RESUMO

Purpose: High blood pressure (HBP) is the leading cause of mortality and years of disability, and its prevalence is increasing. Therefore, diagnosis and effective treatment of HBP is one of the main goals to prevent and reduce its complications, and pharmacological treatment is the cornerstone of hypertension management.Materials and Methods: The gradual introduction of different drug families has led to the development of new molecules that have improved efficacy and reduced adverse effects. Results: Current drugs include a large number that target key mechanisms of blood pressure regulation as well as those that contribute to hypertension-induced organ damage. Recently, new antihypertensive drugs have been introduced that not only aim to lower blood pressure but also provide additional protection against organ damage and metabolic disorders. Some of them were introduced for specific indications other than hypertension and other are based in a pharmacogenomic approach. Other routes of administration, such subcutaneous injection, are also being explored to improve protection and compliance.Conclusions: The main characteristics of each class of antihypertensive drug are summarised.

RESUMO

Diabetes, especially type 2, is considered a risk situation for atherosclerotic cardiovascular disease (ASCVD). Subjects with diabetes type 2 have a mortality rate due to ASCVD 3 times higher than that found in the general population, attributed to hyperglycemia and the frequent association of other cardiovascular risk factors, such as atherogenic dyslipidemia. Numerous scientific societies have established a risk classification for ASCVD in diabetes based on 3 degrees (moderate, high and very high). The objectives of dyslipidemia control are clearly defined and accepted, and vary depending on the previously established cardiovascular risk. In moderate or intermediate risk, the guidelines propose a less intensive intervention, maintaining LDL-C levels<100mg/dL and NO-HDL-C levels<130mg/dL, and waiting 10 years until reaching the high-risk category to initiate more intensive treatment. However, during the decade of follow-up recommended in the guidelines, cholesterol deposition in the arterial wall increases, facilitating the development of an unstable and inflammatory atheromatous plaque, and the development of ASCVD. Alternatively, diabetes could be considered from the outset to be a high-risk situation and the goal should be LDL-C<70mg/dL. Furthermore, maintaining LDL-C levels<70mg/dL contributes to reducing and stabilizing atheromatous plaque, avoiding or reducing mortality episodes due to ASCVD during those years of diabetes evolution. Should we maintain the proposed objectives in subjects with diabetes and moderate risk for a decade until reaching the high cardiovascular risk phase or, on the contrary, should we adopt a more intensive stance from the beginning seeking to reduce cardiovascular risk in the majority of patients with diabetes? Is it better to wait or prevent with effective therapeutic measures from the first moment?

RESUMO

Heads of government with cerebrovascular arteriosclerosis and other diseases in key historical moments have led to decisions that have marked the destiny of countries not always in a beneficial direction. Severe diseases in political leaders in power have often been hidden from citizens with the collaboration of personal physicians. The confidentiality of the patient-doctor relationship in special political circumstances should be reexamined and subjected to debate. Legal provisions to ensure total transparency of medical information about the health of heads of government should be implemented. Transparency ensures the trust of citizens.

RESUMO

: Chronic kidney disease (CKD) is a public health threat with impact in cardiovascular risk. All forms of cardiovascular disease and mortality are more common in CKD. Treatment of cardiovascular risk factors, hypertension, dyslipidemia and diabetes is essential for cardiovascular and kidney protection. CKD is a marker of high or very high cardiovascular risk and its presence require early treatment and specific goals. Lifestyle is a pivotal factor, stopping smoking, reducing weight in the overweight or obese, starting regular physical exercise and healthy dietary pattern are recommended. Office BP should be lowered towards 130/80 mmHg or even lower if tolerated with sodium restriction and single pill combination, including angiotensin system blocker. Out-of-office BP monitoring, mainly 24-h assessment, is recommended. Diabetes requires treatment from the moment of diagnosis, but prediabetes benefits with lifestyle changes and metformin in patients stage 2 and 3a. iSGLT2 and GLP-1RA are initially recommended in T2D patients with high or very high cardiovascular risk. Concerning dyslipidemia, for patients in stage 4, LDL-C 55 mg/dl or less (1.4 mmol/l) and an LDL-C reduction of 50% or less from baseline is recommended. In stage 3, LDL-C goal is 70 mg/dl or less (1.8 mmol/l) and an LDL-C. reduction of at least 50% from baseline. Statins are the lipid-lowering therapy of choice with or without ezetimibe. Higher doses of statins are required as GFR declines. Available evidence suggests that combined PCSK9 inhibitors with maximally tolerated dose of statins may have an emerging role in treatment of dyslipidemia in CKD patients.

