RESUMEN

INTRODUCTION: Cardio-cerebrovascular (CCV) disease contributes significantly to the global burden of disease, with dramatic consequences in terms of mortality and general health. Mitigate CCV risk factors is the key to reduce individual and population risk of CCV events. Evidence-based medicine and epidemiological investigations of risk factors are essential to optimize actions. AIM: To contribute to the knowledge of the burden of risk factors in determining CCV events in the individual patient and in the community. METHODS: Clinical data and risk factors were collected through a longitudinal survey (1999) as part of a larger epidemiology and cardiovascular prevention project, namely the "VIP (Valle dell'Irno Prevention) Project". We assessed the incidence of major cardiovascular events (MACE) and for each risk factor we calculated: prevalence, absolute risk, odds ratio (OR), additional risk (AR) = risk of exposed to the risk factor - risk of non-exposed, population attributable risk (PAR) = additional risk * prevalence, population attributable risk fraction (PAF) = PAR/total incidence of the disease. RESULTS: Comparing the MACE group with the non-MACE group, a statistically significant difference was found for the following: glomerular filtration rate (GFR), glucose and systolic blood pressure (SBP), BMI, diastolic blood pressure (DBP), cholesterol, triglycerides, creatinine and uric acid. GFR, glucose and SBP showed the highest OR. Age, creatinine, glycemia, SBP and uric acid were independent predictor of MACE. When calculating the PAF, the CCV risk factors with the greatest impact on MACE were: SBP (29.6%), triglyceridemia (19.4%) and metabolic syndrome (18.3%). CONCLUSION: The burden of risk factors on MACE changes substantially according to whether it is calculated in the single patient or in the population. It is crucial for physicians to take these differences into account when applying their own intervention to reduce CCV events.

RESUMEN

BACKGROUND: Vitamin D (25(OH)D) deficiency is a prevalent condition worldwide. However, the highest prevalence rates of 25(OH)D deficiency have been attributed to regions with higher latitude. A close association between 25(OH)D and cardio-cerebrovascular (CCV) risk factors and major health problems has been identified. AIM: To establish the prevalence of 25(OH)D deficiency and to investigate the relationship between 25(OH)D levels and CCV risk factors (blood cholesterol, triglycerides, glucose concentrations, body mass index, and systolic and diastolic blood pressure) in a cohort representative of Southern Italy. METHODS: The prevalence of 25(OH)D levels was evaluated in 1200 subjects aged 25-74 years (600 males and 600 females), enrolled in the "VIP" (from Italian for Irno Valley Prevention) Project, whereas multiple linear regression analysis was used to determine the relationship between 25(OH)D levels and CCV risk factors. RESULTS: Only 13.3% of females and 11.1% of males showed adequate serum concentrations of 25(OH)D (≥30 ng/ml), while 59.3% of females and 55.1% of males showed 25(OH)D deficient levels (<20 ng/ml). We observed an independent association between 25(OH)D concentrations and metabolic syndrome score, LDL cholesterol, HDL cholesterol, and corrected QT (cQT). CONCLUSIONS: We report a high prevalence of 25(OH)D deficiency across the largest Italian adult population studied so far and, in particular, the first across Southern Italy; furthermore, we provide data on the association between 25(OH)D deficiency and higher CCV risk factors.

RESUMEN

Similar to other peripheral artery diseases, vessel narrowing in popliteal artery entrapment syndrome (PAES) reduces the ankle brachial index (ABI). Since the PAES is related to several anatomical or functional variations, we sought to determine if the ABI was correlated with the type of syndrome. Through a systematic review of literature, we identified case reports and series in which the diagnosis of PAES was accompanied by ABI measurement. Twenty-seven studies included in the qualitative synthesis described 87 limbs. The most common types of the syndrome were those caused by an abnormal medial head of the gastrocnemius (type II, n = 35, 40.23%) and aberrant course of the popliteal artery (type I, n = 20, 22.99%). The variation of plantaris muscle (n = 7, 8.05%) is currently not included in the classification system. The median value of ABI was 0.87 (interquartile range (IQR) = 0.6-1.0). There were no differences among types of syndrome (F = 0.13, p = 0.72). In conclusion, despite clinical recommendations, the ABI remains underused in PAES diagnosis. No correlation was detected between the index score and type of syndrome. The cases of PAES involving structures other than the gastrocnemius or popliteus muscle suggest the need to revisit the current clinical classification system.

