Abstract
Purpose We investigated the risk factors and characteristic clinical features of peripartum cardiomyopathy (PPCM) to lay the groundwork for early identification, screening, diagnosis, and intervention in high-risk pregnant women. Patients and methods A retrospective case-control study was conducted to analyze data from 44 patients with PPCM and 226 normal pregnant women from a Chinese population. Results Significant differences were found between the groups in terms of various factors such as age, body mass index (BMI), heart rate, and medical history. Logistic regression models identified abnormal electrocardiography (OR=18.852), upper respiratory tract infection (OR=41.822), gestational hypertension (OR=18.188), and cesarean section (OR=8.394) as risk factors for PPCM. Common clinical features observed in patients with PPCM included cough, wheezing, and chest tightness (68.18%), left heart enlargement (56.82%) and valvular insufficiency (81.82%). Additionally, cardiotropic virus was detected in a subset of patients (43.18%) and NT-proBNP was elevated ≥ 400 pg/mL (81.82%). Conclusion In the Chinese population, the presence of abnormal electrocardiograms during pregnancy, history of upper respiratory tract infection, gestational hypertension, and maternal choice of cesarean section suggest the possibility of PPCM development. Factors such as advanced age, family history of cardiovascular disease, gestational diabetes mellitus, eclampsia, anemia, and hypoproteinemia should be considered. Clinically, patients present with cough, wheezing, chest tightness, enlarged left heart, valvular insufficiency and NT-proBNP elevated ≥ 400 pg/mL. This study could serve as a valuable reference for medical practitioners for the early identification and screening of patients with PPCM.

[PMID: 38996860 DOI: 10.1016/j.ahj.2024.07.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/02/2024] [Revised: 07/02/2024] [Accepted: 07/03/2024] [Indexed: 07/14/2024]
Abstract
BACKGROUND Black women with peripartum cardiomyopathy (PPCM) have a higher prevalence of hypertensive disorders of pregnancy (HDP) and worse clinical outcomes compared with non-Black women. We examined the impact of HDP on myocardial recovery in Black women with PPCM. METHODS A total of 100 women were enrolled into the Investigation in Pregnancy Associated Cardiomyopathy (IPAC) study. Left ventricular ejection fraction (LVEF) was assessed by echocardiography at entry, 6, and 12-months post-partum (PP). Women were followed for 12 months postpartum and outcomes including persistent cardiomyopathy (LVEF ≤35%), left ventricular assist device, (LVAD), cardiac transplantation, or death were examined in subsets based on race and the presence of HDP. RESULTS Black women with HDP were more likely to present earlier compared to Black women without HDP (days PP HDP: 34 ± 21 vs 54 ± 27 days, P = .03). There was no difference in LVEF at study entry for Black women based on HDP, but better recovery with HDP at 6 (HDP: 52 ± 11% vs no HDP: 40 ± 14%, P = .03) and 12-months (HDP:53 ± 10% vs no HDP:40 ± 16%, P = .02). At 12-months, Black women overall had a lower LVEF than non-Black women (P < .001), driven by less recovery in Black women without HDP compared to non-Black women (P < .001). In contrast, Black women with HDP had a similar LVEF at 12 months compared to non-Black women (P = .56). CONCLUSIONS In women with PPCM, poorer outcomes evident in Black women were driven by women without a history of HDP. In Black women, a history of HDP was associated with earlier presentation and recovery which was comparable to non-Black women.

