Introduction: Right ventricular dysfunction (RVD) is an indicator of poor prognosis in normotensive patients with acute pulmonary embolism (APE). The aim of this study was to compare right ventricular (RV)/left ventricular (LV) ratio measured by echocardiography and multidetector computed...

Background:Patients with intermediate-risk acute pulmonary embolism (APE) are a heterogeneous group with an early mortality rate of 2–15%. The tricuspid annulus plane systolic excursion (TAPSE) and tricuspid regurgitation peak gradient (TRPG) can be used for risk stratification, so we analyzed the prognostic value of a new echo parameter (TRPG/TAPSE) for prediction of APE-related 30-day death or need for rescue thrombolysis in initially normotensive APE patients.Methods and Results:The study group consists of 400 non-high-risk APE patients (191 men, age: 63.1±18.9 years) who had undergone echocardiography within the first 24 h of admission. The TRPG/TAPSE parameter was calculated. The clinical endpoint (CE) was a combination of 30-day APE-related death and/or rescue thrombolysis. The CE occurred in 8 (2%) patients. All patients with TAPSE ≥20 mm (n=193, 48.2%) had a good prognosis. Among 206 patients with TAPSE 4.5 were 0.2 and 0.98, respectively. The CE was significantly more frequent in 19 (9.2%) patients with TRPG/TAPSE >4.5 than in 188 (90.8%) with TRPG/TAPSE ≤4.5 (4 (21.1%) vs. 4 (2.1%), P=0.0005). Among normotensive APE patients with TAPSE 4.5 was associated with 21.1% risk of APE-related death or rescue thrombolysis.Conclusions:TRPG/TAPSE, a novel echocardiographic parameter, may be useful for stepwise echocardiographic risk stratification in normotensive patients with APE, and it identifies patients with a poor prognosis.

Bullous pemphigoid (BP) is the most common autoimmune bullous disease associated with higher mortality and coexisting comorbidities. The strongest relationship has been reported with neurological diseases (NDs) but the particular type of ND differed depending on the study. There are some doubts on the prevalence of other comorbidities. The aim of this study was to compare the incidence of various comorbidities in a cohort of BP patients with controls. A cohort of 218 patients (137 females, 81 males, aged 76.2 ±11.6 years) with newly diagnosed BP who were hospitalized at a specialized center in Poland in the years 2000-2014 was included in this retrospective study. The controls consisted of 168 sexand age-matched individuals. Univariate and multivariate logistic regression analyses were performed to assess the association between the groups studied. At least 1 ND was present in 33.5% of BP patients vs 11.3% of controls. A strong association between the incidence of NDs and BP was found (OR = 3.76; 95% CI = 2.13-6.65; p < 0.001), especially for dementia (20.6% vs 2.9%, OR = 7.89; 95% CI = 2.99-20.85; p < 0.001). Surprisingly, BP patients with ND were older than the BP patients without ND (79.2 vs 74.7 years), and similarly for dementia (81.08 vs 74.90 years). The same was observed in comparison with controls. Arterial hypertension, among other comorbidities, was a strong independent factor associated with BP (OR = 2.17; 95% CI = 1.35-3.49; p < 0.001). Malignancies were observed more frequently in BP patients than in controls (12.8% vs 9%) but such association was significant in univariate analysis only. Neurological diseases, particularly dementia, had a significant association with BP. A strong relationship with arterial hypertension and weak relationship with malignancies were noted. Thus, for appropriate medical care, patients with BP need accurate screening for dementia and control of comorbidities with interdisciplinary management.

Objective. To assess the heart rate turbulence (HRT) in patients with SSc as a method of assessment for cardiac autonomic nervous function. Methods. We prospectively studied 68 consecutive patients with SSc before inclusion in the study. After a detailed clinical evaluation, including echocardiography, 45 subjects [aged 54.6 (14.7) years; 40 women] underwent 24-h Holter monitoring for HRT and time- and frequency-domain heart rate variability (HRV) assessment. Results were compared with those in 30 age- and sex-matched healthy controls. Results. As compared with controls, HRT was impaired in SSc patients: the median turbulence onset (TO) was higher (P = 0.0001) and the median turbulence slope (TS) was lower (P = 0.0003). Abnormal HRT (TO ⩾0.0% and/or TS ⩽2.5 ms/RR) was found in 42% of SSc patients. Moreover, SSc duration correlated negatively with values of TS (r = −0.3; P = 0.045). HRT did not differ between diffuse and limited SSc groups. All estimated time- and the majority of frequency-domain values of HRV parameters in SSc were significantly lower than in controls. Significant correlations were also demonstrated between HRT and HRV parameters. Conclusions. HRT, like HRV assessment, indicates a frequent impairment of the cardiac autonomic nervous system in SSc patients, irrespective of the SSc type.

Heart and pulmonary involvement is a leading cause of systemic sclerosis (SSc)-related deaths. The aim of our study was to assess if biochemical markers of right ventricular (RV) overload, endothelial function and collagen metabolism can predict RV dysfunction assessed by Doppler echocardiography in SSc patients. We prospectively studied 111 consecutive patients (101 F, 10 M, age 54.2 ± 13.8 years) with diagnosed SSc (mean disease duration 9.4 ± 11.4 years) and a group of 21 age-matched subjects (18 F, 3 M, age 49.3 + 10.5 years). We performed transthoracic echocardiography (Phillips iE 33) and measured serum endothelin-1 (ET-1), N-terminal pro-brain natriuretic peptide (NT-proBNP), asymmetric dimethylarginine (ADMA), endoglin and human tissue inhibitor of matrix metalloproteinase (TIMP-1) concentration. Median serum NT-proBNP level in SSc patients was 133.5 (range 21.86-17,670 pg/ml) and was significantly higher than in controls (p = 0.0002). Moreover, the median serum ET-1 level of 1.49 (range 0.26-8.75 pg/ml) was higher in SSc patients (p = 0.002). However, no significant differences in ADMA, TIMP-1 and endoglin serum concentration between SSc patients and controls were observed. Serum NT-proBNP concentration correlated positively with echocardiographic signs of RV overload: tricuspid regurgitation pressure gradient (r = 0.38, p = 0.0004) and RV Tei index (r = 0.25, p = 0.01). ET-1 serum level correlated negatively with tricuspid annular plane systolic excursion (r = -0.4, p = 0.01) and positively with inferior vena cava diameter measured at expiration (r = 0.38, p = 0.0002). The echocardiographic signs of RV overload were significantly more pronounced in the highest NT-proBNP tertile (>195 pg/ml) group than in the lowest one (<88 pg/ml). Serum ET-1 and NT-proBNP, but not endoglin, ADMA and TIMP-1 levels correlating with the echocardiographic parameters of RV overload, can be considered as noninvasive indicators of RV dysfunction in SSc patients.
