480)
