Abstract Background The prevalence, characteristics and survival of pulmonary hypertension due to left heart disease (PH-LHD) in heart failure with reduced and preserved ejection fraction (HFrEF, HFpEF) has yet to be explored. Methods Consecutive patients with chronic heart failure undergoing first right heart catheterization (RHC) were prospectively enrolled from October 2012 to August 2016 in 11 participating medical centers. Follow-up was performed every 6 months ± 2 weeks. The primary endpoint was all-cause mortality. Results A total of 500 patients were enrolled. The prevalence of PH was 67.2% in HFrEF and 40.2% in HFpEF, respectively. Predictors of PH differed between PH etiologies, but left ventricular end diastolic diameter (LVEDD) was a consistent both in HFrEF (P=0.031) and HFpEF (P=0.003). During a median follow-up time of 33.39 months, 69 patients (13.8%) met the primary endpoint. The survival of PH patients was significantly worse than that of patients without PH (P=0.001). Diastolic pressure gradient (DPG) was a significant prognostic variable both in HFrEF (HR=1.057, 95% CI=1.007-1.108, P=0.024) and HFpEF (HR=1.094, 95% CI=1.009-1.187, P=0.030). Patients with a DPG ≥ 7 mmHg had a worse survival compared to those whose DPG < 7 mmHg both in HFrEF (log rank test, P=0.047) and in HFpEF (P=0.016). Conclusion Though the prevalence, characteristics and prognosis of PH differ between HFrEF and HFpEF, PH-LHD is a common complication and has an adverse effect on the prognosis.

Background: Cardiopulmonary exercise test (CPET) is a crucial tool for the functional evaluation of cardiac patients. We hypothesized that VO2 max and VE/VCO2 slope are not the only parameters of CPET able to predict major cardiac events (mortality or cardiac transplantation urgently or elective). Objectives: We aimed to identify the best CPET predictors of major cardiac events in patients with severe chronic heart failure and to propose an integrated score that could be applied for their prognostic evaluation. Methods: We evaluated 140 patients with chronic heart failure who underwent CPET between 2011 and 2019. Major cardiac events were evaluated during follow-up. Univariate and multivariate logistic regression analysis were applied to study the predictive value of different clinical, echocardiographic and CPET parameters in relation to the major cardiac events. A score was generated and c-statistic was used for the comparisons. Results: Thirty-nine patients (27.9%) died or underwent cardiac transplantation over a median follow-up of 48 months. Five parameters (maximal workload, breathing reserve, left ventricular ejection fraction, diastolic dysfunction and non-idiopathic cardiomyopathy) were used to generate a risk score that had better risk discrimination than NYHA dyspnea scale, VO2 max, VE/VCO2 slope > 35 alone, and combined VO2 max and VE/VCO2 slope (p= 0.009, 0.004, < 0.001 and 0.005 respectively) in predicting major cardiac events. Conclusions: A composite score of CPET and clinical/echocardiographic data is more reliable than the single use of VO2max or combined with VE/VCO2 slope to predict major cardiac events.

The Impact

Introduction: The proposed revision of hemodynamic definition of pulmonary hypertension (PH) adopts a lower threshold of mean pulmonary artery pressure (mPAP) > 20 mmHg. In addition, pulmonary vascular resistance (PVR) ≥ 3 Wood units (WU) is included as the definition of pre-capillary component of PH. Heart failure (HF) with preserved ejection fraction (HFpEF) can develop pre-capillary PH as well as post-capillary PH. We aimed to investigate the impact of the proposed definition of PH on clinical diagnosis of PH associated with HFpEF. Methods: From the PURSUIT-HFpEF (Prospective Multicenter Observational Study of Patients with Heart Failure with Preserved Ejection Fraction) registry, 225 patients who were hospitalized with HF and underwent right heart catheterization were categorized according to the current guidelines and the proposed definition of PH: non-PH, isolated post-capillary PH (Ipc-PH), pre-capillary PH, and combined pre- and post-capillary PH (Cpc-PH). In the proposed definition, patients with mPAP > 20 mmHg, PVR < 3 WU, and pulmonary artery wedge pressure ≤ 15 mmHg do not meet criteria for any of the above categories and are categorized as “unclassified PH”. Results: Prevalence of PH was significantly increased in the proposed definition compared to that in the current definition (51% vs 29%, p<0.0001), with a doubled frequency of pre-capillary PH (Fig A). Furthermore, 24 patients (11%) were diagnosed as unclassified PH and accounted for 22% of those with PH by the proposed definition. Among the PH categories in the proposed definition, Cpc-PH category was significantly relevant for worse prognosis at 1 year after discharge in patients with HFpEF (p=0.03 vs non-PH by log-rank test with Bonferroni's correction) (Fig 2). Conclusions: The new definition of PH resulted in a remarkable increase of prevalence of PH in HFpEF with a quite a few patients with unclassified PH and doubled frequency of pre-capillary PH.

