RESUMO
Takotsubo syndrome (TTS) might exhibit particular chronobiological patterns in its onset, characterized by variations according to time of the day, day of the week, and month of the year. The aim of this study was to fully explore the temporal patterns (circadian, weekly and seasonal) in the onset of TTS. A systematic review and meta-analysis of literature were conducted for studies (2006-2024) reporting the temporal patterns (circadian, weekly and/or seasonal) in the onset of TTS. Among the 4257 studies retrieved, 20 (including 64,567 subjects) fulfilled all eligibility criteria. Data were aggregated used random effects model as pooled risk ratio and the attributable risk (AR). The proportion analysis (including 8 studies; n=853) showed a decreasing pattern of the pooled rates of TTS shifting from the morning to the night (pooled TTS rates: 34.0%; 32.1%; 21.7%; 12.7% in the morning, afternoon, evening and night, respectively). The same pattern was observed stratifying by type of preceding stressful factor or event, considering physical stressors (pooled rates in the morning and night: 37.6% and 9.8%, respectively), and also in case no event could be identified. The pooled rates of TTS onset peaked on Monday and Tuesday (17.3% and 18.4% respectively), then declined during the week, reaching the lowest rates on Friday and Saturday (10.6% and 10.8%, respectively), with no sex differences. TTS onset reached the highest values on summer, and the lowest in winter (27.9% versus 21.7% in summer and winter, respectively). The TTS morning peak based analyses (â¼33% of all the registered events) account for a RR of 1.46 (95% CI: 1.38-1.54), the week-based for a RR of 1.26 (1.16-1.35), the season-based for a RR of 1.04 (1.04-1.05). TTS onset exhibits specific chronobiological patterns, characterized by a peak during the morning hours, and on Monday and Tuesday. Differing from other cardiovascular emergencies TTS was more frequent during summer. Further studies are needed to fully understand the underlying pathophysiological mechanisms in order to tailor relative management and preventive strategies.
RESUMO
The optimal management of heart valve disease (HVD) is still debated and many studies are underway to identify the best time to refer patients for the most appropriate treatment strategy (either conservative, surgical or transcatheter interventions). Exercise pulmonary hypertension (PH) can be detected during exercise stress echocardiography (ESE) and has been demonstrated to have an important prognostic role in HVD, by predicting symptoms and mortality. This review article aims to provide an overview on the prognostic role of exercise PH in valvulopathies, and its possible role in the diagnostic-therapeutic algorithm for the management of HVD.
RESUMO
Background/Objectives: Severe aortic stenosis (AS) is the most frequent valvular heart disease. Models for stratifying cardiac damage associated with aortic stenosis have been developed to predict outcomes following valve replacement. However, evidence regarding morphological and functional evolution, as well as potential changes in the degree of cardiac damage, is limited. We aim to provide information on the evolution of cardiac morphology and the function of patients undergoing transcatheter aortic valve replacement (TAVR) who have been classified using a cardiac damage staging system. Methods: In total, 496 patients were included in the analysis, and were classified into four stages based on the extent of cardiac damage as follows: Stage 0, no cardiac damage: left ventricle global longitudinal strain (LV-GLS) < -17%; right ventricular-arterial coupling (RVAc) ≥ 0.35), and absence of significant mitral regurgitation (MR). Stage 1, left-sided subclinical damage: LV-GLS ≥ -17%. Stage 2, left-sided damage: significant MR. Stage 3, right-sided damage: RVAc < 0.35. Results: The mean age was 82.1 ± 5.9 years, and 53.0% were female. In total, 24.5% of patients met the criteria for Stage 0, and Stage 1 included 42.8% of patients, Stage 2 included 16.5%, and Stage 3 comprised 16.2% of patients. Mortality was 8.4% for stage 0, 17.4% for stage 1, 25.6% for stage 2, and 28.6% for stage 3 patients (p = 0.004). Diabetes mellitus (DM) (p = 0.047) and chronic kidney disease (CKD) (p = 0.024) were the only clinical predictors of no change or worsening in the stage of cardiac damage. Regarding echocardiographic variables, concomitant tricuspid, and mitral regurgitation, ≥ 2 were both significantly associated with no change or worsening, also (p < 0.001). Conclusions: Cardiac damage that is secondary to severe aortic stenosis has morphological and functional repercussions that, even after valve replacement, persist and might worsen the prognosis.
