Prevalence, Clustering, and Current Management of Cardiovascular Risk Factors Upon First Referral to Hypertension Specialists: the APPROACH Study.

INTRODUCTION: Several observational studies have been conducted to assess the prevalence of cardiovascular risk factors in hypertensive patients; however, none has yet investigated prevalence, clustering, and current management of cardiovascular risk factors upon first referral to hypertension specialists, which is the aim of the present study. METHODS: Consecutive adult outpatients with essential/secondary hypertension were included at the time of their first referral to hypertension specialists at 13 Italian centers in the period April 2022-2023 if they had at least one additional major cardiovascular risk factor among LDL-hypercholesterolemia, type 2 diabetes, and cigarette smoking. Prevalence, degree of control, and current management strategies of cardiovascular risk factors were assessed. RESULTS: A total of 255 individuals were included, 40.2% women and 98.4% Caucasian. Mean age was 60.3±13.3 years and mean blood pressure [BP] was 140.3±17.9/84.8±12.3 mmHg). Most participants were smokers (55.3%), had a sedentary lifestyle (75.7%), suffered from overweight/obesity (51%) or high LDL-cholesterol (41.6%), had never adopted strategies to lose weight (55.7%), and were not on a low-salt diet (57.4%). Only a minority of patients reported receiving specialist counseling, and 27.9% had never received recommendations to correct unhealthy lifestyle habits. Nearly 90% of individuals with an estimated high/very high cardiovascular risk profile did not achieve recommended LDL-cholesterol targets. CONCLUSIONS: In patients with hypertension, both pharmacological and lifestyle therapeutic advice are yet to improve before referral to hypertension specialists. This should be considered in the primary care setting in order to optimize cardiovascular risk management strategies.

Baseline cardio-oncologic risk assessment in breast cancer women and occurrence of cardiovascular events: The HFA/ICOS risk tool in real-world practice.

BACKGROUND: the European Society of Cardiology Heart Failure Association (HFA) together with the International Cardio-Oncology Society (ICOS) proposed charts for baseline CV risk assessment of cancer patients scheduled to receive anthracyclines and anti-human epidermal growth factor receptor-2 (HER2) agents. METHODS: We investigated HFA/ICOS risk stratification, prescriptions of cardioactive drugs, and occurrence of CV events in a multicentric breast cancer (BC) cohort from 3 Italian Outpatient Cardio-Oncology Clinics. RESULTS: 373 BC patients who underwent a baseline Cardio-Oncologic evaluation were included, of whom 202 scheduled to receive anthracyclines and 171 anti-HER2. Mean age was 60 ± 12 years and 49% of BC patients had ≥2 CV risk factors. In the anthracyclines group, 51% were at low-risk, 43% at medium-risk and 6% at high-risk; while in the anti-HER2 group, 27% patients were at low-risk, 58% at medium-risk and 15% at high-risk. In both groups, a medium-to-high risk was associated with use of cardioactive therapies (p < 0.0001). There were no LVD events in anthracycline recipients, and 16 LVD among anti-HER2 patients. A medium-to-high risk was not associated with LVD occurrence (p = 0.17). CONCLUSIONS: Patients with medium-to-high HFA/ICOS risk were more likely to receive cardioactive therapies, possibly explaining the lack of association of risk categories with LVD occurrence.

Could maternal ethnicity be a determinant of healthcare costs for birth assistance? Insights from a retrospective hospital-based study for the implementation of a woman-centered approach in obstetrics.

