calcifications in this phantom. The protocol should be extensively validated before clinical use, but it could potentially improve clinical interscanner/interinstitutional reproducibility and enable more consistent risk assessment and treatment strategies.

On state-of-the-art CT systems of 4 different vendors, a 25% reduced dose, thin-slice calcium scoring protocol led to improved intrascanner and interscanner reproducibility and increased detectability of small and low-density calcifications in this phantom. The protocol should be extensively validated before clinical use, but it could potentially improve clinical interscanner/interinstitutional reproducibility and enable more consistent risk assessment and treatment strategies.

Preeclampsia has an increased risk of cardiovascular events later in life. In this retrospective study, we evaluated echocardiographic aspects in women with history of preeclampsia or preeclampsia-related complications in their previous pregnancies.

Consecutive women receiving echocardiography during daily clinical echolab activity were studied using complete echocardiographic examination data and anamnestic data collection of hypertension, diabetes, dyslipidemia, and rheumatic diseases. Studied women should have at least one pregnancy in more than the 10 past years, and were subdivided into two groups according to the history of complicated or physiological pregnancy. Complicated pregnancies were defined by preeclampsia or preeclampsia-related complication, such as preterm delivery or small-for-gestational age newborn. Echocardiographic parameters and prevalence of hypertension, diabetes, dyslipidemia, and rheumatic disease were compared between the two groups of studied women.

From March 2016 to May 2pidalic 12.64 ± 2.377 vs. 13.32 ± 2.548 cm/s; P = 0.003).

Patients with previous preeclampsia present an increased risk of hypertension, diabetes, and rheumatic diseases, suggesting that these women could share a specific predisposition to a high-risk profile. Furthermore, they show a higher prevalence of classically considered echocardiographic hypertensive-derived cardiac damage, suggesting structural and functional left ventricular modifications as subclinical aspects of long-term worse cardiovascular prognosis for these women.

In patients with chronic heart failure, QRS duration is a consistent predictor of poor outcomes. It has been suggested that for indicated patients, cardiac resynchronization therapy (CRT) could come sooner in the treatment algorithm, perhaps in parallel with the attainment of optimal guideline-directed medical therapy (GDMT). We aimed to investigate differences in left ventricular (LV) remodelling in those with narrow QRS (NQRS) compared with wide QRS (WQRS) in the absence of CRT, whether an early CRT strategy resulted in unnecessary implants and the effect of early CRT on outcomes.

Our cohort consisted of 214 consecutive patients with LV ejection fraction (LVEF) of 35% or less who underwent repeat echocardiography 1 year after enrolment. Of these, 116 patients had NQRS, and 98 had WQRS of whom 40 received CRT within 1 year and 58 did not.

In the absence of CRT, patients with WQRS had less LV reverse remodelling compared with those with NQRS, with differences in ΔLVEF (+2 vs. +9%, P < 0.001) ΔLV end-diastolic diameter (-1 vs. -2 mm, P = 0.095), ΔLV end-systolic diameter (-2 vs. -4.5 mm, P = 0.038), LV end-systolic volume (-12.6 vs. -25.0 ml, P = 0.054) and LV end-diastolic volume (-7.3 vs. -12.2 ml, P = 0.071). LVEF was more likely to improve by at least 10% if patients had NQRS or received CRT (P = 0.08). Thirteen (24%) patients with WQRS achieved an LVEF greater than 35% in the absence of CRT; however, none achieved greater than 50%.

A strictly linear approach to heart failure therapy might lead to delays to optimal treatment in those patients with the most to gain from CRT and the least to gain from GDMT.

Currently, there are few available data regarding a possible role for subclinical atherosclerosis as a risk factor for mortality in Coronavirus Disease 19 (COVID-19) patients. We used coronary artery calcium (CAC) score derived from chest computed tomography (CT) scan to assess the in-hospital prognostic role of CAC in patients affected by COVID-19 pneumonia.

Electronic medical records of patients with confirmed diagnosis of COVID-19 were retrospectively reviewed. Patients with known coronary artery disease (CAD) were excluded. A CAC score was calculated for each patient and was used to categorize them into one of four groups 0, 1-299, 300-999 and at least 1000. The primary endpoint was in-hospital mortality for any cause.

The final population consisted of 282 patients. Fifty-seven patients (20%) died over a follow-up time of 40 days. The presence of CAC was detected in 144 patients (51%). Higher CAC score values were observed in nonsurvivors [median 87, interquartile range (IQR) 0.0-836] compared with linical variables in predicting in-hospital mortality. Only patients with the highest atherosclerotic burden (CAC ≥1000) could represent a high-risk population, similarly to patients with known CAD.

The impact of glucose-6-phosphate dehydrogenase (G6PD) deficiency on coronary atherosclerosis has not been clearly investigated so far. check details We aimed to assess the effects of G6PD deficiency on the extent and complexity of coronary atherosclerosis in a large unselected cohort of consecutive patients with acute coronary syndromes (ACS).

We studied 623 consecutive patients presenting with ACS and undergoing coronary angiography and percutaneous coronary intervention (PCI). G6PD activity was quantitatively measured in all individuals using a biochemical assay based on the G6PD/6GPD ratio in erythrocytes. Individuals were defined as deficient when the ratio was less than 0.80. The severity and complexity of coronary atherosclerosis were assessed by SYNTAX score at baseline angiography.

Fifty-six patients (9%) showed G6PD deficiency. Severe (i.e. enzymatic activity < 0.10) G6PD deficiency was detected in 33 (5.3%) individuals, mainly of male sex (n = 32). Overall, the cardiovascular risk profile was similar between patients with G6PD deficiency and controls.
