RESUMO

Specific foods, nutrients, dietary patterns, and physical activity are associated with lower blood pressure (BP) and heart rate (HR), but little is known about the joint effect of lifestyle factors captured in a multidimensional score. We assessed the association of a validated Mediterranean-lifestyle (MEDLIFE) index with 24-h-ambulatory BP and HR in everyday life among community-living older adults. Data were taken from 2,184 individuals (51% females, mean age: 71.4 years) from the Seniors-ENRICA-2 cohort. The MEDLIFE index consisted of 29 items arranged in three blocks: 1) Food consumption; 2) Dietary habits; and 3) Physical activity, rest, and conviviality. A higher MEDLIFE score (0-29 points) represented a better Mediterranean lifestyle adherence. 24-h-ambulatory BP and HR were obtained with validated oscillometric devices. Analyses were performed with linear regression adjusted for the main confounders. The MEDLIFE-highest quintile (vs Q1) was associated with lower nighttime systolic BP (SBP) (-3.17 mmHg [95% CI: -5.25, -1.08]; p-trend = 0.011), greater nocturnal-SBP fall (1.67% [0.51, 2.83]; p-trend = 0.052), and lower HR (-2.04 bpm [daytime], -2.33 bpm [nighttime], and -1.93 bpm [24-h]; all p-trend < 0.001). Results were similar for each of the three blocks of MEDLIFE and by hypertension status (yes/no). Among older adults, higher adherence to MEDLIFE was associated with lower nighttime SBP, greater nocturnal-SBP fall, and lower HR in their everyday life. These results suggest a synergistic BP-related protection from the components of the Mediterranean lifestyle. Future studies should determine whether these results replicate in older adults from other Mediterranean and non-Mediterranean countries.

RESUMO

Central (aortic) systolic blood pressure (cSBP) is the pressure seen by the heart, the brain, and the kidneys. If properly measured, cSBP is closer associated with hypertension-mediated organ damage and prognosis, as compared with brachial SBP (bSBP). We investigated 24-hour profiles of bSBP and cSBP, measured simultaneously using Mobilograph devices, in 2423 untreated adults (1275 women; age, 18-94 years), free from overt cardiovascular disease, aiming to develop reference values and to analyze daytime-nighttime variability. Central SBP was assessed, using brachial waveforms, calibrated with mean arterial pressure (MAP)/diastolic BP (cSBPMAP/DBPcal), or bSBP/diastolic blood pressure (cSBPSBP/DBPcal), and a validated transfer function, resulting in 144 509 valid brachial and 130 804 valid central measurements. Averaged 24-hour, daytime, and nighttime brachial BP across all individuals was 124/79, 126/81, and 116/72 mm Hg, respectively. Averaged 24-hour, daytime, and nighttime values for cSBPMAP/DBPcal were 128, 128, and 125 mm Hg and 115, 117, and 107 mm Hg for cSBPSBP/DBPcal, respectively. We pragmatically propose as upper normal limit for 24-hour cSBPMAP/DBPcal 135 mm Hg and for 24-hour cSBPSBP/DBPcal 120 mm Hg. bSBP dipping (nighttime-daytime/daytime SBP) was -10.6 % in young participants and decreased with increasing age. Central SBPSBP/DBPcal dipping was less pronounced (-8.7% in young participants). In contrast, cSBPMAP/DBPcal dipping was completely absent in the youngest age group and less pronounced in all other participants. These data may serve for comparison in various diseases and have potential implications for refining hypertension diagnosis and management. The different dipping behavior of bSBP versus cSBP requires further investigation.

RESUMO

Patients with coronary heart disease (CHD) can be particularly susceptible to the adverse effects of excessive blood pressure (BP) lowering by antihypertensive treatment. The identification of hypotension is thus especially important. This study estimated the prevalence of hypotension among CHD-treated hypertensive patients undergoing ambulatory blood pressure monitoring (ABPM) in routine clinical practice. We performed a cross-sectional study with 2892 CHD-treated hypertensive patients from the Spanish ABPM Registry. Based on previous studies, hypotension was defined as systolic/diastolic BP < 120 and/or 70 mmHg according to office measurements, <115 and/or 65 mmHg according to daytime ABPM, <100 and/or 50 mmHg according to nighttime ABPM, and <110 and/or 60 mmHg according to 24 h ABPM. The participants' mean age was 67.1 years (69.8% men). A total of 19.6% of the patients had office hypotension, 26.5% had daytime hypotension, 9.0% had nighttime hypotension, and 16.1% had 24-hr ABPM hypotension. Low diastolic BP values were responsible for most cases of hypotension. Fifty-eight percent of the cases of hypotension detected by daytime ABPM did not correspond to hypotension according to office BP. The variables independently associated with daytime ambulatory systolic/diastolic hypotension and diastolic hypotension (the latter being the most frequent type of ambulatory hypotension) were age, female sex, and the number of antihypertensive medications. In conclusion, in a large ABPM registry, one out of every four CHD-treated hypertensive patients was potentially at risk because of hypotension according to daytime ABPM, and more than half of them were not identified if office BP was relied on alone. We suggest that ABPM should be performed in these patients.

