RESUMO

Background: Patients with chronic diseases such as heart failure (HF) are at risk of hospital admission. We evaluated the impact of living in nursing homes (NH) on readmissions and all-cause mortality of HF patients during a one-year follow up. Methods: An observational and multicenter study from the Spanish National Registry of Heart Failure (RICA) was performed. We compared clinical and prognostic characteristics between both groups. Bivariate analyses were performed using Student's t-test and Tukey's method and a Kaplan–Meier survival at one-year follow up. A multivariate proportional hazards analysis of [Cox] regression by the conditional backward method was conducted for the variables being statistically significant related to the probability of death in the univariate. Results: There were 5644 patients included, 462 (8.2%) of whom were nursing home residents. There were 52.7% women and mean age was 79.7±8.8 years. NH residents had lower Barthel (74.07), Charlson (3.27), and Pfeiffer index (2.2), p<0.001). Mean pro-BNP was 6686pg/ml without statistical significance differences between groups. After 1-year follow-up, crude analysis showed no differences in readmissions 74.7% vs. 72.3%, p=0.292, or mortality 63.9% vs. 61.1%, p=0.239 between groups. However, after controlling for confounding variables, NH residents had a higher 1-year all-cause mortality (HR 1.153; 95% CI 1.011–1.317; p=0.034). Kaplan–Meier analysis showed worse survival in nursing home residents (log-rank of 7.12, p=0.008). Conclusions: Nursing home residents with heart failure showed higher one-year mortality which could be due to worse functional status, higher comorbidity, and cognitive deterioration.(AU)


Introducción: Los pacientes con enfermedades crónicas como la insuficiencia cardiaca (IC) presentan mayor riesgo de ingreso. Se evaluó el impacto sobre los reingresos y la mortalidad por todas las causas de los pacientes con IC respecto a vivir o no en residencias de ancianos durante un año de seguimiento. Métodos: Estudio observacional y multicéntrico a partir del Registro Nacional de Insuficiencia Cardiaca (RICA). Se compararon las características clínicas y pronósticas entre ambos grupos. Se realizó un análisis bivariante mediante el método de t de Student y Tukey y un análisis de supervivencia mediante Kaplan-Meier al año de seguimiento, así como un análisis multivariante de riesgos proporcionales de regresión (Cox) por el método de retroceso condicional para las variables que se relacionaban de forma estadísticamente significativa con la probabilidad de muerte en el univariante. Resultados: Fueron incluidos 5.644 pacientes; 462 (8,2%) de ellos estaban en residencias, el 52,7% eran mujeres y la edad media era de 79,7±8,8 años. Los pacientes en residencias tenían menor Barthel (74,07), Charlson (3,27) y Pfeiffer (2,2) (p<0,001). El pro-BNP medio era de 6.686 pg/ml sin diferencias significativas. Tras un año de seguimiento, el análisis bruto no mostró diferencias en los reingresos (74,7 vs. 72,3%; p=0,292) ni en mortalidad (63,9 vs. 61,1%; p=0,239) entre ambos grupos. Tras controlar las variables de confusión, los pacientes en residencias presentaron una mayor mortalidad por todas las causas a un año (hazard ratio 1,153; IC 95%: 1,011-1,317; p=0,034) así como peor supervivencia en el análisis de Kaplan-Meier (log-rank 7,12; p=0,008). Conclusiones: Los pacientes con IC en residencias de ancianos mostraron una mayor mortalidad a un año, que podría deberse a un peor estado funcional, a mayor deterioro cognitivo y a más comorbilidad.(AU)