Abstract
BACKGROUND AND AIMS The epidemiology of peripartum cardiomyopathy (PPCM) in Europe is poorly understood and data on long-term outcomes are lacking. A retrospective, observational, population-level study of validated cases of PPCM in Scotland from 1998 to 2017 was conducted. METHODS Women hospitalized with presumed de novo left ventricular systolic dysfunction around the time of pregnancy and no clear alternative cause were included. Each case was matched to 10 controls. Incidence and risk factors were identified. Morbidity and mortality were examined in mothers and children. RESULTS The incidence of PPCM was 1 in 4950 deliveries. Among 225 women with PPCM, obesity, gestational hypertensive disorders, and multi-gestation were found to be associated with having the condition. Over a median of 8.3 years (9.7 years for echocardiographic outcomes), 8% of women with PPCM died and 75% were rehospitalized for any cause at least once. Mortality and rehospitalization rates in women with PPCM were ∼12- and ∼3-times that of controls, respectively. The composite of all-cause death, mechanical circulatory support, or cardiac transplantation occurred in 14%. LV recovery occurred in 76% and, of those who recovered, 13% went on to have a decline in LV systolic function despite initial recovery. The mortality rate for children born to women with PPCM was ∼5-times that of children born to controls and they had an ∼3-times greater incidence of cardiovascular disease over a median of 8.8 years. CONCLUSIONS PPCM affected 1 in 4950 women around the time of pregnancy. The condition is associated with considerable morbidity and mortality for the mother and child. There should be a low threshold for investigating at-risk women. Long term follow-up, despite apparent recovery, should be considered.

Abstract
PURPOSE OF REVIEW This review aims to explore the applications of digital technology in cardiovascular care across African countries. It highlights the opportunities and challenges associated with leveraging technology to enhance patient self-monitoring, remote patient-clinician interactions, telemedicine, clinician and patient education, and research facilitation. The purpose is to highlight how technology can transform cardiovascular care in Africa. RECENT FINDINGS Recent findings indicate that the increasing penetration of mobile phones and internet connectivity in Africa offers a unique opportunity to improve cardiovascular care. Smartphone-based applications and text messaging services have been employed to promote self-monitoring and lifestyle management, although challenges related to smartphone ownership and digital literacy persist. Remote monitoring of patients by clinicians using home-based devices and wearables shows promise but requires greater accessibility and validation studies in African populations. Telemedicine diagnosis and management of cardiovascular conditions demonstrates significant potential but faces adoption challenges. Investing in targeted clinician and patient education on novel digital technology and devices as well as promoting technology-assisted research for participant recruitment and data collection can facilitate cardiovascular care advancements in Africa. Technology has the potential to revolutionize cardiovascular care in Africa by improving access, efficiency, and patient outcomes. However, barriers related to limited resources, supportive infrastructure, digital literacy, and access to devices must be addressed. Strategic actions, including investment in digital infrastructure, training programs, community collaboration, and policy advocacy, are crucial to ensuring equitable integration of digital health solutions.

Abstract
BACKGROUND Peripartum cardiomyopathy (PPCM) is a rare cause of heart failure occurring during pregnancy. Its prevalence seems more frequent in Africa but its epidemiological, clinical and evolutionary particularities remain unknown. This study aimed to evaluate the epidemiological features and mortality risk factors of PPCM. MATERIAL AND METHOD We conducted a retrospective cross-sectional study over 38 months (January 2018 to March 2021) in 3 hospitals in the city of Douala(Cameroon). We included all patients with heart failure between the last month of pregnancy and 5 months after delivery without an identified cause. Were excluded, files not containing data on echocardiography, patients with heart failure without dilation or with LVEF≥ 45% and patients with a history of heart disease of known aetiology. Chi² tests and binary logistic regression were used for data analysis; the survival curve according to Kaplan Meier was drawn for the evolution. The threshold of significance was set at 0.05. RESULTS A total of 2102 medical records of women with heart failure were searched. In these records, a total of 59 patients showed signs of peripartum heart failure and only 29 fulfilled the inclusion criteria. From a socio-demographic point of view, the average age was 29 ± 7 years and 51.7% of patients were over 30 years old. Among these patients, 79.3% of patients lived in urban areas and 10.3% of patients had a low socio-economic level. The hospital frequency of PPCM was 1.3%. Clinically, primiparous and pauciparous women were the most affected; the diagnosis was made after more than a month of progression in 65.5% of patients. Dyspnea was present in all patients. In addition, 89.7% of patients had a left ventricular end-diastolic diameter ≥ 62 m, 48.3 % had a left ventricular ejection fraction (LVEF) between 30% and 45%, and 51.7% had an LVEF < 30%. The associated mortality rate was 27.7%. The only prognostic factor independently associated with mortality was age < 30 years. CONCLUSION The frequency of PPCM is relatively low in Cameroonian urban settings. Moreover, its diagnosis is generally delayed and it induces high mortality. Its occurrence in a woman under the age of 30 is a factor of poor prognosis.

