Abstract [en]

Objective. Atherosclerosis is a systemic inflammatory disease that can affect more than one arterial bed simultaneously. The aim of this study was to determine the relationship between ultrasound markers of atherosclerosis and multiple arterial disease. Design. We have included 87 currently asymptomatic carotid disease patients (mean age 69 +/- 6 year, 34% females) in this study. Intima media thickness (IMT) and intima media-grey scale median (IM-GSM) were measured in the common carotid artery (CCA), and correlated with previous and/or current atherosclerotic vascular disease in the coronary, carotid and lower extremities. Patients were divided into three groups: (1) asymptomatic, (2) previous symptoms in one arterial territory and (3) previous symptoms in multiple arterial territories. Results. Patients with previous disease in the coronary arteries had higher IMT (p=.034) and lower IM-GSM (p<.001), and those with prior stroke had lower IM-GSM (p=.007). Neither IMT nor IM-GSM was different between patients with and without previous lower extremity vascular disease. IM-GSM was significantly different between groups, it decreased significantly with increasing number of arterial territories affected (37.7 +/- 15.4 vs. 29.3 +/- 16.4 vs. 20.7 +/- 12.9) p<.001, for asymptomatic, symptoms in one and in multiple arterial systems, respectively. Conventional IMT was not significantly different between groups p=.49. Conclusion. Carotid IMT was higher and IM-GSM lower in patients with symptomatic nearby arterial territories but not in those with peripheral disease. In contrast to conventional IMT, IM-GSM can differentiate between numbers of arterial territories affected by atherosclerosis, suggesting that it is a better surrogate for monitoring multiple arterial territory disease.

Abstract [en]

BACKGROUND: Coronary artery ectasia (CAE) is a rare disorder commonly associated with additional features of atherosclerosis. In the present study, we aimed to examine the systemic immune-inflammatory response that might associate CAE.

METHODS: Plasma samples were obtained from 16 patients with coronary artery ectasia (mean age 64.9 ± 7.3 years, 6 female), 69 patients with coronary artery disease (CAD) and angiographic evidence for atherosclerosis (age 64.5 ± 8.7 years, 41 female), and 140 controls (mean age 58.6 ± 4.1 years, 40 female) with normal coronary arteries. Samples were analyzed at Umeå University Biochemistry Laboratory, Sweden, using the V-PLEX Pro-Inflammatory Panel 1 (human) Kit. Statistically significant differences (p < 0.05) between patient groups and controls were determined using Mann-Whitney U-tests.

RESULTS: The CAE patients had significantly higher plasma levels of INF-γ, TNF-α, IL-1β, and IL-8 (p = 0.007, 0.01, 0.001, and 0.002, respectively), and lower levels of IL-2 and IL-4 (p < 0.001 for both) compared to CAD patients and controls. The plasma levels of IL-10, IL-12p, and IL-13 were not different between the three groups. None of these markers could differentiate between patients with pure (n = 6) and mixed with minimal atherosclerosis (n = 10) CAE.

CONCLUSIONS: These results indicate an enhanced systemic pro-inflammatory response in CAE. The profile of this response indicates activation of macrophages through a pathway and trigger different from those of atherosclerosis immune inflammatory response.

Abstract [en]

Recent European Society of Cardiology and American Heart Association/American College of Cardiology Guidelines did not recommend biomarker-guided therapy in the management of heart failure (HF) patients. Combination of echo- and B-type natriuretic peptide (BNP) may be an alternative approach in guiding ambulatory HF management. Our aim was to determine whether a therapy guided by echo markers of left ventricular filling pressure (LVFP), lung ultrasound (LUS) assessment of B-lines, and BNP improves outcomes of HF patients. Consecutive outpatients with LV ejection fraction (EF) <= 50% have been prospectively enrolled. In Group I (n=224), follow-up was guided by echo and BNP with the goal of achieving E-wave deceleration time (EDT) >= 150 ms, tissue Doppler index E/e' < 13, B-line numbers < 15, and BNP <= 125 pg/ml or decrease > 30%; in Group II (n=293), follow-up was clinically guided, while the remaining 277 patients (Group III) did not receive any dedicated follow-up. At 60 months, survival was 88% in Group I compared to 75% in Group II and 54% in Group III (chi(2) 53.5; p<0.0001). Survival curves exhibited statistically significant differences using Mantel-Cox analysis. The number needed to treat to spare one death was 7.9 (Group I versus Group II) and 3.8 (Group I versus Group III). At multivariate Cox regression analyses, major predictors of all-cause mortality were follow-up E/e' (HR: 1.05; p=0.0038) and BNP > 125 pg/ml or decrease <= 30% (HR: 4.90; p=0.0054), while BNP > 125 pg/ml or decrease <= 30% and B-line numbers >= 15 were associated with the combined end point of death and HF hospitalization. Evidence-based HF treatment guided by serum biomarkers and ultrasound with the goal of reducing elevated BNP and LVFP, and resolving pulmonary congestion was associated with better clinical outcomes and can be valuable in guiding ambulatory HF management.