RESUMEN

AIMS: To date, whether hyperuricemia may represent a marker or an independent risk factor for cardiovascular disease remains unclear. This study aimed at assessing the role of hyperuricemia in the onset of major cardiovascular events (MACE). METHODS: Baseline clinical data were collected through a 1998/1999 longitudinal survey as part of the larger Valle dell'Irno Prevenzione Project. Ten years later, MACE incidence was evaluated. RESULTS: A total of 1175 patients (50% men, aged 25-74 years) completed the study. At least one MACE was reported by 135 patients, whose mean uric acid values were significantly higher compared with patients without events (6.0 ±â€Š4.8 and 4.6 ±â€Š4.0 mg/dl, respectively; P < 0.01). Patients with uric acid values of at least 6 mg/dl (prevalence of 14.6%) had significantly lower levels of high-density lipoprotein cholesterol and increased values of BMI, blood pressure (BP), cholesterol, triglycerides, white blood cells, complement component 3 (C3) and creatinine. After subgrouping patients in tertiles and considering the first one as reference [odds ratio (OR): 1], the OR (95% confidence interval) was 1.44 (0.7-2.9) in the second and 2.2 (1.3-3.5) in the third tertile, respectively. Confounder-adjusted stepwise linear regression revealed uric acid, age, creatinine, glucose and systolic BP as independent predictors of MACE. Diastolic BP and creatinine were independently correlated with uric acid in the entire population, diastolic BP only in men and BMI, creatinine, age and C3 in women. CONCLUSION: Hyperuricemia was shown to be a strong independent risk factor for MACE and should be included in cardiovascular prevention strategies. Whether hypouricemic drugs can decrease cardiovascular disease risk warrants further studies.

RESUMEN

The aim of this study was to determine the trends of cardiovascular risk factor prevalence between 1988/9 and 2008/9 in the 25-74-year-old population in an area of Southern Italy. We compared three cross-sectional studies conducted in random population samples, in 1988/9, 1998/9, and 2008/9 in Salerno, Italy. The methodology of data collection (lipid profile, systolic and diastolic blood pressure, glycaemia, and smoking) and conducting tests which the population underwent during the three phases was standardized and comparable. Prevalence of diabetes, hypertension, hypercholesterolemia, and smoking was calculated and standardized for age. A total of 3491 subjects were included. From 1988/9 to 2008/9, in males, the prevalence of all four risk factors was reduced. In women, there was a clear reduction of hypertension, a similar prevalence of hypercholesterolemia, and an increase of smoking and diabetes. In the area of Salerno, our data confirm that the global prevalence of the major risk factors is decreasing in men, but their absolute values are still far from optimization. In women, diabetes and smoking showed a negative trend, therefore requiring targeted interventions. These data are now used as a base for executive targeted programs to improve prevention of cardiovascular disease in our community.

RESUMEN

BACKGROUND: Data relating to non-fatal cardiovascular events are poor but these data are essential to organize targeted interventions on the territory and to understand their effectiveness. METHODS: We calculated the rates of morbidity from cardiovascular events covering the period 1998/99-2008/09, in a cohort of 1200 persons (600 men and 600 women) aged 25 to 74 years. Data were standardized using the European standard population. RESULTS: The incidence of events to ten years of non-fatal myocardial infarc.ion was 2.2% in men and of 1.8% in women. PCI interventions to ten year have been 3.3% in men and 3.4% in women, the interventions of aorto-coronary bypass have been 2.4% and 0.5% for men and women respectively. While all major cardiovascular events have been more frequent in men, in women there was a higher incidence of stroke (1.6% vs 0.9%). CONCLUSION: Although by comparison with other European countries Italy is among the countries considered at low-risk of coronary heart disease, in Campania cardiovascular diseases reach higher rates than the rest of the country. Our results are in keeping with the literature data and confirm that cardiovascular diseases are a major public health problem. Local analysis are useful in providing additional information for planning prevention interventions targeted to its own territory.