Pulmonary Arterial

The diagnosis of pulmonary hypertension (PH) relies on the haemodynamic criterion of mean pulmonary arterial pressure greater than or equal to 25 mmHg, assessed by right heart catheterization. The scope of this chapter is to discuss the key elements of clinical assessment of PH patients and the decision process to indicate right heart catheterization. Investigation must get through all the possible causes of PH according to their probability and frequency in the population. Echocardiography is the most important non-invasive test as an indicator for further diagnostic evaluation. Patients who are eligible for right heart catheterization should always be referred to PH centres, where technical skills and standardized procedures will enable maximal reliability of haemodynamic measurement. In the reference centre, a multidisciplinary team will discuss clinical and haemodynamic data, to propose the best therapeutic and follow-up schedule.

ObjectiveTo characterise the association between socioeconomic deprivation and adverse outcomes in patients with chronic heart failure (CHF).MethodsWe prospectively observed 1802 patients with CHF and left ventricular ejection fraction (LVEF) ≤45%, recruited in four UK hospitals between 2006 and 2014. We assessed the association between deprivation defined by the UK Index of Multiple Deprivation (IMD) and: mode-specific mortality (mean follow-up 4 years); mode-specific hospitalisation; and the cumulative duration of hospitalisation (after 1 year).ResultsA 45-point difference in mean IMD score was noted between patients residing in the least and most deprived quintiles of geographical regions. Deprivation was associated with age, sex and comorbidity, but not CHF symptoms, LVEF or prescribed drug therapy. IMD score was associated with the risk of age-sex adjusted all-cause mortality (6% higher risk per 10-unit increase in IMD score; 95% CI 2% to 10%; P=0.004), and non-cardiovascular mortality (9% higher risk per 10-unit increase in IMD score; 95% CI 3% to 16%; P=0.003), but not cardiovascular mortality. All-cause, but not heart failure-specific, hospitalisation was also more common in the most deprived patients. Overall, patients spent a cumulative 3.3 days in hospital during 1 year of follow-up, with IMD score being associated with the age-sex adjusted cumulative duration of hospitalisations (4% increase in duration per 10-unit increase in IMD score; 95% CI 3% to 6%; P<0.0005).ConclusionsSocioeconomic deprivation in people with CHF is linked to increased risk of death and hospitalisation due to an excess of non-cardiovascular events.

Background. Cardiogenic shock (CS) remains a major challenge in contemporary cardiology. Data regarding CS etiologies and their prognosis are limited and mainly derived from tertiary referral centers. Aims. To investigate the current etiologies of cardiogenic shock and their associated short- and long-term outcomes in a secondary center without surgical back-up. Methods. We performed an observational prospective monocenter study. All patients admitted for a first episode of CS related to left ventricular dysfunction were enrolled. The definition of CS was consistent with the European Society of Cardiology guidelines. Patients were followed for 6 months. Etiologies were analyzed, and survival rates derived from Kaplan-Meier estimates were compared with the log-rank test. Results. Between January 2015 and January 2016, 152 patients were included. The first most common cause of CS was acute decompensation of chronic heart failure (CHF). Acute coronary syndromes (ACS) were the second most common cause of CS (35.4%). At one month, the all-cause mortality rate was 39.5% and was similar between ACS and CHF (43% vs 35%, respectively; p=0.7). In a landmark analysis between 1 and 6 months, we observed a significantly higher mortality in patients with CHF than in patients with ACS (18% vs. 0%; p=0.01). Conclusions. In the present registry, acute decompensation of chronic heart failure was the most common cause of CS, while ACS complicated by CS was the second most common cause. Of importance, acute decompensation of CHF was associated with a significantly worse outcome than ACS in the long term.