RESUMO
INTRODUCTION: No data are available on the diagnostic algorithms recommended by guidelines for the assessment of diastolic dysfunction (DD) in patients with arterial hypertension. AIM: To fill this gap, we evaluated diastolic function in hypertensive patients with and without LVH matched with healthy subjects by applying 2016 American Society of Echocardiography-European Association of Cardiovascular Imaging Guidelines for the evaluation of LV diastolic function. METHODS: 717 healthy and hypertensives with normal LV ejection fraction and with and without LV hypertrophy (LVH), matched 1:1:1 from two prospective registries, represented the study population. RESULTS: By applying algorithm A, indeterminate pattern was found in 0.4% of healthy, in 6.3% of hypertensives without LVH, and in 21% with LVH (overall p < 0.05 vs. healthy). DD was absent in healthy, however present in 2 and 8% of hypertensives without and with LVH (p = 0.06 and p = 0.001 vs. healthy, respectively). By applying algorithm B, no cases of indeterminate pattern were found. DD was observed in 2.9% of healthy, 7 and 10.5% of hypertensives without and with LVH (p < 0.05 vs. healthy). CONCLUSIONS: The use of algorithm A should be limited only to truly normal subjects, whereas algorithm B should be applied to all patients with hypertension, even without comorbidities and irrespective of LVH.

A substantial number of patients may experience systemic inflammatory response syndrome (SIRS) and related adverse events after transcatheter aortic valve implantation and endovascular aortic aneurysm repair. Although a clear etiology has not been established, endothelial disruption and tissue-ischemic response secondary to the foreign material may represent the trigger events. A latency period (0 to 48 hours) may occur between the initial injury and onset of symptoms mirroring an initial local response followed by a systemic response. Clinical presentation can be mild or severe depending on external triggers and characteristics of the patient. Diagnosis is challenging because it simulates an infection, but lack of response to antibiotics, negative cultures are supportive of SIRS. Increased in-hospital stay, readmissions, major cardiovascular events, and reduced durability of the device used are the main complications. Treatment includes non-steroidal anti-inflammatory drugs or corticosteroids. In conclusion, further studies are warranted to fully explore pathophysiologic mechanisms underpinning SIRS and the possibility of enhancing device material immune compatibility to reduce the inflammatory reaction of the host tissue.

Knowledge about the Health-related Quality of Life (HR-QoL) after Type A (TA-AAD) and Type B acute aortic dissection (TB-AAD) is still insufficient. Through this systematic review, including 22 studies (16 for TA-AAD and 6 TB-AAD -1998-2023), the entire literature on HR-QoL after surgical and/or endovascular and/or medical interventions has been investigated. In TA-AAD patients, despite overall SF-36 score was similar to the standard population, with > 80 years patients displaying a better emotional domain, the SF-12 was significant lower to controls in physical and mental well-being domains. Exercise-based cardiac rehabilitation improved HR-QoL. In TB-AAD, vitality and mental health SF-36 scores improved after thoracic endovascular aortic repair (TEVAR); long-term QoL was similar in the open surgery group compared to TEVAR. Overall, HR-QoL after AAD seems adequate irrespective of age or sex, except for some specific domains. Physical exercise and cardiac rehabilitation may improve HR-QoL in these patients.

Despite guideline recommendations, strategies for implementing cardiac rehabilitation (CR) in patients with acute aortic dissection (AAD) are not well established with little evidence to risk stratify prudent and effective guidelines for the many required variables. We conducted a systematic review of studies (2004-2023) reporting CR following type A (TA) and type B (TB) AAD. Our review is limited to open surgical repair for TA and medical treatment for TB. A total of 5 studies were included (4 TA-AAD and 1 TB-AAD) in the qualitative analysis. In general, observational data included 311 patients who had an overall favorable effect of CR in AAD consisting of a modestly improved exercise capacity and work load during cycle cardiopulmonary exercise test (TB-AAD), and improved quality of life (QoL). No adverse events were reported during symptom limited pre-CR treadmill or cycle exercise VO2 max or CR. Given the overall potential in this high risk population without adequate evidence for important variables such as safe time from post-op to CR, intensity of training, duration and frequency of sessions and followup it is time for a moderate sized well designed safe trial for patients' post-op surgery for TA-AAD and medically treated TB-AAD who are treated with standardized evidence based medical therapy and physical therapy from discharge randomized to CR versus usual care.

