Platelet inhibition with orodispersible ticagrelor in acute coronary syndromes according to morphine use: the TASTER study final results.

AIM: To date, it is still unknown whether orodispersible tablet (ODT) ticagrelor might represent a suitable way to reach a proper antiaggregation in acute coronary syndrome (ACS) patients receiving morphine. Aim of the present study was to evaluate platelet inhibition with 180 mg ticagrelor loading dose (LD) administered as ODT compared with standard coated tablet ticagrelor formulation in ACS patients undergoing percutaneous coronary intervention (PCI) according to morphine use. METHODS AND RESULTS: One-hundred and 30 patients presenting with STEMI or very high-risk NSTE-ACS were randomly assigned to receive ODT or standard ticagrelor LD. Potential morphine-ticagrelor interaction was assessed by stratified randomization according to morphine use. Platelet reactivity was evaluated by Platelet Reactivity Units (PRU) VerifyNow™ 1, 2, 4, and 6 h after ticagrelor LD. The primary endpoint was residual platelet reactivity 1 h after LD across the two ticagrelor formulation and according to morphine use. Safety endpoints were major bleedings and other in-hospital ticagrelor administration-related adverse events. One hour after LD, PRU median value was higher in morphine-treated patients (N = 32) as compared with patients not receiving morphine (N = 98; PRU = 187 [70-217]) vs. 73 [7-187]; P = 0.012). In patients with morphine, 1-h PRU values were similar between study groups (192 [114-236] vs. 173 [16-215] in ODT and standard tablet ticagrelor, respectively). Similarly, in patients without morphine, 1-h PRU values were not significantly different between study groups (69 [8-152] vs. 110 [6-193] in ODT and standard tablet ticagrelor, respectively). Platelet reactivity appeared similar in the 2 study arms at 2, 4, and 6 h after LD. No significant difference was observed among patients with or without morphine regarding in-hospital adverse events or drug side-effects, even if a reinfarction due to acute stent thrombosis was observed in a patient treated with morphine. CONCLUSIONS: There was no difference between ODT and standard ticagrelor tablets in terms of post-LD residual platelet reactivity, percentage of platelet inhibition or safety regardless to morphine use.

Echocardiographic heart ageing patterns predict cardiovascular and non-cardiovascular events and reflect biological age: the SardiNIA study.

AIMS: Age is a crucial risk factor for cardiovascular (CV) and non-CV diseases. As people age at different rates, the concept of biological age has been introduced as a personalized measure of functional deterioration. Associations of age with echocardiographic quantitative traits were analysed to assess different heart ageing rates and their ability to predict outcomes and reflect biological age. METHODS: Associations of age with left ventricular mass, geometry, diastolic function, left atrial volume, and aortic root size were measured in 2614 healthy subjects. Based on the 95% two-sided tolerance intervals of each correlation, three discrete ageing trajectories were identified and categorized as "slow", "normal", and "accelerated" hearts ageing patterns. The primary endpoint included fatal and non-fatal CV events, and the secondary endpoint was a composite of CV and non-CV events and all-cause death. The heart phenotypic age (HeartPhAge) was estimated as a proxy of biological age. RESULTS: The slow ageing pattern was found in 8.7% of healthy participants, the normal pattern in 76.8%, and the accelerated pattern in 14.3%. Kaplan-Meier curves of the heart ageing patterns diverged significantly (P=0.0001) for both primary and secondary endpoints, with the event rate being lowest in the slow, intermediate in the normal, and highest in the accelerated pattern. In Cox proportional-hazards model, heart aging patterns predicted both primary (P=0.01) and secondary (P=0.03 to <0.0001) endpoints, independent of chronological age and risk factors. Compared to chronological age, HeartPhAge was 9 years younger in slow, 4 years older in accelerated (both P<0.0001), and overlapping in normal ageing patterns. CONCLUSION: Standard Doppler-echocardiography detects slow, normal, and accelerated heart ageing patterns. They predict CV and non-CV events, reflect biological age, and provide a new tool to calibrate prevention timing and intensity.

