AIM Evidence on systolic dysfunction, as assessed by left ventricular (LV) mechanics, in hypertensive heart disease phenotyped by abnormal LV geometric patterns is still limited. Thus, we performed a systematic meta-analysis of 2D/3D speckle-tracking studies in order to provide an updated comprehensive information on this topic. METHODS The PubMed, OVID-MEDLINE, and Cochrane library databases were analyzed to search for articles published from the inception up to 31 January 2021. Studies were identified by using MeSH terms and crossing the following search items: 'myocardial strain', 'left ventricular mechanics', 'speckle tracking echocardiography', 'systolic dysfunction', 'hypertensive heart disease', 'left ventricular hypertrophy', left ventricular remodeling", 'concentric hypertrophy', 'eccentric hypertrophy'. RESULTS Overall, data of 267 normotensive controls and 712 hypertensive patients (234 normal geometry, 97 LV concentric remodeling, 176 eccentric LVH, and 205 concentric LVH) from eight studies were considered. Pooled ejection fraction was similar in normotensives and in the whole group of hypertensive patients: (SMD 0.037 ± 0.05, confidence interval (CI): 0.14/0.07, P = 0.51) as well as in hypertensive subgroups. LVMI, and E/e' gradually increased from hypertensive patients with normal geometry and concentric remodeling, to patients with eccentric and concentric LVH. LV global longitudinal strain (GLS) was lower in all hypertensive groups compared with normotensive controls, in particular, in the eccentric (SMD 1.14 ± 0.22, CI: 0.69/1.59, P

Significant functional tricuspid regurgitation (FTR) represents a poor prognostic factor independent of right ventricular (RV) function. It is usually the consequence of left-sided cardiac diseases that induce RV dilatation and dysfunction, but it can also resulted from right atrial (RA) enlargement and consequent tricuspid annular dilatation. FTR is very frequent among patients with heart failure, particularly in those with reduced LVEF and concomitant functional mitral regurgitation. The development of three-dimensional echocardiography enabled detailed assessment of tricuspid valve anatomy, subvavlular apparatus, and RA and RV changes, as well as accurate evaluation of FTR etiology. Due to high in-hospital mortality risk in patients who were operatively treated for isolated FTR, it has been treated only medically for a long time. Percutaneous approach considers mainly transcatheter tricuspid valve repair (edge-to-edge and annuloplasty) and represents a very attractive option for the high-risk patients. Studies that investigated the effects of different devices showed excellent feasibility and safety, followed by significant reduction in FTR grade, improvement in functional capacity and NYHA class, quality of life, and reduction in hospitalization due to heart failure. Some investigations also reported a decreased mortality in FTR patients. Nevertheless, the results of these investigations should be interpreted with cautious due to the small number of participants and relatively short follow-up. The aim of this review was to summarize the existing data about the clinical importance of FTR and FTR-induced right heart remodeling and currently existing therapeutic approaches for treatment of FTR.

Purpose: The aim of this study was to examine myocardial performance using pressure-strain loops in hypertensive patients with different level of blood pressure control. Material and methods: This cross-sectional study included 204 subjects (45 controls, 70 patients with well-controlled hypertension, 58 patients with uncontrolled hypertension and 31 patients with resistant hypertension) who underwent complete two-dimensional echocardiographic examination including two-dimensional speckle-tracking echocardiography. Pressure-strain curve was used to determine global myocardial work, constructive work, wasted work and work efficiency in all study participants. Results: Left ventricular (LV) longitudinal strain gradually reduced from controls throughout well-controlled hypertensive patients, to patients with uncontrolled and resistant hypertension. Global myocardial work was higher in patients with uncontrolled and resistant hypertension than in controls and well-controlled hypertension. Constructive work was also higher in all hypertensive patients than in controls. Global wasted work and work efficiency were similar between different groups. Global myocardial work index was associated with peak oxygen consumption independently of sex, age, body mass index (BMI), LV structural and functional parameters in all hypertensive participants. Conclusions: Myocardial work was significantly deteriorated in patients with uncontrolled and resistant arterial hypertension compared to controls and well-controlled hypertensive patients. Global myocardial work was associated with functional capacity independent of clinical and echocardiographic parameters.

Home and 24-hour blood pressure (BP Home and BP 24h ) are believed to improve the prognostic value of office BP (BP Office ) alone, but the evidence has limitations such as that (1) these 3 BPs are characterized by multicollinearity and (2) the procedures adopted do not allow quantification of the prognostic advantage. One thousand eight hundred thirty-three individuals belonging to the PAMELA (Pressioni Arteriose Monitorate e Loro Associazioni) were followed for 16 years. Prediction of cardiovascular and all-cause mortality was determined via the goodness of fit of individual data (Cox model), the area underlying the receiving operator curves and the net reclassification improvement of cardiovascular and all-cause mortality risk. Calculations were made for BP Office alone and after addition of BP Home , BP 24h , or both, limited to their residual portion which was found to be unexplained by, and thus independent on, BP Office . With all methods addition of residual out-of-office systolic or diastolic BP to BP Office significantly improved cardiovascular and all-cause mortality prediction. The improvement was more consistent when BP Home rather than BP 24h was added to BP Office and, compared with BP Office plus BP Home , no better prediction was found when addition was extended to BP 24h . With all additions, however, the improvement was quantitatively modest, which was the case also when data were separately analyzed in younger and older individuals or in dippers and nondippers. Thus, addition of out-of-office to BP Office improves prediction of cardiovascular risk, even when data analysis avoids previous limitations. The improvement appears to be limited, however, which raises the question of the advantage to recommend their extended use in clinical practice.

Aim The impact of defining white-coat hypertension (WCH) and white-coat uncontrolled hypertension (WCUH) based on daytime and night-time thresholds of ambulatory blood pressure (ABP), instead of 24-h mean value, is unclear. We aimed to reclassify BP status according to both diurnal and nocturnal thresholds in a large sample of hypertensive patients seen in a specialist center and previously classified as WCH and WCUH based on 24-h BP values. Methods A data-base of 7353 individual 24-h ABP monitoring (ABPM) from untreated and treated hypertensive individuals with office BP at least 140 mmHg and/or 90 mmHg was analysed and a subset of 3223 patients characterized by mean 24-h BP less than 130/80 mmHg (i.e. WCH and WCUH) was included in the present analysis. Results As many as 1281 patients were classified as WCH and 1942 as WCUH. Among them, elevated out-of-office BP according to night-time threshold (i.e. ≥120/70 mmHg) was found in about 30% of cases. In particular, prevalence rates of nocturnal hypertension were 26.9% in WCH and 31.8% in WCUH. Isolated daytime hypertension (i.e. ≥135/85 mmHg) was detected in an additional 4% of individuals. Conclusion Classification of WCH and WCUH based on mean 24-h BP thresholds does not allow to detect an adverse BP phenotype, such as nocturnal hypertension in a large fraction of untreated and treated patients.

