[Incidence and clinical symptomatology of coronary heart disease in acquired valvular defects].

220 consecutive patients with acquired valvular defects were checked within the preoperative examination by means of heart catheter with regard to significant coronary stenoses. In these cases a relative frequency of typical and atypical angina pectoris troubles of 0.136 and 0.459, respectively, was the result. In contrast to this significant coronary stenoses could relatively infrequently made evident angiographically: 6/220 (= 0.027). In patients with valvular defects angina pectoris cannot be used as the leading symptom of an additionally existing coronary heart disease on account of bad sensitiveness.