RESUMO

PURPOSE OF REVIEW: Observational studies and meta-analyses of randomized clinical trials data have revealed a 10-12% increased risk of new-onset diabetes (NOD) associated with statin therapy; the risk is increased with intensive treatment regimens and in people with features of the metabolic syndrome or prediabetes. The purpose of this review is to provide an updated summary of what is known about the potential mechanisms for the diabetogenic effect of statins. RECENT FINDINGS: Hydroxyl methyl glutaryl coenzyme A reductase (HMGCoAR) is the target of statin therapy and the activity of this key enzyme in cholesterol synthesis is reduced by statins in a partial and reversible way. Mendelian randomization studies suggest that the effect of statins on glucose homeostasis reflect reduced activity of HMGCoAR. In vitro and in vivo data indicate that statins reduce synthesis of mevalonate pathway products and increase cholesterol loading, leading to impaired ß-cell function and decreased insulin sensitivity and insulin release. While this effect has been thought to be a drug class effect, recent insights suggest that pravastatin and pitavastatin could exhibit neutral effects on glycaemic parameters in patients with and without diabetes mellitus. The mechanisms by which statins might lead to the development of NOD are unclear. The inhibition of HMGCoAR activity by statins appears to be a key mechanism. It is difficult to offer a comprehensive view regarding the diabetogenic effect of statins because our understanding of the most widely recognized potential mechanisms, i.e. underlying statin-induced reduction of insulin sensitivity and/or insulin secretion, is still far from complete. The existence of this dual mechanism is supported by the results of a study in a large group of non-diabetic men, showing that a 46% higher risk of NOD in statin users compared to non-users was accompanied by a significant 12% reduction in insulin secretion and a 24.3% increase in insulin resistance. Although statin therapy is associated with a modest increase in the risk of NOD (about one per thousand patient-years), patients should be reassured that the benefits of statins in preventing cardiovascular disease (CVD) events far outweigh the potential risk from elevation in plasma glucose.

RESUMO

OBJECTIVE: To study the association of genes involved in the mitochondrial respiratory chain (MRC) pathway with body mass index (BMI) and obesity risk. DESIGN: This work studies three cross-sectional populations from Spain, representing three provinces: HORTEGA (Valladolid, Northwest/Centre), SEGOVIA (Segovia, Northwest/centre) and PIZARRA (Malaga,South). SETTING: Forty-eight single nucleotide polymorphisms (SNPs) from MRC genes were selected and genotyped by SNPlex method. Association studies with BMI and obesity risk were performed for each population. These associations were then verified by analysis of the studied population as a whole (3731 samples). PARTICIPANTS: A total of 3731 Caucasian individuals: 1502 samples from HORTEGA, 988 from PIZARRA and 1241 from SEGOVIA. RESULTS: rs4600063 (SDHC), rs11205591 (NDUFS5) and rs10891319 (SDHD) SNPs were associated with BMI and obesity risk (p values for BMI were 0.04, 0.0011 and 0.0004, respectively, and for obesity risk, 0.0072, 0.039 and 0.0038). However, associations between rs4600063 and BMI and between these three SNPs and obesity risk are not significant if Bonferroni correction is considered. In addition, rs11205591 and rs10891319 polymorphisms showed an additive interaction with BMI and obesity risk. CONCLUSIONS: Several polymorphisms from genes coding MRC proteins may be involved in BMI variability and could be related to the risk to become obese in the Spanish general population.

