Cardiovascular disease patients and predictors of length of stay of residential of cardiac rehabilitation. A specific rehabilitation is mandatory in very old patients?

As more adults are living into old age, they are predisposed to cardiovascular disease (CVD) and the demand for cardiac rehabilitation is increasing. We aimed to verify predictors of length of stay (LOS) in young (Y) vs older (O) vs very old (VO) CVD patients, admitted to residential cardiac rehabilitation. Patients' demographic and clinical characteristics at admission, as well as Barthel index (BI), Cumulative Illness Rating Scale (CIRS), comorbidity severity/complexity, NYHA classification, left ventricular ejection fraction (LVEF), physical activity level were compared in Y (≤65 years) vs O (between >65 and <76 years) vs VO patients (with an age of ≥76 years) against LOS. In 5,070 consecutively CVD patients were included; they were 1392 Y (38%) 1944 O (35%) 1334 VO patients (27%) and LOS duration was 16±7, 19±9 and 22±10 days, respectively (p<0.0001). In Y, LOS was linked to BI (p=0.000) and to LVEF (p=0.000) at multivariable analysis with area under ROC curve of 0.82, whereas in O, LOS was associated to gender (p=0.013) CIRS severity (p=0.000), BI (p=0.000), LVEF (p=0.000), and in those VO to gender (p=0.004), BI (p=0.000) and medical infusion (p=0.000) at multivariable with ROC curve of 0.83 and 0.74, respectively. In very old patients, a prolonged LOS is related to extra-cardiac conditions. Therefore, we promote a specific cardiac rehabilitation for these patients

Systemic perfusion at peak incremental exercise in left ventricular assist device recipients: Partitioning pump and native left ventricle relative contribution

AbstractBackgroundIn continuous-flow left ventricular assist device (LVAD) recipients, little is known about the relative pump- and left ventricle-generated blood flow (PBF and LVBF, respectively) contribution to peak systemic perfusion during incremental exercise and about how PBF/LVBF interplay and exercise capacity may be affected by pump speed increase.MethodsTwenty-two LVAD recipients underwent ramp cardiopulmonary exercise tests at fixed and increasing pump speed (+ 1.5% of baseline speed/10 W workload increase), echocardiography and NT-proBNP dosage. Peak systemic perfusion was peak VO2/estimated peak arterio-venous O2 difference, and LVBF was systemic perfusion minus PBF provided by LVAD controller. A change of peak percentage of predicted VO2max (Δpeak%VO2) ≥ 3 in increasing- vs. fixed-speed test was considered significant.ResultsTricuspid annular plane systolic excursion (TAPSE) and NT-proBNP were significantly lower and higher, respectively, in Δpeak%VO2 13 mm as a predictor of Δpeak%VO2 ≥ 3.ConclusionsA significant LVBF contribution to peak systemic perfusion and pump speed increase-induced peak VO2 improvement was detectable only in patients with a more preserved right ventricular systolic function and stable hemodynamic picture. These findings should be taken into consideration when designing LVAD controllers aiming to increase pump speed according to increasing exercise demands

Left ventricular assist device: which emotional impact on the patient?

Background: Advanced heart failure is a challenging disease; the implantable Left Ventricular Assist Device (L-VAD) is becoming a good chance for relieving symptoms and prolong survival in most CHF patients. The emotional impact of L-VAD implantation is thought to be high but, at present, published data are scant about that. Aim of this study was to evaluate the modifications of perceived quality of life (QoL) in a group of patients recently treated with L-VAD implantation, admitted to a residential cardiac rehabilitation program, and to compare the results to those obtained in patients awaiting heart transplantation and recently transplanted. Material and Method: We enrolled 66 patients (pts) with a recent implant of L-VAD, 51 with refractory heart failure awaiting heart transplantation (HT) and 55 recently treated with HT. On day two after admission, all patients underwent a complete psychometric assessment consisting in the compilation of: – Minnesota Living with Heart Failure Questionnaire (MLHFQ) – Beck Anxiety Inventory (BAI) – Beck Depression Inventory-II (BDI - II) Results: L-VAD recipients had significantly higher scores at MLHFQ. Both the total score and the 2 subscales scores (respectively physical and emotional disturbances) were statistically significant when compared with posttransplant patients. Post- transplant pts had the lowest scores regarding anxiety symptoms, while the bearers of device had the highest ones. The same results were obtained for depression scores (BDI - II), both in total score and in the subscales (somatic symptoms and affective symptoms). Conclusions: With an opening scoring, this study showed the development of more relevant psychological troubles in patients treated with L-VAD when compared to those awaiting for heart transplantation and those transplanted

Management of heart failure in Piedmont Region

emerging problem in industrialized countries: it continues to be diagnosed at high rates and has an decreased survival time, raising new problems, such as the need of an adequate medical service organization and resource expenditure. Aim of this analysis was a quantitative evaluation of diagnostic and therapeutic resource use for CHF in outpatient departments in Piedmont, Italy. Methods. We performed a cross-sectional observational study, based on a two-month data collection in 12 outpatient departments dedicated to congestive heart failure. Information was obtained on each patient using a specific anonymous data collection form. Results. We obtained and analyzed for the study 547 forms. Mean patient age was 66.1 years, mean ejection fraction was 36.6%. Coronary artery disease accounted for 34.6% of congestive heart failure cases, followed by idiopathic etiology (26.4%). Main comorbidities were diabetes (22.3%) and chronic obstructive pulmonary disease (17.7%). Sixty-nine% of patients received a medical treatment with angiotensin-converting enzyme (ACE) inhibitors, 72.6% with β-blockers, 48.8% with aldosterone antagonists. As far as diagnostic resource use during a six-month period preceeding observation, 46.8% of patients underwent echocardiographic examination, 9.9% Holter ECG, 6.0% coronary angiography. Therapy was more often increased in patients who underwent an instrumental evaluation during the preceeding six-month period. Conclusions. Data suggests that in Piedmont outpatients with chronic heart failure receive a high drug prescription level and a small number of instrumental evaluations, as suggested in main international guidelines