Nocturnal hypertension has been recognized as a significant risk factor for cardio- and cerebrovascular diseases. Blood pressure (BP) monitoring significantly increased our awareness of nocturnal hypertension and studies revealed its influence on target organ damage. Nocturnal hypertension is associated with nonphysiological 24-h BP patterns, which consider inadequate drop or even increment of nighttime BP in comparison with daytime BP (nondipping and reverse dipping). Nevertheless, investigations showed that nocturnal hypertension was a predictor of adverse outcome independently of circadian BP pattern. There are still many uncertainties regarding diagnosis, mechanisms and treatment of nocturnal hypertension. There is a small difference between American and European guidelines in cutoff values defining nocturnal hypertension. Pathophysiology is also not clear because many conditions such as diabetes, metabolic syndrome, obesity, sleep apnea syndrome, and renal diseases are related to nocturnal hypertension and nonphysiological circadian BP pattern, but mechanisms of nocturnal hypertension still remain speculative. Therapeutic approach is another important issue and chronotherapy provided the best results so far. There are studies which showed that some groups of antihypertensive medications are more effective in regulation of nocturnal BP, but it seems that the timing of drug administration has a crucial role in the reduction of nighttime BP and conversion of circadian patterns from nonphysiologic to physiologic. Follow-up studies are necessary to define clinical benefits of nocturnal BP reduction and restoring unfavorable 24-h BP variations to physiological variant.

Masked hypertension (MH) is defined as normal office blood pressure (BP) and elevated ambulatory BP (ABP) or home BP or both. This study assessed the association of MH (ie, isolated home, isolated ABP and dual MH) with echocardiographic left ventricular hypertrophy (LVH). The present analysis of the PAMELA study included 1087 untreated and treated participants with normal office BP and a measurable LV mass (LVM). A total of 193 individuals (17.7%) had any MH (ie, normal office BP, elevated ABP or home BP or both), 48 had dual MH (25%), 62 isolated ambulatory MH (32%), and 83 isolated home MH (43%). Average LVM indexed to body surface area was superimposable in the three MH phenotypes (being the largest difference between groups

New antidiabetic therapy that includes sodium-glucose co-transporter 2 (SGLT2) inhibitors, glucagon-like peptide-1 receptor (GLP-1R) agonists, and dipeptidyl peptidase 4 (DPP-4) inhibitors showed significant benefit on cardiovascular outcomes in patients with and without type 2 diabetes mellitus, and this was particularly confirmed for SGLT2 inhibitors in subjects with heart failure (HF) with reduced ejection fraction (HFrEF). Their role on patients with HF with preserved ejection fraction (HFpEF) is still not elucidated, but encouraging results coming from the clinical studies indicate their beneficial role. The role of GLP-1R agonists and particularly DPP-4 inhibitors is less clear and debatable. Findings from the meta-analyses are sending positive message about the use of GLP-1R agonists in HFrEF therapy and revealed the improvement of left ventricular (LV) diastolic function in HFpEF. Nevertheless, the relevant medical societies still consider their effect as neutral or insufficiently investigated in HF patients. The impact of DPP-4 inhibitors in HF is the most controversial due to conflicting data that range from negative impact and increased risk of hospitalization due to HF, throughout neutral effect, to beneficial influence on LV diastolic dysfunction. However, this is a very heterogeneous group of medications and some professional societies made clear discrepancy between saxagliptin that might increase risk of HF hospitalization and those DPP-4 inhibitors that have no effect on hospitalization. The aim of this review is to summarize current clinical evidence about the effect of new antidiabetic medications on LV diastolic function and their potential benefits in HFpEF patients.

The aim of this study was to evaluate the short- and long-term blood pressure (BP) variability and right ventricular (RV) remodeling in women with gestational hypertension and preeclampsia, as well as their association. This cross-sectional study included 161 pregnant women (56 normotensive controls, 55 patients with gestational hypertension, and 50 patients with preeclampsia) after 20 weeks of gestation. All women underwent 24-h ambulatory BP monitoring and echocardiographic examination. Our findings showed that 24-h, daytime and nighttime systolic and diastolic BPs, as well as visit-to-visit systolic and diastolic BPs, were significantly higher in women with gestational hypertension and preeclampsia than in control group. Parameters of short- and long-term BP variability gradually increased from controls, throughout women with preeclampsia, to those with gestational hypertension. RV diameter, E/e' and PAP were significantly higher in women with gestational hypertension and preeclampsia than in controls. Global and free wall RV longitudinal strains, as well as corresponding endo- and epicardial strains, gradually reduced from controls to women with preeclampsia. Parameters of short- and long-term BP variability were independently associated with global and free wall RV longitudinal strain. In conclusion, short- and long-term BP variability was higher in women with pregnancy-induced hypertensive disorders. RV diastolic function and mechanics were deteriorated in these women comparing with controls. A significant association between BP variability and RV longitudinal strain underlines the importance of determination of short- and long-term BP variability during pregnancy.

We sought to investigate echocardiography-derived myocardial work in hypertensive patients with different left ventricular (LV) geometric patterns. This cross-sectional study included 211 hypertensive patients (74 with normal LV geometry, 53 with concentric remodeling, 46 with eccentric LV hypertrophy (LVH) and 38 with concentric LVH) who underwent complete two-dimensional echocardiographic examination including two-dimensional speckle-tracking echocardiography. Pressure-strain curve was used to determine parameters of myocardial work. Our findings showed that multidirectional LV strain was lower in patients with eccentric and concentric LVH than in those with normal LV geometry and concentric remodeling. Global myocardial work index and global constructive work were higher in patients with eccentric and concentric LVH than in those with normal LV geometry and concentric remodeling. Global wasted work and global efficacy work were similar between groups with different LV geometry. E/e' and LV mass index were associated with global myocardial work index and global constructive work independently of clinical and echocardiographic parameters. In conclusion, myocardial work was higher in patients with eccentric and concentric LVH than in patients with normal LV geometry and concentric remodeling. Increased blood pressure in patients with concentric LVH in comparison with other LV geometric patterns has significant impact on the final result. LV geometry has significant impact on myocardial work in hypertensive patients.

