[Nuclear medical determination of left ventricular diastolic function in coronary heart disease].
In 191 patients with confirmed coronary disease we determined the left ventricular diastolic function with the Nuclear Stethoscope by the aid of the Peak Filling Rate (PFR) and the Time to Peak Filling Rate (TPFR). Moreover we investigated the ejection fraction (EF). 123 patients had already suffered a myocardial infarction, of these 59 an anterior wall infarction and 64 an inferior wall infarction. The remaining 68 patients had a CAD without a history of myocardial infarction. The PFR was 2.20 +/- 0.64 EDV/sec in the 59 patients after anterior wall infarction and 2.64 +/- 0.82 EDV/sec in the 64 patients after inferior wall infarction and 2.83 +/- 0.84 EDV/sec in 68 patients with coronary artery disease without a history of myocardial infarction. The TPFR was 178 +/- 36.7 msec after anterior and 157 +/- 49.2 msec after inferior wall infarction and 156 +/- 47 msec in the patients with CAD without previous infarction. The left ventricular diastolic function (PFR and/or TPFR) was abnormal in 87% after anterior wall infarction and in 81% after inferior wall infarction. In comparison with this the ejection fraction was reduced in 66% in anterior and in 61% after inferior wall infarction at rest. These results indicate that the resting diastolic function appears to be more informative for evaluation of a left ventricular dysfunction than the systolic function at rest.