BACKGROUND: Current policy and service provision recommend a woman-centered approach to maternity care and the development of personalized models for clinical assistance. Ethnicity has been recognized as a determinant in the risk calculation of selected obstetric complications. Based on these assumptions, our aims were to describe the linkage between baseline characteristics and maternal ethnicity and to analyze the cost for the local healthcare system, distinguishing mode of delivery, absence or presence of complications at birth, and maternal stay duration for all ethnic groups. METHODS: In a 5-year period (2012-16), all women admitted for delivery at the Department of Obstetrics and Gynecology, Fondazione Policlinico Universitario "A Gemelli" IRCCS, Rome, Italy, were included in the analysis. Maternal demographics, adverse outcomes, and costs were evaluated. Economic calculations were performed by using the "diagnosis-related group" (DRG) approach. RESULTS: A total of 18,093 patients were included in the analysis. An overall care expense of €42,663,481 was calculated. Caucasian was the main ethnicity (90.7%), with 9.3% minority groups. Vaginal delivery (VD) was the most common mode of delivery in all ethnic groups, with a global rate of 59.6%. The highest cesarean section (CS) rates were observed among Maghreb (51.5%) and Afro-Caribbean (47.8%) women. Minority groups had a doubled rate of complicated VD, primarily Afro-Caribbean women (69.9%), followed by Asian (64.1%), Maghreb (63.2%), and Latin American (62.7%) women. Afro-Caribbean women had the highest rate of complicated CS compared to the overall study population (37.6 versus 28.5%, p < .005). CONCLUSIONS: Minority groups have increased healthcare costs for birth assistance, mainly due to the higher rates of complications. In a prospective view, two strategies could be planned: first, calculating individualized risk to mitigate the clinical care charge, based on the ad hoc combination of ethnicity, mode of delivery, and obstetric complications; and second, endorsing the current financial return-on-investment opportunity tied to mitigating ethnic disparities in birth outcomes.

Identification of a plausible serum uric acid cut-off value as prognostic marker of stroke: the Uric Acid Right for Heart Health (URRAH) study.

The Working Group on Uric Acid and Cardiovascular Risk of the Italian Society of Hypertension conceived and designed an ad hoc study aimed at searching for prognostic cut-off values of serum uric acid (SUA) in predicting combined (fatal and non-fatal) cerebrovascular (CBV) events in the whole database. The URic acid Right for heArt Health study is a nationwide, multicenter, observational cohort study involving data on subjects aged 18-95 years recruited on a regional community basis from all the territory of Italy under the patronage of the Italian Society of Hypertension with a mean follow-up period of 120.7 ± 61.8 months. A total of 14,588 subjects were included in the analysis. A prognostic cut-off value of SUA able to discriminate combined CBV events (>4.79 mg/dL or >284.91 µmol/L) was identified by means of receiver operating characteristic curve in the whole database. Multivariate Cox regression analysis adjusted for confounders (age, sex, arterial hypertension, diabetes, chronic kidney disease, smoking habit, ethanol intake, body mass index, low-density lipoprotein cholesterol, and use of diuretics) identified an independent association between SUA and combined CBV events in the whole database (HR 1.249, 95% confidence interval, 1.041-1.497, p = 0.016). The results of the present study confirm that SUA is an independent risk marker for CBV events after adjusting for potential confounding variables, including arterial hypertension, and demonstrate that >4.79 mg/dL is a valid prognostic cut-off value.

Coronavirus disease 2019 in patients with cardiovascular disease: clinical features and implications on cardiac biomarkers assessment.