Abstract [en]

Purpose: We aimed to assess the relationship between mitral regurgitation (MR) severity, symptoms, and left atrial (LA) structure and function, before and after mitral valve repair (MVR).

Methods: Global peak atrial longitudinal strain (PALS) was evaluated in 37 patients with severe symptomatic MR and preserved left ventricular (LV) ejection fraction (60.4% ± 4.6%) before and 3 months after MVR and was compared with values from 30 age- and gender-matched controls.

Results: Before surgery, PALS was worse in patients than in controls and indexed LA volume was greater (P < .0001 for both). After MVR, PALS deteriorated further and LA volume decreased (P = .001 and P = .05, respectively) as did LV ejection fraction, longitudinal strain (P = .05 and P < .001, respectively), and LV mass (P < .0001). Before surgery, LA volume correlated modestly with LV end-diastolic volume (R = 0.51; P = .01); effective regurgitant orifice area (EROA) correlated with PALS (R = −0.69, P < .001) and with LV longitudinal strain (R = 0.54, P = .01), and New York Heart Association class correlated with PALS (R = −0.69, P < .001), EROA (R = 0.69, P < .001), and LA volume (R = 0.51, P = .04). LA volume was the strongest predictor of global PALS reduction (P < .001), whereas global PALS was the main predictor of postoperative atrial fibrillation (AF) (P < .001).

Conclusions: In patients with severe MR, EROA correlate with symptoms and LA PALS, which itself predicts the occurrence of postoperative AF. Strain values were superior to 2D data for the prediction of postoperative AF.

Abstract [en]

Background and aim: QRS amplitude and duration are associated with increased left ventricular (LV) volume, mass and dysfunction. However, the diagnostic concordance between QRS measurements and LV morphology and function, as shown by Doppler echocardiography, is not well established. We investigated the relationships of QRS duration and amplitude with echocardiographic measurements of LV morphology and systolic and diastolic function in normal individuals.

Methods: Individuals without signs or symptoms of coronary artery disease or heart failure, who underwent clinical examination as a part of a cross-sectional survey for the prevalence of coronary risk factors, randomly selected from the population list in Caltanissetta, Italy, were included in the study. QRS duration and amplitude were automatically measured using inbuilt software. LV ejection and filling patterns were studied using Doppler echocardiography.

Results: We studied 184 individuals (96 men and 88 women), mean age 55.9 (11.3). QRS duration increased by 5.4ms for every 100g increase in LV mass, and by 4.6ms for each 10mm increase in LV end-diastolic diameter. The amplitude increased by 0.8mm for every 100g increase in LV mass. There was no relationship with LV dimensions. A nonlinear correlation was found between QRS amplitude and indexes of global dyssynchrony. The time-voltage QRS area correlated with LV mass, dimensions and indexes of dyssynchrony. There was no relationship between QRS measurements and ejection fraction.

Conclusions: QRS prolongation and increase in amplitude are strongly influenced by LV increased mass and volume, as well as by dyssynchrony, independently of ejection fraction.

Abstract [en]

Background: The extent of right ventricular (RV) involvement in transthyretin amyloidosis (ATTR) is unknown.

Objectives: This study sought to establish the degree of RV involvement in ATTR amyloidosis, and compare findings with RV involvement in hypertrophic cardiomyopathy (HCM).

Methods: Forty-two patients with ATTR amyloidosis and echocardiographic evidence of cardiac amyloidosis (cardiac ATTR), 19 ATTR patients with normal left ventricular (LV) wall thickness (non-cardiac ATTR), 25 patients with diagnosed HCM and 30 healthy controls were included in this study. Echocardiographic measurements for conventional parameters, as well as RV global and segmental strain, were recorded.

Results: When comparing RV structure and function between cardiac ATTR amyloidosis and HCM patients, only segmental strain differed between the two groups. In cardiac ATTR amyloidosis, we found an RV apex-to-base strain gradient with highest deformation in the apex. This pattern was reversed in patients with HCM.

