Observational study of hypertension in Matelica, Italy (Matelica hypertension study)
No full textThis study summarizes the results of an epidemiological investigation carried out on the occasion of the Second World Hypertension Day (May 13, 2006) in the city of Matelica in the Region of the Marches, Central Italy. In all, 518 subjects (298 males, average age 52.3 years; 220 females, average age 55 years) with either diagnosed hypertension or who were thought to be normotensive had arterial blood pressure measured. Other cardiovascular risk factors and the costs of pharmacological treatment for hypertension were assessed as well. In 72.46% of examined subjects, arterial blood pressure levels averaged > or =140-90 mmHg if non-diabetic and > or =130-80 mmHg if diabetics. A total of 48.14% of individuals assumed in anamnesis to be normotensive had arterial blood pressure levels higher than the above values and were therefore found to have hypertensive values. The cost of anti-hypertensive treatment in the area of Matelica averages Euro 543.7/patient/year. The present data, which are in line with those of other epidemiological studies performed in Italy, confirm the view that arterial hypertension control in Italy is still largely unsatisfactory. This observation should stimulate both health and specific medical measures to counter the risk of complications of arterial hypertension in aged populations, such as those present in the territory examined

No full textAsymptomatic left ventricular systolic dysfunction in essential hypertension - Prevalence, determinants, and prognostic value
No full textPrevalence, determinants, and prognostic value of asymptomatic left ventricular systolic dysfunction (LVSD) in uncomplicated subjects with essential hypertension are still incompletely known. We studied 2384 initially untreated subjects with hypertension, no previous cardiovascular disease, and no symptoms or physical signs of congestive heart failure (CHF). These subjects were studied at entry and followed for up to 17 years (mean 6.0). Asymptomatic LVSD (ALVSD), defined by an echocardiographic ejection fraction <50%, was found in 3.6% of subjects. Cigarette smoking (P = 0.013), increased left ventricular (LV) mass (P = 0.001), and higher 24-hour heart rate (P = 0.014) were independent correlates of ALVSD. During follow-up, a first cardiovascular event occurred in 227 subjects, and 24 of these events were hospitalizations for symptomatic CHF. Incidence of CHF per 100 persons per year was 0.12 in patients without and 1.48 in patients with ALVSD (log-rank test P = 0.0001). In a Cox model, after adjustment for age (P = 0.0001), LV mass (P = 0.0001), and cigarette smoking (P = 0.039), LVSD conferred a markedly increased risk for CHF (odds ratio, 9.99; 95% confidence interval, 3.67 to 27.2). Incidence of coronary (0.84 versus 0.62 × 100 person years) and cerebrovascular (0.80 versus 0.62 × 100 person years) events did not differ (all P = NS) between subjects with and without ALVSD. ALVSD is a potent and early marker of evolution toward severe CHF requiring hospitalization in subjects with essential hypertension. © 2005 American Heart Association, Inc
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
