Myocardial Insufficiency

Peripartum cardiomyopathy (PPCM) is an idiopathic myocardial insufficiency that occurs in the absence of any diagnosed heart disease during the last month of pregnancy or during the first 5 months after delivery. The aim. To improve immediate and long-term maternal outcomes in patients with PPCM by establishing an optimal strategy for its diagnosis, treatment, delivery and medical support during the postpartum period. Materials and methods. The article presents the experience of multidisciplinary medical care for 11 pregnant wo-men and postpartum women with dilated cardiomyopathy (DCM) on the basis of the National Amosov Institute of Cardio-vascular Surgery and the Institute of Pediatrics, Obstetrics and Gynecology named after acad. O. M. Lukianova of NAMS of Ukraine. After the differential diagnosis, 8 women were defined as patients with PPCM, and 3 women had family history of the disease (DCM in relatives). All the patients were examined according to the protocol using the history, examination, and instrumental and laboratory findings. Results. After in-hospital treatment there was an increase in the left ventricular ejection fraction (LVEF) in the group of patients with PPCM from 28.3 ± 9.3% to 37.6 ± 7.6% and a decrease in end-diastolic volume (EDV) from 196.7 ± 47.7 ml to 181.3 ± 59.7 ml, end-systolic volume (ESV) from 104.25 ± 33.3 ml to 94.2 ± 35.1 ml. In four cases, patients with severe left ventricular (LV) dysfunction underwent urgent preterm Cesarean section in the second trimester of pregnancy. There were no early maternal losses, there were two perinatal losses of extremely premature infants (16 and 27 weeks of gesta-tion). In the follow-up period (23.5 ± 11.6 months), LVEF further increased up to 42.9 ± 8.4% and EDV and ESV decreased up to 170.1 ± 49.5 and 82.7 ± 40.6 ml, respectively. In 7 (87.5%) patients with PPCM, a significant improvement in clini-cal condition and pumping function of the heart was registered at the time of discharge from the hospital, and there was further improvement in the indicators for another 12 months, but complete recovery of cardiac function was achieved only in 3 (37.5%) patients. In patients from the group of family type DCM, complete recovery of LV myocardial function was not observed in any of the 3 studied cases. The article discusses the timing of the occurrence and diagnosis of PPCM, the main clinical, instrumental and labora-tory signs of the pathology, methods of cardiological, cardiosurgical and obstetric support of such pregnant women. Conclusions. The terms of the onset of PPCM manifestations may be wider (earlier) according to our observations and should be the subject of further research. The strategy of medical care for pregnant women doesn’t particularly depend on the type of DCM. However, obstetric tactics aimed at early delivery of a patient with PPCM with severe myocardial insufficiency are feasible in combination with interruption of lactation and in most cases allow to achieve compensation of circulation and partial recovery of LV function. Prescription of bromocriptine for this purpose seems appropriate. The use of repeated courses of levosimendan in patients with PPCM is feasible and helps to improve the LV function in the early postpartum period.

Abstract Background The aim of this study was to explore the risk factors associated with a poor left ventricular (LV) function among patients with peripartum cardiomyopathy (PPCM) and to determine the influence of acute kidney injury (AKI) on the LV function of the patients. Methods Sixty patients with PPCM were recruited between January 2007 and June 2018, among which 11 had AKI. The participants were divided into two groups, the recovery group (32 cases) and the nonrecovery group (28 cases), with their clinical features, echocardiography and electrocardiogram findings, laboratory results, and treatments compared between groups. We further determined the risk factors associated with nonrecovery and the influence posed by AKI on the LV function of the patients. Results Compared with the patients in the recovery group, those in the nonrecovery group had higher proportions of multiparity [78.6% (22/28) vs. 43.8% (14/32)], function class III– IV heart failure [92.9% (26/28) vs. 71.9% (23/32)], and a higher incidence of AKI [35.7% (10/28) vs. 3.1% (1/32)]. Logistic regression analysis showed that having AKI [odds ratio (OR): 10.556; 95% confidence interval (CI) 1.177–94.654; P = 0.035] and left ventricular ejection fraction (LVEF) < 40% [OR: 4.533; 95% CI 1.118–18.382; P = 0.034] were independently associated with nonrecovery of PPCM. Conclusions The prognosis of patients with PPCM and AKI during hospitalization was poor compared to those without AKI; therefore, clinicians should pay more attention to this phenomenon.