Conclusions: RV involvement is common in cardiac ATTR patients. The present study also detected an RV apical sparing pattern in patients with ATTR cardiomyopathy, similar to what has previously been described for the left ventricle in these patients. This pattern was not seen in HCM patients. Further studies are needed to assess the clinical importance of these findings.

Abstract [en]

Background and Aim: Whether aging affects left ventricular (LV) filling and ejection and the LV electric function is not well established. We investigated the effect of normal aging on echocardiographic measurements of LV morphology and function, LV electric function and the relationship between LV electric and mechanical func-tion in asymptomatic individuals.

Methods: As part of a cross-sectional survey for the prevalence of coronary risk fac-tors in the general population in Caltanissetta, Italy, individuals without signs or symptoms of coronary artery disease or heart failure were randomly selected and underwent electrocardiographic and echocardiographic examination. QRS duration and amplitude, PR, QT and QTc intervals, were automatically measured. Echocardiographic examination included the measurement of LV systolic and dias-tolic dimensions, volumes and ejection fraction (EF). From the spectral Doppler flow LV early diastolic (E wave) and atrial systolic (A wave) velocities, isovolumic relaxation time (IVRT) and isovolumic contraction time (IVCT) were measured. Global LV dys-synchrony was assessed using the total isovolumic time (T-IVT) and the Tei index.

Results: Aging reduced LV long-axis function, LV filling time and E wave velocity and prolonged T-IVT, IVRT and Tei index. It did not affect LV dimensions, ejection frac-tion, IVCT or QRS amplitude and duration. QRS duration correlated with LV dimen-sions, wall thickness and left atrial area. QRS amplitude and QTc interval correlated with the markers of LV dyssynchrony T-IVT and Tei index.

Conclusions: Overall, systolic and electric LV function are not affected by age, whereas subendocardial function, diastolic and synchronous function are signifi-cantly influenced.

Abstract [en]

Arterial calcification is commonly seen in atherosclerosis, chronic kidney disease (CKD) and diabetes and has long been considered a natural progression of atherosclerosis. Yet it is a systemic condition, occurring in a wide and diverse range of disease states and no medical treatment for cardiovascular disease has yet found a way to regress it; on the contrary, lipid-lowering therapy may worsen its progression. Although numerous studies have found associations between calcification and biomarkers, none has yet found a unifying mechanism that explains the calcification found in atherosclerosis, CKD or diabetes and many of the biomarkers are equally associated with atheroma development and cardiovascular events. Furthermore, both presence and absence of coronary artery calcification appear predictive of plaque rupture and cardiovascular events, indicating that the association is not causal. This suggests that we are no further forward in understanding the true nature of arterial calcification or its pathogenesis, other than noting that it is 'multifactorial'. This is because most researchers view arterial calcification as a progressive pathological condition which must be treated. Instead, we hypothesise that calcification develops as an immune response to endothelial injury, such as shear stress or oxidative stress in diabetics, and is consequently part of the body's natural defences. This would explain why it has been found to be protective of plaque rupture and why it is unresponsive to lipid-lowering agents. We propose that instead of attempting to treat arterial calcification, we should instead be attempting to prevent or treat all causes of endothelial injury.

Abstract [en]

Background and aims: Patients with coarctation of the aorta (CoA) have increased left ventricular (LV) afterload that has been shown to impact the LV and ascending aortic function. We aimed to examine the effect of coarctation on LV function and aorto-septal angle (AoSA) before and after surgical repair.

Methods: We retrospectively studied 21 patients with surgically repaired CoA at a median age of 9 (2-53) days at three time points: (1) just before intervention, (2) at short-term follow-up, and (3) at medium-term follow-up after intervention. AoSA was measured from the parasternal long axisview, at three time points during the cardiac cycle: (1) end diastole, (2) beginning of systole, and (3) at peak ejection in the descending aorta. In addition to conventional LV structure and function, global longitudinal strain, and strain rate were measured using STE technique and Tomtec soft-ware. Three groups of age matched healthy children served as controls at each time point.

Results: AoSA was significantly wider before intervention, in particular at peak ejection in the descending aorta (1448 6 6.48 vs. 1368 6 4.18; P < .0001), and correlated with CoA pressure gradi-ent. After intervention, AoSA normalized and significantly correlated with the increase of LV cavity function and overall LV deformation parameters.

Conclusions: AoSA is abnormally wide in neonates with CoA and is associated with severity ofobstruction, LV dysfunction and compromised LV global deformation.