High prevalence of reduced fertility and use of assisted reproductive technology in a German cohort of patients with peripartum cardiomyopathy. Clin Res Cardiol 2023; 112:343-352. [PMID: 35562615 PMCID: PMC9998571 DOI: 10.1007/s00392-022-02034-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/26/2022] [Accepted: 05/02/2022] [Indexed: 11/03/2022]
Abstract
BACKGROUND Over the past decades the use of assisted reproduction technology (ART) increased worldwide. ARTs are associated with an elevated risk for cardiovascular complications. However, a potential relation between subfertility/ARTs and the heart disease peripartum cardiomyopathy (PPCM) has not been systematically analyzed yet. METHODS A retrospective cohort study was carried out, including n = 111 PPCM patients from the German PPCM registry. Data from PPCM patients were compared to those from postpartum women in the German general population. RESULTS The prevalence of reported subfertility was high among PPCM patients (30%; 33/111). Most of the subfertile PPCM patients (55%; 18/33) obtained vitro fertilizations (IVF) or intracytoplasmic sperm injections (ICSI). PPCM patients were older (p < 0.0001), the percentage of born infants conceived by IVF/ICSI was higher (p < 0.0001) with a higher multiple birth (p < 0.0001), C-section (p < 0.0001) and preeclampsia rate (p < 0.0001), compared to postpartum women. The cardiac outcome was comparable between subfertile and fertile PPCM patients. Whole exome sequencing in a subset of n = 15 subfertile PPCM patients revealed that 33% (5/15) carried pathogenic or likely pathogenic gene variants associated with cardiomyopathies and/or cancer predisposition syndrome. CONCLUSIONS Subfertility occurred frequently among PPCM patients and was associated with increased age, hormonal disorders, higher twin pregnancy rate and high prevalence of pathogenic gene variants suggesting a causal relationship between subfertility and PPCM. Although this study found no evidence that the ART treatment per se increases the risk for PPCM or the risk for an adverse outcome, women with subfertility should be closely monitored for signs of peripartum heart failure.

Abstract
In 2015, the United Nations set important targets to reduce premature cardiovascular disease (CVD) deaths by 33% by 2030. Africa disproportionately bears the brunt of CVD burden and has one of the highest risks of dying from non-communicable diseases (NCDs) worldwide. There is currently an epidemiological transition on the continent, where NCDs is projected to outpace communicable diseases within the current decade. Unchecked increases in CVD risk factors have contributed to the growing burden of three major CVDs-hypertension, cardiomyopathies, and atherosclerotic diseases- leading to devastating rates of stroke and heart failure. The highest age standardized disability-adjusted life years (DALYs) due to hypertensive heart disease (HHD) were recorded in Africa. The contributory causes of heart failure are changing-whilst HHD and cardiomyopathies still dominate, ischemic heart disease is rapidly becoming a significant contributor, whilst rheumatic heart disease (RHD) has shown a gradual decline. In a continent where health systems are traditionally geared toward addressing communicable diseases, several gaps exist to adequately meet the growing demand imposed by CVDs. Among these, high-quality research to inform interventions, underfunded health systems with high out-of-pocket costs, limited accessibility and affordability of essential medicines, CVD preventive services, and skill shortages. Overall, the African continent progress toward a third reduction in premature mortality come 2030 is lagging behind. More can be done in the arena of effective policy implementation for risk factor reduction and CVD prevention, increasing health financing and focusing on strengthening primary health care services for prevention and treatment of CVDs, whilst ensuring availability and affordability of quality medicines. Further, investing in systematic country data collection and research outputs will improve the accuracy of the burden of disease data and inform policy adoption on interventions. This review summarizes the current CVD burden, important gaps in cardiovascular medicine in Africa, and further highlights priority areas where efforts could be intensified in the next decade with potential to improve the current rate of progress toward achieving a 33% reduction in CVD mortality.

