Abstract [en]

AIMS: Non-invasive estimation of left ventricular filling pressure (LVFP) during stress is important for explaining exertional symptoms in patients with heart failure (HF). The aim of this study was to evaluate ability of Doppler echocardiographic measures of elevated LVFP with passive leg lifting (PLL) in patients with suspected HF.

METHODS: Twenty-nine patients with clinical signs of HF who underwent simultaneous Doppler echocardiography and right heart catheterization (RHC) at rest and during PLL were consecutively investigated. Seventeen patients had normal PCWP (≤15 mmHg) at rest and during PLL and 12 with normal PCWP at rest but >15 mmHg with PLL. Conventional echo and 2D strain were used to assess early diastolic blood flow velocity (E), LV strain rate during early diastole (LVSRe), left atrial SR during atrial contraction (LASRa) and myocardial tissue Doppler velocities to assess lateral e' and further calculate E/e' and E/LVSRe and their relationship with PCWP, at rest and during PLL.

RESULTS: Resting LAVI (β = 0·45, P = 0·009) and LASRa (β = -0·51, P = 0·004) were independently related to PCWP during PLL. Also, LASRa (β = -0·77, P<0·001), E/e' (β = 0·40, P = 0·04) and E/LVSRe (β = 0·47, P = 0·021) during PLL correlated with PCWP during PLL. Multiple regression analysis identified E/LVSRe (β = 0·46, P = 0·001) and LASRa (β = -0·58, P = 0·002) during PLL as being independently associated with PCWP during PLL.

CONCLUSION: Left atrial volume and myocardial contraction (LASRa) at rest both predict unstable LV filling pressures measured as raised PCWP when provoked by PLL. Furthermore, LASRa at PLL seems to have the strongest association to PCWP during PLL.

Abstract [en]

Risk prediction of future atherothrombotic cardiovascular events is currently based on conventional risk factor assessment and the use of validated algorithms, such as the Framingham Risk Score, the Pooled Cohort Equations, and the European SCORE Risk Charts. However, the identification of subclinical organ damage has emerged as a potentially more accurate predictor of individual risk. Several imaging modalities have been proposed for identification of preclinical atherosclerosis. Coronary artery calcification scanning performed using cardiac computed tomography and calculation of the Agatston score is the most commonly used technique in clinical practice for detection of subclinical disease, prognostic stratification of asymptomatic individuals and implementation of preventive strategies. Furthermore, conventional echocardiographic examination may offer an assessment of cardiac calcifications at different sites, such as the mitral apparatus (including annulus, leaflets and papillary muscles), aortic valve and ascending aorta, that are associated with the clinical manifestation of atherosclerotic disease and are predictive of future cardiovascular events. The aim of this paper is to summarize available evidence on the clinical use of cardiac calcification, review the pathogenetic mechanisms involved, including similarities with atherosclerosis, and evaluate its potential for risk stratification and prevention of clinical events in the primary prevention setting.

Abstract [en]

Background; Electromechanical (EM) coupling heterogeneity is significant in long QT syndrome (LQTS), particularly in symptomatic patients; EM window (EMW) has been proposed as an indicator of interaction and a better predictor of arrhythmia than QTc. Hypothesis To investigate the dynamic response of EMW to exercise in LQTS and its predictive value of arrhythmia.

Methods: Forty-seven LQTS carriers (45 +/- 15 years, 20 with arrhythmic events), and 35 controls underwent exercise echocardiogram. EMW was measured as the time difference between aortic valve closure on Doppler and the end of QT interval on the superimposed electrocardiogram (ECG). Measurements were obtained at rest, peak exercise (PE) and 4 minutes into recovery.

Results: Patients did not differ in age, gender, heart rate, or left ventricular ejection fraction but had a negative resting EMW compared with controls (-42 +/- 22 vs 17 +/- 5 ms, P < 0.0001). EMW became more negative at PE (-89 +/- 43 vs 16 +/- 7 ms, P = 0.0001) and recovery (-65 +/- 39 vs 16 +/- 6 ms, P = 0.001) in patients, particularly the symptomatic, but remained unchanged in controls. PE EMW was a stronger predictor of arrhythmic events than QTc (AUC:0.765 vs 0.569, P < 0.001). B-blockers did not affect EMW at rest but was less negative at PE (BB: -66 +/- 21 vs no-BB: -113 +/- 25 ms, P < 0.001). LQT1 patients had worse PE EMW negativity than LQT2.

