Abstract

Background
Systemic sclerosis (SSc) is a multisystem autoimmune disease affecting skin and multiple organs. Although immunopathological evidence supports direct arterial involvement leading to tissue ischemia in SSc, factors associated with arterial involvement are not precisely determined due to the rarity of SSc. In this study, we aimed to investigate aortic stiffness and endothelial functions in patients with SSc.

Methods
Patients under treatment of our Rheumatology department and healthy controls have been included in our study. Aortic stiffness was examined by pulse wave velocity (PWV) exam and endothelial functions were assessed by flow mediated dilation (FMD). Individuals with known atherosclerotic risk factors were excluded from our study. A thorough biochemical examination of all individuals and immunologic markers of patients with SSc was completed. All of the organ involvements in patients with SSc were noted and modified Rodnan skin score (MRSS) was calculated.

Results
A total of 61 patients and 75 healthy controls were included in our study. Brachial-ankle PWV values were significantly higher (6.89±0.93 vs 6.49±0.22 m/sec; p:0.001) and brachial FMD values were significantly lower (16.7±6.7 % vs 18.7±3.8 %; p: 0.03) in patients with SSc. We have also grouped individuals according to severe FMD impairment (FMD &lt; 10%). None of the healthy controls had severe impairment whereas 15 patients with SSc had FMD values lower than 10%. Higher anti-smooth muscle (Sm) antibody positiveness (40 % vs 15.4 %), lower complement 4 levels (23.6±16.7 vs 31.1±11.1 mg/dL), higher plasma iron values (70.3±43.6 vs 31.4±45.2 mcg/dL) and lower MRSS values (11.4±4.8 vs 20.7±10.9) were observed in SSc patients with severe FMD impairment. When we have put these variables in multivariate logistic regression analysis (backward elimination model), we have found an independent association of complement 4 levels (OR: 0.03, [95 % CI: 0.01-0.491], p:0.04) and MRSS values (OR: 0.853, [95 % CI: 0.761-0.955], p:0.006) with significant FMD impairment in patients with SSc.

Conclusion
Arterial stiffness is significantly increased and endothelial functions, as assessed by FMD is significantly decreased in patients with SSc, when compared to healthy controls. Lower complement 4 levels and lower modified Rodnan skin scores seem to be independently associated with significant severe FMD impairment. Although our study included a remarkable amount of patients with SSc, an infrequent autoimmune disease, number of patients included in our study is not adequate to make more precise comments. Further prospective studies with higher amount of patients are required for certain results.

Abstract

Background
Behçet's syndrome (BS) is a complex multisystemic vasculitis that affects vessels of all sizes and kinds, with a high tendency towards thrombosis. Arterial disease is rare and manifests primarily in the form of pulmonary artery aneurysms (PAA), but also of pulmonary artery thrombosis (PAT) in 1/3 of the cases.

Purpose
Our work aims to depict the profile and outcomes of BS patients presenting with PAT.

Methods
This retrospective, descriptive, and monocentric study was conducted between 2000 and 2022, among 531 adult patients diagnosed with BS (ISG and/or ICBD criteria). All cases of documented PAT were included.

Results
16 cases of PAT were recorded (3%). The mean age of the patients was 34 ± 6 years (19-58), and the sex ratio (M/F) was 4.7:1. Cardiovascular risk factors were mainly active smoking (12%) and high blood pressure (6%). PAT was the revealing manifestation of BS (30%), or occurred after a median of 4.5 years following BS onset. Patients were mostly asymptomatic (69%), or presented with dyspnea (35%), hemoptysis (31%), and thoracic pain (25%). On chest CTA, PAT was often bilateral (78%) and proximal (46%). PAA were frequently observed (25%), being consistently bilateral, multiple, proximal and distal at the same time. Deep venous thrombosis was found in the lower extremities (19%), superior vena cava (27%), and inferior vena cava (6%). Cardiac involvement was also commonly associated (40%), mostly consisting of right intracardiac thrombosis (37%). Concomitant extracardiovascular involvements included mucocutaneous (87%), ocular (26%), articular (25%), and digestive (6%) lesions. Inflammatory parameters were raised in most patients (80%). Hemostasis parameters were within normal ranges and screening for inherited and acquired thrombophilia was negative in all cases. Patients were treated with colchicine (97%), glucocorticoids (93%), cyclophosphamide (47%), azathioprine (47%), and a TNF-a-inhibitor (6%). Curative anticoagulation with low-molecular-weight heparin followed by oral antivitamin K was often prescribed (60%). No surgery or endovascular procedure was performed. Relapse and death were recorded in respectively 15% and 26% of the cases.