Aim: Information on systolic dysfunction, as assessed by left ventricular (LV) mechanics in secondary hypertension is still largely limited. We performed a systematic meta- analysis of 2D/3D speckle tracking studies in order to provide an updated comprehensive information on this topic. Methods: The PubMed, OVID-MEDLINE, and Cochrane library databases were analysed to search for articles published from the inception up to March 31st 2021. Studies were identified by using MeSH terms and crossing the following search items: “myocardial strain” “left ventricular mechanics”, “speckle tracking echocardiography”, “systolic dysfunction”, “hypertensive heart disease”, “left ventricular hypertrophy”, “secondary hypertension”, “primary aldosteronism”, “pheochromocytoma”, “Cushing disease”, “renal artery stenosis”. Results: On the whole, 515 patients with secondary hypertension (169 pheochromocytoma, 165 primary aldosteronism, 144 renal artery stenosis and 37 Cushing's syndrome) and 601 essential hypertensive patients from 11 studies were considered. Pooled ejection fraction (EF) was similar in essential hypertensive controls and in patients with secondary hypertension (SMD 0.12±0.06, CI: 0.001/0.25, p=0.05). Of note, EF was higher in patients with pheochromocytoma than in essential hypertensives (0.50±0.11, CI: 0.27/0.73, p

AIM We sought to assess the long-term changes in aortic root diameter in a population-based sample, focusing on new-onset aortic root dilatation, as well as on the demographic and clinical variables independently related to this dynamic process. METHODS A total of 1122 participants with measurable echocardiographic parameters at baseline and after a 10-year follow-up were included in the analysis. Sex-specific upper limits of normality for absolute aortic root diameter, aortic root diameter indexed to body surface area (BSA) and to height were derived from 712 healthy normotensive PAMELA participants. RESULTS Over the 10-year follow-up, new aortic root dilatation occurred in 3.4% (aortic root /BSA), 4.4% (aortic root /height) and 7.3% (absolute aortic root), respectively. No substantial relationship was observed between baseline office and ambulatory blood pressure (BP) or their changes over time and incident aortic root /BSA and aortic root /height dilatation. Baseline aortic root diameter and left ventricular mass index (LVMI) emerged as important predictors of aortic root dilation, regardless of the diagnostic criteria used. This was also the case for the 10-year change in LVMI. The strength of association between nonhemodynamic variables and new-onset aortic root dilatation was variable, depending on the definition of the aortic phenotype. CONCLUSION The incidence of aortic root dilatation in a general middle-aged population is a relatively infrequent but not so rare event and scarcely influenced by both office and out-office BP. On the contrary, it is strongly related to LVMI (and its variations over time). From a clinical perspective, this underlines that LVH prevention and regression can reduce the risk of aortic root dilatation in the community.

Evaluating left ventricular function through instantaneous left ventricular deformation parameters might not always be accurate for patients with high fluctuations in blood pressure value due to afterload dependence. Myocardial work (MW) is a more advanced tool that combines global myocardial longitudinal strain (GLS) with LV (left ventricular) systolic pressure. The purpose of this study was to investigate the effect of blood pressure changes on MW indices in the population with normal blood pressure and hypertension in a day. A total of 117 participants (34 control subjects and 83 hypertensive patients) underwent echocardiographic measurements at rest, twice a day. Simultaneously, the brachial blood pressure was also measured. LV pressure‐strain loop (PSL) was used to calculate global work index (GWI), global constructive work (GCW), global wasted work (GWW), and global work efficiency (GWE). The differences in the GLS and MW indices between the groups were compared, and the correlation of blood pressure changes with the changes in GLS and MW indices were evaluated. Compared to the control group, the hypertensive group showed higher GWI, GCW, and GWW but lower GLS and GWE. Absolute changes in blood pressure, GLS, and MW indices in hypertensive patients were significantly higher than that of the control subjects. Blood pressure changes had significant univariate correlation with changes in GLS and MW indices. In conclusion, significant fluctuations in blood pressure could induce changes in MW indices to preserve left ventricular systolic function. Repeated assessment of MW indices is necessary for hypertensive patients with large blood pressure fluctuations.

The study by Triantafyllidi et al. supports the view that regression of subclinical cardiac damage requires an effective 24‐hour blood pressure (BP) control along with a reduction in BP variability and suggests that the assessment of BPV and its modifications during the course of therapy may be an useful approach in predicting the beneficial effects of treatment on cardiac structure. However, some aspects and limitations of this study require caution in drawing firm conclusions. So, further investigation is needed to determine if reduction of BPV is actually associated with a regression in cardiac and extracardiac organ damage to identify which which classes of antihypertensive drugs are most effective in reducing BPV, and to elucidate whether those treatments provide additional clinical benefit, independent of the conventional BP targets.

Aim: Available evidence on systolic dysfunction in systemic hypertension, as assessed by left ventricular (LV) mechanics, is still based on single studies. Thus, we performed a systematic meta-analysis of two-dimensional speckle-tracking studies in order to provide an updated comprehensive information on this issue. Methods: The PubMed, OVID-MEDLINE, and Cochrane library databases were analyzed to search English language articles published from the inception up to 31 December 2020. Studies were identified by using MeSH terms and crossing the following search items: 'myocardial strain', 'left ventricular mechanics', 'speckle tracking echocardiography', 'systolic dysfunction', 'hypertensive heart disease', 'systemic hypertension', 'essential hypertension'. Results: Data from 4276 individuals (2089 normotensive controls and 2187 mostly uncomplicated hypertensive patients) were included. Left ventricular (LV) mass index, relative wall thickness, left atrial volume index and E/e' ratio were significantly higher in hypertensive patients than in normotensive controls. LV ejection fraction did not differ in the two pooled groups (SMD -0.048 ± 0.054, 95% CI -0.20 to 0.10, P = 0.30), whereas LV global longitudinal strain (GLS) was significantly impaired in the hypertensive group (SMD: 1.07 ± 0. 15, 95% CI 0.77-1.36, P < 0.0001). Similar findings were obtained in a sub-analysis restricted to 15 studies in which mean age was similar in cases and controls (SMD 1.21 ± 0.23, 95% CI 0.76-1.67, P = 0.002). Conclusion: The present meta-analysis suggests that GLS assessment unmasks systolic dysfunction undetected by conventional ejection fraction in the uncomplicated hypertension setting and that this parameter should be incorporated into routine work-up aimed to identify hypertension-mediated cardiac damage.

We sought to assess functional capacity in recently diagnosed untreated hypertensive patients with different 24-hour blood pressure (BP) patterns (dipping, non-dipping, extreme dipping, and reverse dipping). This cross-sectional study involved 164 untreated hypertensive patients who underwent 24-hour ambulatory BP monitoring and cardiopulmonary exercise testing. Our findings showed that 24-hour and daytime BP values did not differ between four groups. Nighttime BP significantly and gradually increased from extreme dippers to reverse dippers. There was no significant difference in BPs at baseline and at the peak of exercise among four observed groups. Peak oxygen consumption (peak VO2) was significantly lower in reverse dippers than in dippers and extreme dippers. Heart rate recovery was significantly lower among reverse dippers than in dippers and extreme dippers. Ventilation/carbon dioxide slope (VE/VCO2) was significantly higher in reverse dippers and non-dippers in comparison with dippers and extreme dippers. Non-dipping BP pattern (non-dippers and reverse dippers together) was independently and negatively associated lower heart rate recovery in the first minute and peak VO2. Reverse dipping BP pattern was independently associated not only with heart rate recovery in the first minute and peak VO2, but also with VE/VCO2. In conclusion, untreated hypertensive patients with reverse dipping BP patterns showed significantly worse functional capacity than those with dipping and extreme dipping BP patterns. Circadian BP rhythm is related with functional capacity and should be taken into account in the risk assessment of hypertensive patients.

