Background Left atrial (LA) enlargement (LAE) is associated to an increased risk of cardiovascular complications, and in particular of atrial fibrillation. The 2018 ESH/ESC Hypertension guidelines suggested the use of LA volume instead of linear dimensions, and for the first time proposed the indexation to height2 (h2) The aim of our study was to assess the prevalence of left atrial dilatation in a large sample of patients undergoing an echocardiogram for cardiovascular risk stratification at an ESH excellence centre in Italy. Design and methods 3872 subjects undergoing a diagnostic work-up for arterial hypertension (known or suspect) were analysed. The mean age was 56±15 years, BMI 26±5 kg/m, 44% normal weight, 39% overweight, 17% obese, 53% males. Left atrial volume was measured by the area-length method using the apical 4-chamber and 2-chamber views. Results The prevalence of left ventricular hypertrophy (LVH) was 11% when indexing for BSA and 12% when indexing for height2.7. LAE was observed in 30% of subjects when indexing for h2 and in 9% when indexing for BSA. In obese or overweight subjects the prevalence of LAE was 38% of subjects when indexing for h2 and in 11% when indexing for BSA. The different prevalence of LAE was particularly evident in extremely obese patients. LAE was very common in patients with LVH: 62% and 26% when indexing for h2 and for BSA, respectively. Interestingly, it was frequent also in patients without LVH, in particular when the indexation for h2 was used (25% as compared to 7% when indexing for BSA). Conclusions In a large sample of subjects undergoing a diagnostic work-up for arterial hypertension LAE was frequently observed, particularly when the new indexation proposed by the 2018 ESH/ESC hypertension guidelines was used. Even in the absence of clear-cut LVH, LAE was observed in one quarter of subjects. The indexation to BSA leads to an under-recognition of LAE, in particular in patients with overweight and/or obesity

A non-invasive approach for the estimation of mechanical efficiency through the calculation of the ratio between stroke work and HR-pressure product has been recently proposed by de Simone et al. This index, which expresses the amount of blood pumped in a single beat in 1 second by the heart, may be easily obtained by echocardiography. The aim of our study was to evaluate the determinants of myocardial mechanoenergetic efficiency index (MEEi), calculated as stroke volume/heart rate and indexed to LV mass (MEEi = MEE/LVM) in a large general population sample in Northern Italy. Design and methods: We evaluated 478 subjects participating in a general population study in Northern Italy (Studio Vobarno). All subjects underwent a physical examination with measurement of clinic blood pressure (BP). In all subjects laboratory examinations, 24 hours blood pressure measurement, echocardiography, and assessment of carotid-femoral pulse wave velocity (PWV) were performed. Results: Subjects had a mean age of 58±10 years, a BMI of 26±4, 44% were males, 69% had arterial hypertension (55% treated). MEEi was lower in males and in patients with increased PWV. MEEi was inversely correlated with age, BMI, waist circumference, clinic and 24 hours BP, glucose, uric acid, triglycerides and directly correlated with HDL. MEEI was also inversely correlated with relative wall thickness (RWT) and PWV. At linear regression multivariate (?) analysis MEEi remained independently related to male gender (β = 0.16, p < 0.001), BMI (β = −0.13, p < 0.005), RWT (β = −0.56, p < 0.001) and PWV (β = −0.10, p < 0.05). Conclusions: In a large sample of general population in Northern Italy myocardial mechanoenergetic efficiency was inversely correlated with arterial stiffness, independently of multiple possible confounders.

Objective:It has been suggested that measurement of “unattended” or “automated oscillatory(AOBP)” blood pressure values may provide advantages over conventional BP measurement and some hypertension guidelines now suggest this approach as the preferred one for measuring office BP. Data on the strengt