PURPOSE: Our study aimed to describe the efficacy and safety of oral anticoagulation (OAC) use in octogenarians with atrial fibrillation (AF) across the spectrum of renal function. METHODS: Data for this study were sourced from AF Research Database (NCT03760874). AF patients aged ≥ 80 who received OAC treatment, both direct oral anticoagulant (DOAC) and vitamin K antagonist (VKA) were selected. Participants were categorized in 2 groups according to creatinine clearance (CrCl) ≥ 45 and < 45 ml/min/1.73 m2. The primary safety outcome was the occurrence major bleeding. The primary effectiveness outcome was the occurrence of thromboembolic events. RESULTS: A total of 901 AF patients (median age 84 [4.9] years; 44% men) with age ≥ 80 years on treatment with DOACs (n: 629, 70%) and VKA (n: 272, 30%) were included in the study. 303 patients (34%) had CrCl < 45 ml/min/1.73m2 and 598 (66%) had CrCl ≥ 45 ml/min/1.73m2. No significant differences were shown in major bleedings, minor bleedings and thromboembolic events between patients on DOACs vs VKAs, both in the group with CrCl ≥ 45 than < 45 ml/min. In the group with CrCl < 45 ml/min/1.73 m2, a total of 72 patients (23%) died during the follow-up, with higher mortality in VKA group compared to DOACs (45% vs 15%; p < 0.001). At multivariate regression analysis, age [OR: 1.15; p = 0.001] and coronary artery disease (CAD) [OR: 1.74; p = 0.04] were independently associated with mortality; in contrast, the use of DOACs were inversely associated with mortality [OR = 0.26; p < 0.001]. In patients with CrCl ≥ 45 ml/min/1.73 m2, DOACs group experienced less intra-cranial hemorrhage (ICH) (0.2% vs 2.8%; p = 0.01) compared to VKAs. VKAs patients showed higher mortality compared to those on DOACs (29.1% vs 7.9%; p < 0.001). At multivariate regression analysis, chronic heart failure [OR = 2.14; p = 0.01] was independently associated with death, whereas male gender [OR: 0.45; p = 0.009] and the use of DOACs [OR: 0.29; p < 0.001] were associated with lower mortality. CONCLUSION: DOACs seem to be safe and effective in octogenarians with chronic kidney disease at stage ≥ G3b. As compared with VKA administration, the use of DOACs was associated with lower mortality rates among AF octogenarians with renal dysfunction.
RESUMO
BACKGROUND: Exercise echocardiography is used for assessment of pulmonary circulation and right ventricular function, but limits of normal and disease-specific changes remain insufficiently established. OBJECTIVES: The objective of this study was to explore the physiological vs pathologic response of the right ventricle and pulmonary circulation to exercise. METHODS: A total of 2,228 subjects were enrolled: 375 healthy controls, 40 athletes, 516 patients with cardiovascular risk factors, 17 with pulmonary arterial hypertension, 872 with connective tissue diseases without overt pulmonary hypertension, 113 with left-sided heart disease, 30 with lung disease, and 265 with chronic exposure to high altitude. All subjects underwent resting and exercise echocardiography on a semirecumbent cycle ergometer. All-cause mortality was recorded at follow-up. RESULTS: The 5th and 95th percentile of the mean pulmonary artery pressure-cardiac output relationships were 0.2 to 3.5 mm Hg.min/L in healthy subjects without cardiovascular risk factors, and were increased in all patient categories and in high altitude residents. The 5th and 95th percentile of the tricuspid annular plane systolic excursion to systolic pulmonary artery pressure ratio at rest were 0.7 to 2.0 mm/mm Hg at rest and 0.5 to 1.5 mm/mm Hg at peak exercise, and were decreased at rest and exercise in all disease categories and in high-altitude residents. An increased all-cause mortality was predicted by a resting tricuspid annular plane systolic excursion to systolic pulmonary artery pressure <0.7 mm/mm Hg and mean pulmonary artery pressure-cardiac output >5 mm Hg.min/L. CONCLUSIONS: Exercise echocardiography of the pulmonary circulation and the right ventricle discloses prognostically relevant differences between healthy subjects, athletes, high-altitude residents, and patients with various cardio-respiratory conditions.