RESUMO

Familial combined hyperlipidemia (FCH) is a primary atherogenic dyslipidemia with insulin resistance and increased cardiovascular risk. Plasminogen activator inhibitor type 1 (PAI-1) and myeloperoxidase (MPO) activity are associated with proinflammatory and atherothrombotic risk. Our aim was to study the role played by PAI-1 and MPO activity in the carotid atherosclerosis prevalence in FCH subjects. 36 FCH unrelated subjects (17 women) were matched by age and body weight with 36 healthy normolipidemic subjects (19 female). Blood lipids, glucose, insulin, insulin resistance (homeostasis model assessment (HOMA)), MPO, and PAI-1 were determined in both groups. Carotid intima media thickness (IMT) was measured by the same investigator by standardized protocol. No differences in age, body mass index (BMI) or waist circumference were observed between the two groups. HOMA and PAI-1 values were higher in the FCH group, reaching statistical significance in those subjects with insulin resistance. In addition, PAI-1 values correlated significantly with metabolic syndrome components and carotid IMT. It is known that the elevated cardiovascular risk that characterizes FCH is frequently associated with insulin resistance. We have detected that two known proinflammatory and proatherothrombotic factors (MPO and PAI-1) are significantly elevated in FCH subjects with insulin resistance. These results could partly explain the high cardiovascular risk present in FCH subjects.

RESUMO

INTRODUCTION: The potential impact of targeting different components of an adverse lipid profile in populations with multiple cardiovascular risk factors is not completely clear. This study aims to assess the association between different components of the standard lipid profile with all-cause mortality and hospitalization due to cardiovascular events in a high-risk population. METHODS: This prospective registry included high risk adults over 30 years old free of cardiovascular disease (2008-2012). Diagnosis of hypertension, dyslipidemia or diabetes mellitus was inclusion criterion. Lipid biomarkers were evaluated. Primary endpoints were all-cause mortality and hospital admission due to coronary heart disease or stroke. We estimated adjusted rate ratios (aRR), absolute risk differences and population attributable risk associated with adverse lipid profiles. RESULTS: 51,462 subjects were included with a mean age of 62.6 years (47.6% men). During an average follow-up of 3.2 years, 919 deaths, 1666 hospitalizations for coronary heart disease and 1510 hospitalizations for stroke were recorded. The parameters that showed an increased rate for total mortality, coronary heart disease and stroke hospitalization were, respectively, low HDL-Cholesterol: aRR 1.25, 1.29 and 1.23; high Total/HDL-Cholesterol: aRR 1.22, 1.38 and 1.25; and high Triglycerides/HDL-Cholesterol: aRR 1.21, 1.30, 1.09. The parameters that showed highest population attributable risk (%) were, respectively, low HDL-Cholesterol: 7.70, 11.42, 8.40; high Total/HDL-Cholesterol: 6.55, 12.47, 8.73; and high Triglycerides/HDL-Cholesterol: 8.94, 15.09, 6.92. CONCLUSIONS: In a population with cardiovascular risk factors, HDL-cholesterol, Total/HDL-cholesterol and triglycerides/HDL-cholesterol ratios were associated with a higher population attributable risk for cardiovascular disease compared to other common biomarkers.

RESUMO

Low physical activity (PA), or sedentary lifestyle, is associated with the development of several chronic diseases. We aimed to investigate current prevalence of sedentariness and its association with diabetes and other cardiovascular risk factors. PA was evaluated in a population-based, cross-sectional, randomly sampled study conducted in 2009-2010 in Spain. International Physical Activity Questionnaire (SF-IPAQ) was used to assess PA. 4991 individuals (median age 50 years, 57% women) were studied. Prevalence of sedentariness was 32.3% for men and 39% for women (p < 0.0001). Sex differences were particularly notable (age*sex interaction, p = 0.0024) at early and older ages. Sedentary individuals had higher BMI (28 vs. 27 kg/m2) and obesity prevalence (37 vs. 26%). Low PA was present in 44, 43, and 38% of individuals with known diabetes (KDM), prediabetes/unknown-diabetes (PREDM/UKDM), and normal glucose regulation (p = 0.0014), respectively. No difference between KDM and PREDM/UKDM (p = 0.72) was found. Variables independently associated (p < 0.05) with sedentariness were age, sex, BMI, central obesity, Mediterranean diet adherence, smoking habit, HDL-cholesterol, triglycerides and dyslipidemia. Low PA is on the rise in Spain, especially among women. Sedentariness is associated with several cardiovascular risk factors and may be responsible for the increasing prevalence of obesity and diabetes in this country.