Abstract
The outcome of this review is to assess the association between pre-pregnancy obesity and PPCM incidence. There were a total of 5.373.581 participants were included in this study. Pre-pregnancy obesity was significantly associated with PPCM incidence compared to normal-weight subjects (OR = 1.79 (1.16,2.76); p = 0.008; I2 = 59%, Pheterogeneity = 0.04). The sub-group analysis showed that pre-pregnancy women with obesity class I (OR = 1.58 (1.20,2.07); p = 0.001; I2 = 0%, Pheterogeneity = 0.64) and class II and III (OR = 2.65 (2.04,3.45); p < 0.001; I2 = 6%, Pheterogeneity = 0.36) was significantly associated with PPCM incidence compared to normal-weight subjects.

Abstract
Peripartum cardiomyopathy (PPCM) is a potentially fatal form of idiopathic heart failure with variable prevalence across different countries and ethnic groups. The cause of PPCM is unclear, but environmental and genetic factors and pregnancy-associated conditions such as pre-eclampsia can contribute to the development of PPCM. Furthermore, animal studies have shown that impaired vascular and metabolic function might be central to the development of PPCM. A better understanding of the pathogenic mechanisms involved in the development of PPCM is necessary to establish new therapies that can improve the outcomes of patients with PPCM. Pregnancy hormones tightly regulate a plethora of maternal adaptive responses, including haemodynamic, structural and metabolic changes in the cardiovascular system. In patients with PPCM, the peripartum period is associated with profound and rapid hormonal fluctuations that result in a brief period of disrupted cardiovascular (metabolic) homeostasis prone to secondary perturbations. In this Review, we discuss the latest studies on the potential pathophysiological mechanisms of and risk factors for PPCM, with a focus on maternal cardiovascular changes associated with pregnancy. We provide an updated framework to further our understanding of PPCM pathogenesis, which might lead to an improvement in disease definition.

Abstract
Background: A wide knowledge gap exists on the clinical profiles and outcomes of heart failure (HF) in sub-Saharan Africa. Objectives: To determine the clinical profiles and outcomes of HF patients from five African countries. Methods: The INTERnational Congestive Heart Failure Study (INTER-CHF) is a prospective, multicenter cohort study. A total of 1,294 HF patients were consecutively recruited from Nigeria (383 patients), South Africa (169 patients), Sudan (501 patients), Uganda (151patients), and Mozambique (90 patients). HF was defined according to the Boston criteria for diagnosis. Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA) score. Results: Of the 1294 patients, 51.4% were recruited as out-patients, 53.7% had HF with reduced ejection fraction (EF), 30.1% had HF with mid-range EF and 16.2% had HF with preserved EF (16.2%). The commonest etiologies of HF were hypertensive heart disease (35%) and ischemic heart disease (20%). The mean MoCA score was highest in Uganda (24.3 ± 1.1) and lowest in Sudan (13.6 ± 0.3). Prescriptions for guideline-recommended HF therapies were poor; only 1.2% of South African patients received an Implantable Cardioverter Defibrillator, and none of the patients received Cardiac Resynchronised Therapy. The composite outcome of death or HF hospitalization at one year among the patients was highest in Sudan (59.7%) and lowest in Mozambique (21.1%). Six variables were associated with higher mortality risk, while digoxin use (adjusted hazard ratio [aHR]: 0.69; 95% confidence interval [CI]: 0.49–0.97; p = 0.034) and 10mmHg unit increase in systolic blood pressure (aHR 0.86; 95%CI 0.81–0.93; p < 0.001) were associated with lower risk for mortality. Conclusions: This is the largest HF study in Africa that included in- and out-patients from the West, East, North, Central and South African sub-regions. Clinically relevant differences, including cognitive functional impairment, were found between the involved countries.