At our Pneumology Department, we dealt with three waves of COVID-19 pandemics. The purpose of this study is to compare patients' epidemiological and clinical characteristics across waves and to assess the effect of vaccination on clinical presentation, course, and prognosis. From March 2020 to March 2022, a retrospective cohort study was conducted to compare patient characteristics. Based on the time of hospital admission, data from 456 patients were collected and divided into three groups (IW, IIW, and IIIW). In addition, we looked at the link between vaccination and clinical presentation and hospitalization outcome. The average age and comorbidities of patients increased, as did the worsening of respiratory conditions at admission (PaO2/FiO2 median 207 in IW, 95.5 in IIW, and 99 in IIIW). Continuous positive airway pressure (CPAP) was the primary respiratory support during the first wave, but an increase in the use of high flow nasal cannula and noninvasive ventilation was later observed, resulting in a higher hospital discharge rate and a lower intubation rate. Vaccinated patients had less severe COVID-19-related respiratory failure, a better clinical course, and a higher hospital discharge rate (71.4% in V-group vs 44.7% in NV-group, p<0.001). Patients' characteristics changed over the three waves, possibly due to virus mutations. The advancement of clinical and therapeutic management knowledge has contributed to a reduction in the severity of respiratory failure. The vaccination campaign improved the clinical course and reduced mortality.
RESUMO
Obesity is an increasingly widespread disease worldwide because of lifestyle changes. It is associated with an increased risk of cardiovascular disease, primarily type 2 diabetes mellitus, with an increase in major cardiovascular adverse events. Bariatric surgery has been shown to be able to reduce the incidence of obesity-related cardiovascular disease and thus overall mortality. This result has been shown to be the result of hormonal and metabolic effects induced by post-surgical anatomical changes, with important effects on multiple hormonal and molecular axes that make this treatment more effective than conservative therapy in determining a marked improvement in the patient's cardiovascular risk profile. This review, therefore, aimed to examine the surgical techniques currently available and how these might be responsible not only for weight loss but also for metabolic improvement and cardiovascular benefits in patients undergoing such procedures.
RESUMO
ABSTRACT: Sodium-glucose cotransporter 2 inhibitors (SGLT2-i) are a novel class of oral hypoglycemic agents currently used among patients with type 2 diabetes mellitus (T2DM). The effects of SGLT2-i inhibitors on cardiac structure and function are not fully understood. The aim of this study is to evaluate the echocardiographic changing among patients with well-controlled T2DM treated with SGLT2-i in real-world setting. Thirty-five well-controlled T2DM patients (65 ± 9 years, 43.7% male) with preserved left ventricular ejection fraction (LVEF) and 35 age and sex-matched controls were included. T2DM patients underwent clinical and laboratory evaluation; 12-lead surface electrocardiogram; 2-dimensional color Doppler echocardiography at enrolment, before SGLT2-i administration, and at 6 months follow-up after an uninterrupted 10 mg once daily of empagliflozin (n: 21) or dapagliflozin (n: 14). Standard echocardiographic measurements, LV global longitudinal strain (LV-GLS), global wasted work, and global work efficiency were calculated. T2DM patients showed higher E\E' ratio (8.3 ± 2.5 vs. 6.3 ± 0.9; P < 0.0001 ) and lower LV-GLS (15.8 ± 8.1 vs. 22.1 ± 1.4%; P < 0.0001 ) and global myocardial work efficiency (91 ± 4 vs. 94 ± 3%; P: 0.0007 ) compared with age and sex-matched controls. At 6-month follow-up, T2DM patients showed a significant increase in LVEF (58.9 ± 3.2 vs. 62 ± 3.2; P < 0.0001 ), LV-GLS (16.2 ± 2.8 vs. 18.7 ± 2.4%; P = 0.003 ), and global work efficiency (90.3 ± 3.5 vs. 93.3 ± 3.2%; P = 0.0004 ) values; conversely, global wasted work values (161.2 ± 33.6 vs. 112.72 ± 37.3 mm Hg%; P < 0.0001 ) significantly decreased. Well-controlled T2DM patients with preserved LVEF who are treated with a SGLT2-i on top of the guidelines direct medical therapy showed a favorable cardiac remodeling, characterized by the improvement of LV-GLS and myocardial work efficiency.