RESUMO

AIMS: To evaluate the changes in glycemia, insulinemia, and oxidative stress markers during an oral fat load test in nondiabetic subjects with abdominal obesity and to analyze the association between postprandial oxidative stress markers and postprandial glucose and insulin responses. METHODS: We included 20 subjects with abdominal obesity (waist circumference > 102 cm for men and > 88 cm for women) and 20 healthy lean controls (waist circumference < 102 cm for men and < 88 cm for women). After 12 hours of fasting we performed a standardized fat load test (0-8 hours) with supracal® (50 g/m2). We determined metabolic parameters, oxidized and reduced glutathione, and malondialdehyde. RESULTS: In both groups, insulin, HOMA, oxidized/reduced glutathione ratio, and malondialdehyde significantly decreased in the postprandial state after the OFLT. All these parameters were significantly higher in the abdominal obesity group at baseline and during all the postprandial points, but the reduction from the baseline levels was significantly higher in the abdominal obesity group. CONCLUSION: Unsaturated fat improves insulin resistance and oxidative stress status. It is possible that a consumption of unsaturated fat could be beneficial even in subjects with abdominal obesity in postprandial state.

RESUMO

BACKGROUND: Thioredoxins (TRX) are major cellular protein disulphide reductases that are critical for redox regulation. Oxidative stress and inflammation play promoting roles in the genesis and progression of atherosclerosis, but until now scarce data are available considering the influence of TRX activity in familial combined hyperlipidaemia (FCH). Since FCH is associated with high risk of cardiovascular disease, the objective of the present study was to assess oxidative stress status in FCH patients, and evaluate the influence of insulin resistance (IR). MATERIALS AND METHODS: A cohort of 35 control subjects and 35 non-related FCH patients were included, all of them nondiabetic, normotensive and nonsmokers. We measured lipid profile, glucose and insulin levels in plasma, and markers of oxidative stress and inflammation such as oxidized glutathione (GSSG), reduced glutathione (GSH) and TRX. RESULTS: Familial combined hyperlipidaemia subjects showed significantly higher levels of GSSG, GSSG/GSH ratio and TRX than controls. In addition, FCH individuals with IR showed the worst profile of oxidative stress status compared to controls and FCH patients without IR (P < 0·01). TRX levels correlated with higher insulin resistance. CONCLUSION: Familial combined hyperlipidaemia patients showed increased TRX levels. TRX was positively correlated with IR. These data could partially explain the increased risk of cardiovascular events in primary dyslipidemic patients.

RESUMO

INTRODUCTION AND OBJECTIVES: Di@bet.es is a national study designed to estimate the prevalence of diabetes mellitus and other cardiovascular risk factors in the Spanish adult population. The prevalence of hypertension and the degree to which it is recognized, treated, and controlled are described. METHODS: The study included a sample of the Spanish population with 5048 adults aged ≥ 18 years. Patients were questioned and examined, with 3 blood pressure readings while seated and at rest to calculate the mean of the 3 readings. Hypertension was defined as systolic blood pressure ≥ 140 mmHg and/or diastolic blood pressure ≥ 90 mmHg and/or prescription for antihypertensive drug therapy. RESULTS: Hypertension was found in 42.6% of the Spanish adult population aged ≥ 18 years and was more common among men (49.9%) than women (37.1%). The prevalence was higher among prediabetics (67.9%) and diabetics (79.4%). Undiagnosed hypertension was identified in 37.4% of patients and was more common in men (43.3%) than in women (31.5%). Among patients with known hypertension, 88.3% were receiving drug therapy. Well-controlled blood pressure was found in only 30% and was more common among women (24.9%) than men (16%). CONCLUSIONS: The prevalence of hypertension in Spain is high, and a considerable percentage of hypertensive patients have still not been diagnosed. Hypertension is associated with diabetes and prediabetes, and although drug therapy is increasingly common, the degree of control has not improved and remains low. Population campaigns should be developed and promoted for hypertension prevention, detection, and treatment.

