Jasińska-Stroschein M. An updated review of experimental rodent models of pulmonary hypertension and left heart disease. Front Pharmacol 2024; 14:1308095.

Abstract
Left heart disease (LHD) is the leading cause of pulmonary hypertension (PH). Its recent growth has not been matched by the design of therapeutic agents directly targeting the disease. Effective therapies approved for pulmonary arterial hypertension (PAH) have been shown to be inefficient in patients with PH-LHD. Hence, there is a need for an animal model that would closely mimic PH-LHD in preclinical experiments. The current study describes and compares a number of rodent models of left ventricular failure and their potential to induce PH. It also evaluates whether, and to what extent, common PH models could develop LV failure. Articles were identified in the Pubmed/Medline and Web of Science online electronic databases following the PRISMA Protocol between 1992 and 2022. Quality assessment was carried out using the SYRCLE risk-of-bias tool for animal studies. Publication bias across studies using Egger's regression test statistic, was performed together with sensitivity analysis. A wide spectrum of protocols-135 studies and 207 interventions, was examined, including systemic hypertensive models, pressure-overload-induced HF, model of ischemic heart failure, and metabolic approaches based on high fat diet or metabolic syndrome. The most pronounced alterations in PH-related parameters were demonstrated for the common PH models, but were also seen in animals with LV failure induced by ischemic conditions, pressure overload or metabolic conditions. Models based on aortic banding, transverse aortic constriction (TAC), or with myocardial infarction (MI) caused by coronary artery ligation, demonstrated more pronounced worsening in PH due to LV failure; however, they also demonstrated poor survival, especially the ischemic-HF model. Common PH models, excluding prolonged exposure to monocrotaline, do not promote LV hypertrophy. Prolonged exposure to a high-fat diet, or a two-hit model of an obese ZSF1 rat combined with SU5416-induced pulmonary endothelial impairment (a VEGF receptor antagonist) worsened PH and impaired diastolic dysfunction. Due to the limited number of protocols, further trials are needed to confirm the utility of such approaches for modeling PH in subjects with metabolic syndrome. This would provide a clearer insight into the complexity of LHD, PH and metabolic disorders in PH-LHD, and thus accelerate the development of new therapies in clinical trials.

Abstract
BACKGROUND The high incidence of atrial arrhythmias in pulmonary hypertension (PH) might be associated with poor prognosis, and the left atrium (LA) may play a role in this. An important finding in PH studies is that LA remodeling is underestimated. OBJECTIVE This study investigated LA morphology and mechanical function, as well as the susceptibility to develop arrhythmias in a monocrotaline-induced PH (MCT-PH) model. METHODS Wistar rats aged 4 weeks received 50 mg/kg of MCT. Electrocardiography and histology analysis were performed to evaluate the establishment of the MCT-PH model. The tissue was mounted in an isolated organ bath to characterize the LA mechanical function. RESULTS Compared with the control group (CTRL), the MCT-PH model presented LA hypertrophy and changes in cardiac electrical activity, as evidenced by increased P wave duration, PR and QT interval in MCT-PH rats. In LA isolated from MCT-PH rats, no alteration in inotropism was observed; however, the time to peak contraction was delayed in the experimental MCT-PH group. Finally, there was no difference in arrhythmia susceptibility of LA from MCT-PH animals after the burst pacing protocol. CONCLUSION The morphofunctional remodeling of the LA did not lead to increased susceptibility to ex vivo arrhythmia after application of the burst pacing protocol.

Abstract
Pulmonary hypertension due to left heart disease (PH-LHD) or group 2 PH is the most common and lethal form of PH, occurring secondary to left ventricular systolic or diastolic heart failure (HF), left-sided valvular diseases, and congenital abnormalities. It is subdivided into isolated postcapillary PH (IpcPH) and combined pre- and post-capillary PH (CpcPH), with the latter sharing many similarities with group 1 PH. CpcPH is associated with worse outcomes and increased morbidity and mortality when compared to IpcPH. Although IpcPH can be improved by treatment of the underlying LHD, CpcPH is an incurable disease for which no specific treatment exists, likely due to the lack of understanding of its underlying mechanisms. Furthermore, drugs approved for PAH are not recommended for group 2 PH, as they are either ineffective or even deleterious. With this major unmet medical need, a better understanding of mechanisms and the identification of effective treatment strategies for this deadly condition are urgently needed. This review presents relevant background of the molecular mechanisms underlying PH-LHD that could translate into innovative therapeutic targets and explores novel targets currently being evaluated in clinical trials.

