The heart in hypertension: unresolved conceptual challenges. Special lecture.
Much has been learned over the past 25 years concerning the role of the heart in hypertension. In a multiplicity of areas a great deal has been clarified but a number of issues remain unresolved. This personal overview outlines some of these challenging areas for investigation, including questions relating to the cardiogenic reflexes, mechanisms underlying total body autoregulation that may involve not only the adaptation of arterioles but also venoconstriction in hypertension, postcapillary constriction also involving the efferent glomerular arterioles, the mechanisms underlying the development and regression of hypertrophy as well as the function of the hypertrophied and "regressed hypertrophy" heart, and the precise hemodynamic actions of atrial natriuretic factor.