RESUMEN

AIM: To examine trends of uncontrolled total serum cholesterol, treatment and control in a Mediterranean region (Campania). METHODS: We considered and compared the data collected as part of "Montecorvino Rovella Project" 1988-1989 and cross-sectional data from the two phases of the "VIP Project-Valle dell'Irno Prevenzione": 1998-1999 (1(st) phase) and 2008-2009 (2(nd) phase), in the 35-74-year-old-population. RESULTS: Data show a reduction of mean cholesterolemia in the last twenty years of 7.3 mg/dL for men and unchanged values for women. In the three surveys the mean values for serum cholesterol are in men: 205.2 ± 47.1 mg/dL (1988/89), 200 ± 38.9 mg/dL (1998/99) and 197.9 ± 40.2 mg/dL (2008/09); in the women: 203.1 ± 42.5 mg/dL (1988/89), 198.9 ± 37.9 mg/dL (1998/99) and 203.3 ± 39.3 mg/dL (2008/09). Prevalence of uncontrolled high cholesterol ≥ 240 mg/dL for men decreased from 20.8% (1988/89) to 14.3% (1998/99) and 13.9% (2008/9), P = 0.002; for women the values decreased from 19.9% (1988/89), to 18.2% (1998/99) and 18.1% (2008/09), P = 0.007. Is statistically increased the number of patients treated and those treated to target. CONCLUSION: Encouraging increases in awareness, treatment, and control of hypercholesterolemia occurred from 1988 through 2008. Nevertheless, control of hypercholesterolemia remains poor.

RESUMEN

RATIONALE: In Italy the mortality data were obtained almost exclusively from the data RENCAM (Name Causes of Death Register), while there are few prospective surveys. In order to assess whether there are particular epidemiological conditions in the geographical area of Mercato S. Severino, in Southern Italy, we have studied, and reassessed at ten years (1998/99 - 2008/09), a cohort of adult general population in a project of cardiovascular epidemiology and prevention. MATERIALS AND METHODS: We calculated the rates of mortality and morbidity from cardiovascular events covering the period 1998/99 - 2008/09, in a cohort of 1200 persons (600 men and 600 women) aged 25 to 74 years. Data were standardized using the European standard population. RESULTS: Mortality from cardiovascular causes was 46.5% in men and 48.7% in women; it was mainly concentrated in the age group 65-74 years where it occurred on 62.9% of deaths in men and 66.7% in women. Regarding morbidity, the incidence of events to ten years of non-fatal myocardial infarction was 2.2% in men and of 1.8% in women. PTCA interventions to ten year have been 3.3% in men and 3.4% in women, the interventions of aorto-coronary bypass have been 2.4% and 0.5% for men and women respectively. While all major cardiovascular events have been more frequent in men, in women there was a higher incidence of stroke (1.6% vs 0.9%). CONCLUSIONS: Although by comparison with other European countries Italy is among the countries considered at low-risk of coronary heart disease, in Campania cardiovascular diseases reach higher rates than the rest of the country. Our results are in line with the literature data and confirm that cardiovascular diseases are a major public health problem. Local analysis to propose means to provide useful information for planning prevention interventions targeted to their own territory.

RESUMEN

UNLABELLED: Current American Academy of Pediatrics Guidelines recommended that statins should be considered as a first-line agent in children as early as 8 years of age. The aim of our work is to assess the safety of 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors in children with hypercholesterolaemia. CONCLUSION: Controlled studies in children show that statin monotherapy is efficacious, well tolerated and safe in the short-time. Unfortunately, these studies have relatively short-term follow-up periods, and therefore, long-term safety remains unclear.

RESUMEN

Chronic kidney disease (CKD) is a common disorder whose prevalence is increasing worldwide. In Italy the prevalence of CKD, especially the early stages, is still not exactly known. Our study examines the prevalence and trends in ten years (1200 subjects in 1998-1999 and 1200 subjects in 2008-2009) of the estimated glomerular filtration rate (eGFR) in a population of southern Italy. We analyzed, within the VIP project, the prevalence of CKD (eGFR <60) in our area and its relationship to diabetes and hypertension as well as the trend between the years 1998-1999 and 2008-2009. The estimate of the GFR was obtained with the Cockcroft-Gault formula corrected for body surface area. The prevalence of CKD, stratified by the population of Campania, was about 5.9% in males and 3.9% in females in the years 1998-1999; ten years later (2008-2009) it had increased to 6.2% in males and 4.5% in females. The differences between males and females and between the two decades are not statistically significant although the trend shows a clear increase in subjects affected by CKD among both sexes. Among the male population the prevalence of CKD in persons with hypertension or diabetes, in those with both diseases, and in those free from these diseases was 11.2%, 12%, 13.8% and 6.3% (p=0.018), respectively. The same groups among females showed a CKD prevalence of 8%, 9.2%, 9.7% and 4.4%, respectively (p=0.042). Our work provides a picture of the prevalence of CKD in an area of southern Italy. It highlights the increase in CKD and calls upon a greater use of renal function tests in clinical practice, so that individuals at increased risk of developing cardiovascular complications may be detected as early as possible.