RESUMO

INTRODUCTION: Air in urban areas is usually contaminated with particle matter. High concentrations lead to a rise in the risk of cardiovascular and respiratory diseases. Some studies have reported that ultrafine particles (UFP) play a greater role in cardiovascular diseases than other particle matter, particularly regarding hypertensive crises and DBP, although in the latter such effects were described concerning clinical blood pressure (BP). In this study, we evaluate the relationship between 24-h ambulatory BP monitoring (ABPM) and atmospheric UFP concentrations in Barcelona. METHODS: An observational study of individual patients' temporal and geographical characteristics attended in Primary Care Centres and Hypertensive Units during 2009-2014 was performed. RESULTS: The participants were 521 hypertensive patients, mean age 56.8 years (SD 14.5), 52.4% were women. Mean BMI was 28.0 kg/m and the most prominent cardiovascular risk factors were diabetes (N = 66, 12.7%) and smoking (N = 79, 15.2%). We describe UFP effects at short-term and up to 1 week (from lag 0 to 7). For every 10 000 particle/cm UFP increase measured at an urban background site, a corresponding statistically significant increase of 2.7 mmHg [95% confidence interval = (0.5-4.8)] in 24-h DBP with ABPM for the following day was observed (lag 1). CONCLUSION: We have observed that a rise in UFP concentrations during the day prior to ABPM is significantly associated with an increase in 24 h and diurnal DBP. It has been increasingly demonstrated that UFP play a key role in cardiovascular risk factors and, as we have demonstrated, in good BP control.

RESUMO

Nephrotoxicity is an important limitation to the clinical use of many drugs and contrast media. Drug nephrotoxicity occurs in acute, subacute and chronic manifestations ranging from glomerular, tubular, vascular and immunological phenotypes to acute kidney injury. Pre-emptive risk assessment of drug nephrotoxicity poses an urgent need of precision medicine to optimize pharmacological therapies and interventional procedures involving nephrotoxic products in a preventive and personalized manner. Biomarkers of risk have been identified in animal models, and risk scores have been proposed, whose clinical use is abated by their reduced applicability to specific etiological models or clinical circumstances. However, our present data suggest that the urinary level of transferrin may be indicative of risk of renal damage, where risk is induced by subclinical tubular alterations regardless of etiology. In fact, urinary transferrin pre-emptively correlates with the subsequent renal damage in animal models in which risk has been induced by drugs and toxins affecting the renal tubules (i.e. cisplatin, gentamicin and uranyl nitrate); whereas transferrin shows no relation with the risk posed by a drug affecting renal hemodynamics (i.e. cyclosporine A). Our experiments also show that transferrin increases in the urine in the risk state (i.e. prior to the damage) precisely as a consequence of reduced tubular reabsorption. Finally, urinary transferrin pre-emptively identifies subpopulations of oncological and cardiac patients at risk of nephrotoxicity. In perspective, urinary transferrin might be further explored as a wider biomarker of an important mechanism of predisposition to renal damage induced by insults causing subclinical tubular alterations.

