Clinical predictors of right ventricular dysfunction and association with adverse outcomes in peripartum cardiomyopathy. ESC Heart Fail 2024; 11:422-432. [PMID: 38030384 PMCID: PMC10804155 DOI: 10.1002/ehf2.14583] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2023] [Revised: 10/05/2023] [Accepted: 10/31/2023] [Indexed: 12/01/2023] Open
Abstract
AIMS We sought to identify factors associated with right ventricular (RV) dysfunction and elevated pulmonary artery systolic pressure (PASP) and association with adverse outcomes in peripartum cardiomyopathy (PPCM). METHODS AND RESULTS We conducted a multi-centre cohort study to identify subjects with PPCM with the following criteria: left ventricular ejection fraction (LVEF) < 40%, development of heart failure within the last month of pregnancy or 5 months of delivery, and no other identifiable cause of heart failure with reduced ejection fraction. Outcomes included a composite of (i) major adverse events (need for extracorporeal membrane oxygenation, ventricular assist device, orthotopic heart transplantation, or death) or (ii) recurrent heart failure hospitalization. RV function was obtained from echocardiogram reports. In total, 229 women (1993-2017) met criteria for PPCM. Mean age was 32.4 ± 6.8 years, 28% were of African descent, 50 (22%) had RV dysfunction, and 38 (17%) had PASP ≥ 30 mmHg. After a median follow-up of 3.4 years (interquartile range 1.0-8.8), 58 (25%) experienced the composite outcome of adverse events. African descent, family history of cardiomyopathy, LVEF, and PASP were significant predictors of RV dysfunction. Using Cox proportional hazards models, we found that women with RV dysfunction were three times more likely to experience the adverse composite outcome: hazard ratio 3.21 (95% confidence interval: 1.11-9.28), P = 0.03, in a multivariable model adjusting for age, race, body mass index, preeclampsia, hypertension, diabetes, kidney disease, and LVEF. Women with PASP ≥ 30 mmHg had a lower probability of survival free from adverse events (log-rank P = 0.04). CONCLUSIONS African descent and family history of cardiomyopathy were significant predictors of RV dysfunction. RV dysfunction and elevated PASP were significantly associated with a composite of major adverse cardiac events. This at-risk group may prompt closer monitoring or early referral for advanced therapies.

Abstract
Peripartum cardiomyopathy is the development of heart failure toward the end of pregnancy or in the months after delivery in the absence of other attributable causes, with left ventricular systolic dysfunction and a left ventricular ejection fraction (LVEF) generally <45%. Given that patients are relatively young at the time of diagnosis, this study was performed to summarize current evidence surrounding the long-term cardiac outcomes. MEDLINE, Embase, Cochrane CENTRAL, and CINAHL were searched for original studies that reported long-term (>1 year) patient outcomes. Of the 3,144 total records identified, 62 studies involving 4,282 patients met the selection criteria. The mean LVEF was 28% at diagnosis and 47% at the time of the last follow-up. Approximately half of the patients achieved myocardial recovery (47%), most commonly defined as an LVEF >50% (n = 21). The prevalence of implantable cardioverter-defibrillator use, left ventricular assist device implantation, and heart transplantation was 12%, 7%, and 11%, respectively. The overall all-cause mortality was 9%, and despite having more cardiovascular risk factors, patients residing in high-income countries had superior outcomes, including reduced rates of mortality.

Abstract
Cardiovascular diseases (CVD) remain the leading cause of mortality worldwide. Although major diagnostic and therapeutic advances have significantly improved the prognosis of patients with CVD in the past decades, these advances have less benefited women than age-matched men. Noninvasive cardiac imaging plays a key role in the diagnosis of CVD. Despite shared imaging features and strategies between both sexes, there are critical sex disparities that warrant careful consideration, related to the selection of the most suited imaging techniques, to technical limitations, and to specific diseases that are overrepresented in the female population. Taking these sex disparities into consideration holds promise to improve management and alleviate the burden of CVD in women. In this review, we summarize the specific features of cardiac imaging in four of the most common presentations of CVD in the female population including coronary artery disease, heart failure, pregnancy complications, and heart disease in oncology, thereby highlighting contemporary strengths and limitations. We further propose diagnostic algorithms tailored to women that might help in selecting the most appropriate imaging modality.