AIM Although nocturnal hypotension is considered the key factor responsible for the increased cardiovascular risk associated with the extreme dipping (ED) pattern, no information is available on its prevalence in this setting. Therefore, we have assessed this topic in a cohort of patients referred to a single out-patient hypertension center. METHODS A large database of individual 24-hour ambulatory BP recordings from untreated individuals with a history of hypertension and treated individuals with hypertension was analyzed. RESULTS A total of 339 of 7,074 patients (4.5%) exhibited an ED pattern (207 had a nighttime reduction in both systolic and diastolic BP ≥ 20% compared to daytime values and 132 a nighttime reduction in diastolic BP ≥ 20%). Among patients with ED, the prevalence of nocturnal hypotension varied from 9.1% to 45.0% depending on the criteria used (i.e., mean nighttime BP < 90/50 mm Hg or < 100/60 mm Hg), and the prevalence of nocturnal hypertension (i.e., mean nighttime BP ≥ 120/70 mm Hg) was 19.5%. Compared with untreated patients, those taking antihypertensive drugs were more likely to have nocturnal hypotension and less likely to have nocturnal hypertension. CONCLUSIONS Our findings support the view that ED pattern is a condition not always associated with nocturnal hypotension because a large fraction of ED patients has normal or elevated mean BP nocturnal values.

Cross-sectional and longitudinal data analysis of the PAMELA (Pressioni Monitorate E Loro Associazioni) population was performed to assess the association between prehypertension and left ventricular hypertrophy (LVH) at entry and the risk of new-onset LVH associated to this condition in the subset of participants with normal LV mass index (LVMI). A total of untreated 1397 participants with measurable echocardiographic parameters at baseline were considered in the cross-sectional analysis. The longitudinal analysis included 880 participants without LVH at baseline and with measurable LVMI at follow-up examination performed 10 years later. At entry, after adjustment for major confounders LVH prevalence rates (LVM/body surface area) showed a significant, progressive increase from the normotensive (2.1%), to prehypertension (6.7%), and hypertension group (18.3%). The incidence of LVH increased progressively from the normotensive to prehypertension and hypertension group (9.0%, 23.2%, and 36.5%, respectively). The risk of new LVH was significantly greater in prehypertension who progressed to sustained hypertension (odds ratio, 4.21; CI, 1.64–10.83; P =0.003) than in those with persistent prehypertension (odds ratio, 1.89; CI, 0.77–5.11; P =0.21) compared with persistent normotensive participants after adjustment for age, sex, baseline LVMI, obesity, glucose, creatinine, total cholesterol and the use of antihypertensive drugs at follow-up. Further adjustments for changes in body mass index, metabolic variables, and creatinine during the follow-up did not modify the strength of association between prehypertension and new-onset LVH. Our findings offer a new piece of evidence on the association of prehypertension with LVH and support the view that preventive actions for this condition affecting a large fraction of the general population should be intensified.

However, conventional parameters of RV systolic function (tricuspid annular plane excursion (TAPSE), RV myocardial performance index (MPI), and fractional area change (FAC)) are not always able to detect subtle changes in RV function. New evidence indicates a significantly higher predictive value of RV longitudinal strain (LS) over conventional parameters. RVLS showed higher sensitivity and specificity in the detection of RV dysfunction in the absence of RV dilatation, apparent wall motion abnormalities, and reduced global RV systolic function. Additionally, RVLS represents a significant and independent predictor of adverse outcomes in patients with dilated cardiomyopathy (CMP), hypertrophic CMP, arrhythmogenic RV CMP, and amyloidosis, but also in patients with connective tissue diseases and patients with coronary artery disease. Due to its availability, echocardiography remains the main imaging tool for RVLS assessment, but cardiac magnetic resonance (CMR) also represents an important additional imaging tool in RVLG assessment. The findings from the large studies support the routine evaluation of RVLS in the majority of CV patients, but this has still not been adopted in daily clinical practice. This clinical review aims to summarize the significance and predictive value of RVLS in patients with different types of cardiomyopathies, tissue connective diseases, and coronary artery disease., publishedVersion

Right ventricular (RV) systolic function has an important role in the prediction of adverse outcomes, includingmortality, in a wide range of cardiovascular (CV) conditions. Because of complex RV geometry and load dependency of the RV functional parameters, conventional echocardiographic parameters such as RV fractional area change (FAC) and tricuspid annular plane systolic excursion (TAPSE), have limited prognostic power in a large number of patients. RV longitudinal strain overcame the majority of these limitations, as it is angle-independent, less load-dependent, highly reproducible, and measure regional myocardial deformation. It has a high predictive value in patients with pulmonary hypertension, heart failure, congenital heart disease, ischemic heart disease, pulmonary embolism, cardiomyopathies, and valvular disease. It enables detection of subclinical RV damage even when conventional parameters of RV systolic function are in the normal range. Even though cardiac magnetic resonance-derived RV longitudinal strain showed excellent predictive value, echocardiography-derived RV strain remains the method of choice for evaluation of RVmechanics primarily due to high availability. Despite a constantly growing body of evidence that support RV longitudinal strain evaluation in the majority of CV patients, its assessment has not become the part of the routine echocardiographic examination in the majority of echocardiographic laboratories. The aim of this clinical review was to summarize the current data about the predictive value of RV longitudinal strain in patients with pulmonary hypertension, heart failure and valvular heart diseases., publishedVersion

Aim: Available evidence on the association between reverse dipping pattern and subclinical cardiac damage is scanty. We performed a systematic meta-analysis of echocardiographic studies in order to provide an updated and comprehensive information on this issue. Methods: The PubMed, OVID-MEDLINE, and Cochrane library databases were analyzed to search English-language articles published from January from the inception up to 31 July 2020. Studies were identified by using MeSH terms and crossing the following search items: 'reverse dipping', 'nondipping', 'inverted dipping', 'ambulatory blood pressure', 'cardiac damage', 'hypertensive heart disease', 'left ventricular mass', 'left ventricular hypertrophy', and 'echocardiography'. Results: Data from 14 studies including 1429 patients with reverse dipping, 2584 dippers and 3508 nondippers were considered. Left ventricular (LV) mass index and relative wall thickness were greater in reverse dippers than in dippers (SMD: 0.40 ± 0.04 g/m2, P < 0.0001; 0.31 ± 0.07, P < 0.0001) and nondippers (SMD: 0.25 ± 0.04 g/m2, P < 0.0001; 0.21 ± 0.07, P = 0.004). The reverse dipping group had an increased risk of LV hypertrophy compared with dipping (OR = 1.85, CI 1.47-2.32, P < 0.0001) and nondipping group (OR = 1.45, CI 1.19-1.78, P < 0.0001). A significant progressive reduction in the E/A ratio, paralleled by an increase in left atrium diameter occurred from dippers, to nondippers and reverse dippers. Conclusion: The present meta-analysis provides a novel piece of information about the unfavourable association between the reverse dipping pattern and subclinical cardiac alterations and suggests that the detection of this blood pressure phenotype may identify individuals at increased risk for subclinical organ damage.

