Abstract
Abstract
Background
Myocardial dysfunction is well established in systemic sclerosis (SSc). The utility of standard echocardiography is limited to detect the onset of myocardial dysfunction. Speckle tracking echocardiography (STE) and strain imaging has emerged as a useful technique to quantify left ventricle hemodynamics and myocardial function in early stages of myocardial dysfunction. We aimed to systematically analyze the existing literature on the application of STE and strain analysis in identifying SSc associated myocardial dysfunction
Methods
PubMed, Cochrane, and Google Scholar were queried for studies from the inception of the databases to 2022. Case control studies that used 2D STE for assessment of strain in SSc patients and controls, were included for the analysis. PRISMA guidelines were followed for selections of studies. Two independent reviewers extracted data. Analysis was done using Cochrane Review Manager 5.0.
Results
Total of 19 studies were included in the analysis that compared strain analysis in SSc patient's vs healthy controls. Of the 16 studies that reported left ventricular (LV) global longitudinal strain, we found significantly lower LV global longitudinal strain in SSc patients (mean difference 1.92; 95% CI 0.98–2.87). Six studies reported LV circumferential strain which was noted to be lower in SSc patients compared to healthy controls (mean difference 3.55; 95% CI 1.60–5.51). Five studies reported LV global radial strain with a similar decrease in radial strain among SSc patients compared to controls (mean difference 4.39; 95% CI −6.95 to −1.83). 10 studies reported right ventricular longitudinal strain with a decrease in longitudinal strain in SSc patient's vs controls (mean difference 2.57; 95% CI 2.03–3.12).
Conclusions
SSc patients have lower strain values compared to controls, which is suggestive of an impaired myocardial function in left and right ventricle. Strain analysis by STE could help with early detection of myocardial dysfunction.

Abstract
Abstract
Background
Recent research has suggested a potential role of autoimmunity and inflammation in Takotsubo's cardiomyopathy (TC) [1]. There have been few reports of TC occurring in patients with pre-existing autoimmune diseases (AID). It has also been hypothesised that the low prevalence of TC in patients with AID might be due to attenuating effect on the inflammatory response to catecholamine excess in TC by immunosuppressive medications used in AID patients [2]. On a population-based level, the prevalence of AID in TC patients and its implications remain unknown.
Purpose
Using a large national database, we aimed to describe the prevalence of AID in TC patients and its impact on in-hospital outcomes of TC patients.
Methods
We performed a retrospective analysis using the 2016–2019 National inpatient sample database in the United States, covering over 7 million admissions per year. Using ICD-10 codes, we identified patients with TC and a concomitant diagnosis of any of the AID† depicted in Table 1. We compared TC patients with (AID+) and without AID (AID−) for patient characteristics and in-hospital outcomes. Our primary outcome of interest was mortality. Secondary outcomes are listed in Table 2. Linear regression and multivariate logistic regression analysis were done using STATA 17 to adjust for confounders.
Results
158,230 patients were admitted with TC and of those, 2880 (1.8%) had concomitant AID. Systemic lupus erythematosus (n=1515, 54.1%) was the most common AID followed by Sjogren's syndrome (n=645, 23.02%) Systemic sclerosis (n=440, 14%) and Rheumatoid Arthritis (n=200, 7.1%) in TC population. Compared to TC patients without AID, AID+ patients were relatively younger (mean age of 63 vs 67 years, p<0.0001) and more likely to be females (95% vs 83%, p<0.0001*). 200 (7.1%) and 9459 (6.08%) TC patients with and without AID died during hospitalisation,respectively. TC patients with AID had lower odds of developing acute decompensated heart failure [ADHF] (aOR=0.69 95% CI: 0.56–0.85, p=0.001*) and acute stroke (aOR=0.60, 95% CI: 0.43–0.85, p=0.005*) There was no statistical significance in mortality, rates of acute respiratory failure, cardiogenic shock and healthcare utilisation (Table 2).
Conclusion
Our study notes a substantially higher number of TC patients with pre-existing AID than previously reported in the literature. In addition, these patients have lower odds of developing acute stroke and ADHF, while there was no significant difference for cardiogenic shock and mortality. Further studies are required to decipher the potential link between AID and TC and explore the possible role of immunosuppressants in TC therapy, as suggested in prior studies.
*P-value <0.05 was considered statistically significant. aOR = Adjusted Odds Ratio. †AID included in the study are mentioned in Table 1.