INTRODUCTION: Previous cardiovascular disease (CVD) and myocardial involvement are common in coronavirus disease-19 (COVID-19). We investigated relationships between CVD, cardiac biomarkers and outcome in COVID-19. METHODS: We analyzed n = 252 patients from a multicenter study and provided comparison according to the presence or absence of underlying CVD. Cardiac biomarkers high-sensitivity Troponin [upper reference of normality (URN) 35 pg/ml for Troponin I and 14 pg/ml for Troponin T] and natriuretic peptides (Nt-pro-B-type natriuretic peptide, URN 300 pg/ml and B-type natriuretic peptide, URN 100 pg/ml) were both available in n = 136. RESULTS: Mean age was 69 ±â€Š16 years (56% men, 31% with previous CVD). Raised hs-Troponin and natriuretic peptides were detected in 36 and 50% of the cases respectively. Age, chronic obstructive pulmonary disease, hemoglobin, hs-Troponin and natriuretic peptides were independently associated with underlying CVD (P < 0.05 for all). Compared with the normal biomarkers subgroups, patients with isolated hs-Troponin elevation had higher in-hospital mortality (31 vs. 4%, P < 0.05), similar CVD prevalence (15 vs. 11%) and trend towards higher D-dimer (930 vs. 397 ng/ml, P = 0.140). Patients with both biomarkers elevated had higher age, D-dimer, CVD and in-hospital mortality prevalence compared with other subgroups (all P < 0.05 for trend). Outcome analysis revealed previous CVD [model 1: OR 2.72 (95% CI 1.14-6.49), P = 0.024. model 2: OR 2.65 (95% CI 1.05-6.71), P = 0.039], hs-Troponin (log10) [OR 2.61 (95% CI 1.21-5.66), P = 0.015] and natriuretic peptides (log10) [OR 5.84 (95%CI 2.43-14), P < 0.001] to be independently associated with in-hospital mortality. CONCLUSION: In our population, previous CVD was part of a vulnerable phenotype including older age, comorbidities, increased cardiac biomarkers and worse prognosis. Patients with isolated increase in hs-Troponin suffered higher mortality rates despite low prevalence of CVD, possibly explained by higher COVID-19-related systemic involvement.

Cost analysis for deliveries according to maternal age classes for moving to a personalized approach in the health care.

Objective: In the last decades, childbearing has moved to higher ages, displaying adverse outcomes related to advanced maternal age at birth. Accordingly, the aim was to perform a cost analysis in women admitted for birth assistance and segregated by age classes (<20, 20-24, 25-29, 30-34, 35-39, 40-45, and ≥45 years).Methods: A total of 18,093 admitted for assistance at delivery in a 5-year period (2012-2016) were included in the analysis. Costs for obstetric complications in vaginal delivery (VD) and cesarean section (CS), based on hospital discharge report from the local health care system, were calculated by using the "diagnosis-related group" (DRG) approach.Results: An overall economic cost due to clinical assistance at delivery of €42.663.481 was computed. A global rate of 59.6% of vaginal deliveries (VD) and 40.4% of cesarean section (CS) was assessed. Among of all maternal age classes, women attributable to classes 30-34 and 35-39 years reached a rate of 62.8%, while values of 24.2 and 13% were observed for those under 30 and over 40 years of age, respectively. A significant increasing trend in terms of maternal stay duration was found across all age groups (from 4.7 to 5.4 days, p < .05), as well as nonspecific delivery costs (from €2.222.49 to €2.401.29, p < .05). Uncomplicated VD decreased across the groups, until to halve between two extreme maternal age groups (38.8 versus 18.6%, p < .05), while a three-fold risk of CS complications was calculated in women over 45 years-old in comparison with those under 20 years of age (4.2 versus 13.9, p < .05), although not significantly different in the cost analysis between two extreme age groups.Conclusions: Increases in maternal age at delivery are associated with higher healthcare costs, driven largely by additional complication rates, irrespective of the delivery mode.

Serum uric acid, predicts heart failure in a large Italian cohort: search for a cut-off value the URic acid Right for heArt Health study.