Abstract
Aims The prospective, multicentre Peripartum Cardiomyopathy in Nigeria (PEACE) registry originally demonstrated a high prevalence of peripartum cardiomyopathy (PPCM) among patients originating from Kano, North‐West Nigeria. In a post hoc analysis, we sought to determine if this phenomenon was characterized by a differential case profile and outcome among PPCM cases originating elsewhere. Methods and results Overall, 199 (81.6%) of a total 244 PPCM patients were recruited from three sites in Kano, compared with 45 patients (18.4%) from 11 widely dispersed centres across Nigeria. Presence and extent of ventricular myocardial remodelling during follow‐up, relative to baseline status, were assessed by echocardiography. During median 17 months follow‐up, Kano patients demonstrated significantly better myocardial reverse remodelling than patients from other sites. Overall, 50.6% of patients from Kano versus 28.6% from other regions were asymptomatic (P = 0.029) at study completion, with an accompanying difference in all‐cause mortality (17.6% vs. 22.2% respectively, P = 0.523) not reaching statistical significance. Alternatively, 135/191 (84.9%) of Kano patients had selenium deficiency (<70 μg/L), and 46/135 (34.1%) of them received oral selenium supplementation. Critically, those that received selenium supplementation demonstrated better survival (6.5% vs. 21.2%; P = 0.025), but the supplement did not have significant impact on myocardial remodelling. Conclusions This study has shown important non‐racial regional disparities in the clinical features and outcomes of PPCM patients in Nigeria, that might partly be explained by selenium supplementation.

Abstract
Peripartum cardiomyopathy (PPCM) is a potentially life-threatening condition in which heart failure and systolic dysfunction occur late in pregnancy or within months following delivery. To date, no reliable biomarkers or therapeutic interventions for the condition exist, thus necessitating an urgent need for identification of novel PPCM drug targets and candidate biomarkers. Leads for novel treatments and biomarkers are therefore being investigated worldwide. Pregnancy is generally accompanied by dramatic hemodynamic changes, including a reduced afterload and a 50% increase in cardiac output. These increased cardiac stresses during pregnancy potentially impair protein folding processes within the cardiac tissue. The accumulation of misfolded proteins results in increased toxicity and cardiac insults that trigger heart failure. Under stress conditions, molecular chaperones such as heat shock proteins (Hsps) play crucial roles in maintaining cellular proteostasis. Here, we critically assess the potential role of Hsps in PPCM. We further predict specific associations between the Hsp types Hsp70, Hsp90 and small Hsps with several proteins implicated in PPCM pathophysiology. Furthermore, we explore the possibility of select Hsps as novel candidate PPCM biomarkers and drug targets. A better understanding of how these Hsps modulate PPCM pathogenesis holds promise in improving treatment, prognosis and management of the condition, and possibly other forms of acute heart failure.