Conclusion
In contrast to common thrombotic diseases, PAT in BS is attributed to vasculitis rather than hypercoagulability, resulting in distinct clinical features. The diagnosis should be promptly considered in young men who present with concurrent thrombotic lesions and PAA. Early and appropriate management is imperative to enhance patient outcomes.Left proximal PAT in a BS patient

Abstract

Background
Psoriasis is a complex autoinflammatory disease that has been associated with atherosclerosis, higher risks of cardiovascular diseases, and electrocardiographic changes. Whether these risk factors lead to higher risks of out-of-hospital cardiac arrest (OHCA) is undetermined.

Purpose
To investigate whether psoriasis is associated with OHCA.

Method
Using the nationwide Danish Cardiac Arrest Registry, we identified adult (≥18 years) OHCA patients of presumed cardiac cause with and without psoriasis between June 1st 2001 and December 31st 2019. The association of cardiac arrest was estimated using time-varying Cox regression fitted with a nested case-control design where we matched up to five controls per case on age, sex and year of OHCA and 4 comorbidities: ischemic heart disease, congestive heart failure, cardiovascular risk factors, and major extra cardiac organ disease. In subgroup analyses, the main analysis was repeated in patients with severe psoriasis (presence of inpatient hospital contact during the previous year) as compared to mild psoriasis.

Results
We included 43,967 OHCA cases and matched with 219,772 controls from the general population. The median age was 72 years, 68% were male and 26% had ischemic heart disease, 21% had congestive heart failure, 57% had cardiovascular risk factors, and 33% had extra cardiac organ disease (Table 1). We identified 1,145 (2.6%) cases and 4,971 (2.3%) controls who had psoriasis. Compared with cardiac arrest cases without psoriasis, cases with psoriasis had similar age and sex distribution, prevalence of ischemic heart disease, and congestive heart failure, but a higher prevalence of cardiovascular risk factors, major extra cardiac organ disease and Charlson score distribution. Psoriasis was significantly associated with higher hazard ratios of OHCA: HR 1.16 [95% confidence interval: 1.08 - 1.23] (Figure 1). Compared to no psoriasis, having severe psoriasis was significantly associated with higher hazard of OHCA: HR 1.98 [95% confidence interval: 1.10 - 3.61], while mild psoriasis was not (Figure 1).

Conclusion
In this nationwide nested case-control study, psoriasis was significantly associated with increased hazard of out-of-hospital cardiac arrest. Furthermore, the association was only significant with severe psoriasis compared to those without psoriasis, while mild psoriasis was not. This study highlights the importance of examining cardiovascular risk factors and prioritizing prevention of cardiovascular disease in patients with psoriasis.Figure 1Table 1

Published: October 2024

Abstract

Introduction
Patients (pts) with osteoporosis (OP) have an increased 10-year cardiovascular death risk. Low bone mineral density (BMD) observed in OP may be associated with arrhythmic presentation of cardiovascular diseases (CVD). Few studies assessed the relationship between OP and arrhythmia.

Aim
Arrhythmias assessment in pts with OP.

Methods
A total of 103 postmenopausal female pts (mean age 69 +/- 7), consulted by endocrinologist, were divided into 2 groups according to BMD (assessed by dual energy X-ray absorptiometry). BMD measurements, expressed as T-score (T-sc), were taken from the femoral neck (T-sc Neck), entire total hip (T-sc TH) and/or spine (T-sc L2-L4, L1-L4). Arrhythmia was evaluated using 24-hour Holter-ECG monitoring (HM). Major osteoporotic and total hip fracture risks (MOFR and THFR, respectively) were assessed by the FRAX scale. We compared 51 pts with OP (T-sc ≤ -2.5), with 52 matched controls without OP, including 44 pts with osteopenia (T-sc &gt; -2.5). There were no significant differences between the groups regarding the history of stroke, myocardial infarction, coronary artery disease or arterial hypertension. Exclusion criteria included heart failure NYHA &gt;II and/or LVEF &lt;36%, acute coronary syndrome within the last 6 months, severe valvular disease, cardiac implantable electronic device.