RESUMO

OBJECTIVE: Two profiles of patients with heart failure with preserved ejection fraction (HFpEF) and type 2 diabetes mellitus (T2DM) can be discerned: those with ischemic and those with diabetic cardiomyopathy (DMC). We aim to analyze clinical differences and prognosis between patients of these two profiles. MATERIAL AND METHODS: This cohort study analyzes data from the Spanish Heart Failure Registry, a multicenter, prospective registry that enrolled patients admitted for decompensated heart failure and followed them for one year. Three groups were created according to the presence of T2DM and heart disease depending on the etiology (ischemic when coronary artery disease was present, or DMC when no coronary, valvular, or congenital heart disease; no hypertension; nor infiltrative cardiovascular disease observed on an endomyocardial biopsy). The groups and outcomes were compared. RESULTS: A total of 466 patients were analyzed. Group 1 (n = 210) included patients with ischemic etiology and T2DM. Group 2 (n = 112) included patients with DMC etiology and T2DM. Group 3 (n = 144), a control group, included patients with ischemic etiology and without T2DM. Group 1 had more hypertension and dyslipidemia; group 2 had more atrial fibrillation (AF) and higher body mass index; group 3 had more chronic kidney disease and were older. In the regression analysis, group 3 had a better prognosis than group 1 (reference group) for cardiovascular mortality and HF readmissions (HR 0.44;95%CI 0.2-1; p = .049). CONCLUSIONS: Patients with T2DM and HFpEF, who had the poorest prognosis, were of two different profiles: either ischemic or DMC etiology. The first had a higher burden of cardiovascular disease and inflammation whereas the second had a higher prevalence of obesity and AF. The first had a slightly poorer prognosis than the second, though this finding was not significant.

RESUMO

BACKGROUND: Individuals suffering from heart failure (HF) and cardiorenal syndrome (CRS) represent a special group of patients considering their age, multiple health issues, and treatment challenges. These factors make them more susceptible to frequent hospital stays and a higher mortality rate. UMIPIC is a multidisciplinary care model program for patients with heart failure follow up provided by internists and nurses who are experts in this entity. Our study delved into the effectiveness of this specialized care program (UMIPIC) in mitigating these risks for HF and CRS patients. METHODS: We analyzed the medical records of 3255 patients diagnosed with HF and CRS types 2 and 4, sourced from the RICA registry. These patients were divided into two distinct groups: those enrolled in the UMIPIC program (1205 patients) and those under standard care (2050 patients). Using propensity score matching, we ensured that both groups were comparable. The study focused on tracking hospital admissions and mortality rates for one year after an HF-related hospital stay. RESULTS: Patients in the UMIPIC group experienced fewer hospital readmissions due to HF compared to their counterparts (20% vs. 32%; Hazard Ratio [HR] = 0.48; 95% Confidence Interval [95% CI]: 0.40-0.57; p < 0.001). They also showed a lower mortality rate (24% vs. 36%; HR = 0.64; 95% CI: 0.54-0.75; p < 0.001). Furthermore, the UMIPIC group had fewer total hospital admissions (36% vs. 47%; HR = 0.58; 95% CI: 0.51-0.66; p < 0.001). CONCLUSIONS: The UMIPIC program, centered on holistic and ongoing care, effectively reduces both hospital admissions and mortality rates for HF and CRS patients after a one-year follow-up period.

RESUMO

Aims: To determine the projected benefits of dapagliflozin after an acute heart failure (HF) event in Spain. Methods: A multicenter and prospective study that included subjects aged 50 years or older consecutively admitted with HF to internal medicine departments in Spain. The projected clinical benefits of dapagliflozin were calculated via pooled analysis of the DAPA-HF and DELIVER trials. Results: A total of 5644 subjects were analyzed, of whom 79.2% were eligible for dapagliflozin, according to criteria of the DAPA-HF and DELIVER trials. Full implementation of dapagliflozin would imply a 1-year absolute risk reduction of 2.3% for death (number needed to treat = 43) and 5.7% (number needed to treat = 17) for HF rehospitalization. Conclusion: Treatment with dapagliflozin could significantly reduce HF burden in clinical practice.


Heart failure is a severe condition that is associated with a high risk of complications. This means that it is important to start using new therapies that have demonstrated a clinical benefit. Clinical trials have shown that dapagliflozin reduces the risk of developing these complications in patients with heart failure. However, it is important to find out whether the results of clinical trials are also seen in real-life populations. We estimated the potential benefits of dapagliflozin in people admitted to hospital more than once with heart failure. The study took place in Spain. Our data suggest that treatment with dapagliflozin could reduce the complications associated with heart failure in real-life patients.

RESUMO

Aims: To address the projected clinical benefits of dapagliflozin among patients with heart failure (HF) with mildly reduced ejection fraction (HFmrEF) and preserved ejection fraction (HFpEF). Methods: A multicenter, prospective, cohort study of patients ≥50 years admitted with HF to Spanish internal medicine departments. The projected clinical benefits of dapagliflozin were calculated from the DELIVER trial. Results: A total of 4049 patients were included; 3271 (80.8%) were eligible for dapagliflozin treatment, according to DELIVER criteria. Within 1 year after discharge, 22.2% were rehospitalized for HF and 21.6% died. Implementation of dapagliflozin would translate into an absolute risk reduction of 1.3% for mortality and 5.1% for HF readmission. Conclusion: HF patients with preserved or mildly reduced ejection fraction have a high risk of events. The use of dapagliflozin could substantially reduce the HF burden.