Emergent Cesarean Section

Perioperative management of pregnant women with heart failure is difficult. Management of anesthesia in pregnant women is especially difficult because all of the currently available choices present challenges. We report a patient with peripartum cardiomyopathy (PPCM) who required an emergent cesarean section and discuss the possible tactics for managing anesthesia. A 40-year-old primipara with severe cardiac and respiratory failure required an emergent cesarean section at 39+1 gestational weeks. Her left ventricular ejection fraction was between 10% and 15%, and she had orthopnea. General anesthesia was planned after inserting sheaths for percutaneous cardiopulmonary support from the femoral artery and vein. However, when the patient was asked to lie down on the operation bed, she panicked and resisted because of labor pain and dyspnea. Therefore, anesthesia was induced instead of the initial plan. Finally, we successfully managed the anesthesia and delivered the newborn. There are no alternatives to general anesthesia in patients with PPCM presenting with orthopnea. Anesthesia induction in the supine position is impossible in such patients owing to dyspnea. Anesthesia should be started with light sedation in the sitting position, and ketamine or low-dose remifentanil may be an option to maintain maternal hemodynamics and prevent neonatal asphyxia.

Abstract Introduction Peripartum cardiomyopathy (PPCM) is an important cause of pregnancy-associated heart failure worldwide. Although a significant number of women recover their left ventricular (LV) function within 12 months, some remain with persistently reduced systolic function. Methods Knowledge gaps exist on predictors of myocardial recovery in PPCM. N-terminal pro-brain natriuretic peptide (NT-proBNP) is the only clinically established biomarker with diagnostic value in PPCM. We aimed to establish whether NT-proBNP could serve as a predictor of LV recovery in PPCM, as measured by LV end-diastolic volume (LVEDD) and LV ejection fraction (LVEF). Results This study of 35 women with PPCM (mean age 30.0 ± 5.9 years) had a median NT-proBNP of 834.7 pg/ml (IQR 571.2–1840.5) at baseline. Within the first year of follow-up, 51.4% of the cohort recovered their LV dimensions (LVEDD < 55 mm) and systolic function (LVEF > 50%). Women without LV recovery presented with higher NT-proBNP at baseline. Multivariable regression analyses demonstrated that NT-proBNP of ≥ 900 pg/ml at the time of diagnosis was predictive of failure to recover LVEDD (OR 0.22, 95% CI 0.05–0.95, P = 0.043) or LVEF (OR 0.20 [95% CI 0.04–0.89], p = 0.035) at follow-up. Conclusions We have demonstrated that NT-proBNP has a prognostic value in predicting LV recovery of patients with PPCM. Patients with NT-proBNP of ≥ 900 pg/ml were less likely to show any improvement in LVEF or LVEDD. Our findings have implications for clinical practice as patients with higher NT-proBNP might require more aggressive therapy and more intensive follow-up. Point-of-care NT-proBNP for diagnosis and risk stratification warrants further investigation.

Abstract Background Peripartum cardiomyopathy (PPCM) is usually characterized by overt heart failure, but other clinical scenarios are possible, sometimes making the diagnosis challenging. Case summary We report a case series of four patients with PPCM. The first patient presented with acute heart failure due to left ventricular (LV) systolic dysfunction. Following medical treatment, LV function recovered completely at 1 month. The second patient had systemic and pulmonary thromboembolism, secondary to severe biventricular dysfunction with biventricular thrombi. The third patient presented with myocardial infarction with non-obstructed coronary arteries and evidence of an aneurysm of the mid-anterolateral LV wall. The fourth patient, diagnosed with PPCM 11 years earlier, presented with sustained ventricular tachycardia. A repeat cardiac magnetic resonance, compared to the previous one performed 11 years earlier, showed an enlarged LV aneurysm in the mid-LV anterolateral wall with worsened global LV function. Discussion Peripartum cardiomyopathy may have different clinical presentations. Attentive clinical evaluation and multimodality imaging can provide precise diagnostic and prognostic information.

AbstractTo evaluate the effect of age and parity on maternal cardiac diastolic function in second trimester among pregnant women with normal left ventricular ejection fraction. To analyze the correlation between impaired diastolic function and pre-eclampsia. It had been suggested that maternal cardiac adaptations during pregnancy differed between nulliparous and primiparous women and also varied according to age. Impaired cardiac function may precede pre-eclampsia. Therefore, we examined the effects of parity and age on cardiac diastolic function during pregnancy and whether impaired diastolic function during the second trimester correlates with pre-eclampsia. Women with singleton pregnancies at 13 + 0 to 27 + 6 weeks’ gestation and left ventricular ejection fraction (LVEF) ≥ 50% were retrospectively identified. Diastolic function parameters were assessed using transthoracic echocardiography. Pre-eclampsia was identified from medical records. The effect of age and parity on maternal cardiac diastolic function as well as the correlation between impaired diastolic function and occurrence rate of pre-eclampsia were examined. 376 pregnant women were included (median age: 30 years; median gestational age: 14 weeks; 171 primiparous women). LVEF was 66%. Impaired cardiac diastolic function was seen in 7.8% of pregnant women < 35 years compared with 28.6% of those ≥ 35 years (p = 0.000). ROC curve showed women with maternal age over 32 began to have a higher rate of impaired cardiac diastolic function (AUC = 0.704, p = 0.000, sensitivity = 54.5%, specificity = 75.3%). There was no difference in diastolic function indices between maternal women grouped by parity. Higher maternal age was an independent risk factor of declining Em (p < 0.05). Em < 13 cm/s was significantly associated with pre-eclampsia occurrence (HR 8.56; 95% CI 3.40–21.57) after being adjusted for confounders. Maternal age is an independent risk factor for diastolic function decline. There is no difference in cardiac diastolic function between nulliparous women and primiparous women. Pre-eclampsia occurrence is significantly higher in patients with impaired diastolic function at mid-gestation. The application of risk grading using diastolic function at mid-gestation may improve the survival outcomes of pregnant women.