Age is the main risk factor for cardiovascular disease. Since people age and develop diseases at very different rates, biological age has been proposed as a more accurate measure of the body's functional decline. This study aimed to investigate the ageing rates of the heart and to assess their impact on cardiovascular events. The phenotypic age of the heart was also estimated as a proxy for biological age. Associations of age with Doppler echocardiographic parameters were analysed in a subgroup of 2614 clinically healthy subjects, part of a larger cohort of 3817 adults of both sexes. Three patterns of slow, normal, and accelerated ageing rates of the heart were detected. They predicted both cardiovascular and non-cardiovascular events, with different and progressively increasing event rates from the slow to the accelerated pattern. Compared to chronological age, the phenotypic (biological) age of the heart was 9 years younger in the slow pattern, 4 years older in the accelerated pattern, and comparable in the normal pattern. A standard Doppler echocardiogram is therefore able to detect three distinct heart ageing patterns, which reflect different biological susceptibilities to age-dependent diseases and provide a new tool for personalising timeliness and intensity of prevention.

Systematic basic and advanced resuscitation training in medical students and fellows: a proposal from the Working Group on Cardiovascular Urgences and Emergencies of the Italian Society of Cardiology.

Sudden cardiac arrest is a leading cause of death in Europe. High-quality cardiopulmonary resuscitation (CPR) and guidelines compliance of rescuers have been associated with better outcomes after cardiac arrest. However, wide variability in attempting bystander CPR manoeuvres has been reported. Educational programmes for teaching CPR to medical students and fellows are highly advisable in this context. However, there is no homogeneity regarding the CPR education offered by academic institutions. We surveyed 208 Italian medical students and 162 fellows in cardiology regarding the educational offer and needs in CPR. Among the 11 medical schools surveyed, 8 (73%) offer basic (BLS) courses but only 3 (38%) with formal certification of 'BLS provider', while none offers advanced (ACLS/ALS) courses. Among the 30 specialization schools in cardiology surveyed, 10 (33%) offer a BLS course (6 with formal certification of 'BLS provider'), and 8 (27%) offer an ACLS/ALS course (5 with formal certification). Only a minority of students and fellows perceive themselves as highly proficient either in BLS or ACLS/ALS, although most of the fellows were involved at least once in rescuing a cardiac arrest. The present position paper analyses and suggests the strategies that should be adopted by Italian medical and specialization schools to spread the CPR culture and increase the long-standing retention of CPR-related technical and nontechnical skills.

Celiac Disease and Cardiovascular Risk: A Retrospective Case-Control Study.

BACKGROUND: The association of celiac disease (CD) with premature atherosclerosis, including increased carotid artery intima-media thickness and cardiovascular disease (CVD), is controversial. The aim of this study was to investigate this relationship. METHODS: Clinical records of patients from Northern Sardinia referred to the Gastroenterology section of the Department of Medicine, University of Sassari, Italy, were analyzed. Unadjusted and adjusted odds ratios (ORs) for CVD with their 95% confidence intervals (CIs) were calculated according to established risk factors, including age, sex, diabetes, dyslipidemia, overweight/obesity, blood hypertension, and cigarette smoking, as well as a possible risk factor such as H. pylori infection. RESULTS: In a total of 8495 patients (mean age 52.1 ± 17.3 years; 64.7% females), 2504 reported a diagnosis of CVD and 632 of CD. Logistic regression analysis showed a significantly reduced risk of CVD among patients with CD (OR 0.30, 95% CI 0.22-0.41). Moreover, the long duration of the gluten-free diet (GFD) was able to lower the risk of CVD in celiac patients. Finally, CD significantly decreased the frequency of carotid plaques (11.8% vs. 40.1%, p < 0.001). CONCLUSIONS: Our retrospective study demonstrated that CD reduces the risk of CVD in general and more specifically of carotid lesions after adjusting for potential confounders, especially in those on GFD for a long time.

Increased Risk to Develop Hypertension and Carotid Plaques in Patients with Long-Lasting Helicobacter pylori Gastritis.