Abstract
BACKGROUND Nigeria has the highest incidence of peripartum cardiomyopathy (PPCM) in the world. However, data on PPCM-related outcomes are limited. OBJECTIVES The purpose of this study was to examine the clinical profile, myocardial remodeling, and survival of patients with PPCM in Nigeria. METHODS This study consecutively recruited 244 PPCM patients (median 7 months postpartum) at 14 sites in Nigeria and applied structured follow-up for a median of 17 months (interquartile range: 14 to 20 months). Left ventricular reverse remodeling (LVRR) was defined as the composite of left ventricular (LV) end-diastolic dimension <33 mm/m2 and absolute increase in left ventricular ejection fraction (LVEF) ≥10%. LV full recovery was defined as LVEF ≥55%. RESULTS Overall, 45 (18.7%) patients died during follow-up. Maternal age <20 years (hazard ratio [HR]: 2.40; 95% confidence interval (CI): 1.27 to 4.54), hypotension (HR: 1.87; 95% CI: 1.02 to 3.43), tachycardia (HR: 2.38; 95% CI: 1.05 to 5.43), and LVEF <25% at baseline (HR: 2.11; 95% CI: 1.12 to 3.95) independently predicted mortality. Obesity (HR: 0.16; 95% CI: 0.04 to 0.55) and regular use of beta-blockers at 6-month follow-up (HR: 0.20; 95% CI: 0.09 to 0.41) were independently associated with reduced risk for mortality. In total, 48 patients (24.1%) achieved LVRR and 45 (22.6%) achieved LV full recovery. LVEF <25% at baseline (HR: 0.66; 95% CI: 0.47 to 0.92) and regular use of beta-blockers at 6-month follow-up (HR: 1.62; 95% CI: 1.17 to 2.25) independently determined the risk for LV full recovery. Progressive reverse remodeling of all cardiac chambers was observed. In total, 18 patients (7.4%) were hospitalized during the study. CONCLUSIONS This is the largest study of PPCM in Africa. Consistent with late presentations, the mortality rate was high, whereas frequencies of LVRR and LV full recovery were low. Several variables predicted poor outcomes, and regular use of beta-blockers correlated with late survival and LV functional recovery.

Abstract
Peripartum cardiomyopathy (PPCM) is a condition in which heart failure and systolic dysfunction occur late in pregnancy or within months following delivery. Over the last decade, genetic advances in heritable cardiomyopathy have provided new insights into the role of genetics in PPCM. In this review, we summarise current knowledge of the genetics of PPCM and potential avenues for further research, including the role of molecular chaperone mutations in PPCM. Evidence supporting a genetic basis for PPCM has emanated from observations of familial disease, overlap with familial dilated cardiomyopathy, and sequencing studies of PPCM cohorts. Approximately 20% of PPCM patients screened for cardiomyopathy genes have an identified pathogenic mutation, with TTN truncations most commonly implicated. As a stress-associated condition, PPCM may be modulated by molecular chaperones such as heat shock proteins (Hsps). Recent studies have led to the identification of Hsp mutations in a PPCM model, suggesting that variation in these stress-response genes may contribute to PPCM pathogenesis. Although some Hsp genes have been implicated in dilated cardiomyopathy, their roles in PPCM remain to be determined. Additional areas of future investigation may include the delineation of genotype-phenotype correlations and the screening of newly-identified cardiomyopathy genes for their roles in PPCM. Nevertheless, these findings suggest that the construction of a family history may be advised in the management of PPCM and that genetic testing should be considered. A better understanding of the genetics of PPCM holds the potential to improve treatment, prognosis, and family management.

Abstract
Background Peripartum cardiomyopathy (PPCM) is an idiopathic cardiomyopathy presenting with acute heart failure during the peripartum period. It is common in patients of African ancestry. Currently, there is paucity of data on the burden, predictors and outcomes of PPCM in Uganda. This study aimed to investigate the prevalence, predictors and six-month outcomes of PPCM in an adult cohort attending a tertiary specialised cardiology centre in Kampala, Uganda. Methods This study consecutively enrolled 236 women presenting with features of acute heart failure in the peripartum period. Clinical evaluation and echocardiography were performed on all the enrolled women. PCCM was defined according to recommendations of the Heart Failure Association of the European Society of Cardiology Working Group on PPCM. Poor outcome at six months of follow-up was defined as presence of any of the following: death of a mother or her baby, New York Heart Association (NYHA) functional class III-IV or failure to achieve complete recovery of left ventricular function (left ventricular ejection fraction ≤55%). Results The median age, BMI and parity of the study participants was 31.5 (25.5–38.0) years, 28.3 (26.4–29.7) and 3 (2–4) respectively. The prevalence of PPCM was 17.4% (n = 41/236). Multiple pregnancy was the only predictor of PPCM in this study population (OR 4.3 95% CI 1.16–16.05, p = 0.029). Poor outcome at six-months was observed in about 54% of the patients with PPCM (n = 4, 9.8% in NYHA functional class III-IV and n = 22, 53.7% with LVEF <55%). No maternal or foetal mortality was documented. Conclusion PPCM is relatively common in Uganda and is associated with multiple pregnancy. Poor outcomes especially absence of complete recovery of left ventricular function are also common. Large studies to further investigate long-term maternal and foetal outcomes in Uganda are justified.