Results
There was a trend towards a greater number of supraventricular and ventricular arrhythmias in the OP group compared to the controls. Arrhythmic burden was significantly correlated with BMD measures: correlations were observed between 24-hour ventricular ectopic beats (VEB) count with T-sc Neck (r=-0.20, p=0.04), with T-sc TH (r=-0.22, p=0.03). The number of supraventricular ectopic beats (SVEB) in HM was also correlated with BMD parameters: T-sc Neck (r=-0.21, p=0.03), T-sc TH (r=-0.23, p=0.02). Multivariate analysis (linear regression model) revealed that age and T-sc TH were independently related with ectopy: age (0.07; CI: 0.01 - 0.13, p=0.03) and T-sc TH (-0.58; CI: -1.07 - -0.08, p=0.02) were predictors for VEB, and SVEB were related to age (0.07; CI: 0.03 - 0.12, p&lt;0.01) and, with borderline significance with T-sc TH (-0.34; CI: -0.699 - 0.012, p=0.058). Ectopic beats count was also positively correlated with osteoporotic fracture risk: VEB with THFR (r=0.206, p=0.04) and SVEB with MOFR (r=0.21, p=0.04).

Conclusions
The study showed an increased arrhythmia burden as detected in HM in pts with OP. Beside the T-sc TH, age was identified as an independent factor of increased SVEB / VEB. The main significant negative correlations were observed between the number of VEB / SVEB and BMD in femur (T-sc Neck, T-sc TH). Ectopic beats count was also positively correlated with osteoporotic fracture risk: VEB with THFR and SVEB with MOFR.

Published: October 2024

Abstract

Introduction
Heart failure (HF) is one of the leading causes of death from cardiovascular disease. Persistent atrial fibrillation (PAF) is associated with a worse prognosis in HF. However, little is known about the influence of AF on mortality in women and men with heart failure with preserved (HFpEF ≥50%), mildly reduced (HFmrEF 41% to 49%), and reduced ejection fraction (HFrEF ≤40%).

Purpose
to analyze the characteristics and influence of PAF on the prognosis of different HF phenotypes.

Methods
From February 2017 to September 2020, we analyzed hospitalizations, emergency admissions, and mortality of different HF phenotypes with and without PAF. Baseline data included clinical features and echocardiographic findings. Statistical analyses were performed using the Kaplan-Meier (K-M) and Cox proportional hazards methods to analyze mortality rates.

Results
We studied 11,543 patients, with a mean of 64.1±14.0 years: 55.1% male, 42% with HFrEF, 12.8% with HFmrEF, and 45.1% with HFpEF. PAF was associated with higher mean age (67.6±14.3 vs. 62.8±13.4 years, p&lt;0.001) and more prevalent in men (21% vs. 19%; p=0.019) and in patients with valvular and Chagas etiologies, chronic kidney disease (CKD), stroke, and anemia. The prevalence of PAF in women and men was, respectively, 12.4% vs. 18.3% (p&lt;0.001) in HFrEF, 18.1% vs. 22.2% (p=0.029) in HFmrEF, and 23.3% vs. 23.9 (p=NS) in HFpEF. The overall mortality was 21.6%, with mortality being 2.4 times higher in patients with PAF (40.9% vs. 16.7%, p&lt;0.001) compared to sinus rhythm but similar in women and men with PAF (39.5% vs. 41.9%; p=NS), respectively. The hospitalization (30.3% vs 19.4%, p&lt;0.001) and emergency admissions (38.4% vs 25.7%, p&lt;0.001) were higher in patients with AF. Cumulative mortality was higher in patients with PAF in all HF phenotypes: HFrEF (36.6%), HFmrEF (16.8%), HFpEF (46.6%; p&lt;0.001). Men had higher cumulative mortality in HFrEF (18.3% vs. 12.4%; p&lt;0.001) and in HFmrEF (22.2% vs. 18.09%; p=0.029), but not for HFpEF (23.9% vs. 23.3%; p=NS). In the multivariate analysis, adjusted for age, sex, previous myocardial infarction and stroke, diabetes, CKD, PAF, Cardiac surgery, and electronic device implantation, PAF was an independent predictor of death in all HF phenotypes: HFrEF [HR=1.78(95%CI:1.57-2.02); p&lt;0.001], HFmrEF [HR=2.14(95%CI:1.74-2.65); p&lt;0.001], HFpEF [HR=2.08(95%CI:1.82-2.37); p&lt;0.001].

