Pulsatile hemodynamics analyses provide important information about the ventricular-arterial system which cannot be inferred by standard blood pressure measurements. Pulse wave analysis (PWA), wave separation analysis (WSA), and wave power analysis (WPA) characterize arterial hemodynamics with limited preclinical applications. Integrating these tools into preclinical testing may enhance understanding of disease or therapeutic effects on cardiovascular function. We used a canine rapid ventricular pacing (RVP) heart failure model to: (1) Characterize hemodynamics in response to RVP and (2) assess analyses from flow waveforms synthesized from pressure compared to those derived from measured flow...

Background. The pulse characteristics of arterial circulation might affect radial artery catheterization's success rate. Therefore, we hypothesized that the success rate of radial artery catheterization would be lower in the left-sided severe stenotic valvular lesion group than severe regurgitant valvular lesion group. Methods. This prospective study was conducted among patients with left-sided cardiac valvular lesions undergoing cardiac and non-cardiac surgery. The patients with left-sided severe valvular stenosis and left-sided severe valvular regurgitation were included in the study...

Patients with rheumatoid arthritis (RA) have a much higher incidence of cardiac dysfunction, which contributes to the high mortality rate of RA despite anti-arthritic drug therapy. In this study, we investigated dynamic changes in cardiac function in classic animal models of RA and examined the potential effectors of RA-induced heart failure (HF). Collagen-induced arthritis (CIA) models were established in rats and mice. The cardiac function of CIA animals was dynamically monitored using echocardiography and haemodynamics...

Dilated cardiomyopathy (DCM) is a common cause of heart failure, and males are more likely to suffer from DCM than females. This research aimed at exploring possible DCM-associated genes and their latent regulatory effects in female and male patients. WGCNA analysis found that in the yellow module, 341 and 367 key DEGs were identified in females and males, respectively. A total of 22 hub genes in females and 17 hub genes in males were identified from the PPI networks of the key DEGs based on Metascape database...

BACKGROUND: Studies revealing the relationship between major surgery outcomes and nutritional parameters are increasing daily. Publications demonstrating the relationship between early postoperative success and surgical complications in patients with chronic heart failure and continuous flow left ventricular assist device (cf-LVAD) are limited. The vast majority of patients with advanced chronic heart failure are cachexic, and the reason for this is multifactorial. The aim of this study is to investigate the link between the modified nutritional risk index (NRI) and 6-month survival and complication rates in patients with a cf-LVAD...

Cardiac amyloidosis was thought to be rare, undiagnosable, and incurable. However, recently it has been discovered to be common, diagnosable, and treatable. This knowledge has led to a resurgence in nuclear imaging with 99m Tc-pyrophosphate-a scan once believed to be extinct-to identify cardiac amyloidosis, particularly in patients with heart failure but preserved ejection fraction. The renewed interest in 99m Tc-pyrophosphate imaging has compelled technologists and physicians to reacquaint themselves with the procedure...

Cardiac amyloidosis (CA) is an infiltrative cardiomyopathy resulting from deposition of insoluble amyloid protein in the myocardial interstitium. The accumulation of amyloid protein causes the myocardium to thicken and stiffen, leading to diastolic dysfunction and, eventually, heart failure. Two primary types of amyloidosis-transthyretin and immunoglobulin light chain-account for nearly 95% of all CA diagnoses. Three case studies are presented. The first demonstrates a patient positive for transthyretin amyloidosis, the second demonstrates a patient positive for light-chain CA, and the third demonstrates a patient showing blood-pool uptake on the [99m Tc]Tc-pyrophosphate scan but negative for CA...

Cardiac amyloidosis is a systemic form of amyloidosis in which protein-based infiltrates are deposited in myocardial extracellular space. The accumulation of amyloid fibrils causes the myocardium to thicken and stiffen, leading to diastolic dysfunction and, eventually, heart failure. Until recently, cardiac amyloidosis was considered rare. However, the recent adoption of noninvasive diagnostic testing, including 99m Tc-pyrophosphate imaging, has revealed a previously undiagnosed sizable disease prevalence. Light-chain amyloidosis (AL) and transthyretin amyloidosis (ATTR), the 2 primary types, account for 95% of cardiac amyloidosis diagnoses...

ETHNOPHARMACOLOGICAL RELEVANCE: Traditional Chinese medicine theory believes that qi deficiency and blood stasis are the key pathogenesis of heart failure with preserved ejection fraction (HFpEF). As a representative prescription for replenishing qi and activating blood, QiShenYiQi dripping pills (QSYQ) has been used for treating heart diseases. However, the pharmacological mechanism of QSYQ in improving HFpEF is not well understood. AIM OF THE STUDY: The objective of the study is to investigate the cardioprotective effect and mechanism of QSYQ in HFpEF using the phenotypic dataset of HFpEF...

Heart failure is a critical and ultimate phase of cardiovascular ailment that leads to a considerable incidence of disability and mortality. Among various factors contributing to heart failure, myocardial infarction is one of the most frequent and significant causes, which is still difficult to manage effectively. An innovative therapeutic strategy, namely a 3D bio-printed cardiac patch, has recently emerged as a promising approach to substitute damaged cardiomyocytes in a localized infarct region. Nevertheless, the efficacy of this treatment primarily relies on the long-term viability of the transplanted cells...

Tocilizumab (TCZ), an IL-6 inhibitor, has shown promise in the treatment of donor-specific antibodies (DSA) and chronic antibody-mediated rejection (AMR) in renal transplant recipients. However, its use in lung transplantation has not been described. This retrospective case-control study compared AMR treatments containing TCZ in nine bilateral lung transplant recipients to 18 patients treated for AMR without TCZ. Treatment with TCZ resulted in more clearance of DSA, lower recurrence of DSA, lower incidence of new DSA, and lower rates of graft failure when compared to those treated for AMR without TCZ...

Heart failure demographics have evolved in past decades with the development of improved diagnostics, therapies and prevention. Cardiac magnetic resonance (CMR) has developed in a similar timeframe to become the gold-standard non-invasive imaging modality for characterising diseases causing heart failure. CMR techniques to assess cardiac morphology and function have progressed since their first use in the 1980s. Increasingly efficient acquisition protocols generate high spatial and temporal resolution images in shorter time frames...

OBJECTIVES: Contingency management (CM) is one of the most effective treatments for stimulant use disorder but has not been leveraged for people with stimulant-associated cardiomyopathy (SA-CMP), a chronic health condition with significant morbidity and mortality. We aimed to determine the feasibility and acceptability of a multidisciplinary addiction/cardiology clinic with CM for patients with SA-CMP and to explore barriers and facilitators to engagement and recovery. METHODS: We recruited patients with a hospitalization in the past 6 months, heart failure with reduced ejection fraction (<40%) and stimulant use disorder to participate in Heart Plus, a 12-week addiction/cardiology clinic with CM in an urban, safety-net, hospital-based cardiology clinic, which took place March 2021 through June 2021...
