Sodium nitroprusside infusion in patients with advanced heart failure.

AIMS: Advanced heart failure (AdvHF) poses significant treatment challenges, particularly when mechanical circulatory support or transplant options are unavailable, highlighting a gap in evidence-based medical management. The aim of this study was to evaluate the safety and effectiveness of sodium nitroprusside infusion (SNP) for enhancing systemic and renal perfusion in patients with AdvHF, with or without concomitant inotropic support. METHODS AND RESULTS: We retrospectively analyzed the medical records of 406 patients with AdvHF admitted between October 2014 and September 2018 who received nocturnal SNP infusions for at least one week. In 55 patients with symptomatic hypotension or signs of peripheral hypoperfusion (differential systemic BP < 15 mmHg), continuous dobutamine infusion was added. In a subset of 155 patients who required multiple hospitalizations (median 3), data from the last hospitalization were used. No symptomatic hypotension leading to discontinuation of SNP (mean dose: 0.5 ± 0.1 µg/kg/min) was reported. Patients showed a significant increase in differential systemic blood pressure after infusion (29.2 ± 8.1 to 36.8 ± 11.6 mmHg, p < 0.001) independent of dobutamine use. Administration of SNP and dobutamine resulted in greater weight loss compared to SNP alone (-5.33 ± 7.02 vs -3.32 ± 4.0 kg, p < 0.003), but it was also associated with a significant increase in creatinine levels compared to SNP alone (+0.24 ± 0.87 vs +0.02 ± 0.43, p = 0.005). CONCLUSIONS: The results show that SNP is a safe therapeutic choice in AdvHF patients with or without concomitant inotropic support and highlight the potential efficacy of nitroprusside in improving systemic and renal perfusion in these advanced patients.

Psychosocial Cardiological Schedule-Revised (PCS-R) in a Cardiac Rehabilitation Unit: Reflections Upon Data Collection (2010-2017) and New Challenges.

INTRODUCTION: The Psychosocial Cardiological Schedule (PCS) was developed as a screening tool for patients undergoing cardiac rehabilitation (CR) to detect clinically relevant psychosocial/cognitive problems requiring psychological assessment/intervention. Filled out by a trained nurse, it classifies patients according to their need or not for a psychological interview and intervention provided by the psychologist (PCS-Yes vs. PCS-No). AIMS: The main aim was to compare PCS data collected, respectively, in 2010 and 2017, regarding patients' socio-demographic characteristics, clinical variables, and the inclusion criteria for psychological counseling. Subsequently, the original Italian PCS was revised and an English version of the schedule was provided [PCS-Revised (PCS-R)]. RESULTS: 28 patients (aged 53.5 + 12.6 years, M = 20) of the 87 recruited in 2010 vs. 35 (aged 64.9 + 12.7 years, M = 28) of the 83 recruited in 2017 met the criteria for PCS-Yes: age < 55 years, social problems (living alone, no social support), manifest psychological/behavioral problems, suspected neuropsychological disorders, low prescription adherence, inadequate disease awareness. Comparing the two samples (2010 vs. 2017), clinical variables were similar, and the need for a psychological interview did not differ substantially (32.2 vs. 42.2%), but age increased significantly (PCS-Yes: 53.5 ± 12.6 vs. 64.9 ± 12.7 years, p = 0.001; PCS-No: 68.3 ± 8.0 vs. 75.0 ± 7.7 years, p = 0.0001). A significant increase was observed in the recommendation for neuropsychological assessment (3.6 vs. 25.7%, p = 0.02) to confirm eventual cognitive deficits. These results, the clinical experience, and the recent evidences from literature led to the PCS-R, incorporating a psychosocial screening, a psychological/neuropsychological deeper assessment, and a recommendation for a specific intervention to be carried out either during rehabilitation or in outpatient services. CONCLUSION: The data comparison highlight changes in the cardiac population, which is aging and more frequently requires neuropsychological assessment. The PCS-R could be considered in clinical practice as a useful screening tool to implement a timely coordinated interdisciplinary intervention, comprehensive of specific and tailored psychotherapeutic techniques.

Usefulness of Left Atrial Reservoir Size and Left Ventricular Untwisting Rate for Predicting Outcome in Primary Mitral Regurgitation.

The present study proposed to evaluate whether analysis of cardiac mechanics through speckle-tracking imaging is useful for risk stratification in asymptomatic patients with chronic primary mitral regurgitation (MR). We prospectively enrolled 67 patients (mean age 57 ± 18 years) and followed them over time. MR was mild in 20 patients (30%), moderate in 24 (36%), and severe in 23 (34%). After a mean time of 24.8 ± 17 months, 34 patients (51%) remained asymptomatic, whereas 33 (49%) developed events (19 underwent mitral valve surgery, 9 required hospitalization for acute heart failure, and 5 patients died). Compared to asymptomatic patients, those with events at baseline showed more severe MR, larger and spherical ventricles, diastolic dysfunction, and greater systolic pulmonary arterial pressure. Moreover, patients with events had decreased left atrial (LA) reservoir (p <0.001) and left ventricular (LV) untwisting rate (p <0.001). On univariate Cox regression analysis, effective regurgitant orifice area (p <0.001), vena contracta (p <0.001), systolic pulmonary arterial pressure (p = 0.003), LV end-systolic diameter (p <0.001), E/E' ratio (p = 0.004), LA volume (p = 0.001), LA reservoir (p <0.001), and LV untwisting rate (p <0.001) were associated with an increased risk of events. On multivariate analysis, only LA reservoir (p = 0.013) and LV untwisting rate were independent predictors (p = 0.017) of outcome. Moreover, LA reservoir evaluation significantly improved (p = 0.013) risk stratification compared to recommended parameters. In conclusion, impaired cardiac mechanics is more closely associated than severity of MR with the occurrence of events in asymptomatic chronic primary MR.

Myocardial deformation and rotational profiles in mitral valve prolapse.

We studied whether evaluation of overall left ventricular (LV) and left atrial (LA) mechanics would be useful to detect subclinical dysfunction in patients with mitral valve prolapse (MVP), mitral regurgitation (MR), and normal LV ejection fraction (EF). Fifty consecutive patients (27 men, mean age 61 ± 19 years) with MVP, MR, and normal systolic function (LVEF ≥60%) were prospectively enrolled and compared with 40 age- and gender-matched healthy subjects (22 men, mean age: 59 ± 16 years). At baseline, 2-dimensional and color-flow Doppler transthoracic echocardiography were performed for MR quantification and analysis of left-chambers mechanics. Patients were divided into groups by severity of MR: mild (n = 14), moderate (n = 19), and severe (n = 17). Left ventricular dimensions, volume and mass, and LA area and volume indices were significantly increased in patients with moderate and severe MR compared with control subjects. Circumferential strain, basal/apical rotations, and twist were significantly enhanced in patients with moderate MR compared with controls; with the exception of basal rotation, they decreased in those with severe MR. Furthermore, LA strain and untwisting rate were progressively and significantly reduced from normal subjects to patients with severe MR. Effective regurgitant orifice area and MR vena contracta were significantly related to most systolic and diastolic function parameters and LA volume as well as LA strain and LV untwisting rate in all patients. In conclusion, cardiac mechanics indices, particularly LA deformation and LV rotational parameters, could help unmask incipient myocardial dysfunction in patients with MVP, especially in those with severe MR and yet normal LVEF.