RESUMO

Clinical guidelines should be based on the best available evidence and are of great importance for patient care and disease prevention. In this respect, the 2013 American College of Cardiology/American Heart Association report is highly appreciated and well-recognized. The report included critical questions concerning hypercholesterolaemia, but its translation into a clinical guideline initiated intense debate worldwide because of the recommendation to switch from a treat-to-target approach for low-density-lipoprotein-cholesterol to a statin dose-based strategy.

RESUMO

Treatment with statins has transformed primary and secondary prevention of cardiovascular disease (CVD), including thrombotic stroke. Evidence-based data demonstrate the benefits and safety of statin therapy and help to guide clinicians in the management of populations at high risk of CVD. Nevertheless, clinical trials, meta-analyses and observational studies highlight a 10-12% increase in new-onset diabetes mellitus (NODM) among patients receiving statins. The risk further increases with intensive therapy and among individuals with known risk factors for NODM. Mechanisms underpinning this effect are not yet fully understood; however, Mendelian randomization studies suggest that they are related to lowered activity of HMG-CoA reductase, the target of statin therapy. In vitro research indicates that statins potentially impair ß-cell function and decrease insulin sensitivity but how these findings relate to patients is unknown. In the clinic, statins should be prescribed on the basis of CVD risk and individual patient characteristics. In addition, diet and lifestyle interventions should be emphasized to help mitigate the risk of NODM. Individuals who develop NODM while taking statins do not exhibit increased microvascular disease, which is reassuring. In diabetes mellitus of long duration, the effect of statins on glycaemic control is small and unlikely to be clinically important.

RESUMO

The authors present their view on the prevention of cardiovascular diseases, accepting the European ESC/EAS guidelines. They consider that the aim of the lipid control, based on LDL-C goals, is essential for the prevention and treatment of cardiovascular diseases. In subjects with metabolic syndrome (mainly, abdominal obesity, pre-diabetes and diabetes), the primary objective should be apoB or Non-HDL-C, which are better associated with cardiovascular risk. The treatment must be lifestyle changes and control of other risk factors. After calculating cardiovascular risk, statins are the first therapeutic step, with the strength and dose needed to achieve LDL-C goals. If targets are not achieved, ezetimibe or resins should be added. A new group of potent cholesterol-lowering agents, the PCSK-9 monoclonal antibodies, have recently been approved in Spain. Subjects at very high cardiovascular risk that have achieved LDL-C goals, or other objectives (apoB, Non-HDL-C), other drugs (fibrates, omega-3) capable of modifying triglycerides and HDL-C could be added, if necessary. Treatment to reduce cardiovascular risk and prevent cardiovascular disease has proven effective in all populations and at all age groups. Subjects older than 80years should be individually assessed, taking into consideration possible comorbidities.

RESUMO

OBJECTIVES: Familial hypercholesterolemia (FH) is characterized by increased oxidative stress (OS) levels. In the postprandial state, lipids and lipoproteins modulate OS status through their impact on pro-oxidant and antioxidant mechanisms. The objective of this study was to evaluate in patients with FH the response to an unsaturated oral fat load test (OFLT) by analyzing the mRNA levels of genes involved in the glutathione and thioredoxin antioxidant systems. DESIGN AND METHODS: We analyzed 14 FH patients and 20 normolipidemic and normoglycemic controls. In both groups, mRNA values of antioxidant enzyme genes (glutathione and thioredoxin systems) were determined at baseline and at 2, 4, 6, and 8h after OFLT by real time PCR. RESULTS: In the fasting state the mRNA levels of antioxidant enzymes GPX4 and the GSR, GSS, and GCLC enzymes (involved in glutathione regeneration and synthesis) and thioredoxin (TXN), were significantly increased in the FH group compared to the healthy controls. Some genes (GPX1 and GPX4) were increased at 4h in both groups, but values for the rest of the antioxidant enzyme mRNAs were decreased in FH patients after 4h from unsaturated OFLT and were increased in controls. CONCLUSIONS: We concluded that an OFLT with predominantly unsaturated fat has a different effect on postprandial antioxidant enzyme mRNA levels in controls than in FH patients. Increased antioxidant enzyme mRNA is not the main way to reduce postprandial oxidative stress in FH. This difference could determine the influence of dietary patterns in these patients.