Abstract
INTRODUCTION Peripartum cardiomyopathy (PPCM) is an important cause of maternal mortality and morbidity. But, there is a paucity of prospective data on outcomes and prognostic markers in patients receiving contemporary evidence-based therapy, particularly in developing countries. METHODS This was a single centre, prospective, cohort study on 43 PPCM patients who were followed for 6 months. The primary endpoint was a composite incidence of decompensation related re-hospitalization, all-cause death, and poor recovery (defined as left ventricular ejection fraction, LVEF: <45% at 6 months). Multivariate logistic regression analysis was performed to identify the independent predictors and Kaplan-Meier plots for event (re-hospitalization or death) free survival were computed at their optimal cut-offs. RESULTS Mean LVEF at presentation was 34.7%. Two patients died during index hospitalization but there were no deaths during follow-up and 63.4% of patients had full LV recovery after discharge. 32.5% of the study population experienced the composite endpoint with high left atrial volume index (LAVi), and low right ventricular fractional area change (RVFAC) at presentation as independent predictors. Use of Inotropic therapy during index hospitalization (with dobutamine or levosimendan) and bromocriptine therapy were not associated with better outcome. CONCLUSIONS At the end of 6 months after PPCM diagnosis, about 61% of patients had full LV functional recovery with a mortality rate of 4.7%. RVFAC (<31.4% with 86% accuracy) and LAVi (>29.6 ml/m2 with 72% accuracy) at presentation but not LVEF, predicts poor outcomes. Presence of both these risk factors at index hospitalization was associated with a significantly lower event free survival compared to patients without these predictors.

Abstract
The burden of pregnancy-related heart disease has dramatically increased over the last decades due to the increasing age at first pregnancy and higher prevalence of cardiovascular risk factors such as diabetes, hypertension, and obesity. Pregnancy is associated with physiological changes in the cardiovascular system, including hemodynamic, metabolic, and hormonal adaptations to meet the increased metabolic demands of the mother and fetus. It has been postulated that pregnancy may act as a cardiovascular stress test to identify women at high risk for heart disease, where the inability to adequately adapt to the physiologic stress of pregnancy may reveal the presence of genetic susceptibility to cardiovascular disease or accelerate the phenotypic expression of both inherited and acquired heart diseases, such as peripartum cardiomyopathy (PPCM). PPCM is a rare and incompletely understood clinical condition. Despite recent advances in the understanding of its pathogenesis, PPCM is not attributable to a well-defined pathological mechanism, and therefore, its diagnosis still relies on the exclusion of overlapping dilated phenotypes. Cardiac imaging plays a key role in any peripartum woman with signs and symptoms of heart failure in establishing the diagnosis, ruling out life-threatening complications, guiding therapy and conveying prognostic information. Echocardiography represents the first-line imaging technique, given its robust diagnostic yield and its favorable cost-effectiveness. Cardiovascular magnetic resonance is a biologically safe high-throughput modality that allows accurate morpho-functional assessment of the cardiovascular system in addition to the unique asset of myocardial tissue characterization as a pivotal piece of information in the pathophysiological puzzle of PPCM. In this review, we will highlight current evidence on the role of multimodality imaging in the differential diagnosis, prognostic assessment, and understanding of the pathophysiological basis of PPCM.

Abstract
Right ventricular dysfunction is highly prevalent across cardiopulmonary diseases and independently predicts death in both heart failure (HF) and pulmonary hypertension (PH). Progression towards right ventricular failure (RVF) can occur in spite of optimal medical treatment of HF or PH, highlighting current insufficient understanding of RVF molecular pathophysiology. To identify molecular mechanisms that may distinctly underlie RVF, we investigated the cardiac ventricular transcriptome of advanced HF patients, with and without RVF. Using an integrated systems genomic and functional biology approach, we identified an RVF-specific gene module, for which WIPI1 served as a hub and HSPB6 and MAP4 as drivers, and confirmed the ventricular specificity of Wipi1, Hspb6, and Map4 transcriptional changes in adult murine models of pressure overload induced RV- versus LV- failure. We uncovered a shift towards non-canonical autophagy in the failing RV that correlated with RV-specific Wipi1 upregulation. In vitro siRNA silencing of Wipi1 in neonatal rat ventricular myocytes limited non-canonical autophagy and blunted aldosterone-induced mitochondrial superoxide levels. Our findings suggest that Wipi1 regulates mitochondrial oxidative signaling and non-canonical autophagy in cardiac myocytes. Together with our human transcriptomic analysis and corroborating studies in an RVF mouse model, these data render Wipi1 a potential target for RV-directed HF therapy.