Abstract Aims Pulmonary hypertension (PH) carries a poor prognosis in patients with non-ischaemic dilated cardiomyopathy (NIDC). Cardiac magnetic resonance (CMR) with late gadolinium enhancement (LGE) evaluation can identify myocardial abnormalities. In particular, junctional LGE is already an established marker of adverse right ventricular (RV) remodelling in patients with pre-capillary PH. This study sought to assess the prevalence of junctional LGE by CMR in NIDC, its relationship with hemodynamic parameters and, moreover, its prognostic significance. Methods and results Patients with NIDC who underwent right heart catheterization (RHC) and CMR within 3 months in a tertiary hospital were enrolled. Patients with acute heart failure were excluded. Among others, RV and left ventricular (LV) volumes, junctional LGE at CMR, pulmonary artery pressure (PAP) and pulmonary capillary wedge pressure (PCWP) at RHC were tabulated. Pulmonary hypertension was defined accordingly to current Guidelines (median PAP at RHC ≥ 25 mmHg). The primary endpoint consisted of heart failure (HF) hospitalization during follow-up. A total of 188 patients [median age 49 (SD 15), 71% males] were evaluated. At morpho-functional CMR evaluation, most subjects (76%) had important systolic dysfunction (LV EF ≤ 35%). Junctional LGE was observed in 83 (44%) patients. Among patients with junctional LGE, 21 had LGE confined only to the junctional region, while 61 had also mid-wall interventricular septal stria and 21 a mid-wall stria in the lateral free LV wall. Patients with junctional LGE had lower RV EF (49% vs. 56%, P &lt; 0.001) and LV EF (27% vs. 30%, P = 0.012) when compared to those without junctional LGE although no differences in LV and RV dimensions were found. RHC showed PH in 83 patients (44%). Patients with junctional LGE showed a worse hemodynamic profile in terms of PH (55% vs. 36%; P = 0.011) and increase in PCWP (PCWP &gt; 15 mmHg in 60% vs. 42%; P = 0.015) compared to subjects without junctional LGE. Among 79 patients with PH and PCWP &gt; 15 mmHg, 75 (95%) had a combined post capillary and pre-capillary PH (diastolic pressure gradient ≥7 mmHg). Univariate analysis showed that junctional LGE was associated with a worse hemodynamic profile; on multivariable model, RV EF was significantly associated with the presence of junctional LGE (OR: 0.91; 95% CI: 0.87–0.96, P &lt; 0.001). During a median follow-up of 58 months, 33 patients (18%) died or underwent heart transplantation/ventricular assist device implantation, 17% in the junctional LGE group vs. 18% among those without junctional LGE. Thirty-eight patients (20%) had at least one episode of HF, 22 among junctional LGE group and 16 in control group (27% vs. 15%, P = 0.056). When adjusted for age, junctional LGE resulted a significant determinant of HF hospitalization (OR: 2.13, 95% CI: 1.02–4.44, P = 0.044). Conclusions Junctional LGE is detectable in almost half of NIDC patients and it is related to a worse haemodynamic profile, characterized by PH and elevated PCWP. Moreover, after adjustment for age, it was a significant determinant of HF hospitalization during follow-up in our population. Junctional LGE can therefore represent a useful prognostic tool, as marker of adverse ventricular remodelling likely related to ventricular interdependence.

Sarcoidosis-associated pulmonary hypertension (SAPH) has been reported in 10% of all sarcoidosis patients. In the United States, the prevalence is similar to that reported for scleroderma. There are several possible mechanisms for SAPH, including vascular compression, granulomatous angiitis, left ventricular (LV) dysfunction, and fibrosis of lung tissue. The prognosis of those with LV dysfunction is significantly better than those with precapillary pulmonary hypertension. Screening for SAPH includes evaluation of dyspnea by 6-minute walk test, echocardiography, and measurement of pulmonary artery diameter on computer tomographic scan. Right heart catheterization remains the definitive test for characterizing SAPH. Treatment for precapillary hypertension has been shown to improve pulmonary hemodynamics. However, it is still unclear whether such treatments will change the natural course of the disease, especially in those with severe fibrosis.