RESUMO

OBJECTIVES: Unlike the 2018 European Society of Cardiology/European Society of Hypertension (ESC/ESH) guideline, the 2017 American College of Cardiology/American Heart Association (ACC/AHA) guideline has recommended a shift in hypertension definition from blood pressure (BP) 140/90-130/80 mmHg. Further, they proposed somewhat different indications for antihypertensive medication. No data are available on the comprehensive impact of these guidelines in European countries, where physicians do not always follow guidelines from their own continent. We estimated the prevalence of hypertension, recommendations for antihypertensive medication, and cardiometabolic goals achieved in Spain using the ESC/ESH versus ACC/AHA guidelines. METHODS: We analyzed data from a national survey on 12074 individuals representative of the population aged at least 18 years in Spain. BP was measured with standardized procedures. RESULTS: According to the ESC/ESH and ACC/AHA guidelines, hypertension prevalence was 33.1% (95% confidence interval: 32.2-33.9%) and 46.9% (46.0-47.8%), respectively, and antihypertensive medication was recommended for 33.5% (32.7-34.3%) and 37.2% (36.3-38.1%) of adults, respectively. This represents 5.3 more million hypertensive patients and 1.4 more million candidates for medication (for a 40-million-adults' country) using the ACC/AHA versus the ESC/ESH guideline. Participants who were hypertensive under the ACC/AHA but not the ESC/ESH guideline achieved less frequently some cardiometabolic goals (e.g. nonsmoking, reduced salt consumption, LDL cholesterol if hypercholesterolemic, lifestyle medical advice, and treatment with renin-angiotensin-system blockers where indicated) than those who were hypertensive under the ESC/ESH guideline. CONCLUSION: The implementation of the ACC/AHA versus the ESC/ESH guideline would result in a substantial increase in the prevalence of hypertension and the number of adults who should receive medication. There is room for improvement in lifestyles and cardioprotective treatment in individuals with BP of 130-9/80-9 mmHg whether they are called hypertensive (ACC/AHA) or not (ESC/ESH). We suggest that clinical-practice guidelines should consider the public health and costs implications, and not only the evidence on effectiveness and cost-effectiveness, of their recommendations.

RESUMO

United States and European guidelines have recommended new treatment goals for office blood pressure (BP). We examined 9784 hypertensives of the Spanish Ambulatory BP Monitoring (ABPM) registry with office BP treated to the prior goal (<140/90 mm Hg); and evaluated the frequency and all-cause mortality of 4 BP strata depending on whether or not they attained more conservative or new office BP goal (130-139/80-89 and <130/80 mm Hg, respectively) and whether or not BP was controlled according to ABPM criteria in the European and US guidelines (24-hour ambulatory BP <130/80 and <125/75 mm Hg, respectively). Whether achieving or not the new office BP goal, the total-mortality risk during a 5-year follow-up was only significantly higher than the reference (normal office BP and ABPM) when 24-hour ambulatory BP was above goal (hazard ratio from multivariable Cox models was in the range of 2.4-2.9; P<0.001). The frequency of patients achieving the new office BP goal was 34.4%, and the frequencies of those not achieving the ABPM goal were 31.6% and 53.7% using the 130/80 or the 125/75 ABPM goal, respectively. Mean office systolic BP was 129 mm Hg for patients not achieving the ABPM goal. In hypertensive patients controlled under prior office BP goal, the frequency of those achieving new office BP goal <130/80 was high, suggesting this goal can be attained. In addition, patients had a higher mortality risk only when ABPM was above goal despite having mean office systolic BP under control, a condition that was also common.

RESUMO

INTRODUCCIÓN: La enfermedad renal crónica (ERC) constituye un problema de salud pública a nivel mundial. Los objetivos de este estudio fueron estimar la prevalencia de ERC en España y evaluar el impacto de la acumulación de factores de riesgo cardiovascular (FRCV) en la prevalencia. MATERIAL Y MÉTODOS: Análisis del Estudio de Nutrición y Riesgo Cardiovascular en España (ENRICA), estudio epidemiológico de ámbito nacional, de base poblacional, con una muestra de 11.505 sujetos representativos de la población adulta española. La información se recogió mediante cuestionarios estandarizados, exploración física y colección de muestras de sangre y orina que se analizaron en un laboratorio centralizado. La ERC se definió según las guías KDIGO en curso. Se analizó la relación de la ERC con 10 FRCV (edad, hipertensión arterial, obesidad, obesidad abdominal, tabaquismo, colesterol LDL elevado, colesterol HDL disminuido, hipertrigliceridemia, diabetes y sedentarismo. RESULTADOS: La prevalencia de ERC fue del 15,1% (IC 95%: 14,3-16,0). La ERC fue más frecuente en varones (23,1% vs. 7,3% en mujeres), según aumentaba la edad (4,8% en sujetos de 18-44 años, 17,4% en sujetos de 45-64 años, y 37,3% en sujetos ≥ 65 años), y en sujetos con enfermedad cardiovascular (39,8% vs. 14,6% en sujetos sin enfermedad cardiovascular); todas las comparaciones con p < 0,001. La ERC afectó al 4,5% de los sujetos con 0-1FRCV, con un aumento progresivo desde el 10,4 al 52,3% en sujetos con 2 a 8-10FRCV (p de tendencia < 0,001). CONCLUSIONES: La ERC afecta a uno de cada 7 adultos en España, una prevalencia más elevada que la estimada en estudios previos en nuestro país y similar a la observada en Estados Unidos. La ERC afecta particularmente a los varones, a sujetos de edad avanzada o con enfermedad cardiovascular. La prevalencia de ERC aumenta de forma marcada con la acumulación de FRCV, lo que sugiere que la ERC en la población podría considerarse como un trastorno cardiovascular