Helicobacter pylori infection has been reported to be positively associated with hypertension, although with conflicting results. In this study, the relationship between H. pylori infection and hypertension, as well as atherosclerotic carotid lesions, was analyzed. METHODS: Clinical records of patients referred to undergo upper endoscopy and gastric biopsy were retrieved. Information regarding the presence of H. pylori infection with atrophy/metaplasia/dysplasia (interpreted as a long-lasting infection), and current or past H. pylori infection was collected, as well as demographic variables, smoking habits, body mass index (BMI), dyslipidemia, diabetes, hypertension, presence of carotid lesions, and current treatment, and analyzed by multivariable regression models. RESULTS: A total of 7152 clinical records from patients older than 30 years (63.4% women) were available for the study. Hypertension was present in 2039 (28.5%) patients and the risk was significantly increased in those with long-lasting H. pylori infection after adjusting for age decades, sex, BMI, cigarette smoking, diabetes, and dyslipidemia (OR 1.17, 95% CI 1.02-1.35). In addition, the long-lasting H. pylori infection was an independent risk for carotid plaques (OR 2.15, 95% CI 1.14-4.09). CONCLUSIONS: Our retrospective study demonstrated that long-lasting H. pylori infection is an independent risk factor for hypertension and the presence of carotid lesions after adjusting for potential confounders, although further validation our findings is needed from prospective studies.

Not-high before-treatment platelet reactivity in patients with STEMI: prevalence, clinical characteristics, response to therapy and outcomes.

Platelet reactivity (PR) has been indicated as a pathophysiological key element for ST-Elevation Myocardial Infarction (STEMI) development. Patients with not-high before-treatment platelet reactivity (NHPR) have been poorly studied so far. The aim of this study is to investigate the prevalence, clinical characteristics, response to therapy and outcomes of baseline prior to treatment NHPR among patients with STEMI undergoing primary PCI.We analyzed the data from 358 STEMI patients with assessment of PR by VerifyNow before P2Y12 inhibitor loading dose (LD). Blood samples were obtained at baseline, and after 1 hour, 2 hours, 4-6 hours and 8-12 hours after LD. High platelet reactivity (HPR) was defined as Platelet Reactivity Unit values ≥208, while patients with values <208 at baseline were defined as having NHPR.Overall, 20% patients had NHPR. Age and male gender both resulted independent predictors of NHPR, even after propensity score adjustment. The percentage of inhibition of PR after ticagrelor or prasugrel LD was similar between HPR and NHPR patients at each time point. However, patients with HPR showed worse in-hospital clinical outcomes, and the composite adverse outcome endpoint of death, reinfarction, stroke, acute kidney injury or heart failure was significantly higher (10.0% vs 1.4%; p = .017) as compared with the NHPR group.In conclusion, a significant proportion of patients presenting with STEMI has a baseline NHPR that is associated with better in-hospital outcomes as compared with patients with HPR. Further studies are needed to better elucidate the potential therapeutic implications of NHPR in terms of secondary prevention.

Cardiac Abnormalities in Alzheimer Disease: Clinical Relevance Beyond Pathophysiological Rationale and Instrumental Findings?

OBJECTIVES: This case control study sought to assess the presence and characteristics of cardiac abnormalities in patients with Alzheimer disease (AD). BACKGROUND: Protein misfolding is involved in the pathophysiology of neurodegenerative disorders such as AD. Recently, amyloid-beta (Aß) aggregates were identified within the cardiomyocytes and interstitium of patients with AD, suggesting that Aß oligomers may reach and damage the heart. METHODS: The authors studied 32 patients with AD and 34 controls matched by age and sex, all of whom were free from cardiac or systemic diseases. A clinical evaluation, an electrocardiogram, and an echocardiogram were performed in all subjects. Furthermore, patients with AD underwent genetic analyses (of the PSEN1, PSEN2, APP, and APOE genes). RESULTS: Compared to the control group, patients with AD had a higher prevalence of low-voltage electrocardiographic QRS complexes (28% vs. 3%, respectively; p = 0.004), a lower voltage/mass ratio (p = 0.05), a greater echocardiographic interventricular septum (10.1 ± 1.3 mm vs. 9.3 ± 1.1 mm, respectively; p = 0.01), a greater maximum wall thickness (10.8 ± 1.7 mm vs. 9.3 ± 1.1 mm, respectively; p = 0.0001), and a 2-fold higher prevalence of diastolic dysfunction (70% vs. 35%, respectively; p = 0.007). Symptoms and signs of heart failure were absent in all patients with AD. CONCLUSIONS: This study shows that electrocardiographic and echocardiographic abnormalities, including diastolic dysfunction, are present in patients with AD and that these studies reproduce the pattern of cardiac amyloidosis. These findings suggest that, in AD, there may be subclinical cardiac involvement likely associated with Aß amyloid deposition. The clinical relevance of these cardiac abnormalities should be evaluated in larger prospective studies.