OBJECTIVE: To assess the prognostic cut-off values of serum uric acid (SUA) in predicting fatal and morbid heart failure in a large Italian cohort in the frame of the Working Group on Uric Acid and Cardiovascular Risk of the Italian Society of Hypertension. METHODS: The URic acid Right for heArt Health (URRAH) study is a nationwide, multicentre, cohort study involving data on individuals aged 18-95 years, recruited on a community basis from all regions of Italy under the patronage of the Italian Society of Hypertension with a mean follow-up period of 128 ±â€Š65 months. Incident heart failure was defined on the basis of International Classification of Diseases Tenth Revision codes and double-checked with general practitioners and hospital files. Multivariate Cox regression models having fatal and morbid heart failure as dependent variables, adjusted for sex, age, SBP, diabetes, estimated glomerular filtration rate, smoking habit, ethanol intake, BMI, haematocrit, LDL cholesterol, previous diagnosis of heart failure and use of diuretics as possible confounders, were used to search for an association between SUA as a continuous variable and heart failure. By means of receiver operating characteristic curves, two prognostic cut-off values (one for all heart failure and one for fatal heart failure) were identified as able to discriminate between individuals doomed to develop the event. These cut-off values were used as independent predictors to divide individuals according to prognostic cut-off values in a multivariate Cox models, adjusted for confounders. RESULTS: A total of 21 386 individuals were included in the analysis. In Cox analyses, SUA as a continuous variable was a significant predictor of all [hazard ratio 1.29 (1.23-1.359), P < 0.0001] and fatal [hazard ratio 1.268 (1.121-1.35), P < 0.0001] incident heart failure. Cut-off values of SUA able to discriminate all and fatal heart failure status were identified by mean of receiver operating characteristic curves in the whole database: SUA more than 5.34 mg/dl (confidence interval 4.37-5.6, sensitivity 52.32, specificity 63.96, P < 0.0001) was the univariate prognostic cut-off value for all heart failure, whereas SUA more than 4.89 mg/dl (confidence interval 4.78-5.78, sensitivity 68.29, specificity 49.11, P < 0.0001) for fatal heart failure. The cut-off for all heart failure and the cut-off value for fatal heart failure were accepted as independent predictors in the Cox analysis models, the hazard ratios being 1.645 (1.284-2.109, P < 0.0001) for all heart failure and 1.645 (1.284-2.109, P < 0.0001) for fatal heart failure, respectively. CONCLUSION: The results of the current study confirm that SUA is an independent risk factor for all heart failure and fatal heart failure, after adjusting for potential confounding variables and demonstrate that a prognostic cut-off value can be identified for all heart failure (>5.34 mg/dl) and for fatal heart failure (>4.89 mg/dl).

The emotional and social burden of heart failure: integrating physicians', patients', and caregivers' perspectives through narrative medicine.

BACKGROUND: The The Roadmap Using Story Telling project used a narrative medicine (NM) framework to assess the perspectives of people with heart failure (HF), their informal caregivers and HF specialists of the impact of HF on the daily life of patients and their carers. METHODS: Italian HF specialists participated on a voluntary basis, completing their own narratives, and inviting patients and their caregivers to write anonymously about their experiences, all on a dedicated online platform. The narratives were analyzed according to standard NM methodology. RESULTS: 82 narratives were collected from patients, 61 from caregivers, and 104 from HF specialists. Analysis of the three points of view revealed the extent of the burden of illness on the entire family, particularly that of the caregiver. The impact was mainly experienced as emotional and social limitations in patients' and their caregivers' daily lives. The analysis of all three points of view highlighted a strong difference between how HF is perceived by patients, caregivers, and HF specialists. CONCLUSIONS: This NM project illustrates the complex issues of living with HF and gave insights to integrate three different perspectives into the HF pathway of care.

Functional Role of Natriuretic Peptides in Risk Assessment and Prognosis of Patients with Mitral Regurgitation.

The management of mitral valve regurgitation (MR), a common valve disease, represents a challenge in clinical practice, since the indication for either surgical or percutaneous valve replacement or repair are guided by symptoms and by echocardiographic parameters which are not always feasible. In this complex scenario, the use of natriuretic peptide (NP) levels would serve as an additive diagnostic and prognostic tool. These biomarkers contribute to monitoring the progression of the valve disease, even before the development of hemodynamic consequences in a preclinical stage of myocardial damage. They may contribute to more accurate risk stratification by identifying patients who are more likely to experience death from cardiovascular causes, heart failure, and cardiac hospitalizations, thus requiring surgical management rather than a conservative approach. This article provides a comprehensive overview of the available evidence on the role of NPs in the management, risk evaluation, and prognostic assessment of patients with MR both before and after surgical or percutaneous valve repair. Despite largely positive evidence, a series of controversial findings exist on this relevant topic. Recent clinical trials failed to assess the role of NPs following the interventional procedure. Future larger studies are required to enable the introduction of NP levels into the guidelines for the management of MR.