Abstract
Abstract
Introduction
The incidence of heart failure has exponentially increased over the last few decades and acute decompensated diastolic heart failure is one of the leading causes of hospitalization and readmission. Cardiac amyloidosis is one of the rapidly progressing heart conditions. It occurs due to amorphous proteinaceous material called amyloid into the extracellular space of the heart. The infiltration of the heart from amyloid protein has a broad spectrum of presentation, including diastolic heart failure.
Purpose
Heart failure due to amyloidosis is characterized by diastolic dysfunction resulting from restrictive cardiomyopathy. The outcomes of hospitalized patient with acute decompensated diastolic heart failure in amyloidosis patients compared to those without amyloidosis is not well defined.
Methods
We conducted a retrospective cohort study by utilizing the National Inpatient sample database from 2017. Using International Classification of disease (ICD)-10 codes, patients with the diagnosis of acute and acute on chronic diastolic heart failure were enrolled in the study. They were further stratified based on the presence of amyloidosis. The primary outcome was to measure in-hospital mortality, while secondary outcomes included development of acute kidney injury (AKI), Acute respiratory failure (ARF), shock and arrhythmias.
Results
Out of the 915,694 patients with Acute Decompensated diastolic heart failure, about 2270 had amyloidosis as secondary diagnosis. 6.1% of ADHF and amyloidosis died in hospital, compared to 4.2% in those without amyloidosis (aOR=1.35 CI=0.89–2.05, p=0.197). On multivariate analysis, patients with Amyloidosis had increased odds of developing AKI (aOR=1.40 CI 1.13–1.72, p=0.001), Cardiogenic shock (aOR=2.67 CI 1.56–4.55, p<0.001) and arrhythmias (aOR=1.34, CI 1.10–1.64, p=0.004). The incidence of ARF was however lower in patients without amyloidosis compared to those with it (aOR=0.60, CI 0.47–0.75, p<0.001).
Conclusion
Amyloidosis is one of the underappreciated and underdiagnosed causes of heart failure. Our study shows an increased risk of complications in acute decompensated heart failure with the presence of amyloidosis. Thus, physicians must be aware of this clinical entity for early diagnosis as patients with advanced disease are likely to have poor prognoses.

Abstract
Abstract
Background
Heart failure (HF) constitutes a huge public health burden today with acute respiratory infections being among the main precipitating causes for hospitalization. On the other hand, HF is a known risk factor for pneumonia which is the most common cause of adult hospital admissions in the United States.
Objective
To examine the effect of HF on the in-hospital outcomes of pneumonia
Methods
The National Inpatient Sample (NIS) database, 2016–2018, was queried for inpatient principal diagnosis of all-cause pneumonia, and the study group was stratified into those with and without HF as a secondary diagnosis, using International Classification of Diseases-10 (ICD-10) codes. Multivariate logistic and linear regression analyses were used to adjust for confounding. Stata 16 software was used for data analysis.
Results
1,929,598 adults were hospitalized with the primary diagnosis of pneumonia, of which 499,740 (25.9%) had HF. The incidence of mortality was 4.2% (n=20,785) in those with HF compared to 2.0% (n=28,365) in those without HF. The adjusted odds ratio (aOR) of inpatient mortality for pneumonia patients with HF compared to those without HF was 1.35 (95% CI, 1.29–1.42; p<0.001) when adjusted for patient demographics, comorbidities, and hospital characteristics. The adjusted hospital length of stay (LOS) in pneumonia patients with HF as compared to those without HF (mean difference= +1.40 days, p<0.001) was significantly longer. Complications such as arrhythmias (aOR=3.18; 95% CI, 3.12–3.25; p<0.001), acute hypoxic respiratory failure (aOR=1.26; 95% CI, 1.24–1.29; p<0.001), acute kidney injury (aOR=1.34; 95% CI, 1.31–1.37; p<0.001), septic shock (aOR=1.60; 95% CI, 1.41–1.81; p<0.001), cardiogenic shock (aOR=7.40; 95% CI, 5.65–9.65; p<0.001) and cardiac arrest (aOR=1.91; 95% CI, 1.71–2.14; p<0.001) were more common in pneumonia patients with HF than those without HF.
Conclusion
In patients hospitalized for pneumonia, HF is associated with increased odds of inpatient mortality and longer LOS. Complications such as arrhythmias, acute hypoxic respiratory failure, acute kidney injury, septic shock, cardiogenic shock and cardiac arrest occur more frequently in pneumonia patients with HF.
