The -930G allele of p22-phox has been associated with higher promoter activity, increased NAD(P)H oxidase-mediated oxidative stress and hypertension. We recently reported that(More)
Normotensive and hypertensive subjects with and without left ventricular (LV) hypertrophy (LV mass index [LVMI] >51 g/m(2.7)) were examined by conventional echocardiography and tissue Doppler imaging of mitral annulus motion. The subgroups included nonobese normotensive subjects (n=16; age 51+/-9 years; 11 female; systolic blood pressure [SBP] 109+/-11 mm(More)

AIM This study was to verify the psychometric properties of the Heart Valve Disease Impact on daily life, an instrument for measuring the impact of illness in the daily life of the heart valve disease patient, related to its construct validity, criterion-related validity and reliability. METHODS One hundred and twenty heart valve disease outpatients were(More)
The main purpose of this study was to identify the correlation between health-related quality of life and the Functional Independence Measure (FIM) in elderly patients with heart failure. 146 elderly outpatients completed the Minnesota Living with Heart Failure Questionnaire (LHFQ) and the FIM. Spearman correlation coefficient was used to identify(More)
This study compared measures of quality of life (QOL) in two groups of coronary heart disease patients: one with myocardial infarction (MI) and one with angina (A). The population studied consisted of 49 patients from Group MI and 27 patients from Group A. A questionnaire was used to identify socio-demographic and clinical data, as well as data from the(More)
The objective of this study was to verify content validity and reliability of "CAV-Instrument" -- an instrument to measure beliefs and attitudes of heart valve disease patients concerning their illness and treatment.