Abstract
The development of pulmonary hypertension (PH) is common and has adverse prognostic implications in patients with heart failure due to left heart disease (LHD), and thus far, there are no known treatments specifically for PH-LHD, also known as group 2 PH. Diagnostic thresholds for PH-LHD, and clinical classification of PH-LHD phenotypes, continue to evolve and, therefore, present a challenge for basic and translational scientists actively investigating PH-LHD in the preclinical setting. Furthermore, the pathobiology of PH-LHD is not well understood, although pulmonary vascular remodeling is thought to result from (1) increased wall stress due to increased left atrial pressures; (2) hemodynamic congestion-induced decreased shear stress in the pulmonary vascular bed; (3) comorbidity-induced endothelial dysfunction with direct injury to the pulmonary microvasculature; and (4) superimposed pulmonary arterial hypertension risk factors. To ultimately be able to modify disease, either by prevention or treatment, a better understanding of the various drivers of PH-LHD, including endothelial dysfunction, abnormalities in vascular tone, platelet aggregation, inflammation, adipocytokines, and systemic complications (including splanchnic congestion and lymphatic dysfunction) must be further investigated. Here, we review the diagnostic criteria and various hemodynamic phenotypes of PH-LHD, the potential biological mechanisms underlying this disorder, and pressing questions yet to be answered about the pathobiology of PH-LHD.

Abstract
Pulmonary hypertension due to left heart disease (PH‐LHD) is regarded as the most prevalent form of pulmonary hypertension (PH). Indeed, PH is an independent risk factor and predicts adverse prognosis for patients with left heart disease (LHD). Clinically, there are no drugs or treatments that directly address PH‐LHD, and treatment of LHD alone will not also ameliorate PH. To target the underlying physiopathological alterations of PH‐LHD and to develop novel therapeutic approaches for this population, animal models that simulate the pathophysiology of PH‐LHD are required. There are several available models for PH‐LHD that have been successfully employed in rodents or large animals by artificially provoking an elevated pressure load on the left heart, which by transduction elicits an escalated pressure in pulmonary artery. In addition, metabolic derangement combined with aortic banding or vascular endothelial growth factor receptor antagonist is also currently applied to reproduce the phenotype of PH‐LHD. As of today, none of the animal models exactly recapitulates the condition of patients with PH‐LHD. Nevertheless, the selection of an appropriate animal model is essential in basic and translational studies of PH‐LHD. Therefore, this review will summarize the characteristics of each PH‐LHD animal model and discuss the advantages and limitations of the different models.

Abstract
First responders (FR) exposed to the World Trade Center (WTC) Ground Zero air over the first week after the 9/11 disaster have an increased heart disease incidence compared to unexposed FR and the general population. To test if WTC dusts were causative agents, rats were exposed to WTC dusts (under isoflurane [ISO] anesthesia) 2 h/day on 2 consecutive days; controls received air/ISO or air only. Hearts were collected 1, 30, 240, and 360 d post-exposure, left ventricle total RNA was extracted, and transcription profiles were obtained. The data showed that differentially expressed genes (DEG) for WTC vs. ISO rats did not reach any significance with a false discovery rate (FDR) < 0.05 at days 1, 30, and 240, indicating that the dusts did not impart effects beyond any from ISO. However, at day 360, 14 DEG with a low FDR were identified, reflecting potential long-term effects from WTC dust alone, and the majority of these DEG have been implicated as having an impact on heart functions. Furthermore, the functional gene set enrichment analysis (GSEA) data at day 360 showed that WTC dust could potentially impact the myocardial energy metabolism via PPAR signaling and heart valve development. This is the first study showing that WTC dust could significantly affect some genes that are associated with the heart/CV system, in the long term. Even > 20 years after the 9/11 disaster, this has potentially important implications for those FR exposed repeatedly at Ground Zero over the first week after the buildings collapsed.