Heart failure (HF) with preserved ejection fraction is frequent in clinical practice, particularly in the elderly. In HF with preserved ejection fraction, the heart still pumps a similar proportion of blood, but the heart muscle has become thicker. This means there is less space inside the heart to fill with blood, so too little is pumped out each time. Until very recently, no drugs had been shown to provide significant benefits on the outcome of the condition or the chance of recovery for these patients. Fortunately, recent clinical trials have demonstrated that treatment with drugs called SGLT2 inhibitors (e.g., dapagliflozin) could reduce the chance of being admitted to hospital or dying from HF. We investigated the benefits for patients who took dapagliflozin after being admitted to hospital and had HF with mildly reduced or preserved ejection fraction. We saw substantial benefits in this population.

RESUMO

Aim: To estimate the projected effectiveness of dapagliflozin in subjects with heart failure (HF) with reduced ejection fraction in clinical practice in Spain. Materials & methods: This multicenter cohort study included subjects aged 50 years or older consecutively hospitalized for HF in internal medicine departments in Spain. The projected clinical benefits of dapagliflozin were estimated based on results from the DAPA-HF trial. Results: A total of 1595 patients were enrolled, of whom 1199 (75.2%) were eligible for dapagliflozin. Within 1 year after discharge, 21.6% of patients eligible for dapagliflozin were rehospitalized for HF and 20.5% died. Full implementation of dapagliflozin led to an absolute risk reduction of 3.5% for mortality (number needed to treat = 28) and 6.5% (number needed to treat = 15) for HF readmission. Conclusion: Treatment with dapagliflozin in clinical practice may markedly reduce mortality and readmissions for HF.


Heart failure with reduced ejection fraction is a severe disease with a high risk of hospitalization and mortality. With this condition, the heart muscle cannot pump properly. This means that not enough blood is pumped from the heart, reducing the amount of oxygen to the body. Fortunately, there are treatments that reduce this risk, in patients with heart failure. SGLT2 inhibitors, including dapagliflozin, are among the first therapies given to patients with heart failure. In this study, we investigated the potential benefits of adding dapagliflozin to the treatment of patients admitted to the hospital in Spain for heart failure with reduced ejection fraction. Our data showed that dapagliflozin was able to reduce the risk of further events (e.g., heart attack) in these patients.

RESUMO

Atrial fibrillation (AF) is the most common arrhythmia in adults and diabetes mellitus (DM) is a major risk factor for cardiovascular diseases. However, the relationship between both pathologies has not been fully documented and new evidence supports the existence of direct and independent links. In the myocardium, a combination of structural, electrical, and autonomic remodeling may lead to AF. Importantly, patients with AF and DM showed more dramatic alterations than those with AF or DM alone, particularly in mitochondrial respiration and atrial remodeling, which alters conductivity, thrombogenesis, and contractile function. In AF and DM, elevations of cytosolic Ca2⁺ and accumulation of extra cellular matrix (ECM) proteins at the interstitium can promote delayed afterdepolarizations. The DM-associated low-grade inflammation and deposition/infiltration of epicardial adipose tissue (EAT) enforce abnormalities in Ca2+ handling and in excitation-contraction coupling, leading to atrial myopathy. This atrial enlargement and the reduction in passive emptying volume and fraction can be key for AF maintenance and re-entry. Moreover, the stored EAT can prolong action of potential durations and progression from paroxysmal to persistent AF. In this way, DM may increase the risk of thrombogenesis as a consequence of increased glycation and oxidation of fibrinogen and plasminogen, impairing plasmin conversion and resistance to fibrinolysis. Additionally, the DM-associated autonomic remodeling may also initiate AF and its re-entry. Finally, further evidence of DM influence on AF development and maintenance are based on the anti-arrhythmogenic effects of certain anti-diabetic drugs like SGLT2 inhibitors. Therefore, AF and DM may share molecular alterations related to Ca2+ mobility, mitochondrial function and ECM composition that induce atrial remodeling and defects in autonomic stimulation and conductivity. Likely, some specific therapies could work against the associated cardiac damage to AF and/or DM.

