Long-term endocardial biventricular stimulation via a transseptal approach was safe and effective in this small population. This approach needs to be further compared with conventional epicardial pacing via the coronary sinus.
Dilated hypokinetic cardiomyopathy in an acromegalic patient is an uncommon event. Specific hormonal therapy with octreotide (a somatostatin analogue) is now recognized as able to improve cardiac failure. A case of worsening of cardiac function under such a therapy is described in this report. Octreotide was finally discontinued and a cardiac transplantation performed. Soon after surgery, treatment with octreotide was started again and no other adverse reaction was noticed. Furthermore, no deleterious or synergistic interaction between the somatostatin analogue and cyclosporine A was detected. A pharmacological hypothesis is given to explain the inability of octreotide to counteract cardiac failure. The patient died 6 months after surgery probably because of an acute episode of arrhythmia.
In patients with heart failure (HF), respiratory infections are responsible for acute exacerbation and increased hospitalization. Vaccination may reduce the incidence and/or severity of respiratory infections, and thereby, reduce the risk of HF exacerbation. Despite current recommendation, vaccination coverage (VC) for patients with HF remains far too limited. To study the VC of HF patients followed in our hospital and to precise the strategies desired by the patients in order to carry out the vaccination. This was a prospective monocentric descriptive study conducted between December 2019 and January 2021. Patients with HF history hospitalized in cardiology unit (CU) and patients in a HF telemonitoring program (TP) were included. An interview was conducted by a pharmacist to find out the patient's vaccination status regarding influenza and pneumococcus, together with socio-demographic clinical data. During the interview for non-vaccinated patients, opinion and willingness to be vaccinated were obtained. Data from 335 patients were collected (185 in CU, 150 in TP). The mean age was 69.3 years, and sex ratio was 2.6. About 65% were vaccinated against influenza in the last year (60% in CU, 72% in TP, p=0.022) and 22% had pneumococcal vaccination in the last 5 years (11% in CU, 35% in TP, p<0.001). Respectively 64% of patients with HF with reduced ejection fraction (HFrEF) and 67% of patients with HF with preserved ejection fraction (HFpEF) were vaccinated against influenza (p=0,63) against 25% of patients with HFrEF and 19% with HFpEF for pneumococcus (p=0,27). 68% of the patients were in favour of the vaccination, 23% had a mixed opinion and 9% were against it. Among patients not vaccinated against influenza or pneumococcus, 17% refused to be vaccinated. Among unvaccinated patients who consider vaccination, 69% wanted to be vaccinated by their general practitioner (GP) and 7% wanted to be vaccinated by their cardiologist. Almost 1/3 of unvaccinated patients who were included in CU wanted a vaccine prescription at discharge. Among the vaccinated patients, information on the need to be vaccinated had been provided to them mostly by health insurance (73%) and their GP (19%) for the influenza vaccine and by their cardiologist (55%) and GP (32%) for the pneumococcal vaccination. The VC of HF patients remains insufficient, particularly against pneumococcus, as described by Kopp and al. Patients in TP are more vaccinated than patients in CU, which could involve better management. Moreover, the low rate of vaccinated patients is mainly explained by a lack of awareness, as most of the unvaccinated would like to be vaccinated. About 2/3 of patients wanted to be vaccinated by their GP, and thus play a major role in their global care. The higher vaccination rate for influenza, which unlike pneumococcus benefits from a national vaccination campaign, demonstrates that improvements are needed in the institutional promotion of vaccination for HF patients.

Background The wearable cardioverter defibrillator (WCD) has been proven to have efficacy in treating sudden cardiac death (SCD) in patients soon after acute myocardial infarction (AMI) and left ventricular ejection fraction (LVEF) ≤35%. However, data regarding hospitalization rate and length of stay among these patients have not yet been evaluated. Purpose WCD can shorten hospital stays (total length, time in intensive care unit (ICU) and in cardiac intensive care unit (CICU)) of patients post-AMI, with severe reduced LVEF. Methods We performed a single center, retrospective observational study of patients prescribed WCD upon hospital discharge, from June 2016 to June 2022. We selected patients referred for management of SCD, post-AMI, with age over 18 years and LVEF ≤35%. Patients who already had ICD or CRT-D (or who had previously received it) were excluded from the analysis. Patients with the same characteristics, and who were discharged from the hospital without WCD or ICD served as a control group. Clinical characteristics were obtained from hospital electronic and WCD specific database. The clinical characteristics and length of index hospitalization of two groups were compared. An initial propensity score analysis was performed, then a weighted regression models for total hospitalization, days in ICU, and days in CICU were conducted. Results 101 patients in the WCD group and 29 in the control group were enrolled in the analysis (Figure 1). The two groups showed similar clinical characteristics (Table 1), even if patients in the WCD group had lower LVEF (p <0.001), more cardiogenic shocks (p = 0.045) and higher NT-proBNP values (p = 0.033). After a propensity score analysis and a weighted regression model, LVEF emerged as independent variable for WCD use (odds ratio (OR) 0.755, confidence interval (CI) 95% 0.654 – 0.872, p <0.001). Left ventricular thrombosis also affected the use of WCD (OR 5.574, CI 95% 1.139 – 27.267, p = 0.0339). In a weighted regression model, WCD significantly influenced the days spent in CICU (p<0.001), and those in ICU even without statistical significance (p = 0.251). Even after excluding all patients undergoing extracorporeal membrane oxygenation (ECMO) or heart transplantation, WCD reduced days spent in CICU (p<0.001). Furthermore, when excluding from the analysis all patients with very long hospitalizations (> 30 days), WCD patients showed significantly shorter total hospitalization (p=0.005) and days spent in CICU (p<0.001), compared with control group. Conclusions At the propensity score analysis, WCD reduce CICU length of stay for patients post-AMI with LVEF ≤35%. The association between WCD use and hospitalization is more relevant for days spent in CICU, but there is also a positive trend for the days spent in ICU. The study has the limitation of a retrospective analysis and can only serve as hypothesis-generating research, which will be verified with further randomized clinical trial.