In 1722 hypertensives recruited for the European Lacidipine Study on Atherosclerosis and treated with atenolol or lacidipine (±additional drugs) during 4 years, we evaluated the long-term reproducibility of dipping, nondipping, extreme dipping, and reverse dipping, an information of key relevance for defining the prognostic impact of these blood pressure (BP) phenotypes. Ambulatory BP was measured at baseline and every year during treatment, allowing repeated classifications of these conditions. Based on systolic BP, at baseline 50.1%, 37.5 %, 4.5 %, and 7.9 % were dippers, nondippers, extreme dippers, and reverse dippers, respectively. Antihypertensive drug treatment reduced the number of dippers and extreme dippers in favor of nondippers and reverse dippers. During treatment, the dipping and nondipping phenotypes were markedly unstable and shifts from one to other phenotypes were even more common in reverse and extreme dippers In only a very small fraction of patients, a given nighttime BP phenotype was persistently found throughout the 4 years. Data were similar for diastolic BP and in subgroups differing for the type of treatment, the treatment complexity, and the achieved on-treatment BP value Poor reproducibility characterized also the absolute nighttime BP reduction as measured by the nighttime BP fall and the night/day BP ratio. Thus nighttime BP phenotypes are all largely inconsistent, their detection over the entire treatment period involving just a minute fraction of the entire patients’ cohort.

AIM: Available evidence on regression of left ventricular (LV) hypertrophy in patients with primary aldosteronism after unilateral adrenalectomy is scanty. We performed a systematic meta-analysis of echocardiographic studies to provide an updated and comprehensive information on this issue. METHODS: The PubMed, OVID-MEDLINE and Cochrane library databases were analyzed to search English-language articles published from 1 January 1990 up to 30 June 2020. Studies were identified by using MeSH terms and crossing the following search items: 'primary aldosteronism' 'Conn's syndrome' 'adrenalectomy', with 'cardiac damage', 'hypertensive heart disease' 'left ventricular mass', 'left ventricular hypertrophy', 'left ventricular hypertrophy regression', 'echocardiography'. RESULTS: A total of 629 hypertensive patients with primary aldosteronism (mean age 49 years, 45% men) were included in 14 studies. Baseline and postintervention pooled mean LV mass/BSA values were 134 ± 4 and 108 ± 3 g/m2 [standard means difference (SMD) -0.42 ± 0.05, confidence interval (CI) -0.52/-0.32, P

Obstructive sleep apnea (OSA) syndrome is the most common sleep-breathing disorder, which is associated with increase cardiovascular morbidity and mortality. OSA increases risk of resistant arterial hypertension, coronary artery disease, heart failure, pulmonary hypertension, and stroke. Studies showed the significant relationship between OSA and cardiac remodeling. The majority of investigations were focused on the left ventricle and its hypertrophy and function. Fewer studies investigated right ventricular structure and function revealing deteriorated diastolic and systolic function. Data regarding left and right ventricular mechanics in OSA patients are scarce and controversial. The results of the studies that were focused on the influence of continuous positive airway pressure and weight reduction on cardiac remodeling revealed favorable effect on left and right ventricular structure and function. Recently published analyses confirmed positive effect of treatment on cardiac mechanics. Deterioration of left and right ventricular mechanics occurs before functional and structural cardiac impairments in the cascade of cardiac remodeling and therefore the assessment of left and right ventricular strain may represent a cornerstone in detection of subtle cardiac changes that develop significantly before other, often irreversible, alterations. Considering the fact that left and right ventricular strains have important predictive value in wide range of cardiovascular diseases, one should consider the evaluation of left and right ventricular strains in the routine echocardiographic assessment at all stages of disease-from diagnosis, during follow-up and evaluation of therapeutic effects. The main aim of this review is to provide the current overview of cardiac mechanics in OSA patients before and after (during) therapy, as well as mechanisms that could be responsible for cardiac changes.

We aimed to investigate short- and long-term blood-pressure (BP) variability and left-ventricular (LV) structure, function, and mechanics in women with gestational hypertension and preeclampsia, as well as the relationship between BP variability and LV mechanics. This cross-sectional study included 140 pregnant women (45 normotensive controls, 50 patients with gestational hypertension and, 45 patients with preeclampsia) after 20 weeks of gestation. All participants underwent 24-h ambulatory BP monitoring and echocardiographic examination, as well as regular clinical BP measurements during each visit. Our results show that 24-h, daytime and nighttime systolic and diastolic BP, as well as visit-to-visit systolic and diastolic BPs, gradually increased from controls across patients with preeclampsia to those with gestational hypertension. Similar changes were observed for 24-h systolic BP-variability indices. LV longitudinal and circumferential strains gradually decreased from controls across women with gestational hypertension to patients with preeclampsia. Radial strain was significantly lower in women with preeclampsia than in controls. Indices of short- and long-term BP variability were independent of BP and demographic and echocardiographic parameters associated with LV longitudinal and circumferential strain. In conclusion, LV mechanics are impaired in women with gestational hypertension and preeclampsia compared with LV mechanics in normotensive controls. Short- and long-term BP variability was higher in patients with hypertensive disorders and was significantly associated with longitudinal and circumferential strains.