BACKGROUND: Chronic kidney disease (CKD) is a public health problem worldwide. We aimed to estimate the CKD prevalence in Spain and to examine the impact of the accumulation of cardiovascular risk factors (CVRF). MATERIAL AND METHODS: We performed a nationwide, population-based survey evaluating 11,505 individuals representative of the Spanish adult population. Information was collected through standardised questionnaires, physical examination, and analysis of blood and urine samples in a central laboratory. CKD was graded according to current KDIGO definitions. The relationship between CKD and 10CVRF was assessed (age, hypertension, general obesity, abdominal obesity, smoking, high LDL-cholesterol, low HDL-cholesterol, hypertriglyceridaemia, diabetes and sedentary lifestyle). RESULTS: Prevalence of CKD was 15.1% (95%CI: 14.3-16.0%). CKD was more common in men (23.1% vs 7.3% in women), increased with age (4.8% in 18-44 age group, 17.4% in 45-64 age group, and 37.3% in ≥ 65), and was more common in those with than those without cardiovascular disease (39.8% vs 14.6%); all P <.001. CKD affected 4.5% of subjects with 0-1CVRF, and then progressively increased from 10.4% to 52.3% in subjects with 2 to 8-10CVRF (P trend <.001). CONCLUSIONS: CKD affects one in seven adults in Spain. The prevalence is higher than previously reported and similar to that in the United States. CKD was particularly prevalent in men, older people and people with cardiovascular disease. Prevalence of CKD increased considerably with the accumulation of CVRF, suggesting that CKD could be considered as a cardiovascular condition

RESUMO

BACKGROUND: Evidence for the influence of ambulatory blood pressure on prognosis derives mainly from population-based studies and a few relatively small clinical investigations. This study examined the associations of blood pressure measured in the clinic (clinic blood pressure) and 24-hour ambulatory blood pressure with all-cause and cardiovascular mortality in a large cohort of patients in primary care. METHODS: We analyzed data from a registry-based, multicenter, national cohort that included 63,910 adults recruited from 2004 through 2014 in Spain. Clinic and 24-hour ambulatory blood-pressure data were examined in the following categories: sustained hypertension (elevated clinic and elevated 24-hour ambulatory blood pressure), "white-coat" hypertension (elevated clinic and normal 24-hour ambulatory blood pressure), masked hypertension (normal clinic and elevated 24-hour ambulatory blood pressure), and normotension (normal clinic and normal 24-hour ambulatory blood pressure). Analyses were conducted with Cox regression models, adjusted for clinic and 24-hour ambulatory blood pressures and for confounders. RESULTS: During a median follow-up of 4.7 years, 3808 patients died from any cause, and 1295 of these patients died from cardiovascular causes. In a model that included both 24-hour and clinic measurements, 24-hour systolic pressure was more strongly associated with all-cause mortality (hazard ratio, 1.58 per 1-SD increase in pressure; 95% confidence interval [CI], 1.56 to 1.60, after adjustment for clinic blood pressure) than the clinic systolic pressure (hazard ratio, 1.02; 95% CI, 1.00 to 1.04, after adjustment for 24-hour blood pressure). Corresponding hazard ratios per 1-SD increase in pressure were 1.55 (95% CI, 1.53 to 1.57, after adjustment for clinic and daytime blood pressures) for nighttime ambulatory systolic pressure and 1.54 (95% CI, 1.52 to 1.56, after adjustment for clinic and nighttime blood pressures) for daytime ambulatory systolic pressure. These relationships were consistent across subgroups of age, sex, and status with respect to obesity, diabetes, cardiovascular disease, and antihypertensive treatment. Masked hypertension was more strongly associated with all-cause mortality (hazard ratio, 2.83; 95% CI, 2.12 to 3.79) than sustained hypertension (hazard ratio, 1.80; 95% CI, 1.41 to 2.31) or white-coat hypertension (hazard ratio, 1.79; 95% CI, 1.38 to 2.32). Results for cardiovascular mortality were similar to those for all-cause mortality. CONCLUSIONS: Ambulatory blood-pressure measurements were a stronger predictor of all-cause and cardiovascular mortality than clinic blood-pressure measurements. White-coat hypertension was not benign, and masked hypertension was associated with a greater risk of death than sustained hypertension. (Funded by the Spanish Society of Hypertension and others.).

