Effect of activation of the H1 receptor on coronary hemodynamics in man.

abstract：BACKGROUND:Computed tomography (CT) allows estimation of coronary artery calcium (CAC) progression. We evaluated several progression algorithms in our unselected, population-based cohort for risk prediction of coronary and cardiovascular events. METHODS:In 3281 participants (45-74 years of age), free from cardiovascul...
