Five dialysis patients with residual hypertension were treated with a new sustained-release formulation of propranolol (160 mg per capsule) in a dosage of 1 to 2 capsules per day. Four of these patients developed persistent cold, numb, blue and clumsy fingers. The symptoms resolved when the drug was withdrawn.

Three renal patients with transplant kidneys and uncontrolled hypertension were treated with intravenous doses of labetalol. Only minor depressor effects were noted and tachyphylaxis developed in 1 patient. Other parenteral hypotensive agents reduced blood pressure satisfactorily.

This report summarizes a four-year experience with 60 patients who had left ventricular aneurysm (LVA) resection and bypass of all significantly diseased coronary arteries, with an operative and late mortality of 3.3 and 8.3%, respectively. Their cardiac catheterizations were reviewed, and the only values that seemed to reflect prognosis were preoperative cardiac index and the presence of absence of septal motion. The lower the cardiac index, the less likely the patient was to do well postoperatively. There were now survivors who had lacked septal motion by left anterior oblique ventriculogram. Patients without septal motion are therefore no longer considered surgical candidates. If septal motion is present, resection of LVA carries no more risk than myocardial revascularization without LVA.