Prevalence and Determinants of Peripheral Microvascular Endothelial Dysfunction in Rheumatoid Arthritis Patients: A Multicenter Cross-Sectional Study.

OBJECTIVES: To define the prevalence and determinants of peripheral microvascular endothelial dysfunction (ED) in a large series of rheumatoid arthritis (RA) patients free of previous cardiovascular events. MATERIALS AND METHODS: Data from 874 RA patients enrolled in the EDRA study (Endothelial Dysfunction Evaluation for Coronary Heart Disease Risk Estimation in Rheumatoid Arthritis-ClinicalTrials.gov: NCT02341066) were analyzed. Log-transformed reactive hyperemia index (Ln-RHI) was evaluated by peripheral arterial tonometry (PAT) using the EndoPAT2000 device: values of Ln-RHI < 0.51 were considered indicative of peripheral ED. RESULTS: Peripheral microvascular ED was documented in one-third of RA patients (33.5%); in multiple logistic regression analysis, ACPA negativity and higher triglycerides concentrations were independently associated with the presence of peripheral ED [OR (95% CI) = 1.708 (1.218-2.396), p < 0.01 and OR (95% CI) = 1.005 (1.002-1.009), p < 0.01, respectively]. Multiple regression analysis showed a positive correlation between Ln-RHI values and systolic blood pressure and HDL cholesterol levels; furthermore, higher values of Ln-RHI were associated with ACPA positivity, while smoking habit was associated with lower Ln-RHI values. CONCLUSIONS: This study demonstrates for the first time a high prevalence of peripheral microvascular ED in patients with RA free of previous cardiovascular events that appear to be only partially driven by traditional cardiovascular risk factors. The association between ACPA negativity and ED warrants further exploration.

Asymmetric dimethylarginine and arterial stiffness in patients with rheumatoid arthritis: A case-control study.

OBJECTIVE: To investigate whether levels of asymmetric dimethylarginine (ADMA), as a measure of endothelial dysfunction, are higher in patients with rheumatoid arthritis compared with healthy control subjects. The relationships between ADMA and surrogate measures of arterial stiffness were evaluated. METHODS: Patients with rheumatoid arthritis and healthy control subjects were recruited. ADMA was quantified via enzyme-linked immunosorbent assay. Arterial stiffness was evaluated using pulse wave analysis. RESULTS: There was no significant difference in plasma ADMA concentration between patients with rheumatoid arthritis (n = 30) and healthy controls (n = 30). Aortic augmentation pressure was significantly higher in patients than in controls. C-reactive protein and Health Assessment Questionnaire score were independent predictors of arterial stiffness in patients. There was no relationship between ADMA concentration and aortic augmentation pressure in the study population as a whole. CONCLUSIONS: Arterial stiffness appears to be increased in rheumatoid arthritis and independently associated with systemic inflammation and physical disability. ADMA concentration was not increased in this small group of patients with rheumatoid arthritis compared with healthy controls; nor was it associated with arterial stiffness.

Left ventricular diastolic function in hypertension: methodological considerations and clinical implications.

The assessment of left ventricular (LV) diastolic function should be an integral part of a routine examination of hypertensive patient; indeed when LV diastolic function is impaired, it is possible to have heart failure even with preserved LV ejection fraction. Left ventricular diastolic dysfunction (LVDD) occurs frequently and is associated to heart disease. Doppler echocardiography is the best tool for early LVDD diagnosis. Hypertension affects LV relaxation and when left ventricular hypertrophy (LVH) occurs, it decreases compliance too, so it is important to calculate Doppler echocardiography parameters, for diastolic function evaluation, in all hypertensive patients. The purpose of our review was to discuss about the strong relationship between LVDD and hypertension, and their relationship with LV systolic function. Furthermore, we aimed to assess the relationship between the arterial stiffness and LV structure and function in hypertensive patients.