Immigration Emergency in Italy: The Impact of Socioeconomic Status on Blood Pressure Levels and Control.

INTRODUCTION: Nowadays there are more than 5 millions of immigrants (8.3% of general adult population) in Italy. AIM: To evaluate the potential impact of immigration and the possession of a permanent residence on blood pressure (BP) levels and control in a low income population of immigrants from different countries. METHODS: We evaluated clinical characteristics and social status of adult individuals with known diagnosis of hypertension afferent to the Poliambulatorio della Caritas Diocesana in Rome, Italy, between 2010-2016. Subjects were stratified according to their macro-areas of origin (Europe, Asia, Africa, South-America), housing (with or without house), and immigration status (presence or absence of residence permit). BP levels were measured in three consecutive visits according to recommendations from current European Guidelines. RESULTS: From an overall population sample of 9827 adult individuals, we initially identified 994 patients with a diagnosis of hypertension (10.1%), among whom 536 (5.4%) had valid BP data. Among these, 50.6% came from Europe, 21.6% from Africa, 24.1% from Asia, and 3.7% from South-America. They were predominantly male (54.7%), middle aged (42.8 ± 12.1 years at arrival and 51.6 ± 10.6 years at first visit) and untreated (72.8%) individuals with baseline systolic/diastolic BP levels of 156.9 ± 22.2/97.3 ± 12.4 mmHg). BP levels remained higher in homeless than in housed people at both visit 2 (150.0 ± 21.8/92.6 ± 12.9 mmHg vs. 142.9 ± 19.3/89.9 ± 11.6 mmHg; P < 0.001) and visit 3 (147.9 ± 22.2/91.7 ± 12.5 mmHg vs. 141.8 ± 19.4/89.2 ± 12.0 mmHg; P = 0.013). We also observed reductions of both systolic and diastolic BP levels compared to baseline values in immigrants stratified according to residence permit, although without relevant differences among groups. CONCLUSIONS: Beyond conventional risk factors, socio-economic issues, including lack of residence permit or habitation, may affect BP levels and control in frail populations of immigrants, which have been marginally considered before.

Conventional and new electrocardiographic criteria for hypertension-mediated cardiac organ damage: A narrative review.

Hypertension-mediated organ damage (HMOD) is frequently observed in hypertensive patients at different cardiovascular (CV) risk profile. This may have both diagnostic and therapeutic implications for the choice of the most appropriate therapies. Among different markers of HMOD, the most frequent functional and structural adaptations can be observed at cardiac level, including left ventricular hypertrophy (LVH), diastolic dysfunction, aortic root dilatation, and left atrial enlargement. In particular, LVH was shown to be a strong and independent risk factor for major CV events, namely myocardial infarction, stroke, congestive heart failure, CV death. Thus, early identification of LVH is a key element for preventing CV events in hypertension. Although echocardiographic assessment of LVH represents the gold standard technique, this is not cost-effective and cannot be adopted in routine clinical practice of hypertension. On the other hand, electrocardiographic (ECG) assessment of HMOD relative to the heart is a simple, reproducible, widely available and cost-effective method to assess the presence of LVH, and could be preferred in large scale screening tests. Several new indicators have been proposed and tested in observational studies and clinical trials of hypertension, in order to improve the relatively low sensitivity of the conventional ECG criteria for LVH, despite high specificity. This article reviews the differences in the use of the main conventional and the new 12 lead ECG criteria of LVH for early assessment of asymptomatic, subclinical cardiac HMOD in a setting of clinical practice of hypertension.

Quantification of nursing care and creation of economic indicators: an observational study protocol.