RESUMO

Background: Patients with heart failure encompass a heterogeneous group, but they are mostly elderly patients with a large burden of comorbid conditions. Objective: The aim of this study was to compare the clinical characteristics and the prognostic impact on hospital admissions and mortality in a population of patients with HF with different types of caregivers (family members, professionals, and the patient himself). Methods: We conducted an observational study from a prospective registry. Patients from the National Registry of Heart Failure (RICA), which belongs to the Working Group on Heart Failure and Atrial Fibrillation of the Spanish Society of Internal Medicine (SEMI), were included. Patients with heart failure were classified, according to the type of main caregiver, into four groups: the patient himself/herself, a partner, children, or a professional caregiver. A bivariable analysis was performed between the clinical, analytical, therapeutic, and prognostic characteristics of the different groups. The endpoints of the study were all-cause mortality at 1 year; mortality at 120 days; and the readmission rate for HF at 30 days, 120 days, and 1 year of follow-up. In all cases, the level of statistical significance was set at p < 0.05. Results: A total of 2147 patients were enrolled in this study; women represented 52.4%, and the mean age was 81 years. The partner was the caregiver for 703 patients, children were caregivers for 1097 patients, 199 patients had a professional caregiver, and only 148 patients were their own caregivers. Women were more frequently cared for by their children (65.8%) or a professional caregiver (61.8%); men were more frequently cared for by their spouses (68.7%) and more frequently served as their own caregivers (59.5%) (p < 0.001). No statistically significant differences were observed in relation to readmissions or mortality at one year of follow-up between the different groups. A lower probability of readmission and death was observed for patients who received care from a partner or children/relative, with log-rank scores of 11.2 with p= 0.010 and 10.8 with p = 0.013. Conclusions: Our study showed that the presence of a family caregiver for elderly patients with heart failure was associated with a lower readmission rate and a lower mortality rate at 120 days of follow-up. Our study also demonstrated that elderly patients with good cognitive and functional status can be their own caregivers, as they obtained good health outcomes in terms of readmission and mortality. More prospective studies and clinical trials are needed to evaluate the impact of different types of caregivers on the outcomes of patients with heart failure.

RESUMO

Background: Heart failure (HF) is a syndrome with high prevalence, mainly affecting elderly patients, where the presence of associated comorbidities is of great importance. Methods: An observational study from a prospective registry was conducted. Patients identified from the National Registry of Heart Failure (RICA), which belongs to the Working Group on Heart Failure and Atrial Fibrillation of the Spanish Society of Internal Medicine (SEMI), were included. The latter is a prospective, multicenter registry that has been active since 2008. It includes individual consecutive patients over 50 years of age with a diagnosis of HF at hospital discharge (acute decompensated or new-onset HF). Results: In total, 5424 patients were identified from the registry. Forty-seven percent were men and mean left ventricular ejection fraction (LVEF) was 51.4%; 1132 had a score of 0 to 2 according to the PROFUND index, 3087 had a score of 3 to 6, and 952 patients had a score of 7 to 10 points. In the sample, 252 patients had a score above 11 points. At the end of the year of follow-up, 61% of the patients died. This mortality increased proportionally as the PROFUND index increased, specifically 75% for patients with PROFUND greater than 11. The Kaplan-Meier survival curve shows that survival at one year progressively decreases as the PROFUND index value increases. Thus, subjects with scores greater than seven (intermediate-high and high-risk) presented the worst survival with a log rank of 0.96 and a p < 0.05. In the regression analysis, we found a higher risk of death from any cause at one year in the group with the highest risk according to the PROFUND index (score greater than 11 points (HR 1.838 (1.410−2.396)). Conclusions: The PROFUND index is a good index for predicting mortality in patients admitted for acute HF, especially in those subjects at intermediate to high risk with scores above seven. Future studies should seek to determine whether the PROFUND index score is simply a prognostic marker or whether it can also be used to make therapeutic decisions for those subjects with very high short-term mortality.

