    ABSTRACT: The Center for Health Discovery and Wellbeing (CHDWB) is an academic program designed to evaluate the efficacy of clinical self-knowledge and health partner counseling for development and maintenance of healthy behaviors. This paper reports on the change in health profiles for over 90 traits, measured in 382 participants over three visits in the 12 months following enrolment. Significant changes in the desired direction of improved health are observed for many traits related to cardiovascular health, including BMI, blood pressure, cholesterol, and arterial stiffness, as well as for summary measures of physical and mental health. The changes are most notable for individuals in the upper quartile of baseline risk, many of whom showed a positive correlated response across clinical categories. By contrast, individuals who start with more healthy profiles do not generally show significant improvements and only a modest impact of targeting specific health attributes was observed. Overall, the CHDWB model shows promise as an effective intervention particularly for individuals at high risk for cardiovascular disease.

    ABSTRACT: Hypertension has been established as one of the commonest causes of heart failure especially in sub-Saharan Africa. We have previously observed a high prevalence of left ventricular (LV) systolic dysfunction in hypertensive heart failure patients in Nigeria despite a low prevalence of ischemic heart disease. The present study was, therefore, undertaken to assess the prevalence of asymptomatic LV systolic dysfunction in hypertensive black African subjects with no history of heart failure. One thousand nine hundred forty-seven hypertensive subjects without heart failure presenting to the Cardiology Unit, Department of Medicine, University of Abuja Teaching Hospital, Nigeria, from April 2006 to August 2013 had clinical and echocardiographic evaluation. Nine hundred fifty-three (48.9%) were males and 994 (51.1%) were females. One thousand eight hundred seventeen (93.3%) had normal LV systolic function (LV ejection fraction (LVEF) ≥ 54%), 68 (3.5%) had mild LV systolic dysfunction (LVEF 45-54%), 43 (2.3%) had moderate LV systolic dysfunction (LVEF 30-44%), and 16 (0.9%) had severe LV systolic dysfunction (LVEF < 30%). Male subjects had worse LV systolic function compared to women (mean LVEF 73.2% vs. 75.6%, P value < 0.0001) and diabetic subjects had worse LV systolic function compared to nondiabetic subjects (LVEF 72.3% vs. 75.7%, P = 0.02). In multivariate regression analysis, lower LVEF as a continuous variable was associated with older age, male sex, diabetes mellitus, LV mass indexed for body surface area, diastolic blood pressure, posterior wall thickness in diastole, left atrial diameter, and LV internal diameter in diastole. In a cohort of asymptomatic Black hypertensive subjects, 6.7% had LV systolic dysfunction, which was associated with male gender, diabetes mellitus, and larger LV mass. © American Journal of Hypertension, Ltd 2015.
