Case histories of four elderly patients with central nervous system signs of digitalis toxicity were reviewed. Evidence of toxicity included lethargy, depression which was not present previously, confusion, restlessness, emotional instability, hyperventilation, and vertigo. Vomiting developed four days after the onset of the mental changes. No cardiac arrhythmias were observed. Digoxin serum levels ranged between 4.2 and 7.0 ng/ml. Serum potassium values were within normal limits. Three of the four patients recovered with a return of their mental status to the pretoxic state. The fourth case was fatal. At autopsy long-standing myocardial ischemia was the only significant finding.

Forty-four cases with myocardial rupture (33 with free wall rupture, 9 with interventricular septal perforation and 2 with papillary muscle rupture), all of which were ascertained by autopsy and/or at surgery, were analyzed. When the following 7 risk factors were actively managed in the acute stage of myocardial infarction, the incidence of myocardial rupture was significantly reduced: a) high blood pressure on admission, b) physical and emotional instability, c) recurrent chest pain, d) aged females, e) no history of angina or myocardial infarction, f) large myocardial infarction on ECG and g) the first 10 days after the attack of myocardial infarction. If cardiogenic shock occurs, surgery should be performed as soon as possible; if not, it should be delayed 3 weeks. The natural history of ischemic heart disease was analyzed in 400 medically-treated patients with significant coronary artery disease. They had been followed up continuously and periodically for more than one year. The prognosis of the patients with 3-vessel disease or left main trunk disease, those with poor left ventricular function (EF less than 30%) and of old age (greater than or equal to 60) and those who had a history of ischemic heart disease was poor. Follow-up study was done in 30 patients with variant angina. They often had life-threatening arrhythmias during attacks (8 ventricular tachycardia or ventricular fibrillation, 8 serious bradyarrhythmia). All patients with variant angina should be treated medically at first, and only patients with organic coronary artery disease and chest pain on effort in spite of the medical treatment should be considered as candidates for AC bypass surgery.