AIM: we sought to test the inter-center reproducibility of 16 echo laboratories involved in the EACVI-Afib Echo Europe. METHODS: This was done on a dedicated setting of 10 patients with sinus rhythm (SR) and 10 with persistent atrial fibrillation (AF), collected by the Principal Investigator. Images and loops of echo-exams were stored and made available for labs. The tested measurements included main echo-Doppler parameters, global longitudinal strain (GLS) and peak atrial longitudinal strain (PALS). RESULTS: Single measures interclass correlation coefficients (ICCs) of left ventricular mass and ejection fraction were suboptimal in both patients with SR and AF. Among diastolic parameters, ICCs of deceleration time were poor, in particular in AF (=.50). ICCs of left atrial size and function, besides optimal in AF, showed an acceptable despite moderate concordance in SR. ICC of GLS was .81 and .78 in SR and AF respectively. ICCs of PALS were suitable but lower in 4-chamber than in 2-chamber view. By depicting the boxplot of the 16 laboratories, GLS distribution was completely homogeneous in SR, whereas GLS of AF and PALS of both SR and AF presented a limited number of outliers. GLS mean ± SE of the 16 labs was 19.7 ± .36 (95% CI: 18.8-20.4) in SR and 16.5 ± .29 (95% CI: 15.9-17.1) in AF, whereas PALS mean ± SE was 43.8 ± .70 (95% CI: 42.3-45.3) and 10.2 ± .32 (95% CI: 9.5-10.9) respectively. CONCLUSION: While the utilization of some standard-echo variables should be discouraged in registries, the application of GLS and PALS could be largely promoted because their superior reproducibility, even in AF.

Myotonic dystrophy type 1 (DM1) is the most common muscular dystrophy in adults. Cardiac involvement is reported in 80% of cases and includes conduction disturbances, arrhythmias, subclinical diastolic and systolic dysfunction in the early stage of the disease; in contrast, severe ventricular systolic dysfunction occurs in the late stage of the disease. Echocardiography is recommended at the time of diagnosis with periodic revaluation in DM1 patients, regardless of the presence or absence of symptoms. Data regarding the echocardiographic findings in DM1 patients are few and conflicting. This narrative review aimed to describe the echocardiographic features of DM1 patients and their prognostic role as predictors of cardiac arrhythmias and sudden death.
RESUMO
Cardiovascular (CV) diseases (CVD) are a major cause of long-term morbidity and mortality affecting life expectancy amongst cancer survivors. In recent years, because of the possibility of early diagnosis and the increased efficacy of neo-adjuvant and adjuvant systemic treatments (targeting specific molecular pathways), the high percentage of survival from breast cancer led CVD to become the first cause of death among survivors. Therefore, it is mandatory to adopt cardioprotective strategies to minimize CV side effects and CVD in general in breast cancer patients. Cancer therapeutics-related cardiac dysfunction (CTRCD) is a common group of side effects of chemotherapeutics widely employed in breast cancer (e.g., anthracycline and human epidermal growth factor receptor 2 inhibitors). The aim of the present manuscript is to propose a pragmatic multidisciplinary stepwise approach for prevention, early detection, and treatment of cardiotoxicity in patients with breast cancer.
RESUMO
Early detection and treatment of cancer have led to a noticeable reduction in both mortality and morbidity. However, chemotherapy and radiotherapy could exert cardiovascular (CV) side effects, impacting survival and quality of life, independent of the oncologic prognosis. In this regard, a high clinical index of suspicion is required by the multidisciplinary care team in order to trigger specific laboratory tests (namely natriuretic peptides and high-sensitivity cardiac troponin) and appropriate imaging techniques (transthoracic echocardiography along with cardiac magnetic resonance, cardiac computed tomography, and nuclear testing (if clinically indicated)), leading to timely diagnosis. In the near future, we do expect a more tailored approach to patient care within the respective community along with the widespread implementation of digital health tools.
