[Invasive diagnosis of coronary heart disease in patients over 75 years old].
Between January 1, 1993, and August 31, 1995, 268 patients over 75 years underwent coronary angiography at the University Hospital of Bern. Their clinical reports were analyzed in order to determine whether invasive diagnosis of coronary artery disease (CAD) is justifiable also in the elderly considering risks and complications. The main indication for coronary angiography were symptoms of ischemic heart disease. Twenty-nine underwent the procedure for planned cardiac surgery, mostly valve replacement. In 79% of patients, coronary angiography revealed CAD. In the remaining 21% there were no significant coronary stenoses, but 82% of them had valvular heart disease. Only 4% had neither coronary nor valvular heart disease. Following coronary angiography 63% of patients had a therapeutical intervention: 24% coronary angioplasty (PTCA), 13% bypass-grafting, 17% valve replacement, 8% combined surgery (revascularization and valve-replacement), and 1% another intervention. Four percent had no cardiac disease, 1% died before a planned surgery. The remaining 32% were continued on medical therapy. As indicators of appropriateness and success of the invasive procedure the rates of complications and the duration of hospitalization were analyzed. The incidence of deaths, myocardial infarctions, cerebral complications, and arrhythmias was five to ten times higher for cardiac surgery than for PTCA or conservative treatment. Invasive diagnosis and therapy of CAD in patients over 75 years can nevertheless be reasonable and successful if the decision is taken carefully considering risk factors and concomitant disease.
