Psychosocial correlates of atrial natriuretic peptide: a marker of vascular health.

Background: Psychosocial factors have been associated with cardiovascular outcomes, but few studies have examined the association between psychosocial function and natriuretic peptides.

Purpose: The purpose of this study is to determine the predictive value of hostility, anger, and social support in relation to atrial natriuretic peptide (ANP), a marker of vascular health, among middle-aged men.

Methods: One hundred twenty-one men (mean age = 39.

Usefulness of heart rate to predict cardiac events in treated patients with high-risk systemic hypertension.

A high heart rate (HR) predicts future cardiovascular events. We explored the predictive value of HR in patients with high-risk hypertension and examined whether blood pressure reduction modifies this association. The participants were 15,193 patients with hypertension enrolled in the Valsartan Antihypertensive Long-term Use Evaluation (VALUE) trial and followed up for 5 years.

Predicting arterial stiffness with ambulatory blood pressure: an 11-year follow-up.

No prospective data have been published on whether ambulatory blood pressure (BP) works better than casual measurements in predicting arterial stiffness. This study with 11-year follow-up was launched to evaluate the usefulness of ambulatory intra-arterial BP in predicting pulse wave velocity (PWV). Ninety-seven previously healthy men were recruited from a routine physical check-up at baseline.

Metabolic syndrome and arterial stiffness: the Health 2000 Survey.

Metabolic syndrome and its components have been associated with arterial stiffness and cardiovascular disease. The objective of this study was to examine the independent influences of metabolic syndrome, its components, and other cardiovascular risk factors on arterial stiffness as well as to compare 2 definitions for metabolic syndrome (National Cholesterol Education Program [NCEP] and International Diabetes Federation [IDF]) in their ability to identify subjects with arterial stiffness. The study population consisted of 401 Finnish men and women aged 45 years and older who participated in a substudy of the Finnish population-based Health 2000 Survey.

The Valsartan Antihypertensive Long-Term Use Evaluation (VALUE) trial: outcomes in patients receiving monotherapy.

In the main Valsartan Antihypertensive Long-Term Use Evaluation (VALUE) report, we investigated outcomes in 15 245 high-risk hypertensive subjects treated with valsartan- or amlodipine-based regimens. In this report, we analyzed outcomes in 7080 patients (46.4%) who, at the end of the initial drug adjustment period (6 months), remained on monotherapy.

Asymmetric dimethylarginine and hemodynamic regulation in middle-aged men.

The goal of this study was to evaluate the role of asymmetric dimethylarginine (ADMA) in the regulation of hemodynamic functions in hypertensive men. It has been suggested that ADMA, as an endogenous nitric oxide synthase inhibitor, is linked to hypertension and vascular reactivity. Sixty-seven men aged 51.

Gender differences in the treatment and secondary prevention of CHD at population level.

Objectives: Treatment and secondary prevention measures, received by persons with coronary heart disease (CHD), are insufficiently known at the moment. The aim of this study was to investigate the state of treatment and secondary prevention of CHD in a population-based sample and to analyze possible gender differences in different age groups.

Design: 300 men and 300 women with CHD were identified from a nationally representative health examination survey with 88% participation rate, carried out in Finland in 2000-2001.

Impaired myocardial function in newly onset type 2 diabetes associates with arterial stiffness.

Aim: The aim of this study was to evaluate myocardial function using pulsed and color-coded tissue Doppler imaging (TDI) and vascular wall elasticity using whole-body impedance cardiography (ICG) in patients with newly diagnosed Type 2 diabetes mellitus (DM2), and to compare the measurements with those of healthy controls.

Methods: Systolic (SBP) and diastolic (DBP) blood pressure and glycosylated hemoglobin (HbA1c) were measured in 49 men (mean age 52.3+/-5.

Atrial fibrillation in elderly patients after cardiac surgery: postoperative hemodynamics and low postoperative serum triiodothyronine.

Objective: The purpose of this study was to evaluate serum triiodothyronine levels as a trigger of postoperative atrial fibrillation (AF) in elderly patients undergoing cardiac surgery and to study the possible association of serum triiodothyronine levels with preoperative and postoperative hemodynamics.

Design: Prospective study.

Setting: University hospital.

Comparison of treatment benefit and outcome in women versus men with chronic heart failure (from the Valsartan Heart Failure Trial).

The comparison of treatment effect and co-morbidity between the genders in the Valsartan Heart Failure Trial showed equal benefit of treatment in men and women. Co-morbidities, such as diabetes and coronary artery disease, increased nonfatal cardiac morbidity more in women than in men.

Psychological stress tasks in the prediction of blood pressure level and need for antihypertensive medication: 9-12 years of follow-up.

Increased blood pressure (BP) reactivity to subtypes of psychological stimuli may differentially predict the development of future BP elevation or hypertension. The authors present the 9-12-year follow-up results of 82 (86%) of 95 male participants with different BP levels. They were healthy, untreated, and age-matched volunteers from a routine health checkup carried out on all 35-, 40-, and 45-year-olds from a medium-sized city.

Comparison of patients with acute coronary syndrome with and without systemic hypertension.

The role of systemic hypertension in acute coronary syndrome (ACS) has not been well studied. We studied consecutive subjects admitted to the University of Michigan Health System (Ann Arbor, Michigan) with symptoms of ACS. Data were collected using a standardized form.

Pulse pressure responses to psychological tasks improve the prediction of left ventricular mass: 10 years of follow-up.

Objectives: To examine the role of casual blood pressure measurements and blood pressure responses to psychological tasks in the prediction of future left ventricular mass index (LVMI), and to determine the importance of different components of blood pressure, and the predictive value of an individual's personal characteristics and antihypertensive medication on future LVMI.

Methods: At baseline, blood pressure was recorded by casual measurements; during tests it was recorded by intra-arterial monitoring. The participants were healthy, untreated 35-45-year old men.

A "gender blind" relationship of lean body mass and blood pressure in the Tecumseh study.

Background: Body size correlates positively with blood pressure (BP) but there is controversy about the roles of obesity versus muscularity in this relationship.

Methods: We examined the BP relationship with overweight, lean body mass (LBM), and muscle performance in 231 adolescents (17.25 +/- 3.

Atrial fibrillation after coronary surgery: comparison between different health care systems.

Aims: No studies have evaluated the influence of management strategies in different health insurance environments on atrial fibrillation (AF). This observational study compared the incidence of and treatment strategies for postoperative AF after primary coronary bypass surgery.

Methods And Results: One insurance and one public funded location was compared: University of Michigan Health Center (USA, n=272) and Tampere University Hospital (Finland, n=314).