BACKGROUND: The literature on hospital admissions costs shows that classification of hospitalization systems such as the DRG system used in Italy, do not reflect the real cost of the production factors used, including those of nursing care in relation to the complexity of the hospital effort. OBJECTIVE: This concept paper outlines the study protocol and the methodology used to measure nursing care in economic terms. The objective of the study is developed on the assumption of creating economic indicators from a quantitative analysis of nursing activities provided to specific patients, in order to determine not only who costs but also the reasons for the cost, and demonstrate the variability of nursing not only for DRG, but also each individual patient. METHODS: A retrospective study and a longitudinal prospective study will be performed. In the first phase of the study, using a bottom-up Microcosting methodology the type, volume, time and costs of nursing activities for DRG will be determined and the incidence of nursing costs on reimbursement will be highlighted.In the second phase, the above analysis will be supplemented by the recognition of the complexity of individual cases measured through the Corridor Triage(Tri-CO), in order to figure out the incidence of costs of nursing activities on the reimbursement in relation to the level of care complexity. Main sources of data: hospital discharge card (SDO); Professional Assessment Instrument (PAI); datasets for collecting the time of delivery of nursing activities on PAI. Power calculation: For retrospective study, the survey will be conducted on a sample of 150 patients hospitalized in the first quarter of 2016. For the longitudinal prospective study, 150 patients will be included in the first quarter of 2017 after the structured introduction of Tri-CO as a valuation tool of care complexity. The sample examined is approximately 30% of the total number of admissions per year. RESULTS: The study started in February 2016 and the results are expected for May 2017. Through this study it is expected to verify whether by implementing a unbundling approach, ie the "unpacking" of the production factors (nursing activity costs) used for the explication of hospitalization, and by adopting a methodology based on standard analytical costs, a more detailed knowledge of the overall DRG rate data available today will be obtained, which is currently lacking of explicit notation of all the amounts that make up it.

Adding markers of organ damage to risk score models improves cardiovascular risk assessment: Prospective analysis of a large cohort of adult outpatients.

INTRODUCTION: Global cardiovascular (CV) risk stratification is recommended in all outpatients. Risk score charts, however, do not include markers of organ damage (OD). AIM: To evaluate the potential added value of including different markers of subclinical OD to US Framingham, European SCORE and Italian Cuore risk score calculators. METHODS: We prospectively evaluated adult outpatients, who underwent blood pressure (BP) assessment and global CV risk stratification. The following OD markers were considered: 1) cardiac OD: electrocardiographic) or echocardiographic left ventricular (LV) hypertrophy; 2) vascular OD: carotid atherosclerotic plaque; 3) renal OD: reduced estimated glomerular filtration rate or creatinine clearance. Different risk score calculators were applied for comparisons. RESULTS: We included an overall population sample of 1979 outpatients (44.0% female, age 57.2±13.0years, BMI 26,6±4,4kg/m2, clinic systolic/diastolic BP 145.4±18.3/85.8±10.7mmHg), among whom 117 (5.9%) presented cardiac, 161 (8.1%) vascular, and 117 (5.9%) renal OD. US Framingham, European SCORE and Italian Cuore risk scores were all significantly raised in patients with than in those without OD. A trend toward increase for US Framingham CVD death, European ESC and Italian Cuore scores was observed according to degree of all markers of OD. Among these, reduced ClCr and eGFR showed high sensitivity and specificity to identify high risk individuals. CONCLUSIONS: Presence of cardiac, vascular or renal OD is associated with higher risk scores, independently by the types of calculators, age and gender classes. OD detection should be included in CV risk stratification in order to improve diagnostic, prognostic and therapeutic processes.

Hypertension in Young People: Epidemiology, Diagnostic Assessment and Therapeutic Approach.