RESUMO

OBJECTIVE: The aim of this study was to examine possible associations between ambient temperature and obesity in the Spanish population using an ecological focus. METHODS: The Di@bet.es study is a national, cross-sectional, population-based survey of cardiometabolic risk factors and their association with lifestyle. SAMPLE: 5,061 subjects in 100 clusters. VARIABLES: Clinical, demographic and lifestyle survey, physical examination, and blood sampling. The mean annual temperature (°C) for each study site was collected from the Spanish National Meteorology Agency (1971-2000). RESULTS: The prevalence rates of obesity in the different geographical areas divided according to mean annual temperature quartiles were 26.9% in quartile 1 (10.4-14.5°C), 30.5% in quartile 2 (14.5-15.5°C), 32% in quartile 3 (15.5-17.8°C), and 33.6% in quartile 4 (17.8-21.3°C) (P = 0.003). Logistic regression analyses including multiple socio-demographic (age, gender, educational level, marital status) and lifestyle (physical activity, Mediterranean diet score, smoking) variables showed that, as compared with quartile 1, the odd ratios for obesity were 1.20 (1.01-1.42), 1.35 (1.12-1.61), and 1.38 (1.14-1.67) in quartiles 2, 3, and 4, respectively (P = 0.001 for difference, P < 0.001 for trend). CONCLUSIONS: Our study reports an association between ambient temperature and obesity in the Spanish population controlled for known confounders.

RESUMO

BACKGROUND AND AIM: Prevalence rates of "metabolically healthy obese" (MHO) subjects vary depending on the criteria used. This study examined the prevalence and characteristics of MHO subjects and metabolically abnormal normal-weight subjects and compared the findings with the NHANES 1999-2004 study. The aims of the present study were, first, to determine the prevalence rates of MHO and MNHNO subjects using the same criteria as those of the National Health and Nutrition Examination Survey (NHANES) (1999-2004) study, and second to compare the prevalence and correlates of obese subjects who are resistant to the development of adiposity-associated cardiometabolic abnormalities (CA) and normal-weight individuals who display cardiometabolic risk factor clustering between the Spanish and the US populations. METHODS AND RESULTS: Di@bet.es study is a national, cross-sectional population-based survey of 5728 adults conducted in 2009-2010. Clinical, metabolic, sociodemographic, and anthropometric data and information about lifestyle habits, such as physical activity, smoking habit, alcohol intake and food consumption, were collected. Subjects were classified according to their body mass index (BMI) (normal-weight, <25 kg/m(2); overweight, 25-29.9 kg/m(2); and obese, >30 kg/m(2)). CA included elevated blood pressure; elevated levels of triglycerides, fasting glucose, and high-sensitivity C-reactive protein (hs-CRP); and elevated homeostasis model assessment of insulin resistance (HOMA-IR) value and low high-density lipoprotein cholesterol (HDL-c) level. Two phenotypes were defined: metabolically healthy phenotype (0-1 CA) and metabolically abnormal phenotype (≥2 CA). The prevalence of metabolically abnormal normal-weight phenotype was slightly lower in the Spanish population (6.5% vs. 8.1%). The prevalence of metabolically healthy overweight and MHO subjects was 20.9% and 7.0%, respectively, while in NHANES study it was 17.9% and 9.7%, respectively. Cigarette smoking was associated with CA in each phenotype, while moderate physical activity and moderate alcohol intake were associated with being metabolically healthy. Olive oil intake was negatively associated with the prevalence of CA. CONCLUSIONS: Smoking, physical activity level, and alcohol intake contribute to the explanation of the prevalence of CA in the Spanish population, as in the US population. However in Spain, olive oil intake contributes significantly to the explanation of the variance in the prevalence of CA.