Conclusion
PAF is a frequent comorbidity in HF and is associated with a worse prognosis in all HF phenotypes. Women with PAF had a better prognosis than men with AF in HFrEF and HFmrEF. Sex-specific strategies to maintain sinus rhythm in HF patients on the overall risk of death are needed.

Abstract

Background
There are sex differences in the extent, severity, and outcomes of coronary artery disease.

Purpose
To assess the influence of sex on coronary atherosclerotic plaque activity measured using coronary 18F-sodium fluoride (18F-NaF) positron emission tomography (PET), and to determine whether 18F-NaF PET has prognostic value in both women and men.

Methods
In a post-hoc analysis of observational cohort studies of patients with coronary atherosclerosis who had undergone 18F-NaF PET CT angiography, we compared the coronary microcalcification activity (CMA) in women and men.

Results
Baseline 18F-NaF PET CT angiography was available in 999 participants (151 (15%) women) with 4282 patient-years of follow-up. Compared to men, women had lower coronary calcium scores (116 [interquartile range, 27-434] versus 205 [51-571] Agatston units; p=0.002) and CMA values (0.0 [0.0-1.12] versus 0.53 [0.0-2.54], p=0.01). Following matching for plaque burden by coronary calcium scores and clinical comorbidities, there was no sex-related difference in CMA values (0.0 [0.0-1.12] versus 0.0 [0.0-1.23], p=0.21) and similar proportions of women and men had no 18F-NaF uptake (53.0% (n=80) and 48.3% (n=73); p=0.42), or CMA values &gt;1.56 (21.8% (n=33) and 21.8% (n=33); p=1.00). Over a median follow-up of 4.5 [4.0-6.0] years, myocardial infarction occurred in 6.6% of women (n=10) and 7.8% of men (n=66). Coronary microcalcification activity greater than 0 was associated with a similarly increased risk of myocardial infarction in both women (HR: 3.83; 95% CI:1.10-18.49; p=0.04) and men (HR: 5.29; 95% CI:2.28-12.28; p&lt;0.001).

Conclusions
Although men present with more coronary atherosclerotic plaque than women, increased plaque activity is a strong predictor of future myocardial infarction regardless of sex.Sex differences in CAD activityCase examples

Abstract

Background
Angina in the absence of obstructive coronary artery disease (CAD) is a growing cause of morbidity and mortality, exceeding the economic burden of CAD. Roughly 50-70% of patients undergoing invasive angiography for anginal symptoms have non-obstructive CAD. Within this category, there are distinct sub-populations including patients with angina without evidence of ischemia on prior stress testing (ANOCA), evidence of ischemia on stress testing (INOCA), or history of obstructive CAD with prior revascularization (ANOCA-HxCAD). Coronary microvascular dysfunction (CMD) and/or epicardial vasospasm are common causes of angina in the absence of epicardial CAD despite optimal medical therapy. Differences between these groups, in terms of risk factors and diagnoses remain relatively unknown.

Purpose
To compare clinical characteristics, symptoms, and diagnoses between patients with ANOCA, INOCA, and ANOCA-HxCAD.