An update on hypertensive emergencies and urgencies.

Severe acute arterial hypertension is usually defined as 'hypertensive crisis', although 'hypertensive emergencies' or 'hypertensive urgencies', as suggested by the Joint National Committee and the European Society of Hypertension, have completely different diagnostic and therapeutic approaches.The prevalence and demographics of hypertensive emergencies and urgencies have changed over the last four decades, but hypertensive emergencies and urgencies are still associated with significant morbidity and mortality.Different scientific societies have repeatedly produced up-to-date guidelines; however, the treatment of hypertensive emergencies and urgencies is still inappropriate, with potential clinical implications.This review focuses on hypertensive emergencies and urgencies management and treatment, as suggested by recent data.

Serum free thyroxine levels are positively associated with arterial stiffness in the SardiNIA study.

OBJECTIVE: Thyroid dysfunction may accelerate atherosclerosis. Aortic pulse wave velocity (PWV) is an early index of arterial stiffness and an important risk factor for cardiovascular disease and might therefore be linked to changes in thyroid activity. We investigated the relationship between thyroid function and carotid-femoral PWV, as an index of arterial stiffness. DESIGN: Cross-sectional cohort study. PATIENTS: Participants from the SardiNIA study. Those being treated for thyroid diseases were excluded, yielding a sample of 5875 aged 14-102. MEASUREMENTS: Clinical parameters, blood tests including serum TSH and serum FT4, and carotid-femoral PWV were measured. RESULTS: After adjusting for confounders, a direct and linear association between FT4 and PWV was shown (multiple regression analysis). The model containing age, mean blood pressure, body mass index, heart rate, FT4, hypertension, diabetes and dyslipidaemia accounted for 55% of the variation in PWV. CONCLUSIONS: Like several other known risk factors, serum FT4 levels are associated with carotid-femoral PWV, suggesting that high FT4 levels have a detrimental effect on aortic stiffness and may contribute to ageing process of the vascular system. This finding may help to understand the pathogenesis of cardiovascular disease and contribute to improve prevention therapy.

Cardiovascular health in migrants: current status and issues for prevention. A collaborative multidisciplinary task force report.

OBJECTIVES: To review information on cardiovascular health and migration, to stress the attention of researchers that much needs to be done in the collection of sound data in Italy and to allow policy makers identifying this issue as an important public health concern. BACKGROUND: In Italy, the rate of immigrants in the total number of residents increased from 2.5% in 1990 to 7.4% in 2010, and currently exceeds 10% in regions such as Lombardia, Emilia Romagna and Toscana. METHODS: A consensus statement was developed by approaching relevant Italian national scientific societies involved in cardiovascular prevention. Task force members were identified by the president and/or the boards of each relevant scientific society or working group, as appropriate. To obtain a widespread consensus, drafts were merged and distributed to the scientific societies for local evaluation and revision by as many experts as possible. The ensuing final draft was finally approved by scientific societies. RESULTS: In several western European countries, the prevalence of hypertension, diabetes, chronic kidney disease, obesity and metabolic syndrome was found to be higher among immigrants than in the native population. Although migrants are often initially healthier than non-migrant populations in their host countries, genetic factors, and changing environments with lifestyle changes, social exclusion and insufficient medical control may expose them to health challenges. Cultural reasons may also hamper both the dissemination of prevention strategies and migrant communication with healthcare providers. However, great diversity exists across and within different groups of migrants, making generalizations very difficult and many countries do not collect registry or survey data for migrant's health. CONCLUSIONS: In the present economic context, the European Union is placing great attention to improve data collection for migrant health and to support the implementation of specific prevention policies aimed at limiting the future burden of cardiovascular and renal disease, and the consequent load for health systems. Wider initiatives on the topic are awaited in Italy.