RESUMO

BACKGROUND AND AIM: Treatment-resistant hypertension (TRH) is associated with particular clinical features, nonadherence, and suboptimal treatment. We assessed possible associations of antihypertensive drug classes, specific agents inside each class, and types of combinations, with the presence of non-TRH vs. TRH, and with controlled vs. uncontrolled TRH. METHODS: Comparisons were done in 14 264 patients treated with three drugs (non-TRH: 2988; TRH: 11 276) and in 6974 treated with at least four drugs (controlled TRH: 1383; uncontrolled TRH: 5591). Associations were adjusted for age, sex, and previous cardiovascular event. RESULTS: In both groups of patients treated with three or with at least four drugs, aldosterone antagonists among drug classes [adjusted odds ratio (OR): 1.82 and 1.41, respectively], and ramipril (OR: 1.28 and 1.30), olmesartan (OR: 1.31 and 1.37), and amlodipine (OR: 1.11 and 1.41) inside each class were significantly associated with blood pressure control (non-TRH or controlled TRH). In patients treated with three drugs, non-TRH was also associated with the use of chlorthalidone (OR: 1.50) and bisoprolol (OR: 1.19), whereas in patients treated with at least four drugs, controlled TRH was significantly associated with the triple combination of a renin-angiotensin system blocker, a calcium channel blocker, and a diuretic (OR: 1.17). CONCLUSION: The use of aldosterone antagonists is associated with blood pressure control in patients treated with three or more drugs. Similar results are observed with specific agents inside each class, being ramipril, olmesartan, chlorthalidone, amlodipine, and bisoprolol those exhibiting significant results. An increased use of these drugs might probably reduce the burden of TRH.

RESUMO

OBJECTIVE: Increased BP-variability predicts cardiovascular morbidity and mortality in hypertensives. This study aimed to examine short-term BP-variability according to renal function stage. METHODS: We included 16 546 patients [10 270 (62.1%) without/6276 (38.9%) with CKD Stage 1-5] from the Spanish Ambulatory-Blood-Pressure Monitoring (ABPM) Registry. Stages of CKD were defined according to K/DIGO criteria, based on estimated glomerular filtration rate calculated with the CKD-EPI equation and albumin-to-creatine ratio. BP-variability was assessed with standard deviation (SD), weighted SD (wSD), coefficient of variation (CV), and average real variability (ARV). RESULTS: Compared with those without CKD, a lower proportion of CKD patients were dippers (51.9 versus 39.6%; P < 0.001). Across CKD stages, a progressive decrease in dipper (from 39.1 to 20.4%; P < 0.001) and increase in riser proportion (from 12.3 to 36.7%; P < 0.001) were noted. Patients with CKD had significantly higher SBP SD, wSD, CV and ARV and lower DBP SD compared with those without CKD (P < 0.001). Within CKD Stages, an increasing trend from Stage 1 towards Stage 5 was observed for SBP SD (from 13.8 ±â€Š3.7 to 15.6 ±â€Š5.4 mmHg), wSD (from 12.0 ±â€Š3.2 to 13.9 ±â€Š5.1 mmHg), CV (from 10.4 ±â€Š2.7 to 11.5 ±â€Š4.1%), ARV (from 9.9 ±â€Š2.3 to 11.4 ±â€Š3.2 mmHg); P < 0.001 for all comparisons. DBP SD (P < 0.001), wSD and ARV (P = 0.002) were slightly decreasing, whereas DBP CV increased from Stage 1 to Stage 4 (P < 0.001). In multivariate analysis, male gender, older age, abdominal obesity, diabetes, number of antihypertensive medications, and clinic SBP were independent factors for higher SBP 24-h ARV in CKD. CONCLUSION: An increase in short-term SBP-variability was present with advancing CKD stages in a large cohort. This increased SBP-variability may be involved in the sharp elevation of cardiovascular risk with worsening renal function.