RESUMO

Objetivo:Evaluar si un valor óptimo de hemoglobina sostenido en los 3 meses posteriores al ingreso por descompensación de insuficiencia cardíaca (IC) reduce la morbimortalidad durante los 12 meses posteriores a un ingreso por IC aguda.Pacientes y método:Estudio retrospectivo de los 1408 pacientes mayores de 65 años incluidos en el registro RICA divididos en 3 grupos: sin anemia (grupo A), anemia recuperada (grupo B) y anemia persistente (grupo C), según los niveles de hemoglobina en el ingreso y a los 3 meses tras el alta. Se construyeron curvas de Kaplan-Meier, comparando los grupos mediante la prueba de log-rank y se realizó un modelo de regresión de Cox para analizar la supervivencia.Resultados:Se incluyeron 578 (41,1%), 299 (21,2%) y 531 (37,7%) en los grupos A, B y C, respectivamente. Registramos un total de 768 muertes y reingresos. Hubo 23 (4%), 12 (4%) y 49 (9,2%) (p=0,001) individuos que fallecieron debido a la IC, y 154 (27%), 73 (24%) y 193 (36%) (p<0,001) reingresaron por esta patología, respectivamente. Los pacientes con anemia persistente tuvieron un riesgo superior de fallecimiento (RR: 1,29; IC95% de 1,04-1,61; p=0,024) o reingreso (1,92; IC95% de 1,16-3,19; p=0,012) por IC.Conclusiones:La anemia persistente en los meses posteriores a un ingreso por IC aumenta la morbimortalidad en el año posterior.

PATIENTS AND METHOD: Retrospective study of the 1408 patients older than 65 years included in the RICA registry divided into 3 groups: no anaemia (group A), recovered anaemia (group B), and persistent anaemia (group C), according to haemoglobin levels on admission, and 3 months after discharge. Kaplan-Meier curves were constructed, comparing the groups using the log-rank test and a Cox regression model was performed to analyse survival. RESULTS: 578 (41.1%), 299 (21.2%) and 531 (37.7%) were included in groups A, B and C, respectively. We recorded a total of 768 deaths and readmissions. There were 23 (4%), 12 (4%) and 49 (9.2%), (p=.001) individuals who died due to HF and 154 (27%), 73 (24%) and 193 (36%) (P<.001) admissions for this pathology, respectively. Patients with persistent anaemia had a higher risk of death (RR 1.29, 95% CI 1.04-1.61, P=.024) or readmission (1.92, 95% CI 1.16-3, 19; P=.012) due to HF. CONCLUSIONS: Persistent anaemia in the months after admission for HF increases morbidity and mortality in the subsequent year.

RESUMO

AIM: To evaluate precipitating factors (PF) of exacerbation in heart failure (HF) and their relationship with age, preserved vs. reduced left ventricular ejection fraction (LVEF) and short-term prognosis. METHODS: We included and followed 2962 patients admitted with acute HF to Internal Medicine Units. Several PF were identified. Differences in PF according to preserved vs. reduced LVEF and age (patients≥80years vs. younger) were analyzed. Primary endpoints were readmission due to worsening HF and all-cause mortality at 3months follow-up. Multivariable Cox models were conducted to identify the independent predictors of 3-months mortality and readmission. RESULTS: More than half of the patients were 80years and over, 47% were women and 61% had preserved LVEF. Atrial fibrillation (AF) and myocardial ischemia were the more common cause of decompensation among octogenarians. It was more frequent to find myocardial ischemia or non-adherence to treatment as precipitants in patients with systolic dysfunction. However, respiratory infections, AF and poor control of blood pressure were more usual in patients with preserved LVEF compared to those with LVEF <50%. Patients admitted for HF precipitated by myocardial ischemia had a higher risk of readmission at 3months (HR 1.49; CI 95%: 1.12-1.99, p=0.006) and the longest hospital stay (12days). PF showed no predictive value for mortality. CONCLUSION: Myocardial ischemia as a PF was an independent marker for HF readmissions at 3-months follow-up. Precipitants are different depending on the age and LVEF of patients. Their identification could improve risk stratification and prevention strategies.

RESUMO

History A 61-year-old man with no relevant medical history was admitted to the emergency department with symptoms of congestive heart failure and a 1-week history of chest pain, progressive dyspnea, abdominal swelling, bipedal edema, and anorexia. Laboratory test results, including complete blood count and electrolyte, creatinine, creatine phosphokinase, and troponin T levels were normal. Electrocardiographic findings were unremarkable. Initial chest radiography showed an enlarged heart with bilateral pleural effusion. Transthoracic echocardiography revealed an irregular right atrial mass and moderate to severe pericardial effusion. The patient subsequently underwent computed tomography (CT) of the chest, abdomen, and pelvis followed by cardiac magnetic resonance (MR) imaging for further evaluation of the atrial mass. Because of the suspected diagnosis, conventional radiography of the skeleton was performed.

