Prospective study of a self-report type A scale and risk of coronary heart disease: test of the MMPI-2 type A scale.

abstract：BACKGROUND:Although clockwise rotation and counterclockwise rotation are distinct findings of the ECG, their prognostic significance is rarely studied. METHODS AND RESULTS:We studied prognostic values of clockwise and counterclockwise rotation on total, cardiovascular disease (CVD), and subtype mortality using the Nat...