Conclusion: LQTS patients have significantly negative EMW, which worsens with exercise. These changes are more pronounced in patients with documented arrhythmic events and decrease with B-blocker therapy. Thus, EMW assessment during exercise may help improve risk stratification and management of LQTS patients.

Abstract [en]

Extensive coronary calcification without significant stenosis, described as calcific coronary artery disease (CCAD) may cause abnormal myocardial perfusion and hence generalized ischemia. There is a discrepancy in the expression pattern of CCAD compared to the well-known atherosclerotic disease which raises questions about the exact pathophysiology of coronary calcification and whether there is a genetic etiology for it.

In this pilot study we studied 3 candidate genes, ectonucleotide pyrophosphatase/phosphodiesterase (ENPP1), ATP Binding Cassette Subfamily C Member 6 (ABCC6), and 5'-Nucleotidase Ecto (NT5E) involved in pyrophosphate (PPi) and inorganic phosphate (Pi) metabolism, which may predispose to coronary arterial or valvular calcification. We studied 70 patients with calcific cardiac disease; 65 with CCAD (age 43-83 years) and 5 with calcific aortic valve disease (CAVD) (age 76-82 years).

Five DNA variants potentially affecting protein function were found in 6 patients. One variant is a known disease-causing mutation in the ABCC6 gene. Our findings support that disturbances in the PPi and Pi metabolism might influence the development of CCAD and CAVD. However, segregation in the families must first be performed to ascertain any damaging effect of these variants we have found.

We report 4 new genetic variants potentially related to coronary calcification, through the disturbed Pi and PPi metabolism. The search for direct causative genetic variants in coronary artery and aortic valve calcification must be broadened with other genes particularly those involved with Pi and PPi metabolism.

Abstract [en]

Background and Aim: Predictors of exercise capacity in heart failure (HF) with preserved ejection fraction (HFpEF) remain of difficult determination. The aim of this study was to identify predictors of exercise capacity in a group of patients with HFpEF and right ventricle (RV) dysfunction

Methods: In 143 consecutive patients with HFpEF (age 62 ± 9 years, LV EF ≥45) and 41 controls, a complete echocardiographic study was performed. In addition to conventional measurements, LA compliance was calculated using the formula: [LAV max − LAV min/LAV min × 100]. Exercise capacity was assessed using the six‐minute walking test (6‐MWT). Tricuspid annular plane systolic excursion (TAPSE) < 1.7 cm was utilized to categorize patients with RV dysfunction (n = 40) from those with maintained RV function (n = 103).

Results: Patients with RV dysfunction were older (= 0.002), had higher NYHA class (= 0.001), higher LV mass index (= 0.01), reduced septal and lateral MAPSE (all < 0.001), enlarged LA (= 0.001) impaired LA compliance index (< 0.001) and exhibited a more compromised 6‐MWT (= 0.001). LA compliance index correlated more closely with 6‐MWT (= 0.51, < 0.001) compared with the other LA indices (AP diameter, transverse diameter and volume indexed; = −0.30, = −0.35 and = −0.38, respectively). In multivariate analysis, LA compliance index <60% was 88% sensitive and 61% specific (AUC 0.80, CI = 0.67–0.92 = 0.001) in predicting exercise capacity.

Conclusion: An impairment in LA compliance was profound in patients with HFpEF and RV dysfunction and seems to be most powerful independent predictor of limited exercise capacity.

Abstract [en]

Different cut-offs have been proposed for left atrial (LA) size. Furthermore, conflicting results have been reported about the influence of age on LA size and data on the impact of age on LA myocardial function are scanty. The aim of this study was to derive references values for LA size and function in healthy subjects and to evaluate the impact of age. We conducted a systematic literature search of MEDLINE database. We included only studies evaluating healthy subjects, with age ranged between 18 and 80years. Parameters were compared among four age groups, <30, 30-45, >45-60, >60years. Three hundred twenty-six studies met the inclusion criteria and the final population consisted of 62,821 subjects. LA volume index (LAVi) did not differ among different age groups (p=0.21). The normal upper limit of LAVi was 24mL/m(2). LA reservoir function, measured by strain, did not differ among age groups (38 +/- 3%, 32-43%; p=0.74). Left ventricular (LV) size and function were not different among groups, except LV mass index. A decrease in E/A ratio and an increase in E/e ratio were found with advancing age (p<0.0001 and p=0.001, respectively). In healthy subjects the normal upper limit of LAVi was lower than that recommended and is not influenced by advancing age. Furthermore, also LA function measured by strain was not affected by age. The current reference values of LAVi should be used with caution when applied to healthy subjects.
