| Popis: | In order to assess the incidence of silent myocardial ischaemia, 190 consecutive patients with cerebral ischaemia and without symptoms or electrocardiographic signs of ischaemic heart disease, underwent a maximal exercise treadmill test. Patients with a positive exercise test were submitted to exercise thallium myocardial scintigraphy. Results were compared with those obtained in a control group of 113 healthy subjects submitted to the same study protocol. An adequate exercise test was obtained in 140 patients with cerebral ischaemia. The exercise test was positive in 36 cases (26%). The end points were exhaustion in 24 patients, ST segment depression greater than or equal to 3 mm in seven and systolic blood pressure greater than or equal to 240 mmHg in five. The exercise thallium myocardial scintigraphy was normal in three and abnormal in 33: reversible perfusion defects were detected in 26 cases and fixed defects in seven. In the control group, matched for age and sex, the exercise test was positive in only seven cases (6%; P less than 0.01); the exercise myocardial scintigraphy was normal in five and abnormal in two subjects. In conclusion, in a remarkable proportion of middle-aged patients with cerebral ischaemia, silent myocardial ischaemia can be detected by means of noninvasive cardiologic investigations. |