Abstract Funding Acknowledgements Type of funding sources: None. Background  The diagnosis of atrial fibrillation (AF) induced cardiomyopathy can be challenging. It relies on ruling out other causes of dilated cardiomyopathy, upon recovery of left ventricular ejection fraction (LVEF) following return to sinus rhythm (SR). Aim  The aim of this study was to identify clinical and echocardiographic predictors for developing new dilated cardiomyopathy in patients with AF or atrial flutter (AFL). Methods  This is a retrospective study conducted in a large tertiary care center. Patients that suffered deterioration of LVEF under 50% during AF demonstrated by pre-cardioversion trans-esophageal echocardiography (TEE) were compared to those with preserved LV function during AF. All patients had documented preserved LVEF at baseline (EF &gt;50%) while in SR. Patients with a previous history of reduced LVEF during SR were excluded. Results From a total of 482 patients included in the final analysis, 80 (17%) patients had reduced LV function and 402 (83%) had preserved LV function during the pre-cardioversion TEE. Patients with reduced LVEF were more likely to be male and with a more rapid ventricular response during AF/AFL. A history of prosthetic valves was also identified as a risk factor for reduced LVEF. Patients with reduced LVEF also had higher incidence of TR and RV dysfunction. Conclusion In "real world" experience, male patients with rapid ventricular response during AF or AFL are more prone to LVEF reduction. Patients with prosthetic valves are also at risk for LVEF reduction during AF/AFL. Lastly, TR and RV dysfunction may indicate relatively long-standing AF with an associated reduction in LVEF.

Background: The concept of ventricular-arterial coupling implies that LV-function is determined by the three factors left ventricular diastolic, left ventricular systolic and arterial elastance. We have previously documented an improvement in endothelial function and systolic LV-function in patients with chronic heart failure (CHF) after 6 months of exercise training (ET). It remains, however, unclear, how shorter ET periods may affect endothelial, systolic and diastolic ventricular function as echocardiographic parameters related to ventricular arterial coupling in patients with CHF. METHODS: In this ongoing study we randomised 43 patients with stable CHF (age 60.3 ± 2.9 years, EF 27.4 ± 1.7%, VO 2 max 14.7 ± 4.3ml/kg*min) to a training or a control group (C). Patients in the training group exercised 4 times daily at 70% of the individual heart rate reserve for 4 weeks under supervision. At baseline and after 4 weeks the E/A ratio and septal/lateral E’/A’ velocities were determined by echocardiography with tissue Doppler. Exercise capacity was measured by ergospirometry and flow-mediated dilatation (FMD) was assessed by high-resolution radial ultrasound. RESULTS: After only 4 weeks of ET oxygen uptake at peak exercise increased from 14.9 ± 3.3 to 18.1 ± 4.7 ml/min/kg, (p<0.01 vs. C) in training subjects. Left ventricular ejection fraction improved from 26.8 ± 4.6 to 33.1 ± 5.5% (p<0.05 vs. C) in patients of the training group while it remained unchanged in the control group. E/A-ratio mended from 0.63 ± 0.12 to 0.81 ± 0.22 (p<0.01 vs. C) in training patients. Septal E’ velocities increased from 5.5 ± 0.5 to 7.8 ± 1.4 cm/s in training patients (p<0.05 vs. C). FMD of the radial artery improved from 8.2 ± 2.1 to 15.2 ± 3.8% (p<0.01 vs. C) as a result of ET. CONCLUSIONS: Only 4 weeks of endurance training are highly effective with significantly improved FMD accompanied by an emended systolic and diastolic LV-function. We hypothesise that the improvement in LV-EF in training patients may be caused by a corrected ventricular-arterial coupling: ventricular diastolic relaxation and effective endothelial function are ameliorated resulting in an augmentation of stroke volume.