Abstract
Background We studied the efficacy and safety of selenium supplementation in patients who had peripartum cardiomyopathy (PPCM) and selenium deficiency. Methods We randomly assigned 100 PPCM patients with left ventricular ejection fraction (LVEF) < 45% and selenium deficiency (< 70 μg/L) to receive either oral Selenium (L-selenomethionine) 200 μg/day for 3 months or nothing, in addition to recommended therapy, in an open-label randomised trial. The primary outcome was a composite of persistence of heart failure (HF) symptoms, unrecovered LV systolic function (LVEF < 55%) or death from any cause. Results Over a median of 19 months, the primary outcome occurred in 36 of 46 patients (78.3%) in the selenium group and in 43 of 54 patients (79.6%) in the control group (hazard ratio [HR] 0.69; 95% confidence interval [CI] 0.43–1.09; p = 0.113). Persistence of HF symptoms occurred in 18 patients (39.1%) in the selenium group and in 37 patients (68.5%) in the control group (HR 0.53; 95% CI 0.30–0.93; p = 0.006). LVEF < 55% occurred in 33 patients (71.7%) in the selenium group and in 38 patients (70.4%) in the control group (HR 0.91; 95% CI 0.57–1.45; p = 0.944). Death from any cause occurred in 3 patients (6.5%) in the selenium group and in 9 patients (16.7%) in the control group (HR 0.37; 95% CI 0.10–1.37; p = 0.137). Conclusions In this study, selenium supplementation did not reduce the risk of the primary outcome, but it significantly reduced HF symptoms, and there was a trend towards a reduction of all-cause mortality.

Abstract
Aims The aim of this study was to describe the incidence, clinical characteristics and risk factors of peripartum cardiomyopathy (PPCM) in Nigeria. Methods and Results The study was conducted in 22 hospitals in Nigeria, and PPCM patients were consecutively recruited between June 2017 and March 2018. To determine factors associated with PPCM, the patients were compared with apparently healthy women who recently delivered, as controls. Four hundred six patients were compared with 99 controls. The incidence and disease burden (based on the rate of consecutive recruitment of subjects) varied widely between the six geographical zones of Nigeria. From the North–West zone, 72.3% of the patients was recruited, where an incidence as high as 1 per 96 live births was obtained in a centre, while the disease was uncommon (7.6% of all recruited patients) in the South. Majority of the patients (76.6%) and controls (74.8%) (p = 0.694) were of Hausa–Fulani ethnic group. Atrial fibrillation, intracardiac thrombus, stroke, and right ventricular systolic dysfunction were found in 1.7%, 6.4%, 2.2%, and 54.9% of the patients, respectively. Lack of formal education (odds ratio [OR] 3.08, 95% confidence interval [1.71, 5.53]; P < 0.001), unemployment (OR: 3.28 [2.05, 5.24]; P < 0.001), underweight (OR: 13.43 [4.17, 43.21]; P < 0.001) and history of pre‐eclampsia (OR: 9.01 [2.18, 37.75]; P = 0.002) emerged as independent PPCM risk factors using regression models. Customary hot baths (OR: 1.24 [0.80, 1.93]; P = 0.344), pap enriched with dried lake salt (OR: 1.20 [0.74, 1.94]; P = 0.451), and Hausa–Fulani ethnicity (OR: 1.11 [0.67, 1.84]; P = 0.698) did not achieve significance as PPCM risk factors. Conclusions In Nigeria, the burden of PPCM was greatest in the North–West zone, which has the highest known incidence. PPCM was predicted by sociodemographic factors and pre‐eclampsia, which should be considered in its control at population level. Postpartum customary birth practices and Hausa–Fulani ethnicity were not associated with PPCM in Nigeria.