Abstract
Introduction:
Animal models have been used to understand the pathophysiology of
pulmonary hypertension, to describe the mechanisms of action and to evaluate promising active
ingredients. The monocrotaline-induced pulmonary hypertension model is the most used animal
model. In this model, invasive and non-invasive hemodynamic variables that resemble human
measurements have been used. Aim: To define if non-invasive variables can predict hemodynamic
measures in the monocrotaline-induced pulmonary hypertension model.
Materials and Methods:
Twenty 6-week old male Wistar rats weighing between 250-300g from the
bioterium of the Universidad del Valle (Cali - Colombia) were used in order to establish that the
relationships between invasive and non-invasive variables are sustained in different conditions
(healthy, hypertrophy and treated). The animals were organized into three groups, a control group
who was given 0.9% saline solution subcutaneously (sc), a group with pulmonary hypertension
induced with a single subcutaneous dose of Monocrotaline 30 mg/kg, and a group with pulmonary
hypertension with 30 mg/kg of monocrotaline treated with Sildenafil. Right ventricle ejection
fraction, heart rate, right ventricle systolic pressure and the extent of hypertrophy were measured.
The functional relation between any two variables was evaluated by the Pearson correlation
coefficient.
Results:
It was found that all correlations were statistically significant (p <0.01). The strongest
correlation was the inverse one between the RVEF and the Fulton index (r = -0.82). The Fulton index
also had a strong correlation with the RVSP (r = 0.79). The Pearson correlation coefficient between
the RVEF and the RVSP was -0.81, meaning that the higher the systolic pressure in the right
ventricle, the lower the ejection fraction value. Heart rate was significantly correlated to the other
three variables studied, although with relatively low correlation.
Conclusion:
The correlations obtained in this study indicate that the parameters evaluated in the
research related to experimental pulmonary hypertension correlate adequately and that the
measurements that are currently made are adequate and consistent with each other, that is, they have
good predictive capacity.

Abstract
OBJECTIVE This contemporary study sought to describe the outcomes of patients undergoing biventricular repair of infracardiac total anomalous pulmonary venous connection. METHODS A retrospective study was performed on patients with infracardiac total anomalous pulmonary venous connection who underwent sutureless technique or conventional repair between 2006 and 2018. Risk factors for survival and post-repair pulmonary vein stenosis (PVS) were assessed with Cox regression model. Time-to-event analysis was conducted using Kaplan-Meier estimates. RESULTS This study included 82 consecutive patients with the median age of 21 days (interquartile range, 9-40 days). The median follow-up was 29 months (interquartile range, 12.5-59 months) and was available in 95% of the survivors at the end of the study period in 2019. Overall, 8 deaths (8.5%) occurred in the conventional repair group. There was a trend of higher mortality in the conventional repair group, although it did not reach a statistical difference (P = .2). Postrepair PVS occurred at a median of 2 months (interquartile range, 1.2-3.6 months) postoperatively and all occurred in the conventional repair group. Time-to-event analysis with the event of postrepair PVS showed significantly higher freedom from restenosis in the sutureless technique group (P = .0004). Adjusted hazard ratios from time-dependent Cox model described the association between postrepair PVS and pulmonary venous confluence of antler configuration (hazard ratio, 2.14; 95% confidence interval, 1.03-5.47; P = .002) and the use of sutureless technique (hazard ratio, 0.72; 95% confidence interval, 0.39-0.97; P = .003). CONCLUSIONS Sutureless technique is associated with a lower risk of postrepair PVS in patients with infracardiac total anomalous pulmonary venous connection. pulmonary venous confluence configuration of antler appearance appears to be associated with restenosis and mortality.

Abstract
Left heart disease is the main cause of clinical pulmonary arterial hypertension (PAH). Common types of left heart disease that result in PAH include heart failure, left ventricular systolic dysfunction, left ventricular diastolic dysfunction and valvular disease. It is currently believed that mechanical pressure caused by high pulmonary venous pressure is the main cause of myocardial infarction (MI) in individuals with ischemic cardiomyopathy and left ventricular systolic dysfunction. In the presence of decreased cardiac function, vascular remodeling of pulmonary vessels in response to long-term stimulation by high pressure in turn leads to exacerbation of PAH. However, the underlying pathological mechanisms remain unclear. Elucidating the association between the development of MI and PAH may lead to a better understanding of potential risk factors and better disease treatment. In this article, the pathophysiological effects of multiple systems in individuals with MI and PAH were reviewed in order to provide a general perspective on various potential interactions between cardiomyocytes and pulmonary vascular cells.