High blood pressure (BP) still remains one of the most relevant cardiovascular risk factors, also due to its persistently high prevalence and growing incidence in the general adult and elderly population. Since almost all hypertension-related cardiovascular complications, mostly including coronary artery disease, myocardial infarction, ischemic stroke, and congestive heart failure, occurred in adult and elderly individuals, evidence on both prevalence and clinical management of hypertension in young individuals are lacking. Therefore, the clinical impact of high BP levels in young populations remains to be explored. In the recent years, the attitude of the scientific community has changed and more attention was devoted to young individuals with hypertension, also in view of the fact that early identification of these subjects may prevent developing of established hypertension in adulthood. In addition, unhealthy lifestyle habits have progressively involved children and adolescents worldwide, thus contributing to further increase the risk of developing hypertension in young individuals. On the basis of these considerations, the present review is aimed at providing a brief reappraisal of the major aspects of hypertension in the young age, as well as at promoting interest and discussion on this important issue.

Integrated preclinical cardiovascular prevention: a new paradigm to face growing challenges of cardiovascular disease.

Cardiovascular disease (CVD) still represents the leading cause of mortality and morbidity worldwide. Despite considerable improvements in the prognosis of CVD and the significant reduction of CVD mortality obtained during the past half century, patients developing CVD, even though satisfactorily treated, still carry coronary artery disease and remain at risk for advanced CVD. Thus, the healthcare and socioeconomic burden linked to CVD remains high. As a result, more effective CVD prevention strategies remain crucial. 'Population strategies' and 'high-risk' approaches both have limitations and have often been viewed as alternative solutions. This persistent dualism could be overcome with the promotion of integrated prevention strategies based on a systematic evaluation of the total risk of disease, at both a population and an individual level. New approaches are also needed to reach people earlier in the course of the vascular disease and, possibly, to prevent risk factors and reduce CVD clinical manifestation.

An easy and reproducible parameter for the assessment of the pressure gradient in patients with aortic stenosis disease: A magnetic resonance study.

AIM: Cardiovascular magnetic resonance (CMR) has been increasingly used as an alternative method to evaluate the severity of aortic stenosis. The aim of our study was to evaluate whether the indirect measurement of the aortic gradient (Calc-PG), derived from Gorlin's formula, is a reproducible parameter for gradient assessment. Then, we evaluated if this parameter is correlated with left ventricular hypertrophy, considered as a marker of severity of aortic stenosis, better than phase-contrast sequences-derived pressure gradient (PC-PG) and aortic valve area. METHODS: Forty-one patients with isolated aortic stenosis underwent CMR. Calc-PG was obtained from the formula (cardiac output/aortic valve area)(2), and it was compared to PC-PG. RESULTS: We found that the Calc-PG has higher correlation with left ventricle mass than PC-PG (r(2) 0.44, p<0.001 vs. r(2) 0.26, p<0.01), also after multivariate analysis adjusting for age, gender and hypertension (p<0.001). Furthermore, Calc-PG was more reproducible than PC-PG. The receiver operating characteristic comparison curve analysis showed that Calc-PG has a significantly higher ability to describe the presence of left ventricular hypertrophy than PC-PG (area under the curve 0.85, 95% CI 0.70-0.94, p<0.0001 vs. 0.74, 95% CI 0.58-0.87, p=0.03). CONCLUSIONS: We propose that transaortic gradient indirectly calculated by using the simplified Gorlin's equation could be an alternative method to assess the severity of aortic stenosis.

Polypharmacy in heart failure patients.

In heart failure (HF), the progressive use of multiple drugs and a complex therapeutic regimen is common and is recommended by international guidelines. With HF being a common disease in the elderly, patients often have numerous comorbidities that require additional specific treatment, thus producing a heavy pill burden. Polypharmacy, defined as the chronic use of five or more medications, is an underestimated problem in the management of HF patients. However, polypharmacy has an important impact on HF treatment, as it often leads to inappropriate drug prescription, poor adherence to pharmacological therapies, drug-drug interactions, and adverse effects. The growing complexity of HF patients, whose mean age increases progressively and who present multiple comorbidities, suggests the need for newer models of primary care to improve the management of HF patients. Self-care, telemonitoring, and natriuretic peptide-guided therapy represent promising new HF care models to face the complexity of the disease and its therapeutic regimen.