RESUMO

Heart failure is a complex syndrome that affects almost all organs and systems of the body. Signs and symptoms of organ dysfunction, in particular kidney dysfunction, may be accentuated or become evident for the first time during acute decompensation of heart failure. Cardiorenal syndrome has been defined as the simultaneous dysfunction of both the heart and the kidney, regardless of which of the two organs may have suffered the initial damage and regardless also of their previous functional status. Research into the mechanisms regulating the complex relationship between the two organs is prompting the search for new biomarkers to help physicians detect renal damage in subclinical stages. Hence, a preventive approach to renal dysfunction may be adopted in the clinical setting in the near future. This article provides a general overview of cardiorenal syndrome and an update of the physiopathological mechanisms involved. Special emphasis is placed on the role of visceral congestion as an emergent mechanism in this syndrome.

RESUMO

La insuficiencia cardíaca es un síndrome complejo que afecta prácticamente la totalidad de órganos y sistemas de la economía. En los frecuentes episodios de agudización o descompensación, la afectación orgánica se acentúa o incluso se hace patente por vez primera. De entre los órganos más íntimamente relacionados con las descompensaciones, es el riñón el que juega un papel más protagonista. La coexistencia en la afectación de ambos órganos, sea cual sea el inicialmente involucrado y sea cual sea el estadio evolutivo de su disfunción, es lo que en los últimos años se ha denominado como síndrome cardiorrenal. La investigación sobre los mecanismos que regulan la compleja relación entre ambos órganos está propiciando una intensa búsqueda de nuevos biomarcadores que permitan detectar el daño renal en estadios subclínicos. Algo que permitirá, en un futuro inmediato, actuar protegiendo los riñones mucho antes de la pérdida de su función. En la presente revisión se ofrece una visión general de dicho síndrome y se repasan los mecanismos fisiopatológicos involucrados, con especial énfasis en el papel de la congestión visceral como uno de los mecanismos emergentes en el síndrome cardiorrenal (AU)

RESUMO

Fundamento y objetivo: El déficit de vitamina D y la hormona paratiroidea (PTH) están asociados a un incremento del riesgo cardiovascular y de rigidez arterial. El objetivo de nuestro estudio es comparar el riesgo cardiovascular en sujetos con insuficiencia de vitamina D, según su concentración de PTH, así como evaluar la respuesta tras la administración de vitamina D. Pacientes y método: Estudio prospectivo de pacientes con concentración de 25(OH)-vitamina D menor de 30 nmol/l. Se evaluaron parámetros de riesgo vascular como presión arterial, rigidez arterial, perfil lipídico y metabolismo de la glucosa. Los pacientes recibieron suplementos de vitamina D durante 3 meses, tras lo cual se reevaluaron los parámetros previos. Resultados: Se incluyeron un total de 32 pacientes. Aquellos con PTH mayor de 65 pg/ml tenían mayor edad, peor función renal, mayor presión arterial sistólica, mayor presión de pulso y mayor rigidez arterial. El tratamiento con vitamina D mostró una tendencia no estadísticamente significativa a reducir la presión arterial y la rigidez arterial. Conclusiones: El incremento de PTH en pacientes con insuficiencia de vitamina D implica un peor control de la presión arterial y una mayor rigidez vascular. La reposición con vitamina D muestra una tendencia a reducir estos parámetros (AU)

RESUMO

BACKGROUND AND OBJECTIVES: Vitamin D deficiency and parathyroid hormone (PTH) are associated with an increased cardiovascular risk and arterial stiffness. The aim of our study is to compare the cardiovascular risk in subjects with low vitamin D, attending to the PTH concentration, as well as evaluating the response after administration of vitamin D. PATIENTS AND METHODS: Prospective study of patients with a concentration of 25(OH)-vitamin D below 30nmol/l. We evaluated vascular risk parameters as blood pressure, arterial stiffness, lipid profile and glucose metabolism. Patients received vitamin D supplements for 3 months, after which the previous parameters were reassessed. RESULTS: A total of 32 patients were included. Those with PTH over 65pg/ml were older, had worse renal function, higher systolic blood pressure, pulse pressure and arterial stiffness. Treatment with vitamin D showed a statistically significant trend to lower blood pressure and pulse wave velocity. CONCLUSIONS: The increase in PTH in patients with low vitamin D involves poor control of blood pressure and increased vascular stiffness. Vitamin D replacement shows a tendency to reduce these parameters.