AIM Few echocardiographic studies have focused on regression of left ventricular hypertrophy (LVH) in patients with renal artery stenosis after revascularization, with inconsistent results. We performed a systematic meta-analysis of these studies in order to offer a comprehensive information on this topic. METHODS The PubMed, OVID-MEDLINE, and Cochrane library databases were analyzed to search English-language articles published from 1 January 1990 up to 31 March 2020. Studies were identified by crossing the following terms: 'renal artery stenosis', 'renovascular hypertension', 'fibromuscular dysplasia', 'renal artery stenting', 'renal artery surgery' with 'cardiac damage', 'hypertensive heart disease' 'left ventricular mass', 'left ventricular hypertrophy', 'echocardiography'. RESULTS A total of 726 hypertensive patients with renal artery stenosis (mean age 61 years, 64% men, 98% treated, 10% with fibromuscular dysplasia) were included in 13 studies. Baseline and postintervention pooled mean LVM values were 220 ± 15 and 203 ± 19 g, respectively (SMD -0.24 ± 0.06, CI -0.37 to -0.21, P

Aim: Information on systolic dysfunction, as assessed by left-ventricular (LV) mechanics, in patients with pheochromocytoma after surgical treatment is scanty. We performed a systematic meta-analysis of speckle tracking echocardiographic studies to provide an updated comprehensive information on this issue. Methods: The PubMed, OVID-MEDLINE, and Cochrane library databases were analyzed to search for articles published from the inception up to May 31st 2021. Studies were identified using MeSH terms and crossing the following search items: “myocardial strain” “left ventricular mechanics”, “speckle tracking echocardiography”, “systolic dysfunction”, “pheochromocytoma”, and “paraganglioma”. Results: A total of 92 surgically treated patients with pheochromocytoma/paraganglioma were included in 3 longitudinal studies. Successful surgical treatment was associated with a decrease in relative wall thickness (SMD −0.25 ± 0.10, CI −0.45/−0.05, p < 0.01) and an improvement in global longitudinal strain (SMD −0.45 ± 0.10, CI −0.66/−0.24, p < 0.0001). The favorable effects of treatment on LV geometry and mechanics were not accompanied by significant changes in ejection fraction (SMD −0.07 ± 0.10, CI −0.27/0.12, p = 0.44). Conclusions: This meta-analysis adds a new piece of evidence, suggesting that surgical treatment of patients with pheochromocytoma impacts favorably on LV geometry and LV mechanics, and, more importantly, the assessment of LV changes in this setting can no longer rely on conventional echocardiographic parameters such as ejection fraction.

There is no consensus regarding the benefit of antihypertensive therapy on left ventricular structure and function. The most of studies investigated the effect of therapy on left ventricular hypertrophy, less studies were focused on left ventricular diastolic dysfunction and the minority on left ventricular mechanics. The majority of investigations showed positive effect of antihypertensive therapy on regression of left ventricular remodeling. Nevertheless, it is very difficult to distinguish the effect of antihypertensive medication from the effect of blood pressure reduction on left ventricular improvement. The other important issue in these studies is difficulty to distinguish the effect of left ventricular hypertrophy regression from the effect of antihypertensive medications on left ventricular diastolic function and mechanics. The novel findings suggest that the cascade of left ventricular remodeling in hypertensive heart disease begins with mechanical changes, continuous with diastolic dysfunction, and ends with left ventricular hypertrophy. This is very important paradigm because it enables early and timely diagnosis of subclinical left ventricular damage in hypertensive patients and should provide rapid detection of left ventricular function improvement during antihypertensive therapy.

Subclinical abnormalities in cardiac and vascular structure reflect the adverse effects triggered by a variety of risk factors on the cardiovascular (CV) system thereby representing an intermediate step in the cardiovascular continuum; such alterations are recognized as reliable markers of increased cardiovascular risk in different clinical settings including obstructive sleep apnea (OSA). The mechanisms underlying subclinical organ damage (OD) in the OSA setting are multifactorial. Hypoxemia and hypercapnia, induced by repeated collapses of upper airways, have been suggested to trigger a cascade of events such as activation of the sympathetic tone, renin-angiotensin-aldosterone system leading to endothelial dysfunction, vasoconstriction, myocardial and vascular remodeling, and hypertension. Furthermore, coexisting non-haemodynamic alterations such as increased oxidative stress, release of inflammatory substances, enhanced lipolysis and insulin resistance have been reported to play a role in the pathogenesis of both cardiac and extra-cardiac OD. In this article we reviewed available evidence on the association between OSA and subclinical cardiac (i.e., left and right ventricular hypertrophy, left atrial dilatation) and extra-cardiac organ damage (i.e., carotid atherosclerosis, arterial stiffness, microvascular retinal changes, and microalbuminuria). This association is apparently stronger for cardiac and carotid subclinical damage than for other markers (i.e., arterial stiffness and retinal changes) and mostly evident in the setting of severe OSA.

Aim: Findings regarding the extent of persistence over time of normal left ventricular (LV) geometry, a reference healthy echocardiographic phenotype, in the community are scanty. We sought to assess this issue in members of the general population enrolled in the Pressioni Arteriose Monitorate e Loro Associazioni study. Methods: The study included 433 participants who attended the second and third survey of the Pressioni Arteriose Monitorate e Loro Associazioni study performed after 10 and 25 years from the initial evaluation. Data collection included medical history, anthropometric parameters, office, home, ambulatory blood pressure, routine blood examinations and echocardiography. Results: During 25-year follow-up 167 participants showed persistently normal LV mass (LVM) and LV geometry pattern, whereas 266 participants exhibited LV hypertrophy or LV concentric remodelling at any point during study. Compared with participants developing, maintaining or regressing from LV hypertrophy and LV concentric remodelling those with a persistently normal LVM index and geometry were younger (-8 years) and more frequently female (63 vs. 45%), exhibited baseline (and follow-up) lower office and out-of-office blood pressure, BMI, serum creatinine, fasting blood glucose total serum cholesterol and rate of antihypertensive treatment. In multivariate regression analysis age [odds ratio (OR): 0.93, confidence interval (CI): 0.91-0.96, P < 0.0001] BMI (OR: 0.90, CI: 0.83-0.97, P = 0.008), office SBP (OR: 0.97, CI: 0.95-0.99, P = 0.005) and fasting blood glucose (OR: 0.96, CI: 0.93-0.99, P = 0.007) were independently associated with persistent normal LVM index and geometry. Conclusion: The current long-term longitudinal study suggests that persistence of normal LV geometry is associated with normal/optimal SBP, BMI and blood glucose. Thus, a closer control of these risk factors in midlife may increase the likelihood of maintaining normal ventricular geometry and, in turn, reduce the burden of subclinical cardiac organ damage and related complications in advanced age.

Objective We sought to investigate left ventricular (LV) structure, function and mechanics in the patients with leukemia and lymphoma before initiation of chemotherapy, as well as the relationship between hematological malignancies and reduced LV longitudinal strain. Methods This retrospective investigation included 71 patients with leukemia and lymphoma before chemotherapy and 36 healthy controls. All participants underwent echocardiographic examination before initiation of chemotherapy and radiotherapy. Results LV global longitudinal strain (− 20.2 ± 1.7% vs. − 17.9 ± 3.0%, p

Functional capacity represents an important predictor for cardiovascular and all-cause mortality in patients with diabetes mellitus (DM). Impaired cardiopulmonary fitness is frequently seen in DM patients, and it might partly explain morbidity and mortality in these patients. There are several potential reasons that could explain impaired functional capacity in DM patients: hyperglycemia, insulin resistance, endothelial dysfunction, inflammation, microvascular impairment, myocardial dysfunction, and skeletal muscle changes. These changes are partly reversible, and improvement of any of these components might increase functional capacity in DM patients and improve their outcome. Physical activity is related with decreased cardiovascular disease and all-cause mortality in patients with type 2 DM. Diabetic cardiomyopathy is the most important clinical entity in DM patients that involves left ventricular diastolic dysfunction and cardiac autonomic neuropathy, which potentially induce heart failure with preserved ejection fraction. Development of diabetic cardiomyopathy may slow oxygen uptake kinetics and affect the cardiorespiratory fitness in DM patients, but it can also induce development of heart failure. Improvement of functional capacity in DM patients represents an important therapeutic task, and it can be achieved mainly with exercise training and significantly less with pharmacological treatment. Exercise training reduces body weight and improves glycemic control, as well as left ventricular structure and function. The aim of this review was to summarize current knowledge about importance of functional capacity in DM patients, as well as possible mechanisms that could explain the relationship between DM and oxygen kinetics.