Methods
In a prospective registry-based cohort study of 306 patients without obstructive CAD (&lt;50% stenosis in epicardial artery) undergoing coronary functional angiography (CFA), we assessed differences in clinical characteristics, symptoms, and CFA diagnoses: (1) endothelial-independent CMD (coronary flow reserve [CFR] &lt;2.5) to adenosine testing, (2) endothelial-dependent CMD (coronary blood flow [CBF]&lt;50% or no change in vessel diameter to 54 mcg intracoronary acetylcholine [ACH]), (3) epicardial vasospasm to 108 mcg intracoronary ACH in 3 groups of patients (ANOCA, INOCA, and ANOCA-HxCAD).

Results
Among the 306 patients undergoing CFA, 89% were female with a median age of 58 years (49, 67). Patients with ANOCA-HxCAD had a significantly higher prevalence of hypertension, diabetes, heart failure with preserved ejection fraction, and experienced worse dyspnea on exertion as measured by University of San Diego Shortness of Breath (UCSD SOB) in comparison to ANOCA or INOCA patients. However, there were no differences between the groups in terms of anginal severity, functional capacity, or quality of life. In terms of CFA diagnoses, vasospasm was more prevalent in ANOCA-HxCAD (p&lt;0.001) and CMD was more prevalent in ANOCA and INOCA patients (p=0.034) (Table 1).

Conclusions
Despite differences in clinical characteristics, patients without obstructive CAD have similar anginal severity, functional capacity, and quality of life regardless of evidence of ischemia on prior stress imaging or history of revascularization. There are differences in CFA diagnoses with higher prevalence of CMD in ANOCA and INOCA patients and higher prevalence of vasospasm in ANOCA-HxCAD patients. Determining the underlying diagnoses changes clinical management; therefore, CFA should be considered in all patients without obstructive CAD.

Abstract

Background
Peripartum cardiomyopathy (PPCM) remains an important cause of cardiac-related maternal morbidity and mortality in previously healthy young women. Data on the long-term clinical course of PPCM are sparse. In this study, we report the long-term outcomes in patients with PPCM.

Methods and Results
Long-term follow-up (median 9.6, min 5, and max 24 years) was available in 72 women with PPCM followed in a cardio-obstetrics clinic. Five-year follow-up data were available for 19 PPCM patients, 10-year follow-up data for 24 PPCM patients, and more than 15 years of follow-up data for 24 PPCM patients. Seven patients were lost to cardiac follow-up but are known to be alive. The mean age at diagnosis was 35 ± 7 years, and 85% were Caucasian. The mean parity was 2.2 ± 1.3, and gravidity was 2.7 ± 1.7. Twin pregnancies were reported in 13% of cases. Pre-eclampsia was present in 25% of the patients and the development of hypertension in the long-term was documented in 18%. The mean LVEF was 34.5 ± 9.9% at diagnosis. One-year LVEF data were available in 72 patients: 54 patients (75%) experienced LV recovery (LVEF≥ 50%). After 1 year, the mean LVEF was 53.4± 8.2%. Among patients remained with LV&lt;50% at one year (n=10) no LV function recovery was reported at long-term follow-up. At a median follow-up of 9.6 years (n=66) mean LVEF was 52.1±10.4%, nine patients had a reduction in LVEF (&lt;50%) function in the long-term follow-up with a mean LVEF of 46.1± 2.1%. Out of 72 PPCM patients, 3 patients developed arrhythmia, in one woman coronary artery disease occurred and 7 underwent pacemaker implantation. Almost half of patients (n=65) remained with long term treatment of b-blockers, 38% received medications for hypertension or heart failure. No cases of myocardial infarctions, cardiovascular death, or heart transplantations were reported. Two women died during follow-up: one with normal LVEF died from breast cancer, and another patient with reduced LVEF and severe diabetes. The cause of her death remained unclear. During follow-up, 30 women had ≥ 1 subsequent pregnancy (SSP), and there was no reduction in their mean LVEF before SSP 57.0 ± 5.4% and at long-term follow-up was 59.6± 1.3% (p=ns).

Conclusion
Our study demonstrates favorable long-term outcomes with high and stable recovery rates with low mortality rates, and no impact of subsequent pregnancies on the clinical course of the condition. Nevertheless, persisting or new diagnosis of hypertension and use of cardiovascular medications were noted in the long term follow up.