Introduction: Preterm (PT) birth is associated with increased risk of cardiovascular diseases (CVD) and heart failure. We previously reported left ventricular (LV) mitochondrial dysfunction in a rat model mimicking the deleterious conditions associated with PT birth. Whether mitochondrial function is altered in humans born PT and associated with LV function changes is unknown. We aimed to determine if serum humanin levels, a mitochondrial-derived peptide with cytoprotective effects, are altered in humans born PT and are associated with impaired myocardial function. Methods: Data were obtained from 55 young adults born PT (<30 weeks of gestational age, GA) compared to 54 full-term (T) controls of the same age. Serum humanin levels were determined by ELISA and LV ejection fraction (LVEF) by echocardiography. Results are shown as median (interquartile range) and comparisons between groups were performed using non-parametric tests. Results: Individuals were evaluated at 23.3 (21.4, 25.3) years, and age and sex distribution were similar between groups. Median GA was 27.5 (26.2, 28.4) weeks in the PT group. Humanin levels (pg/ml) were 132.9 (105.1, 189.3) and 161.1 (123.6, 252) in the PT and the T groups, respectively (p=0.0414). LVEF was within the normal range and similar between groups. Lower LVEF was associated with lower humanin levels (p<0.001), and this association was observed both in the term (p=0.002) and the preterm (p=0.047) groups. Conclusions: Serum humanin levels are lower in adult born PT. Since lower humanin levels are also associated with lower LVEF, our results suggest that mitochondrial alterations could play a role in the long-term adverse cardiovascular consequences of PT birth. Humanin analogs improve LV function in experimental models. Our results pave the way for future studies exploring humanin as a therapeutic avenue for the prevention and treatment of CVD in individuals born PT.

Background: Cardiovascular functions and hemodynamics dramatically change during pregnancy such as cardiac output, expanded blood volume, reduced systematic vascular resistance, and heart chamber enlargement. Hypertensive disorders of pregnancy (HDP) may affect the cardiac load during pregnancy; however, the data about plasma concentration of cardiac troponin in pregnant women with HDP is very limited. Methods: We prospectively collected data of 751 pregnant women between 2012 and 2013 in Japanese general hospital. We analyzed laboratory data and echocardiographic findings after delivery. The elevated cTnI was defined as >0.015 ng/mL because the normal population have serum cTnI of less than 0.015 ng/mL in this assay. Results: The HDP were observed in 32 patients; the elevated cTnI was observed 40 patients. The age of patients with HDP (33.7 ±4.3 years) was not different from that of those without HDP (33.3 ± 5.0 years). The brain natriuretic peptides levels were not different between those with and without HDP. The proportion of elevated cTnI was higher in those with HDP (21.8%) than those without (3.6%, P<0.0001). After adjusting for confounders, the risk of elevated cTnI in those with HDP relative to those without HDP remained significant (odds ratio 4.52, 95% confidence interval 1.45-14.5). There were no women with reduced left ventricular ejection fraction. Conclusions: HDP was associated with elevated cTni, suggesting myocardial microinjury might occur more frequently in those with HDP.

Abstract Aims Cardiovascular disease is a major threat to maternal health, with cardiomyopathy being among the most common acquired cardiovascular diseases during pregnancy and the postpartum period. The aim of our study was to evaluate the effectiveness of an electrocardiogram (ECG)-based deep learning model in identifying cardiomyopathy during pregnancy and the postpartum period. Methods and Results We used an ECG-based deep learning model to detect cardiomyopathy in a cohort of women who were pregnant or in the postpartum period seen at Mayo Clinic. Model performance was evaluated using area under the receiver operating characteristic curve (AUC), accuracy, sensitivity, and specificity. We compared the diagnostic probabilities of the deep learning model with natriuretic peptides and a multivariable model consisting of demographic and clinical parameters. The study cohort included 1,807 women; 7%, 10%, and 13% had left ventricular ejection fraction (LVEF) of 35% or less, less than 45%, and less than 50%, respectively. The ECG-based deep learning model identified cardiomyopathy with AUCs of 0.92 (LVEF ≤35%), 0.89 (LVEF &lt;45%), and 0.87 (LVEF &lt;50%). For LVEF of 35% or less, AUC was higher in Black (0.95) and Hispanic (0.98) women compared to White (0.91). Natriuretic peptides and the multivariable model had AUCs of 0.85 to 0.86 and 0.72, respectively. Conclusions An ECG-based deep learning model effectively identifies cardiomyopathy during pregnancy and the postpartum period and outperforms natriuretic peptides and traditional clinical parameters with the potential to become a powerful initial screening tool for cardiomyopathy in the obstetric care setting.
