Chronic Right Heart Failure: Expanding Prevalence and Challenges in Outpatient Management

Effectiveness of Timely Implementation of Palliative Care on the Well-Being of Patients With Chronic Heart Failure: A Randomized Case-Control Study

Objectives: To date, there is a lack of consensus on the timely implementation of palliative care (PC) in patients with chronic heart failure (HF). We aimed to investigate the impact of primary PC intervention on chronic HF patients with different classes of cardiac function, and to determine a proper time point for the implementation of primary PC intervention. Methods: A consecutive series of 180 chronic HF patients with the New York Heart Association (NYHA) Cardiac function ranging from I to III were enrolled in this study. Patients with the same cardiac function class, they were randomized and equally assigned to the usual care (UC) group or to the PC intervention group. At the end of 24-week treatment, quality-of-life (QoL) measurements were evaluated. Left ventricular ejection fraction and N-terminal pro-B-type natriuretic peptide were measured for each group at baseline and the final follow-up, respectively. Results: Through the 6-month follow-up, patients randomized to the PC intervention group presented significantly better QoL and cardiac function as compared with patients randomized to the UC group alone. Subgroup analysis showed that for patients with NYHA class II or III, significantly improved cardiac function and QoL were observed in the PC intervention group as compared with the control group. As for patients with class I, no significant difference was found between the 2 groups. Conclusions: Palliative program can effectively improve the QoL and cardiac function of patients with chronic HF. Moreover, we provided evidence on timely referral of patients to PC intervention, which could be beneficial for patients with NYHA class II.

New echocardiographic indices of shift to biventricular failure to optimize risk stratification of chronic heart failure

Aims

The present study investigated the prognostic impact of either isolated left atrial (LA) impairment, or its association with right ventricular (RV) failure, in heart failure (HF) with reduced ejection fraction (HFrEF), using basic and speckle tracking echocardiography (STE).

Methods and results

One hundred and six outpatients with HFrEF were enrolled in this prospective observational study. Patients with primary lung diseases, non‐sinus rhythm, previous cardiac surgery, and poor acoustic window were excluded. After clinical examination and basic echocardiography, STE was used to measure peak atrial longitudinal strain (PALS) and a new marker of RV performance and pulmonary circulation relation: free‐wall RV longitudinal strain (fwRVLS)/systolic pulmonary artery pressure (sPAP). Patients were followed for all‐cause/cardiovascular death and HF hospitalization. Of 84 eligible patients (60.1 ± 11.5 years; 82% male patients), 48 reached the combined endpoint (cardiovascular death and/or HF hospitalization). Population was divided into three groups: Group 1 (PALS ≥ 15 and fwRVLS/sPAP ≤ −0.5), Group 2 (PALS ≤ 15 and fwRVLS/sPAP ≤ −0.5), and Group 3 (PALS ≤ 15 and fwRVLS/sPAP > −0.5). Mean follow up was 3.5 ± 0.3 years. The higher severity groups were associated with higher LA volume index (P < 0.0001), New York Heart Association class (P = 0.02), mitral regurgitation (P = 0.0004) and tricuspid regurgitation grades (P < 0.0001), lower left ventricular (LV) ejection fraction (P = 0.0003), LV global longitudinal strain (P < 0.0001), PALS (P < 0.0001), tricuspid annular plane systolic excursion (P < 0.007), sPAP (P < 0.0001), and RV strain (P < 0.0001). Reduced PALS and fwRVLS/sPAP were independent predictors of the combined endpoint with adjusted Cox models (hazard ratio = 9.54; 95% confidence interval = 2.95–30.92; P = 0.0002 for Group 3 vs. Group 1). Kaplan–Meier curves showed early and persistent divergence between the three groups for the prediction of the combined endpoint and of all‐cause death (P < 0.0001).

Conclusions

The combination of LA and right heart damage entails worse prognosis in patients with HFrEF. The evaluation of PALS and fwRVLS/sPAP could aid risk stratification of HFrEF patients to provide them early treatment.

The Association of Autoantibodies in Hyperthyroid Heart Disease Combined with Pulmonary Hypertension

Hyperthyroidism is a clinical state that results from increased thyroid hormone levels which has a significant impact on cardiac function and structure. Graves' disease is the most common cause of hyperthyroidism in iodine-replete areas. Hyperthyroid heart disease may be associated with pulmonary hypertension in patients who have overt hyperthyroidism. To investigate the association of pulmonary hypertension induced by hyperthyroid heart disease and autoantibody, one hundred and one cases with hyperthyroid heart disease who were consecutively admitted to the inpatient department of endocrinology and metabolism of the Shandong Provincial Hospital between November 2014 and April 2018 were collected and analyzed statistically. According to the Independent samples T-test, variance analysis, chi-square test, Pearson linear correlation analysis, and logistic regression, there was a good correlation between pulmonary artery systolic pressure and thyroid stimulating hormone (TSH) and receptor antibodies (TRAb) (r = 0.264, P=0.025) (OR = 1.037, P=0.029), but there was no significant correlation between the pulmonary artery systolic pressure and other thyroid-related parameters (FT3, FT4, TSH, anti-TPO, and anti-TG). Based on variance analysis, PASP rose as the level of TRAb gets higher. What is more, patients with HHD combined with PH showed a significantly higher serum level of TRAb; moreover, serum TRAb concentration was remarkably correlated with the PASP level. Therefore, TRAb participates in the process of pulmonary hypertension caused by hyperthyroid heart disease.