Aims: The study sought to evaluate cardiorespiratory fitness in patients with type 2 diabetes mellitus (DM) with different levels of left ventricular (LV) diastolic dysfunction (LVDD). Methods: This investigation included 55 controls and 85 uncomplicated diabetic patients, who underwent laboratory analysis, echocardiographic evaluation and cardiopulmonary exercise testing. All DM subjects were separated into 3 groups using the level of LV diastolic function as main criterion: normal, intermediate and LVDD. Results: Echocardiographic parameters of LV hypertrophy were significantly higher in DM subjects, particularly those with intermediate LV diastolic function and LVDD comparing with controls. The same is valid for parameters of LV diastolic function (E/e′, left atrial volume index and tricuspid regurgitation velocity). Peak oxygen uptake was lower, whereas ventilation/carbon dioxide slope was higher, in DM subjects with intermediate LV diastolic function and LVDD in comparison to controls. In the whole study population HbA1c, LV mass index and mitral E/e′ were independently related with peak oxygen uptake and ventilation/carbon dioxide slope. Conclusions: LVDD significantly impacted functional capacity in DM patients. Glycemic control, LV mass index and LVDD were independently related with peak oxygen consumption and ventilation/carbon dioxide slope in the study population. These results show that timely diagnosis of LVDD and more intensive antidiabetic treatment could prevent target organ damage in DM patients.

Hypertensives present cardiac autonomic dysfunction. Reduction in sleep quality increases blood pressure (BP) and favors hypertension development. Previous studies suggested a relationship between cardiovascular autonomic dysfunction and sleep quality, but it is unclear whether this association is present in hypertensives. Thus, this study evaluated the relationship between sleep quality and cardiac autonomic modulation in hypertensives. Forty‐seven middle‐aged hypertensive men under consistent anti‐hypertensive treatment were assessed for sleep quality by the Pittsburgh Sleep Quality Index (PSQI—higher score means worse sleep quality). Additionally, their beat‐by‐beat BP and heart rate (HR) were recorded, and cardiac autonomic modulation was assessed by their variabilities. Mann‐Whitney and t tests were used to compare different sleep quality groups: poor (PSQI > 5, n = 24) vs good (PSQI ≤ 5, n = 23), and Spearman’s correlations to investigate associations between sleep quality and autonomic markers. Patients with poor sleep quality presented lower cardiac parasympathetic modulation (HR high‐frequency band = 26 ± 13 vs 36 ± 15 nu, P = .03; HR total variance = 951 ± 1373 vs 1608 ± 2272 ms(2), P = .05) and cardiac baroreflex sensitivity (4.5 ± 2.3 vs 7.1 ± 3.7 ms/mm Hg, P = .01). Additionally, sleep quality score presented significant positive correlation with HR (r = +0.34, P = .02) and negative correlations with HR high‐frequency band (r = −0.34, P = .03), HR total variance (r = −0.35, P = .02), and cardiac baroreflex sensitivity (r = −0.42, P = .01), showing that poor sleep quality is associated with higher HR and lower cardiac parasympathetic modulation and baroreflex sensitivity. In conclusion, in treated hypertensive men, poor sleep quality is associated with cardiac autonomic dysfunction.

OBJECTIVE We sought to investigate the predictive value of right ventricular (RV) remodeling and 24-h blood pressure (BP) patterns on long-term cardiovascular prognosis in the initially untreated hypertensive patients. METHODS The current study included 505 initially untreated hypertensive patients who were consequently included in this study from 2007 to 2012. All the patients underwent laboratory analysis, 24-h BP monitoring and echocardiographic examination at baseline. The patients were followed for a median period of 9 years. The adverse outcome was defined as the hospitalization due to cardiovascular events (atrial fibrillation, myocardial infarction, myocardial revascularization, heart failure, stroke, or cardiovascular death). RESULTS During the 9-year follow-up period adverse cardiovascular events occurred in 82 hypertensive patients. Night-time SBP, the nondipping BP pattern, left ventricle hypertrophy, RV hypertrophy, right atrial enlargement, RV diastolic dysfunction, and RV systolic dysfunction were associated with adverse cardiovascular events. Nevertheless, night-time SBP, the nondipping BP pattern, mitral E/e', left ventricle hypertrophy, and RV hypertrophy were the only independent predictors of cardiovascular events. When all four BP patterns were included in the model, only the reverse dipping BP pattern was an independent predictor of cardiovascular events. CONCLUSION The present investigation showed that RV hypertrophy and the reverse dipping BP pattern were independent long-term predictors of the cardiovascular outcome. Detailed echocardiographic evaluation and 24-h ambulatory blood pressure monitoring should be performed even in low-risk hypertensive patients.

Left atrial (LA) structural, functional and mechanical changes have important role in development of diabetic cardiomyopathy and it was discovered that LA remodeling has important prognostic role in the patients with diabetes (DM). Previously the focus of echocardiographic studies in DM population was on the left ventricular structure and function, but the atrioventricular coupling was proved to be one of the main predictors of cardiovascular morbidity and mortality in DM patients. Each phase of LA cycle has determinant role in the atrioventricular coupling and therefore the accurate assessment of LA phasic function gained importance over last decade. The failure of any of the three LA phasic functions (reservoir, conduit or contractile) leads potentially to LA dilatation, left ventricular diastolic dysfunction, atrial fibrillation and ultimately development of heart failure with preserved (or even reduced) ejection fraction. Even though LA phasic function has not been extensively studied in DM population, it is reasonable to hypothesize that LA dysfunction is very frequent in these patients, considering the high prevalence of atrial fibrillation and heart failure in these individuals. In research and clinical purposes two techniques have been used for determination of LA phasic function: volumetric and strain. Although these methods fundamentally differ, with their own advantages and limitations, they also provide comparable results that can direct our therapeutic approach in DM patients. Namely, not only that LA function represents an independent predictor of cardiovascular outcome in DM patients, but also it has been also associated with parameters of glycemic control. This review summarized the current knowledge regarding LA phasic function in DM patients.