RESUMO

BACKGROUND AND AIM: The prevalence and associated risks of white-coat hypertension (WCH) are still a matter of debate. We aimed to assess differences in prevalence and associated conditions of WCH defined on the basis of the normality of all daytime, night-time, and 24-h blood pressure (BP), only daytime, or only 24-h BP. METHODS: We selected 115 708 patients (45 020 untreated and 70 688 treated) from the Spanish Ambulatory BP Monitoring Registry. WCH was estimated in patients with elevated office BP (≥140 and/or 90 mmHg) by using normal daytime (<135/85) BP, normal 24-h BP (<130/80), or normal daytime, night-time (<120/70) and 24-h BP. Demographic and clinical data (associated risk factors and organ damage) were compared among groups. RESULTS: Prevalence of WCH was 41.3, 35.2, and 26.1% in untreated, and 45.8, 38.9, and 27.2% in treated patients with elevated office BP, by using the criteria of daytime, 24-h, or all ambulatory periods. Compared with the normotensive group, WCH defined by normal daytime, night-time, and 24-h BP did not significantly differ in terms of other cardiovascular risk factors or organ damage. In contrast, patients from other groups (either only normal daytime BP or 24-h BP) had significantly more prevalence of diabetes, dyslipidaemia, microalbuminuria, left ventricular hypertrophy, reduced renal function, and previous history of cardiovascular disease. CONCLUSION: Prevalence of WCH is dependent on definition criteria. Only diagnostic criteria which considers the normality of all ambulatory periods identifies patients with cardiovascular risk similar to normotensive patients. These results support using such criteria for a more accurate definition of WCH.

RESUMO

BACKGROUND AND OBJECTIVE: Elderly patients can be particularly susceptible to the adverse effects of excessive blood pressure (BP) lowering by antihypertensive treatment. The identification of hypotension is thus especially important. Ambulatory BP monitoring (ABPM) is a more accurate technique than office for classifying BP status. This study examined the prevalence of hypotension and associated demographic and clinical factors among very old treated hypertensive patients undergoing ABPM. DESIGN, SETTING, AND PARTICIPANTS: Cross-sectional study in which 5066 patients aged 80 years and older with treated hypertension drawn from the Spanish ABPM Registry were included. MEASUREMENTS: Office BP and 24-hour ambulatory BP were determined using validated devices under standardized conditions. Based on previous studies, hypotension was defined as systolic/diastolic BP <110 and/or 70 mmHg with office measurement, <105 and/or 65 mmHg with daytime ABPM, <90 and/or 50 mmHg with nighttime ABPM, and <100 and/or 60 mmHg with 24-hour ABPM. RESULTS: Participants' mean age was 83.2 ± 3.1 years (64.4% women). Overall, 22.8% of patients had office hypotension, 33.7% daytime hypotension, 9.2% nighttime hypotension, and 20.5% 24-hour ABPM hypotension. Low diastolic BP values were responsible for 90% of cases of hypotension. In addition, 59.1% of the cases of hypotension detected by daytime ABPM did not correspond to hypotension according to office BP. The variables independently associated with office and ABPM hypotension were diabetes, coronary heart disease, and a higher number of antihypertensive medications. CONCLUSIONS: One in 3 very elderly treated hypertensive patients attended in usual clinical practice were potentially at risk of having hypotension according to daytime ABPM. More than half of them had masked hypotension; that is, they were not identified if relying on office BP alone. Thus, ABPM could be especially helpful for identifying ambulatory hypotension and avoiding overtreatment, in particular, in patients with diabetes, heart disease, or on antihypertensive polytherapy.

RESUMO

Hyperprolactinemia is an underappreciated/unknown adverse effects of antipsychotics. The consequences of hyperprolactinemia compromise therapeutic adherence and can be serious. We present the consensus recommendations made by a group of experts regarding the management of antipsychotic-induced hyperprolactinemia. The current consensus was developed in 3 phases: 1, review of the scientific literature; 2, subsequent round table discussion to attempt to reach a consensus among the experts; and 3, review by all of the authors of the final conclusions until reaching a complete consensus. We include recommendations on the appropriate time to act after hyperprolactinemia detection and discuss the evidence on available options: decreasing the dose of the antipsychotic drug, switching antipsychotics, adding aripiprazole, adding dopaminergic agonists, and other type of treatment. The consensus also included recommendations for some specific populations such as patients with a first psychotic episode and the pediatric-youth population, bipolar disorder, personality disorders and the elderly population.