Arterial hypertension represents the most frequent cardiovascular risk factor that is associated with cardiac remodeling. Hypertensive heart disease was defined by the presence of left ventricular hypertrophy (LVH) and diastolic dysfunction, and it has been diagnosed by echocardiography in everyday clinical practice. Interstitial myocardial fibrosis is the underlying cause of hypertension-induced cardiac remodeling, and it could not be visualized with different echocardiographic methods. Cardiac magnetic resonance (CMR) and its methods such as late gadolinium enhancement, and T1 mapping provides qualitative and quantitative assessment of interstitial myocardial fibrosis in hypertensive patients. Furthermore, CMR can provide differentiation of LVH between hypertensive patients and cardiomyopathies (hypertrophic or Fabry disease). Timely diagnosis of cardiac impairment and early treatment is essential because regression of LVH could be achieved with adequate treatment. Diffuse cardiac fibrosis in hypertensive patients might be an underlying mechanism that explains the increased cardiovascular morbidity and mortality in this population. Future longitudinal investigations are necessary to determine causal relationship between diffuse fibrosis and cardiovascular outcome in these patients. The aim of this review is to summarize the current knowledge regarding CMR techniques and their potential usage in patients with hypertensive heart disease.

Diabetes cardiomyopathy is a specific form of cardiac disease characteristic for diabetic patients. Development of echocardiography enabled diagnosis of diabetic cardiomyopathy significantly before the occurrence of heart failure. Previously was believed that left ventricular (LV) diastolic dysfunction represents the first detectable stage of diabetic cardiomyopathy. However, speckle tracking imaging and strain evaluation showed that mechanical changes occur before LV diastolic dysfunction. Nevertheless, it seems that the first detectable stage of diabetic cardiomyopathy is myocardial interstitial fibrosis, which currently could be diagnosed predominantly by cardiac magnetic resonance. T1 mapping evaluation before and after contrast injection enables assessment of extracellular volume (ECV) and provides qualitative and quantitative assessment of interstitial myocardial fibrosis in diabetic patients. Studies showed a strong correlation between ECV-parameter of interstitial fibrosis and level of glycated hemoglobin-main parameter of glucose control in diabetes. This stage of fibrosis is still not LV hypertrophy and it is reversible, which is of a great importance because of timely initiation of treatment. The necessity for early diagnose is significantly increasing due to the fact that diabetes and arterial hypertension are concomitant disorders in the large number of diabetic patients and it has been known that the risk of interstitial myocardial fibrosis is multiplied in patients with both conditions. Future follow-up investigations are essential to determine the causal relationship between interstitial fibrosis and outcome in these patients. The aim of this review was to summarize the current knowledge and clinical usefulness of CMR in diabetic patients.

Aim Information regarding the association of hypertension-mediated organ damage (HMOD) with extreme dipping pattern is scanty and not univocal. We sought to assess the clinical correlates of this blood pressure (BP) phenotype and its relationship with cardiac HMOD in the general population belonging to Pressioni Arteriose Monitorate E Loro Associazioni (PAMELA) study. Methods The present analysis included all participants with good-quality ABPM recordings with reliable echocardiography at entry. Results A total of 792 out of 1597 patients (49.6%) exhibited an extreme dipping pattern (155 had a night-time reduction in both SBP and DBP at least 20% compared with daytime values and 637 a night-time reduction in DBP at least 20%); 34.2% were dippers and 16.2% nondippers. Left ventricular mass (LVM) indexed to height and LV hypertrophy (LVH) prevalence rates increased progressively from diastolic extreme dipping (14%), dipper (17%), systolic/diastolic extreme dipping (21%) to nondipper group (27%). However, after adjusting for confounders, statistical differences in both LVMI and LVH rates among the four groups disappeared. Similar results were obtained for LVM indexed to body surface area and absolute/indexed left atrial diameter. Conclusion Extreme dipping pattern is a BP phenotype highly frequent in the general population largely consisting of middle-aged individuals without prevalent cardiovascular disease. In this population, the extreme dipping pattern is not associated with an increased risk of cardiac HMOD, which suggests that the mechanisms invoked for the potential adverse cardiovascular effects of this condition (i.e. nocturnal hypoxemia, low-grade myocardial inflammation, coronary hypoperfusion, sympathetic activation at early morning, etc.) are not operative.

We aimed to investigate myocardial performance using pressure‐strain loops in hypertensive patients with and without type 2 diabetes mellitus (DM). This cross‐sectional study included 165 subjects (55 controls, 60 hypertensive patients without DM, and 50 hypertensive patients with DM) who underwent complete two‐dimensional echocardiographic examination (2DE) including two‐dimensional speckle‐tracking echocardiography. Pressure‐strain curve was used to determine global myocardial work index, constructive work, wasted work, and work efficiency in all study participants. Left ventricular (LV) longitudinal and circumferential strains gradually reduced from controls throughout hypertensive subjects to patients with DM and hypertension. Global myocardial work index gradually increased from controls, throughout hypertensive patients to subjects with hypertension and DM (1887 ± 289 vs 2073 ± 311 vs 2144 ± 345 mm Hg%, P = .001). Constructive work increased in the same direction (2040 ± 319 vs 2197 ± 344 vs 2355 ± 379 mm Hg%, P

AIM: Findings regarding the association of left ventricular mass (LVM) and new-onset hypertension are based on blood pressure measured in the office. We sought to assess the value of LVM in predicting in-office and out-of-office incident hypertension in members of the general population enrolled in the Pressioni Monitorate E Loro Associazioni study. METHODS: The study included participants with normal office (n = 792), home (n = 714) and 24-h (n = 825) ambulatory blood pressure (ABP) at baseline evaluation who had a readable echocardiogram at entry and at the end of follow-up. Each normotensive group was divided into quartiles of LVM indexed (LVMI) to height. RESULTS: Over a follow-up of 148 months cumulative incidence of new office, home and 24-h ABP hypertension were 35.9, 30.7 and 36.1%, respectively. In fully adjusted models (including age, sex, BMI change during follow-up, baseline serum glucose, creatinine, total cholesterol office, home and 24-h SBP and DBP). higher LVMI values (i.e. the highest vs. the lowest quartile) were independently associated with an increased risk of home [odds ratio (OR) = 2.14, 95% confidence interval (CI) 1.21-3.77, P = 0.008] and 24-h ABP hypertension (OR = 1.70, 95% CI 1.05-2.76, P = 0.03). This was not the case for new-onset office hypertension (OR = 1.61, 95% CI 0.94-2.74, P = 0.07). CONCLUSION: Our study provides the first evidence that in normotensive individuals the magnitude of LVMI is independently associated with the risk of incident out-of-office hypertension.
